So, we have all the work done on the BT-30 ATC that also accepts a drawbar. If anybody wants one, they'll be ready in about 70ish days. Doing pre-orders now. Check out the webpage and let me know if...

So, we've decided to make a BT-30 headstock that can use drawbar or ATC petal clamp system. I like the TTS, but runout adds up when you stack a collet and tool holder together. Plus, .0001" to .0002"...

Ok, so we've decided to go with BT30 and we're now doing the pre-sale offer with free bonus upgrades. You can check it all out here: https://glockcnc.com/bt30-taig-sherline-headstock/

The ISO20 taper might be able to use the same headstock casing. The 30 taper will require a larger headstock casing to accomodate larger bearings. We want the taper further up in the bearing to...

The headstock style for the 20 or 30 taper will be the same as the R8 https://glockcnc.com/store/#!/Sherline-Taig-R8-Spindle-Upgrade-Headstocks-For-Mills/p/50894202/category=8597973

I'm in the middle of designing a new headstock that will fit both the Sherline & Taig mill. I already make the R8 version and use it with the Tormach Tooling System...but, i would like to now make...

Did you get your IH mill? If so, have you checked it's accuracy for both short and long distances? I went through two IH mills and neither was accurate. Let me know if you would.

Actually, the first motor for the 4th axis worked well...but, it quit working and I'm not sure why. It may have been because coolant came in contact with the terminals, but I don't know. After...

I too run a small business and would not personally buy any IH products again. In fact, I have requested a refund for the 5th axis setup that never was made or even wired in my mill like it was...

As an update, IH did replace the mill after many many delays and constant calls. The new mill works better, but the new ball screws have .002 in backlash in X and Y with .005 in Z...when I was...

Thanks for all the info and I will try all of your suggestions. The CNC mill came as a turnkey servo setup from International Hobbies and is brand new. It's done it from the get to. The ball nuts...

Thanks for your reply. I have inspected the encoders for debris and found none, however I have not tried replacing them. The other strange thing is that the Y axis will start to gain .001" per...

I have an IH CNC mill and Mach3 controller. For some reason, I can tune the motors to say, .200" and make a few test moves using my dial indicator check it. When I do the test moves, it always...
