Building stop to check TDC
Here is how I made one without welding. You will need a compression tester adapter (a spark plug non-fouler works too) and a screw and some nuts.

You can add or remove nuts till you get it the right length.
I think the screw is a 10-32 about 2" long, though longer would be a bit easier.
This is what it looks like when done
Just make sure the nut you put on the inside is tight. I used this when building my slant and it worked good.
