Hi

Thanks Roger.

I needed a couple of bolts for the eccentric so today I made a couple. Start with 2 studs made from 3/32 stainless steel.



Screw on 2 steel nuts



Silver solder



Clean up





Fitted in the eccentric. I will fit locking half nuts on final assembly



Moving on to the piston. About 6 months ago I bought a piece of cast iron bar to make the piston. Could I find it.  :shrug: :noidea: :thinking: :old: yes after about 2 hours of searching, what a waste of a rare saturday afternoon in the workshop :censored:

The piston rod is 5/32 stainless steel.




The elusive cast iron turned to size and drilled and tapped



The piston rod is held in the tail stock chuck to ensure correct alignment. A drop of loctite on the thread and the 2 parts screwed together.



Cut a ring groove and part off



Face and size the piston





Cheers

Hi

My plan is to get the engine to run on air. Once I know it will run I can can get on with the boiler. I have started to assemble the engine, if it does run I will strip it down again to finish off all the cosmetic bits and polish it.

Here's some of the parts. The cylinder block has had the studs fitted.



The slide valve and the slide valve housing fitted.



The slide valve gland is packed with carbon string.







The cylinder covers, piston and connecting rod in place





Cheers
