AndyB:
Oh well,

Another day, another f*** up! :(

Snapped a 5BA tap off in the cylinder! :bang:

Fixed it though by breaking up the bits of tap in the hole, extending the hole with an end mill, then turning a plug to fit. :ddb:

Got a replacement plug tap. Funny...not really plug taps are they? Got one now though by grinding the snapped one off flat :nrocks:

Got fed up of putting down Allen keys then having to sort through them all to find the right one... :proj:

Old computer hard drives have great magnets that just happen to screw onto a convenient bit of workshop :clap:

This means it took me all day to complete one little threading job :( :( But that is the fun of it. Sense of achievement riding high again :lol:

Stilldrillin:
Good to hear you finished the day on a high Andy! :D

Talking about holes in cylinders. Watch where this water pipe hole is situated.......

Not my work, and the flywheel o/d is only roughed. BUT........

I guess there's some re positioning to be done here! :bang: :bang:

David D.

AndyB:
Thank you chaps.

BK; I forgot to thank you for the photo; it helps a great deal :bow:

David; a great many thanks for the heads up on the water outlet; I hadn't considered that yet but, knowing my luck, would do exactly the same! :(

This seems to be a popular engine engine to build judging by the number of people offering help and advice with photos...and I have to say :worthless:

Andy

PS. Don't know how much I will get done today as Her Ladyship wants to go to Eye Show (near Diss)

AndyB:
Been doing little bits, but got caught up with a :proj:

Some of you may have realised that I am daft about Drummond lathes although I am not sniffy about the Myford built M types after 1942.

Well, I found a long bed Myford M with the electric drive. It has had a hard but not very productive life; the back gear has been removed after whatever happened to knock a load of teeth off the bull wheel and small engagement gear (don't know what that one is called). The half nut has been attacked by whatever has been dragged along the leadscrew, but the leadscrew is almost perfect! Bed is great condition.

My hoard of bits has come into play (despite all SWMBO's comments to the contrary) and I have ended up with an almost brand new condition lathe...my 9th :doh:

I have done some more on the engine though.

The needle roller bearings for the flywheel bracket fir perfectly after my repair...

The walking arm bearings are in place, just need boring...

The power piston is on its way to being a fit in the liner, but I am taking that very slowly ::)

I have found an ideal bearing plate to mount the flywheel onto the face plate; an old Harley Davidson clutch plate! :smart: (from another box of bits that she said I ought to chuck out :lol:) It has holes already drilled in just the right places :). I have used a friction plate so it will prevent slip against the aluminium...remembering the problems I had with the cylinder :lol:

Jasonb:
Thought it was you who posted the flywheel pic on ME, comming along nicely
