With what I had at hand, works a treat.

I managed to spray a couple of coats of finish on the external base boxes, the colour is darker that I expected so I am holding off putting more coats on until I'm ready to put them together, by them I'll have decided whether to change the colour or stick with what I’ve got. The looks black until you put them beside the inner boxes which are black, then you can see the slight gold in them. The metallic gold sparkles beautifully in the sun, but they won't be spending anytime in the sun :).

I planed all of the legs ready for routing & managed to get two done, the second leg took 65min just to do the routing, without stopping. The first one took longer! Only six & a half hours of routing
to go :eek:Then they will need lots of careful sanding, 1% inspiration, 99% perspiration.

PS: If you look at the bottom 2 holes of the box you will see where a wasp made a home for some eggs while they where drying, needless to say they wont be hatching.

Still plugging away, the legs are sanded & have a coat of oil finish on them, I intend on putting a couple of coats on before I fit them to the boxes.

I have changed the finish from a brush on lacquer, to the wipe on oil finish because I wasn't happy with the lacquer finish I had already put on the MEN. It's a finish I've used many times before but this time it wasn't doing it for me. This of course means I have to remove the lacquer I have already applied, yeah I know "my own worst enemy".

I think I have already mentioned I wasn't completely happy with (is this man ever happy) the colour of the boxes, too dark & not enough sparkle, well now I have a small tin full of Gold Pearl to play with, this could really stuff things up :)

I've ordered some 1/4" brass coach bolts to screw into the bottom of the legs to act as adjustable feet.

Well a little bit of Gold Pearl goes a LONG way. Initially I put 10ml in with 150ml of colour & it was way too much, I ended up using 5ml & I'll have to say the colour is just about perfect. Originally I wasn't going to put clear coat over the colour but it marks really easily, I think it has something to do with the texture as well. Does anyone know if you can put water based acrylic over automotive acrylic 1K lacquer?

If I had my time over I would do several things differently, wouldn't we all!. First I would have stayed with the original plan & used a metal bracket to support the bodies as was the original plan. I went away from the metal bracket as I would not have been able to make them myself at a higher enough quality. In retrospect I should have forked out the money & paid a professional to make them for me, as going to the carbon fibre alternative (which works just fine) has added an enormous amount of work. I would not do the box within a box as it has also added an enormous amount of work, it was done to keep the box size to an absolute minimum size. And last I would probably have made the base for the bodies out of stone (marble, granite?) and isolated the body from the base using some sort of dampener and not actually fixed the bodies to the box, just relied on the weight of the stone.

If I hadn't done everything twice it would have speeded thing up as well, some things I've done several times

I am using 1/4" brass coach bolts as adjustable legs for base of each timber leg.

I'll have to say I'm just about over it, but there is light appearing at the end of the tunnel now.

I am using a protection cap for the tweeters & have stolen 56's idea re the perspex brackets to hold them, I should have known anything 56 did would take forever to do, I don't think they will be quite the quality of 56's either.

Took all day to get the capacitor holders finished and I had help!

The gold bayonet plugs are 5mm & come from the model car hobby fraternity, the socket will be glued into the plexiglass holder & the tweeter + will be plugged in, in series with the speaker terminal.

The board the capacitor holder is sitting on is my test spray piece, I sprayed a coat of Mirotone Satin water based lacquer over the automotive acrylic colour & it appears to be fine, it really helps with the metallic finish shine when in the sun, I'll have to get a couple of well placed halogen spotlights for effect :)

I beat you can't guess what the little hexagon pieces of wood are for.

Thanks for the encouragement, it helps when the going get toughs and when I'm disappearing up my a#se :D

You'll notice Ive only showed you one of the capacitor holders:rolleyes:

The hexagonal pieces of wood are to cover up the holes at the top of each leg.

Have a great New Year
 
Thanks guy's, in Australia it's " Blow warm air up you ar#e" I think I like the feather better :D

It's been a very hard day at the office! After I put the primer (blue paint) on, and before I put the finish coat on the boxes I made sure they would fit together, guess what, they don't want to go together even though there is no extra paint where they join. I spent hours getting the bass driver box into one of the outer boxes. I assume it's weather related, it's a lot hotter & more humid than when I did them originally. In the end I put the bass box in front of the air conditioner for an hour or so & that did the trick, of course there is the possibility the box may expand & break the outer box:eek:.

Anyway tomorrows another day.

Number 2 is almost done, I still have to make the grill covers & small covers for where the wires are terminated on the mid & tweeter.

If you look closely you'll see a couple of extra holes that I mistakenly drilled long ago, still haven't decided what to do about them.
