I have a somewhat unique situation, in that I am spinning an object on a 1" ETD150 dead shaft. The object that is spinning on the shaft is two pieces, the main bar and a pulley which are bolted together. Both the bar and pulley have an oilite bushing pressed into them. The problem is they both seemed to have closed in different amounts. I can get a .996 gauge pin in one bushing and a .999 in another.
My shaft is measuring .9978", so it won't even go into one of the bushings. Given these are oilites my initial thought is to grind the shaft down so I don't risk closing up the pores in the bushings. However the uneven bore sizes now has me a bit concerned, as the object spinning will be under extreme shock loads at times and won't evenly distribute the load to the shaft or bushings.
After checking the oilite data sheet apparently you can ream these with a very sharp tungsten carbide reamer without causing too much pore closure. The problem is I'm not a machinist and I don't have a new sharp reamer to do this.
Does anyone have any suggestions to fix this? My gut tells me to have someone ream them.
