Bearings installed in the firebox



axle was very true




brass inserts made for the bearings




2k watt voltage reducer installed in base





base tidied up



a Wilesco valve (from a converted whistle) installed in the steam line & a pivot pin (functioning) oiler installed in the steam chest




A brass end cap fabricated with set screw to ensure straight running of the axle/flywheel (to keep them distanced properly)There is a lot of lateral movement (slop) built into this inexpensive plant which allows the axle to wonder ,its important for the axle to be stable in its location to keep the piston connecting rod centered as much as possible for smooth operation.




running it in now...went from 6psi stall to 2.5 psi stall speed , probably as good as I'm going to get for a single oscillator. I'm waiting on one more item to come through the mail (might be awhile) the way USPS is functioning these days.
