Had another session on my vertical cross engine yesterday… machined up some small bits from brass…

#53… top cover
#59… Stem nut
#60… pipe flange
#65… pipe connector

​Those who have made one will see from their dwgs… still need to finish of drilling etc.

p.s what method did you use to create the effect, small wire brush, rolled emery cloth, abrasive pad?. I have used various methods to varying effect, just a point of interest.

Hi George

First off I bought a very low grade drill press off e-bay for £20 specifically for this job and with the intention of selling it again after I'd used it (although I'll probably keep it because after a bit of fettling it's OK for butchering the brown stuff).

Then I made an abrasive tool from a piece steel rod, a piece of 20mm dowel and a pad of soft leather cut from one of Mrs Jim's unused belts (I think it was unused, it will be now!)

After some experiments with fine and coarse valve grinding paste I settled on the fine and, after clamping a fence to the drill table, away I went.

Made some more bits for my vert. cross engine…

Valve body, spindle, still need to thread spindle to mate up with stem nut, drill bottom flange.

​Partially assembled valve configuration …
