Looking good Dave. I hardly ever use my platen, but yeah a bit of an aggravation. Would recommend putting a "back splash" behind the machine - sparks and grind debre will be hitting that window frame and accumulating (faster than you think).
Another tip - always check for smoldering when you shut down for the day. Debre build up can hid a smoldering spark and later warm things up where you don't want it. I keep a squirt bottle handy all the time.
