Despite a weekend trip to NYC the weekend after and leaving for a cruise at the end of the month, I have booked a trip for this weekend as well. Staying Saturday night at the Hyatt Place in Ft. Wayne where I stayed one night a couple of years ago. Too late for minor league baseball in Ft...

Back in the far past I had a "carbide cannon" toy that would make a loud bang when the gas produced by some wet powder was ignited by a spark. In the army when on the rifle team, we used carbide lamps to darken our sights with the smoke.

Parts that are profiled and do not require milling on both sides of the stock can be separated by the width of the profiling tool and be retained by stock at the bottom, which is then milled off in a separate op. Alternatively the stock is glued to a fixture block and separated later. Or if...

I have a '62 BP and keep the belt on the middle of the pulley. I've never needed to move it in 16 years. It's fine to overspeed these motors for short periods of time. For slower speeds needing torque I use back gear and reverse. I removed the power switch and control the...

The jig for sawing the round bar lengthwise is something worth remembering. 👍

Interesting variation on the reversing shaft. Well done.

I have a 4" Kurt vise (actually 2) that I'll sell for $200 each plus shipping. Used and could used a cleanup, but no holes drilled into them. Comes with regular steel hard jaws and a pair of aluminum soft jaws.

Usually those once-in-a-lifetime events happen more than once, so it's a good thing to get rid of those tree limbs now.

Now that all the motion parts are complete you can check the timing and adjust the valve movement. Looks like the hole in the side of the base to anchor the bottom of the reversing mechanism is still TBD.

FWIW, I used Loctite for the rods while the rockers were aligned on a surface plate. You could pin them afterwards, but really not needed.

If the piece was completely into the collet the "belt" would help resist bending.

If you like I can reference part dimensions on my engine; I assume they would scale.

My engine runs very well without rings and with less accuracy in diameter. Your fabrication method is cool.
