The patent on the foot control Lindsay expired on July 18, 2021, and the patent on the palm control has an anticipated expiration date of October 9, 2022 according to the U.S. Patent Office website.
I would love to have a Lindsay or GRS system, but as someone just dabbling in the art, it was...
Thanks for the tip on silver engraving PS. I haven’t graduated past practice plates ( actually fender washers) yet, bit it makes sense that softer metals may need to be engraved to account for wear.
Allen and Monk,
Thank you for your replies. The knowledge and resources that are shared on this site inspired me to give engraving a try after decades of admiring the art of engraving.
I spent over a year reading thousands of post, saving images, and drawing before I picked up a graver...

As a complete novice, I’m not sure which would be more helpful in improving my design skills. Any recommendations would be...
The graver rotation post recently added by Allen Clapp should help. I’m new to engraving, and I’ve never actually seen Lindsey templates, but from the pictures I think they may be more like a 129 degree graver with a 116 degree heel angle. I’ve been wanting to ask about the actual angles, so I...
Allen,
I used your table this morning to create a templet for parallel heels on a 120 degree graver. Thanks for creating the table and sharing it with all of us.

I am just beginning to try my hand at engraving, so I am as far from an expert as anyone can be. However, hairspray is what I use as a base for transfer. I spray practice plates, then let them dry to slightly tacky. I then stick plain paper laser copied images on the tacky paper and lightly...
