1st speaker build (final pics added)

*******FINALLY FINISHED PICTURES ADDED IN POST # 44****************To preface the following descriptions, I am adept at using basic hand tools, but am by no means any type of accomplished wood worker. I have only basic tools, drill, hammer, jig saw, chop saw. No routers, table saws or other larger tools. So some of the work was handled by, or with the help of a couple non AK friends.

I've purchased some speaker components from fellow AKer GordonW which arrived a couple weeks ago. They consist of custom woofers built by Gordon, some Magnavox mid horns and a modern supertweeter in addition custom crossover that he also built up.

My idea was for him to build them up according to my vague instructions and then let me know what size box I needed to build to match what he had built up. So they are going in to some custiom built ported boxes approx 3.5 cu.ft. I'm using oak plywood but the are going to be a style similar to some of the older furniture type speakers with integrated legs and a the top will have a bit of overhang.

I presently have the boxes semi-assembled. still need to finish up the leg assemblies, permantly attach the fronts and backs (temporary for now) and do some sanding, staining and final finishing.

Since I didn't have the proper saws and or router I took the dimensions to a friend and had all of the panels cut to my specs. I also had the holes cut for the woofers and routed to be flush mounted. Everything else on the cabs has been or will be completed with my hands and my minor arsenal of tools. I cut the crossover/speaker terminal hole and mid horn hole with a jig saw and used hole saws for the tweeter and vent port holes.

After some testing, I'm hitting them with a walnut stain first which really brings out the darker part of the grain, then another coat of gunstock stain which adds a bit of red. I haven't decided if I'm going to finish up with danish oil or a wipe on poly.

Hopefully I'll be able to put up some pics in the next couple days and show my progress. Any suggestions are appreciated.

BTW, pray for me to complete this project without destroying any of the components, the cabs, my shop or any of my fingers.:D

A thought for you

I'd recommend making the backs removable. You may need to tune, replace components, etc.

Yes, it will be removable for now. Will be screwed on and with a gasket. I think I will ultimately glue it in place once I'm sure I'm good on everything. Then if anything happens, work will have to take place through the woofer hole. Thanks for the suggestion.
 
OK, so I'm gaining some ground. I snapped a few pics as promised and they are below. Pics aren't the greatest, I'll get some good ones once I get them finished.

Pic one is the boxes during fabrication. 31.5 x 20 x 14 inches or so.

Pic 2 is of the backs after sanding and getting some stain, no final finish yet.

Pic 3 and 4 are pics of the baffles which are 3/4 birch and 3/4 oak plywoods back to back, glued and screwed.
Pic 5 is the baffle in place on the box (with no back) baffle is not pushed all the way in place though.

More pics to follow. There are a few things I've learned as I've gone along, Ill try and put them together is some type of orderly manner later.

Here are a couple more pics from today.

1 is of the rear baffle, lower hole is for the 4" port (inside diameter) yet to be installed and the upper is for the speaker terminals, mid horn control and crossover pad. The port hole is actually 4.5 inches and the port tube will be painted black and is a snug fit so it should work out well.
2 is of my wonderful young helper standing next to speaker #1 after some staining. The back is not in place. The legs have not been attached yet either, it's just doing a balancing act. The top, although I did put a coat of stain on it, will be covered with another pc of 3/4 oak play that will be trimmed with some 3/4 inch mitered oak boards to give it an insert effect.

I'll have to get some better pics of the legs as they turned out pretty good, I beveled all four sides of the bottom and they will then get some spikes inserted.

So far so good. I'll be adding another coat of Gunstock color stain which will add just a hint of red so it will look the same as the backs. Still haven't decided on the wipe on poly or danish oil, any suggestions?

Nice work. Looks like you've done this before.:thmbsp:

Can't really help with your finishing questions, but I would think the wipe on poly will be less work in the end.

OK, no pics tonite, but made some more progress. I decided on the Danish Oil finish, I can always add poly over it if I like. Put a couple coats on the backs to see how they look and will look at them again in the morning, but I think its a keeper. I finished up putting the legs on speaker #1 and also added the top with the insert. It turned out good IMHO, but when I'm out in some better light all bets are off. I'll give it the Danish Oil treatment tomorrow and all that will be left is the leg spikes (which I may save until everything else is complete). Then I can start on the port, bracing and internals.

Oh, I have the legs for speaker #2 semi complete. All the glueing is completed but they need to be cut to length. Then go through the steps I've completed on the first one. I've been trying to stay a few steps ahead on speaker 1 so if I've messed up, hopefully I only need to rebuild one of them.

My expectations were low when I started so right now I feel like an over achiever. :yes: This project has stoked my creative fire though, I may have to build another pair in the future.
 
OK, one is fully operational. Still needs the floor spikes and some minor tuning tweaks, but all is well in the man cave.

Attached are some pics.
1 is finished (have a cold one)
2 pic of the inlaid top
3 pic of the beveled leg, not too visible, but a neat touch I thought. Will show up a bit better once I install the spikes.
4 & 5 are pics of the bracing and some insulation on 1 wall, I did all walls except the front baffle.

More pics to follow in next post.

A few more pics of speaker one enjoying the sunshine.
1 is a side profile shot
2 rear baffle with crossover and frequency control and port tube installed
3 backside of rear baffle, I'm still working on the port position, I'm afraid it may be too close to the corner. The feet belong to my favorite helper who hung out with me in the man cave all day.

All in all, it's been a great success IMHO. I don't have a joiner/'planer, many tools that would make things easier and more precise. With some patience (which I'm not the best at) and planning, I was able to get good results and overcome my tool shortage. The second one should move along more quickly than number 1 as I learned a bit on the first one.

Can't wait to hear them together. It's hard to give it a good test by itself. Side by side with my Boston Acoustics is comparing apples to oranges. These definitely outdo them in the bass department, but the highs are a different animal, don't sizzle like the BA's. They sound a bit smoother top end. But I need a pair of them going and give them a good long listen.

I'm very happy with the results so far. What do you think?

Oh, BTW, the WAF on these is very high, my wife says I shouldn't put a grill on it, she likes the oak front so well. I do have some round crosshatch type grills that would cover only the woofers, but I don't know if I like that look.

Anyway, all comments welcome, even the bad ones, just be gentle:D

dang, for a supposed "amateur" those are looking quite pro.

good work. I hope they sound as good as they look.

I'm a tinkerer and far from a pro. The closest thing I've done to this is the wooden boom box in my avatar. I do like to use my hands and I do some odd jobs for folks in my spare time, but nothing like this. I really think I should say it turned out well despite me, not because of me.

My wife likes it so well, she said I need to make an LP cabinet to match as well as a TV/Stereo gear stand too. But I know I'm closer to Primitive Pete than I am to Bob Silva!

You should be very proud of your efforts. Those look as good as any I've seen restored. I like the inlaid top and I would suggest you build a matching gear rack incorporating that same design. :thmbsp::thmbsp::thmbsp: (that's three thumbs and is offered up only rarely :D)
 
That work is beautiful. You can be very proud. :thmbsp::thmbsp::thmbsp: I agree with 3 thumbs up.

I have another inlay idea. I already have 2 pcs of a type of corrian counter top to use on a TT shelf. I was going to put inlay them a few inches apart, side by side and trimmed in wood. They are each just big enough for a single TT. I've been wanting to get 2 tables hooked up to my main system for awhile, but I only have room for one right now and it's on a wall mounted shelf.

I'm still letting the creative juices ferment a bit on that one. Some day though!

Thanks to everyone for the great comments. No creative critism yet? It's OK, I can take it.
