Hi, Whilst watching some videos on grinding your own valve seats, the guy was using a DTI gauge to check the concentricity of the valve seat. I can't seem to find such a tool from a UK supplier? They look like this. I have a DTI gauge and wondered about making one? |

for what the tooling costs I would rather juat get a machine shop to cut all the seats and valves on a Serdi machine or similar, no grinding required, just assembly, hell even let the machine shop fit the valves and springs with their air powered spring compressors.

I've always just checked them for play in the guide fixed that if its an issue and then looked at the pattern when grinding them in.

You can make one with a lever type dti. You need a mandrel that fits into the guide with no play. Then a part that holds your dti that slides over the madrel with no play. If you put a threaded stop on the part that rotates you can set your depth with that.
Good toolmaking exercise if your into that kind of thing. Probably going to. cost more than buying one in time tho I guess.

Might just have been lucky, but new guides and recut seats in an RS turbo head cost us £85 about a year ago
Superb job too 😀
