Title: IPE
Post by: Buemaker on November 26, 2018, 01:33:09 PM
Does anyone have any experience with this wood as a belly wood?
I have some straight stuff without any pins and blemishes.
I think I heard that some people react severely to sanding dust from this wood.

No experience making a Bow with Ipe, but it makes a great deck! The stuff is hard as hell, really heavy and will dull a saw blade faster than any other wood I have worked with.

Yeah I do.  It's a great belly wood.  The best IMO.  Osage is great too, but my ipe bows are always faster.   

What kind of bow are you looking to make with it?

I haven't had any reaction to working with it, but either way make sure you wear a respirator.  It has silica in the dust; really bad for the lungs.

I was thinking a trilam ELB and perhaps a flatter design with bamboo on the back.
What design are you making BMorv?

I made a few tri lams with it.  Some bamboo backed bows too.  I'm working on a bendy handle ipe/bamboo one right now.  It doesn't take much ipe to make a bow. 
It works well in almost any bow style, but I really like it in a tri lam.
The bendy one is the 1st pic and it's only 7/8" wide.

Looking good. :)

Those are looking good! I've got a bunch of Ipe off-cuts, guess I'm going to have to dull some tools with it. Wonder if it will make a decent lamination?

It makes an excellent lamination.  I haven't made ELB style bows with it, but I've seen people use it for cores in that style.  I think its best used as a belly though.
I've had the best luck with the really dark brown colored ipe boards.  I weigh the boards I get and those seem to be denser and make better bows.   

If you think ipe is bad on tools try purple heart.

It makes good riser ibeams.

What is the best way to treat it before glueup, and what kind of glue is best. Thanks.

40 grit sand paper for lams or toothing plane for riser parts.  I've used TB3 and Unibond 800 both with good success.  I just get the dust off with a rag then use my shop vac to get all the fine particles off. 
You'll see some things online suggesting that it's very difficult to glue because of the oils; not sure if these guys ever actually tried gluing it  :dunno:
I've never had gluing issues with it.  I treat it like any lamination.

There is a really good BBI buildalong on poor folk bows and he talks about Ipe a bit. Here is the 
link. (http://poorfolkbows.com/ipe1.htm)

I have a board of it rescued from a deck that is begging for me to make a few bows out of it. Just need to find a good place to get bamboo backing strips

No more IPE in my shop.

It really messed me up bad.

I still have lingering health problems after the initial exposure to it 10 years ago.

Man sorry to hear that Roy.  Was it lung related or was it part of an allergic reaction?
Title: Re: IPE
Post by: Roy from Pa on November 27, 2018, 09:27:11 AM
allergic reaction
Title: Re: IPE
Post by: BMorv on November 27, 2018, 09:33:33 AM
I wonder if there is a way to slowly or lightly expose yourself to ipe to see if you are allergic to it??? 
No bow wood is worth lingering health issues.

I really don't know.

I got a very high dose of the IPE sanding dust on my face for an extended period of time, like 6 hours.

Looked like I fell into a fire pit that night.

Several trips to dermatologist, steroid shots and pills for a couple years and now use of a hand cream a few times a month as needed.

Free and clear laundry detergent, dryer sheets, hand soap, and shampoo now for the past 10 years.

It messed up my immune system..

Roy, that sounds really bad, I better be carefull. I took a small dose of the stuff yesterday and feel no ill effects.
The wood dust thing can come creeping up on you, I have worked Yew wood for nearly 30 years and for the first half felt nothing, but now get a headache if exposed to Yew dust. I try to sand it outdoors.

Yupper, Bue.

Protection is the best defense.

Black walnut gave me a bad bronchial tube infection 2 weeks ago.

Just got me a new respirator last week.

Yew bugs me just a little, but even a heavy dose of Osage dust causes my hands to get dry and crack now.

I wash my hands after every sanding sequence now on Osage.

Seems to be helping.

Heck I darn sure don't wanna start making them glass bows.

LOL

I know a few folks that can't be near ipe for the same reason as Roy.
 Ipe and boo or hickory backing makes an excellent bow.

What is the size of the piece of ipe?
