Nick,

Phill has the answer. The only issue is access to inner rear beam bolts if you need to separate the hulls again for any future work. An alternative design is to buy a flat section traveller track that you can drill a hole small enough for an allen key and use cap screws instead of bolts. Then you can remove the track and beam together and never have to go through the process of fumbling around blindly for the inner bolt heads. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" /> The inboard bolt holes in the beam needs to be just big enough for cap screw head and the hole in the track just big enough for the allen key.

I've seen this design used on a number of newer Mozzies and it looks great and works well. You can also regularly check bolt tension without any fuss.

The alternative is to keep persevering with long ring spanners and a torch for accessing the rear beam inner bolts.

Regards,

Peter
