very nice work - they look awesome

Did you notice the wholes for safety wire in the socket head cap screws? Very professional.

Were there holes in the whole thing?)

OOPS! Holes. LOL

Did some more work on the QCTP holder I am making for the lathe. Decided to make one that will "bolt on" the existing tool post holder to make it easier. I drilled out a 1/2" hole (finished with a 1/2" end mill) for a plunger, to force the toolholder out against the dovetail joints. I then drilled a vertical hole to the plunger hole and tapped it for a 1/2"-13 bolt for good torque.



I used some 1/2" rod to make a "plunger" and a "press rod" (for lack of a better description) to move the plunger out. Plunger has a 60 deg angle on it and the press rod has a 30 deg cone end. The rod will be forced against the plunger by a 1/2"-13 bolt, which worked rather well when i tested it out.



Here is the bits so far, but unable to cut the dovetail yet as I cant afford the R8 ER-40 collet set yet, and the R8 endmill holder I have is 1/2". Going to pick up a 3/8" R8 end mill holder probably tomorrow so I can continue. Here is how it will eventually go together, with the 1/2" plate bit welded to the post so I can clamp it in my existing holder.

Two days really.
I put the finishing touches on my cedar handled diamond point grinding wheel dresser;

I also started on a bowl turning tool rest for my wood lathe;
I converted an old tire iron into the top of the rest with some heat and brute force;
This is about 14 inches long OA
Then machined a post for the rest and milled a recess into it approximating the diameter of the tire iron for welding the two together, 3 passes with a ball end mill on the trusty South Bend Lathe of course. Tomorrow they get welded polished and painted

Well, after a week of waiting for a piece of plate to mount my little lathe on the bench I got bored.
While looking for tools and parts from various sites I got the itch to make something and here it is.
All made out of a piece of 1/2" x 2" aluminum bar a 1/4-20 bolt and a couple of cut offs from the parts bin.
All hand cut with a hack saw then to the belt sander for final sizing and fit then to the polisher for a clean up.
Not bad I think. happy I got to get some me time.

I might lower the locking arm a 1/2" to clear the compound later

I made my first gear today. It is one of a set of eight change gears for the milling table feed.

Nice work. What brand is your mill?

Nice job!
Machining at the basic level does not require expensive equipment. After all how were the first machine tools made? By hand of course

It's an Elliott Victoria Junior Omnimil, now thats a mouth full. Awsome small machine.
