What's with the rollers on the wheels ?

What's with the rollers on the wheels ?

They are called Mecanum wheels. It makes the car omnidirectional

Can't quite grasp it.

I am going to design a body and see if I can get it 3D printed at work.

It is strange, I find them amazing. They look like they shouldn't work but they do!

 

[nickk]

All purlins and rafters fitted,now made a start on roof sheets.

 

[My Old Landy]

Fully finished with its own bespoke remote.

Are we talking Davros?

I am when I travel around in my wheelchair the dog certainly doesn't like the car but is ok with the chair!

If we were talking Weird Science, I'd definitely be paying extra close attention to this build.

My son made a horizontal carry sheath for the junk shop rescued mini sheath knife.

That sounds rather grand. I was thinking some duct tape just to cover it.

30 odd years ago I routed the edges on a cheapy home made construction ply 2.4 m x 1200 . bench to take 30 x30 mm x 3 mm or so equal angle iron , mitered at the corners , counter sunk the screw heads flush then tigged the corners when it was screwed down in place .

It's quite a stretch to cut a four-foot wide sheet. I think positive clamping helps. My first time set up was pretty terrible and I had the track sticking out on my side, so it's easy to knock the track with your body when concentrating on the cut and leaning over. My excuse was that I was trying to get it done before the heavens opened. The sun got out in the end, as it happened, but it was grey skies when I started. I've gone and ordered some clamps as per zx9. They are far too expensive for what they are.

I think it also depends on the thickness of material being cut, thick stuff takes more effort to push through and the track is more likely to move compared to thinner stuff,

Instead of reaching across a wide board have you tried cutting it from top to bottom when the cut is vertical .
You can set it so you simply run along an F clamped straight board that fits under the saw motor .

Some good points there, Dapph. Those light plastic trestles do a job, they take weight well but aren't the most stable or anchored of things. The contact area is pretty minimal too. Next time I may prop a sheet against the garage wall, raised up off the floor a little and try like you suggest.


With regard to the table-top edges, some gaffa tape is working OK for now. I will band the edges with something solid soon. Probably a bit of wooden trim, flush with the top, so stuff can be slid on and off without hitting a lip. I think a fancy architrave would be fun to try, but a plain flat side might be more sensible.

Richie, I have a pair of steel folding trestles that I use with 3 ten foot scaff boards with my tracksaw. I spread the boards to make a gap where the blade will cut through. The clamps can also be accommodated in the gap, although I rarely use them. I can cut 8' sheets along the length like this on my own easily.

 

[Richiew]

Once my table is in its final resting place I'll be able to use that to cut off. Should be problem solved at that point, I hope.

I finally got around to making some holes in a bit aluminium plate to mount this lot -

And then realised I also need a 5VDC supply, and checking that I realised that there is a flaw in my plan which will need some differential receivers to solve

More rollers last night. Think I'm getting the hang of it now

 

[redlig]

At the other end of the scale from Munkul and after many minutes of design work I managed to stick together 4 bits of stainless 12mm bar. Anyone guess what kitchen use it has? Size 200x150mm.
