I’m brand new to cnc carving and decided to try the Japanese style of burning the wood first (Shou Sugi Ban).
I started with planing the wood flat, torched with MAPP gas, cleaned it up with soapy water, and started carving.
At some point, the wood ended up cupping pretty bad and I ended up with the the v-bit embedding pretty deep into the top and bottom, and skimming along the middle. It was obvious what was happening right away, but I let the carve finish just to see how it’d turn out.
The enormous H ended up being a bad design decision considering the bit’s I’m using and how I built this with a vector image editor. The pattern around the H was created from a bitmap image converted to a vector … the little problems ended up being far more noticible when the carving started.
There are some very nice clean edges along the top, and then things just go south towards the bottom of the board.
I really like the look and texture of the burned wood style. The carving really pops out with that black background.
I want to find a way to work with this style, but need some advice on how to overcome the challenges involved with the wood cupping like it did.
