Having look now.
I'm confused then, what should I be using for structural walls? If I used 1mm steel I wouldn't be able to weld it, so what would be the best method to attach it all together?
Or should I use a fairly thick aluminium alloy? Euuurgh. I don't know and there's nowhere else but here to ask. ;_;
I feel like a bug. xD
Welding thinner metals is much easier with a mig or tig welder but with good welding skills and thin welding rods you can theoretically weld thin metal with an arc welder.
I remember seing someone clamping a piece of material (copper or aluminium should do the trick) behind the weld to be a heatsink and help prevent blow through. I would suggest you practice on some scrap pieces first though.
If you don't want to weld then bolts and angle plates are probably the next best bet.
Hijacking this thread for a quick question.
I'm in the midst of building my first real FW which is going to be powered by 2 standard drill motors and 1 additional for the weapon.
I'm aiming for it to be compact and was wondering exactly how far from the motors I need to put my 2,4ghz Spectrum RX?
I've seen very tight builds and was curious if there are any significant interference from motors when using 2,4ghz equipment?
I will twist the cables to the battery and the motors but havn't planned on using capacitors on the motors unless i experience interference.
I'm also thinking of shielding the RX with a folded piece of aluminm but not sure if it would help.
The spectrum 2.4ghz eliminates 99.9% of interfearence so not to worry .....
I was wondering why general purpose tufnol wasn't used in featherweight machines, what reasons are there behind that?
Thanks.
Sorry for the bump.
Finished the workshop today, got my vice in, drill press and wall grinder, not too shabby!
I can't seem to find any hardox sellers on ebay or commercially, where ought I be looking, or should I just use mild steel?
I'm going to go right out there and say I don't understand motors, I can't find a decent resource to teach me about them either.
All I think I know is that the higher the current on a motor the quicker it runs down a battery. Other than that I know nothing.
Learning process I suppose, so if any of you could give me a quick lesson on working out torque, the benefits for gearboxes on motors and voltage's effect on batteries I'd be in debt to you, if not that if any of you know some resources I could use that would be brilliant. I have looked at the riobotz tutorial extensively but some of it's extremely advanced for me. Even so it has been ridiculously helpful, thanks for posting that!
Thanks again! Sorry for all the trouble.
for hardox you can get it from jl steel, mtl steel, direct from ssab or from a private seller ie someone on the forum. i've bought some hardox off gary recently, not sure if he still has any though.
Wow! You're very quick, thanks a bunch to both of you.
I've been doing some cad work using google sketchup, and my design so far looks like this:

It looks rather sparse, simply because I have two problems, assuming I use graupner speed 900s I'm not sure what batteries would be the most efficient to use, plus that and the set up, parallel or series?
My other idea was to attach a belt to the front and back wheels so that if a motor died out the remaining motor would still run both wheels. This came from the idea of having only two motors to save cost and weight but I'm not sure if that would really benefit my rammer design. Any advice would be brilliant.
