There was a documentary on YouTube of someone working at BAE down in Barrow. Poor sod was welding two halves of a submarine together. Looked like he was progressing about 2 inches a day and working his way around the diameter :(
If you feel up to it, you could test the chip. If you look at the datasheet that was previously posted, you'll see that the inputs are up one side and the outputs are up the other. When 3.3 or 5V gets fed into the input, then the corresponding output gets connected to ground, completing the...
I think with square box section, you have a lot of strength in the horizontal direction that you don't need so much as strength in the vertical direction. If you plated the outer openings of the I-beams, that would create two large rectangular sockets, then you could maybe use a rectangular...
We did this on an agricultural bale trailer to have a 4 long by 8 foot wide removable extension. In our experience, you'll bend the box sections on the extension long before you need to worry about the welds on the receiver sockets giving way. I think ours was done with 80×80x6 box if I remember...
Some further information for yourself and others who are interested. It's a custom made trailer for a niche application with a mostly flat deck, about 4m long and 2m wide, 700kg gross weight. Due to the requirement for unusual cutouts in the trailer floor, I have a long thin area in each corner...
Thanks for the search terms. Stainless is very much in the "nice to have" category and I hadn't really considered just how drastically that might narrow down the search pool. This sort of thing is almost certainly too finely toleranced to hot dip galv.
I'll have a look at the Zoro link.
Now that is an interesting idea. I like the price, I like the length and I like the fact that it seems to be a course enough fit to galvanise. It's a far larger diameter than I would have liked but there might just be room.
Thanks for the links. I'll contact them for pricing but I think it'll be a premium product meant for CNC applications. I was hoping to find something cheaper because I don't need such levels of precision for what I'm trying to do.
I'm looking for some threaded rods to make bespoke trailer levelling jacks. Something like what's in a G-clamp or those cheap little jacks that come next to the spare wheel in a car. I'd be looking for lengths of about 600mm and a diameter somewhere in the range 16-25mm. I'd prefer stainless...
I ran 1mm only for years for a range of fabrication on light box sections of 2.5mm wall and plate up to 15mm. I've been doing less and less plate recently so I moved to 0.8mm and I'm delighted with the results on lighter stuff. A lighter wire generally makes things more controllable on thin...
You put your black probe in the COM port as always. You put the red probe in the one marked 10Adc, assuming you want to measure a fairly large current up to 10A. Rotate the dial to point at 10A at around the 4 o-clock position. You see up at the top right where it says A then a bar with dots...
As above, the technical term is Finite Element Analysis. Full blown professional grade FEA software is very expensive and impossible to justify for occasional jobs.
However, a popular package for hobbyists and small companies is Autodesk Fusion 360. It's quite a nice CAD package which will do...
@sako243 It's a subject that causes a lot of debate but it really boils down to what you're trying to achieve. I work in Power Electronics research so most of my inputs are analogue measurements that I then digitize. Any pushbuttons I have tend to be doing a set/reset job so if it bounces it...
Either use veroboard/strip board or get the job done professionally in China for pennies. You'd frankly be mad in this day and age to invest money on kit to make your own boards which will turn out a fraction of the quality at far greater cost.
I wouldn't bother debouncing your switches in...
I should point out that we only use 16A sockets. We've got three running off a single breaker. It's mostly to save changing plugs over all the time, we rarely run three things at once. I think the incoming fuse is 100A per phase but it's a 63A breaker feeding the whole workshop anyway.
We've used "strings" and the larger "plugs" for many years on the farm for ATV wheels up to tractor tyres. I have been told by several people that the strings are not road legal.
I keep meaning to buy a pack of the "plug patches" where you pull them through the hole from the inside and they...
Crikey, I think I ought to look for another laser cutting firm then. I had to totally redesign a part not so long ago because they came back to me and said it was impossible to cut a hole or slot narrower than the thickness of the material, unless I wanted to pay a fortune to have it CNC milled...
