was just cutting out wood for my new box and the design included a lot of kerfed boards so i thought i'd just quickly show you how to do it. this was really spur of the moment so sorry it's a bit rough.
hi how do you bring back the swolen wood? I have a piano and one of the leg is swolen due to heavy moisture. Would it be working to soak it on the hot water and then clamped to its shape for some time?
I'm attempting 1/2" mdf for a round speaker enclosure. 3" full range surround speakers. I started with 1/4 inch deep, and would not bend. I cut deeper then it breaks. Any ideas?
i know this is late which i apologize just got back into the country haha but it does compromise the integrity of the board as you are removing 90% of the material for every cut you make. so if you're worried about it breaking i would fiberglass the back side of it. that it what i did for every Kerf i did for this box i was working on and it's super strong now.
first off, multiple extremely clever techniques I took away from this video so THANKS FOR SHARING! My question: Why plywood? was it a cost or availability based decision or is there a characteristic which makes it better suited for this project? I was thinking two nice contrasting hardwoods...my go-tos are always Maple & Walnut... wood (shameless n corny pun, lol, but I couldn't help myself:) look awesome for these stools. Thoughts?
it's not plywood actually! it's 3/4" MDF. it's what is used a lot for making subwoofer boxes which is what i've been doing a lot lately. and thanks for the comment! incase you wonder MDF is pretty dense for the cost and it is is easy to work with for audio stuff.
ArcanePath360 yes that's correct. I've used fiberglass to make the bend strong and it's worked out great. Well usually I use wood glue in each of the cuts and then fiberglass on the inside of the bend. Its worked great
Thanks. I've never used fiberglass. I thought about using bendable ply with wood glue, but I might as well just glue two bits of bendable ply together to get the same end result.
if you're wanting to do a 90 degree bend then make 12 kerfs or cuts that don't go all the way through. if you want 180 then make 24. it takes out the material so the board can bend. make one line where you want the bend to start and one where you want it to end and then spread other 10 or 22 cuts between those two evenly. does that help at all?
Mohammad Omidi try it on a scrap piece. see if it'll bend without cracking. if it does crack go deeper. if it's too fragile then go shallower. just try it out on a scrap piece first to play with the depth.
This is not the proper way. the slot you do should be in "V" shape, so that there should be no gap between the bend. and it also makes the finished product stronger.
I hate it when people always say” but yeah” “so yeah” in the middle of a sentence.. because it’s meaningless in structure of a sentence and pointless in verbal communications.
Never do 12 lines in a 90 digress bend in Kerf because it used in making coffins 12 meant 12 apostles and one was judases so make 14 considered bad luck in kerfing
