What is this?

[Dieselman 63]

I got a heap of gear today. In amongst it was this. I have no idea what it is. Any ideas?

A pulling set?

 

[minimutly]

Might be easier to answer if you got it all out?

A track setting tool for a Ransomes MG5 crawler?

I have one of these. It’s a rather disappointing piece of sheet metal! Looks a bit like a short tuning fork.

More photos. The M&W mic embedded in this bronze part is cool. But what is it for?

 

[Robotstar5]

Do the shaped plates with holes in fit on the pin of the bit with the mic on?.

The small one does but it’s only incidental that it does. No relation.

 

[Dieselman 63]

These bits go together. Still no idea!

 

[dobbslc]

Some kind of cable or wire tensioner?

 

[Dieselman 63]

These pieces hold cutters. They fit in this bronze piece.

This pin fits snugly in this yoke

I think it's some kind of setting tool. No idea what for.

Agreed.

In my head it looks aviation or large engine. Based on nothing. Just does!

 

[minimutly]

The setting tool and cutter holder look very similar to the perfecto setter for a van Norman boring bar. So I think the kit is part of a borer, cutter or similar machine. Quite a complex bit of kit though.

I reckon its an engine cylinder ridge cutter, or for cutting seats for stepped liners. I am pretty sure its designed to clamp down to an adjacent cylinder.

Yep, and those half moon things are what sits in the bottom of the adjacent cylinder, so the borer can clamp down. My guess is winona or van Norman made.

 

[dobbslc]

Van Norman = £££!

 

[Screwdriver]

Agreed.

Yep my first thought too. Aviation, hang the expense. I reckon when we find out what it is @dobbslc will be spot on: £££...

 

[dobbslc]

To be fair it was @minimutly said Van Norman first ^
I only know that their gear is expensive because I found a few cutters and other bits in an old workshop before it was demolished, I stuck it on eBay and got over £100 for a baccy tin full of bits
