I haven't heard of any being scheduled.

If you would like to have one you are welcome to do so. Most of us just set a time & day, post it on the boards & tell people if they need to bring anything.(ie: food, drink, etc...) It doesn't have to be an all day thing either. It could be half a day, morning or afternoon. Most people bring the supplies they will need (elastic, glue, tools) but if they are going to need anything they don't have they will usually post asking if anyone has one they can bring. It's really up to you how you want your armor party to go.
