Team Coolspeedbot: first feather weight robot

[daveimi]

Oh wow how did u melt the nuts in and where did you get them? I've not been brave enough to try yet lol. Is that a cheeky bit of gta going on there :P

I followed this guide by Ellis but without a pillar drill: https://www.youtube.com/watch?v=AcII...cEveUFO_-4neUo

I used a old drill motor shaft fitted into a drill chuck and pressed the heated nut in.

I got my nuts here: http://www.ebay.co.uk/itm/1811604491...%3AMEBIDX%3AIT

They are 3/8 unf hex nuts.

yes I'm watching a lets play as I work.

Popped over to my local Halfords and got a bike tyre for tread to add to the wheels.

Considering you made them without a pillar drill, how much wobble do the wheels have? I was tempted to do this myself, but wasn't sure how well it'd turn out.

There really isn't any, the drill shaft I use to hold the nut when I heat it and press it in has a section I can use to align against the bore to keep it straight as it cools.

I've done the same with Luna-tic, plenty of wobble but I've allowed plenty of wheel clearance and to be fair you don't notice when it's bolting around. Ellis's videos have helped me tremendous with building. Hats off to the lad.

Something like this Alex?

Yep, that's it exactly. Those are both great!

Top one looks like Firestorm from back in the day!

Yeah it does.

Well it was a good job I bought a spare 'sheet' of HPDE for Wolf-E as I made a mess of half of the first one .

What do people recommend as the method to cutting 20mm thick HPDE?

Jigsaw. You need a woodcutting blade, set it fairly slow and take your time. Make sure you always cut on the waste side of the line. Also if you want to be a bit more careful, you can use a regular handsaw or a coping saw for rounded edges, although obviously it takes longer. Might want to get yourself a hand plane to straighten up those edges afterwards too.

I see, going to need to replace the Jigsaw then as my current one has developed a safety issue.

I got a green one from Argos (not sure of the brand) which worked fine for me. It was like £20 I think.

I just ordered a new one now I just need to solve my other issue, drilling a hole that doesn't go at an angle.

[R9000]

I need a drill press pretty bad. I just need somewhere to put one. :P
