Just got a 6JT Pro Series keyless chuck with a MT2 arbor. Chuck and arbor looked good and will work well in my lathe. BUT when I tried to put the chuck on my MT3-JT6 arbor for the milling machine it didn't fit at all. JT6 is supposed to be Big End 17.2 mm Small end 15.9 mm The chuck...

This little puzzle has been has been bugging me all day long. Finally I solved the puzzle and feel better now. If you are interested read on. Firstly I drew all three threads to scale M12, 1/2UNC-13 and 1/2BSW-12 they look like the first picture. Not until you lay them over each other do you...

Just before launching into a third draw bar I thought i'd just try it out on the two that I already have. Popped it onto the 1/2" WW and as suspected half way down the threads started to tighten and jam. Popped it onto the M12 bar and low and behold it went all the way in, no jamming and held...

That was fun, Got the mill in place, bought some M12 all thread and made an M12 drawbar. Took two attempts the first was over engineered the second was a little more rugged but looks like it will do the job. Today my first collet chuck turns up. MK3 pheww lucky that's the same as MT3 with a 1/2...

We wound up using a motorcycle hydraulic lifter. The sort of thing you service motorcycles on. We were able to walk the units across to the lifter, Pump it up to almost bench height and then slide it over to the bench space. That way no one needed to lift the units and there was no danger of...

sure, it'll be a bit squeezy but i think it should work well

New toys in the garage, All I need is some younger creatures with bigger muscles to help with getting them on the bench. I settled for the BF20LV mill and and L160 lathe. Should have everything I need to nail this draw bad thing once I clean the gunk off them. Wish me luck.

Thanks Peter, I agree, it's likely to work, but not likely to ever hold a 1/2 tool again. From what I see it's an easy job to make a new bar, so that'll keep me busy for a bit. Thanks for your offer to PM, I'll take you up on that some day I'm sure.

wow that is a bit different PS I had a look at what running a M12 die over the 1/2 WW thread, as some people have done. Looks like it might work but only 2 to 3 threads of the old WW pitch are meaty enough to hold a decent M12. in every 7 or so threads. Which means less that 1/3 if...

Spoke to H^F they import the unit with a 1/2" draw bar but the guy mentioned there was another importer that brings them in with an M12 draw bar. Does anyone know who this other importer might be? If they have a replacement M12 draw bar it would save making one up. BTW just placed the order...

Sounds like the best option is to have 2 draw bars. The 1/2" WW and the M12 this way I have the best of both worlds. Easy

Have to stop thinking about this mill. every time I do I come up with another question. The latest is. Does the supplied drill chuck and shank come with a threaded taper? If so is it a 1/2" WW that would match the draw bar? Which means if I make an M12 draw bar the drill shank is on no use...

Thanks that post was exactly what I need to do. The cad diagram was great, that will save a bunch of measuring. I have some nice stainless which should suit this job well. So all I need is get the gear and make the bar. After I practice a bit. Still don't understand how anyone can put...

Thank Peter, You have confirmed what I thought. If you look at the manual for the BF20 on the H&F site, they call out MT2 for all the collet accessories for that machine, which you have now confirmed is rubbish. I'll go with MT3 tooling. I'll definitely get the ER32 as I already have a...

Hey Peter, I assume you are running collets. Are you using a a collet holder with an MT3 or MT2? The user manual on the H&F site shows the collet accessories as MT2 which sound wrong to me. Any recommendation on collet size I hear ER32 are problematic in clearing chips when you right...

awesome. thanks

I don;t think this model can do that

I'm just about to buy my first mill and just before I placed the order I got totally confused. The mill in question is the BF20LV. The Hare and Forbes web site shows the spindle as MT3 M10. But I can not find any MT3's with a M10 thread. They all seem to be M12. Given this is a 9x20 very...
