Thread: Hardinge 5C Collet Brochure

Circa 1955. Illustrations from Holes, Contours and Surfaces, published by Moore Special Tool Company and an earlier Ebay offering.

I was just reading "Foundations of Mechanical Accuracy, and to my surprise and embarrassment Moore did flake quite a few of their surfaces.

Here's that chart:

[QUOTE=RayG;

The downside is I don't have gage blocks, so every job starts with making custom gage blocks. But for $8800, in the immortal words of Darryl Kerrigan.... "tell him he's dreaming..."

Hey Ray,

If pussy whisker perfection wasn't required could you get by with a shaper gauge miked to the correct dimension as a substitute for gauge blocks?

Looks like we're playing Snap!

I cannot recall if "Holes... has the chapter on how their good rotary tables were made. Foundations does ...It would make an interesting post.

Hi Greg/BT,
Do they give any reason as to why? seems silly to me to take a wonderfully flat plat e and machine 105(?) away. Its not like they are ways and need oil pockets.

+1 for the shaper gauge. Something else to add to the shopping list.

Stuart

p.s. thanks for the chart, makes sense now.

Hi Stuart...

I'll need to re-read either of those books again when I have more time. I'm guessing that they did it to enhance the bling factor? Oh! Maybe as tattle-tales to show if the surface is wearing? That's the only explanation I can conjure up right now.

I didn't want to get distracted as I am studying tonight for a simulator tomorrow night, but I did read that they made a unique worm gear lap for each table they produced. The lap was scrapped after one use.

Greg

Oh what the hell...

It's all explained in this PDF:

Hi Greg,
Thanks for that.
Back to study.

Stuart

p.s. and thanks for the pdf!

GQ,

If you are interested in posting the chapter I am interested in reading it.

The table was available in (I think) 3 grades of accuracy. A couple of weeks ago, an Ebay seller, "ReedsOlio" had a Moore Rotary Table Brochure on offer. Neat, though sadly not an abundance of pages and given the unlikelyhood of owning a Moore table, I let it go.

BT

Edit, Scanned and posted while I'm still struggling with the layout of the keyboard! Thank you Gregory.

The riken came with a complete set of the 20mm shank spring collets and the adapting collet sleeve to No4mt, I may chase some of the bigger No4 collets to allow me to grip up to 1"/25mm Max rather than 5/8"

I'm pretty sure that was the same one I saw, but from memory (it was prob 6-8 weeks ago now) he wouldnt post ouside germany, is there anyway around this? has anyone ever used one of those mail forwarding services?

You havent seen a faceplate for the dividing head on sale anywhere in your travels?
I've got the genuine riken one (serialised to all the other vices & attachments) which is pristine and I feel it would be a shame to drill holes etc in it (akin to killing a unicorn).

I have seen, fondled but not used a Centricator. I would have one simply because they are a thing of mechanical joy. Schaublin didn't offer one in their catalogues. They did list French made OPL optical micrometers so non native wasn't an issue. Singer had a number of Centricators for sale last time I looked. Have Heidenhain et al put an end to their use?

BT

The "thing of mechanical joy" point, probably carrys a certain amount of weight - But that is probably also the reason that we own the machines that we do.

The Centricator presenting the full clock face to the user is a handy feature and I feel (having looked at it and deduced rather than giving it a work out yet) with the range of probes/fingers etc included may more readily give access to confined and partially obsured surfaces but also as pointed out sacrifices a degree of sensitivitey over larger spans.
Apparently Gary and Des (the diamond tool holder bloke) sourced one for their Schaublins, and rate them highly for praticality of use. As you say, it wont be a genuine accesory.

Dro's have relegated a lot of "interesting" measuring solutions, trav-a-dial etc

I have some of those Deckel S20 collets too, but thought the MT4/MK4 ones would offer some advantages, like the 1" bore size. I bought some from RC Machines in Luxembourg...the same stuff that Singer sells for a lot less money. Also their are chinese ones sold by 800watt on US ebay...he'll ship here. You have to cut them down and make some thread adapters. Imperial only, but cheap.

I don't know that I've even seen a faceplate for the dividing head. I have a Zweibackenfuter (short back and sides, I think it means) 2 jaw chuck as well as the three jaw, but I would like a faceplate. Any chance of a picture?

I'd also like a larger chuck on a MT4 taper to bung into the horizontal spindle...handy for those large diameter turning jobs.

WRT to Germans unwilling to export: Its like pulling teeth with some of those guys. And also hard to get them to take Paypal even when I offer to pay their fees. Then they get cranky when their bank charges them to receive the wire transfer of funds that they insisted upon.

I have a friend's ancient mother's address in Germany, but for obvious reasons that's not for heavy items or to use too often. I'm not aware of any forwarding service in Germany, but would like one.

Greg (still reeling from the wire transfer reaming I got this morning from my bank)

I suppose it is the sort of thing that could be made fairly easily and tailored to requirements.
The split bushing on the underside of the faceplate is threaded to match the spindle nose of the dividing head. (45mm major dia for the male thread x 3.0mm pitch) Im not sure if the thread conforms to some German or Japanese standard as it wasnt one listed on the solitary chart I happened to consult, could be different for your Deckel dividing head.
Face plate 250 dia roughly 25mm thick (as its contoured), and there is about 50mm worth of the split bushing.
You can see the thread start must have coincided with a void in the casting, but quite nicely made. On the mill and accessories that jewelled finish on the machined surfaces features a fair bit.
