Hi Michael,

>My plan for grinding two blanks with it is to proceed with wets on an
>A-B-B-A basis.

Consider efficiency of this scheme. Tool and blank tend to follow the same
curve generated by grinding. Using this tool for another blank will first
regrind them to conform. So it seems to me that certain part of efforts
will be devoted to constant mutual adjustments of tool and blanks.

Maybe for hogging it will not matter. But at later grinding it is required
that spherical shape is generated and for this sharpie test is used to be
sure that tool and blank are well matched. Proposed plan will ensure just
the opposite, constant unmatching of tool-blank. If this will nevertheless
be possible with one tool  and two blanks scheme remains to be
demonstrated.

Perhaps making second tool will better pay off .

You will certainly inform the list about the progress. It will be
interesting reading.

>He uses candle wax,
Usually this is reported as a method to fill channels between tiles AFTER
tool is finished to prevent carryover of grit to finer stages. Are you sure
Dennis used wax method to made  channels at the initial stage of making
tile tool.


Regards
Vladimir.
