Re: Nubie's Build - The Copper Project

Had to stop to work on kid's school project. For those who have grade school kids, had to work on Flat Stanley Project.

Ahh yes. Flat Stanley tries sailing with no sails.

The roundovers on the Cooper's baffle realy make the design pop. Looking good. Hard to believe you did this with just a battery saw. Well done.

Re: Nubie's Build - The Copper Project

Perhaps you are already planning to do this, but just in case... before you glue the baffles on: drill the holes for the woofer (all the way through, so you can see where they come out the back) and chamfer the space between the holes. A big 45 degree chamfer bit would be good.

Hopefully somebody will bring a pair of these to INDIYana next April.

...8. Wear ear and eye protection at all times (especially when wife comes into garage and complains of dust everywhere)...

Is this to filter out unwanted "noise" and to protect eyes from thrown objects? ;)

+1 on #6. I hate the wandering tape measure. And all the rest are spot on. I would like to add #10-

If you only have one of something left, and need it, you will render it useless in some form or fashion.

Christopher's Rule #1 Of Tools (for the absent minded and messy among us):

Get three of everything, then, by the time the next two are lost you will have found the first one that got lost (I think I have about six tape measures. I know I will never get a full count of exactly how many I have, because there will always be at least a couple that are in temporarily unknown locations...)

Also, if you're going to be building more speakers (and you can't afford to just buy every cool tool that catches your eye) it's worth it to make your own router table. The one piece I had to buy (besides the router) was a "blank" 1/4" acrylic plate. I got that at a "wood show"/tool show and it came with a nice little hardboard template which made it easy for me make the cutout on the scrap piece of Formica countertop I found discarded. My next step is to make the two-piece fence...

I was planning on doing that. Marty recommend three router bits, the 1/4 straight, 3/4 rounding, chamfer bit.

Yes, the wife always nags when it comes to loud noise and sawdust!

I think I have a total of 6 throughout the house

I was planning to build my own as you suggested with a piece of acrylic and build it into my workbench, but I'm eyeing a table saw as my next purchase. Any suggestions? need to be portable so I can put it away. (Dewalt?)

Can't wait to finish these and start listening to them!! (I'm so impatient!)


Thanks for all the comments!!!

OT: here's one of Flat Stanley at the Rose Bowl!

My tool set is pretty similar to yours - although the results have not been
as good :o -- for some reason I got the table saw bug recently, and have been thinking about buying a Dewalt 745:

The rip max is 16 1/2, but I really don't want to try to cut a large sheet on a table saw anyways - I can use my sawboard to cut it slighly oversize, then do final trim on the table saw. It has a rack and pinion fence that seems fairly accurate to me.

Awesome! That's the exact one I was looking at, via Amazon!! I like the idea of rack and pinion, and there were alot of good comments about the quality.

But then I do make a living with my fingers and hands, and thus losing one is not an option, so my wife wants me to get a Sawstop. But quite a bit of difference in price, and no where to put it.

Re: Nubie's Build - The Copper Project

I'm curious, what is it that you do for a living?

None of us want to lose a digit, but "not an option" has me intrigued...

The shop on base has 2 of those sawstops, they are beautiful machines. you have to replace the device or w/e it is, but @ $250 per... I'd say it's a fair price to pay if you did ever have a slip, especially if you work with your hands. I'm a driver, and I'm military, so I'll be ok with my $130 Skil tablesaw ;)

Re: Nubie's Build - The Copper Project

I had the Bosch portable saw and was happy with it, until it got stolen.

The Bosch comes out on top in some reviews where they compare different brands. Other people have been happy with the Rigid (wasn't out yet back when I got my Bosch).

I decided my next saw would be a little heavier and went with the General International contractor's saw with the cast iron top, left tilt. It has a more powerful motor than most in it's price range, a decent fence, and 2-phase 240 power which was easier to deal with than three phase.

The Bosch job site saw at Lowes looks very good, but it's $599.
For $350, I think the Dewalt is a best buy. Checked out the rack and pinion fence at the store - very smooth and precise adjustments.

Re: Nubie's Build - The Copper Project

I've decided on the Dewalt for my next table saw! I had to consider my limited work/storage space and love the rack and pinion. Waiting for Amazon to dip down a price a bit more.

As for my profession, I'm a HAND MODEL :D







no, I'm in the medical profession and work with really small stuff ;)

Installed the dowels to keep polyfill 13" up from bottom.


Finished up my baffle repair, starting to look good.


Installed all components onto board, need to connect wires and solder everything together. Anyone see anything wrong with this topography?


6oz of polyfill installed, need to buy some more.




Now my dilemma, I want binding posts near the bottom. I have purchased these:



unfortunately If I install them now and glue up the cabinets I will no longer have access to them from the inside and when I go to veneer the back it would be difficult to veneer around them.

1. Should I just install the binding posts up high where I can access them from the removable front baffle?
2. install them low for now and later cut them out and install this?



Yes, I am impatient and want to get these running to see how they sound before completing the finish!!

Been researching veneer techniques, boy is it all confusing! Any suggestions?

Thanks

Re: Nubie's Build - The Copper Project

For my first veneer project (very soon) I am going to use Pressure Sensitive Adhesive veneer. A little more expensive, but I won't have to deal with oozing glue from iron-on and big fumes from contact cement.
http://www.tapeease.com/PSA_veneer_sheets.htm

Just have to purchase enough, line it up right, and trim it without tearouts and/or chipping. That's enough for me to worry about.

Re: Nubie's Build - The Copper Project

First off the speakers are looking real good. As for the crossovers they look alright to me, the only thing I would suggest is to move the small inductor closer to the white resistor, the further away from the other inductor the better.
On the binding post, if the back is already glued go ahead and veneer and trim it, then mount binding post and run wires to crossover. I would probably mount the crossovers to at this point.
One last tip would be to make some bench cookies, if you want them to look similar to these. http://www.rockler.com/product.cfm?p...bench%20cookie
Cut some scrap mdf into 3-inch diameter pieces and glue either pieces of a router mat to them or get some tacky mesh drawer liner http://www.amazon.com/Grip--Shelf-Dr...6144567&sr=8-1
and glue it to the top and bottom. You can also glue 2 or 3 discs together to give you the height to get clamps under your work piece. These will keep your veneer from getting scratched or gouged when attaching the front baffle.

No, no, no. We don't mock 'The Marty'. Instead we do this:

Looking good! Yup, when you fire these up you will be very pleased. Anyone at Iowa DIY 2009 will tell you that Marty did a marvelous job on these, even with that cheese handicap of his. The low end was really amazing from such a small woofer and the voicing was perfect.

Please learn this simple lesson, Mr. Wolfie.

Thank you,

Re: Nubie's Build - The Copper Project

you don't need binding posts just to play them before they're finished. Drill a small pair of holes with no space between them just large enough to push through speaker wire - temp. solution to getting the signal into the box without running the wire through the vent...
