I have been trying to get Sierras from Darryll for over two years. He has 50% of my money and all I have are empty promises..'nuff said about Darryll. Do you have any photos or prints of your retracts that you would care to share? I'd like to put my mill and lathe to work.
I have scaled up Robart's rotating retract head and like you said it was tight. I can move the plate were the gear mounts and gain a bit of wiggle room. Just got a nice bunch of outstanding quarter sawn Sitka Spruce from Aircraft Spruce for spars. Outstanding buy at $37 bucks. about 30 pound of boards from 14 inches to 51/2 feet.
Thanks Richard
