Especially if I drill the pipes and fit some small copper pins through them ???
Night races should prove spectacular!! I'm loving the copper wire/pins idea also... Hmmmm..

The guy who makes them is very good. I told him that I could not slide them onto the axle case so they would have to be made to slip on from behind. I gave him the tube diameter and he got to work on his cad and laser machine. When they arrived I was a little confused at first because I did not understand why they did not just have a U shaped cut out to go over the axle case? Then it became obvious :) You cut off the odd looking part, flip it over and then slide it on from the other side to enable a full weld around the axle tube.. Brilliant :)
I was going to buy some sheet steel and then spend many many hours in the garage cutting, grinding, drilling and filing with the hope of making 4 brackets that might be similar. But for the sum of £53.00 these were made and delivered in 3 days. At this price for 4 brackets it was not worth me even attempting to make them myself.

That's a very innovative use of what would otherwise be a piece of scrap, or with a sloppy fit if he simply made the piece complete and sent instructions to cut out that front piece. Your friend is a good designer, and laser cutters are awesome tools.
I hope all you folk have had a great Christmas so far ??
We had a great Christmas day at home. Myself and the wife + our 4 Children and partners + mother in law.
Then on Boxing day the same again + my wifes brothers and sisters + children saw us once again filled to capacity with 23 for dinner and lots of fun and games up to about midnight when folks drifted off back to their homes in various parts of the UK.
Friday was a day of rest for all of us. And today I got the MG towed to a friends workshop (as my truck has broken down) and got the Roll Cage welded in and the Zoomies finished. My Truck wont be fixed until Monday so I cant actually test fire the new exhaust until then. I've hogged out the header flanges now to match the ports on the heads. The stock header exhaust flanges are 22mm wide. My head exhaust ports are 28mm wide + a few mm taller as well.
I know these dimensions sound small compared to USA heads on bigger motors but its enough for me at this time :)
The Zoomies have been wrapped in heat tape to just under the hood line. Lambda probes are now re fitted into the front pair and the EGT probes will be going into the rear pipes real soon. The new Hoosier Slicks are here and will be fitted next week onto my old 70's Slot Mags to get the MGB ready to rock for the first outing on 18th Jan for the Paul Walker Tribute day at Santa Pod Raceway. Then on the 19th for a RWYB test day.
I still have a big list of jobs to be done for 2014 but these will have to be done as time allows over the next few months. As the car stands now she is ready to race again. I have not made my usual mistake of starting 10 jobs over winter when I can really only finish 4 of them. I still need to finish the wheelie bar installation and fit the new transbrake gearbox. But those jobs will get done during next season after I have got some runs in. My weekends are getting consumed by work which pays the bills eh? So I'll just fit in my car works as time allows.
I'll be happy to hit the strip next month with fresh slicks and the Zoomies fitted so I can do some tuning.
As you can see in the picture. I have also finished the rain proofing for the new pipes. No rain is gonna get down these pipes in a hurry eh ?

Happy Holidays Pel Nice work.
ahhhhhhhhhhh---those were the days---either tennis balls or beer cans for the headers
Happy New Year folks !! :)
I managed to finish fitting the zoomies and also got some nice new Hoosier slicks fitted. I also did a few minor jobs which needed doing.
I took the car to Santapod on Saturday 18th Jan to attend the Paul Walker tribute day. This was a fund raiser that Santapod agreed to host for free for around 140 car clubs who wanted to do something. Santa pod reduced the entry ticket price from £10 to £4 to get folk into the venue. All entry ticket proceeds went to Paul Walkers charity "Reach Out World Wide" . The amount donated to ROWW was just under £29,000.00 or approx $48,000.00 so that was good I guess.
The down side was that all the cars on site were pretty much road cars and not 1/4 mile cars. I guessed that I would not get much track action due to cars dropping shafts and tranny's on the start line. But this was not the case. The race director made a decision not to glue the track so we could get as many cars down the strip without breakages. So I knew that I wasnt going to do much when I decided to roll the MG into the fire up lane. I didnt mind because over 7000 people got to watch a days racing and drifting + all the other things that were laid on. There was a 4 wheel drive lambo that managed a full power pass to reel in 11.2 seconds I think. That made the crowd very happy. Then fat boy Pel rolls up in the MG for a go on the new Hoosiers :) As expected she broke loose within a few seconds and decided that she wanted to run in the left lane instead. I backed out just enough to get off the nitrous and she then decided she wanted to do a Salsa dance with a hard back end wiggle ? So I just tickled it to the 1/8th and shut off. She managed to run a 12.1 by coasting for nearly the last 1/8th which was good.

I spoke to the race director about the Sundays RWYB and he said that the track would be fully prepped. So I rolled out at about 1pm on the Sunday for a proper pass. The engine tune was the same as last year and the track was pretty good despite it being just 47 degree's F. They had to work from 7am to 1pm to get the track dry enough to glue as we have had so much rain that moisture keep seeping up onto the track. So I had a first test pass and ran a 9.6 with no real drama. I was happy with that as it got me straight back on the PB number from last year as a good start to the season.

Then I prepped the car for a second pass. But this time I decided to start and add some timing back into the engine. I had been running around 8 degree's retarded last year while testing. I'm not sure what the ign timing should be for this new build so I was running safe rich and safe on retard. I added just 3 degree's of timing and went back to the start line. And I have to say that I am very happy with the increase in power that the 3 degree's made. Sadly my Moser custom shafts were not as happy :(
When i hit the loud pedal the car just lit up and hit really hard for about 2 feet ??? The left hand shaft sheared off and the right hand shaft is twisted as hell !!

So I will now fit a pair of MGB 1800cc drive shafts to get me rolling for Sundays RWYB challenge round. I think I can leave the nitrous off and pull in some 12 second runs to get some points.
The new plan is to have Moser make some more shafts but this time with Ford 9" 31 spline ends. I have found a Ford mini spool kit that I think I can graft into the differential without too much hassle. That will give me a shaft that is 20% thicker that should be good for more power?
I've ordered the mini spool from Summit so I can see how much machining needs to be done fit it. This should be a fun project I think. Ford 9" parts grafted into my 39 year old MGB rear axle ??
Happy Days!
Pel
OUCH! Sticky new tires.. add in more power = parts consumption. I guess you found another weak link!
And we call this fun right?!?!? :LOL::LOL:
The second run was real nice. Sorry to hear about the broken bits, but I love watching the old MG fly down the track.
Greetings friends!
Here is the update from this evening in the garage !
I have shelved the Ford 9" side gear idea now. In fact I have dropped the idea of modifying my MGB diff to take Ford 9" shafts all together now. Mainly because I have fitted a Ford 9" spool into the axle case with very little effort ?
Ford spool bearing mounts = 1.78" O/D. MGB diff gear internal dimension = 1.77" nominal.
So two mins polishing the spool ends with fine grit paper and light oil is all that was needed. New MGB diff bearings in the oven at 200C for 20 mins saw them slipping on nice and snug. And within 10 seconds of cooling they were locked on hard.
Ford 9" spool is only 70 thou wider than the MGB diff cage. So it fits right in and I just need to shave 35 thou off each bearing shim to make it fit. And the spool flange face is only a few mm away from being in the right place to make my crown wheel / ring gear mesh perfectly with the pinion gear?
http://i205.photobucket.com/albums/b...psc199b8ce.jpg
http://i205.photobucket.com/albums/b...ps26cded20.jpg
With very little work indeed the Ford 9" spool drops in like it was made to be there ???
I have now paid for my 31 spline shafts which should be on their way from Procomp in California.
This is not the finished item. Buts its so close its almost funny to think that I would have been able to drop the spool into a stock MGB axle this easy ??
http://i205.photobucket.com/albums/b...ps468330dd.jpg
That's pretty cool! How did you decide to even try it? Had someone else tried it before?
I dont think anyone has tried before. I was playing with an old welded diff cage and my slingshot buddy said I should try a spool as its much neater. He had an old one in his garage that he dropped over before Christmas and its been on the floor until now. It wasnt until I pulled out a spare axle case to take measurements for the new shafts that I put the spool and the MG diff cage side by side on the table and saw that the bearings and flanges lined up pretty well. So we dropped it in loose and then decided to ditch the Minispool and Ford 8.8 side gear idea and go straight for fitting the big spool :) So I could have got this fitted over the Christmas holidays if I hadnt forgotten about it !! So far so good ;)
And now your idea is on the world wide web!!! I don't foresee me drag racing any MG's in the future but, who knows!! Maybe I'll "borrow" the idea!
Edison said it a long time ago,I'd say your idea qualifies!Quote:
Genius is one percent inspiration, and ninety nine percent perspiration.
Ha Ha!!
Thanks Guys :)
I like to share anything like this that I do because someone else could benefit. Especially someone with a British classic using this type of axle for a budget build. Phase 2 will be altering the brake end to see if that will drop on ok. I guess my easy way out for the wheels would be to find a pair of Ford 5 stud rims to take my slicks. I think the shafts come with holes for 5 x 4 1/2
and 5 x 4 3/4 pcd.
EXCITED NOW !!
I had my Saturday job cancelled so I hauled the rear end out of the MGB. I pulled the diff and removed the crown wheel / ring gear. Then re fitted the diff cage and used a straight edge across the flange to mark the casing. Then fitted the spool and marked the casing again. The result was two scribed lines with a gap of 7.9mm between them. So it will be 3mm off the back of the ring gear and 5mm off the spool flange to get the gears meshing where they were before.
Even after removing 5mm from the spool flange it will still be 5mm thicker than the existing MGB flange on the diff cage. I managed to finf my friend still at his machine shop at 2pm on Saturday so he now has all the parts to machine over the next few days. The fiddly part will be re drilling the spool flange (which is 10 bolts) to accept my 8 bolt ring gear. But thats what my mate Geoff does for a living at his machine shop :)
Sadly all this got done so quick I didnt think to take pictures DOH !!!
The bolt circle on the spool is larger than the bolt circle on the ring gear by just enough to be able to have the new holes drilled without any of the holes meeting each other. I'm now wondering if its possible to find a 9" spool as an un-drilled blank ? That would be nice...
I did nothing on the car today as I was at the track crewing and tuning for some friends and also helping my Son shakedown his race car after some winter mods. The weather was sunny and quite warm over here at 63F so we all had our jackets off :)
The cars are now tucked away and under cover so its cold beer while waiting for the Chinese to be delivered while I kick back and watch the "Greatest Drag Racing Movie Ever Made" from back in the day.. American Nitro, featuring the Mongoose and a host of other cars !!

Now thats what I call a good end to a Great day :)
Peace and love folks

WooHoo!! New Parts!!!
Hell Yeah !!!
The shafts are already at the machine shop being trimmed so my brake drums will fit. I'm going to use the 5x4.5" pcd for some new wheels.
I hope to have all the parts back in a week so I can start trial fitting before final adjustments :)
I just repaired the flattened spring mounts and braced them as well as welding the axle tubes to the diff casing.

Good Stuff there! TWICE!! LOL..
A small update !
Tonight was the first proper trial fit.
I wasnt far off with my guesstimate about where the shaft would end when fitted.
I had both shafts trimmed back to extend the area where the bearings will press on. I used a spare bearing and took the O/D down by 1.1mm on the belt sander so it was a slip fit in the casing. Then took about 4thou out of the bore of the bearing so it was a slide fit onto the shaft with just light pressure required to push it on by hand.
Then I fitted the bearing and brake back plate onto the axle case and slid the shaft in until it hit the stop up against the bearing.
It looks pretty darn good I must say :)
At least 5/8th" clearance for the back of the wheel studs, but I just need to trim a chamfer onto the back of the wheel flange to clear the bottom brake spring. Cant really see it in the pics but there is about 10thou clearance. I'm just worried about the spring vibrating and touching the flange. I fitted the brake assembly with temp bolts and nuts. When the brakes etc are fitted and the bearings pushed on I will have to fit the bearing retainer plate bolts from the rear and use a modified spanner to hold the nuts while I do it all up.
And you can see the shaft will need to be trimmed to size when the final fit is done. I cant do this until I have the spool back from the machine shop though. The splines in the spool are not central, so I'll need to measure and mark the outside of the spool to show where the splines are and then strike two marks onto the diff case so I can fit the shafts without the spool and mark the pints where I need to cut. This will be done on the loose fit bearings. When the shafts are cut (long on drivers side and short on passenger side for my UK car) I can then assemble the brakes etc and press the bearings into place on the shafts in my mates hydraulic press.
So far so good I think ??

Spool now ready for final fitting tests this weekend !!
I have had some issues with machining the hard steel. But i got it figured out in the end. Ring gear drops on and seems to fit nice and flat according to my marking out with the horrid blue stuff which gets everywhere :)
I have over bored the bolt holes so the cap head screws can be fitted with EN40 washers which we made in the machine shop on Monday from a stock bar that we trimmed, bored and paired in the lathe. This will give the best clamping force I think.
The project it becoming a little fragmented due to various factors. So we are doing small jobs out of sequence between my house, the machine shop and a friends garage. The net result is that all parts are slowly coming together to ensure that this holiday weekend should see the spool fitted and tested for correct mesh of the gears and also to determine the final measurements for the spool bearing side shims. I have enough shims to get me nearly there and I am cutting up feeler gauges and odd offcuts of shim stock to slip in beside the bearings in the casing to make sure I can measure the thickness required for both bearing shims. Once I have this measurement I will order two thick stock MGB shims and get them ground to the correct thickness next week.
I think this is the finished machine work on the spool ????
http://i205.photobucket.com/albums/b...ps18387f85.jpg
Silly Question?? But, why didn't you use the bolt holes with the larger circle? Did you not want to bore / tap the ring gear? Or was the layout unfavorable?
Have you tried to drill and tap a ring gear ?? :)Quote:

No, I cannot say that I've ever tried to bore or tap a ring gear? I think I could with a Bridgeport and solid carbide.. but maybe not?
And boring would only be half the process. Tapping threads would be a b_tch!! LOL..
I was really wondering if the bolt hole location was less than favorable moreso than the hardness.
Like I said............. a silly question! :3dSMILE::LOL::3dSMILE:
Man you'd have a hard time filling a ring gear let alone taping one. Don't know what the Rockwell is on them but they sure are hard
Hard on the outside.. tender on the inside... just like you! :LOL::LOL:
I don't know the Rockwell either. I was just curious as to which was the deciding factor for drilling the carrier.
Personally, I think having the bolts farther from center would've made it stronger but it's a moot point if the part cannot be bored/tapped. (well, at least easily!):3dSMILE:
Hi Guys!!
I think it ready for final trial fitting tomorrow :)
The counter boring made the bolts too long, so I ordered some shorter bolts and they came today. I will do some accurate measuring tomorrow to make sure the bolts are exactly right. I may use the 3/4" long threads that arrived today. Or I may grind down the 1" long threads that I had already. I want to be sure that when its all torqued up that I dont have any more than 1/16th gap between the end of the bolts and the bottom of the tapped holes in the ring gear. The wheel studs arrived today from Summit which is great. The confusing thing for me today was that the wheels studs come in packs of 5. But the wheel nuts and washers come in packs of 4. So I had to buy 3 packs of nuts and washers..... ?? I'm just happy that I have all I need for the holiday weekends work on the rear axle now. Not sure what wheel studs and nuts cost you guys over there, but they arrived at my house in the UK today for $148.00 all in. So apart from the 2 spare nuts thats just under $15 per stud and nut. How does that work out to what you guys would pay over there per nut and stud delivered??
Regards
Perry
I'd have to go look at Summit to see what the prices might be. I know the wifes car uses a lug nut that has a stainless cover on it and they are expensive.
The packs of 4 probably have something to do with folks buying a set of locking lugs that come in a pack of 4.
WELL!!!
Today was some good news and some bad news :(
The good news is that the spool is now fitted and shimmed and has what seems to be ideal mesh between ring and pinion according to my book about Ford axles and how to set them up. I know this isnt a Ford axle, but the instructions on how to check mesh between the gears is universal. I used white assembly grease as a marker and the mesh pattern seems to match up with the pictures in the book. I did end up swapping some shims around to get it right. But when all was torqued up it looked ok to me. Well as good as it can be on a ring and pinion with 120,000 miles on it ?
Regarding the studs and nuts:
It seems the parts from Summit would be $58 all in. So about $80 for mark up and shipping from a UK supplier. I can live with that. What I cant live with is the wrong studs being shipped to me. AARRRGGGHHH!!!!
I told the guy at the race shop in the UK that my holes in the wheel flanges were 0.590" They sent Moroso studs with splines at 0.594" which I can push in by hand. And with not a lot of force I can spin in the holes. So thats the whole axle build finished for this weekend unless I can get some more studs in a rush. Tomorrow I will call a few hot rod shops in the UK to see if they may have some studs in stock. It may be Saturday but these guys tend to have an on call person to open up the shop on a weekend if racers need parts. Last year we needed an MSD starter for the Slingshot as it burnt out on a Sunday. A fellow racer gave us the number of topspeed automotive near the track and the guy on call met us at the shop to sell us a starter motor :)
Maybe they will have some studs in stock?
I was hoping to be out next weekend for shakedowns, but if it doesnt happen I'll just bite the bullet and wait for what I need. I have to admit that I came close to pulling the studs into the wheel flange with nuts and spacers so I could weld them to the flange. But my friends at the garage held me down and shouted BAD IDEA at me :)
Stuff happens eh?
I'll be ready to roll when the time is right I guess :)
Regards
Perry
Pel, good work on fitting that ring gear and carrier in there! That really stinks about your studs. I hope you can find something that will be correct tomorrow.
So who's measure is wrong? I tend to think yours is "off a little" ??? Sucks when Murphy reaches out and grabs hold of your day...Quote:
