when screwing or nailing the boards together is it normal for it to split a little?

any way the pics here are the pics of the finished box. 1 cube @32htz

it is for 2 8"s that i bought off of brtnboarder notin spectacular. just for use in my room on a old receiver. right now i have it hooked up to a crunch running 140wx2 running off of a deka 60

pre-drill and no nails. wood should not split

I always use a 1/16 drill bit to pre-drill with, and then follow it up with something to countersink the screw heads. Without a doubt the best kind of nail/screw I have ever used are 1.25" coarse thread drywall screws. The thread is spaced out much further and really grips the MDF well, as opposed to other screws that tend to shred the mdf apart after screwing and unscrewing several times...then you end up stripping the hole.

just like everyone else stated, you must pre-drill. And I agree on the 1.25 corse thread drywall fasteners.

I don't need to :fyi: I never have my MDF split when I predrill with a 1/16 bit.

What size do you normally use, 1/8?

I agree per-drill is the best to avoid this.I also put a dab of wood glue in the hole just prior to screwing it down.This will squeeze out through any little hairline cracks that maybe in the wood.

i was just wondering cause i pre-drilled and then when i put the screws in it split a little bit

i predrilled with 3/32 and used i think it was #6 sheet metal screws. i used 3/4 mdf

i think the screws were a little long though.

pics will be in first post.

I used to use 2-2.5" screws when I first started doing boxes and found out shortly that it was just a hassle and unnecessary to use screws that long. The 1.25" coarse thread drywall screws are just the right length and have an insane amount of grip.

pre-drill and no nails. wood should not split

It still can if the screws are too close to an edge. Pre-drilling does not eliminate splitting and only slightly reduces the risk.

If you really want to avoid splitting, you should really try to keep as few screws or nails per side as possible. If I'm using screws, I use 1 or 2 per panel up to about 30" long or so and then I would use about 3. Also make sure to leave about 5-6" before the edge of the wood as that's an easy place to split the wood. Try not to use a screw or nail that is too long either. I stick with 1 1/8" screws as they will pull the wood tight enough for the wood glue to bond well and that's all you need them for.

IMO you can't go wrong with the 1 1/4 drywall screw.I have built many boxes over the years and learned from my mistakes.Supplies I use are TBII,1 1/4 coarse thread drywall screw,and some 1 3/16 brads to hold things in place.

I use brand nails on my smaller boxes and it works fine, you just have to make sure your cuts are spot-on since brad nails don't **** up small gaps like screws do. But with building 5' long boxes that are going to house a couple of 18's each, I need my screws to make sure everything is sealed especially well and never going to leak air.

Exacaly, they are just used to hold the wood until the glue dries.This is the main fastener in the box building process.

You always have to predrill if you're going to screw something into MDF...not doing so (even just a little) is just asking for the MDF to split. Also, no screw is going to mount flush enough for my tastes...I actually like the screw head to be about 1/8" lower than the MDF so I don't injure myself or my truck when installing/moving the box around.

i dont use nails or anything other than clue. heres what i do.

i bought those pony 90 degree clamps. i clamp one end on one board, then line up the other piece on the other side of the clamp so that the edge of the twoo meet flush. i dont tighten that side down, put glue on the clamped down piece then lower the 2nd board on it using the pony clamps. once it aligned right (always is using my way) i attach 4 bar clamps and remove the ponys.

tada perfect 90degree board tight and clamped already to go.

Let it dry

Initially, that was my though as well, but I looked at those screws, and they are made to use in MDF without predrilling. So until I would use them, I really cant say if they will split the wood or not.

The only bad thing with doing it like this, is it takes a lot longer. You have to clap up pieces at a time, wait for the glue to cure, then do it again. It does make for a nice finish, especially if leaving it bare though.

no.. no predrilling at ALL. i actully drilled 5 or 6 in the side of a piece of MDF when i bought then becasue I thought there claim was BS. sure as **** I drilled the WHOLE crew in their, and the screw actully went about 1/4 inch in the wood, the only thing that split the wood was that the phillips bit that I was useing.

no.. no predrilling at ALL. i actully drilled 5 or 6 in the side of a piece of MDF when i bought then becasue I thought there claim was BS. sure as **** I drilled the WHOLE crew in their, and the screw actully went about 1/4 inch in the wood, the only thing that split the wood was that the phillips bit that I was useing.
Trust me try these screws, you will not bew disapointed.

No pre drilling AT ALL
If wanted you can make the screw go as much or as little into the wood as you would like.

But did you do it within 3" of the corner of the MDF? I can screw all day long in the middle of a piece, but the corner is where you're going to see some easy splitting. Unless the screws are really skinny, I doubt that I can use them close to corners without predrilling.

i dont use nails or anything other than clue. heres what i do.

i bought those pony 90 degree clamps. i clamp one end on one board, then line up the other piece on the other side of the clamp so that the edge of the twoo meet flush. i dont tighten that side down, put glue on the clamped down piece then lower the 2nd board on it using the pony clamps. once it aligned right (always is using my way) i attach 4 bar clamps and remove the ponys.

tada perfect 90degree board tight and clamped already to go.

Let it dry

I say good day to all you screw users.

Like bjfish said, just takes too much time that way(for me at least)...using screws I can assemble a box while the glue is still drying and not have to wait at all. If I had the time and patience to spend all day long waiting for glue to dry, I'd do it...but obviously I don't :D

Check into those screws. They seem pretty cool. I dont think I would use them, because you always run the risk to drilling them in crooked and having them break out the side of a panel. Its all personal preference though, but to me, it wouldnt be worth the extra cost. Im pretty quick predrilling...

No I did it on the side..... where there is only 3/4" ;)

and yes the screws are skinny, it looks like a regular screw with a thinner shaft. It is also self taping, and under the head of the screw are 4 claws?(for lack of better words) that help the head flush or deep mount it want.. I will post some pics tommorow afternoon so you can get a better idea. I was so skeptial as well

Obviously on the side...I meant within 3" of the corner as well, since drilling on the side of MDF, near a corner, is an easy way to split it.

propimp's claim is 100% correct. i used these spax screws for an amprack i built today since i didnt wanna wait for glue to dry.

i was using 1/2 mdf and it only split on 1 of the screws out of 16 and it was only because i didnt center the screw in the 1/2 mdf sheet completlely centered.

Comes with the special drill bit to use with them. they have teeth on the threads of the screw that grab and bite into the wood as u screw. thin, and best part is that the screws mount flush or can be inset. i was able to get each screw 1/8 inch down everytime and there was more room than that if i wanted.

Love these screws, however i still am not going to use screws on my boxes cause i love the durability im getting with just using glue. if i sacrafice time, so be it.

thanks, I found these screws about a month ago and have been tryingto let people know how easy they are to work with. But brad nailers pwn screws IMO. But I dont have a brad nailer.
