I have a set of valves with some markings on the tips from the lash caps they had on them, they need the tips facing and I will have a CBR head next week that the valves have the pips from the buckets and I usually shorten a few valves to clearance them.
I usually trim the tip's by hand on the side of a wheel, but I have a grinder which would have come with an attachment for the job so I bodged a gizmo to grind the stems, been going to do it for, well since I got the grinder in the 80's.
I have done a similar thing before, made a cobbledevice to face rockers. I used the same cup stone as far as I know, but it didn't have any chips and ran true[much better finish] I will have to run a diamond across it; it hadn't fallen on the floor and been kicked behind the shelves[ I ran it for a few minutes to see if it was going to go bang]. I took just under 2 thou off that valve, I took it off in a three goes, I turned the valve though 120 degrees and had another bite each time to see it was taking it off square, amazingly it is.
No welding in it but I did braze a scrap of 25x3 flat to that scrap of 1-1/4 tube.
