Stans Shaft Shop in Gulfport Ms. He builds all of mine and is top notch. Just tell him what its for and all the specs. and he can build you one that will handle anyting. His prices are very fair and has a fast return on orders. He has been in business in the same location for some 25 years and was only closed for a few weeks when Katrina put 12 feet of water in his shop. He is a real straight-shooter and has dirty hands... My kinda guy.
