Jerry,
Apparently the item he is talking about is similar to a Craftsman sign maker. Following is his post from the other forum:
I was the recipient yesterday of a gift of an E-Z-Router sign maker from a very generous woodworker. The frame is like new but here is the problem.
There are no letter templates with it. There were some from a different system that do not fit. I cannot locate the manufacturer, E-Z-Router and the company it was bought from is no longer in business (Trend Lines) so I can't contact them. There are no instructions either but there is some advertising material that indicates that there are 2 inch and 4 inch letters and numbers available and there is also an instructional video.
Do you have or do you know where I could get these missing items?
