Travis Steam Engine #4

[jjr2001]

I wanted to build a twin piston steamer and found the plans for the Travis #4 on line with a many more on his site. I cut the head, flywheel, and frame pieces on the CNC router and the rest of the parts are manually produced. I also wanted to build one without using castings.
The aluminum flywheel has been filled with lead. Only weighs in at 8 ounces.

Here are a few pics of the parts so far:

nice looking work what type of cnc router do you have? also I notice the kant twist clamp made of brass? in your avatar. do you have any more photos of those by chance

Thanks for checkin in.

The CNC router is home brew. My design from builds that I viewed on the net. I picked the elements that worked for me with only wood shop equipment (at the time of build) and bought most of what I needed on line. I think it goes beyond a CNC router..I call it my Flat Bed CNC Mill.
Here is a build thread for the CNC:

The brass Kantwist is also home brew. Used pictures and drawings found on the net and made this one that is between two sizes of actual Kantwist clamps for an intermediate size.

That's a nice cnc router you have. you are very talented.

Thank You. I built the CNC to make parts for my model airplane habit. While I did make a few planes with it (F4 Phantom2 for one) the CNC was so much fun building that I thought I would rather build tools and models of metal. So I ended up with the mini mill and mini lathe. I don't fly model planes now, just make things in the shop. The CNC has capabilities way beyond cutting 12x24" sheets of 1/8 plywood so I just use it for cutting out parts for the shop making pallets (milling), or even flywheels and other crankshaft parts.

Cheers, JR

Completed the Travis Steam Engine #4 today. Gave it a few test runs on the bench and it runs great.
Here are the final pics:
