Title: Latest engine PMR 3 BI
Post by: Tin Falcon 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.

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

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!

Post by: b.lindsey on September 29, 2018, 10:54:26 PM: ??? That must be a big dime as the #3 isn't that small.

Post by: b.lindsey on September 29, 2018, 11:24:10 PM: 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 😊

But assumptions are always a trap as we all know.

A nice looking model none the less.
