[Public-list] Fw: toggles for New Mast Top

[sousa, stephen (ENG)]

Gord and Brian,

They are definitely toggles. I am going to be in the shop tomorrow morning
for some rework on the new stem head. I will check and see what part number
fits the mast head we used as the model. Either one of two things occurred.
I provided an incorrect part number or the tooling changed. I do not think
the design of the mast changed from the previous purchase. Will update the
list with this info.

Brian,

Thank you for providing this information to the list and assisting Chris and
Alfredo, the installation should be straight forward and not painful. 

Regards,
Stephen

Good morning fellows -

It sounds like you guys are thinking carefully about the project, but I
should suggest that use of shackles in standing rigging is not considered
prudent.  Are you talking about toggles?
