No on Liquid nails... and if you are using a circ saw, you really should use a guide. Straight pieces are KEY to a good build.

and plenty of clamps...

Perfect cuts every time.

You can use that same method except angle the blade on your saw for your 45* cuts. Then cut the pieces to length.

thats how i do it. awsome

**** wish I knew they had a guide before I spent that time cutting some pieces LOL.

That aluminum guide only cost a few bucks at Lowes. The pair of clamps were like $20. They're well worth the money.

teh hell with liquid nails that sh*t is poo use titebond wood glue

 

[tyler_fitz 10+ year member]

liquid nails for glue. most circular saw and jig saws come with rip gids to help with straight cuts. i would also recommend corner clamps a least 2

WRONG! It actually says on the label not for use on MDF...

What type of circular saw blade do you guys use? Do they make them MDF specific with a certain style and teeth count?

Well today Im going to pick up some things from Lowes to start my build for my 2 12" HDC3's tomorrow. Also to pick out a new circular saw my girl is getting me for Birthday. So Im more or less looking for pointers or any techniques people use into making these boxes. They seem straight forward, only thing that bothers me is how do you cut the wood, or even cut it with, that goes into the corner of the box that helps with the air flow. I know its suppose to be at 45 degrees, but is there a special tool you use to achieve that? Also does anyone have any recommendations on glue, circular saw, jigsaws, etc. they use and like.

Get a Tablesaw. /thread

Nah, you need a guide... and a good design.

As for the 45* angles, most people don't do it properly... and it ends up being more of a detriment than a help. You're SUPPOSED to make it so that the port is the same width through out the whole port. (That's the point of them, and to ease the moving air for the turn) You have to cut the other side of the port to make sure the port is the same size through out the whole box. It takes a lot of work, actually... a lot of miniscule cuts to get it perfect... which most people don't do... and it ends up bottle necking the air.

But the 45* angles will be tough with a table saw. Unless you make them wide, then it won't be too bad... but you'll have to take more off the other side of the port.

VERY true. You're one of the few people that seem to know that.

OP - Check it...

Pretty cool thread. I can see I have a lot to learn before I attack my box build this summer.

I actually learned it from you. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I saw one of your threads and I was like, "Wow, that's really dope." Then I realized that if you don't do that, the port width isn't the same through out, so it ends up compressing at the elbow.

your first box most likely won't be that great and will need lots of caulk(unless you have an awesome table saw with huge extensions on it) The more you build the better they get.

Mods should sticky this. This is good info

Haha, that's some funny shit.

Not only does it affect flow (even if it is just minor) but the port area changes, thus changing the tuning.

When measuring port area for square ports, width is obviously a factor. When calculating, you're assuming the width is the same the whole way through the port, giving you an accurate port area, and your desired tuning frequency. If the width is changed at all, it changes the area.

This may not be super important all the time, but for the amount of times that i've seen it neglected, it worries me.
