« Part 32: A Grizzly In The Lair.... Part 33 of Dungeon to Lair: That's the plan at least... series Part 34: A CL PC Posting & an afternoon drive »

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:

Filter installed:

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….

Very cool Randy – I’ll be interested to hear how it works! Very creative for sure…...are you sanding yet? :)

-- Jeff - I have not failed. I've just found 10,002 ways that won't work.

If it works, I will call you a GENIUS.

Bill,

I don’t want to wait for the results. I am old, waiting isn’t always an option for me.

Monte,
I promise that the wait won’t be tooooo looooong.
Now then, with that said…..
It may or may not be worth the wait!!!

i have no doubt that this will work son
or that you will keep at it till it does

have you considered bring down a 12 amp extension cord
from a 20 amp circuit upstairs

the fridge should be on it’s own circuit
so you needn’t worry about that going out

Thanks Dave.

Roger,
Believe it will. I may just need to tweak the separator. Either way, it WILL work with a Shop-Vac.

Eddie.
I’ll try to hurry the test, so that you could benefit from the results.
Do yo have a dust collector??? If so, that would be easiest!!!

Thanks, for dropping in everyone!!!

I gotta get back to lunch & then work….

The dust collection setup will not work right.
Send it to me and I’ll send you my dust collector.
A broom.

Randy if that works, it may work for the Dewalt 735 as well. Not that I have one, but I’ve heard about its dust blower.

William,
Shipping would make it prohibitive….
Looks like you are stuck with using the broom.
Just be sure that Doe, Candy, Nikki nor 74 are in need of it for travel!!!

Bill,
You may just be right…. (I can’t believe my ‘putter just typed that???)
The DW735 does have a rather powerful blower…
However, my DW735 is hooked up to my HF 2HP DC, so no need….
But it may be a good experiment, although the planer is more chips than fine dust….
So a bag/filter isn’t as hazardous as with the sander.
