Optimal Wood Density for Lightweight Bodies Hi everybody! I've been reading this forum for quite a while and I've learned a lot! So, thank you all for sharing your knowledge. Now it's my turn to give something back. I haven't found any similar info about this on the internet so I hope it's helpful for you. Ok, let's get it started. The other day I was thinking that it would be great to know, how much would a finished body weight, (all cavities routed) prior to start working on a body blank. This way you could tell if the body blank still needs more time to dry or maybe the wood is just heavy. So, here's what I did: First, I took Terry Downs "Rev. D" Telecaster Template, and drew it in Google Sketchup (3D Modeling Software) with the right dimensions (I only removed the truss rod access for vintage necks from the model). Then, my intention was to calculate the volume of the body (with an external plugin) but I had serious trouble with it so, what I did was, making the body shape without cavities, and then on a separate model, I drew each cavity to calculate their volume separately. Look at this images and you'll understand what I mean: Ok, I hope you get the picture. By the way, there's one little detail. Cavities such as pickguard screw holes were so small that the plugin rounded the volume to 0 ml (mililiters) so I decided to ignore those. Please keep in mind that this model and also the volumes calculated are not 100% accurate but very close. Let's move on to the math part: Body Volume = 4739 ml Cavities Volume = 326 ml ----------------------- Total Volume of Routed Body = (4739 - 326) = 4413 ml (mililiters) Ok, now that we have that, we can see what's the density we're looking for in our wood. Let's say we want to have a body that weighs 4 lbs (1814 grams) or less (use another value if desired). Density = Mass/Volume = 1814 grs / 4413 ml = 0,411 gr/ml Density = 0,411 gr/ml = 0,237 ounces/inch^3 (if you want other units, check out http://www.digitaldutch.com/unitconverter/) This would be the highest density we should have if we plan to build a body that weighs less than 4 lbs (1814 grs). Now all you have to do is, take a ruler, measure your body blank, calculate it's volume (Width x Height x Depth), see how much it weights and then, calculate it's density (mass / volume). By comparing this density with the one calculated above you can tell if the body blank is still too heavy or just right. I'm sorry if I wrote this in a confusing way, English is not my mother language so, you'll have to forgive me Tell me what you think about this! Any suggestions would be much appreciated. P.S.: If this was posted before, shoot me!
