LOCKABLE SCREW-ON CHUCK BACKPLATE

Great video!!

Excellent job!

Great build! I really like that chuck retention setup. A side suggestion to help see better- I recently saw a video about using dentist glasses so you don’t have to get so close to whatever you’re working on. I believe they’d be super helpful when looking in a bore with a thread gauge for sure. The glasses are: Dental Surgical Loupe 3.5X Working Distance 360-460mm Burgundy Sport Frame Keep up the neat stuff sir.

@@orangetruckman G’day mate… cheers! That’s not a bad idea. I’ll have to look into that for sure 👍👍

Gday mate good to see you back again, nice job everything fit together perfect, shit of an idea with the damn hole pattern on the chuck being like that but never mind you got round it. Anyway good stuff and I'll catch ya on the next one.

[@NOideaMachining]

Cheers mate. Yeh, I think they just though she’ll be right mate, that’ll do 😆 Or someone was on the piss 😬 Nah they’re a great chuck. Pretty sure they were just avoiding other stuf.

That turned out great! May I suggest centering the rotary table by lowering the chuck pin thing into the center taper while the clamps are loose, and then tightening them once it's seated? Basically the way you centered the chuck. It should get you within a few thou, and might be quicker. I will definitely try your way though. Might be time to change your channel name to SOMEidea Machining, given how well your projects have been turning out.

@@sean.chiarot hey mate, cheers 👍 Yeh, I’d normally do that when I first put the dividing head on the table for initial setup. I did it the way I did this time because I had to raise the head which is crap on a round column mill. Rather than undo all the bolts and stuff about, this is much easier for me. Took longer than what it normally would take because I’m talking to a camera and not thinking about what I’m doing… and moving the table the wrong way 😆 It’s normally a 5 second job. It’s very accurate too. If you do it right it’s generally 0.01ish out of whack, if not spot on. Plenty close enough for a hack 😆

I have a similar hack for centering the Rotary Table, but rather than move the mill table around I loosen the RT clamp blots and allow it to find it's happy place, then lock it down, rotating the RT around whatever you are using to centre it with helps as well. Nice job on that backing plate and I'm glad to see you seem to be on top of your parting problems. 👍

@@MyMiniHomeWorkshop cheers mate 👍

[@RustyInventions-wz6ir]

Very nice work sir. It looks great.

[@NOideaMachining]

Thank you mate 👍

To take the back plate off the spindle, put the three jaw chuck back on the plate with some copper pads on the jaws so you don't fudge the finished surfaces and then use a pry bar through the jaws, or the chuck key with a soft blow hammer and break it free. Before you put it back drill a hole(s) in the edge, the size of the cross bar of your chuck key and then you can use that to remove the chuck in future instead of a socket in the jaws as you did earlier. Works much easier. I have a Myford ML 7and have done this on numerous backplates I've made. First one caught me out. Fortunately, I still had the 4 jaw attached, so removal was made easier, but the tommy bar hole followed soon after. Good luck.

[@NOideaMachining]

@@ronwilken5219 what’s wrong with the hex in the jaw though ? That works fine 🤷‍♂️

[@HP_rep_mek]

Great idea👍

[@NOideaMachining]

Cheers mate… dunno if it’s my idea, but I haven’t been able to find one like it so far. I’ve searched though… 👍

[@gangleweed]

Hmmmmm......I see the problem, same as the one I found a year or so back on my dividing head when I realized the chuck would screw off if the cut was against the screw on direction........I decided to Loctite the back plate onto the dividing head spindle permanently and just remove the chuck by unscrewing the mounting bolts.......a lot quicker and it works ......I have a 4 jaw chuck that fits on the same back plate mounting spigot as the 3 jaw chuck........now for my lathe,

[@NOideaMachining]

@@gangleweed g’day mate. Yeah I did the same thing for my old vevor dividing head (complete rubbish). I couldn’t go down that path with the dividing head I just built though. The whole point to that build was to make the dividing head with the exact spindle that is on my lathe. And then to take it the one step further and added the 5c collets to that spindle as well (which I’m proud of.. haha). So now it’s all interchangeable. I can unscrew the lathe chuck and screw it straight onto the div head without breaking down the setup, so I keep a perfect centre etc. That was the reason I had to come up with something different. It’s worked out well so far. Now just have to make one for the rest of the chucks 👍
