Wow, that ball is pure class! It doesn't even look like it was turned now! :bow:
SPiN Racing:
THANKS! Guys!
Sorry its taking so long. It seems I have a project for SWMBO tomorrow when I get up... so I may not be able to get into the garage till late, or even Friday :(
BUT.. Next step..
Drill the pivot, and slot the shaft, and umm cut down the end of the handle to fit inside the slot in the shaft.
And of course make some screws of some sort to keep things in place...
brass bushes for the nose and pivots.
If I could figure how to do it, I would put a bushing on both ends of the drill shaft. But I think I may just go with one longer bushing... Im thinking 1.5 inches or 2.
I think I wil lap the parts before doing the bushing so the shaft is "ground" to fit LOL.
<jots not to buy lapping compound next time past the automotive store>

WELL Sorry for the delay.. I went ahead, and got some shavings created tonight. :dremel:
FIRST..... THank you for the suggestions on getting the tool body mounted properly.
I used the Bogs method, and as suggested it was a snap. (Doddle? or Dottle?)
First mounting it was a little bit off.. so then I adjusted it sightly.. and VOila it was dead nuts on. 4 pics to show LOL.. :worthless:
Next step for me was to make sure I drill it in the proper spot. The slot is 2 inches wide. The end of the body portion was .8 inches. Sooo I needed the hole 1.8 inches inward to get to the right spot.
Wobbly Edge finder
Wobbly in use
Next up needed to move inward after finding the edge of the vice jaw .314 so that I was in the proper position for drilling the pivot. ANNNNND I measured it twice....... and went .414 :doh:
Here I am making a flat spot with a end mill before drilling it.
Drilling the pivot
Drilling the access hole so I can get into the center to put the bolt in.
Widening the non-tapped side to .25.
Tapping the hole for the pivot. 1/4-28.
Drilling AND Tapping the shaft the chuck will mount to. BEFORE I CUT A SLOT IN IT!!!!!! (I can be taught)
Here we go... stuck a very tight fitting Allen wrench into the hole (I check to make sure it wasnt bent first with a machinists ruler and light) and then used my dial indicator in the mill to make sure the hole was at a right angle to the incoming slot.
Then Used a .25 mill to mill the slot in the shaft. I plunged in about .1 or so.. while cutting sideways.. so it wasnt a complete plunge cut. I find it cuts a slot a lot easier if you are moving sideways while slowly deepening the cut. Then I make a pass back across the slot making sure its the right length. Then repeat getting deeper with each pass.
And here are both shafts... I need to now cut down the lever so it fits into the slot, and is ready to do its work.
Going to have to make myself some jaws I think, so I can hold the hex in the vice properly. That or I may just chuck it in the mill and take the points off the hex. and then lock it in like that. Need to ponder it first.
If you notice.. the shaft that is slotted.. is now all galled.. and has some scratches in it.
I decided to be slick and LAP the shaft with lapping compound.
It was a good idea......... BUT.. I was a tad.. DUMB. Turns out there was a tiny piece of swarf.. .and it fell onto the shaft as I was lapping it. Of course.. I was hand lapping for 5 or so minutes.. and things were getting good.
Then I decided to POWER lap it... by turning the lathe on.... worked good... nice... BIND. Uh Oh.
Soooo then I commenced the next 30 minutes carefully tapping the shaft out with a punch.
The shaft had a nice scratch down it as did the hole.
SO then I had to commence with about 45 minutes of careful filing to take off the scratch and some work getting the hole smooth in the spot it bound up.
Now things are back wehre they were.. but it was a bear.
Next......on my list...
finish the handle.
make the bolts to hold things together..
Bore things out to have brass bushings in the handle and shaft.
Cut a JT-33 end for the shaft
Make a MT-2 Arbor with a 5/8-16 thread... as the arbor I bought for 3 dollars is not true. :doh:
Darren:
That is looking like a really nicely executed project, nice clear pic's too :thumbup:
Bet it's gonna be a great tool to use when it's finished... :dremel:
