Technical Old school louvre punching by hand.

A mate of mine just sent me a link to a video he's put up on youtube.

He made male and female dies but this method of hand punching is one I have not seen before. The car may be off topic for this group but this is about the method of punching the louvres. No flaming of the car (for being non hamb friendly) please, it's my friends project.

Mart.

 

Seems to work rather well.

 

That's cool. I like the way he uses the flat part as a guide for the one piece while also holding the lower die in place.

 

Louver punching by hand was way before my time.

 

Very clever. I’ve done a few louvers in 16ga by cutting a slot first, but the guide on the recess is damned clever.

 

I like every bit of it except the CLAW HAMMER . Damn it , that is for driving nails , not working on a car .

 

So box nails are the ones with a steering wheels on the non pointed end?

 

That is pretty slick!

 

Now if I could just get my deck lid on the table of a laser cutter to make the slots Might be scary me cutting the slots with a cut off wheel. I dig the idea!

 

Wow the sheet metal bent quite easily.

 

I just thought the method was pretty clever.

 

That’s cool and love the old school ways and thinking outside the box

 

That I have to try, thanks for the video.

 

Came out well I think

Well thought out, thanks for sharing, Mart!

 

I don't know...... Look how much wood and nails are in the old Ford's and chevys !!

 

It was Trevor, two posts up that made the tool and the video.

Nice work, Trev.

 

This fits right into my “Blacksmith” way of doing things!

 

Pretty doggone clever if you ask me. Or even if you didn't ask...

 

That’s a really nice way of doing it especially for the domed louvres really nice work

I’ve done my own by hand but didn’t make any special tools as this guy has. I made a buck in some hardwood and used a wooden bolster

These are mine

 

This is the tool

Not my invention I found a photo on the net and made the tool up

I wanted the round louvers as i think they look more like an old school rod ...

Clever, I like it

 

I would have loved to make tooling like this but I don’t have the necessary tools to make anything like this. Awesome work though . The only piece of advice I can offer anyone doing louvres is to prep the metal as if it were for paint and remove all burs from cutting the slots before you punch the louvres it saves a lot of time and sore fingers afterwards

Your not wrong mate got to take all the paint off and after the cut sand off the burr

I did miss a little of the paint and decided to send the panel in for blasting so it's nice for primer

This is more or less how my grandfather cut louvers. He used a wood buck and a modified brick chisel that made a rounded shape. I can't remember how he cut the slots, but I assume it was with a grinder. I was very small the last time I saw him do it.

We got to use the louver press at the chop class I took last fall... it was much, much simpler.

 

Thanks for this additional photo. It cleared up a question about what the "female" die looked like, since I didn't see a very clear image of it in the video. I wondered if it was profiled to match the male die that's hammered in, but it appears it's a wide "U" shaped die that has a simple straight-cut edge rather than being a profiled mate to the male die.

Thanks.
