Brass Thumbscrews?
Anyone got a link for reasonably priced brass thumbscrews, nuts etc for tools? I'm happy working with sheet and round stock, but knurling is running down a metalworking rabbithole I'm trying to avoid, and I'm finding it very hard to find reasonably priced ones anywhere... Grateful for any and all pointers. M4/M6/M8 would be good.

Aliexpress.
I’ve got some M4’s on their way; they ended up being about a dollar each shipped.Nothing succeeds like a budgie without a beak.

I make my own but can't even buy the materials for the cost off the completed items on ebay and aliexpress.
Of course being able to make my own I can do custom work like this one for these old dividers, thread was 5/32" 32TPI.
This was made from a brass tap handle.

These were 3/16"

And this chipbreaker screw with the the unusual 9/32" thread

Unless you buy it through Amazon, a minimum price for anything from the US is going to be about $51USD. $50 of that will be the USPS minimum charge! Amazon Prime shipping bypasses the USPS. But, there are very limited offerings that qualify for the free shipping unless the price is (ba-dom-tish) $50 or more. ¯\_(ツ)_/¯
I have bought quite a few things (mostly small stuff) from the Chinese retailers since this nightmare started. They have been 100% reliable in my experience, just not as fast as before.

I know Mark. I just have this increasing frustration with anything that contributes to the Chinese economy. I look at Tibet, the Uighers, the South China Sea, intellectual property theft, etc etc etc, and find myself thinking of Stalin’s line about ‘selling them the rope with which we will hang them’... I avoid when I can. Personal stuff, no beef with anyone else who has to make a cost-benefit decision.

Bob, that’s lovely work. You swine; I’m intrigued! How much does a basic knurling kit cost?

Well for a start you need a metal work lathe.
Knurling tools usually fit in a lathe tool post or tool post holder and (cheap push type Chinese) start at about $25. These are fine for brass.
A better type of tool to use on steel uses a scissor type action and these (from India) start at about $75

All of those are real things. None of them good.
I can compartmentalise the policies and actions of the CCP from the Chinese people; who are just like people wherever you go in the world. In much the same way as I do about the USA whose government -- let's face it -- has hardly been a paragon of virtue through history. I'm not specifically referring to events between the 20th of January 2017 to present. Though these have been ugly to watch, in many ways they pale next to the gauche interventions in other countries' affairs in earlier modern US history (Iran, Vietnam, Nicaragua, Cuba, Colombia to name just a few).
I had an interesting conversation with a colleague of mine who is a relatively recent immigrant from China. My colleague did not understand our relationship with the USA. To that person (and a lot of other Chinese people, no doubt), it did not make sense.
I explained our shared history with the USA back to and including the Second World War; and how we were preparing to cede everything north of the Queensland border in the event of invasion. Then I explained the personal actions that many Queenslanders were privately enacting in preparation of that event occurring.
My family live in what is now known as the Sunshine Coast. My Great-grandparents are buried there. We've been there a while.
My Mother, who at the time was a little girl, remembers the extended family going to Warwick in about 1942 or 43. She is understandably a little hazy on the details but this would have been a monumental logistical exercise under wartime rationing. Being a little girl, that would have flown right over my Mother's head of course.
It was only later in life that the penny dropped for my Mother that this was an evacuation exercise.
My Chinese colleague went real quiet after recounting my family's story; then quietly said: I get it now.
I get that trade is not the same thing as a personal interaction with a fellow human. But; positive interactions (of all kinds) we have with other people in the world cannot do harm.
Stalin -- ultimately -- was wrong. He was a shrewd man, but hardly a great student of history. Regimes come, and go.
There will be a change to the Chinese political governance mechanisms at some point in the future; and that will occur organically, and be precipitated by the Chinese people themselves. It might be better, it could also be worse; but there is bound to be a Gorbachev or Yeltsin in the CCP somewhere. I'm certain there is a Putin in there too, however.
Whether anyone alive today will live to see it happening is an entirely other matter. But, nobody really foresaw the events in Eastern Europe of 1989 occurring either.

I did a lot of searching about five or six years ago and then tracked down five or six suppliers in UK. Unfortunately I have lost the sources!
Would not even search in USA because they will only have Chinese stuff and you may as well go to source. Plus rip off postage.
I remember someone on this Forum making some very nice thumb screws by braising a brass bolt inside a brass garden hose fitting. Wish I could find that post.
Personally, I love thumbscrews, preferably oversize, and absolutely hate wing nuts.

I think that was probably Derek Cohen; HERE is a link to the appropriate section of his website. IanW has also mentioned this trick in his plane building manual but I don’t recall if he ever posted it in one of his build threads as he has a metal lathe and generally makes his own.
