As some may remember….My Grizzly Bear made it into “The Lair”.
It was a potentially dangerous and harrowing trip….
With my G0458 18” Open Ended Drum Sander resting comfortably and all cleaned up and ready to perform….
I plugged it in, flipped the switch…. It is alive….
For about a split second…. then the fuse blew!!!
Yeah, I said FUSE…. all the circuits for “The Lair” are fuses!!! ;^(
Short story long…. There is only one circuit that I can run this beast on, as it requires a 20A circuit.
That ONE circuit is used to run my “Hot Rod” HF 2HP DC. Sooooo, there is no way I can run both at the same time…. A drum sander MUST be hooked up to dust collection, especially when being used in a basement workshop!!! There ain’t no way around that.
What to do, what to do…. I decided to lubricate my brain, with cold ones, until a solution presented itself…. That may not have been prudent, as I ended up with a hangover, because the solution was elusive!!! After the fog lifted, it dawned on me that this machine has a blower for dust ejection!!! However, the OEM bag filter is really just a dust cloud generator…. A better solution there must be…. More brews were consumed (I didn’t learn my lesson, yet!!!). Then I had a brain storm or perhaps a brain fart…. Maybe, just maybe the blower was strong enough to incorporate a Thien Separator. The only way to find out is to build one and see…. That and if it wasn’t up to the task, I would then use my Shop-Vac for added muscle. Now I’m psyched. I have a potential solution.
I gathered supplies, for a “less than conventional” Thien separator….
Since the sander will produce fine dust and the plan is to use this without a Shop-Vac, which has an existing HEPA filter, I wanted to incorporate a HEPA filter into the design. That meant a large “separation chamber”.... hence two 5-gallon buckets, with a Thien baffle in between and the filter in the top “separation chamber”. Time will tell, if this is brilliant or BS!!! Should I need to use the Shop-Vac, the extra HEPA filter will help save the Shop-Vac.
I’ll let pictures tell most of the construction story….
Go ahead and ask questions…. I will try to provide answers!!! ;^)
Cutting out the Thien Baffle, from 1/4” ply:
Inlet using 3/4” & 1/4” ply:
Inlet installed & baffle in place:
Visible in the above picture is the outlet (uninstalled).
I used 2” PVC male & female adapters….
screwed together like a bulkhead fitting.
Basically, I hung the filter from two 6” bolts, secured with wing nuts.
Problem being, I needed 7” bolts, so I did some “improvising”.
In this next picture, of the “pre-assembly”, you can see the “filter hanger”....
Black piece, with wood block & two long bolts.
Pieces-Parts before assembly:
For additional support for the outlet and filter….
I cut a 1/4” ply circle for the top of the bucket.
If need be, the Shop-Vac hose will connect to the PVC Outlet.
Thien Separator, top assembly:
Final assembly, installed:
With construction completed, it is now time that I go get another cold one!!!
Y’all are gonna have to wait for the results….
