It's important to note that you MUST clear the wood chips frequently while drilling the mortis. If the wood chips build up, it will generate excess heat and pressure which will change the final hole size as those wood chips press against the sides of the mortis. | It's important to note that you MUST clear the wood chips frequently while drilling the mortis.

Be aware, that the bit that provides the right hole size for briar, may be too small for drilling a hole in vulcanite or acrylic. You'll need to be sure of your drill bits before you start. | ||
