When I worked on stainless industrial centrifuges, we scrubbed the threads with molybdenum bisulphate paste then coated them with a mix of molybisulphate and grease. You know it's galling when it starts to tighten so you try undoing it to start again and it tightens up even more. Horrible.
I have a job making a handrail up the steps on the side of a small barn in the cotswolds. I'm using 20mm square for the uprights with a rail on top. The rail will have a simple scroll on the bottom end. Fairly simple. One thing I'm not sure of is how far to sink the uprights into the stone...
I made water cooled generators with cheapish tegs and they never failed, even on a blazing stove, because the cooling pulls the heat through fast enough that they Don't overheat. Higher temperature ones typically also need a much higher temperature difference to generate voltage , which is...
Tegs have an incredibly long lifespan. 300,000 hours is pretty much standard, even on cheap ones. Failures are usually due to getting the cables too hot then they melt the connecting solder. If something stopped the fan turning then the heat sink wouldn't dissipate the heat fast enough and that...
The best thing about these things is that you can see all the way from the kitchen when it's time to put some more logs on the stove, because the fan slows down. Otherwise pretty useless. I tested one by lighting a lighter in front of it and the flame didn't even move.
I built a proper...
Also, there were two British motorcycle newspapers, both of whom relied heavily on advertising revenue, from BSA, Norton, etc so they wouldn't ever dare say that a new model was a reworked pile of steaming dingo kidneys now would they?
Could be wrong but I believe it started during ww2 as a cheaper way of doing it, dying and smoke flavouring. Same with kippers. Undyed are far better but my favourite are bloaters, which are hot smoked whole and are superb.
