My trade offs have come as a result of location (SE Asia) and price (everything is expensive here!)
Because of location, I couldn’t get material in the length I needed, so ended up with a machine that is just capable of being shy of a full ply sheet
Because I have to freight in even such items as screws, switches and wire, it has cost an absolute fortune to make. And if I forgot something, it set me back weeks. So, I have spares for everything.
Before it ever made its first cut, I wanted to redesign it. The original designer made some engineering howlers.
My next machine will be made more from what is available locally.
