A Lottery Drum For Spot Prizes at Church
A Lottery Drum For Spot Prizes at Church
Description: My daughter and her boss has asked me to make a rotary drum up for lotto type draws of numbered ping-pong balls.  So after various requests to plastic outlets, and their quotes, I decided to make on up myself after they had cut the pieces to mydesign accurately.  They also supplied two tubes of solvent glue.

The image shows the drum finally assembled but not complete.  There is no "hole" to reach in and draw out.  That will be a slot with a sliding cover yet to be made :)  Some shaft bushes are not stainless steel and will get painted.  So far there is about $500 of materials and 40 hours of work.

I must confess that I had some welders make the A-Frame to my design and they helped supply some of the bits and pieces from left overs but I bought the nuts and bolts and shaft collars.  It was all done in CAD on the computer first... - a secret draw hmmm, its for spot prizes for the Junior Church 5-12yr olds :)  A bit spoilt for such an expensive aid...  a one of a kind though.  It would cost $2000 commercially!
