- A good upgrade for the old Atlas drill press. I've been wanting to do this for awhile. I finally came across the material for a bracket and that's it. Sticking it to the man again!

MrBen527 as soon as you removed the front pulley cover I seen why you had an RPM problem. The step pulleys shouldn't have the large diameters in the same directions it should have one on the top side and the other should be on the bottom side. Look up step pulley calculator on the inter net and you will be able to figure out your rpms.
+toddlfrank You must not have seen the annotation in the beginning of the video. I mentioned that I had already flipped that pulley over to work with the intermediate one. Thanks for watching!!
dude be more positive and solve your problems with progressive & improved technology and leave cheap politics to burocrats
Thanks for this. Where can I get one of those brackets?
Very nice! Thanks, I have a Craftsman made by Atlas, and I need low speed too!
Now you know what to do.
That was awesome dude. I’d like to be able to make one for my old Rockwell. It was an option, but I’ve never seen one for sale, other than ones that were sold as 12 speed.
Now you've got a project!
Great! This is just what I need to do with my old Craftsman/Atlas. So what kind of bearing was in that housing? I'd like to do the same thing to avoid any permanent modifications to the press. I know I could make another motor mount and fab a jack shaft on the back with some pillow block bearings, but I feel like it'll throw the weight off by moving the motor off the center line.

That housing is off of a servo driven ball screw assembly.
thank you for your idea
im planning to use it not on my delta dp350 bench drill press but on my atlas clausen 60 inches bandsaw - that i just recently purchased for $75 from cl - if need it
my saw came without any pulleys, motor & blade
thank you
You're welcome!
sounds incredible, but my delta's reeve pulley shatered the driven reeve pulley - on the spindle in several pieces - and now im going into 2 simultaneouly steeper pulley projects. now im researching into the speeds for it. any how, your aproach into the steeper pulley system help me to understand some of its basic principles. im wondering if you have a video where you explain how to estimate speeds and pulley distance with driven belts - specially for drilling speeds with a drill press & a band saw. i understand that slower rpms are good for drilling steel and high rpms for drilling on wood. but, how does this works on a steeper pulley system? thank you
The step pulleys look more complicated than they are. Their design is to utilize as little space as possible and still get a variety of speed options. My drill press is on the smaller end which means made to work with small tooling at higher speeds. I added the third pulley to further slow it because I work with metal mainly and want options. As far as speeds, you could buy a inexpensive tachometer online, otherwise you'll need to know the speed of your motor first.
That's the perfect piece I need. Where did you get the bearing housing? I've got an old Craftsman 113.24560 with a 2.75" OD stand, and that would make my life r-e-e-e-l easy putting a jackshaft pulley on it...
It's a custom piece from my work place I replaced. I slit it and drilled it out for the clamping bolt. You could make one out of any heavy gauge material with twice the work I had to do with this part. You could purchase a 2.75 inch shaft collar from McMasterCarr for 23 bucks and start with that.
Thank you for making this episode. Very helpful. Wish I had one of those brackets. BTW, what model number is your Atlas?
Your welcome! Looks like it's a model 63-1M
@@MrBen527 Thank you for replying! I just found out mine is a model 73. Bought the stop assembly on eBay for $12.
@@SCWD_US Cool! This press was saved from a scrap yard shop that was closing. I had to replace the start capacitor on the motor and that was about it!
@@MrBen527 nice!
nice !
Thanks
you know you are running your pulleys 1 to 1 right? one of those step pulleys should be flipped.
and then i read the comments good work!
Thanks
If you live in a humid climate you might wanna slap some grease inside that bearing mount. It'll seaze to the column , trust me I know it will. I had to use a 3 jaw puller to get mine off.
Its good. I used sintered bronze bearings with grease.
It looks like the pulley on the motor is upside down! If you flip that over, and put the belt on the bottom of both pulleys it should put you at the lowest speed.
If you watch the whole vid with the annotation, you'll see I flip it.
Can you pls use two hands?
What now?
Wish you were selling the brackets. I'd love to buy one. Already have pulleys.
I don't know what materials I have laying around, I put of town now. If I remember and come up with a plan maybe I can make u one.
@@MrBen527 That would be fantastic! Thank you for considering it. Please let me know.
@@felixf5211 Will do
@@MrBen527 Also wanted to mention that I have a spare Delta 2.75" collar from a DP220. Not sure there's enough meat on it to tap for a pulley, though, but there might be.
@@felixf5211 I don't remember what size the Atlas is and I'm not home to check. As far as the one u have is just a matter of welding some material or a nut to it if it fits.
