Ant to build Mikasa/Saburo but.....
 
I'm having difficulties finding a local supplier that carries BB that's larger that 5' x 5'. Am I SOL? I called a few distro and they don't seem to carry it. If anybody in Toronto/GTA knows where to get it, please let me know...I watched a youtube on the Saburo and I'm liking what it can do :D

Well, since the side wall panels on these designs aren't carrying a lot of vertical stress load, you could always laminate your own panels from 2 staggered layers of thinner material.

But by the time you factor the material and time factor to do that properly, the easier answer would be to source 4x8 sheets of a product that is locally referred to as "europly" - a brand name that is often taken as a generic is Appleply. The last time I priced some, the price was more than double that of the shop-grade baltic birch, and frankly since I have enough projects to keep me occupied, that helped the decision making quite a bit. :angel:

I haven't sketched out a full cut list for the Saburos, but you would need 2 full sheets for the side panels, and possibly into a third (could be cheaper BB) to complete the internal parts

hmm if i had to go that route I'd probably do 1/2" mdf for the exterior and line the inside with 1/4" ply. Ideally I'd like to use a full sheet of ply as I plan to stain it. I'm still contemplating building the mikasa vs saburos. There's also the fonken that I need to build ;)

Were you going to edge-band the plywood with some solid wood? If so, you could incorporate a strip of the solid into your design. I'm thinking that you'd have the outer layer's joint about the middle; in between the upper and lower halves you would incorporate an accent stripe of solid wood the same thickness as the outer layer of plywood.. It would probably look good if you made it somewhat diagonal.

Just a thought, but could be nice.

Regards.

Hi,
Did you try Central Fairbanks ?
I know they have BB in 5' x 5'.

You're a life saver. These guys carry 4x8 BB and they can cut them to spec! bout 68 bucks per sheet for 3/4".

I'm considering going with a 45 mitre joint and expose the edges. I'd think the internal pieces would be strong enough to hold the sides together?

I'd be inclined to leave that for a simpler project ( i.e. one without all the internal parts) - deadly accuracy of cutting is imperative, and assembly would be much more complicated

I guess that's reason why most of the designs have a fixed width dimension?

Also, I was looking at the Saburo and Sachiko's dimension. They seem to be pretty much identical besides the baffle, and spacing in between the two horns. I'm assuming that dimension for the internal pieces dimension are exactly identical (again, besides the width).

Well, yes, with all the internal parts of the same width, the cutting plan and assembly is much easier - and while it's not fair to underestimate the joinery skills of any potential builder, the manner in which your question was posed suggested a degree of trepidation.

Mitre folding a simple rectangular box with a limited number of internal panels isn't all that difficult, however these designs are a bit more complicated than that, and it would be unfortunate to get frustrated by getting in too deep in terms of assembly skills.

Actually, there is a difference of 7mm in the height of driver chamber, throat aperture, horn mouth spacing and overall height.

Situated between the 2 designs, is the Hiro - for FE166E/SR and FE168E Sigma.

Thanks from me as well! Does Central Fairbank charge for cutting or is that included in the price?

I know they're cheaper than Home Depot on many items, but did you confirm with them that it's BB and not just Baltic Ply, because that's about what a 3/4" sheet of ply will cost you at HD.
