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.

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

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?!?!

Well now, that was enjoyable!

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!!!

Thank you for that wonderful video I especially like that very unique valve system on that engine Don't hesitate to make more videos we're all here as steam enthusiasts and would definitely enjoy more!!!
