Why not just use a drawknife for the whole thing? Seems the most logical, as there's no risk of sawing into wood you need, yet the drawknife can hog off a ton of excess wood if you're careful enough. With a 4" sapling you could rough out both limbs leaving a handle in about 30 mins.
I just came in for coffee and read this.
I've been in the shop for 30 min. I can hardly lift my coffee cup. I made the 2 cuts for the fades and split off the belly side as far as it would go. It came to the surface at the tips. I clamped it in my Workmate and started dragging it around the shop with the drawknife. There are a couple of knots on the belly side toward the tips that I thought I could take off safely. I honestly think it's going to take me the better part of 30 min to get though each knot. You must be a whole lot younger than me. There can be no doubt you're in better shape.(Wikipedia uses me as a bad example).
Anyway, my plan in splitting the stave was to discover how much twist there was in the stave so I could follow the grain while roughing. I plan on steaming it straight. Now that I've established that there is a shipload of twist I have to follow that with the drawknife. It's not as easy as I thought. Aside from my physical lacking my eyes want to carve it flat.
Coffee's gone. Out to the shop to figure out how to tie down the Workmate.
