Hi All
Well I've done most of the grubby bits on the collection of disparate parts that I hope will turn into a a 6/1 and I've 'dry fitted' them back together, as a practice run (and to stop me loosing them)!
I'm now waiting for a mate to bring the bits down to try and sort out the crank and the head.
A couple of questions,
What is the thread for the grease nipple in the rocker shaft? I've tried with the bits and pieces I have up here but can't match it.
The dipper it came with is home made,but longer than than the 'Indian dipper' I've acquired - (the Indian has a different thread from the 3/8" Whitworth in the con rod) so today I made a 'hollow dipper' - mostly 'cos it was raining and I was bored! - I have what appears to be a 1933 bottom end, with a 2 1/2" big end, plain main bearings and a splash plate. Do I use the hollow dipper or knock up a solid one? There seems to be a lot of conflicting advice on the site and I'd welcome everyone's opinion
Finally, the piston is an iron 4 1/2", with provision for four plain rings and no oil control ring. The bottom housing is machined in a similar fashion to an oil control ring, with ports bored through to return the oil through the body of the piston. It has a little corrosion damage but looks like it has never worked hard and as the rings gap at 15 thou top and bottom it'll be going back in regardless of it's heritage!!
Thanks in advance
