How to rout a perfect square?

[Twostrokeking]

I need some help. My new box will have two plexiglass windows and I cut them with a jig saw but my ocd is hating the look of them. You guys mentioned a jig for a router. How do I go about that? And then once the jig is on the 3/4" mdf what bit do I use? My dad has a router but it's not a plunge base. Any help is appreciated

Flush cut bit....I'm not going to be able to explain it good but

Assemble a square the size you want on one side of the box...4 pieces of mdf, than the flush cut bit will ride along the square you assemble. Look up how a flush cut bit works and you'll see what I'm saying

Maybe someone else can explain it

Build a square template to the size of the square hole you want, align the template on the piece of MDF where the square hole will be and draw out the square, rough cut the hole with jigsaw and leave about 1/8 of an inch space on the mark, use two-sided tape and align template with piece and secure the pieces, your fixed based router will work, just gotta adjust the height depending on the bit you have, top bearing flush trim or bottom bearing flush trim, top bearing the the template will be on top, bottom bearing the template will be on the bottom...hope this helps

Take a strait edge and after you cut your whole double side tape it where you want to route out and then use a flush trim bit to router it strait and do that for all 4 sides

Thanks man! What size of bit do I need? Length wise? I have a 1/2". I need a 3/4" right?

you need it longer, I use a 2" length bit...a 1" would suffice
