After reading sawhorse’s blog about his workshop I have found that I can use some advice on my own shop build. Hopefully I will start the new shop in the very near future. I currently use woodworking as a side job with the hope of moving it to full time in about 3 years. My question is do you think that a 20’x40’ building would be big enough to handle a full time shop (that is the size I am thinking right now).What advice can you give on dust collection? would an outside unit be better than an inside one. should I run the dust pipes in the floor or around the walls? Which building would be best I have priced the prefab metal buildings and have a material price if I build it myself. I can save a little money if I build myself but really like the idea of the metal building being put up for me. As you can see everything is still in the planning stage right now so all advice would be helpfull. Thanks for reading.
