The only pair of Model 19s I have seen down here...

ED!
That solves a mystery for me of long standing. Building head cabinets for my amps, I've been baffled on how to insert the front board face without using cleats.....which does a lousy job anyway.

This folding business allows me to use biscuits to join everything correctly. Wow! Thanks.

Using a couple of coats of lacquer sanding sealer on the inside not good enough? Poly? I know that in experimental aircraft building, epoxy is used for bonding and it literally comes apart when exposed to moisture. So, the FAA accepts encapsulation with poly or epoxy varnish. The only approved aircraft glues are aerolite, weldwood, and resourcinol. Molecular bonds. Jeepers is this a speaker forum? Moving kinda far afield here.

I have an old Freud biscuit jointer that works, but that's all I can say about it.

I've got an Amish blade in the saw now, but intend to invest in a Forrest before I start any real projects. How you like this:

Boice Crane. As near as I can tell, between 1932 and 1935. 7.25 under the guides. 14" wheels. Those blade covers are Cast Aluminum! How they survived all these years is anybody's guess. Babbitt bearings.

You should see my wood lathes. I have no use for them, in fact if you'll pick them up you can have them, but they are Porter. A 16" and a 24". Came out of Paramount Studios workshop. In case you want to play Cecil B DeMille and make some Grecian columns. Feel like turning a hot tub? They are timber framed so the length is unlimited. One knife bar guide is 6' long. Line shaft operated with all that hardware. I'd convert them over to three phase with a variable frequency drive.

I think you need them. ;o)

Cool bandsaw. I have a couple of Walker Turners and a 36" Northfield. The Walker Turners are sweet little saws, but are pretty mundane looking. I've used only Forrest blades for 15 years. Ask for Tony, extension 313, mention me, and tell him that you love Led Zeppelin - you'll probably get free blades! I also feel that Forrest does by far the best sharpening job, although they are more expensive.

I know about the FAA's dislike of epoxy, and it's always puzzled me. I started out as a custom boat builder and there are a lot of old cold molded boats still out there. These days we build custom cabinetry and carbon fiber race car parts, and use epoxy every day. I would have considered epoxy ideal for our folded cabinet project, but it leaves a thick glue line where it saturates the wood - giving the illusion of an open joint.

My experience with balanced laminates is that you can never tell what is going to happen, and the cost of failure far outweighs the cost of caution for us. I've seen MDF veneered on one side cup like a cereal bowl, and other MDF with an unbalanced laminate stay dead flat for years. Encapsulation certainly helps, but wood expands and contracts with temperature as well as humidity, and about 9 times as much across the grain as with the length. How could 1/40th of an inch thick veneer move a 3/4" thick piece of MDF? Got me, but it does.

My point is that if I were putting 40, or 400! hours into a pair of speakers for myself, I'd throw an extra hour or two into veneering, and ideally finishing, the the inside of the box, particularly if the design had large panels without internal support.

Thanks again Ed. I'll do it your way. I'm going to try re-saw with the bandsaw. It will be fitted with a VFD and a 3 phase 1/2 horse motor. I have my doubts about getting a decent cut but it's worth a try. I'm not sure yet how wide the wheels are. It's setting at my Brother in Laws house in San Luis Obispo. About 7 hours away. I bought it out of an engineering lab at Cal Poly. I've seen it and it's beautiful but I didn't have the pickup with me that day.

I have about 500 BF of aircraft spar lumber that I bought for a project and never used. It's mostly 5/4. I intend to experiment with spruce baffles for guitar cabinets. I know I know, but this isn't Hi-Fi. Guitar cabs dance to a different drummer. Last time I made a cut on that lumber it was case hardened. That was 13 years ago.

I think 3k is an excellent deal if they are in good working order.

Money is not an issue with me when it comes to audio equipment. To date I have never heard anything better. I have seen and heard PLENTY of systems that cost a hell of a lot more than 3k and they simply wont hold a match to the Altecs.

Not everyone will agree with me and I dont care. My ears love them above all.

The day I find something better I will have them but for now.... Its Altec.

I must have got the same set of ears you did
