PM Research Oscillating Engine
« on: September 06, 2014, 07:52:10 AM »
This is a rather simple engine from PM Research.  I felt the need for something not too complicated as that suits my abilities.  The kit castings are all aluminum and nicely made.  A few modifications were made along the way but it is dimensionally as drawn.  My changes were all in the appearance and just done to fit my taste.  PMR supplies slotted head screws for most of the fasteners and that just doesn't look right.  I substituted brass nuts and made the bolts, removed the ribs cast on the outside of the cylinder and a few other tiny changes.  All the bright work is nickel plated.
Construction is very basic so no photos...
It runs reasonably well with the small and light flywheel-

Nice  :ThumbsUp:

It made a great improvement fitting studs and nuts, instead of using the original screws  ;D

Definitely looks better with real lagging rather than the cast fake.  :ThumbsUp:

Thanks, Gary.  Just can't leave things the way they  come, gotta make it to suit the builder.
