Latest engine PMR 3 BI
« on: September 13, 2018, 11:50:08 PM »
Hello folks it had been a while since i posted here. I purchased  this kit at cabin fever. I decided over the memorial day weekend it would be a good time to assemble it. I did it Sunday evening. The only problem is the 5-40 lock nut was missing. I assembled it anyway and it started on the first try. Last Saturday morning i went to the hardware store in attempt to purchase one. no joy . So came home and made one.

I have not had a lot of time to machine lately . Mostly work and time spent in addictive Hobby manufacturing.

They are !! This one i hope to find the Time to make a Lucite cylinder for it that way people at the shows can see the valve action.

The base is a piece of scrap pine from the table project . I just scored the boards in with a plastic cutting tool and a straight t edge

It looks good! Any chance of a video or something that shows scale?

Love the base, nice job, and that is a nice engine (the PMR #3was my first foray into this hobby).

Lucite cylinder sounds interesting, but the parts are awfully small and I wonder how easy it would be to see the motion.  Not quite as simple as the lucite covers we see on the engines with a steam chest, either.  Post some pictures if you give it a try!

Yeah, ok if you square up the side so there's not so much distortion, it would probably look pretty good.  And use clean oil.  :thinking: :)

Sorry Tin. Actually the dime looks very real and I was hoping in a way they had come up with a miniature #3 I wasn't aware of yet 😊

I should have mentioned this engine was cast in that new high shrinkage alloy.  ;)
