EDIT: just to add, the only thing I would say is that when I fitted the crank between the bearings it is a super tight fit and I`m going to have to turn a bit of the end of the bearings. Everything is to size, the bearings are not too long and the crank webs are not too wide so following the plans, I`m not sure why this has happened. I`ve about .5mm gap between the end of each bearing and the crank web. Chris |

I always ream under power, I've never had particularly good results with hand reaming. I just put the machine on slow and 'run it through'. The type of reamer doesn't matter that much, the main difference between hand and machine reamers is just the taper at the start. More often than not you've just drilled the hole and swapping the drill for the reamer is the 'natural' way to do it. (Usual disclaimer of incompetence/ignorance applies here). As for reaming in situ. There really shouldn't be much 'effort' required to ream the holes, if there is you've probably drilled them too much undersize. Regards the 7ba bolts, lets hope they're not as flaky as you think! Having the bearings a good fit in the soleplate is what makes the bearings 'strong' the bolts are just there to stop them lifting. If you think about it when the engine is running, it'll be nodding along at a decent RPM, the crankshaft is unbalanced and there's a fair bit of hammering from the piston, compared to that the reamer is just tickling it with a feather.... |

Glad you said that as I have used a reamer under power, as you suggested, progressing from drill to the final ream. I just thought the hole was a bit big for reaming under power when I didn`t know if it should be! Cheers for the advice. Chris |

Hi Ray, thanks for looking. Yes, I`ve just had a few weeks break on this build as I was making a few puzzles as shown in one of the other project logs. However, coincidentally, I started work on this again tonight so will be posting more pics soon! Chris |
