Material for furnace filter trees


ChrisNH's picture

By ChrisNH - Posted on 10 April 2009

I need to make some pine trees and would like to make some furnace filter trees. The only loose furance filter material at Home Depot was a large sheet of what looked like a kind of blue sponge material. Is this the right stuff? I  watched  Joe Fugates second scenery DVD video which  showed the material already cut and teased apart, so I was not sure what it looked like "on the shelf". Likewise, most of the print articles I have on the subject dont show it in its unaltered state..

Thanks,

Chris

Nope the blue stuff is not what you want.  The stuff you need is brown.  I wish I could remember the name of it...Joe knows it.

I'll google around and if I find it before you get an answer I'll post it.

I checked the thread in question and saw the pics...that looks like the blue stuff and it looks great.

The name I was trying to think of was Hogs hair!

I think we may be talking about the same stuff?

The stuff I use (and that Pete of Canyon Creek Scenics uses) is a lighter blue color. It comes with a square 3/8" (or so) mesh on one side you need to tear off.

I get mine from Wallmart.  It's about 2' x 3' in a palstic bag in the hardware section for about $4.00.    I have read in other posts on this subject, that not all Wallmarts carry it in all areas or all the time. In some areas only some of the Wallmarts carry it so look around if you can.

Thanks.. I will check them out. I think there is something else the wife wants me to get there which will give me the excuse.

Wally didnt have it..

I ran out to Lowes during a time both kids were asleep (read, when a small miracle occured) and found some blue material with hogs-hair style batting. It had a square grid material on one side like Charlie described, so I am thinking its the same stuff. I am excited to move forward with this. Now I just need to find a little time..

The next challenge will be figuring out how to cut strips from the shingles I picked up that can be rounded for trunks. I really wish I had a band saw or a mini-table saw.

Chris,

Do you have a table saw at all?  If so, does it have a zero clearance blade insert?

For anyone who doesn't knwo what I mean.

What I have is an insert for my table saw that my father made out of a piece of oak.  It fits perfectly into the blade opening in the table..  Once the wooden insert fit the opening he clamped it in place and with the saw running he raised the blade, cutting up through the wooden insert.  The result is a thin slot just the right size for the blade to protrude through.

With that insert in the table saw and using a push stick I can rip thin strips without them slipping in next to the blade.  Still not an easy task, requires care and a face sheild, and as you say, much easier with a band saw, bench scroll saw or mini table saw.

Regards,

I do but its not especially good.. its one I have on loan from someone who doesn't have room for it right now. I would not trust it to rip anything that tightly, even with the insert you describe.

I do have a jig saw which I am going to try to use along with a carpenter's square. Hopefully that will give me "good enough".

I also have a dremel which could probably be used with a cutting bit and the router adapter but it generates so much torque I would be hard pressed to keep it online even with a jig. I could maybe clamp it with my rotary wood bade to use as a table saw.. but that sounds too much like the opening line of a Darwin Award..

Chris, a japanese style pull saw will let you cut the shingles into strips without costing you an arm (literally). Rube Goldberg shouldn't be mixed with power tools, imho.

If you dont' have a japanese (pull) type saw, they are well worth it to your tool box  - under $20 at sears, and great for lots of work, Here's the one I got a few years ago, still going strong, and cuts surprisingly quickly. It shouldn't take much to cut up the shingles for trunks.

Otherwise for your table saw, you could also make a zero clearance insert from scrap plywood (mdf is great for this). Use one piece flat against the top screwed to another piece that can be clamped to the fence, or a piece big enough to clamp to the table top. Bring the blade up slowly until you just cut through it and get to the depth you need.
