The trickiest part to consider for this project was choosing the right wheel.
Because the VADHOLMA has wooden legs, it was determined that ‘bolt hole’ castors would work best, with no greater than an M10 bolt size. The reason for this is to ensure that the wood inserts that hold the castors would fit well, and the leg would remain stable at the bottom. Point to note, the leg width dimension is approximately 35mm x 45mm.
There are other factors to consider when choosing the right castor wheels as well – wheel diameter, overall height, material and load capacity. In the end, we chose wheels that had individual load capacity of 70kg, and total capacity (of 4 wheels) of 210kg. That is plenty, bearing in mind the island weighs about 60kg. We went with a rubber wheel so it can grip the tiled floor. We chose 2 braked wheels rather than 4 because the non-braked wheel is a little less obtrusive.
