Thread: Boiler making

Add to that, you will want some BIG gas torches and PLENTY of fire bricks (and a deep pocket for silver solder). An assistant can be helpful.

Thread: joining metals

Stainless steel, use soft solder (lead based if you have some). Clean the joint and use Phosphoric acid as the flux (Jenolite rust killer) - other products may work.

This is getting silly

and just to be really silly, how about using some Cerobend - quite brittle but melts at just under 100 deg C, so would have to be kept away from the hot end of the bar - perhaps not !

I wonder if 'hard' brass would shear easily enough, otherwise graphite carbon Eg thick pencil leads. or how about some of these - wouldn't break the bank

I seem to remember having that stuff at School, experiment to show how steel expands and contracts on cooling. A bar was heated between a couple of fixed points, a test piece of cast iron was slipped into an eye of the bar at one end and as the bar contracted on cooling, it would snap the test piece.

T N Guy, I set my pendulum clocks up with an app on my phone that listens to the 'tick tock' and indicates out of balance, period etc. It just needs a quiet room. search Cucko clock Calibration or similar.

What sort of flue temperatures would you expect a fan to work at (choice of fan case and bearing materials) ?

Thread: Chatter

Again, may be an illusion, but is the tool bit horizontal, or is it at a negative angle.

Or is the boring bar too big for the diameter it is cutting ?

"We'd just advise the public to make sure that their electric appliances are properly certified and meet current British standards," she said.

That sounds a bit daft - it means that we have to change everything for the latest BS. Do I have to upgrade my 1932 Austin 7 to the latest emission regs ? Ahem, I think not.

Thread: Customs payment is it a scam

I have posted a small gift from France to Australia, gift had no value, but FR post has a minimum value of 1€34 which has to be paid on receipt in OZ (Apparently).

Thread: Why are BA taps so blooming expensive??
21/09/2020 06:54:46

Try our "Cherished suppliers" - TracyTools. You will be pleasantly surprised. Also, I rarely use a second tap, just taper and plug. Why HSS ? Carbon Steel for the most part will give you good cutting and life etc at £1.50 a tap. However, I do prefer HSS dies.

Thread: WHY THE TANG?
20/09/2020 11:36:48

On Googling "Why do large drills have tangs" I came across a reference which stated that on larger machines, if the drill taper slipped, and quill feed continued, damage could be done to the machine. Having a tang prevented the taper from slipping. As we all know?? Its the taper that does the work, but if the taper were compromised by trapped swarm, burrs etc, then the taper comes into play.

I could live with that explanation.

years ago, we placed a sealed bid on a council house. We were the highest bidder, but the successful bidder was a builder with "cash" available.

Thread: REMOVING STEEL BOILER TUBES
18/09/2020 21:43:39

Would it be a good idea to de-scale the inside of the boiler first ?

Thread: Soldering stainless steel
17/09/2020 11:22:56

As AW says, Phosphoric acid - its what we used on the aircraft (away from the plane itself) down at Weybridge. JENOLITE is a "rust killing" product you can buy off the shelf that contains Phosphoric acid. I am sure there are more perfect products, but I usually have some of it on the shelf - Other products are available.

I notice that the video doesn't show him putti on his hands or taking it off - A bit suspicious to me !!

Thread: WHY THE TANG?
15/09/2020 18:25:08

Does the tang help in the manufacture of the male end of a drill, reamer etc. Have you ever seen a centre with a trang on it ?

15/09/2020 11:21:17

Sounds to me like the morse tapers aren't true - the tapers should lock themselves without the tang.
