I'm completely lost on what size/type router bit to use

[bikinpunk 10+ year member]

I'm wanting to put 1/4" plexi on 1/2" MDF false floor to show the amps underneath. I have an older Craftsman router, but I have NO idea what type/size tip to use? I've never used a router in my life, so this will be a laerning experience. I've seen alot about rabbeting bits, and those seem to be what I need, since they help guide along whatever surface I'm cutting? Or do I use spiral bits? Help...need to make it to HD before close tonight.

Yes, rabbet bits. Look for a bit with a small wheel on the end of it. Spiral bit's OK but it'll go allover the place w/o some kind of guide.

forget the guide, use a metal meterstick and 2 "C" clamps and save yourself $$$

I've been using the same basic steright 1/4" bit on my router ever since i owned it with excellent results.
