Hi All

I've made my own stainless steel mast base plate with the rotation arm sweeping the tramp (a class style). I'm also going to have a hinge to raise the mast solo.

I just wanted to find out if anyone knew if the socket which is mounted onto the front beam actually goes through the top surface of the beam and into the striker post, when setting up the beam, instructions I have for the main beam assembly said to drill a pilot hole for the mast step, the fitting socket fitting I think I'm getting from AHPC, will be threaded so as far as I can tell I will need to tap a thread into aluminium plug in the striker post. I hope this says what I'm trying to say <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />

I assume I make a stainless plate which supports the mast socket fitting on the beam, after I've fitted the hinge under the socket, is it welded to this plate or screwed in tight?

I think I know the answer to these questions but like a second opinion or the correct answer if I'm wrong

Thanks

Matt,
The plate should come with it.
You are correct in as much as the current system they are using requires a thread to be tapped into the Aluminium plug in the top of the striker post. Unless they have updated the plans they are referring to a previous setup hence no mention of cutting a thread into the aluminium plug.
I think there is an unthreaded step in the beam fitting which is a cone. This allows it to be screwed in tight and still allow the hinge to rotate.
The socket goes onto the mast base.
Hope this clears it up.
Regards,
Phill

Yes, thats the answer I'm looking for. I should have thought about my post a bit more before submitting, because now I do remember the socket is on the mast.

I just wanted to clarify the fact that it was threaded into the striker post.

The plate that comes with the cone, it just surrounds the cone? as a support for the fitting?.

Many thanks Phill
