Delta Dp350 Drill Press Replacement Parts

Guys,At a recent machine auction I bought a pretty large, industrial duty Delta drill press. 'Large' being a relative term, by that I mean 'way more robust than the cheap Chinese press it will replace.

It was in an industrial setting and has a 460V / 230V 3 phase, 1 HP motor. So, I guess you'd say it's a 'medium size' machine. Still, it weighs at least a few hundred pounds.Anyway, it came with no chuck. Would somebody hazard a guess as to what the most common, and second most common drill press tapers are? I seem to remember its MT but don't remember the number.I would like to find a chuck for it.Thanks,V.

Guys,Thanks for responding. The quill (if that's the name for it) has a tapered hole in it. The machine is a 17-760 (17') Delta industrial drill press. I don't know its age but it could easily be 20 years old or even 40.I happened to have a MT2 live center from a lathe I bought at the same time as the drill so I tried it. I would say that it 'almost' fit.

It was too small but it did not feel as if it was going to disappear. So MT3 might be right? I have a couple of Chinese drill presses but don't remember what size they are. They're certainly much smaller machines than this one.Is there a way to measure this? I hate to squander $100 or more on a chuck and it be the wrong critter.ThanksV. Bill,Thanks a lot for your link to the different morse taper specifications.However, I'm somewhat confused. Going from memory, the table says that MT-2 is about.70' and MT-3 is about.9375 (those are not exact!)Whatever the measurement for MT-3 was said to be I calculated that it was about 15/16'.A little while ago, I went in to where the drill is standing.

Rather than try to crane my head down and look up inside there, I took a square of masking tape and covered the hole with it. I sort of smooshed the inner edge around with my fingers and then peeled the tape off. There was a faint rust ring, which I then proceed to measure (.' If you want a job done right give it to a lazy man!).The result, measured with a carpenter's tape measure, was approximately 13/16. That's about one tenth of an inch bigger than MT-2 and appears to be about 1/8' smaller than MT-3.You mentioned something to the effect of 'a jacob's chuck that side would have it's own spindle' and suggested that I replace the spindle in the quill.First, I'm not sure I understand the difference between 'spindle' and 'quill'.

I believe the quill is the 'pipe' that moves up and down but doesn't spin and 'spindle is the inner part that does?What I've got is a hollow tube coming out of the drill press head. It has a long longitudinal slit in it. There is a wedge shaped tool dangling from the table.

I sort of imagine this is the tool used to drive into the slot thus causing the chuck to come loose from the drill. Yes?Am I missing something?Vernon. Out of the clear blue I just had this epiphany. Assuming I took a good measurement of the inside bore of the spindle (approx.

13/16') and if indeed the MT-3 large end diameter is 13/16' could it be that my critter is indeed MT-3 and that the arbor simply does not go all the way inside the hole? In other words sticks out just a wee tad?

If so then it makes sense to me.I took a peek at the ebay picture for which I thank you. If the taper goes up inside the spindle then how do you affix the chuck to the short stub?

Is it tapered too? In the picture it appears to be a straight shoulder.By the way, I have a couple of Chinese drill presses although they're much much smaller. I decided it would be good to knock the chuck out of one to try it in the Delta.When I rapped it with a brass punch the chuck came off of what looked like a downward pointing taper.

The rest of the piece (the arbor?) is still inside the spindle. In fact it looks like it might be threaded in although it was dark in the room and I couldn't see very well.Talk about comparing apples to oranges. Or better put 'chicken s. and chicken salad'.V. 'PS: your dp may be a rebadged Walker turner.' This press is either a 17-430 or 17-460. The next to last digit is wonky and I can't read it.I went to a site that has Delta catalogs.

They list both the 17-430 and the 17-460. However, oddly, all of those models that end in 'zero' show to have been shipped without the motor. I don't understand what that's all about.

Delta Dp350 Drill Press Review

The brochure just gives the weight of the head only and very little other info as to the 430 or the 460 or any of the models that end in '0'.VP.S. Here is a picture of the old girl.

Would not surprise me that the taper part would stick out a little above flush. On small dp there may not be a morse taper at all.

Just the male JT sticking out. Allows the spindle to be smaller/cheaper/ lighter. Sometimes used on small usa made ones as well. On electric drills the spindle is now most likely threaded with a screw on chuck.My brother has a older Millwaukee that has a JT spindle on it. He could not find a chuck for it,cheaply, and had to buy a rare key to use the chuck that came with it.Bill D.Link shows the slot that may be in your quill to drive out old tapered arbor.below are wedges that are not what you need. Keep in mind, while the common Morse tapers used in lathe headstock and tailstock spindles are a clear standard, the length, starting and ending diameter are less predictable.

An MT drill bit is a useful reference, but a shorter piece of MT tooling that came with a lathe might be missing the long end, or short end, and so is harder to use as a quick check when stuck in a full-length socket.We have a couple of the older 17-600's, one has a male JT33 spindle nose and the other has a female MT2 socket.The '33 has the integral threaded locking collar, that serves both to lock the taper in place, and also to push the tool off, as an alternative to a wedge. It usually has a 1/2' Jacobs chuck on the JT33 - model '34-33C', and it also has adapters that convert the JT to MT2 and MT1 sockets.MT3 is pretty large for what is still a light duty drill press. Nice drill press though, esp.

The large square table.

Hey guys,I have a Delta Shopmaster DP-350 12' drill press. I wish to replace the stock belt with the twist belt that I am now so in love with. However, upon opening the housing I think this belt is not a 'V' belt. It has teeth in it. Part of me thinks the twist belts will work fine, but part of me also thinks that it will not work.As I change speed the assembly appears to change the length of the belt. I think it is just an illusion. One side increases in diameter while the other decreases.Does anyone have a machine with a similar assembly that has installed these power twist belts.?I referred to my manual, but they do not even tell you how to change the belt let alone if this twist belt will work.Thanx,shotgunn.

I considered using a twist belt in mine, but decided to leave well enough alone.The length of the belt does not change, the diameters of the pulleys do.To change the belt, take the top of the rear pulley off. Do it with the DP set for the highest speed. Remove the C clip on the top of the shaft. Be careful, the spring is under tension. Take the top of the pulley off, change the belt.Now you have to replace the pulley half. Put the spring in a vise and squeeze it closed. Use a couple wire zip ties to keep it compressed.

After you get it all put back together, cut the ties.While you have it apart look at the split pin in the top half of the pulley. If it looks to be coming out, wrap a wire tie around it and tighten it.
