Cox cylinder/head tap
Has anyone here ever had or heard of a tap for the 17/32-40 thread in the crankase and cylinder for Cox .049? I'm tinkering with the possibility of some engine projects and figured this to be the most difficult part. Here is a picture of one I made but it is of leaded steel and I'm not so sure it will work properly. I have considered single point threading the cases as well, but that seems very tedious so I figured I would see if any of the halfers here had any ideas. Thanks in advance, Todd
