I need to get a pair of EN36 shims cased, local place only does vacuum heat treatment.
I am near Gatwick airport. Anyone know of place near me?

I eventually bit the bullet and drove up to Walton, had just the couple of small items not much bigger than a tuppence, the bloke wanted 58 quid plus vat!

If you told the robbing ******* where to shove it, you could try Cray Valley Heat treatment. just off J3 (M25).

No quite polite, I might end up there another time...
Think I am sorted, someone from the forum is going to get them done.
I am wondering about heat treating stuff myself, I haven't considered an
oven as it all seemed to much hassle, but it is probably worth it.

depends what you want to treat... if its flat/round bar and you just want to case harden, then a decent propane torch and some case hardening compound (http://cgi.ebay.co.uk/1-KG-Case-Hardening-Compound-Replaces-Kasenit-/370232975495) and a copy of this book (http://cgi.ebay.co.uk/HARDENING-TEMPERING-HEAT-Model-Engineers-Book-/190443388479)

I have tried kasenit, my grandad used to case stuff in the kitchen range using it. I might
still have his can of the stuff; I take it carbon and bicarb doesn't have a sell by date;-)
The gearbox is full of new parts, and I am wary of varying from what was stock, I was tempted
to make a spacer fram gauge plate, then harden it and temper it in the oven. I could buy a new part,
but the supplied part is 24 thou to thin and the best way of setting the endfloat in this case is a
spacer/shim of the right thickness.
Might get that book, I love a nice book.
