j45on stole my thunder so to speak, posted as i was looking for

machineshed:
if you are going to lap things, i think it should work :thumbup:

NickG:
Looks good, the only problem with that one on youtube seems to be the flywheel is too light.

Raggle:
I wonder if embedding metal inserts is feasible, as in the case of injection moulding? In the case of a flywheel it could be made of lead at a predestined pause in the printing, for instance a half depth cavity then place the insert, then a finish to completely enclose the lead.

That could possibly work for bushings at conrod ends, allowing for reaming in situ.

As usual, I may be talking rubbish, but Chris was doubtful about a wobbler at the beginning of his thread so I maybe in good company

John Stevenson:
How did the bearing come out Chris ?

The UP ones seems to print a disposable support, does the reprap ?
