I've had several emails plus comments here about sharing the plans for this. I'd do that but the originals got fried along with the hard drive they were on in an old PC I used. But I think I will try to duplicate the plans again and I will share them once I get them into a CAD format.
Incidentally, someone asked me about my CAD training and I replied I don't have any CAD training, but learned as I went along with a copy of Turbo-Cad 7.0 that I got on EBay for 5 or 6 dollars a few years ago. 2D CAD isn't all that hard and since I was primarily drawing rectangles it wasn't that difficult. But, if you're not aware of it, CAD lets you measure things "real-world" right there on your screen and you know immediately if the dimensions you're entering will work or not.
Since there's interest in it I'll try to add some regular updates to it.
All the best to all who've emailed and commented.
