Replacing the Perch

From Chris Gane:

Geoff Campbell and I did another couple of hours on the perch yesterday.  Using a big jack-hammer drill we have managed to dig a hole about 50cm deep. My original intention of drilling out the old perch tube was abandoned as it was very difficult to hack around the metal with the drill and chisel so we have made a new hole, as can be seen by the photograph (below). The new perch is now finished with John Chapple having done a great job on the final coat of paint.

We plan to get out there with a cement mixer as soon as the weather permits and if we can fit it all in the small rowing boat! The aim is to have the new perch operational for the Regatta sailing on Thursday.

I have an appeal - unfortunately the stainless steel bolts that I bought are too short and some replacements are on order but may not come soon enough this week. Does anyone have any nuts and bolts between M12 to M18, minimum of 70mm long? They don't have to be stainless steel as we will replace them later. We need six.
