I just finished finishing this. So now it's mostly finished.
It is vine maple with simple self nocks and the ridges on the back highlighted with some dark walnut stain that was rubbed down with 400 sandpaper to bring out some contrast. 66.5 tip to tip . It is a bit lumpy on the back (hence the name). Grip is jute twine and superglue. rest is a leather flopper. 56@28. Finished with stain, and 7 coats of danish oil and rubbed down with paste wax. Shoots great.
Additionally, the temp was about 16 degrees. selfbows work fine in the cold.
Thanks.
