Congratulations Erick, looks like a job well done! Don't just post your images - keep us in touch with the performance of the mount. I've been looking at barn door-type camera mounts, as I think I'd rather go that way than upgrade the lot. I've got a few ideas, different to your mount of course, and a little different to the one in the recent barn door thread on IIS. But I'd love to hear how yours goes - it's all a learning process.
Best of luck, and happy imaging!
Cheers -
