    Default what a waste

    I started off with a 50 mm thick block of Brazilian Mahogany cost me £40 re-sawed it carefuly into ten 4mm slices so 10 mm = 20% turned into sawdust.. I mark out and trim the edges to ukulele shape and 25% of the "off cuts" end up in the bin, now with 45 % gone I take the ten 4mm slices to the thickness sander and thickness them down to 1.8mm thats another 45% gone into sawdust...so in my calculation i've ended up with only 10% of the original block of wood and I still have to trim the edges and cut out the sound holes and dovetail pockets..and if it was a cutaway even more gone
    Can someone please double check these figures.

    No wonder it takes two of us to empty the full dust extracor bin.

    If you can believe that moving images and sound, can fly through empty space across the universe and be seen and heard on a box in your living room ?.. then you can believe in anything.

    Your reckoning aside, Ken … this is a very disappointing aspect of woodworking with 'wafers'.
    I can only dream of your efficiency. I cut everything (top, back and sides) on a specially jigged TABLE saw... talk about waste. My band saw is not up to the task of re-sawing billets, so I buy in DAR boards or rough sawn planks, and this allows me to minimise waste just a little. If I end up with more than 30% of my wood after the initial re-saw, I consider it a major triumph. After planing and thicknessing there is not much left, cents in the dollar-wise.
    I have the added aggravation of being sawdust averse, so adding insult to injury, I usually end up liberally coated from head to toe in a small percentage of my wood purchases.

    I can't remember if I posted this here or not, found the most flawless 2x4 stud after years of picking through Home Depot's pallets. Did a rough calculation, decided to go for it. Cut it into two lengths, resawed the one, took two sheets off the other, laminated them together for the top back and sides. The rest of the solid wood was used to make the neck. Other than the neck blocks and the brown bits, I made up a Martin 00 sized guitar.





    To say the least, I was concerned at various points whether I overestimated how much wood I had to use. I need to finish this one, just need to do the frets, mount the tuners and bridge. Mind you, cost me less than the Mahogany.

    It gets worse man.....all that work of cutting, thinning, trimming is not value add labor from a Lean manufacturing point of view.

    You wasted all that time spent wasting all that wood!!

    We need a stiff razor edged tool to resaw with. One cut, perfect surface, no muss no fuss, no waste. And cheap.

    Ö. and all of those larger limbs that get left on the forest floor or chipped for composite sheeting. A lot of uke sized wood is squandered and left to rot, or fuel wild/bush fires. Anyone for a chipboard ukulele ???

    Actually a chipboard out of exotic woods might be interesting.

    Well although I agree with all said here... as I tend to think of these things as I am re-sawing sanding and all that...I disagree to a certain extent.

    Waste is when you throw it all away willy nilly and do not use it.....However, if you put waste into a system that feeds on it....Like... feed it to worms or mulch a tree, compost it down, then it becomes food not waste....A dead tree on the forest floor is full of life and in the proper system nothing that breaks down and does not pollute the system is waste...It is food. Being that I am also an Organic Farmer I am just feeding the soil and the worms which in turn grows food....

    It still sucks but I dare say it is just as important to feed the soil as it is to make an instrument. At least it is a natural substance that is non-pollutive.

    Just another way to look at it anyway!
