Home Forums Hunting & Shooting Bowhunting How to build a laminated bow

I placed the thick end of one piece next to the thin end of another so you can see the taper.



Each limb will get three of these tapers and one strip of parallel thickness Hard rock Maple that is from the piece of wood my Father cut so many years ago. This is the same piece of wood that I used in the riser.

On the front and back of each limb will be a thin layer of Kingwood and then clear fiberglass. All of this will be assembled with the same epoxy I used to make the riser but first I need to assemble an oven box.

I built the oven box for the bow form. I will spare you the details since it's just a box made from scrap plywood that was left over from another project. I will say that It is 12 inches high and 22 inches wide and 74 inches long. By removing 6 screws at each end of the box, I can reduce the box to four individual panels for easy storage.

You will also notice that the box has neither a top or bottom. The reason for not having a bottom is so that I can bring the box to the form that will be covered in oozing epoxy and many clamps (creating a challenge to move) I would rather bring the box to the form.




With the box complete, I assembled the heat source that I will use to raise the inside temp of the box to 160F. A trip to the Home Depot for the supplies ran me about $30.




The first step was to get rid of those pesky warning labels. Nobody reads them any way. The extension cord company knows I am not going to read the label in English so why would they expect me to read it in Spanish? I hope the extension cord labels are not like mattress labels. I would have to spend time behind bars for removing them.




Once I cut the extension cord into bits, I wired the light bulb bases together in series so that one plug would power them all.




A quick test revealed that I had had paid attention in shop class.




I placed the form between the two light bulb boards and brought the box to the form. My Son will need to help with this part as the box is a bit long to handle alone. Everything fits nicely.

The cover of the box will be an old closet door from our last house. It is hollow so it is light enough to move around and it was free.

I drilled a hole in the door and inserted the probe of a thermometer. This way, I can keep tabs on the temp inside the box without opening it and letting the heat escape. My wife won't be cooking a turkey for a few months anyway.

After two hours with the bulbs on, the temp never got above 135F. I will replace the 100 watt bulbs with 150 watt bulbs and add two additional bulbs to the boards

The next test will include covering the oven box with a canvas to trap the heat better. I think 2 extra bulbs should do the trick.

The next step will be to make a test bow out of scrap material so I get the feel for the assembly process and so that I can check the glued up trial piece for any warps that I will be able to correct before wrecking a bunch of expensive woods and fiberglass. It is a piece of mind exercise.
