Ok, I'm kinda embarrassed to ask this... hahaha But when I was building my box for my next install into my car, I needed to make 2 angle cuts greater than 45 degrees. Our table saw only goes up to 45 degrees... So I matched up some lines and did it free hand with a saw. Well needless to say it came out close but theres still a goot 1/8" gap in some spots!!!!!!!!! Can I just make up a mixture of sawdust and wood glue to make a wood filler? I know it won't be "AS STRONG" but in recent experiences with elmers wood glue, the wood broke in other places than the glue joint. Which leads me to believe that the wood/glue joints are much stronger. I don't wanna seem like a "hack" but that was really the only way I could think of doing it... The box will have a lexan window in it... so you will be able to see inside but the location is out of view... I will also be painting the inside hite to reflect light...

Man I would think that would fine. That or go get you a tube of liquid nail, thats what I just put my box together with and I took a part that I cut out that was held together by nothing but liquid nail. I smashed it on the concrete trying to break it apart and all the wood broke except the part that had liquid nail on it. So I know that it is strong as crap man. But really I think either would work.

I believe that you can just us durglass which is a fiberglass reinforced body filler

I Personly would not use elmers glue i would do like realitycheck said to do, use liquid nail that is the strongest glue that i know other than Gorilla Glue They say that it is the toughest glue on the planet. I do some wood work from time to time and that is the only wood glue that i use. You can buy it at lowe's or home depot.

Set your saw to (90-desired angle) then run your material through vertcially against the fence instead of flat on the table. Clamp a scrap piece of board onto your metal fence first to both protect it & to give you improved stability (being taller)

I must have looked at that table saw for 20 mins trying to figure out something like that...

ANYWAYS... Thanks for the tip!!! Now I can probably use that technique to make the cuts almost perfect. Then join those together with liquid nails...

Cheers Bro!

One more tip for you - try Gorilla Glue - great stuff on MDF!

p.s. (can't edit!)

Follow the instructions - dampen the surface with a wet sponge first.

You can find it at Home Depot.

p.p.s

Use a finger board to keep the work-piece firmly against the fence - it's much tougher (almost impossible!) with a vertical piece to keep it tight without one.
