seems there would be a clearance issue with the vertical chuck hitting the horizontal one.
Nice build and finish again! Congrats.
Feedback point: -It would be most helpful to fellow HMT:ers, if you took a few seconds
showing how it works and how you made it, not merely showing it off from 4 different angles.

Machining 4 All,
Nice looking work, but a mini lathe or any screw cutting lathe equipped with an auxiliary spindle is already capable of milling threads and will do the same work without modifications. This modification seems like a lot of work with little corresponding benefit.
This is just my personal observation.
This device was built to help me with other projects. Thank you for your interest!
This is a photo of my first machining test with this device. The idea would be to make a second complete video, showing other details and applications. However, "experts" on this forum have already condemned this device in advance. Rest assured, I no longer intend to occupy you with my bad ideas...

Please don't give up. I'd love to see the potential of it. Thanks for posting it. I'd also be interested to see how it's made.
Machining 4 all; The only bad ideas are the ones in which an injury to a person occurs, everything else is and has a variable amount of usefulness.
Just because there is already machine which is capable of doing something doesn't necessarily mean everyone owns one or wants to buy one.
That being said I have a couple of questions about your device.
#1 do you have an indexing feature on it? I noticed in the photo of the job you are incorporating it on has multiple starts for the helix groves.
#2 Do you change the thread pitch by swapping out gear combinations?
#3 what would be the minimum useful TPI or MM per thread reasonably achievable?
#4 By the way I like your idea for the device
Thanks for the interest Floradawg and Frank S! Unfortunately, some of our "experts" on this forum are very good at criticizing, however, they haven't had any more projects since the 1940s. It is not the first time that they have done this with me and other collaborators in this forum! This thread is dead to me, feel free to remove your thanks!
"Only criticize a project if you have a better one to present!"

You ought to try talking with gun guys online. They are the worst. They love to rip newbies a new one for not knowing as much as they know, for being...well, newbies. I've also seen this in a shooting range I used to use. The guy in charge that day which I already knew, was full of himself. He thought he was the MAN. This young guy wanted to rent a Glock and shoot it with his girlfriend. The guy in charge asked him all sorts of stuff about which "model" of gun he wanted. He was purposely embarrassing this guy in front of his girlfriend. No I was not mistaking his intent. It was very obvious. Okay so all you gun guys, I am one of you and may be opening a can of worms here. I'm not trying to. Just telling what I have seen. It happens in lots of different forums, not just guns. I've witnessed a smidgen of it here. Not nearly as much as some other forums. For the most part you all are some of the nicest ones I've interacted with. Okay I'm bracing for a potential barrage.
Floradawg, I agree with your words! Completed this month a year participating in this forum, I'm still a novice here ... For an old man like me, participating helps me as a therapy, keeping my tired mind always busy. However, a minimum of respect must be maintained!
There are a bunch of uses for a thread mill. Making high-precision lead screws is just one of them. Thread milling is used in industry so it cannot be that bad an idea. Getting industrial equipment to do it is a problem for hobbyists, so I for one would be much interested in how you do it. I would not worry about the nay-sayers. And I see that there are already several people who think this is a good thing besides me. Please, don't let the few who don't like it run you off!Quote:

Heck, I'm no expert. I was, for a few years, an expert photographer. Then digital photography came along and changed everything. Now I'm no longer an expert. I was an expert SATCOM operator/maintainer for the USAF for most of a dozen years, too. That's all changed, as well. And I had a long dry spell in there with guns, since all my long guns got stolen when I got shipped to Germany in the early 90's. Had two kids there, and another one shortly after returning to the States, and SWMBO disallowed guns as a hobby for the longest time. Something about feeding, housing, and clothing kids. So I'm not an expert on them anymore, either. I'm working on becoming an expert machinist. I figure it will take me about another, oh, 20 or 30 years. If I have them. I'm an owner of several metalworking and machining groups on Groups.io, most were formerly on Yahoo groups. I'm still learning, and will be at least until they nail the box shut on me. It is my personal belief that all the experts aren't as expert as they may think they are. What I did when I was learning to be an expert is try to help people who were not experts in what we were doing to become so, and to learn as much from them as I could, since their experiences were going to be different from mine. So I was pretty sure I could learn from them, too. Old military maxim is "If it's stupid, but it works, it isn't stupid." There is a reason for that.Quote:

Those who could benefit in some way from my idea lose, either on this forum or elsewhere ...
Makes more sense to me to ignore the dunderheads, but it's your choice. Just sorry you feel that way, as I'd have liked to see more about it.Quote:

WmRMeyers you and I have some things in common. I will be 67 this month and I was also in the USAF. (go Falcons) I was a RICMT (radar inputs and countermeasures technician) at Fort Lee AF Station in Virginia. We were the headquarters for the 20th NORAD Region. My final year I served at Murphy Dome AFS as a WCT (Weapons Control Tech) in Alaska. My job, in addition to other duties, was to scramble interceptors to "escort" the Soviets out of our area. I was in for 4 years from 1974 to 1978. I'm not an expert on anything, Jack of all interests, master of none. I do some metalworking, some woodworking, target shooting and a little astronomy. And whatever else I find interesting.
Picking up on the different forum threads after being away for a week:
M4A: -Jeez, man - this thread really went off the rails.
I'm truly sorry for hurting your feelings.
I just want to say that I DO appreciate your ideas and capabilities shown in several posts,
hence I merely suggested a more "how-to" approach in filming: as this is a forum for DIYers who (as I),
try to learn more by sharing, asking, suggesting and also (hopefully) constructively criticizing builds.
For my own few projects, there's has been a constant rollercoaster of progresses and setbacks, often helped by fellow HMT:ers,
by them pitching in with thoughts, suggestions and experiences bigger than mine.
For instance, achieving a good finish in my projects is a "field of improvement" I've yet to embrace,
exactly by relying on these expert HMT:ers (including you) who makes all these nicely finished builds.
I'd like to believe my own ignorance can only be fixed by actually humbly listening to critical, competent and loyal friends,
carefully considering and testing their shared input against my own believed "truths". Pretty rough cure at times, I admit.
Heck - they all waste some pretty good time in reading/ watching, thinking over and writing answers to me -
who am I to judge, brand or diminish them?
I try to focus on "principles rather than personalities", and may the best practice or argument "win",
anyone else's or mine - that doesn't matter at all to me.
I sincerely hope you can get over those feelings of persecution and victimhood you're seemingly in,
and instead will enjoy and harvest HMT at its fullest and diverse generosity.

Johan,
That was very well said. I don’t think I could express my thoughts any better.
Hi machining4all
What people have to understand we don't all have deep pockets and massive space to house every piece of machinery needed so we have to adapt ideas and equipment. So as far as I am concerned we make tools, jigs, fixtures and any other equipment to suit our needs and for our own projects and pleasure. By sharing on HMT it hopefully provokes thoughts on how to utilise ideas or simple help others with less experience. I have also stopped posting on HMT but have decided to give it another chance and I hope you do the same. My dividing head can do spiral milling but again a very expensive piece of tooling that not everyone would want to purchase.
The Home Engineer
Huh? You have been thanked 1,520 times! I can't remember anything in the past that was critical of your contributions. Why the exit?Quote:

But I will explain my own personal issues to help people understand where I am coming from.
I suffer with very bad anxiety, so posting on any forum is or can be a big issue for me. Yes I have had more positive comments than negative comments(a lot more with only a couple of negative comments in the time I have been a member of HMT). I don't mind constructive criticism or advice but sometimes it can be very negative for my wellbeing.
Example: posted a kindle splitter with adjustable wheels to be told 'you have some nice ankle knockers there' I have never had any correspondence with the person who made this comment, yes it could have been meant as a joke but I think you need to get to know someone before a comment is posted like that.
This forum has a wealth of talent at multiple levels and I can honestly say that you can gain ideas from all posts to improve, adapt or even copy to improve our own home workshops.
Don't get me wrong I have worked in some harsh environments where joking is cutting but at least this is face to face with people you get to know overtime and not from people you have never had any contact with who know nothing about you and your situation.
I am not the greatest at explaining but hope this helps with a little more understanding how people with mental health issues can see that the most innocent comment or something meant as joke can effect them. I am also sure there are some people reading this thinking just suck it up and grow a pair.
However this is a great forum and I am now in a better place and will start to post again on HMT
Again thank you to all the positive comments I have received and the 1502 thanks I have been given in the past.
I also have anxiety disorder and take medication for it which makes me feel normal. Even so I have never been that comfortable around groups of people. I have never been outgoing and extroverted. This is the only group or forum that I belong to and I really do think that overall these guys are very nice and loaded with unique and useful ideas. I am happy to have you in our group.
I have far too many hobbies, and things I'm interested in, and want to do. Also the attention span of gnat, sometimes. ;) I have done a lot of cool (and not so cool) things though. I was once helping folks document launching a 2000lb bomb down a sledtrack, through a 13' cube of steel-reinforced concrete, and then sectioning the recovered bomb in a ginormous power hacksaw. Pretty cool, but also pretty scary. That's when I learned a good maxim. "If the EOD guys are running, try to keep up!"Quote:

Some solutions are: positivity logging metrics (like Thanks votes), increasing exposure to positive events (like re-reading complimentary replies) or complete avoidance of persistently negative media sources.
Positivity reinforcement is a very worthwhile practice. It affects the way we think and therefore feel. I can chose to occupy my mind with positive or negative thoughts-the choice of how I think and feel is all mine.

I agree wholeheartedly.
Tell yourself you can do it, and talk yourself through doing it, step by step. I taught that to my special ed students, and my neurotypical students. And I've used it myself for decades. Do it out loud if you need to. I also told them that talking to yourself is not a problem, so long as you don't get in an argument with yourself and lose.Quote:

There are also some people that cannot even see that as a viable option at certain points or times in life.
Thanks everybody for sharing in this (only seemingly) OT subject!
- I've just got myself some homework in "Social Studies" to do, and some more "self-restraint to commit".
Ah - yes - a cheapo laser DIY collimator to build also.
Cheers
Johan
