Mmm, buying shims befor have actually measured the right clearance not seem to me a right approach, as on an engine with age the valves can settle deeper on the seats, but also the cams/buckets will wear out... Who knows what of the 2 will win? Acually isn't rare to find some with less and some...
I've found this:
www.precisionshims.com.au
They have quoted me 6.00AU$ per shim (in any measure that i want)...
Plus 20$ of shipping!!
Seem quite cheap...
Are the only one that i've found that made shims on order...
For a set of 16 i spend 96+20+some custom duties (say 25%), and i pay near...
Hmm... but it's in america, and i must add custom duties...
Else, this will be fine?

304 steel would be good?
And is also quite cheap...
And, yes, they type k is a thermocouple :) Can...
I've access to some wood/carbon stove, that must reach quite high temperatures... I can pack them in the steel foils with the type k sensor inside, and mading a sort of support for choosing the best height inside the stove for finding the right temperature, can this work?
So i need a bar of s7...
Mmm, i have an infrared thermometer, and also a 1000°c type k temp reader, and i can buy a poldi hardness tester quite cheap...
I don't need to do a big quantity of shims, only a set (also for future regulations).
Surely isn't the best setup, but can be ok for made my own?
Until now i've...
I've tryied to buy a 4ch model helicopter, but it need much patience that what i have :) After it has crashed a couple of times on some walls, i've abandoned :) And that was after a lot of hour on the simulator! I'snt the right hobby for me, i'll prefer engine tuning :) I'm mading all by myself...
Mhauuaua, Benesesso :):):) You have learned the most useful words needed here in italy!!! :):)
So, you have also visited Asti!
I'll hope that you have nice memories about my nation/city :)
Ahahah, you was here in italy? Nice! :)
I'm from Asti (well known in the world for our wine, and for the 'Palio of Asti'), it's 60km from turin, and about 150km from milano...
And, where you live now?
I've not access to a surface grinder, but surely i can get someone to grind them for me. I've 'only' direct access to a firends lathe and mills, both cnc and manual.
I'm from italy (and my english isn't that good :):) )
Yes, this was also an idea that i've had, but would be nice to be able do my own shims :(
So do you think that in this application a prehardened s7 stell isn't good?
This isn't for sure my best drawing, but must be quite clear how a typical shim underbucket works:

If you prefer, i can upload some photos.
The shim is the black thing just placed under the bucket, and over the valve tip, and it must be...
I know that is elementary mechanical engineering, but i don't have made any study on this area... And i'm learnig something in this days, as i've this throuble :)
The engine is a Subaru EJ20...
Bending must not be an issue, the shim on the other side is 'attached' due to superficial tension of...
This are really useful infos :) Really thanks!
Mmm, but the oem shims, that are 2.00mm, and surely are heat treated/quenched, can have an hardened layer that leave intact the core of the steel?
Because on the net i've readed that this shims must be only case hardened, but i don't imagine how is...
I have some britemor 4455 and a wood light, i'd suppose it will suffice. A case hardening is possible on a 1..5 diameter, 2mm thick shim? I'm thinking about this, but i'd suppose that it's quite difficult to obtain a precise case hardened on that small part...
Else i can use normal tool...
Really thanks for the suggestion, really quite interesting! I'll take a look on the whole site if i can find something that can be good for me!
Only a note, 11.5mm is the diameter of the shim, the thickness must be 0.9.
I've fear that using full hardened shims it can broken due to be too...
Hi!
I've done some work on the seat of an engine head, and now i can't find any shim that can i use for setting the valve clearances.
The clearance is set by a 11.5mm in diameter diameter shim that is placed just under the bucket, between the bucket and the valve stem.
The minimum shim that i...
