Team Oh, It Broke Build Logs

Post by Tufty »

As mentioned in the "how big is your beetle" thread a few months ago, I'm dipping a toe in the beetle-infested waters soon. For now I'm going to try to build a simple invertible wedge out of a couple of RC cars and as much metal as I can get into the weight limit. I'm fully aware I'm not going to win any competitions with them, but it would be nice to have something to sacrifice while I probe you all with inane questions while your machines' guts are exposed!

Shattered a few drill bits, but I've got side armour build now. Need to get the ramps built so I can fit it all together, but a little research into the type of armour I need has to be done first.

Shattered drilling what material? I find nice and slow with a bit of oil usually helps in metal. I've snapped drill bits in HDPE but that usually comes with any of the following: the result of a jaunty angle, bad holding of the drill or bending whilst drilling.

It was purely my own impatience, and they were 1-2mm drill bits so not especially strong to start with. Only drilling aluminium, presumably with a bit too much force.

First major mistake, I ordered some brackets to bolt the various panels together. They arrived today. Where I was expecting reinforced L-brackets of about 3cm on each side, they're nearer 3 inches each side. One bracket weighs over 300 grams! Looks like I'll be building some shelves in the near future. Meanwhile a fresh batch of more appropriately sized brackets are on their way, and I've cut out the aluminium bodywork. Waiting on titanium now to reinforce the wedge.

Ended up changing plans somewhat: a pair of Nikko Nanotrax cars turned into wedges with titanium armour all around and plastic on top for weight reasons. Just need to add the safety link to the electrics and I'll have a clusterbot. Sadly with COVID I'm not sure competitions are letting more than one person per team compete at the moment, so I'm also working on converting a Tumblebee in a similar sort of way. Not absolutely sure about the armour specs there yet though.
