These kits are laser-cut from 0.8mm plywood (therefore the pieces will have a dark sooty edge). We recommend using a good quality PVA glue for construction. Each kit consists of six pieces with laser-etched planking plus overlays for the external bracing. The internal structure slots together and includes a small square piece to hold the top of the chimney stack square. This can be painted black or glued further down for a hollow stack – just be sure to use the same external etch line as a guide on both sides.
An instruction sheet will be available in due course, but you should find the kits fairly simple to put together – just have a “dry-run” to make sure you’re happy with how the parts go together before applying glue.
