WOW... I still find that work to be amazing! Thanks for sharing also.

Holly cow! You do impeckable work! That is awesome!

Thanks for the comments guys. Sorry for the long hiatus, been too many distractions...

Media blasted the inside of the upper gate to clean it up before welding the new part on. Unfortunately this revealed more in the way of pits, through holes, etc., so it now looks like more fabrication....





Time to attempt some dies for the Lennox. Tonight's choice is some 1" thick phenolic sheet...





Here's the profile we're looking for...





The dies installed in the holders....








An offset bend was added to the sample 19ga in the brake, then the first of three passes.....





Final pass.....





Dies held up well....








Safety tip of the day, 3" roloc discs do a good job of shaping phenolic, so skin is no match.... (note thumb in above pic)



Where my "test sample" was made initially with straight bends in the brake, the actual piece on the lift gate is not straight, so the bends on the "good" piece will need to be bent using the tipping wheel.








The profile needs just a bit of tweaking, and I may try using a piece of metal inserted in a band saw blade cut to sharpen up some of the details.

Thanks, Robert! Every post is a Masters class in metal work and you always take time to take such great pics of it! Awesome!

What R2 said!! I was happy to see this thread active again and want to thank you for all the detail(s) you provide for us, it is very much appreciated!

I have to agree! I know very little of sheet metal shaping and very much enjoy your useful posts. So thanks so much!

Thanks for the comments fellas.

Checked the lower profile of the upper gate with radius sweeps to lay out the new piece...











Laying out the pattern on 19ga steel....








Tipping wheel in the bead roller...





......and a newly modified back stop, much better than the flat one.....





Offset added with the tipping wheel......





Then run through the Lennox.....








More tipping, then the step die used in place of skateboard wheel with the tipping wheel for the lower 1/4" fold...











Still need to fold the top in the window opening, until next time...

Fantastic job, you should churn some of those panels out and sell them.

Heck, I can hardly get this one finished


Tonight I made a small sample to test the fold of the window opening. I started off by producing a small pile of scraps.....about three tries unsuccessfully, then this one, beginning with using the bead roller tipping wheel....








This is about as far as it would go, and with the good piece already having bends at the bottom, would be a bit less once tried on that piece. This will require a custom made "anvil" for some hammer action...

As modified:














.....then for some manual tipping...











Comparison to the original....








This looks close, next task will be to cut a sample out of the original and see how close we actually are...

Thank you,really enjoy see step by step on this type of fab work!

Amazing! Thanks for sharing the tools made, too.

I would have a pile of scrap all over if I were trying to make a compound curved everywhere piece as you are! Keep ait it sir!!!

Simply amazing to be able to follow such a craftsman with outstanding skill and patience to not only manufacture his own patch panels but to make his own dies to be able to accomplish the job. Wow, I'm in awe of your skill sir, thank you for sharing.

Once again, the quality of craftsmanship represented here is just flat amazing Robert! Thanks for sharing. In so doing, you encourage others to take a bit of a plunge and try our hand at some fabricating.

Thanks for the comments guys. Well, that's about enough of the practice pieces, time to finish the rest of the bends. Just to make sure we don't need any "tweaking", I'll cut a profile sample out of the center. This spot weld one the inner flange is far enough away so I won't need to grind out a spot weld, and still have enough of that flange for a good measurement. In other words, removed with minimal effort where it still holds it's shape accurately.











Our profile template:





Just to compare to our test sample, looks like the inner flange was bent down a bit much in the manual hammering, will have to ease up a bit...





Outside profile looks good enough to leave alone!





Following the measurement used on the test sample, the panel is run through the bead roller's tipping wheel nice and slow to give us an initial mark for the bend, then repeated to tip the flange downward...








This looks about all we'll get without distorting and pulling, so then it's off to the custom anvil...














Then for some manual tipping...








...and comparing to our profile sample......





Ready to cut off the old next time...
