I Forge Iron

G'Day
I would like some some help on different techniques to band wooden blocks together using steel straps, without burning the wood. I tried searching the site but to no avail.
Cheers mark

One thing to remember is that if you are charring the wood your bands are TOO HOT. Shrinking is not done at a red heat but more like 400 to 500 degF Usual way of checking is when a wood sliver starts feeling like the iron is slick when you push it against the metal.

I agree you may be too hot
When putting an iron tire on a wooden wheel you need to start with a close fit, heat the steel evenly slide it over the wood then put water on the steel to shrink. On a wheel you should hear the wood starting to creek under the pressure of the shrinking iron, if not it probably is too loose

This is easy, all I used to do when I was an apprentice was make the band about 1/4" smaller in circumference than the block, get the band to a "greasy stick" heat then push the sucker onto the block with a 1 ton Massey hammer, oh you may not have access to a 1 ton hammer. That may make a difference, sorry.
