What's up guys? I am trying to install my YT UL's on my TFS 235's. Well the shim supplied was not enough to get a good wipe pattern in the middle of the valve. So I added another washer that I had laying around to get the correct wipe pattern. The needed thickness is .100". I don't want to stack washers, just seems like a bad idea. I called McMaster-Carr and couldn't find exactly what I needed. The main problem is with tolerance variance. The thicknesses, what ever they may be, have a .020" variance. That is way too much for what I am needing. All the shims/washers that came in the YT kit are exactly .047". I need that kind of accuracy. The washers I need are 5/16" x 3/4" x .100" Or 8mm x 19mm x 3mm. Who sells true machine flat washers that are accurate. I kind of need an answer like yesterday. So any help would be greatly appreciated. Thanks.
