First time kerfing

[CleanSierra]

This is my first time doing any kerf work. It always seemed like a pain in the ass, but it wasn't bad at all. I made a T-line jig for the cuts and adjusted depth on my circular saw. I only used like 11 evenly spaced cuts. I think in the future I will increase that by a couple to make a smoother curve. I should have taken pictures throughout but I did not. I only have a couple of the painted product, and it's just a test piece. I have no enclosure that needs to be built currently

looks pretty dang smooth to me! lol

thinking about trying kerfing again for my next box. any suggestions?

great job for your first time, just dont forget to reinforce the inside of the kerf (if you have not already).

Your boxes come out very nice I think. You've done kerfing before, right? How do you do it now, and we can compare

No worries. This was purely a test piece. I didn't waste glue on it even. I did bodyfill the back(inside) side, but didn't sand it. I wanted to see how I did with the cosmetic side first.

I plan on doing a little gauge cluster with my OM-1s under my dash as a sort of center console tucked up and away. I figured I'll kerf it just a little, not a 90°, probably more like 60° so it's angled up at me. I wanted to try my hand and I REALLY like the way kerfing looks, I always have.

Side note: Your box builds are on another level and I hope to get there soon

typically, I will mix up some resin with a bunch of saw dust from my dust collector, making it a thick paste kinda like peanut butter but no where near as thick. I fill in the voids (cuts made from kerfing) with that, once cured, I go back over the entire kerf bend overlapping onto some of the wood that was not kerfed, apply normal resin, followed by fiberglass mat, resin again, and another layer of mat, followed by resin. larger kerfs i will do a couple more layers.

haha thanks, my boxes are nothing special tho, just time and attention to detail anyone can do it
now having them sound good takes a tad bit of extra work. lol

thanks man! and yeah i did one box with a lot of big kerfs for my first try lol

and how i did it;

made the cuts with a radial arm saw (sooo much easier then a skill saw)

filled the gaps with wood glue.

screwed them in place.

once dried, fiberglass mat and resign inside of the kerf.

once that is dried i sanded and then did body filler and then sanded that.

and this is how it came out.

just looking for more pointers cause i might be doing the same sort of design but for my x15 and not a small little 8" lol

So resin with dust-Cure time------>resin,mat,resin,mat resin correct? I'm taking notes because this is good stuff. How many cuts do you do for the bend? Or do you base that in the radius size?

And obviously body fill after the last layer of resin and mat cure.
