Title: Looking for a keel lifting block
Post by: Brian Denney on July 01, 2013, 12:19:37 PM

We need a new block for the for the keel lifting line. Any suggestions on where to get the correct one?

For the attachment to the keel eye, I use a Schaefer Double Jaw Toggle.  The line runs around the pin and I use a stainless bolt and nut at the bottom of the toggle to go through the bottom of the toggle and the keel eye.  I believe it is WM part 285736 3/8 inch.  You have to rotate the keel eye 90 degrees to fit into the toggle.  I tried a pulley on this, but the smooth stainless pin works just fine by itself.

Make sure you are not using Sta-Set X to lift the keel.  I had a line break on me once.  You really cannot see the condition of the inner braid with the cover.  Also a low stretch parallel core line does not make sense for this application.  I use Amsteel now.

Okay, here's what I use and it works great.  Made from a Schaefer tang cut in half and a small sheave using 5/16" bolts.  Let me know if you need specs for the tangs.  Pics attached.

The pics I attached in the previous post may not be usable, sorry, but I'm a computer illiterate.  Help!
Trust me, the device in the pics works great.

Schaefer Delrin sheave #62-020-02 and Schaefer tang #85-02 6"long x 1"wide (cut in half).  The two bolt are 5/16" x 1 1/2" or maybe 2".  The wing nut makes life easier and the jamb nut on the sheave bolt keeps things safer.............  Don
