Drill press handle ‘hub’, how to remove from shaft?

[skeer]

Grabbed this feed wheel shaft and hub today at the junkyard. There’s no obvious set screws or pins. There is a single hole, it doesn’t go through to the opposite side, with what appears to be a pin. But I can’t drive it out, can’t see a set screw down inside either. But from the shaft side it’s def held onto the shaft by something.
Any ideas how to separate these two?

Drill press will usually have a key way or woodruff key. Probably a set screw in there, keep digging. Let it soak in something and blow it out. Worst case press it off and see.

I’m gonna bust out the mag glass and a pen light shortly.

#39.
Pretty sure that smaller hole contains or did contain a set screw.
The shaft probably has a flat on it and the hub probably has same. Set screws just holds it in place.
If you tried to Drive it out you may have flattened out the hex.
I would spray brake parts cleaner in the hole and blast it out.

ETA
If you find the setscrew is already out , I would apply some heat to it.
Hub is probably just Stuck on the shaft from years of gunk.
A little heat and tap with a dead blow.

That can be a set screw, a solid or hollow pin holding that on

best you can do is to get a description of part 39 from the diagram

Yeah it’s a hollow pin, and what I tried giving a few loving taps to was just the pin. Not whatever’s at the bottom of that hole.
I did heat it up last night but only to try to melt out the grease that might be up in the shaft side seam.
Have not tried to smacking around any yet. The drill press this came off of was a floor stander, generic Chinese model.. likely a HarborFreight (or a cheap knock off).

The shaft is the same size as my DP600 so I’m hoping to use this on it.

Couldn’t see much, the holes too tiny and my heads too big. The bottom of the side hole might be/used to be a hex set screw. I’ve tried every Allen that’ll fit and nothing bites.

It def appears to be a thin roll pin. But the hole doesn’t go totally through so.. why? You can’t drive it out.
I need to look again maybe there’s threads I’m not seeing last night.

To me, that looks like a 3/16" roll pin in a blind hole.

Get the largest drill bit that fits through the roll pin.
Drill through to the other side.
Using progressively larger bits from the other side, gradually enlarge the hole to 3/16" until you can punch out the roll pin.

Because it's not meant to be serviceable.

Drilling is probably your only option

Well sh!t.

Was afraid of this.. And I’m betting the shaft is hardened steel.

Post #9 is the needed method. Use a file corner across a point on the shaft. If the file bites metal it will drill with a normal drill.

I'm betting it's not. I've drilled through several old Craftsman pinion shafts with no problem.

Just go very slow with that small bit.

How deep is that hole through the roll pin? It may be through the pinion and ends in the hub on the other side.

+1 to the above post. Not likely the shaft is hardened, no need to spend the money on that. When you enlarge the hole from the opposite side you'll encounter the roll pin and that may booger up your drill bit so work slow when encountering it, an unpleasant sound will happen when you hit the roll pin. Good luck and use cutting oil.

Check the ID of the roll pin, perhaps you can tap it and pull it out.

Roll pins are usually somewhat hardened, but it's worth a try.
ETA- if the roll pin isn't too hard, it might be possible to drill it out with a suitable bit, maybe cobalt.

So I started drilling, and long story short I pulled the pin's leftovers out with a bit I thought was the same OD as the Pin was/is.

Some heat, some WD and percussive love and the hub fell off of the shaft. I think I got pretty lucky in this.. too bad my judgement was off on it fitting the DP600. I haven't measured things as I needed to get some job work done, but the handle end of the DP600's shaft is a small bit less in diameter than the hub.

You can likely find a real DP600 shaft on OWWM.org under BOYD (Bring Out Your Dead)

Assuming you have to register to even see that particular forum. I'll do the needful later and see what's what on there. I paid a grand total of $12 for this and the three handles.. I'll find a way to shim this and it'll be a great upgrade over the previous slot machine-style.

 

[skeer]

You got me thinking about the original, it bolts to the shaft from the end. I might not need a shim if I can drill a hole in the dead center of this hub.
Hmm

Sometimes you can thread a sheet metal screw inside the roll pin and pull it out enough to grab it

This,

Years ago one of my students doubled (stacked) the roll pin holding the internal shift block to the shift rail on his Borg Warner T-5. I told him I would give this a shot but I didn’t have much hope it would work. It worked amazingly well on both roll pins.

 

[skeer]

So here’s the result, enlarged the stepped down hole in the hub using a carbide burr. Just enough to mallet it onto the shaft and replaced the previous set screw with a longer bolt through the end.

Nice. I like those old well built machines.
