Best way to make a "rabbit" on MDF cut out for Plexi window with no router??

[RobWiz]

I'm going to be making a "step" (a rabbit I believe it's called) in the cut outs of my MDF floor in the hatch for Plexi windows. I'm assuming a router is the proper tool for the job. I don't have access to a router so what's the next best tool/way to make the step to lay my Plexi in??

Thanks,
Rob

If you don't have a router I'm assuming you don't have a radial arm saw or table saw...How about a regular circular saw? You can just cut successive passes with the blade set really shallow and eventually you should get where you want to go.

A table saw with a dado would work very well if you don't have a router. If you don't have access to one there is always the extremely inprecise method of using a a chisel which I have done before when I was too lazy to set up anything else.

The handheld circular saw would work but you better have a steady hand or at least a makeshift fence to guide off of. I have had too many bad experiences with those saws to recommend them unless you absolutly must.

How bout just using another piece of wood on top same thicknes as the plexi , Make it a little bigger than your cut out of the original floor(same size cutout as the plexi) and put it on top of the original floor and then you glass shall fit perfect !
