I'm tired of waiting for my stuff to show up...virus!
I want to build a bow on my bench without a form.
How do I start? Numbers?
Let's say a reflex/deflex 62 inch and maybe two common woods?
I can get ash and hickory walnut and purple heart easily.
Dont need a fancy thing just real numbers.
Is there a resource available?
Are there basic numbers?
Thanks!
-
Look at Roy's ongoing thread here on the bench. Or, a board bow??
-
What materials are you waiting for?
For a all wood laminated bow Hickory or maple (sold as a backing material) are good.
Osage Belly wood would be good, just use a darker core wood.

That Build along is what caught my eye. So where do I get the numbers for reflex and deflex?

Have you ever made a bow before? If not, an R/D lam bow is not the place to start, IMO. Make a board bow out of maple or red oak or hickory and learn to tiller a bit. Lots of guys don't like it much, but a straight grained red oak board will make a perfectly functional bow and costs $10-$15 at our local big box stores. Buy a couple boards and you have a couple cheap guinea pigs to work on and no loss when (not if, when) you break one or both of them.
As for lam bow woods, maple is a good backing and decent belly wood, hickory is an excellent backing wood and good belly wood. The really good compression woods (belly woods, that is) are yew, osage, juniper, eastern red cedar and ipe. None of which are common up here, unfortunately.
Another question - do you currently shoot a traditional bow (ie - not a compound)? Do you know what your draw length is and what draw weight is comfortable for you?

You have 3 topics up
You need to tell us what kind of bow you want to make?
What kind of bow are you making, It makes a difference, R/D fiberglass, R/D all wood trilam??? :thumbsup:
Ifthis is your first one you need to make a board bow like mm said

I used to shoot oneida eagle back in the day. Bow hunted Alberta for 7or 8 years and gave it all up.
I now own a Bodnik mohawk.
I also been a hobby woodworker for a while now with quite a few tools.
I figure I should be able to get a good start.

An all wood reflex/deflex. Just 2 woods and I can play with a tiller tree. Paid attention already to what Roy said about where to place the pulley. Made good sense to me.

That's the one thing that will get you in trouble building bows.
Shooting bows does not confer expertise in building them. And hobby working is a start, but there are special skills you need to develop for bow building. At the very least you need specialty glues -- Titebond or white carpenter glue isn't going to work here. Use Unibond 1:12 as Roy describes in his thread, or Thunerbird or Smooth-On EA-40, not hardware store epoxies..
You can use Roy's build along and substitute other woods for the Bamboo and Osage he talks about and substitute Maple, Hickory, Ash if you can get it, but no guarantees of quality and performance of the finished project.
-
I been reading alot for quite some time.
I believe I have the basics. I understand about epoxies. Just need some numbers to begin with so I can get my hands dirty. I already have wood in my garage waiting for a project. Ash, oak walnut purple heart and more.
I dont know the height of the deflex nor the reflex and at what points(out from center).
Is there a write up somewhere that I can't find?
-
I'm no expert but If you don't use Hickory or Maple for the back like I said above, I don't think it's going to work with a R/D style, maybe a flat bow.
-
On the first page of my BBO build.
I listed the materials, dimensions of materials, the heights and positions of my posts for deflex and reflex, along with pictures of the build.
If you don't have much patience, you may want to reconsider bow building.
Cause it takes a lot of patience to build bows.
And there will be failures, trust me there as I've lost several bows in my builds.
And you should keep notes on everything you do.

I can get osage for the belly. What can I use for the back?

Looks like I'm off to a bad start! Did I mention I'm a dog for punishment? Hard knocks is my middle name. Heading back to that first page. Thanks

If you want to build a lam bow to start that is fine, but make it a flat bow. R/D bows are vastly more difficult to tiller correctly and your chances of success are much, much lower. Lots of experienced bowyers struggle to get the bend right on R/D bows.
If you can get osage (where, where?!? :cheesy:) then hickory will make a good backing for it.
At the very least you need specialty glues -- Titebond or white carpenter glue isn't going to work here.
This is one thing I will disagree with. TBIII works just fine for gluing up all wood bows and I have used plain old yellow carpenter glue for all my risers and tip overlays with no issue. The oily tropical woods like ipe do need epoxy, but bamboo, maple, hickory, red oak and other typical NA hardwoods glue OK with wood glue. The prep needs to be done properly, but that applies to all glues.

Black forest has 4/4 osage in long lengths about 7 or 8 inches wide.

Outstanding. I really need to go for a visit now.

Where are u in central Alberta?

Two biggest enemies of the bowyer; impatience and power tools.

I need one guy to say, go for it dude! Dont be afraid to mess it up!🤦♀️
-
Go for it dude, don't be a chicken chit.
LOL
-
Patience is the key.
Go slow and methodical.
When in doubt, ask questions.
-
Thanks man! Appreciated.
Getting some angle iron tomorrow and will pick up some osage and hickory as well.
Gonna try and follow your bow build as best I can.
Is the reflex large on that build? So far one comment mentioned it's harder to tiller more pronounced reflex.
-
Reflex is 3" max out of form with 6 inch end posts.
You may want to start out with a 4 inch high end post.

Hey OldandSlow lets get the show on the road! AND post pics :clapper:
-
I'm on it. So far I have learned this is a no go without a way to sand lams. Gonna have to get jiggy with it!😳
-
What? Youre a woodworker! NOT a no go!
I built my first Hill bow with a circular saw, ruler, ferriers rasp and a chain saw file.
Come on man get creative!
-
I meant the lam tapers. Tough to get tapers uniform without some sort of jig. Turning a piece of wood into a bow is probably not so hard but I'd kinda like to make it shootable. Why waste a pile of time building it if not trying to make it shoot well?
-

Even if you can grind tapers you still need to learn how to tiller. A wood bow never falls off the form bending perfectly. At minimum it will need some fine tuning and it could need much more than that. Roy's BBO build will need significant tillering to make it into a bow. That's why I recommended you buy a couple boards and make them into basic flatbows as a starting point. They are the cheapest way to learn how to get a piece of wood bending and you aren't so invested that you will cry if (more likely when) one or both of them break on the tree or in your hand.

Kennym made my sleds
I made some short ones but it can be done on longer.
for a .001 sled 36" long, use two 3/4" x 37" long boards, sand both flat as you can, set one on top of the other, mark a line at 36" you need .036 thick shim between the boards at that line, at 18" you need .018 shim , at 9" you need .009 shim, at 27" you need .027 shim, secure them together and and run it threw a thickness sander of plainer. take it off and measure the thickness every 1" and see how good it is.
If there is some way you can get that done on a .001 and .002 :thumbsup:
