Help required in designing traverser please

How about bog standard drawer runners? You can 550mm ones from Screwfix :

You could try filing cabinet runners, they come out further and are more robust than regular draw runners. Mind you they might be missed at work!

Cheers Pete,

I thought of using those as a guide however ...

The family's push bikes will be stored underneath it ... hence the height above the floor and also the problems associated with having enough clearance for folding legs. So as you correctly guessed my big problem is providing support. I could have a "mandraulic" prop which just wedged underneath it when fully open but I really wouldn't want to rely on that sort of technology.

...

Nice ...

As it happens, besides my more usual job at work I'm in charge of the stores ;-)

Ah I can see a stores compatible design coming on here!

Phil: Then why not use the elastic straps from one of the bikes as an additional means of support - but going upwards to the garage roof / wall?

Actually you will find that the 'office' type twinrail runners advocated by another correspondant have very little sag, and are available for example loads of 40-50kg per pair (designed to support HEAVY VTRs at FULL exptension in broadcast equipment racks) - ask if anyone is throwing out an old DVR18 ! 8-) !

No straps, besides I'm not sure that I'd be to keen on building a fiddle yard on what would amount to a trampoline ... although it would give a new dimension to the term "backjumper" :-) Intriguing idea all the same though.

If I can get hold of some I may well try a set out didn't appreciate that they would be so strong. Meanwhile (if anyone's interested) I'm going to try to build a mock up over the weekend using tongue and groove floorboards ...

Thanks for the tip.

Another thought.

Make the baseboard above the traverser a smaller width than it. Then run the tracks on the upper board towards the back, and the tracks on the traverser towards the front. That way you won't need to pull it out the whole two foot to access all the tracks.

It's a thought, if I took 6" "of the top" so to speak chances are I coud get away with a travel of only 18" or perhaps even less.
