*TECH* cheap aircleaners for carb stacks..pics

I figured some of you guy's may be able to use this if your running carb stacks without air cleaners.

On my '33 i'm running 3 rochesters. I made some stacks out of stainless pipe, and welded a piece of flat stock, tapped with a 1/4-20 hole, at the base to thread on the carb stud.
This worked great for holding the stacks, but i had no air cleaners..

I went to the local hardware store and bought some metal screen door screen in a roll.
I set the stack on the screen to get an idea of the the size piece i needed, then cut it out around an inch larger than the inside dia. of the stack.

I then started to form the screen in a cup shape in order to slid it down the stack.
Once i had if formed, and it fit tight, i glued it in place. I used window urathane to glue it in. ONLY put the glue on the top side of the screen!!
This way, if your sloppy and some happens to come off later, the screen will catch it and you can dump it out when you clean the filter next time.

Now you have a stack with a screen in it to keep the bigger stuff out...now on to the filter itself.

I went back to the store i got the screen at. They also sell lawn mower's, and parts.
I bought 3 Briggs and Stratton foam filters.

All i did with them was cut them to the size of the hole as well, then slid them down to the screen.

I now have air filters that will deffinatly work better than nothing, even if there not K&N's !!

Total cost was about 18 bux..

It's a simple idea, but i feel it's pretty effective.

Because star photo is too slow to upload stuff, i'm gonna host the pics on here.
Following are shots of what i just talked about, and the finished product..

Hope some of you can use the idea

Here's the roll i bought.

 

Here's one shot of the screen formed into the cup.

 

Another of the cup, kind of a side shot so you can better see the amount i used on the sides.

 

Here's a top shot once the screen was glued in.

 

Here's the Briggs filter cut to size..

Here's the last shot. Bottom of the stack, with the foam installed.

that's really cool...what about a backfire through the carb...how flamable is that stuff?...i'd hate to have it melt and drip into the carb

 

I've backfired a couple times, and it's blown the foam out.
The foam is air filter material, so i didn't worry about it.
It's the same type stuff Edelbrock uses in there triangle filters.
Although, thats a good point.
I wouldn't use any kind of filter material..stick with real filter stuff.

 

it's funny that this was posted today...just had a conversation about this yesterday

 

Tony that rules! thanks for the tech... that would work good for more than just a car application-

I'm gonna make some screens for my scoops...

If you are using foam, you may want to use perforated or expanded metal instead of screen, to reduce the chance of ****ing pieces of wire into your motor.

Instead of glue Id suggest soldering in the filter, just tack it at 4-5 places.

You can solder to stainless with a liquid flux available at well equipped hardware stores or you can dilute Muriatic acid about a 1:1 ratio.

If using expanded metal and soldering be sure it is not aluminum, it doesnt like acid.

 

The plates i made to hold the stacks on the carbs are 3/4 wide, making a pretty good base for the screen.
Between that and making sure that the screen 'ends' are facing up and being coated with urathane, i wouldn't think any of the strands of wire would come loose.
I havn't had any probs yet.
but you do have a point worth making for sure.

Soldering is a good idea as well.
