Today was a good day for progress…...I have a semi-homemade low budget drum sander setup in the basement shop but the dust collection sucked…..or more correctly, didn’t suck…..
You can see the original setup in these 2 earlier posts:
Out with the old – in with the new:
The new version has a 4” dust port hooked up to the dust collector – I still need to do some plumbing in the ceiling to reduce the amount of flex hose, but that’s not a major issue.
The build started (as usual) with no solid plans – just a squared up 2×4 with slots cut into the ends to wedge between the cast aluminum end supports of the sander and then rip bevels on both sides. I didn’t photograph very well, but those vertical supports have a web of cast material that the 2×4 locks into:
I was really struggling to figure out how to put the second angle into the design so it doesn’t just end up being a pyramid – then it ocurred to me that the beveled cutoffs from the 2×4 would be the exact angle needed for the second angle:
To get the clearance necessary for the 4 ” port, I cut an arch in the 2×4 to get max air flow – also shows rig with access door open:
With the door closed:
I would have preferred to have the dust port on the in-feed side, but after some debate, it went on the out-feed side because this allows cleaning the drum without shutting off the rig and the dust collection will pick up most of the debris. Paper changing is the same as the stock shroud.
There are no mechanical fasteners, glue or otherwise holding the shroud to the drum sander.
Initial testing indicates a 1000% improvement! I find myself using the drum sander almost everyday so this was an essential improvement.
I should add that with the sled design I have, flatting twisted (oversized) stock is a huge bonus for this setup….... I have less than $100 invested….gotta like that.
Got a new camera recently – so here’s the bonus panorama shot of the shop….........
Re-routed the dust hose – minimum length of flex hose:
