:offtopic:sorry to go of topic a little David, but nick mentioned lapping with toothpaste, would smokers tooth powder be any good as its a fine abrasive ? and its a pretty pink colour so you could try getting the missus to do it for you,haha. ...mike... |

Thanks for your replies Chaps! Much appreciated...... :thumbup: Nick. I never thought of raiding the bathroom! Or trying scouring powder.... ::) Mike. Smokers Toothpowder? I think Colgate Sensitive is more me! Got a little more done. Drilled the deck, and opened up to 18mm....... The new boring head had arrived. So, reset and clocked true........ And bored out to 18.5mm....... The whole clocking/ boring operation took around 20 mins. This is the first time ever, I've used a boring head. Despite first using a milling m/c in 1958! I wonder if I'll ever use it again? Something special... Awaiting a something special job...... Shortened the cylinder tube to, stroke + piston length. Then turned spigot to -2 thou on hole size....... Nothing is finished, yet. I'm not sure about the steel discs. Might try protecting the balsa with cooking foil..... Time to start cogitating on the crank assembly...... Can't get me head away from a Ross yoke. But, I don't understand the calculations. :bang: David D |
