    GRS Gravermeister restoration, modifications, help

    GRS may not be able to help you......I read recently somewhere (here?) that GRS is no longer offering the valve upgrade, at least in-house; apparently they were having warranty problems. You may still be able to get the kit for your own use, however. Can't hurt to try.

    Question: Andu Engraver

    Is all this concern over powered equipment a sign of the "I want it now" mindset? At least a rudimentary understanding of the hand process would be an asset in understanding the art........which I doubt you would get by jumping in with power tools.......

    magnification

    I use a Zeiss OPMI, which uses a fixed final objective and an interior magnification changer. Given my current setup, those magnifications are: 4,8,12,20 and 32x. Most of the time, I am using the 8 and 12x settings, although for really close work, the 20 and, occasionally, the 32x get called...

    Draw File

    I believe that Brownell's used to carry them, but no longer. Nor have I found them on any industrial supplier's site I've checked, at least not as a "draw file"....... As a possible substitute, you can look at the chain saw sharpening file you can find at Lowes or Home Depot. The "brand name"...

    Gravermeister oil choice

    10w is the recommended oil unless it's low temperatures, then go to 20w. It's in the manual, you can get it from the GRS site, in the support section. There is also a note about using Dexron ATF if oil sludge is a problem. I use ATF in mine, without any issues. You might also need to either...

    Help, please: old gravermeister advice

    Here is a very old (seems to be dated 3/87) 4 page document from Gast, listing parts and a very brief bit of maintenance information. If you contact Gast, you can at least give them the part numbers, and, just maybe, they may have some in a box on the back shelf in the warehouse. By a process...
