Jim --- while it would be interesting it won't happen. Rail Guns are only used at to distances, 100 or 200 yards.

Is that all? I figured with the fine adjustment you have there, that those were for long range shooting. At that range, with good ammo, you should be able to have pretty close to bullet size groups then.

Sophie and I have been married for 45 years now. April 4th will mark 46 years. We have traded on liners like that the whole time. I remember one when I had a few machinist friends over for coffee. The handle broke on one of her pans. She told me I was not mechanically inclined enough to fix it because it only lasted 9 years from the last time I fixed it. She then asked if someone else could fix it this time. I got razzed for a while about that one. Marriage is give and take. Sometimes you win, sometimes you get the short end. It's supposed to be that way.

Did I say Monday? The mail brought the new Bearings (Left) Much tighter class than the Flanged Bearings (Right). This meant new towers would be needed. Old towers in the center. Done all but the Bearing Pockets. Got new Dial Indicators yesterday also.

This is looking cool. The micrometer head is really sharp.

As soon as the Aluminum arrives Bill, the main base is next. This will tie together everything we have made so far.

Larger dia. and shorter these knobs are for the leveling feet. Aluminum for the base is 9 days overdue now. Just picking at things to keep busy. Without the base I am extremely close to a standstill.

After talking with shooters of these things it is a fact that the tighter you lock the elevation tower the tighter the groups will be. Soooo, we swapped out the front locking bolt and knob for a larger one to get more torque. We also added a lock nut to keep it from backing off.

Weight transmits rigidity and that translates to accuracy.

Hey Bill, I see that your locking bolt is brass. Is the surface it 'locks' steel or aluminum? Just wondering about surface damage when you crank that locking bolt down. :)

The locking bolt has a nylon button on the end. I copied it from others. They have no trouble with slippage or damage.

Now the Bad/Good news, my supplier decided he did not want to cut the 12 foot long piece of Aluminum. Translation -- He found a buyer for the whole 12 foot piece. This will prolong the agony for a week or so. I found another source , called and ordered a piece 1.5 X 10 X 36 for less than $175.00 S&H included.

Schools in boys and girls. This is for you new people that have never seen Adjustable Parallels used. The cross slide must be centered. The Mike Head is set at .500, this is going to act as "0" setting. It will give me plus or minus .500 movement of range for the Cross Slide. At .500 the distance (right side) is .617. To maintain the .500 movement this must remain. Now the other side needs to be moved to get to .617. The smaller distance at this point measured with the Parallel and Calipers is .401. Subtract the .401 from .617 and you get .216. That .216 is how much you need to move the left side out to get to .617. Once moved you will be perfectly centered. It will be moved by lengthening the two guide rods .216 inches. Now you need another tool huh.

The Mike side (fixed) is still .617. Fitting the new Ground SS rods brought the other side to .618 and that is where it will stay.

I was kinda wondering how you were going to do this on the 8520. Figured you'd come up with something to surprise me yet again. :)

You ain't ready for this Bill. Since the longest continuous cut on the Base is 16.000 inches I will be using my 8520 mill to make it. I will build a sub-table 12 X 24 inches 1.5 inches thick fron plywood and bolt it to the table. It should be rigid enough to do the job. Stand-by for updates on this.

16", that's it? Piece of cake. ;)

(I've done 24" easily enough, but wouldn't want to do much more)
