I figured out how to build a seat extender that allows an adjustable angle by using an old folding bike stem. So I cut the centre off an old set of handlebars and welded them onto the seat post. Sadly my welder was out of gas and the welds sucked, so I need to get some more gas before I can try again...

Almost a year since I last updated this.  :-[
I need to get on with making it usable - my daughter is pestering me to ride it work before she goes back to school (though the chances of her being able to ride it are almost nil (it's set up for me at 6ft and she's 4ft - pulling the bottom bracket back far enough for her to reach would mean the cranks bashing the crossbeam)).

I did look at my little scratch start TIG, but the dials on the front are damaged/missing - I should probably just get rid (and, if funds allow, get something more modern).

Don't underestimate the ability of a sufficiently determined child to ride a recumbent that doesn't even slightly fit :)
There's a photo somewhere of EldestCub successfully riding my Streetmachine with his shoulders leaning on the bum-end of the seat and his back arched over the steerer...
Careful, Kim. Your sarcasm's showing...

Many, many moons ago Redshift and I were standing on Morecambe Prom eyeing up various offerings at CycleFest. I suggested she had a go on a Trice and got a vaguely negative response which included 'It's probably set up for someone much taller!' and so on.

Five minutes or so later a chiddler of about 7 trundled past on one. Backside wasn't even touching the seat . . .

Well that's the more blunt way of putting it but as usual he's dead right.

I have grainy video of ?SmallestCub photobombing a BBC Midlands Today interview about all the cycle infrastructure they were about to build[1] by doing just that.


[1] Spoiler:  They didn't.

The last of those glorious events was in 2004!  :o

If it ain't broke, fix it 'til it is...

I molished a random backrest for this and rode it on the rollers today.
The old backrest was shaped ply with special captive nuts and sensible bolts, but I couldn't find it in the garage! New one was a part of a shelf, held in place with wood screws. Worked better as it had more height and so supported my upper back better! Now all I need to do is cut some random steel, bend it to a suitable headrest position and work out how to stiffen it sufficiently to stay there. :)

Side note - I saw on a BHPC picture the other day a steering damper on some old trike. Anyone know what that was nicked from? It might make it easier to ride this thing (outdoors) without every tiny bump bouncing the steering around the place.

I resolved the neck rest with more wood, and I rode it about 5 times on the rollers. I've gone back to the upright for now as I can't get enough resistance on the rollers (I was in the biggest gear I have at 90rpm doing around 200W), and also because I don't have my 'bent legs and I don't want to lose fitness getting them (this is, after all, just an experiment - I'm not racing the thing).

I can answer my own question - there are loads of steering dampers for go carts and also for motorbikes on eBay.  At some point I'll actually try riding it outside again, and maybe at that point I'll decide it needs one, but I'm not going to bother until then...
