Rfq For Shims

[Bamban]

I am looking for one of you folks to cut a small run of shims for my project.

Thickness 0.001

OD - 0.740, + 0.005

ID - 0.625, + 0.003

Quantity - 24 pieces.

The dimensions are really loose whatever you can cut within the range. Shims they are what they are, whatever the tolerance they come in is fine.

Thank you.

I think you want bushings rather than shims---have you looked at copper tubing sizes to see if any come close to your needs? ----but, look at your specs---it's impossible to to have a 0.740 OD and a 0.625 ID and a 0.001 side wall. Perhaps you can post a sketch of what you need and it would clarify it .

Bamban,

Did you find what you needed? I have made these type of shims by modifying stainless steel shims from McMaster.

Think of it as a washer.

I was going to suggest that buying 3/4" x 1/2" shims from McMaster (under $1.00 each) and punching out the ID. But you listed the max OD as 0.740". However, it just occurred to me that you could make a shouldered mandrel with clamping washer and use a tool post grinder to reduce the OD of all 24 pieces in one operation.

I've used these guys in my past for metal stampings. They also do waterjet cutting also. Maybe able to waterjet some .001" thick washers for you.

These guys start at .005" thick. You could always surface grind them to .001" thick!
