If this RC speed controller explodes I think i'd be able to replace it with one made for electric bikes on there. |

Ugly flash photo of current progress. Cutting that aluminum bar was a chore, and i've got to do it yet once more~ It took a terrible amount of time to then turn the bar down. Alot of it was spent trying to make a tool that could break the aluminium chips since they were getting kind of dangerous (one whipped my face!), which I finally managed. Didn't take any photos of it yet though. I'm still undecided on how to attach the wheel to the shaft. It's a light press fit as it is. I'm thinking either loctite (the kind you can heat up to release it if needs be), set screws through the thicker part (with the holes covered with the tyre), or a pin through the thinner part. I'm liking the idea of pins the most since it won't require buying anything, and i've learned from experience that grub screws are hard to find (and i'm sick to death of ordering stuff online). Unfortunately i'm kind of getting to the point where the project doesn't seem so exciting any more. I think my favourite part of any project is the 'solving problems and learning new stuff' part, and the rest sort of feels like going through the motions. That's not to say I wont finish it, it's just i'm thinking about other stuff most of the time (right now I can't stop thinking about turret tailstocks, and how i'd build one without a mill! It's part of the banjo plan). |

It will be pretty exciting to sit in that seat and strapping on that war helmet, shoving off and switching on, though! :poke: |

I could probably have it together for a test ride in a couple of days if I get my act together. Still got to build the whole control side of things before its complete though. As a side note, I was at the boot sale on Sunday and spotted 4 different big tubs full of laptop batteries. If there's as many next Sunday, I might buy them all. I'd only really given up on the idea of assembling a battery from old laptop cells after finding out they cost a fortune on eBay, but if I can get them cheap enough it might still be preferable to spending more on RC batteries. Plus lithium polymer is kind of frightening! |

No shortage of aluminium chips! Here's the tool. It only really works on facing cuts, but it's ideal for hogging out the bulk of the material. It's a fairly deep groove. It might be old hat to some people, but i've been trying to make a tool that can break aluminium chips for ages with no success till now, and it certainly makes life easier. I also found I could cut the aluminium bar with one of those little TCT blades I got at Aldi a while back, the saw it came with has little power so it tends to stall way before it would risk kicking back, so I could keep rotating the bar in the vise and cutting as deep as I could till it stalled, then rotating the bar and starting again. It's not ideal, and maybe a little bit dangerous, but preferable to spending several hours hacksawing through the thing. A powered hacksaw is still on my list of things to do at some point though. |
