Craftsman Drill Press for JZiggy

[JZiggy]

Picked up a factory multi-speed pulley.

The bearings are two stacked Norma 204-PP bearings which cross references to 6204.

I used a ball joint puller to get them off the shaft. It was hard work for this little puller.

Old vs. new Nachi sealed bearings

Why have an oversized vise if you can't use it as a press from time to time?

All together. Slight misalignment caused the corner to chip but no harm done.

This thing runs SMOOTH!!

 

[JZiggy]

I guess I'm a hopeless copycat. Sorry, FrankLee. One consolation -- it's actually a Delta base.

 

[JZiggy]

Yes it does work well. And it gives my tilt table a home in case I ever get sick of the big ol' production table.

 

[JZiggy]

The drill press is busy making slow speed attachments for other drill presses

Nice!!

That's awesome! Nice to see it doing production work. Is that aluminum plate tapped in order to mount the Vise?

 

[JZiggy]

Yes. I did not want to drill holes in the cast table.

I drilled and tapped and put in helicoil inserts.

 

[JZiggy]

Got the cross slide table set up.

 

[JZiggy]

Just throwing this out there... I picked up another one of these crank-handle table lifts. They work awesome for the smaller tables and rotate around the column with your table. I've only seen 3 of these in the wild and I was able to buy 2 of them. PM me if you're interested in one.

This was how my 1st one looked when I bought it. It shows pretty clearly how it works:

 

[nine4gmc]

That thing is awesome man! I wish I had some spare change, I'd pick that extra one up from you, hope it goes to a good home and they post up when they get it installed!

Oh btw, I saw a guy with one somewhere that had the 8' pole with that mounted at the top of the pole and the chain on the head so the head was adjustable height.

 

[JZiggy]

Interesting... I posted about the 8' pole in FrankLee's thread, sure you're not thinkin' of me?

 

[JZiggy]

Got two more pulleys assembled and ready to go. PM me if interested.

I saw it in person. It was used to lift the head, yours lifts the table, right?

Yes it lifts the table.

Nice Job, those look great! I'll be getting one from you at some point!

 

[JZiggy]

Thanks for the kind words!

Good job on these speed reducers - will forward to my friends who have these Craftsman Drill Presses.

A big shout out to JZiggy here!

I contacted him about making one of these pulleys for me and he came through.

Very good craftsmanship and well thought out!

I'm a very happy guy!!

Here's a photo of mine:

I'll admit up front here, I am just so tickled that this idea worked! I installed rubber vibration isolators (aka sandwich mounts -- think motor mounts) between the motor and the mount.

The motor is allowed to just gently bob along back there on its four rubber feet and essentially no vibration is transmitted into the press.

After installing the factory step pulley on my motor in place of the tiny 1.5" pulley I was using previously I noticed a significant increase in vibration. The pulley was balanced pretty well but not perfectly. I could feel a significant vibration in the table and the feed handle. Now that is totally gone.

 

[nine4gmc]

Awesome! Link belts help too.

[JZiggy]

Agreed, and the cogged belts also work pretty well. In this case I had vibration getting transferred even with the belt off.

 

[JZiggy]

I found a more period-specific Craftsman angle vise, judging by the stamped logo. Maybe one of the more knowledgeable members will be able to give me an approx year range?

This one was basically unused, still had the original varnish coating on many surfaces. After a quick degrease and regreasing it is very smooth.

I'm thinking that replacing the aluminum guide rails with steel of a slightly thicker gauge would be a worthy upgrade to this style of vise. If someone with milling / waterjet capabilities is interested in working on this with me shoot me a PM.

 

[JZiggy]

Just for giggles I picked up a late 60's Craftsman drill press for a little project to clean up and flip. This one came with a variable speed, reversible motor. It even had a handy chart taped to the side of the press.

I'm trying to decide if this would be a suitable motor for my press. It's certainly lighter construction than the big cast iron 1/2hp 1750rpm motor currently on there. My only worry is that the sub-2000 rpm range is for "intermittent use only." Why would that be? Too much heat dissipated through the rheostat?

 

[JZiggy]

I played with this motor on my drill press and it works well. But I decided to throw it up on eBay in favor of the original motor. Hopefully it will be a good upgrade for someone!

I put new bearings on a factory multi-speed pulley today. The original bearings were perfectly smooth but I wanted to throw some fresh ones on anyway.

One interesting thing I learned is that these two Norma bearings were both shielded on one side and open on the other, so the bearings effectively shared grease. Amazingly the grease was still in decent shape.

If anyone is interested in these bearings to overhaul a multi-speed pulley I'd be happy to send them to you. They just need a squirt of fresh grease. I figure someone might want to restore a pulley with factory original bearings rather than an Asian replacement.

Edit: bearings are claimed.

 

[JZiggy]

I think this is about my 10th pulley. They sure are fun to make. I hope folks are enjoying them!

 

[bagged89s10]

Nice work on your drill press and those pulleys!

 

[nine4gmc]

No doubt, awesome job!

Always interesting to see other slow-speed pulley designs, be they homemade or not. Here's an interesting one that showed up on eBay. Not sure what the make/model of this one is. Perhaps someone here can use it? The price is pretty reasonable for a multi-speed pulley.

 

[Cruzan80]

JZiggy, do you still happen to have either of those table lifts available? Would love to get one for my 150 drill press, or see about having one made from pictures.

 

[JZiggy]

I've got at least one lift in hibernation somewhere. PM me if you're interested please.

 

[Cruzan80]

Another question for JZiggy (and the masses):

I managed to get the collar and chuck off the shaft (threaded on, and just needed decent torque), but don't have anything that can fit inside the collar to remove the retaining washer-thingy so as to disassemble the chuck. Anyone do this before, and what did you use? Problem I am having is the angle needed along with the force.

 

[JZiggy]

Never taken the locking collar off the chuck. Looks pretty tricky to me too!

 

[JZiggy]

I love the big production table on my drill press, but it's awful heavy and overwhelms the stiffness of the column so the press will wobble sometimes. I have thought about bracing the bottom of the column or the table somehow and finally came up with a simple solution. I know you guys with mills and industrial drill presses will laugh, but it does work really well!

 

[bubinga]

cant he just "piggy Back" a ground wire to the cord, and just change the plug to a 3 prong plug?
I would not change the cord unless absolutely necessary. Once you open those old motors, the insulation on the internal wiring can start cracking and breaking. However, that may be reason enough to just remove the bottom motor cover and take a look.

 

[bubinga]

I mean, it won't look the greatest either.
You could also cut the wire going to the motor and bring your three wires into a box and have your switch in there too and just ground the ground wire to the motor outside of the motor and the frame of the drill press if that makes sense in other words you are bringing your wires into the box that house is your switch and breaking your hot there and continuing over to your original motor wires and then just piggyback a ground wire from that short section from the switch box to the motor and you could also ground the 3 prong wire 3 conductor wire I should say to the head of the drill press as well. Or if the Box is screwed directly to the head of the drill press just ground to the Box.

Rebuild another factory slow-speed pulley today. The Dake had to really try to get the factory bearings off. They are still in nice shape if someone is interested in them -- just need to be greased up.

 

[JZiggy]

Not really a drill press update, but I have had a couple of folks ask me about the slow speed pulleys and if I still make them. If you're looking for that please follow the link in my signature. Thanks!
