Since my wife will probably kick me out when I'm done you could just call this the "double wide" in honor of my new home.

Ok I ordered in my track saw today. Once I get everything up and running I'll start posting some pics of my box progress. Still haven't decided on what wood to use, but I'll probably buy mdf and try to use the track to trim the inch off.

The ones I've looked at from home depot and lowes look perfect. Just take a tape measure or something and measure it to see if it's good.

Plus one with this. Even my friend whose a framer won't spend his money on new saw unless its a makita.

If you build it out of MDF that box will easily weigh 200lbs

MDF - 200lb box could be a good thing it shouldn't move around too much..


This might be the box I was looking for I still have some time before I decide.

The cabinets I built are only 32"wide, 22"deep and 40" high and are made out of plywood and they don't move around at all. I built two from plywood and the second two are built from Superlite MDF, neither sub move at all.

Hey there, jbrown! What was the weight diff between the two matched sub cabinets, but differing materials?

I didn't actually weigh them on a scale but I would say that the Superlite MDF was a little lighter then the plywood that I used. Both cabinets had lots of bracing and were easily strong enough for me to jump and down on if I wanted too....lol

Superlight mdf is 62lbs a sheet. Plywood is around the same.

Looks like my saw will be here tomorrow! But I'm too broke to buy wood right now. Oh well, next paycheck I can get started. Might have to start dropping all my old gear on ebay.

So what do I use for measuring long cuts? Do I need to buy a 4 foot square or use a tape measure?

Your track saw should have came with a track that will make the long cuts straight. Just measure on each end of the cut and place the track in place, clamp it down, and rip the cut. It's the easiest cutting tool I've ever used. If don't want to use the track or don't have a long enough track then use a factory edge of the sheet of wood to draw your line and after you rip the first piece you'll have that factory edge to draw any other cut lines.

Oh and make sure to follow the instructions regarding your track saw track cutting guide. Mine has a black plastic guide on each side of the track that had to be ripped with the first cut for it to be operational. After that first rip it then lines up perfectly where it's placed on the cutting surface. So if yours is similar then you would need to place the track closer to the 8' edge on your first rip, leaving about 1/4" or so to rip again after it's calibrated. And don't forget that both sides of the track will need to be calibrated. I have two different tracks, a long one for 8'+ and a short one for 4'+. Your measurement marks with a tape measure will determine how accurate your cuts will be once the tracks are calibrated. So use a sharp pencil or pen and make a short accurate mark on each end of the sheet that the track will line up with.

A 4' square is always nice to have for general carpentry work/drywall work too. Worth the investment if will be doing any work in the future for sure but not needed at all with a track saw and shouldn't be used really since a measurement on each end of the cut is what is needed to line the track up.

And just a suggestion. An extra sheet of wood to use as a base or cutting surface will make your life much much easier. I have a table that is the size of a full sheet that I just replace the cutting sheet on every now and then. But a table isn't necessary. You can lay the cutting sheet on the floor or on a few saw horses and still get by just fine. Just make sure to set the plunge on the saw to barely go into the cutting sheet. OSB or any type of wood will work as long as it's pretty close to the same size as your working pieces.

There's a sheet of plywood that's been on the side of the house for a few years. And I bought some sawhorse brackets. Planned on using that as my work surface. Maybe add a sheet of foam in there if needed.

Waiting on funds for wood, router and clamps. I can't imagine it will take too long. Got a chance to play with the track saw using some scrap plywood. It gave me confidence I'll be able to make nice straight accurate cuts.

Picked up a router and clamps. Now I need a jasper circle jig, and some router bits. Basically done with tools now, wood is next!

Ordered the jig and router bits. I'll get the wood in here soon. That part is a pain in the ass for me though, I have no truck. I'll have to get my mother in law to help me out, and get help with the kids, but either way I'll get it done pretty soon.

You could have HD or other cut the sizes down. Or can you not fit a 48x48" piece in your car?

Just got back from my local ace hardware. Picked up the 4 sheets of mdf they had, and a piece of foam insulation to cut on top of. I need to get an adapter to use the dust port on my saw, but I'll be started on the first sub shortly. I'll make sure to take some pics of my dirty ass garage along the way!

If it ain't dirty now it soon will be. I spent a couple of hours today sanding and routing MDF. .. Should have worn a respirator.

Hm. The foam insulation is a good idea. How big and what thickness did you get?
