Coincidentally, I really needed a square too.
I thought I’d copy yours but didn’t have any metal so I used the same as you have in the middle of it.
What do you think ?
A dummy speaker. Well four of them actually. I have some dead audio gear I need to get round to fixing, but I don't want to risk blowing up a pair of nice old Wharfedales testing it.
Not much welding involved, but a fair amount of drilling and tapping to attach four 50W resistors to a big heatsink.
Case was 3D printed at work.
It also means I can do a burn-in test at full power without annoying the neighbours.
I needed to run a bead along a section of engine bay surround that I'm making for my project car - the original had quite a few rust holes in it. First of all I made the repair section, got it curved in both directions spot on, then tried to add the bead (it's like an angled step rather than a bead). First problem was that all the step dies are far too big - this is around 12mm x 7mm. I had a go with the cutting pair, but it wasn't much good. Ended up using the hand joggler, and it was all over the shop.
Next I tried the bead roller on a new piece of steel, put the step into the steel and then tried to fold it up. This was OK, but I really struggled to get the bead straight. A couple more test goes showed that I just can't do that by hand. I've been intending to make some sort of back stop for the roller for ages, and kept over-thinking it. As I've recently salvaged some thicker steel from the scrap pile, I ended up with this:
Currently it has to be clamped into place, but I might try to do something about that. It's not ideal for the job I made it for because it means using a much-oversized strip of steel, but there isn't a way to put it any closer to the rollers, and the extra width makes the steel easier to handle. First test piece through was spot on, folded up in the right place and is now tacked onto the car. You can probably see that the welds on the back stop haven't penetrated fully, which I suspect might just be my welder not being up to it. If I get trouble with it I'll have a go at moving the welder so it's not on a 65' extension cable, or drill and tap a couple of holes for screws.
