Yet you scold paigoliver for voicing his opinion based on your opinion that you shouldn't scold people for voicing their opinion  ???

OSCAR, just curious: What is the cutting length & cutting diameter of your template bit? Does it matter? i.e. will any template bit with a top-mounted bearing work?


--- Quote from: OSCAR on September 01, 2004, 10:33:15 pm ---I also use plexi instead of lexan for exactly the same reasons that Randy mentioned.  I've used plexi for marquees, bezels, on cp's, etc., and I have yet to ever crack a single piece in the countless times I've cut or made holes in a sheet.

I do stand by the recommendation that a router is the absolute best way to cut plexi.  Well, other than a laser or water jet, but not many of us have that option.  :)

One other suggestion I would have is not to put too much pressure on the plexi when using a drill.  As the hole is being cut, you don't want to force the bit into the plexi faster than the bit is removing the material.  If you do, then you are applying a point pressure that may cause a crack as the material gets thinner right where you are drilling.

With a router the bit removes material so quickly and cleanly, I doubt it is even possible to cause plexi to crack.  When doing button holes, I use a template bit (the kind with the bearing on the top side of the cutter head) and clamp the plexi to the underside of the wood control panel.  Then I plunge directly though the plexi with the router bit (no pilot holes with a drill) and use the control panel as the template.  Some pics of this method can be seen at: http://www.oscarcontrols.com/sinistar.

Oh, I do a lot of "don't do that" posts. Many of them for good reason.

"Don't do that" posts from me will often pop up in these threads.

Any thread involving hacking multiple gamepads.

Any thread involving a mame cabinet featuring a brand new computer and an old 17" monitor inside a monster cabinet.

Any thread involving placing a large panel on a classic cabinet.

Any thread about converting a driving cab into a joystick cabinet.

Any thread involving an X-Arcade.

Some threads about plexiglass.

I don't like plexiglass, largely because it is conversion game fodder, and man does it start looking crappy quick. Real overlays do not get damaged during normal play, they get damaged from cigarette burns and from people peeling them off a bit at a time.

So when someone posts indicating they are having all sorts of plexiglass issues I will often chime in and tell them that they don't need it. I do this because many of the people in this community have no real memory of dedicated games, and think that real arcade games have plexi, when in reality it is really crappy arcade games that have plexi.

Any template bit should work, but I typically use a 1/2" diameter bit.  I think the bit is 1" or 1.25" long, don't have it in front of me at the moment.

For cutting wood I use a larger bit, like a 3/4" dia with a 1/2" shank, but that isn't necessary for cutting plastic.
