Title: It's only for practice, after all...
Post by: MattZA on July 12, 2018, 09:53:06 am
Quick question for you excellent folk...

I have about 7 feet of Garapa board lying around my house. For those that don't know it, it's similar to Ash (it's also called Brazilian Ash). The grain of the board is dreadful. Run off, minor knots, you name it.

My question is this: how much draw weight do you think it's safe for? I intend to build a pyramid flatbow with a silk backing.

I know I should just use different wood, but as an inexperienced bowyer I want to use it as tillering practice. It doesn't matter if it's slow in the end.

Thanks in advance!

Matt.

If you start with crappy materials you will probably end up with crappy results.

This is not the answer you are looking for:

I like your style, make it about 10% oversize and then reduce it slowly, only thing, using grain with run-off is usually a guarantee of an early failure, so try and choose the best of your bad-lot.

Oh I'm fully aware. As I say, it's simply to help me practice my tillering skills.

That, and I won't have any access to new wood for a while.

I honestly don't mind if I end up with a 20# stick. I'm just doing it because I'm tired of my poor skills ruining good wood.

Practice on the rubbish -> succeed with the good stuff.

  Simple answer, you don't have bow wood there so you won't be able to practice anything. If it has run outs it will break. Bow wood is very select wood.

I am actually on your side; when I started I had access only to very poor wood and I made a few bows from it, and they worked pretty well.  The guys on this forum were totally brilliant. I learned far more than working with good quality wood and now I'm addicted to awful timber and can't be bring myself to use the good quality staves I have managed to acquire but you have to be prepared for a really high failure rate (like 30% failure).  Run-out is the kiss of death and the bow with run-out will fail, you can work with pretty much anything else.

Its a waste of precious time you cant get back. There is nothing to be gained with junk boards, zero. A challenging stave is not the same as a junk board.

yeh, that's true, I was/do only use staves, I haven't built a board bow.

If you can find a piece of bamboo to back it with you can use crappy wood to make a bow, runouts don't matter on a bamboo backed bow, I have made a bunch of bamboo osage bows with awful osage, no failures so far.

Whoa, I certainly wasn't expecting such a strong response. I didn't realise it was an offensive question. I am new to this after all, and only looking to improve.

Thanks for the advice.

It shall become firewood.

When I first started I was afraid to use my good staves and choose the worsed ones & saved the best for later  and ended up with some pretty crappy bows in hind sight I should have did it the other way a round you would probably be learning ahead by using the best wood you have available , dont let these guys scare you ,there just probably trying to keep you from making the same mistakes they did  ;D

It's not an offensive question but neither are the answers. You have some very qualified bowyers here to help you be successful. We've all been here where you are now and we are trying to help you so you don't make the mistakes many of us did in the beginning.

The question was not offensive, some people just don't understand that bow wood is not always right at hand for everyone.

You can certainly can cover a multitude of sins with bamboo and maybe even turn out a bow with a lot of sex appeal on the belly with the grain of the wood. You could also increase the odds by backing with a layer of light, tight woven canvas and wood glue.  I have made dozens of bows from hickory with fairly bad grain run out by making sure the corners on the back were given a generous  radius and the canvas backing wrapped across the back and down over the sides.  Yes, I had failures. From each of those failures I learned something. If you don't have good bow wood ready to hand, and you feel like making shavings, do it!  Manage your expectations and exercise your tools.

Pat, I didn't mean to suggest the answers were offensive. I just meant that people clearly feel strongly about it. I was expecting a kind of "well it might be okay, but I don't know" kind of response.

I know and appreciate that there are some excellent bowyers here. It's why I posed the question.

After all the advice I think I'll probably just put the tools away and only take them out again when I have decent wood. Or maybe I'll use a bit of the bad board for some tip overlays. They do have a gorgeous gold colour that'll look excellent against my massaranduba red.

Sometimes an answer to a question is not what we want to hear.

Have you considered backing it with something?  This an unknown wood to me and may in fact be an excellent bow-wood

Where do you live, Matt?  Have you tried our Trading Post?

If you can go buy hickory axe handles, you have bow wood. 2 handles if good grain ( they usually are ) and similar ring structure will yield a 40-50 # bow at 26 inches using a take down sleeve.

Marc, I've used it before, and it seems to be a good wood. Not Osage, obviously, but slightly better than Ash, from what I've read. Definitely better than red oak.

Pat I live in South Africa, which complicates things. It means I don't have access to: red oak, maple, osage, hickory, ash, elm or yew. To all intents and purposes, the only readily available woods in order of quality are massaranduba, garapa, meranti, mahogany, pine (har har).

 Get some Massaranduba then.  It's very good bow wood.

I will when I get the chance. Fortunately it's pretty reasonably priced in board form. Costs me the equivalent of $5 for a board that'll make a 60" ntn bow.

I'm just not in the area at the moment. Hence the OP.
