I've done a little more to the workstation I'm building in the garage. Today I went to B&Q to pick up a solid beech worktop. Putting a section in place gives a whole new perspective on what the finished station will look like!
Just at the right edge of the picture you can see the lower section for the mitre saw. I'm still toying with the idea of allowing this to slide in and out to allow for the slide to work and yet be stored away without it sticking out too far. The white pipe you can see it for dust extraction. I have a nice Karcher vacuum cleaner that will attach to the end of the pipe underneath and then I'll find a flexible hose to go from the top of the pipe to the saw.
