Bending HHB
« on: December 07, 2016, 07:32:04 am »
I see all the nice hooks and flipped tips on so many bows posted here but I just seem to have a hard time  getting very much bend out of my HHB. So far I have only used dry heat wondering if steam would be better. Just hoping some of you guys that use HHB might be able to give me a few tips or is this the nature of the beast. Thanks

Use steam if your trying to put hooks in, BJ. If you have time, Id just grab some scrap pieces and practice a few bends. Get a feel for how long to steam and such. Dry heat should do anything else you want done to HHB. If your struggling you probably aren't heating it enough.

Thanks Pearl it's the hooks I'm struggling with. I can get the smaller bend no problem but haven't had very good consistent results with dry heat for the sharp bends

Thanks Upstate, look like I'm going to have to put a pot on the burner and do some experiments

Jackson here's a quick update. I did a little experiment last night. The steam worked much better but I can see now that I need to modify my caul. When I get a chance I'm going to make some changes and try it again. So far it looks much more promising.

HHB can be tricky to bend even with steam.  Even with careful preparation and long steam time I have had recurves splinter.  I prep the tips by shaping them into a shallow D section, on the belly side of course, following 1 growth ring and sanding the edges.  I also always use a band with HHB.  A splintered recurve can be fixed with an overlay but it is such a pain in the A$$

Thanks Marc, I haven't done a real lot of sharp bending yet but the little I've done seems kinda unpredictable. I might get a nice bend on one tip then flip the bow over and the other end just doesn't seem to want to move. I do realize I need to rig up a better caul system and band. For a band I'm wondering if I went with something with a little spring to it. I use to have some 1/8" spring steel that would probably be good.

Jackson I took Marc's advice and went with more of a D profile on the tips, steamed them at a good boil for 1 hour.  I had my caul and clamps all ready. I had a pair of leather gloves put bow on caul and lined it up good then kinda slowly let it bend into shape. I could feel it giving in not sure if I could have just quickly bent it but I'm very happy how it worked. I also toasted the belly so far I really like how this stave is coming along other than the handle area. I might have to rasp it down and glue something else onto it. Good Luck with your HHB I really like it for a bow wood but I never had the chance to get hooked on the yellow stuff yet.
