I wouldn't put my fingers inside that while the bowl is spinning.
what happens if that bearing locks up (sawdust jam?)
or you get off center and the sandpaper "catches" and pushes your hand around.
too risky for the "reward"
That might make me more comfortable.I think I would incorporate a safety arm resting on the lathe bed to prevent it from rotating in the unlikely event the Morse taper ever came loose.
My thought exactlyThe "Lazy Susan" bearing was my first concern on this tool, all it would take would be
a small solid piece of debris to enter the raceway and potentially lock up the bearing.
I guess I was a beta tester, I have one that I rarely use, but I do use it from time to time. The leather interface that was glued on fell off while the unit was not even in use. I'm assuming that that issue was resolved after my beta testing report.
Did you all notice that the vase he was trying to mount using the tennis ball (1:55-2:20) just disappears with no video showing it rotating with this tail center doohickey? Either that clip wasn’t something they really wanted to show or the entire top broke off when if flew off the lathe and they just remounted the bottom of it for the rest of the demo.
There’s a little too much work shake in the demo for me to consider it an effective solution.
Cool!
Sort of an on the fly donought chuck.
I would certainly like to see one up close.
The video reverse of the HF with a ball is generally a poor practice.
The rims of typical HFs won’t take that stress.
Much better to have a support against the inside bottom of the form.
Or a bowl shape against the shoulder.
I must need one.
As someone who has spent 44 years as a safety professional in the insurance industry, that device is a Product Liability nightmare. The quality of the welds is suspect for a number of reasons, the "lazy susan" portion of his device appears to be very light duty and totally unshielded from particles or dust accumulation, there is a total lack of some type of appropriate safety device to stop the entire device from spinning if it were to come loose in the morse taper for any reason and breaking or severing fingers or catching a turning tool and flinging it at high velocity across the room. His video gives the impression that you can use his device in conjunction with a tennis ball to hold a hollow form. The video is very poorly done and without thought as to what he presents as the capability of his product.
I wouldn't touch this product with the proverbial 10' pole never mind providing liability insurance for it.
