Wilfy, I've put this on your build log rather than hijack the other one. If your looking for a local steel supplier try doing a google search. I have just done a google search for "steel stockholders wigan" and up popped about 4 quite big companies. Probably more if I looked harder but there's a start for you. Guessing any one of them will offer you a better price if you actually go & see them rather than phone up.
yeah thats on my list of things to do, i did email one company to find no reply, but i'll work out how much steel i need over the next few days and then i know how much i need to order, the other problem is getting someone to deliver it
wilfy, I'd offer to get the steel for you but by the time you've either courriered it to you or come and collected it (5 hr round trip) you could probably buy it for the same price locally. Plus I can buy the odd thing through work but if they see my buying lots of steel then questions will be asked if you can wait until wobbly orders then I can tack it on, but still got the problem of getting it to you....Neil...
You will get a better price if you actually go there rather than email, that's always been my experience so always try to speak to people face to face if I can.
If you can't get it in your own car do you not know someone with an estate or something like that? Just rough cut it on site if the supplier won't cut it for you.
I have a people carrier but all the seats bar the one I need have been removed so really it's small van size. Seats just clip in so if I do have to ferry anyone about I just stick them back in.
Try them all lol, take a list of sizes you need & ask them nicely if they will cut it to length for you, they may charge you a cutting fee but it may be worth it. Even if they won't cut it all to length you may get a couple of bits cut so it fits in the motor.
hmm been doing some thinking tonight dangerous i know..
looking at the size of the moving parts it now feels when i look at it that everything i've designed i should have a bigger work space.. what i mean is the foot print of the machine is 792 x 700 and yet this produces a cutting area of 385x385 and i'm starting to wonder should i bump up the length of the rails and screws to gain some cutting area... the only down side in this is extra cost which i might be able to come to terms with.
i suppose the biggest decider is at what point do i need to move away from 16mm screws and rails as this will be the limits of the machine for me
i've also added in the green bits for stability... with the above thoughts i'm also thinking of changing the 50 x 25 that supports the y rails to something wide enough so that the whole yellow section can slot in to the blue as at the moment it feels like wasted space that could be better used to shorten the ballscrew and the steel
infact just a quick look at getting the yellow section to tuck in to the blue i could gain 100mm workable width for the same size screw in just 100mm longer rails so i'm going to consider a slight redesign to make this happen
Edit: i've done it so it's the above with 100mm shorter rails or this one below with 100mm longer rails screw is the same length
