Congratulations on getting the surprise of having an unexpected and pleasant run!!

Very interesting valving mechanism on that engine as it is actually set up like an oscillator, but has a moving valve plate that essentially does the oscillating allowing the cylinder to remain more or less stationary ..... cool!!!

It turned out out be a screw, or maybe someone previously tapped it. I have it running now and it runs lovely, the video is on Youtube. Thanks for the help guys.

A link to that video would be very helpful if you would care to provide it?!?!

Post by: komet163b on May 31, 2026, 03:30:39 pm: 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

Post by: Anotherhobby on May 30, 2026, 02:33:19 pm: 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.
