Tim said: > Like Allen, I prefer the black Pierco 1 piecers. I think the plastic might work in certain operations but personally I do not know of a single commercial beekeeper in my area which uses all plastic. I think you and I discussed the issue before on BEe-L but if not I might add a few points . The first is breakage. Ends still at times break off then you have a junk fully drawn frame. Maybe you have a solution for broken end frames? I can repair a wooden broken end right in the bee yard in a few minutes. Properly prepared ( good fit , nailed & glued) and *not old* wooden frame ends are pretty tough but we do break a few being honest. Next the one piece plastic frames need spaced when used with a division board feeder. Not such a big deal when using 10 frames and feeding the bees through a hole in the top. Slide 10 plastic together in a brood box and then slide ten wooden frames together and note the difference. Next although there are methods to mark black plastic frames I easily put the *year* a frame is placed in service and rubber stamp each frame with my bee farm name. I can tell at a glance the history of a frame. Theft of frames in almonds is common.( personal experience) Next if I see a comb I want to change to foundation in the bee yard I can hit the frame with my fist and replace with a new sheet of foundation. I carry the new foundation in my side box and keep a box for the old foundation in the same side box. One pull through the groove with my grove tool is usually enough to insert a new foundation. In field repairs make sense. Putting off till tomorrow in the bee business leads to huge stacks of equipment needing repair! I renew the old plastic foundation over the winter. I do not bring the frames in as the majority of beekeepers do and create this huge stack of frames needing repair. I repair in the field most of the time and only bring in the foundation. Once scraped usually around 75 frames will fit back into the original box the came in. How many one piece plastic frames are in your waiting to be repaired pile Tim? I also have the option of keeping the fully drawn brood comb and using a new wooden grooved frame. usually you get a couple mashed wax places but I have done many. Also plastic one piece in new made up singles shift when moved to the yards and lids need removed and the frames aligned. Ok Tim try and convince me why I would be better off with all one piece plastic frames in your opinion. Allen might help. I try to keep an open mind on these things. bob *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
