Hi Y'all,

I have used T-nuts for a long time, and if you watch what you're doing they are fine; but, so called hurricane nuts are probably better, e.g.: http://www.parts-express.com/pe/show...umber=081-1084, and the barbed body inserts are better yet: http://www.parts-express.com/pe/show...umber=081-1094. The hurricane nuts,and barbed inserts need well cut clean holes, the T-nuts are a little more forgiving, but have a tendency to fall out unless expoxied in place.

In the LAB12 TH thread, Post #25/27(corrected link) layertone gives a link to self-tapping, threaded inserts (in my opinion they are the best):

Lab12 - Tapped Horn -

And make certain you get the blue Loctite #242, or you'll be in trouble.

Regards,

I would hate to use locktite wtih a wood tee nut, it could "strip"..Now that would be a mess, never get that out.

Yes I did think of that, but never seal wood before glue (in case something moves)

btw, How flat of a response will it have? How low will it go?

Would really like to see it finished also!! But that said I wish I never saw the first set of Pics.

[becuase I want one]

hi all,
The blue paint is there so when I take it back apart(I make a mockup assembly first minimal screws) and then spray paint the edges,then you can drill 2 sides at once and have them square and in place and make sure the screw hits the middle of the board,I also use a magic marker to show screw lines across the top of angled boards for pre drill/counter sinking,
I found out it will be best to start reassembly from the inside out, my power drill won't fit in the smaller spaces outherwise,
Thanks Epa ,I got sawdust and a bunch of long skinny triangles,They might work as gussets,lol
Cheers!
NS

Here's my contribution...

I hope mine live up to all the others that have been put up recently

I should get some better pics as I build. I got a CM140 SPL meter for my measurements, so I can throw up those once this one is done and I can take it down to the field.

This sub is 1 of 4 Still have to add cabinet hardware and paint, should be able to do some testing next week

Is it ok just to attach the driver with wood screws? If I have to go back to home depot it means purchase orders and purchase orders and purchase orders and purchase orders...

I must say that the paperwork associated with doing all of this for the school is very annoying, I am used to just doing my own thing and just buying things when I need them
