I bought a Wowstick electric screwdriver. It sits on the back of my desk and lends the whole room a air of class. Occasionally it's wafer thin, white LED switches on to show it is diligently keeping it's battery in peak condition. The decks are patently cleared for action, I know that one day I will find a use for it and it will be glorious

Sounds like you are to receive Scotland's UN Climate Change Compensation Grant. Since they told Trump he was a horrible person the CCC money has been adjusted to a more realistic level

Maybe take 6mm off either side to stop it bending?

Expanding mandrels? I am suddenly 60 quid lighter

I did Sinclair's stereo amplifiers c1973? Worked for approx. 2 seconds then were no more. With hindsight I thought I got the PSU wrong, but maybe I was an innocent bystander

I couldn't afford the posh Sinclair calculator but I got the cheap one in kit form. Later I was given the posh one by my college tutor which was fun.

You are assuming the rest of the world to be incompetent, and it usually is, but someone with a use for such a monster as this should be fairly well equipped for a bit of soldering.

As our American chums would say, "Heads up!". Today i bought a Casio fx-451M calculator NIB from America on that auction site. If you ever had one you will know why this is amazing. Solar powered but there is an internal battery to retain mode selections, you have to know where to make the incision if it goes flat. He has 4 more

They lined them up to tow them away and we schoolboys pinched the can of detonators the way school kids do. You knew which ones were to be towed because someone had oxy-acetylene cut through the piston rods.

Presumably you mean field carriages? I have two, original 6 pounder sea service carriages, c1800 in my garage

Steam is relatively low pressure so I suppose the O ring might actually retain it's shape rather than becoming a squidged up smear of rubber driven in to the low pressure corner. Could you actually use one as a sliding seal? That seems a bit unlikely but maybe there is a trick to it?

Is that blue and grey thing a harmonic drive? I had to buy one of them just so I could take it apart and see how it works. A bit like Sylar if you remember him. Darned things are about the same age as me but I'd never heard of them.

Fascinating gizmo, looks like an epicyclic box but does 50:1 in one stage and the output goes in the opposite direction to the input

If you want to do a Sylar you are welcome to borrow it.

I designed the perfect stepper mount. You bolt the motor shaft to the end of the shaft you want to turn. You run a bar out sideways from the motor body. The bar comes up against a stop. You add a spring to pull the bar against the stop and there you have it. It is mechanically perfect, stress free, cheap as chips, no possibility of backlash, any misalignment is self cancelling. Unfortunately it would look ghastly and the motor is going to wobble all over the place. Can't bring myself to do it

There is also the layer of Aluminium oxide on the surface of your billet. This cuts a groove in the side of the tool which can be reflected as a raised band on the finishing cuts. If the groove is near the tool tip, probably because you are cutting at a budzillion rpm and it will burn out if you go deep, that could easily start a catastrophic crut build up. However the worst culprit has to be pure aluminium which always prefers to flow when you want it to cut

If you can also do shelves, I suspect my wife would rather be married to you

Have you tried, "Alexa, where's my stuff?"

Okay, you stand on the roof rack and I'll toss them up to you

I used to have either Mondeo or Passat estates until one day the Passat driver's side door rusted out inside, the way they do, just before MOT time. I was stuck without a car. Eventually decided to buy one on my way home from lunch. Got a Civic 1600 SE on an 02 plate as a stop gap and now I cannot bear to part with it. It goes wrong occasionally but the parts are so cheap I don't care. Only problem is I can only get small cannon in the back, six pounders are out of the question

I can dream about bending the rules but it's all pie in the sky. The goblins in my head insist I keep to the straight and narrow if I want to sleep at night

So when someone in Brazil asks me to value it at US$10 and declare it as sporting goods on the CN22 that is okay because it is his responsibility? I like it.
