Next up, the base. I just cleaned up the surfaces.

Then I eyeballed the best position for the frame mounting screws. Then scribing with my calipers (2.90 inches), I transferred the hole position from the frame to the base.

Timing Ports:

This part is critical and I have only one chance of getting it right.

First of all: DO NOT FOLLOW THE PRINTS!!!!

Do it to what you have.

So I created a scribe out of a small piece of brass. I then inserted the scribe into the cylinder ports. After that assemble the engine and slowly turn the engine scribing the port travel on into the frame.

This is where you should not machine. The machining should be to the areas that are not scribed, with a bit of overlap onto the scribes.

I hope the pictures show what's going on. If you don't get it, please ask.

Now onto a preliminary video.

As expected, the engine leaks, knocks, etc. and the video shows that. After some adjustment and breaking in the engine ran much better and I got the flywheel oscillation out.

Pressure is about 10-15 psi here in the video. Later on, I got it down to about 7 psi.

Onto painting, but that's another day...

Nice job machining this model. Thank you for deciding to continue showing your machining setups. I need to get started on my kit soon. I'm 67 years old and have too many projects and not enough time to get them all done.

Next up...

In preparation for painted, I used a Dremel tool with the rotary burr to remove the casting flash. I did this while the engine was assembled so I only removed the flash where it was noticeable. Also, I'm not some nut about perfect blending and smooth surfaces.

After all, 150 years ago they didn't do it, so why now?

Thanks Matt, but it's not yet done.

Today I disassembled and prepped for painting. It'll probably get a coat next weekend then my wife can put on embellishments.

Then it'll turn into the mantle dust collector it was destined to be.

...Ved.

Default Myers engine machining pics

Absolutely loved your Myers Oscilating engine Machining pics. Don't be discourage by a sour grape or two, appreciate you posting the pics and comments. I have been considering purchase of that kit but will probably avoid as I only have a 10" swing lathe. Keep up the great work!
