My apology to those that I said I would send the initial prints to. This has evolved so much that they are rendered useless. Again, I apologize for this.

Finally found a bearing supplier/manufacturer outside of China. I don't use their bearings unless absolutely necessary. "Omnitrack" from England has exactly what I need. I need a Transfer Bearing with a .500 Ball that has more than .125 of the ball visible. Their 9000 Series is the perfect one. It has a 100 lb. load capacity. All Stainless components. Pricey but worth it.

A little more time and elbow grease and it will look spiffy clean. If nothing else this railgun will be a showpiece. Might be a candidate for Cabin Fever 2017. LOL The Brass Round will become the 4 new handles.

Four knobs with their profile and threads finished. Now to the mill and eight flutes. 1/4 inch bullnose cutter .050 deep. Then all that's lest is to polish them.

Lots of goodies came today. Bearings, Brass All-Thread more Aluminum. This is going to be a showpiece for sure. I was going to anodize Green but this would look wicked in Black.

OK folks, had to back up a bit. I anticipated the bearing size from the print. UH-OH , should have known better, the print only showed one size, not mine. You can see from side by side pics the modification I had to make. I live for this stuff. "ROTFLMBO" The new bearing holder is the old one with the top removed ti the threads. Then it was faced flat and a .500 hole bored 1.5 deep. The new top is pressed into the .500 hole.

After a little more machining and modifying all three bearings are correctly mounted. Piece of cake. NOT!!!!

The original center carrier was made from materials I had here. It was three pieces of 1X1.5X4. They were pinned abd bolted together. I didn't like it from the beginning. I made a new one from a 1.5X3X4.5 piece of 7075. Much better and I feel better about it. To the right is the old 3 piece unit.

After more thought it was decided to convert to a single lock on the carrier. It will save a few precious seconds in competition.

Still more modifications. The old side plates (Right) are .250" to short in height. This was not seen till the windage assembly was checked against the Elevation Adjustment. Not a problem as you can see. LOL

Now we go crazy. I found a Moore&Wright 0-1 inch micrometer head that is 2 inches in diameter with a .001 resolution.. It will replace the right hand adjustment screw. Also a dial indicator will be added to the right side. Why, because I can. LOL

Bill- There are times when it gets tough to finish a part up. My mind is always at least one step ahead. Then, like in this case, the question of "What If" dominates the process. It's tough bein me, but somebody has to do it. LOL

NOTE TO SELF:

Sister in law is ready to go home. I said I would be right there. She said NOW, I said feel free to use the phone to call a taxi. Wife gave me a real snooty look and said what if she goes with her. You ready --- I said I'd pay for the taxi and a healthy tip to the driver. Then the fight began. ROTFLMAO.

Micrometer Head came today. I bored the right side to .500 and now just a .750 counter bore and set screw are needed. I can do no more to this assembly to get it any more accurate in settings

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