Re: Rat repair.
Got the last of the spotwelds done last night, still need to grind them down and give a last look for any areas I missed. A pic from the side, still really happy with the rate of shrinking, and no oil canning. While doing this I was thinking about ways to keep the heat minimized without blowing air or using a wet rag which we know is not a good idea, in machining if your cutting correctly 90-95% of the heat comes off the part within the chip, so I decided to try using a new sharp die grinder bit to knock the spotwelds down, slow and tedious but I do think it helped keep the heat off the part if nothing else by only working a smaller area at a time.
While on the subject I'd like to know which Rolex disks you guys like to use? I have been using the 3M green disks In different grits, but I really don't know if one type is better for steel and another for aluminum??
