Hi Peter,
If you’re looking for wheels alone, Northern Hydraulics has 'em. All kinds -
And for, as you say, a ‘trundle’ or something similar; small-ish inflatable wheelbarrow wheels might be the way to go. http://www.northerntool.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=6970&productId=11949&R=11949 is one, they have lots more. - see http://www.northerntool.com/webapp/wcs/stores/servlet/CatDsp?storeId=6970&N=124+7380
Typically you can snag them online for under $20 each, use a zinc chromated bolt of the appropriate size for an axle ( or, again, score something appropriate out of the junkyard ) and bend a frame for it out of conduit tubing. If you or if you know somebody who welds a bit, voila.
Though one nice thing about the jogger’s baby strollers - they are meant to fold for stowage - adding a longer beak to 'em to tow behind a bike wouldn’t add that much. And as many of them use what is basicly a pair of wheels off a kid’s bike, you could maybe find tires and tubes of greater width for better sand floatation.
Another possibility- might work better for what you’re thinking of- is to redo one of those Garden-Way-type carts, the two wheeled deals with a couple of spoked wheels on it - another yard sale score to look for.
Basicly, add a board rack to it and it’d carry boards, suits and what have ya.
Easier still, and I stumbled across this while looking for a picture of one of those garden carts-
http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=44599 - they are on sale for $30 just now - about what two wheels alone would cost.
Have a look at the assembly instructions: http://www.harborfreight.com/manuals/44000-44999/44599.PDF . As you can see, swapping things around ( put the long, U shaped bar on the straight section) and adding a little pipe insulation foam and a couple bungees or nylon straps and you’d have it.
If you wanted to add a couple U-shaped sections of conduit to get the boards up more above the sand and so forth, not difficult to do, you could even lash on a couple pieces of plastic pipe if you wanted to. Just emailed a link for this to The Prosecutor - I may have to do up a couple of these for him and myself as bike trailers. Wouldn’t fold, but pretty compact by itself.
hope that’s of use
doc…
