    Fastenal around here doesn't sell individual screws they make you buy the bag... I don't even know how they stay in business no private citizens have any use for the place.... I might try that 1" screw that u suggested earlier they were like 85 cents I think
    and just get some thin lock nuts should work pretty good size wise.. now for those half nuts!!!

    This is a little OT, but... I can't comment on stockage or availability, but the other statement about finer threads being stronger than the same outside diameter coarser ones is obviously false. Look at any thread dimension table from Whitworth through ISO Metric and you will see that as the pitch decreases for a constant thread size (nominal outside diameter), the minor diameter of the thread increases. So in shear, the cross sectional area of metal in contact for one thread decreases as the thread gets finer. If the major and minor diameters of the male and female threads were all the same (no clearance and no allowance), it would be an exact wash. But since you have to have clearances in order not to be solid metal to metal (you couldn't turn it by hand) and allowances or you couldn't make it for less than megabucks, as the pitch goes down, the strength also goes down. It isn't much, and is generally ignored in thread strength tables (except for make-up torque). But it very obviously can't go up as claimed in that manual.

    Thanks scruffy ron

    Thanks scruffy I appreciate the offer but I've already sent my half nuts off to a guy that that rebuilds them. I found his posts on practical machinist when I did a Google search....he's quite a bit cheaper then the new ones from logan

    time for a little update I guess... well I popped out the spindle so I could put on a new belt when it arrives and cleaned up the bull gear and a few other parts... the spindle bearing seems to be pressed to the spindle, I don't have a press so I was wondering if I should throw the whole deal in the solvent then regrease the bearing or just leave it as is with some new grease squeezed into it? the outside bearing is still in the bore it looks to be a sealed unit so I figure theres no point removing it? didn't take any pics

    Some folks have had success washing the old grease out of the bearing and re-greasing. You have nothing to lose by trying, and it might save you buying a bearing. My experience with removing
    the bearing was that it wasn't too difficult. The "nut" that held mine on was made with a hook spanner in mind. Logan suggested I get if off with a hammer and a punch. I held it in a vice with
    a chuck of thick leather wrapped around the spindle, heated it up, and tapped it off. The bearing came off the spindle fairly easily. I pressed the new one on with a home made press of pipe and
    all thread.

    My old bearing was an original New Departure bearing with a seal on one side and open on the other. If yours is like that, you can hose it out with solvent.

    the bearing has no issues at the moment seems to be in good shape that's why I was wondering if I should just leave it...or clean it and repack....any issue with cleaning and repacking while its still on the shaft?

    Doing things correctly is never a speedy process (at least for me). You'll be glad you did it right.
