Introduction

I have had many request to show on net my method for making, siding and roofing. This page is an attempt to fill those request.

The jig is so simple to make, I couldn't see why someone hasn't made one before this and put it on the market. I spoke to Lewis Polk at the ECLSTS about the jigs. We discussed why someone hadn't put one on the market. We both agreed that it would not pay for itself, and you would never recover your cost.

"Cutting the Basic Boards."

The jigs are made of 3/4" Poplar. I wanted to use a hard wood and chose Poplar over Oak, because it has a much finer grain. I cut two boards to size 6" X 9". I'm making four types of jigs at this time. One board can be used for two jig's, one on each surface. In my example I'm only showing how to cut two jigs, you can make any style you want just by changing spacing of the slot's. The slot's in the wood were cut on a table saw using a carbide saw blade, with a tooth width of 1/8". The slot's were cut approximately 3/32" or 1/8" deep, depending on the jig use. Experiment making different styles of jigs, and see what you come up with. The dimensions for cutting the grooves in the jig.

"Tools."

002 A few basic tools are needed to make your roofing and siding. A square, a ruler and a straight edge for laying out, metal shears and scissors for cutting the metal, a small hammer and spline tool for creating the grooves in the metal.



001 For those of you who do not recognize the tool in the picture on the left, it is a spline tool used when replacing window screening. It can be bought at most stores that sell building supplies. It has a wheel on each end, I use the wheel with the round edge when using the jig. I remove the concave wheel, as I haven't found a use for it yet, and just gets in my way. For those who don't have a spline tool, you may use a wood stick, 3/4" X 6" x 1/8" in size for *burnishing the metal in the slot's of the jig.


*( Burnishing = Rubbing the metal into the slot in the jig.)

"Sources of Metal for Your Project's"


028 A source of metal suitable for use in the jig's, has always been a problem. Most metal is not soft enough to use in the jig's. Aluminum flashing is the right gauge of metal, but to hard. Other metal's I have tried were all to hard for my use, unless first heated to remove their hardness.


What I finally used were, Reynolds steam table pans. The metal is soft enough to work in the jig, but is still ridged enough for some support. I bought the pans I use at a Local Sam's Outlet Store. There were ten pans per package, for around $10.00 Dollar's. The pans needed no tempering, and gave me large piece's of metal to work with. One pan will yield, 1 - 15" X 16" and 2 - 4" X 7" pieces of metal. After cutting the steam pans and flattening them a little, there are still a lot of bumps and dimples in the metal. Don't let it worry you, as you work the metal the bumps and dimples go away.


The steam pans are fine for use in the jig. I was disappointed that the metal was too hard for making corrugated metal siding with the Fiskar paper crimping tool. The Fiskars paper crimper can be found in most of the crafts department of stores.


I used the disposable candy and small cookie trays for making the corrugated siding, they are thinner and softer metal and crimp well in the Fiskars paper crimper. That beat's cutting and cleaning beer cans, and they do not have to be re-tempered to use.

"Using the Jig for Siding or Roofing."

003 004
Align the metal with the top and side of the jig. I also draw pencil lines across the board to use as a reference point.


005 006

When starting the first ridge in your roofing, leave at least 1/2" of extra metal. Using the stick to start, apply enough pressure to indent the metal, and get an idea of where the slot is under the metal and act as a guide for the spline tool. Use the stick or spline tool to push the metal to the bottom of the slot. Run the tool back and forth to make an even impression in the metal.

008 009

After you work the metal into the slot, the right edge will be straight up. Leaving the metal in the slot, use the end of the stick to flatten the metal back onto the board.

010 011 012

Turn the sheet of metal around, and place the ridge you made in the metal into the first slot on the left. Holding the metal tight against the board, use your stick to mark the metal as before. Then rub it into the slot with a stick or the spline tool. The edge of the metal will bend upward. While holding the metal tightly in place, use the stick to flatten the metal against the board as before. Repeat the process over to make 2 or 3 ridges.
Remember to keep the finished work to the left. The un-worked metal to the right. The reason for keeping the un-worked metal to the right. When you push the metal into the slot the un-worked metal will move to the left, because you are holding the finished ridges in the slot's as a guide for the next ridge's location.

014 015

Even though you flatten the work piece back onto the board, it still will curl up a little as in the picture above, on the left. To flatten the work piece, lay it on a flat surface finished side up and using the end of the stick, rub between and next to the ridges. This will sharpen the profile of the ridges and take the curl out of the metal.

As you work with this type jig and learn how to use it. All kinds of projects will come to mind for the use of the jig.

" Time to work on some finishing touches."


"The roof edge."


Let's take a look at finishing the edge of the roof.


Make your metal roofing first to the width you want, then cut the Foam Board, wood or what ever your going to use to fit the metal roofing. My reason for this is, the roofing doesn't always come out in even inches, and I want to have a ridge on the roof ends, to turn under.
In the top left picture remember how the edge of the metal turned up? This will work to our advantage.
When starting the first ridge in the roofing, at least 1/2" of extra metal was used. This will be used to make the finished edge of the roof. Since the first ridge was flattened, we will now put it back on the board, the ridge is pushed into the slot to make it return to the straight up position, so we can use it to turn under to make a finished edge. Use duck bill or needle nose pliers to bend the metal to fit's your roofing material.

"Let's cap off the roof."


Cut a strip of metal about 1-1/2" wide and at least 3" longer than the peak (top) of the roof. Lay the piece you cut on the board, centering it on a slot. Push it into the slot, allowing both edges to come up. Then bend it to the shape of the peak of the roof.

For the next step it is best to glue the cap to the roof, letting the extra stick over the ends of the roof by a couple of inches. Using scissors or metal shears, cut the cap piece down the center to the peak of roof. This give's you two strip's of metal. Making sharp bends. Bend the two strip's so they cross. Now cut the bent pieces straight across to finish the end and glue the pieces together to finish.
