Some time ago I was foolish enough to buy a silly little Harbor Freight 3-in-1 machine from an eBay vendor that sells their returns. Anyhow, that was a fiasco. So I made the best of it by utilizing some of the not destroyed parts.
I decided to try and fit the stock 50MM (~2.5") 3 jaw chuck to an adapter so I can use it on my 109 (If I ever get it put together...) The 109 comes with a nasty little 4 jaw chuck that is usually worn out by the time somebody like me gets one of these lathes.
So here are the results of some tinker time in the shop.
Material is 1-1/2" T6061-T6 round bar. I cut off a 1/2" slug from the bar. Trued it up in the chuck. Center drilled, drilled out to 19/64 for tapping to 1/2"-20.
Tapped the part. Deburred. I then placed a mandrel in the chuck, made sure it was running true (less than .001" runout!!) then screwed the disk onto the mandrel and got busy making chips.
It took me two tries to get the fit right. My first attempt resulted in the register being ~.003" too small. (DOH!) I got it nailed the next time. It fits the adapter better than the spindle from the dead machine.
Match drilled and tapped for the stock 4MM screws. Now I need to get busy and fix my little 109....
I apologize for not taking more pics.
First pic is the slug I cut from the bar getting center drilled.
The last two shots are the part shown with the chuck and spindle from the dead machine. Last photo shows the part on the chuck.
Was a fun little project. Thanks for looking.
