I have
Made a couple of bats, the first was a small tradionally shaped bat which i wasn't impressed as the cleft had split down the back of the bat so by the time i took out enough willow the bat had a shallow spline.
The last one i made was a real success, was a 1000 times better than i could've imagined producing, here are the pics of it.
The bat weighs 2'10 and is a Grade 1+ with 12 straight grains. Was going to keep it for myself but decided to sell it. I'm waiting for a delivery of willow so i can make one for myself.
If anyone wants any advice on making a bat i'll do my best to help, i'm still a complete novice myself when it comes to bat making!
