Need help identifying these
I got some tooling when I got my lathe that I'm not sure what they are. Hopefully someone has more of an idea than I do.
Pic 1: I have no idea. You turn the micrometer dial and it seems to limit the travel of the front piece vertically. The other small piece to the right of it may or may not belong to it.
Pic 2: No idea. It appears to be hardened and there's a bit of a hole in the tapered end.
Pic 3: My best guess is some sort of boring bar.
Pic 4: I assume this is for drilling. A chuck probably screws onto the threaded section. How/where would you use this?Peter

Pic 4 is a barrel clamp , never used one on a lathe but someone may have found a use for it as a quick action tail stock drilling device.
Pic 1 could be a mounting device for a dial test indicator for fine setting up of jobs in a four jaw chuck or on a face plate .
Three doesnt look lie any boring bar I've ever seen ,what the little gizmo in the RH end ? is it a through bolt ?

Hi Peter,
Can't help with pics 1,2 & 3, but pic 4 is a toggle clamp. When bolted down, it would be used to apply pressure to a work piece by folding the handle down. If the end of the shaft is threaded, it probably had a pad screwed on to it for fine adjustment.

Sorry I should have given a better description of some of these.
Woodlee. In pic 3, right hand end, are two 6mm square headed bolts that lead into a 9.5mm (3/8") dia hole about 12mm deep in the end. Left end has two through hole about 8mm dia. The left end is definitely for tommy bars. The right end I would say is for holding something round. Just looking at it I can see the ends are rough cut so I think this may be a piece of home made tooling for a specific job. Long tapping bar maybe.
Pic 1: The front bar is heavily spring loaded and will only move in an upwards direction. Turning the dial seems to only limit the upwards travel slightly. Because of the heavily loaded spring I don't think it's for holding an indicator. This ones had a few people scratching heads.
Pic 4: I got two of these when I got the lathe. Cleaned them up and they've just sat there because I didn't know what to do with them. I didn't think of clamping devices.Peter

Woodle: You could be right about Pic 1 being a dial indicator holder. I just sat down and had another good look at it. The micrometer dial when turned moves the head in and out. The screw on top adjusts the vertical height of the spring loaded flat piece on the right hand end. It's not clear in the pic but there's a hole on the flat bar just to the right of the top screw. The indicator could attach through this hole. Possibly!
Neksmerj: Can the clamp idea. Had a look and there's no way of locking the piston in position.Peter

No 2 - looked like it could be a tapered mandrel but then I ask myself why would it have a knurl on one end?
No 3 - looks like a boring bar of a sorts.
No 4 - looks like a toggle lock clamp used on jigs and fixtures at first glance, but given a second look it could be a minature tailstock of a sorts

Pic 2 looks like an alignment tool similar to those used to align the clutch plate on cars

Pic 4 I'm sure is a minature version of a tailstock lever feed. Toggle clamps look similar but this I believe is not one of those.

Pic 4 is definitely an over-centre toggle clamp. The handles can take many forms besides the one shown, and the links can also be arranged in other forms. Bases are also made in pressed metal. Cast versions like the one shown include several products by De-Sta-Co, such as TC-603, TC-607, TC-608, etc., as well as some economy clones.

I think you may be right. It does look like one of those. I got it with the lathe which threw me thinking it was something to do with that. I originally thought it may have been a knock out bar but it didn't go up the spindle bore far enough.
General consensus seems to be that Pic 4 is a toggle clamp. The model No. on it is T-110 which tends to go along the lines of what Joe has said. I can see now with the barrel fully extended it would lock but the locking range would be very limited. I could see how these would be useful in a jig type clamping situation but can't see much use in a home situation. Attached is another pic of the two of them. One fully extended and the other fully retracted. The threaded shank is 3/8" - 24tpi.
Footz since you correctly identified the 20 cent piece in the last pic I've replaced it with another mystery item. Just to test you out.Peter
