Kerzel Hit and Miss

And now the gas tank. I cut a length of 1" copper pipe and faced off both ends. I did not have any large enough round stock so I had to make the ends of the tank out of 1/4" by 1 1/2" rectangular bar. I turned a small boss that fits inside the pipe.


Then soldered on the end cap, trimmed off the corners with a hack saw, and mounted in the lathe.


I turned down the brass ends and used some 400 grit sandpaper to clean up the ends and polish the copper.


Here is the tank and the mounts. I still need to make the filler and outlet ports.

Fuel Tank looks good. Am glad the copper pipe survived the drilling. Please advise drilling process.

Gus, I always hold the pipe in my milling vice on the ends, I can get a 6"opening, I then drill a pilot hole and follow with a milling cutter.

Hi Paul,

Your method is best and risk/fool proof. I took the risk drilling on the drill press but drill was regrind for brass and copper(hopefully) and got away when drill broke through w/o snatching.Holding the copper pipe lengthwise in the vice was not best idea too. Neither was vice clamped to drill press.
May not this lucky for next job.

After about 220 hours of work over the past 11 months, I have completed my build of Kerzel's Hit and Miss. This was my first IC engine and I am very pleased with how it turned out.

Runs and looks great, slows to a stop nicely when the spark removed.
