Hiya, Yep to bend that tight radius I thin down the area to 1.5mm (sorry I use millimeters/I'm belgian/European) The rest of the sides are 1.8 à 2.5mm depending on the wood. I use a stewmac bending iron. With a sponge I apply water on the sides just before bending them. I don't soke them in water overnight! The trick is to select good bending maple for the sides, sorry it's a hard one to explain. Some maple bends better than the other. Time is your friend when bending these tight radius tele sides... Set the Iron not to hot or you burn the wood and it will crack!!!
I use Reverse kerfed lining to give the sides some more strength. I glue some extra wood inside the sides where the Strap Button screw will come, so the screw has some grip to take the weight of the body.
Back and Top are just flat and are 5mm thick. Unbraced.
The middle beam is Movengue (tropical wood) 100mm wide. Total thickness of the body is 55mm (10mm thicker than a standard tele)
Any more questions? Just fire.
Best,
J.L.D.
