Hey Will ive been using 2.5mm birch 3 ply used in boat building layered with glass or carbon fiber, for constructing boomerangs, its realy easy to mold and curve and very light and mucho strong if you have a positive and a negative mold you could use three layers of that and two glass to give you about 10mm and squash them together with a load of weight then leave overnight and hey presto

As an Aussie I'd like to clear up something that hasn't actually been said yet. Yeh Boomerangs are Australian but a real 'aussie native' dosen't make his 'rang' from Birch he uses Oak! Will head to your fibreglass supplier and ask for Divinacell. Would do the job for u better than Birch. Get the one with the foam cut into squares. It's available in different size squares (I preferr 8mm) and you can brush some gelcoat in (perhaps put some tape on the mould brush in your gelcoat let that semi set pull the tape out (CAREFULLY) and and brush in a different colour and hey presto instant GT stripes. Lay in a some glass place the divinicell in glass over that let it all cure for a couple of days. Just like the speed boat builders do it ..........wait thats right I am one of yeh - better find the brudders and have drink - might see if chops and that other gb dude (#1) want to share a flaggin and chuck the boomerang .........hic!!!

....and in the lands of Mercia where Kings of old slept sullen under turf and sod strange tappings and exhortations were heard. "What were these spells?" the men of the South cried. The men of Mercia allowed themselves a quick smile for in the year to come strange beasts would roll over the land. Beasts of such speed that would make the men of the South grumble and sob into their pitiful ales. The old timers said "aye" for the sounds of Mercian hammers meant speed and with speed the spoils of victory! A bottle of cheap plonk and somebody trying to knock you off a hay bale!
Well done Will more pics!!!

no, do what us villagers do on the night of the new moon, in olde man crump's field. Bang a drum till the old owl hoots 4 times, then sacrifice a virgin to the great skull of a goat, and drink the blood that comes from them!
Then afterwards head down to either the new inn or the lion (next to the church in fact) have a jolly good piss up, then a skate down shesley!

Hey Will this is what I have in mind for my Luge cept the cardboard won't be as thick. The c/board is two layers 15mm thick with three layers of 600 weight Woven Rovings in between. I'm yet to glass over the board and top tube. Tis quite stiff. I've made three Billycarts using this type of construction and they all drive and handle real nice. Cardboard is considerably cheaper than Divinycell too. Actually I reckon Divinycell would make the structure too stiff. ..........trikes

......and verily like all decent shots of "stuff we have made'd" there is the obligatory shot of half a dog. Smashing Young William, the Mercian Kings of old will be smashing sword upon shield and yelling joyous yodels of the coming battles.
Yea Verily i say!

thank you very much!
BOS there's abt 1mm or 2mm flex in it its really stiff due to the 2 layers of fibreglass, 6 layers of wood and its shape make it very stiff indeed! The trucks are mounted on 100mmx100mmx4mm box ally that i cut to shape, was thinking about using 100x50mm box and C-section but there would be more metal (and weight) where to two surfaces met, so to save weight did it out of 100x100mm with out trucks or wheels weighed in at about 6.8kg abt 2.5kg lighter than other luge.
The ground clearance is very low and putting gumballs on does ground out so have to put risers in when riding with smaller wheels. Just ordered some more poloycarb for the fairing and something to put legs on too. Can't wait to go out and ride it!! will polish it up for cadwell!!
Will

Love that birch / fibrglass deck. What I don't love is (and it's only my preference) is the sharp corners / angles of the alloy. Sharp corners create stress risers..........trikes
