  1. Cool, in a roundabout way that's how I did it. I used a couple cardboard shims each side of the rotor and wound in the adjustment screws on the caliper in until it gripped the rotor, then I tacked it in place.
  2. Is that good or bad? (Just googled answer...cheers) Just did a quick test to check that caliper geometry is right, Success!
  3. Haha...it's like you were there, I went to take it apart and thought "dam it!". But if I loosen everything I can (only just) squeeze the wheel out. For now I'll just leave it as a hole. Can always mill it out later if need be.
  4. Logic tells me that this should work, but part of brain is not convinced? Logically, the geometry of the caliper is pivoting around the wheel centre as everything is on a fixed radius. So it shouldn't ever bind...well I think that's right? It's a bit of a mind fuck, as the wheel moves twice what the leaf spring does. But I'm sure this caliper is neural??? Ahhhh...hope I'm right??? Other than being crippled by uncertainty, I'm pretty happy with the overall concept. A disc braked leaf spring front end on a velobike. Everything will get a tidy up later, but time to move on to the next challenge.
  5. Got a bit done on the pivots this afternoon. Needs more work, but I have some ideas to improve it like turning up some more plain bearings etc First step was to fill up the original fork holes with the "hot metal glue gun", then Linisher to bring back to flat again. Then I started the pivots Plain bearings and split pins will be added later, plus tidy it up.
  6. Ummm kind of. It's complete, but no spark yet. I've brought a couple coils and will hook those to a battery to bypass the magneto. Pete ran it like this, so I should be able to replicate his method. Engine will be next move, and the work back from there to finish.
  7. Bit of a lazy day, didn't do a lot. But did achieve a few small steps all leading in the right direction.
  8. Got up early, excited like a little kid on Christmas. Last night I was faced with the dilemma of where I was going to mount the compact bender. But in the early hours of the morning I had my epiphany! If I mount it with (4x) 16mm dynabolts, into the concrete floor it's going nowhere. And if positioned just out from a door pillar, I can get the full 270° of articulation when both doors are up. The arm can come off and hang on the machine, completely tucked out of the way...and it's in what I would call dead space in my shed i.e. a space that has no other use...win, win...win! It handled the 16mm cold rolled solid rod with relative ease, producing a perfect bend on my first attempt! Fuck yeah...love this tool!!!
  9. I made this a couple years ago using a mates workshop, tools and help. He said to me if I ever decide to get rid of it, be sure to send it his way. Last year that time came...so I gave it to him to keep. It seemed only fair considering without his help I never would've been able to build it i first place. I told him about the drome racing and sent him a YouTube link...now he's keen as! So too are two more mates, so if possible we have a gang of 4 ready to take on the dome!
  10. Brought two cool new tools this week to use. 1) step drill set Which did an amazing job cutting a perfect hole to fit this volt meter in. I feel stupid for not previously owning one, as I now appreciate just how good they are. The second tool is a compact bender. I'm feverishly googling and YouTube-ing up a storm on how to set-up and use one, as I've never used one before. Looks easy, so once I get it bolted down I'll put it to use tomorrow.
  11. Yeah, that flat part of the tank that sits on the frame by the front of the seat. That would disappear if painted to match the frame.
  12. Hi, what's the rules on indicators and stop lights? There are those clever led strips that do just about everything (lights, split turn signals left/right and rear brake light). I'd love to bend one around the inner lip of my rear fender, or perhaps under the seat? Is this a reality...or will a certification engineer just laugh at me and tell me to pis off? Your thoughts/experiences please? Thanks
  13. Like, like, like! Awesome project, and so beautifully engineered.
  14. Girder frontend underway Still a fair bit left to do, but it will have to wait until next weekend.
  15. Forget world peace, solving the famines in Africa, and whatever bullshit woman say about how difficult child birth is...this my dear friends has to be the most difficult problem the world has faced! No...not that No that was easy, just slap it in the mill Bingo! Yup, an innocent looking little pull start. But it's not innocent, Satan had a lead role designing this system in the 1940's when he realised humans were getting tired of killing each other in WW2... so he cursed the world with this pull start mechanism, and the suffering continues to this day! 8 hours spent on this over two days trying to figure out how the fuck this pull start works!!!! 8 Fucking hours!!!! But it now works, and I'm exhausted...my brain hurts, my fingers are bleeding and I'm covered in carcinogenic grease from 1943 when this was last assembled. 8 hours!!!!
