/\ wot he said,
Aluminium staging/decking is cheap enough used and will last forever.
You can also get fibreglass coated boards cored with foam or honeycomb at reasonable prices (not a huge amount more than marine ply), won't ever rot and are really light but they dont stand up to hard abuse...
If it's your first build it may be easier/cheaper to find an existing horsebox as spares/repairs and just repair or rebuild it
Then you would only have to replace existing parts rather than worry about designing new ones.
Ramp springs can be a nightmare to get weighted correctly and it can take...
The truck in the photos has a fair bit overhanging the rear wheels.
If I was doing it I would go for the ramp on the side to keep the weight forward.
If it's only for ponies maybe even partition the back off and tie them as far forward as possible. Put a foam cord panel across the back with a...
Anneal it, flap disc the basic shape then refine with a course stone.
Then harden and go over the edge with the stone again.
The blood groove and the tang step (if it has one?) could be done with the edge of a grinding disc, marker pen first and maybe make a small guide run with a dremel wheel...
The current situation is:
I have cut this bent stub out..
And taken some rough measurements
The bearing surfaces are both damaged so I will find out what sizes they should be and get a set of proper dimensions.
I'll get some bar and some bearings and drop the lot off to you with some cash...
One of the sparks will know the actual ratings but I think it's something like 1/3 less so if it's 95mm2 it should be fine!
Although it does make nice light leads I don't think it stands up to repetitive flexing like copper does so might be more prone to breaking up internally eventually.
It might be simpler just to get one of the £10 digital tachos and stick the pickup on the output pulley then it would read correctly if you change speed via the belt.
Some inverters let you set a ratio or run a 2nd display which might be possible if you dont need the full speed range and won't...
What's the existing wire coming out of the machine for then?
I don't have a clue but my guess would be that that cable feeds back to the copper bar going to the euro socket so to change the polarity you just plug it into the - and put the work clamp in the other hole?
Edit: ignore me! I thought...
As above, even if the 400nm figure is genuine it's a bit low for a 1/2" tool.
I have a 1/4" that does 200nm.
I think there would be times you would find you still need to crack off with the bar and in those cases you would be better off using the smaller/lighter 3/8 you have to spin thr nuts off...
Another option is something that takes a roll of paper.
I have got an HP wide format, although it is very wide it's not very high or very deep so some of them take up less space than something with an A3 paper tray.
You might be a bit limited on what media is available on a roll (although you...
It might just be a newer model then?
I had the dialog version and I did have a copy of the pc interface software.
Not sure if I still have it as I think it went with the welder but it would be interesting to see if the connection on yours is live and talking if you could find a copy?
I would like to think of you were managing a project like that then you would have fixed the prices with the suppliers before hand?
Although if it's public money then probably not!
On the upside, scrap should also be going up and I haven't done a weigh-in for a while..
