I know there's a lot of creative people on the forum that have made some very function tools and shop fixtures to make life easier. Hopefully this thread will turn into a resource of creative and affordable tool accessories for others.
I've been busy the last couple of weeks reorganizing and improving my garage workspace after 10 years and here's a few things I've come up with.
Mobile tool dolly with go-to tools that can be positioned close to the task at hand and capitalize on vertical space as I'm limited on horizontal space.
The small fab table in the forefront has proven to be very handy, lower height than other surfaces, portable for grinding plasma cutting, grinding, forming, etc. I also just built the base for the tube notcher with a space-save spare tire that are a dime-a-dozen at the wrecking yards.
Small forming dolly
Table with fence for the machinist base on my drill press.
Another dime-a-dozen item, Dodge diesel truck scissor jack modified for use with 1/2" drive.
