@@louis3141 Thanks for letting me know about the link. I found a comparable replacement: amzn.to/3wH0i2y . It's a little more expensive but appears to be the same. Look up the part number on Google image search and you'll see the picture. The one I used was a Westward Center Pulley Assembly, part number TT10409513A1G, but I can't find it in stock anywhere online now.
Nice work and a great idea. I did something similar a few years ago with an old Delta like yours and slowed my speed to around 300 RPM’s and I keep it there for everything I drill.
Thanks! I used a Westward center pulley assembly, part number TT10409513A1G, but it was eventually discontinued and became difficult to find. However, this same style of pulley assembly is used in almost every 3-pulley drill press. So, if you can find one on any of the replacement parts websites, it'd work.
Nice mod. You just made the same type setup of multiple speed drill presses. I have a 16 speed floor model drill press and that is how they get those lower speeds with that center pully setup. But be careful and watch the center setup for wear being you made it out of wood. If you ever get the ability, remake that center support setup at least out of aluminum. Thumbs Up!
Thanks! Yeah, hopefully those metal shaft collars will keep the wood from wearing out. You're right though, I could use the same technique by cutting the circles out of aluminum instead of wood. Thanks for watching!

Using those gloves while drilling you gonna regret loosing your fingers or your hand when the glove get caught by the drill bit, but it's good to show how to do one good thing and one not good thing.
Hmmm, It looks like that pulley might have been discontinued but I found a similar alternative on eBay: www.ebay.com/itm/153957843411 . Another option would be to buy the step pulley, bearings, and center post to assemble one yourself. Thanks for watching!
Thanks for the video. What would be good search terms for finding a pulley? "step pulley" leads mainly to 4-pulley assemblies. "double pulley" doesn't find many possibilities either.
I don’t see where you bought the actual pulley assembly. I’m looking to do the exact same thing and would be interested in knowing where and the cost of the assembly. Thanks……

I ordered that pulley thru the link and it doesn't include the bearing or the offset shaft. Only the step pulley showed up. Do you have any idea what happened there?

I installed the belt from the chuck pulley to the center pulley first. The center pulley has an offset shaft so that belt brought the pulley all the way forward and the size of the belt made it a tight fit. After that I installed the belt from motor pulley to the center pulley. Again, because of the size I made the belt, it was a tight fit. With two tight belts, the center pullet can swivel slightly to the left or right so the belt tensions will equalize, more or less. These adjustable belts stretch a tiny bit over time so, after they had been used for a while, I was able to remove 1 link from each belt.
The belts can be tightened by removing a link. These style of link v-belts can be purchased online or at stores like Harbor Freight. You could also adjust the motor mount for added tension which would tighten both belts since the center pully's post can swivel.
@@Mikeattempts Thanks a million for your answer. I have a 1940 Companion desk top drill press and I want to do the same thing you did. I’m wondering if the intermediate pulley system you bought would also fit mine. There’s really no difference between what I have, and an old Craftsman of the same year. I’d appreciate your thoughts……
@@Rstifleable I did a lot of shopping around before I bought that center pulley assembly. That's what led me to believe that most 4-step pullies made for drill presses were pretty much the same. So, if you could find a replacement intermediate pulley assembly for a Craftsman drill press, you should be able to make it work. Let me know how it goes! :)
If you watch the first 10 seconds of the video again, you'll see what I mean. When the black v-belt is on, the motor pulley has the smallest step at the bottom and the biggest step at the top. When the center pulley is added and the green belt is on, you'll notice that the motor pulley is now upside down with the smallest step at the top and the biggest step at the bottom.
Get yourself a 3 phase motor and a single phase to 3 phase converter VFD ( Variable Frequency Drive) it works much better. Great job on the center pulley 👍
And no gain in torque. Or does a VFD trade speed for torque the way gear reduction does, and I just don't understand it's process? I do know speed control on a DC motor lowers speed, but also lowers torque. I have a few servo motors. My Chinese lathe takes much better cuts with the AC motor and gear reduction that it ever did with the servo motor, and speed control. It was ice having speed readout on the led controller, but motor packed it in, ( shitty place to put a magnetic motor, under the chuck, where chips fall. Steel chips love magnets, and killed the motor. It waas almost dead when I bought, so knew I needed a replacement, reason for my great price) the induction motor is well away from lathe, is quiet, puts out a smooth HP at 1725, and is further reduced similar to this. I was fortunate to only need pillow blocks for lathe, and blunted to the bench, not the machine made it even easier. Now I'm doing drill press, and I know how I'm going to do so. Thank you sir.

Hi, Great video! The Amazon link for the pulley assembly wasn't working. Do you by chance know the model or item number? Thanks.

Nice work and a great idea. I did something similar a few years ago with an old Delta like yours and slowed my speed to around 300 RPM’s and I keep it there for everything I drill.
Thanks! I agree, the slower speed will work fine on pretty much anything.
I love this design. I've been wanting to find a way to put a jackshaft on my very old Delta drill press.
Thanks, I appreciate it!
Great project, thanks for sharing. I was way over thinking and over complicating this a got bogged down in my process.
Yeah, I had the same issue when first trying to figure out how I was gonna do it. I'm glad the video was helpful, thanks for the comment!
Thank you for sharing this I picked up a DP200 today and I think this is going on the to do list now.
Let me know how it turns out. Thanks for watching!
Was going to use VFD but like your idear
Thanks, it's definitely cheaper than a VFD. :)
1:19 Great video thks where do i buy the jack pully thks

Thought you were going to make the jakeshaft not just a mount
Sorry to disappoint, thanks for watching!
Great video, and perfect timing. I've been wanting to slow my press down.
Thanks, let me know how yours turns out!

He's got metal shaft collars, how will there be a problem?
Good video, where did you find (buy) the 4 step pull assembly.

Thanks Mike! I’m doing something very similar and this was super helpful
That's great to hear, thanks for the comment!

its a drill press not a table saw...cant be anxious about everything lil thing that can happen
Howdy, how is the belt alignment? Did you have to make any height adjustments with the intermediate pulley?
The alignment is good, I haven't had to make any adjustments.
Fabulous build... thanks for posting! The pulley assembly per your link is no longer available on Amazon. Any suggestions for a comparable item? Thx.

What do you mean by “flip the motor pulley” the pulley looks exactly the same as before on the motor or am I missing something?
If you watch the first 10 seconds of the video again, you'll see what I mean. When the black v-belt is on, the motor pulley has the smallest step at the bottom and the biggest step at the top. When the center pulley is added and the green belt is on, you'll notice that the motor pulley is now upside down with the smallest step at the top and the biggest step at the bottom.
Yes, you're missing your brain.
Brilliant!
Thanks for watching! :)
Get yourself a 3 phase motor and a single phase to 3 phase converter VFD ( Variable Frequency Drive) it works much better. Great job on the center pulley 👍
I considered that but I was trying to slow down the drill press without spending too much money. :) Thanks for watching!
Sure, for only 3 times as much money. What a useless suggestion.

I know this is an old video but buy a 1140 rpm motor at 1/2 HP for even slower drilling.
This setup has been working well for me, but I'll keep that in mind.
brilliant
Thanks for watching!
I did mine and got it down to 170rpms
Nice, that's pretty slow! You should be able to drill a 1 inch hole in some thick stainless steel at that speed.
