Thread: 1/2" x22tpi tap?

I work on Bugatti's and they use M7, M9, M11, M15 etc!

Thread: Steel identification

Most scrap yards use these now, especially on stainless steel and ali-bronze.

Hi,

I had to order a length of 16mm diameter EN24T from a supplier in Birmingham because it was out of stock at my usual suppliers. When I turned up the chap started rummaging around on a rack saying this might be it, he promptly went off to the office and came back with a small handheld gun which he pointed at said steel. A small LCD display clearly labeled it as EN24t and listed its chemical composition. I went away very impressed.

Sadly these things are £8000 plus. Given the way electronics is going, perhaps every home workshop will have one one day

Regards.

David.

What size do you need? Someone might have a bit kicking around. I'd be surprised if EN8 woudln't do, there's not that much difference

There is a lot of difference. I have seen steering arms made from en8 snap like carrots! I always use en16t or 24t and so far none have ever broke.

I always mark offcuts with number stamps so I don't use the wrong steel for the wrong job.

You would need to do a lot of cutting to get your money back!

Thread: Aluminium Firebox

Molten aluminium and water is highly explosive!

Thread: What thinner for Enamel paint.

Owatrol oil.

Thread: Boiler material

It depends what temperature you will running at. There must be a formula for calculating heat versus strength of steel. The higher the temperature the weaker the steel becomes. The comes a point where you get a sudden catastrophic failure, that's why steel beams in buildings have to be incased in plasterboard.

Thread: If starting again, what would you buy with a budget of 5k?
10/03/2019 10:30:34

Not a lot! Might get some of the big stuff, lathe and mill not much else. A couple of years ago I did a rough calculation of the value of my tools and stopped when I got to £50K. Some of my Stahlwille spanners are over £30 each! A Hoffman dividing head second hand will set you back £500+

Thread: How do you make a lifting eye

It would be too hard to make a die and hammer them out as they are quite small.

Thread: EN1a vs EN3 steel
06/03/2019 10:11:02

EN3 is a weldable mild steel. EN1A contains lead to give better finish but is crap to weld.

This looks like a bargain for someone. Lathe

Thread: 3/16 bsw screws

Meccano screws.

Thread: Slitting saw speeds
22/02/2019 21:21:27

Start off slow and increase speed until it cuts without building up any heat.

Thread: Clarkson Tool & Cutter Grinder Fixture

Does anyone have drawings to make a universal head for a Clarkson tool & cutter grinder?

Thread: Hello, Alexander master toolmaker
21/02/2019 19:59:17

Mine is model number 1489. & PGIE 20degree PA

21/02/2019 09:53:51

I have one too. I was told that the designer was a jew who fled Germany with the design during the war. I have a vertical and the over arm for horizontal milling and it can shift a lot of material in this mode. I also have a slotting head from a another copy of the Deckel. I am looking for a tilting table and a dividing head. I did manage to buy a complete set of fed gears from a chap in Rugely who made them in batches.

Thread: Another newbie question!

You could use the steady to support the end of the bar.

Thread: How many threads please?

The ideal is 1 1/2 times diameter
