ERC design suggestions (edit:pics added)
« on: May 28, 2013, 04:34:34 pm »
Got my hands on an ERC stave about 70" long and 2" wide. Three big dead knots / holes in it, not avoidable without grain violation (grain run out).

What is a matching design for ERC? ELB? Flat? ....

I think I can also split off a belly split, perhaps with 55"-60", about ½" thick.

All my erc bows have been flat bellies around 66" long. Seems to work well, I've never tried anything different with it though.

How wide did you make your ERC bows, I have some staves that will be ready in a month or so I'm itching to get started to work on.

I would say flat belly is your best bet I did see someone posted a cedar ELB with rounded belly but I have a feeling that wouldn't last to long

What? ???  Care to explain that prediction?  Or better yet, when and what scenario do you think a rounded belly would be appropriate?  Josh

I guess you didn't read what I said. I said I saw a cedar ELB posted on here with a rounded belly

I read it alright.  The part that I'm referring to is why you don't think a rounded belly elb would last very long.  What I'm wondering is if you understand what advantage a rounded belly offers?  That is the clarification that I'm looking for.  Josh

Ohh well I'm trying to say I don't think cedar is the best candidate for an ELB let's face it it's not very strong under the extreme compression an elb would put it under

Actually it's the exact opposite, ERC has great compression strength but poor tension strength. Perfect candidate for ELB's.
