Zelph,
One respectful mod of this screen will have diagonal ridges running from the bottom left corner of the flashing to the top right of the flashing sheet. I plan to do that in horizontal rows every 1 1/4 inch.

Is there a hand tool to roll the ridges into the flashing? Possibly something like a 1" OD by 1/8" or 3/16th width rubber wheel on a 6" handle?

Thanks
Paul French

You might be able to create such a device by taking the large diameter wheel off of a pizza cutter and replace with different size wheel to meet your needs.

I love it. You are so good at thinking outside of the stove, I mean box.

Re: Whirlwind Windscreen, Tools to make by hand

Zelph or anyone,

I am going to try to incorporate Zelph's whirlwind air inlet design (Thread name: Whirlwind Windscreen) into a windscreen I am building out of the .004 stainless shim stock. I don't want to make a mess of it and only have hand tools and one of those electric hobby tools that takes all kinds of bits (name escapes me).

How can I cut the rectangular air inlet holes with an uncut side for the whirlwind flap without all kinds of remaining metal splinters ?
What tool works best to do this on .004 stainless shim stock?
Also, how do I eliminate the sharp edges all around the outside of the shim stock?

Regards everyone,
Paul

Use a Dremel Rotory Tool with Diamond impregnated cut-off discs. Harbor Freight Tools has them. Practice on scrap metal first...wear safety glasses ;)

Stainless shim stock comes with edges that are smooth. Use fine emery cloth to sand of edges that you cut. Wet&dry sandpaper at auto parts stores sell it.

Good luck on your projects :D

Dan,
I did win and receive the leather punch set you suggested I get for prototype hole punching.
On this Whirlwind Windscreen can you suggest how I punch the holes? What type of tool would I use?
I can't see the picture well enough to determine the shape of the air inlet holes you made, but I would guess rectangular.
Regards,
OCD Paul

Rectangular holes will be made with the Dremel tool and diamond cutoff wheels. Cut the 2 short ends of the rectangle and then the long side or visa versa.

The round hole punches were from a different thread :?

Dan
Thanks for the explanation. Now if only can remember where in the world I put the dremel.

How do I determine the amount and size of the inlet air holes to be dremeled into the windscreen?
Apparently I also need to have the air inlet holes at approximately the same height as the top of the Starlyte or is there a measurement that needs to be made to determine the optimum height?

Thanks for all of your patience and your great assistance. assistance.

Trial and error is how we determine how many. If you have a large stove more/larger holes will be needed.

Vertical louvers will make the incoming air swirl as long as the flow is sufficient..

A minimum height for the windscreen is to be 6" to get the swirl effect.

Keep the louver 1" from the bottom of windscreen. Make them 1.5" tall. Try 4 of them to begin with.

Your Dremel is in the utility closet next to the tray of hand tools. :mrgreen:
