Technical Tech Week - Hand-Punched Louvers with a Stone Chisel

Seems like drilling the holes using maybe 1/8 " on each end would give you a spot to watch for as your cutting with the disc and finish off the end cuts as well as a stop hole to prevent any cracking that might want to migrate out from the ends. By the way, excellent Tech week stuff.

 

SWEET nice tech

 

Couldn't have said it better myself. That's why hand painted lettering looks so much better than vinyl.

Perfection is vastly overrated.

 

Very awesome Brent! (And I love the signage on the tool box!)

 

Thanks, man! My shop has been getting all sorts of stuff like that since real signs are $$$.

Thanks!

Thanks s is pretty much EXACTLY why I chose this route.

Agreed. This is something mentioned abov, as well. And 1/8" is probably the thickness of most cutting wheels, too, so it would disappear in the cut.

 

Drilling 1/8" holes could also allow you to position a jig for the next set of holes or for a guide for the cut. Having only one working eye makes all of the critical alignments and exact tool placement very difficult any thing to help.
This is a great thread.

 

Cool

 

Freaking totally awesome!! I foresee a tool in my box getting a totally new function!! Bravo!

 

The article I posted has a jig, of sorts, using nails as guides. The fellas I've spoken to (or read about) who've used the jig abandon it after a while due to it being cumbersome. I do believe that after doing 30 or 40 of them, now, they're much more consistent. As well, I have a better feel for it. With a mark on the tool and workpiece, I haven't had issues nor wants for a guide or jig. If you take a look at Andy Kohler's pics you can see his are pretty darn consistent, too, and he free-hands them, too.

I'm not saying that having a guide should be avoided, I believe it's whatever works best.

After a bunch of practice, I can see this an easy tool to fab for any level of skill and the learning curve is pretty short.

Thanks, fellas. I do appreciate it.

 

I just looked at my votes and I'm at twenty! Not too shabby! Thanks to the 19 folks that dug this thread enough to vote for it.

I'd love for folks to post up there hand-punched louvers in this thread, in the future.

 

I will be posting mine in the future I looked and chisels this week and I couldn't find the right size I also want to order and panel bag, This is definitely something I am going to use Thank you for the tech! Jim

 

All well done! I did a thread on allmetalshaping some time ago for a contest

A little different aproach

 

Rad tech, @BRENT...I was shying away from louvers, but this brings me back full-bore. Have you tried it on aluminum?

 

Thanks, man!

No, I haven't, not yet - only because I don't have aluminum sheet metal in my scrap bin.

 

Sick! Thanks for posting this! Really like the potential this brings.

 

cool tech. i wonder if a piece of thin masonite, peg board could be used as a fixture? every other hole, wide, every 3rd hole, over.

Short time to vote

 

Shameless Bump for more votes....... Jim

 

Thanks for sharing .

 

Great tech.. Very cool...

 

Thanks for sharing its simple and its a great ideal

 

I was going to post a picture of a doghouse I built for a pumpjack engine .I had cut slots with a diegrinder cut off wheel and then rounded the end of a big chisel . I lined the slot up with the jaws of my vice then whacked the chisel until the lover was opened up. I guess the photo has been deleted from my files . Yours look a whole lot better then the ones I made , but then again the cows didn't care they just wanted water.

 

tooooooo cooool got my vote

 

Wow ! who knew ? I have A 23 t turtle deck lid that is wavy .....Why not try ?
Cool stuff !

 

I wanted to publicly thank the folks that donated to the prizes for tech week. In particular, those that supported 4th place: @GOATROPER02, @270dodge @Tman, @aonemarine, @ems customer service, @117harv, and @typo41.

Thanks a bunch, fellas! I really appreciate it.

 

aww shucks..... Dont get bit LOL

 

Hey Brent here is my first attempt at hand punched louvers I will make some changes as I go to my process I need to use a smaller drill bit for the ends and work on straight cuts/ layout but this is awesome I am really looking forward to using this on my build! Thank you for the tech Jim

 

Nice!

 

Thanks Brent I am excited to continue learning this process! Jim
