Such a nice mild day following yesterdays downpours so repaired the wooden raft my bee equipment shed sits on, a pair of 4 x 2 bearers had started to rot on one end of the shed base. Two and half hrs later repair all done and timbers creosoted. Though the raft is sat on concrete pads and there is good airflow underneath , one corner/end has a build up of leaf matter/detritus that had gone unnoticed causing the rot.
That done I decided to make a start on some clear insulated polycarb crown boards, routed a groove into some 3 x 1 redwood to make up 1/2 doz crown boards.
Polycarb isn't very cheap but found some unsued 5mm x 560mm sq ceiling light defusser panels on ebay, working out at £7.60 a panel was a lot cheaper then other offeings I found. These I cut to size this afternoon ready to make up the boards, along with some 1200 x 450mm x 50 celotex. All in all 6 insulated boards which will take two or three hours to make will come in at sub £16 each.
Another advantage of a crownboard to look through is to assess the spread of fumes during vaping as well as checking on the colony without having to disturb them.
