Delta Drill Press Broken drive pulley

Hey everyone, I'm trying to track down a pulley for a Delta Shopmaster DP350 Drill press and wondered if anyone here had any suggestions.

The main drive adjustable pulley is completely shattered and nobody seems to carry the replacement online anymore.

I bought a 5/8'' drive, 4.5' diameter v-belt pulley that seemed righthttp://www.northerntool.com/shop/tools/product_200576785_200576785, but its a hair too big for the shaft and wobbles even with the side set screw all the way in. Will this type of pulley even work since the one on it was adjustable?

Since 5/8'' is 15.8 mm, I figured my next move would be to order a 15mm bore pulley, but can't seem to find a metric size anywhere.

Any suggestions? Everything else still works great on it, so I'd hate to have a useless press because of one pulley. Some Pics are attached.

Whole top half shattered, bottom has deep crack

Edited to fix pics.

What do you mean adjustable pulley? Is it a Reeves drive? Variable speed?

Take a picture.

Also, buy good pulleys. Cheap pulleys are not balanced and as you learned, bad tolerances.

Edit: Yea, dude. That's variable speed. A normal pulley will ruin your rig. The adjustable pulleys open up and close down as you change the speed. You need an adjustable pulley.

Google "Reeves pulley "

Here is what he has........same problem here. I was thinking about making the upper section of that drive pulley, but haven't done anything with it yet. I found an old HF # 38142 16 speed that goes down to 200 RPM.....good enough for me.

Reeves pulleys are pretty expensive. Unless you find another Delta VS DP that has some other issue to use as a donor you'll spend more money than it is worth to fix yours.

Another thing, you can not adjust the speed without the thing running. As one pulley opens, the other closes, thus moving the belt in and out respectively. If you spin the speed adjust when not turning, it gets all haywire and doesn't know where the other pulley is.

well, sound like lilredex has BTDT, probably has the shirt too.
Lots O the same complaint on amazon as well.
It's a shame. You hear "Delta" You say, Oh yeah, That's a good one.
All that glitters isn't gold.
Can you get that front pulley to the largest position, and put a small(ish) pulley, on a treadmill Motor.
Only work around I can think of.
Or some middle of the road size pulley on that motor, and settle for single speed?
May I ask if you have very much $$ into the D/P?

Thats what I was attempting to do with the northern tool pulley, but maybe I just got one with bad tolerance? I'll try to get an exact measurement on the pulley. And I don't have anything in it, got it from a family member who was ditching it since he couldnt find a pulley to fit it :lol:

I saw that, but like you said below, no dice



Would it be worth it to get two step pulleys and then every time I need to change speeds just open up the top and move the belt?

Get one 3D printed
Then take it to someone that will do casting in the home shop. Machine to finish

Or just look on eBay , there ar people parting these drill presses out

Well that's good. Hopefully if that Co. Gets a supplier, they will use a better metal stock.

Usually the spindle pulley is an issue when trying to convert to step pulleys. What is the bore type on the front pulley?

Yes it might be worth it, but the front pulley might take to be splined, so the spindle can be driven, and also go up and down as it turns.
Unless it's did serene somehow.
Does that make sense?

Don't know if it would work, but I was going to cut out a disc of 16 or so gauge and push it through a ring (on a press) to get a funnel shape, after bolting back to back plugs in the center, to keep it going straight. Thought you might mount it on a lathe and do the metal spining trick to smooth out any irregularities, afterwards. Have not tried it, the whole project is on the back burner after finding that 16 speed HF DP, which is really better suited to my needs with that 200 RPM speed.

That HF DP came less motor and pulley. I have presently a 3/4 HP motor mounted on it with a four groove pulley (5/8" shaft) and it seems OK. The only thing I don't like is that the motor shaft is so short that the pulley only hangs on by a hair. I bought an 8" (Asian) DP to get the five groove spindle pulley. The bore is big and smooth (was held on by a set screw) so I intend to make a bushing/adaptor that will also extend the reach of that motor shaft..........let you know how it all works out.

The reason you are seeing DP 350's being parted out is becacuse they cannot find that pulley everybody is looking for. I would certainly not buy a used one, even if I found one. And I would not buy a newly minted one either, until it was proven to be superior to those original duds.

WOW!...a buddy of mine has two of the same drill press in his shop and just last week he asked me if I knew where he might find the very same pulley as he had already cannibalized a pulley from one machine for the other, then it finally failed! :mad:

I can't believe that Delta hasn't made these avaliable as it appears to be a MAJOR issue. I'm going to send a link of this thread to them and see if they respond. :thumbup:

Yeah, that will work - as long as you don't mind spending 10 times what a good drill press would cost. :lol_hitti

Yeah, they are too strict IMO
No off shore is one thing, No problem there,
But I mentioned In Passing, since I got a powermatic sander, I May restore the delta, and sell it.
Right away, I get a PM,

NO! Cause OF GD Auto Correct and My Ageing eyes.
Unless the spindle is driven externally and the splines are in another part,
That the pulley goes over, Driven By the pulley.

I've got a friend who's going to look at it and see if he can make something that will fit it.

Seems like everyone has the same problem! Definitely moves Delta to the back of the line for me when I'm buying new stuff. Do they support their new products or would I be out of luck with those too?

My pulley just shattered and spent the better part of today searching online only to find all of the stories of similar experience. I've also learned that it seems to be a part that is hard to find.

I found someone who can get it for you. Its not a perfect replacement (the outside diameter is a little smaller so you loose some top end speed). He indicated I can share their contact info so I hope any of you looking for a DP250 or a DP350 motor pulley are going to be in luck.

That was then....much has changed in the following six years as you'll see if you read all the posts. They are nowhere to be found now.

Maybe that Grizzly pulley will work......if I can get the dimensions, and another possibility is on a Jet JWL 1236 lathe. You can see that pulley in action here.


Anyone have dimensions for that one?

EDIT: Here are the pulley dimensions for that Jet pulley. 105MM OD, 16MM bore.

Will get out to check mine when it gets warmer around here.

For the record, that elusive drive pulley for a Delta DP 350 is...

4 1/2" diameter and fits on a 15 MM drive motor shaft. The belt used is 1/2" wide.

No problem. I just went out & measured it.

Pulley is just about 4-1/2", mine was 4.45" to be exact. Motor shaft is 14mm though. But looks like there's plenty of room to bore it out to 15mm. Not sure if you have access to a lathe. If you were closer I could do it for you. But again mine uses a 10mm/3/8" wide belt.

Ordering parts from Wen is actually pretty stress free. Their prices are pretty cheap as well as their shipping costs. They have pretty much everything in stock in IL. They shipped quick. And the person who took my order was very knowledgable about the parts/machines. Even was nice enough to recommend me some good Chicago food near where I live. I'm not affiliated with Wen/GLT or anything like that, just sharing my experience which surprised me.

To give you an idea. Here's the drive pulleys for the 10". I'm not sure if it's the same but the 10" has the same speed ranges as the 12". Regardless give them a call if you want to try ordering one for the 4214. They don't list all their replacement parts on their website. This is just an example of their pricing.

https://wenproducts.com/products/4212b-016-motor-movable-pulley?_pos=14&_sid=3b05422a4&_ss=r

If you do order one, I'd love to hear if it works out for you.

Measure the shafts and replace both pulleys with step pulleys. Worst case is that the shafts are worn. In that case you will need bearing sleeves. Your local bearing supplier can help you with that.

Here's an idea. I did it on mine.

I got a treadmill of craigslist/facebook and put the motor on the drill press. I used a small pulley on the motor and the big pulley on the spindle. The controller screwed to the side of the housing with the dial right on the front. Variable speed, full torque, and it goes fast enough to route/grind. Mine looks kind of pokey, but it works great.
