Re: Mini lathe to make Painted Yahtzee

 

I should have named this thread?Thing you can make to make your Wife happy you own a mini lathe.?

It would a better title even if just minor thing on thd can make a big difference in your life and your lathe.?

Some wives have hobbies that make easy. This one more universal to most women.

Please post your wife's happy? turning?

Dave??
Re: how to.inspect.motor?

 

You spend a lot time looking and a little bug could have die.
Thd other is over look is a losses screw just enough to test good but when? power is apply nothing.? I do not think a it is a losses screw on your lathe

Bugs was use for thousands of years for making Shellac.?
He little clip from internet on using shellac fof electrical insulation.?

Shellac was used for fixing inductor, motor, generator and transformer windings. It was applied directly to single-layer windings in an alcohol solution

HEre’s an exploded diagram of a very similar one; this is pretty much how all the 7xNN lthes are built because they’re all the same design, with consmetic differences.


Also Ted Hansen’s book??has a section on removing and adjusting the motor

The Mini Lathe is probably very old, I have had it for 10 years, the previous owner probably 20 -30 years.


The motor is encased. How do I remove the cover?

The problem is more likely to be in the controller than the motor - motor problems usually keep the motor from running. (That's based on experience with brushed motors - I've got no experience with the newer brushless ones.)

It sounds like a cracked brush

Re: how to.inspect.motor?

 

I have seen problem with lock rotors too.
Does motor turn freely??

If brush problem like talked first part look for a dead bug.
The old term get bugs out or debugging start with real bugs under contact and brushes.
Now it is in electronic terms.

How to inspect the motor.

1st Step: Remove the rear shield!

2nd Step: Turn the lathe around 180°

3rd Step: Remove the two screws holding the motor cover in place.

At least this is my best guess looking at the great Fusion app, thanks Chris.

In theory you can check the brushes by removing them through the holes in the motor cover and the lathe bed. In practice they never seem to line up with the holes. To view the motor you just need to remove the 2 screws at the top of the cover the power cord goes into. To remove the motor you also need to remove the 4 screws that secure the control panel to the head which allows you to disconnect the wires to the motor and see the 2 nuts that hold the motor in place. You probably will need to remove other parts to remove the nuts.

Ralph,
.
I'm going to offer that you may have a broken plastic gear inside the lathe.?
The klunky sound, sounds like a missing tooth being engaged by the other gears' tooth, and finding nothing there until the next tooth comes around, and they then hit point to point.
.
To access the motor simply turn the lathe around to the back side, like a record player, and the cover, and then the motor are right there.
.
A possible 2nd option that happened to me once was the motor mounting bolts vibrated loose. They are behind/inside the electrical cover on the front side, bottom right.
The motor was banging around loose, and hanging at an angle, chewing on the belt a little bit.
.
Good Luck

Here is a 3D CAD file of your mini lathe. ? The link is for an online web-based viewer. ?If you have the full version of Fusion360, you’d have better tools to inspect the design (or even to build a minilathe from scratch.)

But even with the web view, you can rotate and zoom and EXPLODE the parts to see what is inside.

One good tool the the “model browser” (5th icon from the right. ? This puts up a list of parts and you can remove some of them. ? ?If you remove the case and covers you can see how the internal parts work. ? ? All the screws ?are in the model too so you can see how to remove the covers.

I did not create this file. ?I did clean it up a little. ? My use of it is to build a CNC conversion. ? The model is accurate enough to do virtual test fits of replacement parts.

Re: how to.inspect.motor?

 

There is list ov thing can.?
I would check burshes.??

The motor playing a tune does not sound like board.?

This type usd a DC type motor can be other problems too.?
But easiest to check is brush.?
Sometimes you need to clean the comutator too.

Does sound like a playing a tune brushless type motor.?

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.
