hello everyone tonight

Well here we are slowly working up to the upper pitman connection at the floor guide block

This is the way we did it----having turned the turbine shaft and the pitman to top dead centre and anchored it firmly, I moved to the upper level where the vertical blade, and its guide assembly is located--the next procedure is to remove the blade by removing the front wooden guides, and removing the single bolt attaching the bottom of the blade to the top of the guide block

Then the trick is to attach a light rope to the top of the guide block and pull the guide block upwards about 16" and securing it there--

Now going back to the upper split bearing of the pitman, the long slender key is removed and slowly slide upwards the strap off the top of the pitman, leaving the bottom half of the bearing on the top of the pitman, and taking the upper half with you along with the metal strap

Now you slip the metal strap through and over the 1" hardened steel bolt on the bottom of the guide block and slowly lower the unit back down over the end of the pitman, installing the upper half of the bearing in place at the same time

Once down in place the tapered key is reinserted and secured as previously explained

This completes the installation of the newly renovated pitman on the turbine shaft and securing it to the blade's guide block that is directly below the blade, and which is housed between 2 vertical hewn timbers that are secured firmly at their tops to the massive 20" square ash timber that spans across the building just below floor level

These timbers sit on other horizontal timbers, each vertical timber having a tenon exceedingly smaller than the mortise hole in all directions

I have been doing a lot of talking here so could anyone have a suggestion why the tenons on the bottom of each post is smaller than the mortises that they reside in?

enjoy
