Merbau wood

Hi everyone,

I am keen to use a single solid straight piece of merbau wood for a short crayfish gun:
https://www.daf.qld.gov.au/business-...er-trees/kwila

I've read various reports that it floats, and others that it sinks. I'd keep the blank and barrel large and bulky, fit the hardware, then shave off slowly till buoyancy was achieved, but I'm worried it would be doomed from the start if the piece I got was too dense and it sank straight from the start. Obviously different sections and cuts will be variably dense, and some may float or sink, but I don't know how to tell this till I cut a block and try it.

Any suggestions or tips?

Thanks

I've searched and read this and other forums, and obviously guys build some great looking guns out of it. Just worried I'll purchase this wood and not be able to use it.

Re: Merbau wood

The good news is that you want a Crayfish gun to sink right? The bad news is a short Merbau gun will sink. Even if you keep it fairly bulky and use lighter hardware it will be on the edge. I couldn't see anything less than 120cm total length and quite a robust volume with no reel and a light shaft and light mech being anything but a real sinker. but that might not be a bad thing for a cray gun?

Re: Merbau wood

Thanks for the replies.

Behslayer, the blocks I can get are 90mmx90mmx2400mm. If I kept the barrel at 70mm or 80mm width x 1050mm length do you think it would float a 90cm long 7mm diameter stainless shaft with neptonics reef mech? Are there positively buoyant handles that would help float that end against the weight of the mech and trigger etc..?

question related to mebau , heavy wood gun no lead VS light wood gun with extra lead ,recoil behavior of both in same environment considered same design and shape .

potentially you could adjust weight with ballast except that here you would not use lead but could use an expanding foam or cork, neoprene, anything light...
