I recently started a new project. Phillip Duclos's Huff-n-Puff. I wanted to do something a little smaller for a challenge. I had been a little leery to work with the small stuff and after doing a few parts and my highly trained experience of 5 tapped holes of 0-80, I am now enjoying the challenge. with this I also have some questions. When I get to the valve rod cam and the flywheel, It is going to be very close with the tap that I have. The flywheel has a 3/16" thick body and 3/4" dia. The crankshaft diameter is 1/16". It says to use a 0-80 setscrew. I don't yet have a bottoming tap, I have a tap from the local train hobby shop and it is obvious the tapered threads on it are too long. will a bottoming tap have enough room to create a full thread before it goes through the 1/16" hole drilled in the flywheel? If not what do I do here? Hope this is clear as mud.
Here are some pictures of progress so far.
The engine is 1/4" Bore and Stroke.
