    ' No Weld ' Plans

    Yes I suspect you're right there. I know from my machines that the weight really starts to increase after the frame is made and you start adding the 'workings'. Each bit you bolt on seems to make a big difference to lifting it up on the bench. Building strong is easy but building strong and...

    ' No Weld ' Plans

    Well we had nearly an inch of snow a few weeks ago which lasted almost two hours before melting. And sometimes in Summer we can have two wasps flying around in the house on the same day. You think you've got it hard- you just visit Norfolk, UK! Can't make up my mind re a bolted 'bent. Two...

    Why shouldn't I???

    I came acrioss this page this morning. http://ihpva.org/Projects/tstrike/kingpin.htm Several ideas for what you are thinking of and alternatives. This is the main page from the site with loads more interesting info. http://ihpva.org/Projects/tstrike/home.htm John

    Why shouldn't I???

    I think it's the centre point steering which would be spoiled if you did this rather than ackerman. I saw a similar idea somwhere on the 'net a while ago. It had headtubes welded to front fork inner legs but it looked really horrible and amateurish and was probably awful to steer and very flimsy...

    lifepo4 battery pack

    8 hours? Hells teeth I'm puffing like an old train after 8 minutes. My Dad died the other year just as I was retiring and getting my leg sorted. It would have been great to cycle to him a few times a week rather than use the car. About 2 miles each way along back roads would have helped with my...

    Nothing to lose really.

    Sounds like me on a good day Danny! John

    lifepo4 battery pack

    Hi Paul. I used to visit Danny's area often since I had a boat moored in the Dauntless yard for a while. I confess I never did much other than visit the yard but recognised odd bits of Danny's cycle journey he put up on a vid. That particular route looked quite pleasant as I recall. I'm about 7...

    lifepo4 battery pack

    Oh sorry to hear that. I must have got my chronology confused. I thought you and Paul had done a foreign trip since your accident and that you were mended but guess I was wrong. Well at least your spirit and sense of humour aren't damaged and you're still planning and building. Keep up the good...

    lifepo4 battery pack

    Hi Danny. These cells have made up a pack which, on paper, is about 18AH. Doubt the seller figures (I doubt all seller figures for everything these days) and I'll keep the charge down to 80%-90% anyway but will be plenty for me as I'll not be doing any long rides in the immediate future. This is...

    lifepo4 battery pack

    Just to report I have my pack finished and working. I made a hard case for them from a lightweight plastic (1/4" thick solid sheet originally a sign/placard). Glued together then sheathed in epoxy soaked nylon for strength. I hadn't quite realised how large and heavy a pack 33off 32700 cells...

    Delta trike design - constraints and solutions ?

    I've been a bit confused with the maths and the close-up shots of sections of this design for a while now. I'm still not up to the maths but now I can see the layout clearly in the last few pics I really like the look of your machine Paul. Hope you get to the metal bashing stage so I can see it...

    A good advert for NOT using wheel chair wheels ?

    Looks like the two tiddly wheels may be set high as the front one seems to be off the ground several times and he's riding on a pretty flat surface. He has two wheel steering but the little wheels look really flimsily hung to me. Like I say the front one as he heads towards the camera is...

    A good advert for NOT using wheel chair wheels ?

    Like the 'outside the box' thinking and the body shape is nice to my eyes but just so much about this machine is wrong! It's easy to criticise but the whole thing just seems too weak and completely unfinished. I slowed the video to 25% where he is heading towards the camera and all the wheels...

    Second delta doubts

    Yes you got it for sure. Either one makes sense now. I'm sure there are a few odd bits including a motor and couple of small wheels somewhere in a box and some sort of toothed belt drive. Small and low powered by looks of it so would fit with the invalid scooter idea nicely. No use but good to...

    Second delta doubts

    It was worth a try but Joan complained she had trouble balancing the iron on the sticky-up bit. Women- just never happy eh! Oh hang on though. Maybe the sticky-up bit is actually a sticky-down bit and I had the whole thing upside down!! John

    Second delta doubts

    Untangled the other oddity from a shed to take pics. I really looks to be a chassis for an upright trike but can't see where the pedals would go and be able to spin? It's ally but still built heavy. Has half bearing shell type inserts at the rear. Would be interested if anyone can see what it...

    Second delta doubts

    Track is a bit narrow and it's built like a tank- way heavy. The steering was actually one of the best things about it. Nice heim joints with ally tube track rods and full ackerman geometry. Was dismantling today and found a sticker which said RWS (iIrc) Cycles of Peterborough. I can't imagine...

    Second delta doubts

    Paul I am following your threads and am in awe! I don't have either your patience or your design/planning skills. I'm way too keen to 'get it done' and tend to use what I have available whether strictly suitable for the job or not. Any results which are actually moderately successful are a...

    Second delta doubts

    Just thought I'd put some final results up on here to show that I have actually done something in the last few weeks. This Mk2 is pretty close to what I wanted to achieve but still hasn't quite hit the spot. It is certainly useable and will give me a nice trike to be using while Mk3 is in...

    lifepo4 battery pack

    Yes there's not a great choice out there. Opinions seem to be that cheaper ones are prone to failing but expensive ones are crazy prices and the programmable ones are way over my head. My cells are much the same with no more than about .01v between any of them. I'm actually going to build a 11s...
