I've had the beta Magic-Flight concentrate trays for a while but little access to full melt concentrates, so I haven't used it a lot. This morning I noticed a little resin accumulation building up at the exit hole and I got an inspiration. A while back somebody mentioned heating up the LB and liquefying the resin that accumulates under the screen so you could drain it out, so I thought I'd try this:
That's one of the Magic-Flight super-batteries used for illustration, since I have a PA which is better suited to this. Basically, all I did was hold the LB like this with tray in position for about five minutes. I would have taken a picture of what I got this way but it didn't work out as nicely as I'd have liked. My LB has never been cleaned under the screen but it has been used a lot, so a lot of reclaim drained out and got all over the screen and my LB. I stopped it before it got too bad but no way was I about to post pics of that mess. Oh, everything gets pretty hot too. I didn't get burned or anything but it does get uncomfortable to hold.
This method works but needs some refining. I am hitting the resin right now and it tastes okay but not great, since it's reclaim. It certainly does get the job done, however. Unfortunately, it is not really full melt either, so there's a bit of residue accumulating on my tray screen.
(No, that's not my real serial number.)
