Hi Francis,
Welcome to our community! Indeed, getting into woodworking of any kind is super fun and useful!
I’ll give it a shot; by no means my explanation is complete or correct, just my personal opinion really.
A Makerspace to me is a place where a community of people can come together learn how to use materials, co-create, share resources and knowledge, work on projects, network, code, build, be creative, or just hang out for a cuppa… open list really. We emphasize that we are not a business, we are all volunteers.
My favourite “thing” about SLMS is the community of like minded people sharing knowledge and making sure that machines and tools are operated safely.
For example, I always wanted to learn how to weld, but never really had any chance to do so. In order to weld at SLMS, you will have to pass a little workshop that we call inductions where another member with lots of metal work experience shows a small group how to weld safely and proficiently (well, it takes some practical experience to make MIG welds “look” nice, but everything I stuck together is still stuck together 
Same applies to Lasercutting, CNC routers, 3D Printers, sewing machines, vinyl cutters … the entire woodshop and so on. There are lots of machines that could potentially kill you (not an exaggeration, the metal lathe is not a joke!) - and it is reassuring to me that there are people with so much more experience than me that are always happy to help out or give you advice.
From my (obviously biased) point of view, to learn woodworking, a Makerspace is ideal. There is no agenda, just having fun, sharing knowledge - all in your time - no rush, no curriculum, and dare I say - the members fee is a no brainer, if you shop around other co-working open workshops.
Hope I gave you a little overview of “what we are”, feel free to come to any other event that fits your schedule. Check our calendar here on Discourse for other events that are open to members and non-members like Electronics Night (every Thursday evening) or Craft Social which happens every first Tuesday of the month. Open Evenings happen every other Wednesday, so after tonight, the next one will happen March 8th.
See you at the Makerspace,
Mark
