Main Discussion Area > Horn Bows
First attempt build a long !
Bjoern Sofeit:
You can use dry heat - korean bowyers do it - but cooking them will ensure that you don't go over 100°C. Cooking them for max 10mins and then clamping them for an hour or so is enough. The 17" horns should be good for a hungarian bow, the other ones are comfortably fine for a turkish bow.
Stick Bender:
Thanks Bjoern the type of bow that I'm attempting is like Eds latest composite prodigy thread , maybe I will steam cook them and straiten I have seen so many articles on bending horn from bolling to dry heat to open flame I think Adam Korpowicz preferred bolling ,at this point I don't need them perfectly strait but strait enough to hide glue to a board , I'm going to continue with this set to iron out every thing and if I don't have enough length I will work the others or adjust the design !
mikekeswick:
Steam is the way to go if you aren't sure.
Stick Bender:
Thanks Ed I got your spec sheet in the mail tonight really more of detailed journal of your work you keep meteculious records there Bud I appreciate it hope to get some work in on it when back from hunting Saturday unless I poke one , thanks Mike maybe I will try steam for the initial bending with them being thick at this point might be the better option !
Stick Bender:
I made up some simple tooling for straitening & prepping the horn strips dug a 4 x 4 out of the wood pile & milled it dead flat added a quick release clamp ,made some assorted shims and used dry heat with a infrared thermometer & didn't let the heat get above 220 Deg F, put shims at the areas that needed straitening it worked great I also found some dead flat Ply wood and made feed tables for the drum sander I decided to use the method I have used for years making furniture Lams I used commercial grade fiber glass reinforced carpet tape to bond the horn to the feed tables it is a very strong bond it will need heat to release them next I will start taking them down in thickness with 80 grit sand paper on the drum !
