armour

does anyone know in 2mm mild steel will hold up against the beetle spinner

It would really depend on the angle, but generally not that great I don't think. Thicker plastic armour or titanium would hold up much better.

unfortunately i haven't got a tig welder so ti is out of the question as the shape i want will need to be welded i could bolt some plastic round the lower half or get some high carbon welding rods and leave a bead of weld round the lower half

Its all a bit hard to say what will work as armour yet, you may well be fine with 2mm steel if the angle is right. What exactly are you making?

I believe you can stick/arc weld titanium if that helps.

I am going to be gambling on 3D printed armour so it cant do much worse than that now can it. I would say its fine, but bring a hammer and something to beat it against.

3d printed beetle? Nice! Care to reveal any details? Sorry, bit off topic.

i was going to do a slightly more complicated beetle version of scruffy

also i have looked for stick rods for titanium and i can only find the rods for tig

3d printing could be good and at least it would be easy to make spares

Would love to see a beetlweight Scruffy :)
That has fairly slanted sides, and doesn't have that many flat panels for spinners to catch. Hmmm. Have you considered bending 1 price of material instead of welding?

ive looked into others methods but welding is the easiest with what i have avalable

Sorry to go kinda off topic here, but harry mentioned using titanium, so what kind of thickness would people use for a beetle spinner/horizontal thwackbot/melty for structure and stuff

There have not been enough recent Beetle events for any kind of patterns to emerge but I would say 1mm of Grade 5 Ti should be able to take most of what a beetle spinner can dish out.

The softer grades (1-4) would need more but you could bend those back where as you cant with anything Grade 5 and up.

Thanks
So 1mm grade 5 and 1.5 to 2mm grade 1 to 4
Ok
Im thinking of re doing shred, but this time it may be tough enough to last more that 0.376 seconds in the arena. It may even be able to damage something tougher than a cereal box :)





The 0.376 seconds thing is completely made up btw

Btw, why cant you bend grade 5 ti

It's hard but more brittle (I think) so will snap rather than bending.

Grades 1-4 are pure titanium in a variety of structures and oxidisation levels.

Grade 5 is the first Alloy and contains 6% aluminium, 4% vanadium and a maxiumum of 0.25% iron. This makes it incredibly stiff (Bending resistance), hard (Scratch Resistance) and tough (How much energy it can absorb before deforming).

I don't think it is technically more brittle than G1-4, but when you bend it you damage the structure in such a way that links on the outside of the bend break and when you bend it back you snap it as you only have half the thickness of the sheet which is structurally intact.

Ok, thanks for that :)
Interesting to know that g5 ti is an alloy

Grade 5 will bend, but not bend back without cracking.
