I just spent an hour going through the pieces of wood and the drawings Brett sent me this morning with all measurements converted to mm (thanks!), test assembling a couple bits and understanding how it fits together. I have to say, they did a great job with the designing and cutting, accuracy looks as close to perfect as I can measure.
The grills look really great and that's 90% of what I'll see when listening.
Here are pics of the assembly for reference:


The magnets for the grills need gluing in place, I think I'll use construction glue to hold them in, probably will use titebond II, ordering some tonight.
Don't have many clamps so may get a cabinet maker friend to help glue them.
The grills for the front and rear of the subs are magnetic, the grill in front of the coaxial is plastic push in snap lock lug things, not sure why no magnets there but they do look good quality.
Yes I got bits for the amp boxes too

Just 5 pieces and the amp screws into the edges of the box.
PMs sent re the cost. Shipping was expensive to Australia but nothing can be done about that, Brett got me the best price.
Not sure if I should post the cost here but happy to answer any PMs with all info

It was certainly
very competitive with other prices mentioned, especially considering it's baltic birch.
All up with all the shipping and then deciding to upgrade the coax drivers and crossovers to Super V spec , this is going to be an expensive project but great value if they look and sound as good as I think they will.
Have a custom integrated Dodd amp coming too

Thanks for the tips on finishing, I think I'll have these for a loooong time so want to get a fimish I will be happy with for good.
Brett sent a bunch of scraps for me to test differet finishes on.
I'm going to take my time deciding on a finish and make lots of samples first, don't want to rush a half baked finish.
Hank and WGH, I really appreciate the input and think I'll need a lot more before this is done!
That 1-2-3 and wax finish sounds like what was done on the turntable which looks beuatiful and very smooth, satin, almost high gloss but not very protective, so long term maybe a poly will be better.
I also like the idea of a thick, very glossy, hard and mirror smooth top coat on them so anything will wipe off for years to come and still look good.
Would a stain and then lots of coats poly work well?
That 1-2-3 finish may not be what's done to the TT though, could be danish oil or something.
I will certainly do a sample of the 1-2-3 anyway.
Another point is color, can I use a colored varnish with the 1-2-3 method?
I may like some red/orange color to match the cocobolo on my turntable, in first post.
Any pics of the different finishes, anything to read or samples I can buy would be much appreciated!
