What is this?

[skeer]

Part number “DP-673” is stamped on one side but I can’t seem to find it online. Also tried search for ‘cast iron pipe clamp’ and ‘cast iron pipe coupler’. The latter was close but this has no rubber on the inside.
ID is 3.5”

High pressure and sanitary clamps come up in a search. Where is this used?

It's not a clamp it's looks like a collar. Looking through McMaster Carr it probably was used for hanging multiple pipes or conduit. Maybe not though if there is no threaded hole on the opposite side of the clamping side.

This is the part of my drill press that keeps the head in place. Or well more accurately, it supports the weight of the head but the DP 600 clamps itself the head does. So it’s on there I’m guessing kind of as a safety you know so the head doesn’t get loose for whatever reason and slide down.
I was looking for another one online because since the inside of that collar is more or less hollow like it’s not solid cast-iron, I can ground out a channel and have two collars, holding the gear rack that I’m making.

That makes it more clear. It is definitely a positive stop type collar.

could it be a casting number . Drill Press part # 673?

Yeah for some reason I did t think it was an OG part

I'm not at home but that appears to the stop collar for the table assembly. The head assembly on my DP is fixed so I don't know if there is supposed to be a collar for that too (if you have one that has a moveable head).

Supports the weight of the head? On my drill presses the head supports itself but there's a ring kinda like that to hold the teeth from moving that make the table go up and down (there's a crank to move the table).

The head clamps right.. well when I bought this the collar was secured below the head. Since the table is also clamped and is, for sake of argument, not adjustable. I assume the previous owner used it under the head as a ‘just in case’

 

[badguy]

I always figured it was there to allow swiveling of the head without having to support its weight manually. If your table swivels out of the way I’m not sure why you’d have to move the head without changing its height though.

Go to ebay and search drill press collar under 'used'.

They can be made of anything.. I had one that was 1/4 plate with pinch bolts brazed on... so long as the hole correct.

Some of my presses have safety collars under the head and the table. It makes it easy to loosen the head or table clamp and swing it to either side without having to hold it up before tightening again.

 

[Old Man Roger]

That’s probably the ring that holds the top of the rack that adjusts the table.

I have a very similar appearing clamp on my drill press. It holds the rack for the table elevation adjustment.
Mine came from Taiwan, and is broken.

 

[Old Man Roger]

Mine just keeps the rack from moving up, but it doesn’t clamp on the rack, it allows the rack to rotate with the table.

Pretty sure that’s what this is but since the tables more or less fixed, and the column not being the original (different OD I’m pretty sure) the previous owner moved this collar up to help support the head so as to not have to overtighten the head clamp and crack the cast iron.

I’m going to cut a notch in the inside lip of this one and use it to hold the bottom end of my rack.

 

[Old Man Roger]

Im a little confused, if you’re going through the trouble of making a rack, why not make the table adjustable instead of the head? Moving the table side to side and up and down will be easier than moving the head.

And if you want the head to rotate like the original table did, you want the rack to be able to rotate on the shaft, so notching that ring might not be a good idea.

 

[skeer]

I mean that’s an idea but the head already has the gear and handle and everything.
If I can luck into at least an empty table support then I’ll swap the gear, rack, handle and all to the table for sure. It’s the same part numbers for the pin, gear and handle.

 

[Old Man Roger]

Oh ya, I remember seeing that feature now that you mention it. What locks the head in place? I don’t remember seeing a pinch bolt?

 

[skeer]

Honestly.. I assumed it was the 4 bolts providing clamping force between the front/rear head casings on mine.. those with a working elevation crank I also assumed just the gearing tension itself. I have not notings or seen any other holes for a pinch bolt.

Hmm. I would like to see one in stock form to see how it works. Can’t imagine you would have to loosen the 4 bolts every time you wanted to make an adjustment.

I could see it if it was one of those multi head drill press setups. They usually have a workbench type table that doesn’t move.

Same, I’d like to see it as well. But I do struggle to find a reason why I’d need to swivel the head out of my way.

I guess you wouldn’t, I just move my table from side to side a lot because I have my cross vice bolted to it. If your vise is just clamped, you could always move the vise if needed.

I just wonder if yours is meant to be used without the head being clamped to the post. Can’t imagine it wouldn’t move if it wasn’t clamped.

 

[skeer]

Oh no i was talking about you mentioned moving your head like rotating it out of the way.
So on mine the only original parts on this is the head and that collar.

When the head is tight, the halves do not fully touch. I’m afraid is torquing it down until they do in case the back side cracks. Maybe that’s why the previous owner had the collar underneath, just in case.
My column measures 3.5” OD which I think is original sizing but.. that gap is concerning.

 

[Old Man Roger]

I would ignore the gap as long as the head is tight to the post. And the fact that the collar fits the post, it would seem to be the right size.

The collar is REAL snug. Like enough that I have to spread it open a bit with a flat head. Likely that’s normal.
