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 been making wheels to create a trolley for the Whippet
Attachment 42791
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?
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.
The final design and installation of the Enjomor Whippet engine on a trolley

What do you think?

I will now run it as installed on the trolley and post the video.
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.Quote:

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...Quote:

We tumble a vibe-bowl full of brass cartridge casings at a time, couldn't be noisier than that.Quote:

sounds like a large workshop, my workshop is just 11' x 7' inside! The tumbler is bolted to the wall - a mistake as it amplifies the vibration, but I have no more room!Quote:

Yes, is somewhat larger...but not more pleasant, inspiring, and often less productive. Certainly not more convenient! It did however cost less than renting equal square footage in Southern California. Result of purchase/ having ownership/ instant equity was just over 6 years at 2005 rates; could easily be 4 or less now. Plus, out of the liberal nonsense.
