Swing up tool holder?

#MISC #LATHES #MODS

Mark Kimball All Messages By This Member #1421 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! Mark
John Lindo All Messages By This Member #1422 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. -- John
Mark Kimball All Messages By This Member #1424 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. -Mark

Jonathan Mackenzie #1427 Would love to have a copy of your pdf in the files section of the MiniLathes group ( /g/Mini-Lathes/ ) - we are building out a good library of plans there.

Ralph Hulslander All Messages By This Member #1428 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.

John Lindo All Messages By This Member #1430 I will post the pdf files of the swinging tool holder into digitalhobbyist later this week. Thanks for all of your interest.

John Lindo All Messages By This Member #1435 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.

Ralph Hulslander All Messages By This Member #1437 Thanks John, the motorized Z drive system I am close to implementing AtomicELS?does not have a X component. So the swinging?tool holder is high on my list. I hope to modify AtomicELS for X but that would require a lot of help from my friends. Once I get motorized X I will install RELS. I'd also like to try some of the newer versions from Oleg's ELS. Ralph toggle quoted message Show quoted text On Tue, Apr 6, 2021 at 12:54 PM mike allen <animal@...> wrote: ??? ???

John Lindo All Messages By This Member #1439 I have added two files in the Files section. Generic dimensioning as each? lathe and toolost holder will be different I useed a 626Z bearing. Any extra info required then please post. -- John
