I'm checking out a used Delta band saw this weekend. What should I be looking for to know it's in decent shape?

 

Model #52-941. $350. Looks like it's in pretty good shape from the potato pics.

 

 


If I'm reading the SN right, it was made in 2002. Plate says made in USA.

Bearings and shafts


Tips for evaluating that? How should I test those things?

Upper and lower wheels move smoothly with no wobble.

Look for slop in the bearings by grabbing hold of the wheel and twisting.

As the other's said, main wheel bearings both top and bottom.  

 

Also, what type of blade guide does it have?  Some are roller bearing and some are composite blocks that pinch the blade.  These you'll find on the arm that goes up and down that determines the throat opening for your material thickness.

 

If they are the blocks, that's an OK system.  They make replacement blocks out of silicon now that are called cool blocks.  Worth the $10 upgrade to that.  If it's bearings, make those are free spinning and not seized up.

 

The other wear item is the rubber belts on the 2 drive wheels.  They can dry out and crack.

I checked it out. It runs smooths. Vibration seemed fine. The wheels turn smooth by hand. I wiggled them and they seem solid.

He offered to drop it off which is a bonus since I don't have a pick up or trailer. Probably going to pull the trigger. If so, I'll post more detailed photos for any tips on mods/repairs and whether I got a good deal. :)

$350 is not a bad price for a saw that size.  Band saws are either hardly used....or used a lot.  As long as it wasn't neglected, I'm sure it's worth it.

OK, so this hunk of iron has a new home. I did a little cleaning and tune up. Pretty much disassembled a bunch of it, knocked off rust, lubed, and put it back together. Learned a bit about how bandsaws work.

 

I think it got banged around in transit. I got it purring pretty good, although sometimes it a little noisy. I'm going to get a new blade before fretting over fine tuning. It's working well though. I'll tinker with it to clean it up more and see how much rust I can get off of it. If I feel like it, I may look for some parts.

 

One issue is the lower adjustment area. I can't move the blocks with the adjustment screw. I need to tap them over. They were frozen, but I got them to move now with a little encouragement. Also, that bearing stop down there is loose to set up. Seems to hold though with some messing around.

 

This set is how it looked before some TLC. Second set was when I called it an afternoon and put it into the shop.

Here's a shot of the lower area. 

 

The whole deal moves laterally to align the blade in the guides. That's still pretty stiff after scrubbing down, but can knock it over with some taps from a wrench. The lower bolt is supposed to move that, IIRC. It only screws so far, then won't budge.

 

The upper bolt controls the bearing behind the blade. That's pretty loose, but got it set. I wouldn't be surprised though if it falls out of alignment after some sawing. 

 

The rest of the adjustment points seems solid.

Pretty sure that's the exact band saw we had in my junior high shop class
