Title: Riser OOPS
Post by: hartj57 on January 09, 2015, 09:30:09 pm
I've been working on my first bow for a while now. It is made of Red Oak.  Today I cut the shape of the handle out.  However, I inadvertently cut in too far and made it much narrower than I had intended. (http://i.imgur.com/E5F69Mc.jpg)
The intent is to make the bow finish at around 45 pounds.  I still have a decent amount of thickness in the riser.

Does this still look viable?  If not, should I add another strip of wood to the back of the riser to reinforce it?  What are my options here?

P.S. Yes, I know the fades are quite uneven. Is that a huge problem?

Signed,

An aspiring young bowyer.

Are you planning on blending the riser out into the fades a little more?

Do blend the riser in smoother to the limb

Your handle isn't too narrow. 3/4 inch wide is fine.
What i'd be worried about is the bad glueline at the fade. Next to your watch in the photo with your hand.

Chances are good that riser will pop off the way it is, and with a bad glueline(especially if a titebond type glue was used).

Is there anything I can do to fix my glue line on the riser?
Also, are the fades supposed to bend when you tiller the bow, or should the bend end at the fades?
Sorry for the super simple questions.  I am very new to bow making and woodworking in general.

if the riser pops off, ,re glue with epoxy(or if it starts to lift there)
I like to make my board bows with no glue on handle,, so nothing to pop off( I like to eliminate as many variables as possible to insure success)
you will make more mistakes as you go,, all the best bow makers here have made lots of mistakes and try not to repeat them,, lots of great advice here,, just continue with what you have,,  :)

the cut the fades more like this. then tiller to keep this part rigid. the bend should begin in the part of the bow that has no glued on riser. if you let the glued on part bend it will almost surely pop off.

And I've found that french curve is good tool for getting that curved fade profile per Aaron's line.  I print french curves from online sites & then glue to flexy cardboard.

Awesome.  Thanks for the link, osage outlaw.  It has a lot of good info!

thanks so much! I've been wondering about that!  I'll also try the french curve idea Knoll posted.

I don't know what I would have done without this community (actually, I do; I would have broken my bow).  You guys rock!

Practice drawing the curve on paper a few times. It's really not that hard to just sketch onto the bow with a pencil, when you know what it should look like. If it doesn't look right, just scrape it off and try again.

I use a frence curve on mine, but I went the whole nine yards and bought the set for $8

The glueline is the important part to try and fix BEFORE it becomes a problem. The fades also need work but i'd do that after the glueline.
Your best bet at this point is to heat some epoxy gently so it becomes runny. Then try and get it to flow into the gap you have. Flexing the bow with the handle held in a vice will help to suck it in. I would make a few blocks of wood up to fix the riser shape and then use those and a piece of leather or similar to protect the back and then clamp it up nice and tight. Inner tubes or clamps will work.

You can also use the bottom of a paint can to trace out your fades. Just play with it till it looks good.
