Bandsaw bearings/speed reduction?

[Everett_45]

Hey guys, I just bought a really nice Craftsman 10" bandsaw, model 103.0101. Supposedly made in the 40's, I wouldn't doubt it. Anyways, it needs some new 'blade stop' thrust bearings, the ones that contact the back of the blade to keep it in place. I'll have pictures below, but the bearing is a Nice No. 5852. I found it on RBC's website under a "600" series bearing, the exact one was a 601 with suffix 'V'. I couldn't find that number anywhere online. Do you guys know where I could find one online? Or could I just use a similar size sealed bearing as a substitute?

Part 2 of fixing up the saw, it spins way too fast for cutting steel (yeah yeah, not the greatest saw for steel). The motor spins at 1725 RPM, and with a strip of tape on the blade as a mark, it's far too fast to count as it goes by. Any ideas as far as gear reduction go?

Thanks in advace, pictures below

no comment on the guides, but Mr. Pete, aka Tubalcain on you tube did a series of videos on converting a wood cutting band saw to steel. his determination was that, unless you use a proper speed reduction box it isn't viable . worth watching IMO

Is this the one?

I did see that one, unfortunately the bore on that is 0.250" where mine is 0.275"

Consider an old Craftsman speed reducer. Model number 113.238961. I've had one on my bandsaw for years and it works great. They pop up for sale from time to time on the web. Here's some photos of my setup:

Many ways of doing this. Mine about as simple as can be - a jackshaft mounted on the motor- two different size pulleys, hinge motor mount with enough travel to easily pop the belt on the appropriate one. Far enough from the blade drive pulley an inch of belt misalignment is irrelevant.
I posted pix here somewhere; so have many others.

You may be able to fit a larger sheave on the saw itself to slow it down. However, if you're looking for a little project, why not find a free treadmill on Craigslist and use it to make your saw variable speed?

That speed reducer looks like it could work, do you cut steel with yours?

I have thought about a jackshaft, I'll have to draw something up and see if I could make it work.

It'd have to be almost 15" in diameter, which wouldn't fit due to the saw table. A treadmill is an awesome idea, that would be fun. Love the username lol, I'm about to start a millwright apprenticeship myself here soon

Around 150 to 200 linear feed per minute of blade travel works well for cutting metal. My large variable speed vertical saw ranges from 45 to 4500, and 200 is what I generally use.

The catalog shows that bearing as having .250" bore on one race and .275" on the other. Check your bearing to see if it's the same. You might've just measured the large race. And even if yours is .275 on both races it shouldn't take much to make that new one work.

Sure do. Takes a few minutes to swap out the blade.....other than that you just move the belt from the fast pulley to the slow pulley. The belt simply lifts on and off.

Take a look at this one, he seems to have it all worked out, cheaply.

That’s what I did

Nice video, but he is running it a bit fast for steel at around 280 fpm by my calculations.

I really like using DC Gear motors. Unfortunately the ones I was got recently would be great but they have too much gear reduction at 17rpm on the output shaft. Something around 37 to 50rpm would have been preferred.

Get a real metal cutting bandsaw.
