Ok, Working on my Johnson Model R band saw rebuild. But one of the parts is not available. I do not have the equipment to build a new one so I need to see if someone would be willing to make a new one for me.
It is 0.500 in dia and 11.750 long, Has a hole approx. 0.2865 in dia hole all the way through it. and is threaded with 1/2 -20tpi 0.500 long on one end and 3 5/32 on the other end. The item is the shaft for the hydraulics and has a very long adjustment valve that runs through it into the head of the plunger. The original is bent, and looks like someone took a vice to it.

I am willing to send the old bent one to someone to go by, and pay for the stock needed and the new one. Just let me know if someone would be willing to do this and the price.

Oh, if this needs to be put somewhere else please move it and let me know
Thanks
 
Ken,

I can drill it from both ends with a 1/4" drill which I have. And then drill .286/.287 for an inch or so if it's needed. Oops! there is no drill for this size. Your choice is .2812 or .290". Is there something that requires the ID to be .2865? I have a piece of .500" turned ground drill rod on hand I can make it from.

The other Ken.
 
4gsr,
The only reason for that size is that is what the old one was, But that may be the .290 that has been messed up on the ends. The thing needs to have clearance for a .250 rod to go all the ay through the center of it. That is the adjustment valve that controls the close rate on the hydraulics. Have got most of the rest of the hydraulics cleaned up. but figured it would do me no good to redo the top for a bushing with a bent and damaged shaft. Oh, by the way the gears are in one is mounted on the shaft, and the other shaft is soaking. Then comes the bearings and a seal.
Most of the saw has had the heavy rust removed, and now it is just prep all the pieces for paint.

Ken,

I have a 9/32" (.281") drill bit that could drill it in one pass. I would rather drill from both ends and meet in the middle. If you like, I'm willing to give it a try. I have a .250" rod I can use as an gage to make sure the hole will drift properly.
 
I had thought of the drill from both ends but my little sherline is just a little short to even do that and I'm not that good yet and figured that would not get them lined up even if it did. If you think it will work I'm game.
 
I'll play with it this weekend and see what I come up with and let you know.
 
You might do a search for 1/2" canulated rod. You might find something close to the dimensions you seek.

Ken,

I just about have it done. At least getting the hole thru it. I'll get the threading done in the next day or so and get it mailed to you.

BTW- The mis-match in the middle is about .020". I over reamed it with the long drill bit and the 1/4" rod falls thru it without hanging up. Took about 30 minutes total to drill the hole.
