Hi, PK
What kind of wood is it? A self Holmie is totally OK. With white woods, I'd go wider in the working limbs. >2" would be better. Make SURE you've got a single growth ring on the back. I think 1 3/4" working limb width is asking a lot of a whitewood self Holmie. What weight are you shooting for? Less than 40# should be OK, but anything above is asking for failure.
It looks to me like you've done two seperate tapers in the working limb? Why? Make your working limb parallel or just slightly tapering its full length, without an abrupt step. Check out my build along... last night, I drew out the profile for a 66" hickory backed osage. Keep in mind that the working limbs on that bow are only 1.5" wide, but it's backed, and osage belly. Self whitewoods need to be wide. Good luck! Is this your first Holmegaard?
