@porkysplace - If things go right, I will be able to make these to order. I've found a new supplier for material, so I won't have to buy in bulk; I'll be able to buy only what I need. In other words, don't worry about pre-ordering. If you want one, you'll pay using Pay Pal, then I'll ship the top. This provides insurance for both parties.
@doghead - This is a feeler. That means I'm measuring interest and taking feedback before starting on/investing in prototypes. There is no need for a group buy on this site as I will be giving SS discounts. I'm not sure why I would need approval to give people a discount, anyways. Are you needing a top/tops? Do you have any preferences/suggestions for how it would be built? That is what I'm after here in this thread.
As far as everything else goes, does $200 seem reasonable for a junked old M35A2 for turning into a welding jig?
