Here's a bit more in-depth information. https://amzn.to/3qA7Wsl? -- WOODWORKSHOP The great jigsaw blades, which cut without tearing, are apparently only available in sets of 18. Here's the link https://amzn.to/2Z4ENtS In the wood workshop, I can't manage without a biscuit joiner. I use the inexpensive solution from Einhell https://amzn.to/3mrdIKG? A pile of 20 mm biscuit dowels comes in a practical case. You can never have enough of them. https://amzn.to/37rux3D? Not exactly cheap, but worth the price is the GCM 8 SJL compound miter saw from Bosch. I cut wood for smaller boxes entirely on this saw. I won't be giving it away again. https://amzn.to/3msHiPU? For precise cuts, you need to adjust the saw angle. Unlike other products, this LevelBox has a real battery (AAA instead of CR2032) and doesn't require a new battery as often. A tool I can't live without. https://amzn.to/2J143Nc? You can find the great textured paint for refining your enclosures at the following links.
