I’ve been gone for the past month for family reasons, so had to suspend my work until now. Just before I left, I received my new Lindsay Nitro G20 AirGraver, and had just enough time to play with for a few hours before leaving.
Here’s a close-up of it, courtesy of Steve Lindsay’s web site: http://www.airgraver.com/Hand_Engraving_Tools_Overview.htm This AirGraver has considerably more power available then the excellent Lindsay Classic Palm Control AirGraver I already have. I’ll be using the Nitro G20 for heavier engraving and metal carving, as well as heavier sculpting by forging shapes with punches. I also have a notion to eventually use it for wood carving as well, although I’ll have to figure out how to forge some carving gouges and veiners.
Of course, that means another set of gauges and controls to be added to my Lindsay Classic Palm Control AirGraver setup. Above, you can see the major pieces involved in this plumber’s dilemma, along with my Lindsay Classic Palm Control (lower left) and the new Nitro G20 (lower right). The G20 has a foot control, and I’m happy to see that. I find stippling and sculpting with punches a pain (literally) with the Palm Control, since I have to hold it in an uncomfortable manner in order to activate it in sculpting mode. The foot control on the Nitro looks like it will eliminate that problem.
Here is my solution to the Kobayashi Maru no-win plumber’s nightmare scenario… I used brass plumbing fittings available from my local Ace hardware store, and some of the supplied Lindsay pneumatic tubing. Since I couldn’t find small enough fittings locally to fit the pneumatic tubing, I had a small stroke of brilliance and used a drill bit to drill out the inner diameter of the tubing to fit. Since my compressor can’t make more than 90 psi, this should be fine. A little hardwood and a Forstner drill bit, and, Eureka! It works. Palm Control on the left, Nitro on the right, both immediately available and downstream of the coalescing oil filter.
Now to get back to work.
