Help with bookmatching

nicovlogg

Hey, so getting things in place for a little thin line build, and planning on doing a Bubinga top. Now I've got the wood, but not the skill to try and book match it. Is anyone willing to help with the process? Even some tips if it's not too difficult.

Step 1: what is your blank thickness and what is the thickness you would like to achieve after sawing/planing?

i have done it before with a bandsaw and a jig around it to cut the wood straight, my wood was 20mm thick, and i just carefully pushed it through to keep it straight, i didn't have much saw marks (lucky me) and just had it planned and drum sanded, came out nice, but you are gonna need a friend to help keep it steady if you go that route.

Knowing someone with skills is important.
Manny demonstrated the technique above to me.
Simple when you see it - but you probably won't think of it yourself

The right blade is also important.
The thicker the wood you cut, the fewer teeth per inch.
The spaces between the teeth are needed to carry away the sawdust.
My intuition went the other way - I incorrectly thought that you wanted more teeth per inch if you wanted a finer finish.

The blank's about 33mm. Will be 30mm after planing nice and flat, but yes - there's plenty there.

The finished caps are normally between 1/4" and 1/8", so I'm aiming at about 3-4mm.

Some kind of square angle jig to keep the blade at right angles?

33mm to achieve 2*4mm? You will be able to do this without bandsaw if needs be. You actually run more of a risk to take too much off of the cut line, so that the match deteriorates. It will be worthwhile to thickness since getting the blank flat will improve your chances of getting a straight cut with minimal thicknessing after.
The bandsaw just requires a large square block to get the cut parallel to the large faces of the blank. The upright face of the block should align with the cutting direction and be set up at the right distance from the saw.
Alternatively, without bandsaw, you take a circular saw and cut a groove in the center of the sides and ends of the blank. The deeper you get it, the better. This groove acts as a guide for the handsaw that you use to cut through the remainder of the cut. Sure, you will be sore; you will however not need more than 4mm for the whole cut.
