Zia, I haven't started breaking in my drivers yet. I'm waiting for my amplifier to come back from the reapair shop. It's a Pioneer SA-7800. It had zero output from either channel and I couldn't figure it out on my own. I've been without a sound system at all for over 2 months now and I'm very very ready to get my equipment back.As for the internal bracing. I drew the bracing in AutoCAD and sent it to my CNC router to cut out. So all-in-all, the bracing was fairly easy. All I had to do was slap a piece of plywood on the table and watch it cut. My cut out as well as flush cut for the speaker was also done on my CNC. When using the CNC you don't have to worry about uneven cuts like on a table saw, or the danger of using one. I have a slight advantage in production due to this. If I really wanted to, I could do a Dado'ed construction (or non) of this Pensil or any Pensil and pump out about 100 pairs per 8 hour day with this machine.

careful dude, you could be asking for trouble - just keep in mind to cut for friends & forum members for local pick-up only - packing for safe transit and freight charges could give everyone sticker shock

Hi SteveZ, Guys,

Looks like there's a problem with the system or server. I think Jason (admin) will be on to it as I type. I'll ask him if there's a way for images to be attached to your existing posts.

Steve, maybe we have to delete this thread and start again. Let's see what Jason suggests to fix.

Save all your pics guys, I'm confident we can get them on soon.

Cheers

Mark.

Sounds good Mark. If I need to delete this thread and start a new one that's no problem at all. I ended up finishing the cabinets this afternoon. Total cutout and build time was exactly 2 hours. Not too bad. I'll be ordering some veneer tomorrow, perhaps ribbon striped mahogany or some variant of maple (curly, burly, birds-eye). Stay tuned guys, we'll get the photo situation worked out and I'll be posting the build progress soon.

Hahaha it's alright. I don't plan on reproducing these cabinets to sell. I was just stating the machine capabilities. If anything I'd only build a pair for my father, and maybe my brother but that's about it. Though I will say this, if Mark or someone else who has designed enclosures would want me to mass produce some cabinets or even offer flat packs I'd be more than willing to work a deal.

Looks like the problem has been resolved. Here are the first pictures of the raw material after being cut out. I'll upload a couple more when I get some more time.

Nice work Steve - particularly on the grain alignment on fronts & back - how much juggling did it take to get yield above 60%

With our commercial CADCAM software ( CutPlanner), it's more of a fight to override the yield optimization for any grained material than to just hand bomb the layout for grain /pattern matching. Of course if post veneering, you've just transferred that issue to another material .


The ribbon grained mahogany with natural lacquer or conversion varnish would make for a stunning look on these - that's likely what I'll be doing with an upcoming FH32 build in the next few weeks. With any luck, some pictures of the build this time.

I actually didn't bother with alignment of the grain. Though it did take a few minutes to place by hand all of the parts on the sheet correctly. Here are a few more pics. I'll upload the completed photos in a couple of hours.
