I'm still trying to master crown moldings.

Good subject, and something I've struggled with for years. Recently I made a fixture to mount the tube to my rotary table. A bi-metal hole saw mounted in the mill-drill does the cutting.



I  bought a cad program to help design my frame. (I've always been a "Hume Cad" kind of guy myself, but am being won over by this technology now.  :evil: ) If anyone is interested the program I'm using is Alibre Design and is pretty easy to learn. Once the tube is designed the program lets me find the angles and offsets that I need to cut the tubes.

I found the real benefit to this in the downtubes on the frame I'm building now. The joint at the neck is off center on each side and they meet the lower tubes at an angle. With this set up and an electronic protractor mounted perpendicular to the tube centerline for rotational angle reference I was able to cut them to fit properly in just a few minutes on the first try, with no scrapped parts or hand fitment required.



It worked out really well for me and save a lot of time. I am able to get precision offsets and angles with the calibrations on the mill table and the rotary table. The electronic protractor on the tube requires a little finesse to get the tube clamped in the fixture in the proper position but isn't too bad.

I haven't been able to find anything on the market that is affordable to the home builder to do this kind of tube notching, so maybe this will help someone.

BAILEIGH, if your company comes out with a similar set up after seeing this, I expect a royalty, or at least a complimentary sample  :evil: , and a donation to SSS for the site.  :cheers:

Neat program on laying out pipe notching pattern. Do you have something similar for figuring out the before notched tube length?
Thanks

If you have a steady base like a mill or can jig up to a mag-drill I like to use a Rotabroach personally.
Much like a mill cutter but with the center missing. Makes a very clean round cut in tube or plate.

Does anyone make "fine" tooth bimetalic hole saws?

  We used a holesaw on a drill press . Worked well for our purposes and was cheap! You can see the quality of the fit in the picture below.

 after cutting a basic size / length / angle with a common endmill in the milling machine,
I have been using a cheapie vertical ocillating sander that uses a tubular roll originally made for wood working..
    ...... been doing it this way for many years to maker the final fit just right.

Hi Mike...
  I have a variable speed press, so I cant tell you the RPM's exactly, but it is cut at a very slow speed. I'm guessing about 100 RPM or so

Thanks Baileigh Inc. Just purchased the Bend-Tech Pro. Now I guess it's time for some serious reading and hopefully learning.
