    I was finally able to actually start on the clone project this week. The first thing I did was to build a saw guide for the ole Skill 77. The table saw proved to be almost useless because of the odd shapes needed for these cabinets.

    The tweeter rings could be improved- the hard transition to the bulb is not ideal. It'd be better if the rounding transitioned smoothly to the tweeter flange, so there's an opportunity to add a little flair.

    The tweeter bezels are without doubt the most difficult part of the clone process. My first thought was to attempt to turn them on the lathe but my skill level is not up to task. " A guy has to know his limitations". I will fabricate a jig system for the router table and see how that goes. To reduce the tendency to crack, I will laminate the material instead of using a single piece. I am probably going to use Jatoba (Brazilian Cherry) on one pair and maybe Rosewood or Bubinga on the other.

    That's what I did although mine were going to be painted so that made it alot easier.Rob

    Greg did tell me at the GTG that they were a bear and the guy who made them came up with a very good way to make them and then cut them at a 15deg angle like Rob has done above. There were no CNC machines at that time!!

    Nice job Guys!!

    I would recommend that anyone using Rob's rather clever and fairly simple method use a round nose router bit with a 1/2" shank if you can.

    Rob, I really like your jig system. That sure beats the ole brute force belt sander method. Thanks for sharing.

    Widget, that's a great tip. I just happen to have a set of round nose burr bits from a duplicator project.

    Hello Woody

    Your welcome I can't wait to see how yours come out. Your horns are always beautiful so I am sure these will be mint!

    Hey Woody...
    Glad to see you are able to start working again on this project, and they look awesome so far!
    Thanks again for taking time out to fabricate for me my "clone" 250 Ti grill frames!

    After loosing momentum I was finally able to slap a coat of oil on a finished 250 cabinet. Another year or so and I will have those babies ready to go.

    Absolutely WOW! They look fantastic. Can you share with us how you install the quarter round molding on the cabinets? Do the panels leave gaps for the moulding to be installed, or is the moulding integral to the panels?

    Obviously, these are questions from a complete novice.
