| PeterE:
Thanks Jim and Don! For me every step is tricky as this is the first engine build ever for me. BR /Peter |

Well done - I'll use that method now! :lol: |

Hi Well Done, Like the method. Cheers David |
| PeterE:
Thanks a lot! Cannot claim any originality about the method since I read it somewhere, but it felt as it would be the right method for me - and it was. Anyway, managed to get two thirds way through another fiddly little piece today, the gland nut for the piston rod in the lower cover. After turning a piece of brass and threading it 1/4"x40 it needed six small slots around its circumference. 2 mm wide slots, hmmmm, time for the small FC3 cutter again. I set it up in the mill using my six-sided collet adapter to mill the small slots axially. (I missed making the rod long enough to allow machining square to the axis :palm: ) Here it is ready for milling. There is not much clearance as the mill is very short. It worked out fine and no broken mill this time - phuhhh. The little nut parted off and will be faced off to size and properly finished as soon as I have a suitable mandrel. Next up is the piston (CI), piston rod (BMS) and guide part to which the crank attaches (brass), but that is for another day. BR /Peter |
