I started and learned w/hammer & chisel. That was in '71.
I never gave much thought to giving that up, but I did fall to the GraverMax lure at one point and bought a machine.
That was in the 90's IIRC, maybe the 80's.
Everyone else had one,,maybe I should as well!
I used it a little but never felt really comfortable with it and it sat idle for many yrs till I finally sold it.
I continued using Hammer/Chisel. Most everyone else was on the AirAssist graver tool side of the trade.
I was doing work for a couple of custom gun makers as well as several other dealer and gunsmith customers. Working at it full time along with restoration gunsmithing.
Everything was going just fine.
Then two severe injuries happened to my head, arms & wrists. Plus other just plain age related (I suspect) things started getting in the way. I was to the point where I could not hold the hammer in one hand, chisel in the other and be assured that the hammer would make contact with the end of the chisel head each time.
Either give it up after 40yrs or do Something!
I looked at the Lindsay and bought one.
It was hard to give in at first (Dutch are like that) and give up the H&C, but it was the only way I could continue to work.
It allowed me to continue to engrave and produce work and I still do to this day.
Almost 55yrs at it now.
The Lindsay is a very easy tool to learn to use. Very controllable. Results can be realized generally much faster than with hammer and chisel.
How good those metal cutting results transform into artistic forms is up to you however.
It still takes patience and practice in drawing, shading, proportion, layout, etc of course.
Expensive,,Yes, but if you are really set on following the trade and producing work, it can be for you.
Once in a while small jobs on projects that are not too intricate can be easily taken care of with some skills in handling the old hammer and chisel,,and at a lot less cost to you.
