does anyone out there know what threads Stanley used for their No. 50 Combination plane. I’ve just bought a second-hand one and it’s had a bit of DIY done to it to replace missing parts. I’d like to make some replacement parts that matched originals.

There are two sizes of threaded holes on my #50 Record combination plane bought in the mid to late 1960s;

1/4 x 28tpi (most likely to be 1/4 UNF) and 3/16 x 28tpi (not a standard thread) but I don't know the thread angles.

Seems odd that they would have used a special thread for something like that. There is 12-28 UNF which has a nominal OD of 0.216" .... actual samples will be smaller.

If you google "Stanley tool screw threads" lots of info comes up.

Regards,

Peter.

Thanks for that info chaps. That Australian thread on Threads was very enlightening. I’ll see if Tracy tools can help out with odd Taps and dies for Stanley planes.

Funnily enough I saw some on EBay a few months ago. Wish I’d bought them now!

I have a Stanley No45 plane. It definitely uses 1/4-28 for some of the threads as I had 1 thumb screw missing and the thread was stripped, Found a screw online and used a 1/4-28 Helicoil to repair the thread. There is also a smaller size used but I never checked the actual thread.

I had a collection of wood working tools including a number of Stanley and Record planes some with the odd screw missing. After some research I found a set of assorted screws and wheels for sale on Amazon. They didn’t all fit my requirements but I was able to complete the missing parts with a little work. I think the thread I wanted was 3/16” BSW or F and the parts were less than a set of taps and die which seem to be in rather short supply.

Hi All,

Stanley were notorious for having all sorts of odd thread sizes on their tools and accessories!

Most of the small plough planes use 3/16BSW for the thumbscrews but you will often find 5/32 and 7/32 as well, sometimes even 9/32 here and there.

I have just had batches of plough plane clamps made for which I am using 3/16W for the new thumbscrews. It really does not matter except to the ultra purist collectors

i am about to order the LH taps and dies for the adjustable spokeshaves and plane adjuster threads, Tracy Tools being the go to guys!

cheers, Martin

I’ve had a lathe for about 12 years and have yet to try this dark art - I think it’s about time I get into single point threading to make my missing parts. Tracy tools appear to have some of the taps but not all. At least it’s not critical parts that need to be made and they are very small so - only some practising time to be spent.
