There seems to be some good interest in a Smith Horn group build project. If you are interested, please complete the survey below to determine the level and type of "prep work" we're looking for. Throat Size: - 1" - 1.5" - 2" Pre-fab Components: - Vanes - Throat Plate - Body Vane Pre-fab: (What type of joinery are you looking for? A mortise joint will require an increase in the vane to account for the tenons. Dowel joints can use the same vanes as butt-joints) - Flat butt joint - Mortise joint Throat Adaptor: - Straight bore - Circular to rectangular transition Pre-fab Material: - MDF - hardwood Please add any other questions you think I may have missed.

Here's mine: 1" Vane Throat Plate Body Mortise/ either one is fine but I like the joint integrity of the mortise and I don't see why it would be a lot more money so why not? I would like to use one of my Altec drivers so I would assume that means rectangle to circle? If not then eithor one will do. Hardwood; I guess plywood is out of the question then? Baltic Birch? Looks good so far. Thanks for doing this survey Garman.

Oh, got you...:) Yes, 8 vanes. Probably 40-degrees included, or at least that is what my notes say. Now to get the good plywood. The issue I have is that it requires a 22.5 degree miter. With a serious tool shortage, this isn't easy to step around. The back plate/mount is quite easy by comparison...:) cheers, Douglas
