NickG:
Right, had a mixed night tonight!

Started on the flywheel .. .still on track to complete tomorrow night, not worked out how I'm going to fix flywheel onto shaft yet as I've found some little alen key grub screws but I don't know what thread ... don't think they're ba and I don't have any other taps that small. On my other engines I've always had a screw sticking out but it looks a bit messy.

Anyway, started by sawing through the 2" steel with a hacksaw. That took 15 minutes, was pretty hard work but quite impressed as I got the cut fairly straight for once :lol:

Facing it to true it up

Finished flywheel blank

Turning recess ... at first I had a smaller tool, then changed to this as it has 2 cutting edges so thought I could save time just swinging it around, however, it was too big, so had to go with individual left and right handed cutting tools.

Note, by this point I had already drilled the hole and done a trial fit on the crankshaft ... it was very tight and managed to get it stuck. I was turning it to get it off with my hands and slipped. The sharp edge of the wheel scratched my thumb ... or I thought it had, then 30 seconds later I looked down and saw it was covered in blood, sort of pulsating with splashes on the floor. One of those where you don't realise, then when you see it get quite a shock! Think it's going to be sore tomorrow. I tried to take a picture of it but it doesn't look much, the plaster has pulled it together quite well, think it's going to scar though.

Anyway, soldiered on to get the recess done on 1 side but I was trying to de-burr it with a needle file and one of the chuck jaws caught the file, could have pushed it straight through my hand, I was lucky ... don't actually know what I was thinking really. At that point I just stopped and came in. All the machinery and I go and lacerate my thumb on a burr. It just shows how many hazards there are in a workshop.

I need a :wack:, safety is drilled into us so much at work this sort of thing shouldn't happen to me.

Trial fit on the engine:

I actually quite like the look of it without the holes but still think I'll put them in. Also unsure whether to paint the inner bits red, that has become a bit of a trade mark of mine!!

Nearly there!

Just take care Nick you did the right thing and quitting for the night you may have bin on the tired side.

Engine coming along great, have you thought of supper glue or loctite for fixing the fly wheel thats what I've used.
