Model Engine Review - Enjomor Whippet

[editor@glue-it.com]

This is a model engine that I've been sent to have a look at, review and have a play with. First of all I'm unpacking and having a look at it:

and a bit more of a look around the engine, exhaust, carburetor and coolant connections

Unpacking the Enjomor Whippet

A peek inside this Enjomor Whippet engine is quite interesting

I needed a cooling water tank, trouble was the larger tins had the right look and the smaller tins were the right diameter....

Someone commented that this doesn't fit the aesthetics of the normal models I make, I think he has a point....

Finally running the engine, initially on glow fuel.

Credit to the design of E.T. Westbury for how easy this is to start and how well the Whippet runs.

I've just briefly written up the process I followed for making these wheels, the most important step was making a mandrel so that I could easily and repeatable mount each wheel to the lathe and then the milling machine.

I've been making wheels to create a trolley for the Whippet



Made from 1/4" thick mild steel. Hopefully they look like an old cast wheel that you might find on a stationary engine trolley - thoughts?

The texture of casting might be imparted by etching or shot blasting. Blast might edge out for appearance, it'll blend every tool mark evenly. There might be a way to texture paint or add a 'contaminant' instead. But they are beautiful raw.
When I needed a super finish on narrow surfaces, the trick was stoning one flute off a two flute end mill, making it a fly cutter, but makes clean corners tedious.

thanks, I did tumble them in ceramic beads for a few hours, but this probably needed to run for hours and I got fed up of the noise in the workshop...

The modified two flute mill is a good tip, will have a go, Thanks, Nigel
