well....Is messy alright, you need a strong vacuum a mask and gloves. Don't breath that stuff is nasty. I would suggest enclose the CNC in a acrylic box, so to contain the dust. It blunts tools in a hurry. Some tools are better than others but on average have a big supply. I don't have a CNC or a milling machine I do everything by hand, and let me tell you that I buy the drill bits by the box. I keep all the old ones and I will re-sharpen them. (someday) But I'm having and you will too. Bill
And a great filter on the vacuum I imagine! I've read that some people do manual cutting with water running over the part to collect the dust, so it never becomes airborne in the first place. I'm going to have to experiment with this tonight, I need to make an adapter plate to mount the gimbal to my airframe, and I'm not comfortable printing that. I'm not as worried about the holes I need to drill as I am about the cuts I need to make. Steve
Thanks, Bill. I hope the word you left out of the last line (inadvertently, I'm sure) is the word "fun" and not "conniption fits." So you use a vacuum bed to hold the part down and the usually approach to tool direction.... What kind of cutters do you like to use? If you have any part numbers or favorite suppliers, I'd much appreciate knowing....I typically would get them from McMaster, but I've not tried cutting anything harder than wood -- so my CNC is already in a big box with dust extraction.

Stevegalle welcome to the forum. Would you be kind enough to change your user name to your real first name and last name, please? The reasons for this (and how to do do it) are explained here: http://forum.freeflysystems.com/index.php?threads/real-names.497/.
hello bill what is wrong with your roll your gimble is going from one side to the other ,something lose?? look at 0.38 and son on in the movie
The gimbal is lose on the vertical shaft. I was trying to balance it by moving the camera forward and I forgot to tighten it. Now is good. Bill
Hey Bill, Whats the metal gear on top of the motor for the pan? Did you get something made?? Or can you buy it?? Thanks again.
Matt, The gear is a servo metal pulley. I had it in my junk pile I also have plastic ones but are no good. I think that pulley came of the Tarot servo. http://www.foxtechfpv.com/tarot-metal-32t-gimbal-server-synchronization-round-p-973.html I drilled the spline to 1/4", fitted it over the alu shaft that I made, drilled a 2.5mm hole then tapped it to 3mm and installed a grub screw or set screw to secure it to the shaft.
Thank you Howard. A bit more tuning and she is done. What I am trying to do is have the "follow" parameters on a switch so I can switch between Free follow and fixed follow. Bill
Well is like POI On free follow the camera will point in one direction no matter which way the copter is facing. On fixed follow the camera point wherever the copter points. Bill
Bill, did you get to fly? I got a quick test in, and, well, humble beginnings... The pitch control was way too fast for the camera operator (he's never done this before so there's some learning that needs to happen on his part too), and I'm getting a high frequency oscillation on the roll axis that I did with the older firmware; I have some tweaking to do! Endless tweaking.
Thanks Josh. The camera is a 5DmkIII. I just chopped the clip before it panned down to me Here's a continuation, you can get a better sense for the vibration issues left to tackle. I'm not sure whether the firmware and new settings are to blame, or whether the vibration damping on the new mount is dodgier than what I built for the two axis version of the mount. I can't wait to shoot and process some raw video with the new magic lantern raw recording...
