Pilot Joints

[Graywolf]

With some of the OB-1, Pred. 1 & 2, TigerX, the pilot only extends .125 to .150 past the end of the shaft. The pilot hole in the butt is .75 to 1.25deep, then the only surface area that rest is on the thk of the ss joint ring, maybe .125 width. My Question is, is that all that is required for a solid seat.


Thanks

I've never seen a joint .75 deep let alone 1.25 but never the less, the top of the joint is all that is needed for the shaft/joint surface contact area. In fact, a pilot should never contact the bottom of the joint area.

thanks, the 1.25 should hve been .25. I did not know if the side cleance
-.005dia. had any effect on how the clue flexed or feel of hit. Is that the differnce in a flat face joint hit, wood to phonlic?
thanks

Threaded bolts or studs are made to hold two items together, never to align two objects. Originally, piloted shaft/joints were made so as to align one to the other. There was a slight friction fit between the nub on the shaft and the inside of the joint and this would insure that the two would meet with the same tolerance each time. I believe now a days the pilot is mostly just traditional as there seldom is a good friction fit.
