Very intetesting video. The R8 collet system is great. So many choices and a lot beefier than ER16. I hope you have a wrapup / review video when you complete this project. Imagin, your very own Transformer.
I'll absolutely do another video using some tools set up in TTS holders along with a Haimer for edge finding and height setting. I'm looking forward to it, but need to move the Y and make a few other small changes first.
Great demo of it working, well focussed and explained. Now I understand exactly how it works and can start my own. Where did you get the air cylinder? I only have 100 psi in my shop. Is that enough?
I don't know yet, as I need to make a few changes before I can make some parts. With the motor and pulleys I have, it can go up to 14,000 RPM. I believe it might be able to handle that, but I'm going to start with 10,000 RPM for some jobs and see how it does before pushing it higher.
I'm using a Dewalt 4.5 gallon compressor rated at 200 psi, which I needed for my injection molding machine. The power drawbar only needs about 115 to 120 psi, and it doesn't use much air at all. So pretty much any compressor will handle it.
That answered a million questions I had about these types of power drawbars, thank you.
Glad it helped.

I purchased the R8 spindle and power drawbar as a kit. There is a link in the description where you can find more information.
Great setup John.. mine is still ER16, want some detailed info how to upgrade, is your Taig lead screw or ball screw ?
Please see the links in the description for this video for details.
Good looking setup, John, how many RPM's can you top out at with that motor and spindle (reliably)?

@@JohnSL Interesting, John, thanks for that-
That drawbar is dope, the whole spindle assembly sounds awesome at 1600 rpm - What kind of compressor/air system do you use in your shop?

I love your upgrades. If you ever consider selling, I'd buy.!! Great job.👍
