Hardwoods, botanically known as angiosperms, are deciduous and shed their leaves annually with temperature changes. Softwoods come from trees botanically known as gymnosperms, which are coniferous, cone-bearing, and stay green year round. Although a general pattern, softwoods are not necessarily always “softer” than hardwoods, and vice versa.
Usually ducting is well covered and one of the first things considered, however, most people initially neglect clean up when designing shops. With growth, I have a very cluttered shop that makes pulling shop vacs around frustrating especially if you’re at the wrong end of a 5m flexible hose without having to struggle with the vac (the practice of in no doubt exacerbated by those ridiculous vacuuming ads on TV). As my setup is retro fitted, it may not be pretty as it is ducted overhead, but it is productive. I have a centralised heavy duty ‘shop vac’ (rigged with a Dust Deputy) and 50mm stormwater piping radiating to selective parts (corners) of the workshop. I use 50mm water diverters to act as blast-gates to control the flow of air (I have a bank of them running down one full side of the workshop spaced about 5m apart). When I need to clean a part of the shop I plug the vac into the appropriate overhead vent, organise the diverters and attach a 5m flexible hose to the working end. I have the vac on a remote (one of those that control power points – all my dust extraction is controlled by these – after modifying any proprietary mag switches) and I can vacuum any part of my workshop without having to go and manually switch the vac on. I have bought some cheap off market flexible hoses and spread them at the extremities of the workshop. Each outlet will accept the hose. Hint – I bought a fairly low end 3D printer ($800 (Aust)) and I can print any sized coupling to accommodate all those non-standard ‘shop vac’ hoses/fittings to accept my proprietary shop vac accessories. Duct tape is now reserved for the few threaded non-standard couplings.
Sanding concave molding doesn’t have to be difficult. Find a deep socket that fits the contour of your molding. Wrap a piece of sand- paper around the socket and hold it in place with your fingers. Your sanding will be uniform and the delicate edges of the molding won’t round over. — Eric and Cheryl Weltlich. In this video, Travis talks about his favorite sanding tips.
