I need to run a tap through my Canadian 236 fount to clean up the threads and was curious to know if the Canadian models used metric or standard threads. If anyone knows the correct size & thread pitch, it would be greatly appreciated.
thanks

Try the search function - there are about 100 threads on Fount Threads, appropriate taps etc.

Canada went metric around 1974...so anything before that date IS standard thread. It also took  quite a while for any Canadian tooling to go metric even after that year.

1/2"-32 TAPERED.  Isn't that special?

Thanks for the info. I searched some of the posts and saying the 220 uses 1/2-32 threads. My 236 & 220 look pretty much identical. My 32 tooth pitch gauge fits my 220 nicely but not so nicely on my 236. It's the closest pitch that works and i tried my metric pitch gauges as well. So that must be it. I'm still puzzled by the 1/2" size though, because 1/2" is much bigger than that, but I'll give it a shot. Thanks!

Sitting behind me is a 220C head on a 237 fount (same threads as 236).

it's a proprietary thread made by Coleman for Coleman. You aren't going to find it at the hardware store. There's a number of odd screw and pipe threads Coleman liked. Probably for a reason. Maybe they envisioned "steampunk".

I picked up the 1/2"-32 tap on Amazon, and that is the one and it did the job.  thanks!

the 1/2-32 you picked up is a straight thread. the Coleman thread is a tapered pipe thread. Good that it worked for you but there is a difference.

Yeah, The correct tap is 1/2-32 tapered like a 1/8-27 NPT tap. You can only get those for several hundred $$...

Tried Victor Mach?  victornet.com - they have a custom tools group.

When I  ordered it, it said tapered. When I got it, it was labeled tapered, but it wasn't tapered. It did what I needed it to do though since I only need it to clean up the first 3 threads.

A well-chosen sealant would also help if you had to go deeper than three threads.
