For mini lathe

 

Here is a easy way to mill the flat for exstension on mini lathe .
Note the two drill bits in the vise.?

Dave,

Are you milling that in a drill press? (from the pic it looks like a similar model to what I have)

If so, how you keep the vibrations from loosening the taper and dropping the chuck?

I tried to do some basic milling of aluminum with my drill press with a pretty small end mill and I could't keep the taper from letting go and dropping the whole chuck onto the workpiece (and then onto the floor).? I finally gave up.

Dave,

It is a real mill?
It nice size larger mini but small than a bench mill.
You see more at?
/g/Drillmill/messages

To get you have order from China?

Dave?
 

The real answer is to use a machine that has a draw bar to keep the taper seated. Lacking that, there are some work arounds. The simplest (sleaziest) is helping the taper to stick with some cyanoacrylate glue - acetone, heat & mild profanity will help release it when you're done. The other approach is to cross drill the (usually soft) tang to fit a split or taper pin? that keeps things pulled up tight. If you also want a lathe project, you can make a screw with the head the size of the taper slot that threads into a tapped hole in the tang.

It;s a lot different that it was even 5 years ago . panels that were over 4 bucks a watt are under a buck a watt these days . I didn't think the Big Red group was still around . I have one buried on a bench at my old shop . It's next to one of the larger Mill Drills on the same bench . The guy before me tipped teh mill drill over when moving it &? destroyed the middle/idler pulley & its mount . It's totally different one then the one on Big Red , or I would have been using it for the last several years .

You can still buy parts too from China.?
It like any other China made equipment you finish it.??

I use tang and the draw bar together?
Add fine feed to quill
Torque arm?
Took out center pulley?

Now great mill

Yes loosing the center pulley is very simple on big red . On the larger round column mill drills the 3 pulleys are not all three in a line with the column sticking up so the idler pulley is offset from the front & back pulleys .? I'll see if I can find some pics .

Here where you can find parts is AliExpress.

They also have big red in green and blue.

Here a drawing on fine feed works on drill press too.
