UPS just arrived with the 1018 CRS (1.5 X 3 X 12) for the "Pivot Block". The "Pivot Block" is the last major component of this project. We start sometime tomorrow.

Step drilled the elevator hole to 1 1/8 inches. Now we bore to 1 1/2 inches. The binder is locked in place during this operation to get the correct size and location. In the second picture you can see the binder.

After tweaking everything is parallel. Tomorrow is shop cleaning. It hasn't been done in a week or so.

Looking very good, Bill. I see you didn't use brass for the binder. Is that because the column is SST? Dissimilar metals and all?

I'm thinking I'll use CI for the pivot block, since I have some 1 1/2" thick.

The original was built with a drill rod column. It had a brass binder. The gent replaced it because of slippage. I have been having very good luck with 7075 for binders against hard metals. No slippage as yet. All of my binders to this point have been 2 piece. This one is 1 piece. I'm not sure how it will hold up. This is a first for me. The column on this one is 303 SS. Time will tell. CI is a good choice for the pivot block.

No clean today either. I want to get this last major part done today. The two steps for the swing adjustment are done here. Just the two pivot bolt holes to go. The print calls for two set screws with 60 degree points. I am going to use shoulder screws in their place.

Pivot holes in the frame are drilled and reamed to .375. Now to transfer them to the pivot block. Then drill and tap the block. This will complete the pivot assembly.

I sure am glad this assembly had no binding problems. Now all that is left is minor in comparison. The light at the end of the tunnel is much brighter now. :rofl::rofl:

Thanks again for sharing, :applause:

I was thinking of sending a shoe-box full of dulled end mills that I need sharpened. :))

You guys are something else. I just want to see it work. :rofl::rofl: 98 days so far, average 4.6 hours per day = 441 hours so far. Materials, don't go there. :lmao: It really is nice to know what you guys think. This was not the everyday, run of the mill project. The pressure is off and it should be smooth sailing to the end. As for the video, we will see.

At $50/hr that's $22,050.00. At $4.00/cutter (what some random Web site is advertising) you'll earn that back after only 5,513 cutters.

Been busy working on the bridgeport so I aint kept track last few days. Looks good. When you say one piece binder, do you mean it's cut to fit the radius of the shaft it's binding and works kinda like a set screw?

Looks great Bill

Chuck;

I will be working on that binder today. You will see how it works as opposed to the other binders. Stay tuned. Nice score on the Bridgeport.

Here it is, the binder, the cap, and the nut. With the binder in place the cap goes outside the frame. The nut pushes against the cap and in turn pulls the binder out to tighten against the shaft. The reason I am a little skeptical is that the binder is only holding from one side. On a split binder both halves hold. The jury is still out on this one.

The jury has reached a verdict. That bushing is held in place by a minimum of pressure on the binder. A hammer won't move it. Looks like it's a keeper.

Very nice and not at all what I had pictured. It kinda side loads it which is what I was thinking. But I was picturing a shaft with the radius cut in the end. That would more or less press into it as it was screwed in.

At any rate, nice man

The end is near. Odds and ends and then mounting. This is the first time all parts are seen together.
