Never even heard of that, but that also looks great!

Any thoughts on the new Langmuir offering for a personal CNC? I thought the specs are pretty impressive for a CNC mill compared to something like Tormach's similar sized offering. https://www.langmuirsystems.com/mr1 It'd be nice if it were setup for ER32 collets, though... only ER20.

I bought a tang screw for the MT2 taper shank integrated into the collet chuck, but it seems to require some machining in order to fit properly. Last night we turned the outside diameter of the tang screw down to slightly less than the Morse taper at the top. That worked out well, but now the...

Yeah, I ordered a tang last night. I did try to fit a 3/8-16 cap screw, but the protrusion of the bolt head was excessive and wouldn't allow the Morse taper to seat properly. I realized that it would be a major PITA to remove the shank once installed without one. I also picked up a Morse...

So should I invest in a screw-in tang or leave it out? The downside is if I decide to reinstall a 3-jaw chuck in place of the collet chuck down the road. Not sure how I'd get the non-tanged arbor out.

Quill does indeed have a tang slot.

The new MT2-ER32 collet chuck does not have a tang installed on its end, but has a 3/8-16 threaded hole for one. Is it necessary to install a tang? I suppose it would make it challenging to remove the chuck once installed without one. Otherwise, it's just more mass and a potential misaligned...

I bought an MT2-ER32 collet chuck and a couple sets of collets from Haas as they're currently on sale.

The chuck you posted earlier appears to be one of the only options for a 2MT-ER32 chuck. I believe Accusize packages this collet with a set of 11 collets as well, so that might be a good option. I also found that Haas has a set of ER32 tap collets on sale currently...

I was getting slippage with my stock JT33 3-jaw chuck on the tap shank, for sure. I was only able to power tap to 5mm before slippage occurred, but it certainly made enough progress to allow me to hand tap the remainder. I think I have ruined my JT33 3-jaw chuck at this point, so am looking...

Haha I was researching and came to the same conclusion myself! Thanks for confirming that one!

My application is basically tapping NPT threads into aluminum. One of the taps is for 1/4" NPT threading and the square shank is 10.7mm (0.42"), which puts it into the M18 category tap size. The other tap is a 3/8" NPT thread where the square is 14.5mm (0.57") and puts it into the M20 category...

This machine was definitely designed for something like tapping. You can set the depth at which the machine will reverse the drill rotation precisely. It will even auto start the process if you want. It runs down to 100 RPM simply by turning the dial, being controlled by a VFD. I'm pretty...

I've got a Nova Viking DVR drill press, which is a really nice machine for my purposes. However, the chuck it comes with is a JT33 unit (3-jaw chuck) that doesn't work with square drive taps. The arbor tongue is a 2MT. Is there a practical upgrade I can perform to accurately drive square...

Solid! Wiring easily replaced and repaired.
