Hi all,
I've read tons of wisdom in all the old posts from RCM folk on how to use bowl and tub vibratory tumblersand media and have been looking on ebay to see if the "buy used" option presents a better deal that building. But not as much fun, of course.
Could those who have built their own provide an update on their experiences and satisfaction with their own designs?
For those who use either commercial units or home made tub types - how do they couple the motor to the shaft with eccentric weights? I saw one reference to a sloppy belt setup. If not a belt, there is a huge (intentional) vibration in the tub, how is this isolated from the motor? I've looked in the McMaster catalog and the Tire couplings (e.g.
6241K22 on page 1006) might be suitable but overkill? What about a big spring between the motor and the vibrating shaft?I've watched the video on the Kramer website:
I have seen many references to the benefits of trickling or spraying a suitable detergent/water mix into the bowl/tub - but am not sure how it is gradually removed. Does it just trickle out through the door of the tub style units into a catch tub where it gets filtered and recycled? Or is it lost due to spray mist or splashing? I understand too much liquid reduces the efficiency of the derburring process so the liquid level needs to be maintained.
I'm looking to build (or maybe buy) a unit in the .75 cubic foot - 1.5 cu ft range to debur machined aluminum parts up to a couple of lbs in weight and in some cases - prior to anodizing.
Thanks for any suggestions.
Cheers, Peter
