Prepping Rough Planks for Solid Bodies

Prepping Rough Planks for Solid Bodies

by John Calkin

Published online by Guild of American Luthiers, October 2021

 

There are plenty of places online where we can purchase prepped electric guitar body blanks. But who can refuse free wood when it is offered? Several rough planks of 2"×9"×12' poplar came to me out of the blue. They had been painted on two sides, but so what? They had spent years in a dry barn. I cut them down to 6' to fit them in my little pickup truck, hauled them home, and stored them in my mower shed for two more years.

I have been working on electric ukuleles, mandolins, and mini guitars, and that is where the poplar is destined to be used.

The first step was to cut a plank into 15" lengths using a sled on the table saw. Though it looks like the plank will be run against the fence, there will be plenty of clearance after the cut is set up.

Two pieces sat evenly on the saw deck so I proceeded to run them through the drum sander, first the humped side and then the cupped side.

One edge was sanded flat (but not perfectly) on the 6"×48" belt sander in order to run it evenly against the table saw fence while the other side was trimmed clean and perpendicular to the faces. In this photo, the second edge is about to be trimmed.

That's as far as I will take them for now. They are shy of the 1 3/4" thickness used for most Fender electrics but plenty thick enough for smaller solidbodies. When the time comes, the shorter length will be sliced up to widen the longer piece as necessary, making the bit still covered in red paint irrelevant.

Once joined the blank may be thinned even more to accept a top of figured wood, but that lies in the future. The three blanks off the board that rocked too much on a flat surface would still rock after thickness sanding, so they will get a slightly different treatment later. ◆

’Way Down Upon the Amazon River

There are many South American exotics that are perfectly viable species for instrument building. It’s hard to get luthiers to go along with that, however. Everyone wants perfectly-quartered Brazilian rosewood.

The reason I mention alternative woods is that the true Dalbergia nigra, the Brazilian rosewood that luthiers love and would sell their cars and dogs for, is getting to be very hard to find. We at Luthiers Mercantile found this out the hard way a few years ago, in much the same way that the Martin Co. did. You have to pay for the wood up front, which puts you at great risk; you just have to trust the person you are buying from.

Some Alternative Lutherie Woods

Some Alternative Lutherie Woods

My name is Tom Ribbecke and I’m on the staff of Luthiers Mercantile, pretty much the technical guy there. What I’ve brought to this presentation is based on my years of building and repairing guitars along with my four years at Luthiers Mercantile. I’m not a botanist or scientist, no more than any of you are... except for the botanists and scientists who are here. (laughter) I know there are many here as I caught Nick Von Robison’s workshop earlier today. So when I was asked to do this presentation, I thought, what could I do to focus on the alternative woods situation which is pretty much on all our minds these days? I’ve brought woods which have come up in my discussions with customers, things that we sell, and just about anything I could get ahold of on short notice.

When I look at materials, and people present them to me, I see things in blocks and 1" thick material and it’s hard to make judgments on what will sound good. Most guitar makers, like myself, like to hold, fondle, mutilate, and bang on the material in dimensions that are appropriate for the guitar. So this is what I’ve brought — woods of many species that could be used or considered for guitar building in appropriate sizes and thicknesses. I’ve brought some things that are commonly available, some not so available, and some which might be considered exotics. Many of these I’ve lacquered — usually with a lacquer gun in one hand and a phone in the other. The lacquer will give you an idea of the color of these materials.

With regard to the problem of Dalbergia nigra and related Brazilian rosewoods: True Dalbergia nigra is scarce because most of what little remains is being processed into veneer. I’ve worked with a very active importer of Brazilian exotics for several years and have seen crates containing thousands of feet of beau­tiful nigra, but it was all veneer. Occasionally he will run into a farmer with some miscellaneous trees or old logs of true nigra but that is rare.

With the purchase of veneer he also has the option of buying backing boards and nigra lumber otherwise unsuitable (usually too hard) for slicing. I’m able to select guitar-quality boards from his shipments and resaw sets but there is never enough to meet the demand.

As far as other Dalbergias from Brazil being substituted for nigra I’ve seen two that are very close, and to the unfamiliar, almost undistinguishable.

Western U.S. and Canada. 37 lbs/ft³; S.G. 0.59.

Heartwood pale red-brown with clearly marked growth rings. Straight grained with fine, uniform texture. Low stiffness, low shock resistance, and only medium bending strength. Very poor steam-bending classification. Dries fairly rapidly with tendency to distort. Kiln dries well but produces softer wood. Small movement in service. Very easily worked but knotty material is a problem. Difficult to harvest, moderate price, limited supply. Finishes well.
