Hi Tim -<br>
<br>
I thought we agreed that the plastic feed-thrus were ok the way
that they were. We<br>
agreed that we would ream out the end-plate to spec (0.4375) to
accomodate them and all<br>
the fits would be good. We did not want the OD of the new feed throughs
changed. <br>
<br>
The only change that we wanted was the ID of the pin holder
increased (to just shy of 0.050) <br>
in size to accomodate our chain for stringing the wire. <br>
<br>
<br>
I indeed hope that we have not changed the feedthrough OD, we
definitely did not want<br>
that done ....<br>

I know the previous email said that all the holes in the carbon plates
will be reamed. I assume a .4375 inch reamer? At the same time, the
plastic feedthrus that are inserted into the holes are being corrected
to bring them within the .4360/.4345 inch required diameter. This will
mean there will be .0015 to .003 inched diametrical clearance between
the parts . This is just a heads up since the original requirement was
to have these a line to line fit.
