Heat bending
« on: January 17, 2015, 11:02:00 pm »
Will a small ceramic 1500watt heater get my wood hot enough to bend it.  The lams are about 3/16" thick..?

So I did a trial run it worked sort of I guess,  how long do you apply the heat before bending .....?  I did it for a couple minutes.. ???

I would think that a small heater(is it radiant or fan forced) would take longer that a couple of minutes. I has to get hot enough so you can't hold your fingers on it for more than a couple of seconds. For bending and untwisting you don't have to have the wood turning brown but it does have to be hot and deeply hot. So move the heater away a bit to let the heat soak in.

I set it up with the bow clamped down so that the tip will go down get the heater close and put a c clamp on the limb and weight on the clamp on the side that I want it to move tot then just check on it periodically till it moves the amount I want and turn the heat off and leave it to cool, it will take more than a couple mins, I can do a mock setup tomorrow and take pics if that will help

I use a $20 Wagner you cheap skates, that goes double for you bubbly! It'll only get you through about 75-100 bows before you'll need a new one.

I have a 10 dollar piece of crap heat gun too. It gets the job done.

Now don't be the bad chris, i use my wagner heatgun all the time, but i use the floor heater on things that need to heat a long time to get deep so i can do something else while it heats up, i got it why not use it, plus i read where john strunk has used a floor heater on occasion to heat a bow

I've kind of had it in the back of my mind that radiant heat would stop the back of the bow from getting scorched. But with all the excess time it takes you could make a narrower caul. I also use a 420 Wagner. You can reheat coffee with them too.

I recently broke the fan in my mastercraft plastic heat gun. I dropped it many times.  I had my shopvac blowing the heat (through the ceramic element) on the stave, but it was a two-handed operation.

I will probably pick up the wagner ht775.

I can see how a long soak on top of a floor heater would prime the wood nicely. I would think a heat gun is required to do real tough bends.  I hope this camping season to try some campfire tempering....

John strunk used a little space heater, but I think he was just using it to cook in a steam bend and dry it out a bit. He also recurved a yew bow after steaming the tip for all of 5 minutes. My mind was blown
