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.
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.
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.
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
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.
