Well dear readers, I've not been to have a chat with either of my two colonies for several days. We nod to each other in passing when I go to feed the chickens but all the bees seem rather busy at present and they don't seem to have the time to stop and show me what they have been up to in the hive. Even if I sit on a log near to the hives they will usually hurtle past me with barely a glance. I guess they are far more skilled at running a busy hive than I will ever be, so I will leave it a few more days before I go and have a look inside again.
I've never used Hoffman frames. Always the standard type of frame with spacers. I've been making my own spacers for a while now with the 3D printer. I did have the idea of using different colour spacers for (for one example) knowing the age of the wax but I have never fully implemented the idea.
Since I have a considerable number of ordinary frames, changing to Hoffman style is not an option at present. So for the past two or three days I've been working on a slight change of plan with frame spacing. Back in the 80's when I first started with bees, all the boxes that made up the two WBC hives that I bought (complete with bees) had the remains of metal strips with castellations to separate the the frames. As each one eventually disintegrated I replaced them with plastic spacers on the frames. I'm now tweaking a 21st century equivalent - its plastic, its a continuous strip and its printed on the 3D printer.
Each box (brood or shallow) uses four strips - two per side. My 3D printer bed is 200mm x 200 mm so I have to print half of each one at 45 degrees to be able to fit onto the bed. I'm using PLA filament since it is cheap, easy and environmentally friendly.
The advantages I can envisage are:-
(1) - They don't rust.
(2) - They are not sharp.
(3) - They don't wait for you to look away before falling off the frame and into the grass.
(4) - They are not difficult to remove from a frame. The frame simply lifts off it.
(5) - At present they are loose (but secure), but they could be secured semi-permanently by double sided sticky tape if necessary.
(6) - Bees cannot get trapped behind this type of spacer.
It remains to be seen if the bees glue everything together with propolis and make these unusable.
I've put a couple of photos below showing the castellated strips installed on a new brood box. I still need to make one or two minor adjustments before I ask the bees to 'road test' them for me and decide whether they like them or not. I'd be interested to hear your comments too, in case you can see problems that I've not had the foresight to consider.
