Hi all. Well, gearing up for some landsailing again over the summer and have a project. How do I go about building a class 3 axle?

From my reading I have discovered people using Sitka cedar, Red Wood Cedar, Spruce, Ash, Tassie Oak, Oregon...

As someone who doesn't delve into timber work, can I ask if anyone has any recommendations? Especially from an Aussie point of view regarding the sourcing of correct timbers.

tassie oak is a s good as you'll get in Oz. if you want a softer axle consider making the top lamination out of maranti. another good wood here is RAMIN. but need to select a springier one.
when picking your planks put 2 blocks on the ground at the right distance apart then lay the plank on and jump on the middle. I like about 3 bounces 5 is too springy,1.5 is to stiff. a cracking noise means put it back on the rack. i do this instore before purchasing the wood Nothing with knots, and grain needs to perpendicular to the flat of the plank

Ok, I can tell everyone wants to answer a stupid question. Would laminating several layers of timber (ie: 2 or 3) together (epoxy) or a single piece plank be better? My father has some oregon planks in the shed from years ago when the house was built, 6x2 or 8x2 if memory serves, and looking at them I wonder if laminating several layers is the only way to fly

I assume a single piece of timber would be plan A, taking into account Landyacht's flex-test and quality criteria.

Pretty close to 3000-3100mm for the timber section, and then stub axles outside of that to bring the whole assembly to about 3450mm overall width.

Hoping to stick with the standard (as far as I can tell) FISLY Class 3 dimensions, not that this will be real Euro style class 3

Thanks for the tip Hiko. I assume the scaffold plank worked out well?

the lamibeams you get here in aus are really stiff and poor quality,dont weather well being radiata. NZ has better quality plantation stock.
at that length i would be going 3 layer .2 tassie oaks and a a pine with minimal knots on top.maybe 290mm wide at the centre and tapering at the outer. 1 wrap of epoxy/glass to keep it clean and dry

Another question. I heard mention that Oregon might be an appropriate timber to use for an axle; might this be true?

Local timber supplier has tassie oak, nothing wider than 200mm though. 200x20mm plank is going for about $25 per meter...
