Mini lathe to make Painted Yahtzee
There one use I use smalls a lot for painting.? Need to cover badway and part lathe you do want dots on.? Here simple project that makes a lot women happy back in 1995 the had Painted Yahtzee for the computer. They never made dice for this game.? So can make your wife very with your lathe and nes 4 jaw chuck.? On the mini lathe you can paint the dice the different colors. Wash off dice using rubbing alcohol.? Use your 4 jaw self centering chuck and chuck up the dice for painting.? It takes 5 colors using Testors 9146XT Promotional Enamel Paint. Note you buy purple or mix that color.? ?Now just just use tool post to steady your and paint each color let dry between colors.? Some dates you need to use white in dots to stand out.? You only one on the block with Painted Yahtzee.? I have included the paint chat , score pads and rules in PDF in the down load section. /g/7x12MiniLathe/files/99%29%20painted%20Yahtzee%20on%20mini%20lathe%20fileI have used the lathe for a lot for painting?

Re: 7x12 Motor Won't Turn On
I have use them one time and they are great. They lot of little things that are hard to find.?
Ebay is like old west and try to avoid Ebay but have will throw dice ?.?
Remember they not like Amazon and Walmart on shipping.
? So I have few things plan to buy after I have larger order?
For resources I also use Amazon , Walmart and Home Depot too watch there pricing they very alot. You even find things at Hobby Loby

All,?
Thanks for all the suggestions.
The flywheel has 4 big holes so I will drill the holes out and mount it on my 4 jaw scroll chuck as suggested by davesmith1800.
Hopefully I can get it turned on my 7x12, if not then I will have to find a bigger lathe.
I think I bit off more than I can chew with this project, my X2 mill is also too small for some of the parts and they have to be done half way then removed and turned.
Anyway it's all in a days fun.
Thanks again.

I have made wooden fixtures using "T" nuts and a center spud to mount stuff to a face plate. John Mattis
Often, there are ways to get around some limitations.? A possibly easier setup than the faceplate is to bolt the flywheel to something smaller and then chuck that something into the 4-jaw.? Centering a part on the faceplate can be aggravating.

Re: 7x12 Motor Won't Turn On
ya could pull the motor & hook a volt meter to the leads
& spin it with a drill & see if ya get any voltage out .
I'd try to see if it spins with a tool battery first .

Replaced fuse.? Motor still won't turn on - new fuse didn't blow.

If anything is “blown” it is most likely one of the MOSFETs on
the motor controller PCB and not the motor. ? It costs about a
buck to replace if you can DIY, or more like $100 to have
someone do it for you. ? So it might be work reading up and
learning to diagnose this.
The first test I would do is to disconnect the motor and see
if there is power coming out of the driver board. ?For that, you
should replace the motor with some kind of dummy load and
measure the voltage. ?If the power seems good, the motor is bad,
but if the power is not good, it is one of the output
transistors. ? They are cheap but you have to know what you are
doing
There are a few other parts that can blow as a result of the
fuse or mosfet blowing. ??
Or if you are EXCEPTIONALLY lucky, a loose connection.
