Making your own tandem mountain bike.

May 15, 2015

Latest creation over the cold, wet winter. A tandem mountain bike! Built mainly using spares in the basement. Interested in how I built it? No, well worse luck….

The frame is a cheap steel tandem that you can find in many a location second hand, with different branding, but the benefit of this specific frame is it is reasonably lightweight, and can take 203 discs (A must on a tandem rear brake, as you need to drag brake for long descents). It will have parts on it. They will always be really really bad.

Important Parts

The wheels are a set of Force cartridge bearing hubs. Cheap but tough enough to take a beating. They have been built on a set of Spank downhill rims with DT Swiss spokes. These are really important to get right as a buckled wheel on a tandem is no joke. Any large downhill rim will be perfect.

The bike will come with a cheap tandem chainset. It will be made from horrible steel and feel all flexy so feel free to fling it on eBay, or into the fiery depths of the sun. Whichever is more convenient. Instead I went with a 1×10 chainset with the timing chain on the spider ring. Benefits, you can use a normal chainset! You will need to flip the eccentric BB holder in the front as it probably will be reversed for the original timing chain. If you don’t do this the bottom bracket will sloooooowly loosen off!

203 discs front and rear. Tandems benefit from matching rotor sizes, as unlike normal MTBs the centre of gravity doesn’t move as much. It makes for a better ride and more predictable braking. SLX brakes with an extended rear hose provides enough stopping power.

LED Light Tube Bicycle Light

January 17, 2012

Light Tube Bike Light

Quick creation for my bike. Light tube from Poundland, and a torch mount for rifle barrels from eBay.

I am really impressed by what a great bike light it makes. Cost around £3.50, and much brighter than most LED rear lights.

I keep a small Knog light on my bike however, just in case. It was from Poundland after all!

DIY Library Catalogue Computer

June 17, 2011
Or how to create a Library Catalogue Computer for free(ish), with whatever you have in the store cupboard, using Linux and the tame e-resources Librarian (That’s me).
The Library where I work has so far been succumbing to my evil machinations, specifically on the theme ‘Put Linux on everything that doesn’t work properly’. I have no desire to constantly fiddle with unreliable IT resources, not when I have far more productive things to do.
Our newish Linux Web server and Content Management System has been, if not a roaring success, at least a loud hurrah. And it hasn’t caused me a single significant problem since I hit the ‘online’ switch.  And it’s cheap, which is jolly good news.

My salad bring all the vegetarians to my yard, and they’re like, it’s significantly crunchier than ours.

My herb and salad garden seems to be going great. Without any pesticides and only organic fertiliser. It is strange to think only a few months ago this was nothing but an overgrown pile of broken glass and numerous large unidentifiable metal objects.

The wooden stakes? They are a frame for a DIY cloche I made to speed up the growth of the seedlings with sheets of recycled plastic painting sheets. It worked a treat!
