When you plate irregular, long or sharp cornered objects (the end of a tube is a sharp corner at the end of a long object - thus a double whammy) it is common practice to jig the part with "thief" electrodes - like a wire ring off the end of the tube - or an extension beyond the end of the tube...

Peter, Very cool - hope it all goes well and will be looking forward to the results. (Somewhat anxiously, having steered you in that direction - it had better work.) It sounds like you have been doing your homework. IIRC when starting with a conductive paint - the initial deposition rate...

I finally bought myself a better part off blade holder vis :- This holds the blade such that you do no need to grind on any top rake (rake angle provided by the holder itself) and only need to resharpen the front clearance face from time to time. This not only extends the useful blade life and...

Can you take a photo of the motors's terminal block like this :- The terminals will (or should be) marked with U1, U2, V1, V2, W1, W2, X1, X2, Z1, Z2 or similar Also look inside the cover, there is sometimes a printed diagram sticker or moulded-in diagram of the motor circuit. As regards the...

How many terminals are there on the motor terminal block - what labels ? A photo of the motor's terminal block would help. If it was mine I would replace the complex switch with three switches driving relays - a green start button and a red stop button (Duhh..) a toggle switch for high/low range...

You photos show capacitors - so this is a single phase motor ? I presume it is a 4 pole motor which can be hooked up as a 2 pole. The double caps are start / run. 2 pole will run at 3600rpm @ 60Hz (less ±5% slip = 3420) as 4 pole 1800rpm (1710) I am guessing there will be 8 wires coming out of...

Straightening long slender shafts is a tricky business - I spent years in the shockabsorber business as well as using the rod straightening facilities for straightening (lightly) bent motorcycle fork legs bent in racing mishaps. (don't try fixing badly bent fork legs.) Using a hydraulic bench...

I think it more likely that they were British pilots flying Mustangs. Mustang MkIII's were used by the RAF. IIRC Stanford Tuck's squadron flew them for a while. Regards, Ken

Terry, Correct birds are killed by all sorts of things but the damage done by wind turbines is greatly underestimated for a whole host of reasons :- See the following infrared video of typical bat behaviour around a wind-turbine – including curiosity touch and go exploration of the object...

I'm in the robot business and everytime some politician ups the minimum wage - I go "Yee-Hah" and rub my hands together - I'm going to get to put more people out of work. (P.S. if you think I'm being cynical, robots are expensive and are at the very end of the productivity food chain - if you...

Cute graphic without sufficient "perspective" and inordinate faith in the IPCC projections at the end. A different perspective :- or longer or way longer All depends on how you cherry pick your data (timeframe, location or source). “The Mississippi between Cairo and New Orleans was twelve...

I had that problem on a previous lathe and never got to the bottom of it. Have a look at the following old thread on this exact problem - some more suggestions and tips there. Banding Finish The link will take you to page 2 of the thread and my photo is in post #35 Regards, Ken

There is no planetary emergency! At least not as far as CO2 goes – there are plenty of environmental problems that need our attention – conflating the two is just part of the smoke and mirrors. Worse its distracting our attention and funding away from much more pressing environmental issues...

Wholeheartedly agree - if someone suddenly discovered that adding lead boosted octane ratings we would almost all say "have you completely lost your mind!" but we still use it. However, I grew up in a house with lead plumbing (perhap that might explain a lot!). It is possible for refineries to...

And that's why we have "wolves" selling wind and solar unscrupulously to customers, promising them "they'll never pay for electricity again". A marketplace needs equitable rules that apply to everyone that's the role of politicians acting on behalf of the electorate. It's not the role of...

I doubt you can license it there now - it will fail the annual emissions test (It might be exempt on account of it's pre-CAT age - but I doubt it). As a visitor you might fail a spot check and be removed from the road. You can probably get an After Market (AM) CAT replacement which has so little...

It was an electrolytic process which tends to deposit way faster than current electroless types. And yes - typically only 2 thou an hour - so maybe they pushed it a lot but sooner or later that causes trouble and you end up with a pineapple. I never actually watched the process I was only...

Pete, We built up way more than 2.5mm - that was the finished thickness - we actually built it up to about 4mm to ensure we had enough material everywhere otherwise it would be scrap. The build-up was quite uneven (especially over sharp corners) but I know there are much better self-leveling...

Pete - I'll be watching closely - always wanted to design a 4-stroke. Blow by lubrication in the fuel ? Will crankcase vent be to waste or to inlet to "burn off" ? Are you going to key the pressfit crank, square, round or doweled ? Suggestion for exhausts - I worked for an electronic company...

George Orwell is often quoted with respect to this subject:- Failing scientific evidence to support their case, advocates of the dangerous manmade global warming hypothesis have turned to the “Precautionary Principle,” which argues that uncertainty—ignorance about the situation—requires...
