I found a lathe for my son. A Taiwanese Cheng ki Industrial with 51/2" ch and about 28'' bc, seperate lead and feedscrew, Algra Rapidue QC toolpost and some other bits.
Amongst that lot is a QC toolpost. A type 100 "Boni" from Feldbach Switzerland(?) with one toolholder. It looks to be stainless(?); is anyone familiar with this brand?
I can post an image tomorrow.
Thanks
Here is his lathe..

Thanks dp. I was googling all last evening without any results, except a couple in Swiss:D . Maybe if I knew how to place those "tits' above the 'o' I may have had more luck.

A shop I work part time at has a QC tool post just like yours that was made in Italy. I can't find any info on it either. It's on a lathe much larger than yours.

The "tits" are the Umlaut. Since die Rechtschreibung (official rule book of spelling and grammar for High German) was changed recently it is now official that you may use the alternate spellings for words that contain Umlaut vowels. The Umlaut letters are ä, ö and ü. Instead of using the letter with Umlaut you may use ae, oe and ue as an alternate spelling since that approximates the pronounciation.

I think diphthongs are probably as much work to google as are umlauts :)

Thanks Evan, I will try to keep that in mind. I did a search using the 'oe' and hey presto!
It will be interesting to see what the holders are worth or cost($$$$). Perhaps those Chinese ones will do the job oldtiffie; are they branded?
I have a friend who is going over to his old country and Belgium next month. So if I do my homework and save real hard .....

It is fractionally larger than my Dickson by about 3mm; the finish and construct is better though.

Carld, the lathe in this post is my sons` and yes this toolpost would be overkill for that machine.

That's an interesting tool post...looks well made too. Do you have some pictures of the tool holder itself?

Hmmmm…from the pictures you posted it appears that the manufacturer figured out good way to keep 90% of the people from making their own tool holders for it!:D

Mike, here are some images of the toolholder.
Dp, the toolholder is drawn back and locked in position by way of the vertical eccentric shaft. If you want I can post an exploded image tomorrow.

Ken, I, too, have a 'Chinese' or similar tool post. Bought it in the UK at a Show. I suspect that you can get bits separately but mine came with three- including a parting off front tool. Now, I believe that you can buy holders with an extended overhang which is suitable for 'your Myford' as well.
I used mine on a 918 and then to my Myfords. I simply turned a sleeve to fit.

Norm

As an afterthought, one of your Kiwi experts produced his own very sophisticated set of goodies as well as the holder.
Not my way of working but Jack Radford had that unique quality. There are lots of other things in it but try:-

I have a friend who has one of these that he got when he got a new Myford lathe. I used it a bit. It is a beautifully machined piece, but I've got to say that I like the Aloris better.

Good Norm, my Myford is still amongst the 'to do' list. I have been accumulating accessories and extras for it though. I scratched my nads a tad too long rececntly and let a new S7 l/screw, half nuts and end support go. It was only $150 buy now but I had something else lined up at the time. I think that they would have retro`d .
Norm, I had/have that book by Mr Radford. I haven`t been able to find it since reading it back when Mum passed on.
Thanks for the effort oldtiffie. I will check out Chevpac and see what they have that may suffice. I am posting off an email to the Boni manufacturers, so we shall see what they have to say.
heavysteamer, I can`t say that I have ever used or seen an Aloris. They look tidy though.
The Boni is good for up to 200mm ch.

Hi Jay. I had been looking out for my son for some time. I chased up a couple of Hercus machines but I wasn`t happy with the mass of them. Then I spied this one, it was a good buy. Sold by the son of a deceased gentleman, one owner from new and well maintained.
Good centre height, 34mm up the spout, seperate f/l/screw and not too large for his shed.
It had a huge! gut busting DC motor and nice variac with it.

speedy,

Should you ever need titted Os again for a search,

Alt+153 (on the keypad, not main keyboard) = Ö

and Alt+148 = ö

Another more commonly used symbol is Alt+167 which = º (degrees).

Interesting toolpost - hadn't come across that one.

Franco,
Might I again suggest old Jack Radford's book?
I was looking at my copy again after finding the horrendous price of some( Mean Git, me)
I have four holders on mine but the even more irrascible Jack had at least 8.
All these were made at one sitting.

Radford was a remarkable engineer. This book also includes how he made a mill to fit his lathe, a tool post grinder, gear cutters.
He was almost a complete HSM under one green pair of covers!

G’day Ken.

Trust all is well on your side of the Tasman.

You mentioned it being Stainless early on. The pic to me looks to be of Nitrided steel.

Typical Swiss, good tool steel, finished, heat treated, then nitrided to give a glass hard surface.

That’s why it has that shinny surface.

Regards Phil.

Old Tiffie!
I am delighted and can assure you of some real quality information.
Your next 'conspirator' is the late GH Thomas who actually took some of Jack's drawings back to the UK. As an aside, I can just imagine the two pedantic old so and so's fighting it out.

If you have a Myford, you have no scaling to do but the drawings are very straightforward.

Let me know your views, please

I bought 2 of these posts in the eighties.

A famous brand name was then Rapid Fontana. It doesn't look they are still in business. But it looks like there is a kind of normalisation between the manufacturers.

I still have the documentation. The basic sizes are:

MK: sqr 50 mm
M: sqr 70 mm
AR: sqr 80 mm
A: sqr 100 mm
BR: sqr 115 mm
B: sqr 126 mm
C: sqr 145 mm

So you are probably looking for a holder type A.
Rapid Fontana also produced clamping holders for boring bars, morse cone holders and cutoff (?) holders.

On edit: I saw on one of your holder pictures stamped "100 A-n". So there is a relation.

Thanks Franko; I gave it a go and it works well doesn`t it? A good friend of mine lives up your way, he is a Pom and a real good bastard.
How are you doing there Phil? My initial thought was ss until I passed a magnet over it and checked out the Böni site that dp posted. It really is a nice unit. I used to nitride dies and other stuff from the toolroom years back and I don`t recall this finish. Thanks for the insight, it is appreciated.
I`m hoping for a response to my email from Böni in the next day or two.
No doubt I should be sitting or lying down when I get the price.
cheers all.

You don't know how lucky you are, mate. When I lived in Wellington you'd need to have an import license to get equipment like this. These days, I guess you can just go out and buy it. Thanks to David Lange?

Will your son now have a better lathe than you?

David Lange? Roger Douglas? Richard Prebble? Polititians=Sellout A`holes?

It is a fine lathe. Better? No it is just a tad smaller, it will do most all that mine will and he will never have to worry about relacement Colchester gears:eek:

Speedy,
the toolpost looks quite similar to the ones I have seen fitted to Graziano lathes in NZ. Except they have a name like "Rapid" or "Rapida" (can't check at present), probably like the ones MCS mentions. After many years of every day use, still like new because hardened steel. The only thing we replaced over the years were the screws. Unable to get square head, we used Unbrako capscrews, and welded up a new Tee-handle with a hex key to suit.

Speedy,



This would be a good tool post for someone to build. When I first saw it I thought it was fairly complex but it isn't. It has three independent tool holders that are clamped via their own small eccentric pushing a piston. Since the "piston" that clamps the tool holder is in a "box" type slide, no accurate vertical alignment would be possible. To fix this, the manufacturer put two "vees" on each side that force alignment. The hole in the center is just used for clamping the holder to the lathe's compound.

It appears that three tool holders can be put on at the same time. If they can, I wonder if it was intended to be used as a turret type holder. What do you think?

dp
06-29-2007, 02:57 AM
Mike - I think it's a CNC dream. The tool holders would be another thing entirely as a little error would produce some spectacular problems of fit. Still, as I watched the pictures come over the BBS it was pretty clear how to do this even without a plan. The symmetries are everywhere. And it looks good, too. Still - I'd make the first one out of birch :)

Peter, the lathe came with a Algra Rapidue toolpost and holders which is smaller and more suitable. The original t/post and the Böni came with it also.
On Saturday I got a reply from Böni with the price list. I have yet to see my travelling friend and this week I will sort out the freight $$ and search out the machinery dealers for any 2nd hand items.
The repeatability of these t/posts is said to be 0.01mm Mike. As a turret? I guess if the t/post was indexed to the compound it would be a go.
I have never fancied production runs though:)

Speaking of Fred Dagg, I see he is still going strong, thanks to YouTube http://www.youtube.com/watch?v=AYvMeT2GC14&feature=related. Non-Kiwi's won't understand a word of this, except for the Aussies who will get the drift.
