I used the collet in the mill spindle. My lathe 3-jaw is awful, like 5 or 10 thou on most things so anything I care about goes in the 4 jaw or a collect but even the collect chuck is something I rigged up so I think its 1 thou runout.....hence the mill.

I don't thing the stem is straight on even the new valve I grabbed....I think I'm going to setup something with v blocks or make something to check them and go from there. I didn't find ferrari specs for this but some motorcylce specs I found are .0020 on the stem and .0012 on the valve head but I'll maybe do a little more digging. I guess if the stem spec is .002 then just a flat plate and a 001 feller gauge would do it for a good/bad check but an indicator is a lot nicer.

I recall you once mentioning that the bearings in your lathe were shot. Did you ever rebuild it?

You should be able to see everything with out logging in...I unless I have a setting buggered somewhere. Yes, there are bots on almost non-stop but usually only 1 or 2 at a time. The high view count was at 200ish I think from like 2 or 3 years ago when I got it running and R&T posted on it. Nothing I know of has happened recently...unless it just people are stuck home and willing to read ANYTHING

Seldom poster but I drop in regularly to see that you are doing okay and that there is a hint of progress.

For those of us who have been here (and there and there) since the beginning you almost feel like family or the guy next door having seen so much of your life.

Keep it up you inspire us less talented tinkerers in the shed.

Stay safe in these very strange times.
