Hello Hugh,
The lever handles are about 12mmx1.75 tapped and the pf grip is ~10mmx1.5 as a stud ( on mine it is a perfect fit for a 3/8ths- 16 stainless steel bolt.) I say "about," because I have found LaPav to be a bit over or under sized in their threading. You could cut the head off a 3 or 4 inch bolt from the hardware if you wanted and then epoxy the shank end into the wood giving strength through the whole length.. Old hardware stores and auto parts stores are wonderful for finding odd stuff and metric stuff!! J-B weld is the great answer to metal to wood. Clean the wood and metal well first with alcohol or better yet, M.E.K. to remove oils.. The Lever handle could be made the same way using a piece of 9/16ths round brass or bar from the Hardware store. The taps and dies are about $15-$20 and the brass or pipe would be what you can get locally. Or PM me and I can make and send you a core for each.
The Boiler cap knob presents a problem. You could have someone use a lathe to cut off and drill and tap the existing knob, It may be of Bakelite with brass inside or may be all Bakelite. For the steam tap the pin is through the shaft and must be pressed out one side, that makes the steam tap the simpler project.
I use Mahoney's Walnut oil and beeswax for a finish. They are food safe and, if the owner takes care of salad oiling them, they are holding up well. You might look at the "Rebuilding the Oly Twins" site for some other ideas as to shape.
HEREThere are a few hints as how to proceed on page six.

I've always wanted to do it and have decided to finally do it after looking at srobinson's amazing photos of his wooden handles on his cremina. If anyone has done this for their Pavoni I'd love advice. I got a nice piece of cocobolo today. I figure the handles will be fairly easy, but I'm not sure how to make a knob for the water tank that will screw in perfectly, and I'm not sure how the pin attaches the steam release knob to the pavoni - is it threaded or does is just slide in snugly? If I can't make the knobs work that is fine, I'll still be happy with the handles, but I'd love to replace all 4 pieces.
Also any advice on how to treat the wood is welcome, too - linseed oil, wax, naked?
(Yes I know that I could order them pre-made, but I think it will be fun and cheaper to make them myself).
