Mystery lathe items

[GraemeVW]

These were in with all the stuff I got today.
I half moon thing. Looks like it grips something as it's serrated. Probably one of 3? But I only have 1.

A, presumably, multi position carriage stop? For what?

And a mt2 adjustable thing

I'd guess as the MT2 thing being a fly cutter, possibly for use in a pillar drill rather than a lathe.

Yep, that could work.
Round cutting bits as its easier to make the holder?
Home made do you think? Not looked very closely tbh.

I'll take a pic of the other side, both sections can hold something I think.

A pilot bit then a guide in the centre hole and the cutter in the other. Round holes are easier to make at home than square ones. Oversized trilobular are even easier, especially in thin sheet metal.

 

[R Kraft]

Yeah, maybe a circle cutter

I'm good at them!

I'd say the more taper one is a trepanning tool (circular hole cutter), rather than a flycutter, as you'd need a threaded shaft for a flycutter.

I think your right. And you can get them for tailstocks. This looks a little light duty though.

The first thing is from a lantern toolpost. The tool sits atop it within the post.

Second probably is a stop, as you guess.

Ah, I have a lantern tool post in this job lot.
Thanks.

Yes, I wondered what for, but I think its home made.

Mystery handle too, 6" or 7" across.

Yes, the semi circular one looks like a boat from a tool holder.
Other one at the top does look like a stop especially if the knurled part allow you to rotate the bolts round.

 

[Hood]

Handle looks like the style that mills usually have, the wooden handle may not be original as normally they were chromed steel similar to the rest of it.

It will rotate, once it's been in the citric a while!

The handle looks original. Has a chrome base, it's plastic, not wood, and doesn't seem to be removable.

Makes sense a mill as you can disengage, or remove, that handles right? To stop them effecting the lead screw?
The screw must have had a pin sticking out the end, off center, that the handle locates on. Then also the bolt so you can lock it on more permanently if you want.

This is a trepan. The pilot goes in the end of the tapered shaft held by the grub screw and the cutter goes in the flying shaft also held by a grub screw. A very handy (but potentially very dodgy) tool in equal measure.

It looks very much like the lantern tool post clamp bridge that I have for my ancient circa 1942 Sphere lathe . I've kept the lamp post and bridge , but put a type two QCTP on it as it is much more stable as well as change over and start cutting again in a few seconds with no alignment needed . Once the tool holders are set they are good to go till the cutter gets re sharpened then it's a recheck for alignment and if needed , a micro adjustment for optimum cutting again .

The plastic handle could well be Bakelite plastic

It doesn't feel bakelite. Feels softer.

The tool post is missing is a square plate for underneath unfortunately.

I do like dodgy!
