Nice score Bob

Another good day at the Bendigo swap.
Picked up a really nice Sip rotary table. Should be big enough for most jobs I can think of.
A box of grinding wheels which came with a bunch of arbours that I'm not sure what they suit, they have a short taper with a keyway. Anyone have any clues to where I can find out what they fit?

Your meant to say " that's not a rotary table THIS is a rotary table........"

Nice score. Hopefully it cleans up alright. Can't stand good gear like that being neglected

Cheers Piers

Sip rotary table
Bet it squashes your mill flat when you load it ... )

I had a taiwanese tool and cutter that had those same arbours, sorry I don't recall the make

This proving ring lurks in its (oak?) box in my shed, it comes to the surface occasionally when I'm moving stuff around. I bought it because it was cool and local to me in the early 2000s when the University of Queensland Civil Engineering Dept was having a clearout of unused gear. The story was that UQ bought the ring in the 70s, paid many thousands of dollars for it and never used it. It was unboxed for the first time to take photos for its sale on eBay.

The system for measuring load is interesting. There is a large scale micrometer mounted on the bottom of the ring and a vibrating reed which hangs from the top, measurements are taken when the micrometer tip stops the reed from vibrating. I'm not sure if load is read directly from the micrometer or if you refer to a table of deflections, I suspect the latter.

I'm never going to use this proving ring for its intended purpose, if someone can put it to use please PM me.

Alright, Bob,
I will bite. What does it do?
That is, apart from being shiny and attracting bowerbirds like me.

Grahame

Use it for a tramming ring on the mill?????
Kryn

Yes its shiny and beautifully made and very attractive. Its used to determine the quantum of heavy loads, i.e. zero the ring in its relaxed state, load the ring, measure the deflection, determine the load. Think of it as an analogue load cell.
The Morehouse company still exists and the proving rings are still made but the mechanical measuring system has been replaced with a digital system. Which, thinking about it, could probably be done to my ring.

If nothing else it could probably be turned into an interesting base for a glass topped occasional table.
Using a ring like that is (or was at least) a reasonably common engineering practice as rings are easy to produce accurately and their behavior over small deflections is known pretty darn well.

Not at my place. Her indoors likes to re-arrange the furniture far too often.We don't have a forklift.

Grahame

Bob its a wee smaller

Hi Bob
I might have a use for it and have sent you a PM.
Cheers

Here are some extra photos of that die filer, i went back and purchased some other items from the previous owner Also, a Japanese NEWS dividing head and a tiny deckel rotary chuck, i think originally off a pantograph20171213_134754.jpg20171213_134739.jpg20171213_134728.jpg20171222_203713.jpg20171222_203647.jpg20171222_203656.jpg

Apologies for none of those being the right way up but i can't fix them on the phone.

Nice score. The FD rotary table is off a pantograph. Stefan Gotteswinter made a set of outside jaws for his one. Great use of a pantograph.

What size is you News dividing head? I picked up a NEWS BS O size which has a Brown and Sharp tapper in the nose. A guy on PM had made an ER32 collet chuck with the B&S tapper so I got one of those.

Mine came with a manual if you would like a copy.
