Very interested in getting a planer-thicknesser into my workshop (née shed) which already is home to a lot of tools, a compound mitre saw, bench sander, bench pillar and most recently a floor standing bandsaw. The weight of the latter, particularly as it is wheeled, gave me pause before installation, but I went with a long sheet of 18mm hardwood ply to spread the load over the t&g floor and joists.
The planer-thicknesser on the short list is nearly double the weight of the bandsaw, more than double once you add in the required extractor - at which point I start to worry about the entire floor construction. So...
Is the shed going to collapse under the weight? The shed is approx 4.9m x 3m, and the floor looks to have been prefabbed in 3 sections over the 4.7m length with joists of 45x70 at 380 centres attached (I assume) to a timber base of 100x50 joists at 530 centres. Those joists are supported in their centres (so approx 1.4m unsupported spans. It seems sturdy enough, but then there's quite a load building up in area (the bandsaw and planer-thicknesser/extractor will all be in one section, though the bench with drill and sander etc. runs along the opposite wall.
I have enough access to allow adding additional supports to the base around the heavy load areas (using Castlewood's neat deck supports - slide them into place and then adjust the height) and will add more (screwed down to joists) 18mm ply for the planer-thicknesser and extractor to sit on. Should that do it or do I need to do something more?
