I have been using a crosscut sled for a while now and the one thing that's not too good about it is the difficulty of dust extraction. Having thought about it for a while I decided that a box that ran the length of the sled with a hole in it for the hose would be a good solution. I initially thought that I would make it out of perspex and use some brush draught excluders on the bottom so I could still have a seal with a piece of wood in place to cut too. I went to the local DIY store and would have had to spend around £40 for the bits I needed, I thought this was a bit much so i came home and had another think. The following design was built from bits and pieces I had around the house, its a bit rough but it does work so I'm happy
2 CD boxes
Offcuts of wood
Instant grab adhesive
Foam - I got mine from an old memory foam pillow!
