I started at 20 with a makeshift jeweler’s bench in the hall closet of our one bedroom apartment.
Fast forward 40 years and I’m pretty fortunate to have a dedicated16x12’ room in the walk-out basement to contain my affliction. The workshop is the inner sanctum of my introvert shell where I can retreat to make noise, stink, or just sit and bask in the atmosphere to feed my soul.
Climate controlled (glowforge stays happy) with power ventilation for welding/plasma cutting and a deep sink.
There, I create, repair, and eviscerate either for useable parts or just to explore and understand the workings of a device.
The main focus has evolved over time from woodworking to primarily metal work - to now mainly art, thanks to the glowforge.
If I were to expand in capability it would be with 3D printing I think.
Someone is going to have a hell of a mess to clean up behind me.
