To add to the pot.
0flute 1/8" upcut 100 IPM straight plunge (ramping would break the bit) Widgetworks Presure foot with air nozzle to blow the chips away. .060 half hard polished brass cut face...
I used one of the older ones which was a good tool. This current version, I had purchased and setup for acrylic fabrication with a router speed control. Worked outstandingly well. Good investment.

Let alone half of the other things he's doing in his shop. I'm surprised he has all fingers let alone still alive.
Wow, keep this guy away from a CNC
This is a checkering effect i used to use for signs. Simple 45 deg pocket mill with a 50% stepover with a ball nose bit. Then repeated at 135 deg.
Nice job. Glad you decided to play with it.
No problem, glad to share.
The bit is an upcut 0flute. I've tracked down the number, Onsrud 63-510 1/8 dia 1/4" length of cut and 2" overall length. As i said, it's meant for acrylic. It also has a less aggressive shear angle...
The spindle is set to Mhz. I had a base line of 4500 Rpm @ 300 Mhz and 1500 Rpm @ 100 Mhz approx. It cut best at 186Mhz on the spindle control. The overall trick to cutting with such a small dia bit...
.060 half hard brass sheet, polished one side. Cut face down with vacuum and widgetworks pressure foot. Bit is onsrud .125 dia x 1/4" zero flute. I can't remember the number off the top of my head....
The final bitmap is a .tif exported from my paint software at over 2100 x 468 pixels and 1.9 MB. I increased the resolution to 89 pixels per inch to maintain the approximate size of 24 x 5.25 Inches.
Jack, i fixed the bitmap
unfortunately it's too large to attach here.
Jack,
THat's why i increase the size of the graphic exponentially. If you apply a blur to an image that's 600x400 compared to 3600x2400 the effect is vastly different.
Regards
Jack,
I use paint.net to increase the resolution then apply a gaussian blur that will smooth out the pixels. From there I apply a grayscale filter and adjust the sharpness and contrast to my...
Update.
The inlay project is a go. I post pics when it's done.
Actually, this is my first attempt at inlay work with a drag knife. I've been doing vcarve inlays in wood for a few years and i'm going to be trying that technique in 1/8" acrylic soon. This success...
Hey guys,
I've been playing with a Donek Tools drag knife at work. Mostly it's been cutting styrene and other shade materials. Friday i had some time to play with some styrene backed fabric and...

As far as I know, the only way to convert shopbots over to Mach3 is a new controller. I've done it myself simply due to cost of replacing a missing controller. With that, I don't understand why they...
More acrylic and LED work i've been doing at my current place of employment.
[QUOTE=scottp55;158406]Randy, any more info about that pic? Has anybody ever laminated and carved old cd's and carved and lit?[/QUOTE
The sign was 4ft x 12 ft approx 1" thick polycast acrylic...
Yes, Polish the edge that receives the LED.
AJ, I'm feeling like an old man on here. Has it really been two years?
(yes i know i'm a young buck in actual age compared to some)
Jack,
Attached is a screen shot of how i would setup mt dadoes and rebates for use with the kreg jig. Full 3/4" construction. Everything locks in nicely. The toe tick is attached up to the bottom...
