I got one of their stick welders a few years ago and I'm not impressed with it. It has what amounts to a thick or thin setting, and usually I want in-between. Probably be better with a thicker cable (read - lower resistance). It is possible to weld with it but a very frustrating experience for...

Yes, then. I wondered how cables had different veloicities. I was going to build a little TDR device (never got round to it) and came across it then.

Drill!

Is this where "cable velocity" comes from?

Oh, there are dill speed / feed calculators online if you look.

You can get these micro drills from AliExpress much cheaper and in a wide range of sizes. My collection now runs from 0.3mm to a whopping 3.17mm. You need to run them at upwards of 10,000 RPM. The tiny ones should in theory be run around 100k RPM. I've built a PCB drill that runs at 30k RPM...

If you can get them big enough, why not use barrel nuts? The only real disadvantage is the hole you'd have in one side of the leg, but you can hide that.

Some very knowledgeable people here. Some of them are even helpful!

These could have saved me a world of pain so many, many times! Must get...

You need to drill into the brick (stone, breeze lock, whatever) and use plugs and screws long enough. Whatever product you use, you will never get a sound fix in just plaster. Plasterboard you might have more luck with proper fixings but 9 times out of 10 you want to fix to it where there's an...

Ooh ooh I used to have one similar. Wish I still had it...

Yep, broke exactly as you predicted. But i found the diamond coated burrs go right down to 0.8 mm, and I think those will be much better for me (cutting very tiny slots in grp board - circuit board fabrication to be exact). Probably won't be as neat at the corn mill ones, but that won't matter.

Oh yes, found them on Aliexpress. Thank you. I think the diamond grit abrasive ones might be mores suitable for me though - so thanks for that. The 30 degree engraving bit - I actually have a couple of those, never used! But I need the slot to be parallel sided so that wouldn't really work...

What do you call this type of cutter? It's the largest one (3mm) out of a set I got off eBay some years ago. Really annoyed because I just broke my 0.8mm one. Then I broke the 1mm one. Apparently they jam quite easily! Is there a more suitable micro cutter to cut a slot in a board, connecting...

I have an Evolution Fury table saw! It belongs I believe to the class of "contractors saws". Infer from that what you will. The biggest downside is that the little cover that fits over the blade (sorry I don't know the name for it) doesn't sit flush. So for cutting wide stuff it's perfectly...

My imagination is running round in circles....

They sure are pretty - but you should make sure your using a "food safe" epoxy and colouring.

I once had an old Wolf drill, and had the same kind of problem removing the chuck, for the same reason! Turned out they used a tapered fitting (most likely JT - Jacobs Taper). So you just need to wedge it from behind (ideally in opposite directions, simultaneously) and whack the wedge. I can't...

Motors often respond well to some TLC. Take it apart, clean it, ensure the bearings turn freely. If a brushed motor it's most likely to be as simple as needing new brushes, no dismantling needed. Branded ones are expensive but you can get generic ones cheaper: just measure the old ones (or, more...

Hand held twist drill holders are useful on those delicate occasions when you would otherwise be using the drill with your fingers. There's been a few occasions I haven't quite bought one!
