The final design problem solved! Rummaging in my odds and ends box I found a bag of these
I can’t remember when I bought them or what job I used them on, but I seem to have hung on to a couple of dozen spare ones. For scale, they have a six mm thread in the round end. You screw them into a pre drilled hole with a hex key. (Sorry to insult the intelligence of DiYers, but some reader may not be familiar).Well, just the job for my roofbox ridge pole. I sunk them into the ends of the pole like this. That’s a 28mm dia pole.
In my bits and bobs were some nice 6mm screws with wide domed heads and some washers, and hey presto:
Job’s a good ‘un as they say. Rigid, but quickly.removable. I didn’t even have to splash out a couple of quid on a broom handle because my old ridge pole, although marginally too short for the old design, is fine for this one.
Kath has reinforced the sewing on the cover, and it fits (phew!), so apart from a few little cosmetic jobs ( e.g. screwing on some bungee cord buttons, ooh and mustn’t forget the tv aerial bracket)) we’re done and dusted. The floor board’s from the old box are a loose fit, but that’s fine, they’ll let any water out.
I got a gentle reminder (thanks) from Marilyin McD to slap three coats of paint on those bare wooden leg tops. Little does she know I have already sneakily applied three coats of yacht varnish, which is better for that job and won’t be seen from the outside.
Is it straight out to Herbie to install the box then?. “Would that it were” as a certain TV presenter might have said. First I have to repaint the boat roof where the old box stood. Not a quick job because inevitably the box feet took their toll on the paint. When will it ever end?
