As the thread title implies, what home made or custom bike related projects are you thinking about, in the process or stuck on?

    I've got two but I'll keep them in separate posts for easier tracking.

    My first is now more than three years old maybe even older, way back when I bought my first magicshine light I quickly found out that the battery was/is gash I also had one very scary burning battery incident which prompted me to buy a dozen sets of single 18650 cell holders with the idea of building my own removable cell packs, which should mean I can finally reuse all those laptop batteries I have knocking around.

    Here in lies the first problem, for love nor money could I find a glue that will bond these plastic shells securely together.

    Taping or strapping was part of the design I had in mind, so the projects stalled.

    Any recommendations to get this rolling again?

    The next project is in two parts, born in part out of boredom whilst stuck doing turbo sessions and in part due to my insatiable desire for stats.

    I want to connect my phone(s) or mini tablet to my Garmin out front mount using the quarter turn method. I use Android not apple phones so most off the shelf options are out and the quadlock looks far to bulky and expensive for what it is.

    So far my two options appear to be, cheap cases, 3M VHB tape and a 3D printed Garmin quarter lock blank from raceware for £10 or a £3-4 SRAM adapter filled down and stuck in a similar way.

    The question is which adhesive VHB tape would be strong enough? or is there an alternative method bearing in mind it'll only be used on a static bike but will be removed after every session.

    Quite a selection to choose from http://www.3mdirect.co.uk/3m-vhb-tapes? ... rder=price

    Ever heard of Sugru?

    Google it.

    Sugru with magnets kit will be a start.

    I have yes I ruled it out as to bulky and a fairly expensive solution. Ultimately my aim for the battery pack is <£10 all in and the mount something similar.

    The ultimate bond is out there somewhere.

    I'd never heard of sugru. Was worth reading this thread just to find out it existed!

    For gluing the battery boxes together, would airfix glue do the job?
    Another option might be to bolt/glue/pop rivet the holders to sheet of plastic or thin metal.

    As for my contribution to home made stuff, I had some Evans vouchers for Christmas and quite fancied a backpack cover. I went to the local (40 miles away...) store to have a look to see if they would fit but they didn't have any in the store.

    I had a load of old hi vis jackets at home from previous jobs so stitched some Velcro to it and to my backpacks and hey presto instant hi vis backpack cover.
    I got some red electro luminescent wire and an inverter off ebay and hey presto instant hi vis 70s disco backpack cover :).

    The things I've learned from this are:
    • Borrow someone's sewing machine for stitching the Velcro. The backing is really tough and I ended up with several pierced fingertips from pushing the needle through and several broken needles.
    • Rechargeable batteries are useless in the step up voltage inverters you get off ebay.
    • Putting your arms through the arm holes of the hi vis while it's on your backpack can lead to embarrassing moments of getting stuck in your backpack in the office, particularly if you have a dodgy shoulder after coming off on some ice the week before.
    • Being hi vis makes absolutely no difference to the number of cars trying to left hook you. This evening I even had a van driver slow down alongside me and give me abuse about it.

    This glue is chuffing amazing. I know you're a bloke, but read the instructions. It gets stronger if you set it in the oven, but then it'll start to run a bit more in the time it's setting, so have a test run first.
    Sometimes parts break. Sometimes you crash. Sometimes it’s your fault.

  • the BOFF, I have magicshine lights as well, and brought the big water bottle battery you can get for them, never had an issue with the batteries and now there is a new y splitter for the new and old lights to join together its great. Only issue i had is with the rear magicshines, seems after a month of my constant using the twisting motion to set the lights kept rubbing the wire to bare metal until they frayed so much they stopped working.

    I have a homemade double bottle battery pack, its what i replaced the original unit with i also took the head apart and re soldered the wires in, clean out the whole unit and secured the fixing points. One of the battery ends isnt as tight as i should be and used to disconnect so i applied some good old fashioned bluetack.

    I paid money for one like this off eBay (£3 or so).

    quoting to remind myself to reply to this properly tomorrow. I'm doing quite a large battery build out of 18650 cells, not really cycle related but it started by getting some 18650s for my lights.
  • anthdcianthdci Posts: 543
    This is my project, and while it's not bike related, I got my first 18650 cells for my ultrafire bike torches. I then started to see what else they would power, so moved onto battery packs that can charge my phone or tablet. Then I started using them when I was away in my caravan last year. We do agility shows with the dogs which is setting up in the middle of a field for a long weekend, anything requiring power needs to come from batteries. I don't want to use a noisy generator and solar panels are expensive.

    Then I got to thinking about using quite a lot of these 18650 cells since they store quite a large amount of charge for their size. For comparison, a lead acid leisure battery rated at 100amps weighs about 30kg for £60-100, I have made four 24 amp packs that weigh a total of 7kg and cost me about £1 (I work in IT so can salvage laptop batteries for free).

    PhotoJan2345135PM_zps4b64f56c.jpg

    My aim is to make a suitcase with 8 of these 24amp packs, an inverter and some 12v car plugs. So should power pretty much anything I can throw at it. I don't do roughing it camping.
    PhotoJan2343623PM_zps85ffe9f8.jpg

    I still have quite a few thing's to work out, how to mount the plugs, running some temperature sensors for safety. I have some relatively low discharge protection PCBs but if my other half wants to use her hair dryer these will trip so need to sort something out regarding that.

    Its been done before but here's my best project to date.

    Frustrated by the price premium of Brompton specific luggage, I modified an Ortlieb Front Roller City to fit a Brompton S-Type Carrier

    Top fixings lowered about 3 1/2 inches to fit carrier. Original fixing holes covered with Heavy Duty Duck Tape (looks like a re-enforcing strip on the original material). Top of internal backing plate secured in place inside pannier with Duck tape (as fixings are no longer at top of plate). Drill out rivets of side bars on carrier. Cut down side bars to match width of bag (about 2 inches or so, but making sure there is still enough straight section for R&K fixings to hook onto) and re-rivet. 1hr, max.

    Hey presto a 12.5l fully waterproof Ortlieb Brompton bag plus carrier at a far lower price than any other Brompton S-Type front luggage option which looks like it was shop bought (and you even get an extra Front Roller to sell on or use for commuting).

    Still too much money for my primary use though...........................carrying fish and chips from the chippy!

    Sorry, terrible photo's but all I have available

    Nice mod but wouldnt such a large bag on the front of a small or any bike for that matter make handling horrible?

    especially if the contents moved around

    Actually its well known that adding front luggage to a Brompton improves the handling! Those small front wheels can be twitchy and extra weight creates inertia against the twisting forces
    Also as mine is a S-Type this is smaller than bags designed for the other handlebar types, which are higher, in order that it does not snag on the brake levers
