UHG please tell me you didn't realy bend the ways!!!!! Glen those are a relatively precision made parts the only reason there should be any slop or play would be due to adjustment or wear bending is not an option even if they were bent for some reason or another. You may have compounded your problems. They were heavily sloped due to wear bending. I made them to how they should be.. It had 4 adjustments for the pieces that when fully tightened did not make the vice stable (I had no choice if I wanted a stable vice) I only had to bent the metal by a few degreese, it is the 2 plates on the bottom of the carrage, they looked like they might not even be originals. Rockoonz My nelson is totally different from the highland parks saw... I looked at a video of how they adjusted it and I can't really compare my saw to that one

Glenn I'll explain a little more then drop it. The ways or rails that the vise rides on are a fairly precision part not to NASA specifications but probably to a few thousands of an inch, and are aligned to be parallel to the blade I don't care who you are one can't take a worn part and repair it by bending it. That saw is 80+ years old no doubt it has worn parts and now it has worn and bent parts. Finding new parts is probably not doable but there is an an alternative Take the parts actually the whole saw would be best to a local machinist(with metal lathes,mills and grinders) they can reproduce or repair any of the parts on the vise or ways this isn't cheap but the best way to fix problems. I would check with them before taking it to one if they are a production shop they may not want to fool with it.You may also be able to find a guy with a home shop that will take a project like this. I would also have them check the arbour shaft and bearings while they are at it. It would amount to a complete restoration but you will have a very good saw that taken care of will last a life time.

Oh I wasn't talking about the actual rails... it is the thing at goes underneath and fastens it to the rail (a small flat metal thing) which has the job of anchoring it to the rails. Currently I don't have a budget that I can restore something, (trying to build a house this summer) or I would

Rockoonz My nelson is totally different from the highland parks saw... I looked at a video of how they adjusted it and I can't really compare my saw to that one I am fully aware of the different arbor setup, I have owned and repaired Nelson saws. The original place of manufacture is about 30 minutes from me. You really can't understand how the process shown in the manual (don't know about a video) is exactly what you need to do, except for using the setscrews on the arbor tube to make adjustments instead of moving a pillow block like on the HP? If this is true you need to find someone with a basic mechanical aptitude and pay them to make your saw work right before you ruin it.

Currently my set screws are frozen rusted... but there are 4 screws on the tube making me wonder if all of them are for arbor adjustment... I will have to see about the soft rock thing... The softest rock I know i have is 5 and is mud stone left over from doing something for a person.

Arbor is a tube inside of a tube so 4 screws is necessary. If you cut bookends you can use the top and bottom ones to set the blade 90 degrees to the base of the vice as well. Patience and lots of PB Blaster on those screws.

This (binding) sounds like the blade is at the end of its life, no diamonds on the side of the blade to keep a clearance in the cut. Or, as blades wear they tend to wear the cutting edge into a round shape, and the sides into a long taper, this can lead to binding but can be fixed by a bit of serious blade dressing to make the cutting edge square(ish) again. The blade could be dished, this happens from the tit left after the slab falls off running across one side of the blade, especially if you are running short of diamonds on the sides, turn the blade around occasionally to even this out.

Glenn good to hear it wasn't the ways you bent thanks for clarifying that would have been a very costly fix
