Viceroy surfacing gears problem

Bush them. Personally I'd use bronze.

The surfacing is now "sorted" for the present.

I turned up a bar to 9/16ths to be a push fit in the smaller spindle bore. I bored out 2 12mm washers to 5/8". I passed a piece of 5/8 silver steel through the elliptical 5/8" bore slipping on the washers to locate on the outside and inside face. Clamped the 9/16" bar down flat on a surface plate with the 5/8" alongside it, clamped the two bars together with a correct spacer between to give the required 1.250" centres. Both bars are now true and parallel to each other. I then glued the washers to the yoke faces. (5/8" bar was sprayed with mould release first). Once cyanoacrylate had gone off I removed the 9/16" bar and fitted the yoke to the four jaw. I then set up by clocking on the 5/8" bar, at the yoke and about 6" away. Once trued and tightened I removed the bar and heated the washers and removed. Bored out to 3/4". Turned and tapped a mandrel in the 3 jaw. Fitted and turned two "Oilite" bushes to match bores produced. Tapped bushes into yoke with the 5/8" bar in position to give alignment. Lovely fit and no need to ream. Reassembled yoke with the worm back to front from original. Worn worm face now runs on unworn wheel tooth face and vice-versa. Reassembled to apron and it works a dream. will probably see me out but I will keep an eye on it. All in all "A good day"! Only bad news was I dropped my Arkansas stone and broke an inch off the end. I knew I should never have got rid of the carpet in the garage!
