Very interesting reading through this Ross.
It's easy to forget the amount of things that just "don't go right" when you first get your machine/s. :doh:
We've all had and still often do have those arrrggg! moments where it takes a great deal of self control not to throw your work at the nearest wall! :bang:
Glad you persevered and obtained the good results :thumbup:
Looking forward to the "it's running" post.... but not as much as you are eh? :)
On the taps and die front.... Are you using split dies or die nuts? Makes quite a difference.
Just to add my 2p worth.... I always undersize a part to be threaded "male" and oversize a part to be threaded female.
It depends on thread dia and pitch as to just how much it really makes a difference. My torches M12x1.5 are quite forgiving. model size stuff I make using M2 threads are not! Time and experiences (stressful as they are) will let you know where the detail is required :thumbup:
Ralph.

Hi Ralph,
Ive got a mixture of split and nut type dies, the smaller ones are split type.
I'm getting there with the threading I think, it's all trial and error.

Hi everyone.
Today I put the final pieces together for this engine,
I marked out the holes on the base and the engine post.
I then drilled and tapped the holes in the post to M6 I drilled the hole for the crankshaft too.
And drilled the holes in the base with sunk holes for the bolt heads.
Next I assembled the base and post.
And finally I assembled the other bits and bobs. Just the flywheel ad pipe work to do now!
I tried machining the recess on the flywheel with no luck. The tool rubs alot has anyone got any further tips on this?
