graphite carves extremely well, so any individual letter or short series wouldn't be that big of a deal, but how the heck do you keep it from breaking with the whole alphabet???
At the dentist a couple years ago I tried on the hygienist's magnifiers. It seems they were about 3x, with a decent depth of field. Their main advantage over an Optivisor might be the longer working distance, which was probably 10"-12". I can't remember the mfr, but they were pro grade and...
Looks like you may have start a 'history' for it. Engrave your initials and a date somewhere on it so 50-100 yrs from now people will be asking who you were...
:graver:
do an archive search. this topic has been thrashed to death over the years.
(Spoiler alert: They both get the job done, it's mostly a matter of personal preference.)
I almost forgot- there's a product called "Kroil", or "AeroKroil" in an aerosol can, and it makes Liquid Wrench look like 3-In-1 oil. It'll get into ANYTHING and loosen it, but be forewarned: It stinks. Use it outdoors or you'll smell it in your workshop for days.
Hi Greg-
Lots of good suggestions here. My question is, depending on the sort of work you plan to do, are you likely to ever need that pin? If not, saw/grind it off flush and be done with it. In my own work, I virtually never use the pins for holding anything (not even sure where they are)...
what Marty said. if you want your scope tilted a slight angle, the turntable needs to be tilted, too.
also, your vise needs to be dead upright on its donut. you might want to try hot gluing it to the donut to keep it from tipping out of alignment.
I don't do a lot of this sort of work, but big, bold, bright-cutting is one of the rare occasions where I'll hook up the Magnum handpiece to my Gravermax G8. You might try using a heavier/heaviest piston in your Lindsay and instead of making multiple passes establishing lines, etc., practice...
Allan-
YOUR story reminds me of two. Just recently a local upscale jeweler asked about engraving the winners' names, etc. on the base of a golf trophy and I gave them a quote. A few days later they asked if I would mind just working directly with the client because he's balking at the cost of...
that's not how laps work. the hard, sharp abrasive material embeds itself into the softer substrate (be it iron, lead, whatever), where it's held fast so it can abrade the harder material being lapped. it's kinda like you're creating a sort of sandpaper, with the grit stuck to one material so...
instead of just taking "a piece of copper and run it through the process", i would recommend doing a simple inlay in a steel plate or scrap part, to better replicate the full process. maybe put some fine/narrow points in the inlay, which would be most prone to damage. also, if you do larger...
I don't know if there's any official proscription against selling an actual firearm and/or part thereof on the Cafe, but this seems not quite the right place in any event. Anyway, many years ago I acquired a Hagn falling block single-shot action with the intent of building a rifle* (I was going...
"'fudge' the line spacing over a curve, so they stay more or less normal/perpendicular to the central plane of the sphere. done properly, the line spacing only appears to be fairly parallel, when there's actually a slight convergence toward the edges of the pattern."
to clarify, you want the...
i've been doing it with a single point (square) graver and a pair of dividers, then bringing the diamonds to full depth with a 4-sq needle file, for nearly forty years. over small, tightly curved surfaces, i think checkering files are worse than worthless. with a graver & dividers, one can...
