Made a start on the pistons over the last couple of days. The first thing I did was to hone the cylinders sp that I would have a final size to work with, I used a flexie hone with plenty of oil, I didn't go over board with the honing just a quick lick up and down for about 10 seconds, but it was enough to produce a nice smooth bore. Then used this new toy to give the cylinders a good clean, its a lidle ultrasonic cleaner on offer for £20:- Great for cleaning glasses and false teeth, wanted to try it out on Mother in-laws teeth, but the miserable old bugger wouldn't let me. Then I carefully measure the bores they were all within 0.02 mm and kept a not with each one of their size. The turned down a chunk a window sash weight and drilled and bored the ID. Then I wanted to try out my home made tool post grinder to get a nice finish on the OD of the cylinder, it took me a good bit of time and a lot of 13 amp fuzes (don't ask :zap:) to wire up the new toggle switch I'd bought for it. But it worked a treat got a nice finish on the cast iron and a nice fit. This is two ground up and just sitting nicely in the bore, the third is still on the bar waiting to be parted off:- thats a job for another day Have fun Stew |

Stew, Looking great, I bet with that flexi hone and grinder you have got an amazing fit there. Very nice. That ultrasonic cleaner is a bit posh too, did it work well? Nick |
