If you are using traditional hook system for attaching your cables to the mast here is an idea of how you can install the “nose” hound type.
Step 1
Prepare the fitting. Fillet the edges and tap two holes. I tap 6mm thread.
Step 2
Prepare the mast to accommodate the fitting. Make sure you get all measurements right. Remember – measure twice – cut once.
Step 3
Apply glass reinforcement on top of the fitting. I use 6 layers of biax 300g/m2. I use black dye to tint the resin – after excess resin comes out it looks nice from the outside.
Before glass comes on I install two 6mm studs to keep holes opening clear from fibers before putting default screws.
Step 4
Drive the fitting into the mast. My favorite way is using thin cords (due to limitation in shop space). One cord to pull nose in and the other to take cart out. Notice pull in cord is attached to nose. Once the fitting is in place it will be used tu lift it up.
Step 5
Pull the cart gently inside the tube and lift it up. Have some sort of clamp ready. Once the nose shows up clamp it, remove temporary studs and install screws.
Clean excess resin and leave it overnight.
Step 6
Trim the studs – be careful not to overheat if you do it with angle grinder!
And you are ready to go!
Since some years this system is installed on all Moore Bro. masts. It greatly improves mast rotation and lasts forever.
Last year I had a chance to see how in reality mast hound is fixed to the mast wall from the inside. Here is is the picture:
Before I enter the hound into the mast I apply 6 layers of glass biaxial 300g/m2. The purpose is to fill the gap between inner mast wall and hound. The result as you see is perfect. There are no air pockets and fit is as expected.
And this is how mast hound looks like prepared to receive glass and resin.
I will make a separate post on how to install a hound step by step.
