Group Project: Dividing Head - The Build

[ErichKeane]

Knocked out my last 3 acme threads this morning. 2nd of the day went poorly and got a nasty gouge out of one. Guess that one is mine
A little too hot to work more today, but the center sections were reasonably quick on the other two bars. Hopefully they will go quick enough that I can move onto the gears soon.

Thinking I might do the gears hobbing on the mill, it solves one concern I have plus means I don't have to make up any more jigs.

Those look great! Weather is getting cool enough to cast more gear blanks...

Well I have the first piece of the sectors almost done. I just have to bore the ID to size and cut the slope on the arm. Working on the setup for the sloped part and to hold it to bore the ID.
Then I get to start over on the other part and see if they fit together.

But at least it kind of looks like the drawing.

Then I get to shift gears and figure out how to make the sheet metal clamp piece.

I just bought the 1/8” end mill to mill the slot in the spindles.



I will upload a picture right now of the almost finished spindles.

I am going to finish these on Sun., 10/3.

The only problem with these is that *one* spindle has tight threads. I will keep that one for myself.

One more picture.

Along the way, I biffed 4 spindles, so a 67% success rate.

They look great. I should be getting back into doing some of my parts very soon. Life has gotten in the way so much that ive been doing more important things first to even get to doing more of our parts.

I am glad that I knocked those out before things took off at work. I guess I knew what was coming.

Nobody needs to feel stress to finish on my account. I am never in a hurry: not with those spindles, not at work, and not ever.

Those are really beautiful. That's some work to be proud of.

Those look beautiful. Puts my work to shame.

I'm putting the lasts feature on the spindle locks, the clamp screw hole. I think I'm going to have to redo a couple. Especially seeing what the competition looks like.

BTW, I deviated from the plans. They call for triangular cutoffs from above and below the screws. I made a turn table(?) from a crap chinesium vice (video to come), and milled an outside radius to that there is a constant thickness section about an inch long. This will spread the bending necessary for the clamp action to be spread out across a larger area. The triangular cutout would force the bending to all be in one spot.
