Went to a farm auction last Saturday and sitting in an old shed gathering dust and rust for maybe decades was an old Craftsman 3x6 horizontal band saw model 101.22922. $40 dollars and it's mine. Here's a picture from the auction website.

Got it home and promptly started tearing it apart. Forgot to take a before picture. Oops. Everything seemed to be working except for the feed cylinder. Just lots of dirt and surface rust. I oiled the bearings in the motor and it is purring like a warm kitten. Next I started cleaning the rust and dirt off of the stand. A few hours later and it got a coat of black rustoleum. Another coat tomorrow. This is a 50' paint job. Looks good from a distance. What can I say? It won't win any awards.

On to the feed cylinder. My first thought was that some of the O rings might need replacing because it was leaking fluid as I fiddled with it. Took it apart and cleaned everything inside and out. All of the O rings looked Ok. Back together, mounted on the saw and filled it up with fluid. No leaks and seems to be working property. That's it for today. Saw is just sitting on the stand for the pictures.

Nice score! I bought it's brother last week. 108.22920 is it's number. If you need tires for it let me know. I found a place that has 6 inch rubber tires. They came in today, but I haven't tried to put them on yet.

The paint job is definitely permanent. Put a 2nd coat on this morning. I don't plan to paint the stand again in my lifetime. Voca thanks for the heads up on the tires. Don't know if I need replacements. Haven't got that far yet.

Thanks. I bookmarked the site. My gear looks to be ok. I cleaned it up yesterday and it has all of it's teeth. Was out running errands today. Picked up some light grey paint for the saw. Cleaned all of the little parts yesterday. Very little rust. Just lots of caked on dirt and grime. Underneath all of the dirt and grime was light grayish green paint. Tomorrow I will clean up the two big pieces and get everything painted. Should have the saw back together by Friday. I have lots of steel to cut up for various projects.

It is all back together. Doesn't look too bad. I think that I have everything adjusted properly. One tooth broke off of the plastic bevel gear. Doesn't seem to affect the running of the saw. I probably need to replace the blade. Haven't tried to cut anything yet. That will be the true test.

Even with the old blade the saw cut fairly quickly through 1 1/4 square 1018. But the cuts are not even close to being straight. I cut oversize in anticipation of this. I will keep playing with the adjustments. I do not expect to get any kind of precision in the cuts.

Well I think that I am going backwards. Or at least not making much if any headway. I used my machinist square to square up the blade. That worked pretty good to square up the blade both vertical and horizontal.

I am running into 2 problems. Both might be caused by the saw blade. First the blade wants to slide down off of the guide rollers. In reading the owner's manual it states that this happens because the rollers are not tight enough against the blade. I have the rollers as tight as I can get them and the blade still gradually slides down off of the rollers as it makes a cut. The tension of the blade seems to factor into this. The other problem is that the blade sticks in the cut. This I think is caused by the blade being dull and old.

Suggestions please.

I got a new blade off of Ebay and the teeth are going the wrong direction. When looking at the new blade the teeth face to the right. On the old blade the teeth face to the left. There is nothing on the packaging that references the direction of the teeth. Did I just get a bad blade or am I missing something?

Since posting the above I have been looking at band saw blades and every picture I see looks like the the teeth face to the right. Are craftsman horizontal band saw blades odd balls?

See if you can grab the blade with gloves on on flip it inside out. That wasn't very clear. Not sure how to say it...

Or, you can put a foot down through the loop and then turn it inside out at the top of the loop. just tried it myself. works.

That works. Took no effort at all to flip the blade inside out. Now the teeth are pointed to the left and the saw cuts. Thank you, Thank you.

On to the next problem I am having. The blade guide rollers are held in place by a snap ring. As the rollers turn they put pressure on the snap ring and the snap ring pops out of the little groove that it sits in. Then works its way down the shaft until it eventually falls off. I have tried to clean up the groove. That didn't help. I am thinking about threading the shaft for a lock nut. Any other suggestions.

I'm having the same problem, hadn't thought of a solution other than replacing the snap rings.

I found the manual online and have downloaded it to my computer. I have been reviewing the parts diagram and the washers are different sizes and thicknesses on the outer rollers verses the inner rollers if that makes any sense. Also the outer rollers have a washer between the felt and the saw guide bracket that the inner rollers don't have. My problem is on the outer rollers. The guide roller shafts are the same. My outer guide roller shafts show evidence of galling. So I am swapping the inners to be outers to see if that makes any difference. My inner rollers appear to be all original. On the other hand the outer rollers have a mishmash of different size felts and washers. I wonder where I can get the felts. If getting the correct washers in the correct positions doesn't solve the problem then I will thread the shafts and put a lock nut on it.

That's where I am right now.

Might have solved the problem with the snap rings coming off. I picked up some 1/4" push nuts and pushed them onto the shaft. Did a couple of test cuts and all went well. Got a pretty straight cut too. Within what I would expect for a hacksaw.

McMaster sells heavy duty snap rings which should hold on a lot tighter.

Thanks for the suggestion to McMaster-Carr. The snap ring I would need is 1/4." The smallest MC heavy duty snap ring is 1/2." I think part of the problem with the snap rings is that the groove has worn allowing the snap ring to easily slip out of the groove.

The band saw is running and makes an ok cut. I like to oil my machines every time I use them. All of the oil points (wrong term??) are one of those little spring loaded balls that push down to let the oil flow down to where it needs to go. Only problem is no oil ever seems to go in. The oil just runs over the top. I tried cutting the tip of my oiler at an angle so the point could depress the ball. The tip will depress the ball but no oil seems to go in. I tried a point on a nail to hold the ball down and still no success.

What am I doing wrong? Or what do I need to be able to oil the band saw?

I've found ball oilers to be frustratingly difficult to actually get oil into until I switched over to precision needle bottles. I buy them from McMaster (https://www.mcmaster.com/1902t127-1902T47) and absolutely love them. You can push the ball in with the needle then squeeze the oil in. The small hole helps me not waste a ton of oil. The size I linked seems to be a good needle gauge for oils up to Vactra #2.

You oilers might be crusted up inside. In that case I would drill them out, clean the hole, and install a new one.

Finally got some wheels off of Ebay. Without the wheels it was very difficult to move the saw. Now it is a breeze to move it wherever I want it.

Happened to notice that the motor that came with the saw ran at 3450 rpm which I thought was high. In reading the manual the motor is supposed to run at 1725 rpm which gives a sfpm of 135. I have two drill presses. One is used for metal and the other is used only on wood. Their motors run at 1725 rpm. So I swapped the motor from the wood drill press. I didn't think that having a faster motor on the wood drill press would matter. I didn't swap the pulleys. I can adjust the speed of the band saw by changing which pulley I have the belt on. Currently it is on the smallest pulley which should give a sfpm of 90. I have also played around with the feed rate. Other than a faster cut I haven't noticed any difference with feed rate when cutting 1 1/4 x 2 1018 bar stock.
