Good job thank you for sharing i'm impatient to see it running with a real job 👃

Me too. Hopefully I'll get something up soon. I have a bunch of different things I'm testing right now, so I have to round robin between them 🙂

@@vonsyp ya, I'm curious about really long bits too, they tend to work loose when you push them hard.

i love these things.

Great video, as usual, Jim. I'm wondering. How is the correct torgue on the collet nut achieved? Is there some kind of clutch mechanism in the feature that holds the collet and nut in the tool holder?

@JNWoodworks

It isn't really a clutch, but just 3 steel balls mounted in the plastic housing. They grab the nut and stop the motor from rotating momentarily, so its just the inertia of the motor tightening the nut. It sounds like a harsh thing to do, but 1200rpm is actually very slow and it just makes a little clicking sound when the nut is jammed in there. I have to test the torque values to convince myself that its enough, but the company has done a lot of testing cutting metal to see if there is a problem with bits coming loose, and a quite a few others have used these already and I haven't heard of any issues yet. Time and testing will tell.

How is the connectivity achieved on the Z touch off between the brass plate and router bit? When done manually I usually have to attach the magnetic coupler to the router bit.

Someone else asked the same thing on the FB users group 🙂 This was my initial response: If you look close you can see my magnet is stuck on my rotary unit, so it connects through the chassis. The connection through the chassis and spindle has been reliable on my machine. I've been using it that way for over a year and the touch has not failed, which is more than I can say for me trying to remember to connect the magnet to the bit every time before that. Then there was a question about if ceramic bearings would conduct: They do, but usually only the bottom bearings are ceramic, and the top ones are steel. I was skeptical at first so I did a bunch of repeatability testing and my spindle has never failed to conduct. AVID measured several spindles there and had the same results, and quite a few people on the forums have been doing this too with the AVID spindles. I have heard some spindle models actually have a contact built into the motor to ensure the shaft is grounded as well.

hoping youll be posting a video on the auto tool changer...?

Yes. My next step is to do some reliability testing to make sure it is very repeatable, and then do a full automated run in Gcode to test the whole thing. I will do a video on all of that combined once I get through it and I am satified I know its worthiness.

Me being a previous mech eng. I would say this is a great idea, but you may want to look at your threads a little more in depth from a starting stage and then count off on how many changes you have to see if there is any deformation of the threads over time. awesome setup on the table!

Thanks. ya, I'm definitly going to keep an eys on the threads, the nut surface, and the wear on the steel balls in the cartridge.

I think "IF" this works out to be a issue a new thread lead to pick up "then" tighten could easily be implemented? thoughts?

Nice! Think it would work with dust shoe on?

Ya, the dust shoe is an issue I have to deal with yet. Its the same for the regular type of ATC too, most dust shoes get in the way. My particular dust shoe is pretty wide, and the sides of the magzine on mine are raised because this is the model with the motorized lid. They make a version with no lid, and that would probably be fine, but I want the lid so that the collets stay clean. I needed to make a new dust shoe anyway, so now I have a new design criteria to add to that :-)

So no air compressor needed? Looks good waiting for a good atc to come out with the avid.

Correct, no special spindle, no air or solenoids, etc. No big racks or tool holders. Really nice for smaller machines, hobbyists, or people who don't have the money for a full blown ATC, or can't get an ATC spindle on their machine. Honestly though, I think this would work fine for a production shop on a big machine too.

@@JNWoodworks Good to see more options coming to ATC

I dunno. it seems to me this is a good way to get a cross threaded collet and trash your spindle. I didnt even know anyone was working on an ATC using actual collets.

Everyone has that concern :-). The guy who designed it did to, but hes done a lot of testing and so have others. I plan to as well. However, its spinning very slowly (1200rpm) with very low torque so you're not likely to mess up the threads even if it crosses, but the chances of a cross thread should be low too. I plan to load up all 6 postions and run it through a couple hundred exchanges to see if it ever fails as part of my testing. I'll have a full review of all of that when I'm done.
