Resize A Furnace Filter (on the table saw)
HTML-код
- Опубликовано: 7 окт 2024
- I need a specific size filter, and the one I have is the right width, but it's twice as long as it should be. Of course there are other ways to do this, but I thought it would be interesting to try it on the table saw.
Even though I did this and it worked well, I don't recommend that you do it. I'm willing to take responsibility for my own actions, but can't be held accountable for the stupid things you choose to do.

Aren't the cardboard sides edge glued into the filter media? And updates on how well the duct tape actually sealed and held to the filter? Swell idea.
Great tip, Thanks, John
My new K&N won't fit in the airbox, off to the lathe! Thanks John
I snort laughed at this!
This is exactly why I watch all you channels John..... I always say "shit.... why didn't I think of that!!!" This would have been useful when I was building my shop dust filter .... but I didn't think of it!!!! Thanks
Thanks for confirming this can be done! My furnace has hard to find size filters and I thought about resizing easily available ones. Now I will!
This is exactly what I needed to see. Thanks! I don't have a table saw, so mine will be a manual cut. Just seeing the adaptation of size and finishing off the end with tape was helpful.
Nice result on that cut, no tear out at all.👍 Way better then what i would expect from a crosscut. 😀
I can't believe how well that worked.
John... you are sooooo frickin smart! You make feel like a beginner all over again!
I used my miter saw. I can never find the 12x12 at my local store but they do have a 24x12 at the same price. I cut it in half and get two filters for one. I don't worry about cutting both sides at once. It didn't seem to be an issue with the ones I have cut. Good video John!
Nice 👍 😮
Most filter distributors who make filters to special sizes use a similar saw but with a stone wheel blade. This cuts all the materials nicely in a single pass and then they finish the cut edge with a cardboard end cap using hot melt glue. I will list a source for the end caps in another post.
Great , I just threw out a filter that I bought too big months ago. Totally would have tried this!
Thank you I needed to see that I just got a whole bunch of filters from Walmart so I told him what size do I needed but they still send out the wrong side
Much better than the chainsaw method.
You're a god
Thanks man
Speaking of table saws; are we going to see you build the new one soon? I'm really looking forward to that build!
I always do my filters on the table saw. 😁 it's an amazing tool. I love yours! If I didn't have one that I love, I'd build yours! It genius!
You are cracking me up 0:06, and 0:10... always fun on this channel.
I'm more interested in what you want that size for.... Hmmm. Good idea cutting half at a time!
I'm with Art, I'm curious as to what is in progress.
Isn't it for his shop air cleaner ?
Now this is the content I want crazy and wacky ideas
Daredevil!
I’m surprised he cut that good, I would be scared to try that, I think I will stick to the bandsaw, nice video.
my dad used to do this for his paint booth filters. He would just sandwich them between two pieces of cardboard and cut the whole thing in one pass. Never an issue.
I was afraid that steel would wrap up in the blade Glad to see it worked 1/2 x 12 probably did it
Personally, I thought your speculation regarding the danger associated with the full cut was insightful. Your solution was brilliant, and effective.
I've cut down piles of cardboard before with a circular saw. It works *really well*.
Thanks for sharing !
Thanks for the video.
How was this not on the Red Green show?
I loved your smiles :-)
One can cut 6 cabin filters for the car from just one furnace filter in this way. Imagine savings.
I always wondered why you changed your table saw ? congrats on your filter
Is that the new one he built? I seem to have missed the conclusion somehow, need to go back and find/watch the end of the series.
@@super_slo This is his 'new temporary' saw before he makes the new saw.
nice out of the box thinking :-)
Perfect! 😄
I was certain that there would be kickback! He didn't even use a sled, and you never know what that crazy grain pattern of a pleated filter will do!
Good thinkin' John. JimE
I modified the furnace to accept standard sizes, do the work once.
nice
Just wondering, do you need a dust mask when cutting a dust filter seems redundant.
I love your videos John, but I'm only here for the comments on this one, lol.
Duct tape and a table saw, that’s all you need to create stuff!
I guess I won't need this extra pair of nail clippers after all :(
I never resize filters any other way!
Making a small dust collector / air cleaner?
Faced with any problem I now ask myself "What would John do?"
My tin snips are going to get a lot more down time.
Yikes. I’d be pushing with sticks behind a blast shield on the first go.
Speaking of filters, have you come up with any solutions for the dust control issue with miter saws? Like everyone, even when I use a shop vac with my saw the dust still goes everywhere! Have a good week John!
ruclips.net/video/g3JU2_iGYxo/видео.html He discusses dust collection while building his miter saw station. Some people will custom fit a hood around their saw, may catch a little more.
Saw hood to passively contain the dust. Then work on suction here and there to get most of it seems to be the best general direction to go in.
2HP saw with 5HP dust collector!
AHHH, the ol' standard to metric conversion fitment issue.
I used to buy hot-dogs at a stand across the street from Clint Eastwood's high school. (before he became famous.)
hope to hell you didn't put ketchup on those dogs.
You should have wrapped the cut end with bacon. Amazing results will result.
Hi John,
Perhaps you could run it through the saw backwards, have the teeth nibble on the mesh.
Greetings from Greece
Or put the blade on backwards.
@@JDeWittDIY That seems better. You won't need to fight the blade.
dull blade snag wire, like a shotgun a finger gets caught up pulled into blade.. new nickname around the shop.. ect
The HVAC installer didn't make the filter slot on my furnace to match any commercially available filters. I'm stuck using those cut-to-size fiber filters.
The green fiber filters basically just keep some hair and large debris from going into the furnace. I'm looking into a similar solution.
When are you going to start your table saw build? You would have better off to keep your old saw.
The Enforcer!
0:07 Troll face engaged!
On a serious note, maybe you could also snip all the metal meshes first, then cut it on the table saw in one go?
Dirty Harry strikes again!
