Dust extraction advice - wood and metal
Hey there everyone, I am hoping some of the experienced guys here may lend me some advice on the best way to go on setting up a suitable dust extraction system. I have read many of the posts including stickies on this site and really appreciate the amount of expertise and willingness to share.
my workspace is basically the corner of a larger shed. It’s a ranbuild typical shed, 11m x 9m 3m to the eves. It is our car storage as well as a small tractor, garden equipment etc. So I have an area about 3.5 x 4m that I use as my workshop. It is not enclosed within the shed, just bound by bench and machinery. My most common activity is knife making so grinding on a belt grinder blade steel but also handle materials such as wood, micarta and G10. I do also have a bandsaw and wood lathe that I would like to use a lot more but don’t currently since it creates so much dust covering everything in the shed.
Where we live is acreage and noise generally no issue. Venting dust directly outside also would not be an issue. I am currently thinking of setting up something like a DC3 or DC7 with pvc ducting to each machine. Under the grinder a bucket type trap with water in it so inlet straight under grinder into bucket and air pulled out from side of bucket to the motor just like a cyclone I guess to limit chance of fire ( I also grind titanium). I would then outlet from the motor directly outside with no dust collection or put motor with dust collection bag outside.
Could I, instead of having water trap below belt grinder go straight to a normal cyclone which could be used for other lines to bandsaw and lathe (blast gates used to allocate air to each machine when in use) which would collect much of the dust and then just vent finer dust directly outside? H&F also sell a metal/wood extractor DCM-200 but I feel this would be pretty messy for fine dust from bandsaw and lathe? Any one have one of these and can offer advice on how well it works?
thanks and please ask questions if it helps to assist advice.
