Your work is getting tight Randy , I could flight you to the windy City for some garage time LOL:)
I think the shrinking disc would be the wonders for this panel . I wish I had one to run it over on

Yeah, Bobby, I'm intrigued. I just watched this video about a shrinking disk... Wolfes Metal Fabrication Shrinking Disc demonstration - YouTube Thanks!
When we went to the Reno swap meet about 6 years ago we watched them beat the crap out of a fender and pull the dents back out with a shrinking disk, just amazing how quick he was with it.
Does it matter how big the shrinking disc is? I've seen 4" & 9" available. I only have a 4" angle grinder....will the 4" disc be big enough for what it needs to do on my lid?
Thanks...
Randy I want to say it was a four inch disc, but that was long ago, its a memory thing now...:LOL:
During my internet 'wanders' I saw where someone had made a shrinking disc out of common pieces of steel. While not as glamorous as the $50 version, will work well. There are a bunch of threads if you Google.
And for once Randy, trying to SAVE you $$$ instead of the usual
As Dave said home made will work , you are really just creating heat thru friction , so a home made one would be fine . Dave I like that idea myself . The stainless is just harder and won't wear as bad is all I would think .
Bobby - after I 'penned' my response to Randy, I removed a worn out solid edge 7" saw blade from my tile saw and may just see if I can make that into a shrinking disc. There is still a tiny bit diamond grit on the edge, but it may come loose with some heat and may anneal the disc enough to be dished a little bit. Low on my list of things to do though :-/
I have a 4" hole saw and some 16 gauge steel. Could I just cut a disc, drill a 5/8" hole to fit my angle grinder the dimple it a bit and make it a little concave?
That angle grinder will be too fast - mine runs at 11,000 rpm - and will end up burning. The hole saw might come apart at the weld. I would be using my big Hitachi grinder/polisher which runs 600-3600 rpm and probably at some speed around 2000 or where ever it 'felt right'.
Hey Dave, just for clarification, I was only going to use the hole saw to cut out a 4" disc, not as part of the shrinker. you know, sorta like eating the donut hole instead of the donut...:D
One of the sites suggested taking the shrinking disc up to 6000rpm for faster heating of the area.
I have a Makita 5" disc sander that runs 4500rpm. If I can figure out a way to make a disc for that it might work well. Will let you know....
