Tool identification help please.

[GeorgeS]

So I'm digging through the box of miscellaneous stuff that came with the 3520B I just purchased and there are a few things in here that I'm not sure what they belong to or with and was Hoping you guys could help me out. Here they are. I was also surprised by the tools this gentleman was using. Lots of Pittsburg and a bunch of home made stuff.

So this thread doesn't fit anything else I received with the lathe. No clue what it went with. Wondering if I should mail it back to the guy who handled the sale.

These appear to be drive centers but have no taper on them. One has a flat ground on the profile and the other has some recesses drilled into it but they also do not fit anything else I have.



This faceplate doesn't have threads and I don't think I would ever use it. Also doesn't fit anything else in the box.

Thanks in advance!

Sorry about the typo in the title, can't fix it!

The cone is for a live center. Check if you have one with threads on it.

 

[GeorgeS]

I didn't see anything with threads but I will check again.

George, the machine has 2 "arms", one on the head stock and one on the tail stock, where you can mount a completed spindle (say a table leg) to use as a pattern to duplicate. The 2 centers mount in the arms to hold this comparison piece.

Winner winner chicken dinner! So he has a live center that the cone comes unscrewed and this will screw on in its place. My question is what is the purpose. Would it fit say in the mouth of a hollow form? Thanks Colin!

See, I knew you guys are awesome! That makes perfect sense, I'll check that out. Thanks Tom

Depends on what the other side looks like. If it's a hollow cone, then screwing it on so it flares outwards towards the headstock can help keep round end spindles centered (for example, a newel post for a stairs banister) when you want to avoid making a hole in the end.

If you screw it on so the narrow end is towards the headstock, then it's exactly what you said -- fits into the mouth of a hollow form.

 

[GeorgeS]

@duncsuss Thank you sir! I am learning a bunch today!

 

[Tim Carter]

The cone with threads looks like it's from a One Way live center set.

 

[GeorgeS]

Yes sir it is.

Going to preface this by saying I have no idea what I'm talking about but that last picture looks like one of those things you screw to as bowl blank before throwing it on the chuck. Maybe the hole in the small end is there for a wing nut to grab onto? Again, I have very little lathe knowledge.

 

[Schroedc]

Looking at some of the stuff I've got I wonder if that face plate was made to slide onto a live center of some sort to support something. I've got a couple flat plates made for one of my centers..

 

[duncsuss]

That last face plate ... what's the internal diameter of the hole? If it's 5/8", then that will fit onto the drive shaft of a Shopsmith (and a 1942 Sears Roebuck "Dunlap" lathe). The drive spindles are 5/8" diameter with a flat ground on one side, which the grub-screw tightens against to stop the whole thing spinning freely instead of driving.

(The 1942 Dunlap was a gift from a co-worker, my first lathe and the first step into this vortex ... )

 

[GeorgeS]

@duncsuss I will check on the diameter of the hole. You are probably right in assuming it came off something else.

I also have three small round bar tools that I found inside the tail stock that I'm not sure what they go to. I printed out the manual last night and found the cone and live center info but don't see these in the parts list anywhere. Ill put up a picture later but they are about 5" long maybe 1/4" in diameter and have a red rubber coating on the handle. Just a round bar with no flat or any kind of end to it so to speak. They don't appear to fit the lathe either that I can tell.

Those sound like tommy bars for tightening a chuck I have a couple chucks that use those instead of a chuck key or allen wrench

Yes, sounds exactly like the ones I have with my PennState "utility chuck" and the collet chuck from CraftSuppliesUSA. Here's the PennState photo of their chuck:

 

[Tom Smart]

Some larger faceplates, like Oneway, come with bars like that for loosening it from the headstock.

 

[GeorgeS]

Here it is, I have three of them.

Yep, those are Tommy bars. Used to tighten chucks or loosen faceplates.

 

[GeorgeS]

So you use them as leverage between two jaws to twist the chuck loose?
