Method
We (my friend Dan and I, he really engineered the project)drilled two pilot holes through the top and the headliner. Then used a three inch hole saw to cut the headliner. We used 3/8 inch threaded rod (two per side). Counter sunk the holes at the top of the feet, used a nut and washer on the top. Drilled two holes into 1x1 angle aluminium (about 10" in length, again one for each side). These were run port/starboard to dicipate the stress across a greater area of the top. The rods were passed through the angle alu. and nutted. The threaded rods were cut to size, deburred and ends rounded to accept the nuts (sometimes I to thank my Coast Guard aviation metal working days). The setup has worked well. The traveler is through screwed the teak cross piece (track support if it needs a name). I love the look of the teak over metal or plastic. Cetol requires mimimun of maintenance...I a going to post a couple of clossup pictures soon. You can e-mail me at ggarner_gds@mindspring.com (or here at this site) whenever you want...
