Two types of engineer, those that know and do and those that solve equations but can't do. OK it's a scale, but for me those define the end points.
most of the people I was at university with fell in to the latter with only a few of us sliding along the scale to the former. i believe most now work in banking.
nice doohicky Dr.
I don't know whether it's a function of the area I work in or if I've just been lucky, but most of the people I work with are somewhere in the middle of that scale and reasonably comfortable working anywhere along it. I'm probably more comfortable with the equations than a lot of the engineers around here, but there are a few who make me feel
really stupid! Most, if not all, are quite comfortable building practical things.
Most of the people I went to university with went into banking (I think 40% of the class went into engineering

).

I am in awe of everything you do Dr. Al! Metal, wood, 3D printing. Then you also show your programming skills by writing something in C++ (!).
To be honest, that's at the easier end of the scale for me. I'm an electronics engineer by training and a lot of electronics these days involves programming microcontrollers in C (although I still do a fair amount of analogue stuff too). Hence my day job involves programming and it's something that comes quite easily to me.
Metalwork is something I can do thanks to 11 years practice at home. Wood machining isn't
that far removed from metalwork in many ways. Hand tool woodwork is something I need a
lot more practice before I can claim to be competent at it.
The thing that impresses me most in the stuff that other people do on here is the artistic design side of it. I can design functional stuff reasonably easily as that's the way my mind works, but making stuff look pretty is a skill I don't have!

Although I enjoy reading the builds on your website, It's a shame you don't have a YT channel because it would be very interesting!
It's never tempted me I'm afraid. Firstly, I have limited time in the workshop as it is and I suspect that filming what I do would double the time everything would take. Secondly, I spend enough time in front of a computer as it is and editing videos would increase that dramatically. Thirdly, I'm not exactly overflowing with charisma, so I doubt a youtube channel would be very successful! Finally, I generally prefer reading (& looking at pictures) than watching youtube videos, so it would be a bit hypocritical!

Thanks for the explanation. I had to look up four start thread…..never knew such a thing existed. Every day is a school day.
Multi-start threads are probably most common on milk bottles and things like that: they allow the cap to be screwed on very quickly but don't need much thickness of material (depth of thread). I put one on the fidget spinner thing just because I'd never cut one before and I thought it would be an interesting challenge.

I got that wrong Al, I assumed that the threaded part had just been drilled and tapped to accept the other end which had been threaded to suit.
That's (sort of) how I made my first, smaller one (on the mini-lathe; visible on my monitor stand in the last photo on
this post). One part had a male thread section and the other was drilled and tapped. The join was still in the middle of the threaded portion though, so both parts were threaded. For the second one I was lazy and used the threaded rod to join them - that made it easier to be absolutely sure the joining faces were flat.
