Wanted - titanium shim for slightly ovalized headtube

[[email protected]]

Anyone know where I can get a small 7 inch strip of titanium, w/ a
width of 3/16" , and .05mm thickness, to help solve an ovalized
headset problem?

TI frame, so I'm hoping for a ti shim.

Are you fitting a Ti headset? If so, are you sure you are in
possession of the appropriate Ti ball bearings?

Before you proceed, consider that a carbon fiber shim is lighter,
faster, and smoother-riding.

Ovalized headtube? No shim is going to be a long term fix..only getting
a new headtube BUT how on earth did a ti headtube get ovalized? Or did
it come like that?

By any chance, is this a head tube with a zero-stack headset?

I don't think I've ever seen any metals supplier list Titanium shim
stock.... McMaster-Carr (online) sells small precut pieces of it in
various metals, but not anything in Ti.

I would go with the stainless but tin snips may not cut it well
(stainless can be damn tough stuff). A Dremel-style moto-tool with a
thin cutting wheel will rip right through it easily and pretty cleanly
if your hand is stable.

I don't know of a source of Ti shim stock, but you probably
would want something much softer, such as brass, for shimming an
"ovalized", loose fitting cylindrical part.

However, better still:

Loctite #680 Cylindrical Mounting Liquid (Excellent for your type of
problem..fills gaps up to .015" 4000lb shear, yada yada yada etc.)
Uses acetone primer.
http://loctite.com Search for #680 under "Retaining Compounds"

I have used this product on ovalized heads and enlarged suspension
mounting holes with great success.


Also,Devcon makes a Titanium Putty product if you must have a product
with Ti in it.

Bottom line recomendation for large gaps.. JB Weld from the local ACE
store.
http://jbweld.net/products/jbweld.php

Any of these products will work better than a hard shim as they tend
to flow into the irregular voids and also provide some bonding action
as well.

Hope this helps..
Let us know how you make out!
