Sawdust drop box
I'm shortly going to begin the construction of a large unit to store all the kids toys in. This is going to be made from moisture resistant MDF. If you've ever cut this stuff you know what a mess it makes. It gives of a very fine dust so as well as breathing protection I need a better solution to collecting all that dust. I don't have room for a proper dust extraction system but a vacuum does a reasonable job of collecting dust from my hand power tools. In order to make the vac last longer and not require bag changes so often I'm knocking up a quick drop box that goes just before the vac to collect most of the shavings.
So here's a pile of materials, some ply, wheels and hardboard:
Cutting pieces to size with circular saw and homemade guide rail:
Boards cut to size:
Test fit and sinking some holes:
Some silicone in the joints to make it air tight:
Once I'd screwed together I got silicone squeeze out all along the joints - hopefully means their airtight!:
Cutting the hole in the top 'shelf':
Top 'shelf' fitted:
Lower baffle installed:
Batons and hardboard screwed and drilled in place:
Progress so far:
That was after a couple of hours last night - much of which spent making decisions >:)
I hope to finish build tonight, but we'll see. For info dimensions are 500x400x600mm (wxdxh). This is max I could have for the space I've got. I could have left the vac off the top and made it taller but I want to fix vac on top and only have to move 1 object.
Should just thank Mike Garnham at UKWorkshop for the idea and inspiration behind this 
More to follow.
