Hi,
John,
I had a couple of other photos that you had sent me at the
time that I thought might be of interest...

I have been advised by several digitalhobbyist forum members to place all relevant drawing information?in reference to the swinging tool holder in the digitalhobbyist files section.? This is what I will do in pdf format during this week. I do not want to share information with the 7 x mini lathe forum, but any serious 7 x mini lathe forum members are very welcome to join my group and hopefully they will gain more knowledge with a range of posts and hashtags covering most subjects that fit our particular?criteria and hobbies. Naturally all new member postings will need to be moderated a few times, no different to any other hundreds?of internet forums. But this was why I created the digitalhobbyist to allow access and share knowledge in this new digital age we are living in, and by sharing ideas and thoughts of some of the same "centuries" old questions, "how do we make the manufacturing?of support tooling etc etc in our tool sheds using basic?tools? "?
My swinging tool holder was based on the use of a 250-100 QCTP, so naturally a scaling?down for users of a 250-000 will be required on the dovetail block area and or scaling up or altering to suit each? user's choice of toolpost. I do not use a compound slide, but those that do then it should not affect the design. So back to the "drawing board" as they say, and now I am finishing off the tool holder dimensioning details making it an easy and fun tool to make for digitalhobbyist forum members. As a footnote the?swinging toolholder principle is not a new idea, I was?using them on Alfred Herbert capstan lathes and their?very ingenious automatic die heads back in 1970?s.?
Stay well and mostly be happy in your hobbies and interests. John

The brass "SAFETY" handle was used in the "cutting bottles'' work It applied pressure to the radial glass cutter by hand and left?all? limbs clear if the glass broke prematurely while ensuring there was 100% radial score line. A continual?radial lie was paramount?in ensuring that the bottles cleanly separated?after the? hot and cold water dunks. The weight of the swinging arm was not heavy enough to do this work alone, so there we go explained I hope. I guess it's where the saying come from,? "it just didn't cut it" LOL

That handle needs to be discussed, again.

I had wondered about the handle shown in some of the photos of the swing-up holder.? Clever!

I am more of a doer, and I take photos?as it helps me remeber what I have done.?
Most bottles used were empty from the local bars.
Must admit it was thirsty work so we did empty a few ourselves.

John, you could put the .pdf in the files here in digitalhobbyist files also. I do want them and if you do not mind I could post them to the mini lathe group. I have not been banned yet.

Hello Marc
I have read your post and can initially provide photos of both external and internal swinging tool holders
that I made several years ago.
I am currently writing an article for Home Shop machinist how I constructed this tooling.
Basically it?s a common tool holder and 2 x different blocks that slide into the QCTP Quick change tool holder.
The blocks are fitted with roller bearings and toolholders swing on a pivot pin entering these bearings.
As other projects have got in the way recently, I admit my written article has not got to far along.
In the meantime attaching some photos to give you some ideas of my tooling.
As a footnote, this tooling worked very well, in the past, but with the current use of the RELS with auto threading and auto retract of the tool,
this tooling has now for me become redundant.
If i can help you further let me know, I do have drawings available I can send in pdf format if needed.

Gday John
Have you considered starting a Youtube channel your brilliant work deserves a much wider audience.
Greg
PS you did not say who emptied all the bottles!

Hi John , Great tool could I have a copy of the drawings also. Cheers Allen

Hi John,
The roller bearings are a good idea.? Thank you for the offer of PDFs, but, since I'm using the Norman style QCTP, the design would have to be modified quite a bit.? Probably easier to roll my own, so to speak.

As a post with an interest in the swinging tool holder is current, I will include another use of this tool.            Short history, a friend of mine was building an outside BBQ plus bar. The bar support wall was built in concrete with the ends of wine and beer bottles placed in between the cement much like a stain glass window effect. The trick was how do we cut up to 100 plus bottle ends without numerous breakages and receiving serious damage to our hands from splintered glass. The answer at the time was the use of my swinging tool holder to score the circular score line pattern first. The bottles were held in a 7 x lathe using soft jaws, supported at the neck with a spring loaded revolving tailstock center. As?commercial bottles are not truly concentric, so by hand cranking them in a clockwise direction, a simple round glass cutter was put into? the swinging toolholder and pushed against the bottle to create the score line. The "swing" allowed a score line to be produced 360 degrees by applying gentle hand pressure on the tool, see photo of a handle on the tool holder. The arm of the swinging toolholder followed the eccentricity. also see the score line in a photo. Without the swinging holder but by using a conventional solid toolholder it was not possible due to the eccentricity of the bottles to have a 100% radial score. and dangers would be imminent, This would also be a real safety problem when splitting the bottle ends off in a second operation. read below. After this "scoring" of the bottles, it was a simple dip of the bottles just past the score line in a large bucket of boiling hot water using an external gas stove, then immediately the bottles were dipped into a bucket of ice water, this expansion and contraction of the glass severed the bottles at the score line, almost a 85% success rate, without serious cuts to hand and minimal fragments?of glass at the split line. See attached photos not in any order. Hope of interest. John -- John

Charlie suggested I post my question here as well as the 7x12 forum.? I'm thinking about making a swing-up tool holder to facilitate threading ops and am wondering if any folks here have made one, and, if so, if they have any "I'd do it differently next time" observations.
Thanks!

I would have thought you would need ER 40 collets, all ER holders have the same 8 deg or 16 degree inclusive tapers.
ER 40 will grip up to 25 mm dia, ER 32 20 mm dia.
Does your existing ER 32 collets clip into the ER 40 locking ring clip.
Cheers

John, Yes, my ER-32 collets fit into the mounting ring correctly. If you look at the series of photos that show the thread gauges, one of these shows an ER-32 collet mounted in the collet holder with the nut. As near as I can tell, it is a correct and proper fit. -- Regards, Charlie New Jersey, USA
