First Run of the Lister D Working Miniature Gas Petrol Engine from Jin at OKMO and put out by Retrol and sourced from EngineDiyShop.
1926 - 2026 Anniversary - The Lister-D
The engine started first go after having oil put in the sump, fuel in the petrol tank and water in the cooling hopper.
Jin at OKMO has done an absolutely incredible job of miniaturising The Lister-D to this scale, the detail is just incredible.
The engine sounds just fantastic purring away and I'm really looking forward to testing out a lot of different accessories after a few break in runs of the engine to see just what its capable of running.

I don't think it is a screw....just a pin.

I had a #45 whose 'screw' was probably a stickpin
cut to size and set into a hole drilled into the
crank throw.  Still had the head on the pin.

This may be a time try something unusual.  You might
look through the listings at 'Classic Tin Toy co'.
They stock all sorts of old toys/parts, including those
for steam engines and reproductions of original parts
such as the following...
'Weeden Engine Eccentric Crank handle 1/2" reproduction'.
I bought 2 and used one.

Get 'em while you can.  I don't know how long this
company will be around.

Good Luck,
Wayne

Looking forward to you running that beauty in there mate!!!

Hi all, I have come across a tiny Weeden no7 made from 1890-1907. I am really pleased with the condition and it only has 1 screw missing but it's supper tiny. I'll add a photo, any idea of the size? I'm going to measure a piece of wire tomorrow but I thought someone may know tiny sizes better then I do.

An impressive bit of work you have accomplished so far. Seems most of the hardest work that requires the greatest precision may be behind you, but details remain! That it all moves so freely, and coasts so well, speaks volumes about the precision you have achieved thus far!
