This bird table was a customer commission. The base and table are made from 20x40mm steel box section. We used 25mm square box section for the main leg and roof support. Plywood and oak were used for the roof, which was then covered in roofing felt.
The table base has securing brackets fitted to the internal corners. Pegs secure the table to soft ground. Alternatively it can be screwed down on hard surfaces. The underside of the platform has hanging loops, so that bird feeders can be attached.
