Is this for lighting suppression or is it one side of a direct to earth radiator?

Whats the application? 50’ of 11mm wide 1.4mm thick flat strap will just turn into more metal to vaporise in most lightning contact events. I have a significant amount of experience building lightning suppression in an RF environment, if you can reveal the application I may be able provide...

I did my apprenticeship at a traffic signal repair work shop, we used to get foreign order requests all the time for drivers for the old signals that got sold off at the departments salvage yard. If you are just making them sequence like real traffic lights, forget the $5 challenge, let’s see...

The 1.8 stainless is going to be expensive overkill. It’s just an easy to clean veneer, 1mm is resistant enough to dents and way cheaper. I would also consider using two layers of 16 or 18mm form ply over the MDF. The MDF will take on water from the atmosphere and swell over time. Formply is...

I use a Pressmaster at work and a Crescent CCT10 at home, although I’m finding I’m going away from insulated lugs in favour of Deutsch connectors for a lot of stuff.

The books are cool, the paperwork from the space and missile division just makes it sub zero.

That length of bar got turned into M10 (stud size) and M8 for setscrew clamps, I’ve also roughed out another length but haven’t dimensioned it yet. I’ve not seen those rotational types before, that second bar might get turned into some of those. Thanks for the info and link, much appreciated.

So while you guys were building thread cutting heads from scratch I turned a piece of rusty shaft into some T nuts for my new to me Rong Fu dovetail (something of a step up from from its round column predecessor). Some days it’s the simple things.. like not losing index when you raise or lower...

There’s a lot of names on that list I recognise or know personally. Did your Dad ever go to Hay at all?

I want to see the compressor and drier set up that was attached to that dehydrator manifold, that is seriously bad boy!

Nice collection of tooling you have there. My larger stuff is Edwards, made in England. I have some rusted fingers on my folder also, my plan was to bead blast them, wet/dry them with light oil to remove the blast marks and then cover them in gun blue. Not sure why, but on things like that...

They are available new out of Melbourne. From memory last lot was $4 (AU) ea

So if I’m understanding this correctly, you have a PC accessible to inmates connected to your CCTV/PA system? If that is the case that seems like a bad idea to me.

Stream the radio via the PC you have connected now is the simplest answer. What you have is CCTV overlaid with a broadcast PA system. I suggest you hit them up for training on it if they expect you to maintain it.

Tight fitting joints, some practice on the offcuts and 023 wire will see you right. 16G is no more difficult to weld than 1/8 once you have the machine dialed in and your groove on.

If you have the drills why not get a chunk of ally or hardwood and cut it to your desired shape and make one

I just put a hex to square adapter in my ratchet screwdriver, way better than anything I’ve seen in a socket set to do the same job.

I have several empty index boxes if you want one at postage cost only

I have about 50 in a box if you want to pay postage on the qty you require
