When it comes to laser materials I know personally I use a lot of 3mm ply, usually birch.
But when it comes to purchase I only ever need 5ish sheets at a time. Shipping for me is a pain because am only at home in the evening and getting a 600x400mm sheet of ply to the space on my bicycle is a challenge.
I was wondering if the space would be interested in buying in bulk and selling to members on an honesty system.
Hobarts sell 600x400mm 3mm birch for £3.49 each, for bulk orders of 50 or more this drops to £2.96.
Lets say the space puts a small fee on top %10 to cover any delivery or cost towards maintaining the laser cutter.
Maybe also make a space for off cuts which are free to use.
I know there is more in this world than 3mm birch. we could do a survey to get an idea of demand?
