FLUID POUR & SET
12' Rotary Mattison Grinder
This is a saddle off a 120' rotary Mattison (Blanchard-type) grinder. This saddle is 26'6" total length; however, the bearing surfaces are only 11'3". The bearing surfaces are rough cut for adhesion and shims were glued to the surface for rough alignment.
In this picture a 11'2" area of bed has been taped out for molding. The oil groove pattern in the bed has been filled with modeling clay.
Wax paper has been laid over the molding site to keep dirt
off of it while other work was being performed.
Last minute cleaning of bed ways before applying the release agent.
Close view of bed vee way shows that tape was used at tops of way surfaces to create a draft for any excess Moglice. This eliminates the risk of excess material from bonding to vertical surfaces of the bed way.
Old oil grooves in the saddle were filled with Moglice Putty
so they would not trap air during the pour and set process.
Overhead view of prepped vee way. By not installing end dams until just before applying Moglice, it is possible to blow out carefully, with air, any debris that may have fallen onto the vee way.
Installing dams at the end of the vee way,
made from cardboard and taped into position.
After pouring Moglice into the dammed area, it is spread out and
crowned toward the center to reduce the chance of air inclusion.
A closer look at evenly spread and slightly crowned Moglice 628 (semi-putty).
Moglice FL/P (fluid) is poured into the vee way.
Moglice is spread in the bottom of the vee way
in order to achieve a uniform depth of material.
