Does anyone know an inexpensive source of shim stock. I discovered that my 3 in 1 mill head was sagging. I was able to correct the problem with layers of aluminum foil but I expect that stuff will eventually "flow" with the stress. I need something in the order of .002"

Depending on what size of shim you need, you might find a cheap feeler gauge to be the best source of hardened shim stock, in a variety of sizes.

I wouldn't worry about shims "flowing." Even paper often makes adequae shims. Hardware stores carry brass shim stock in small qty's, the bigger ones have stainless steel as well.

Yep, if it's OK now, I'd leave it alone.
I bought the brass shim stock assortment from Travers a couple years ago and it has worked out well for me. .001 or .002 up to .031 in 6x12 sheets. Somewhere around $20.

Yeah, the "shim assortment" from Travers, or MSC, or Reid Tool, or any number of other places is probably the most reasonable way to go.

I agree with Randy and others though; I don't think you need to worry about the aluminum "flowing" on you, and if it's okay now, leave it alone.

Ok, thanx. I'll leave it alone but keep an eye on it.

Rmatel,

You will not need to worry about the foil compressing - you would need around 50Tons of pressure to really damage it.

One thing you should be aware of is electro-chemical corrosion with the dissimilar metals over a period of time. It is not really critical in your application, but you should know about it. The easiest way to prevent this in your case is a small amount of Zinc (a sacrificial anode) in with the Aluminum.

Just thought you may want to know about it.

One place here that sells shim stock is GBS (general bearing service). Another bearing place would probably have it. I price out one of those shim stock kits that snorman was talking about. It was 350.00 cdn at GBS. So the paper things sounds good to me

Good grief! MSC has a 12-pc steel shim stock assortment of thicknesses from 0.001" to 0.015" for about 20 bucks.

Spkrman, you need to get one of those Travers catalogs. Or any good tool supplier will do. They're good for a reference if nothing else. Lots of nice pics of all tools so you can see at a glance what people are referring to. Travers is good if you want to order too. I think you can order a big catalog online at www.travers.com. (http://www.travers.com.) Probably the same for other tool suppliers.

Gents,

In Canada, KBC is cheaper than Travers new 2002 Canadian catalog (for now). Other Suppliers are Kennametal, Sowa Tool (my Fav - great guys)- aka STM, Thomas Skinner & sons and many others - just check the yellow pages.

KBC has ALWAYS screwed my order up somehow.

I get most of my goodies from Thomas Skinner. I get good pricing and outstanding service.

If you want to buy US side do check www.thomasregister.com (http://www.thomasregister.com) for the best suppliers.

I have purchased brass and copper sheet in crafts and hobby stores cheaper than some tooling suppliers. Always look for the same for less...

Thanks guys. I was sure there was a cheaper solution. I figured that paper would slowly rot away in a garage, so i haven't taken that route yet. Well live and learn...back out to level the lathe bed some more...you can never be too acurate. Patience right http://bbs.homeshopmachinist.net//smile.gif
