It looks distinctly different to not be confused with Munchaster's original engine. I am guessing that is a 150mm long engine with 100mm flywheels.

Pleased to see you are beginning to use metric measurements  :ThumbsUp:

Bed plate is 150mm long but the flywheels are 76mm Stuart 10 series ones. 75mm would have been more in keeping with metric but I wanted to keep as much weight in the flywheels as possible.

Don't know what you mean "beginning" to use metric, this is the 5th in the "series 24" and all have been drawn and made in proper metric not imperial sizes expressed in metric, 4 aero engines also in metric.

 :headscratch: Does this mean you do all your redrawn engines with 24mm bores?


The original Munchaster engine is 8" long with 4" flywheels and 1" bore. Maybe you have mounted the crank in a different position on the base plate on your model as on the original the flywheels end level with the end of the curve on the base plate  :noidea:

No I have done them with 35mm, 16.3, 12, 22 and a few more that I can't be bothered to look up.

As I said before this engine was inspired by the one in the photos and is not meant to be an exact replica and I did not even know it was a Muncaster design until you mentioned it, the Cylinders are more like the ones I linked to that were on e-bay so it's not a redrawn engine as I have never seen the original drawings.

All the ones I have done with a 24mm bore - Jowitt, Muncaster, Thompstone, CHUKY and this Oscillator. There are a few more part drawn up that will also have the same bore ;)

Excellent  :praise2:  :praise2: I have only just caught up with this thread and it's a runner  ::) I like your technique for keeping the pivots inline and true  :ThumbsUp:  :wine1:

Are they a set of plans that you are intending to draw up for all comers to have a go at ?  Something the Stews 'Potty' series ?

Yes Similar sort of thing, Jowitt and CHUKY drawings can be downloaded with links in the build thread and I'll probably do the same with this oscillator. Muncaster and Thompstone will go into ME mag and have drawings there.

Sounds like an attractive series of relatively simple engines for beginners and people with limited tooling  :)

Lovely engine, and expertly built.

There's something very pleasing about oscillators, especially the chunkier ones like this.

Thanks also for all your support and advice on my boiler build - much appreciated.
