I had to fix some issues with the top, Flushed up, it
was not. The top was flush about half way across the front and my face was
bowed and the top ended being back about a 1/32 of an inch, more *&% and I
thought about it for a while. After dinner last night I got the heat gun out
and pulled off the edge band on the front face. I really didn't want to do so
but the more I thought about it, I knew it had to be done or it would look just
like the other two I did last winter. So I took some more iron on edge band and
tapered the end with a sanding block and applied it to the "low
section". I then installed a full length piece and ironed them together.
Not sure how it would look the whole time. When finished it looked pretty good
and I felt good enough that the next step could start. This morning I started
on fitting the side. I guess Its a rock and a hard place, either know that it
all fits before hand or wrestle it and with the glue getting all over me and
the outside of the cab. It finally fit pretty nice and to keep the glue rain off,
I taped and papered off the outside and then just taped off the inside with the
tape folded in half to form a glue trough. The moment of truth cane and
couldn't put it off any longer and started to spread the glue. I set one corner
at the top front with a clamp and then the bottom front next. I finished off
about 8am took some pictures of the inside just to make sure I wasn't missing
any glue and found about 3 drips. Now when I pull off the clamps, paper, and
tape in a couple hours I will find out how I did. I'll just have to wait and
see...

Hi Schu



The two holes in the Baltic birch is extra bracing to stiffen the cabinet.
It ties the side’s front and Back together and is a place to mount the vertical
brace that the back is screwed to. I finished cutting the internal cleats and
have dry fitted them. Time to get more glue on things. So far 17 1 1/4 inch screws and 6 1 1/4 finish nails is all of the fasteners used to this point, the back will get another 24 - 2 inch screws. Should be pretty stiff by then.

Gary,

Have you ever used Pocket Screws..? It would certainly eliminate a lot of the clamping/cleats and mis-alignment. Possibly your clamping that much may be pulling the "Box" out of square or cause bowing in areas that you are not expecting. In building the Jubilees and many other cabinets, the pocket screws allow for dry fitting and virtually eliminate clamping. Just a thought............

Hi W. C.

I have certainly concidered it but there is a problem, I am broke and out of work. The parts were already cut and edge banded from last winter when I did the first two and laying in a pile. The mahogany plywood was $10 a sheet (more damaged goods) that if perfect would have cost $150 to $200 for the both sides good 4 x10 sheets. I found another half sheet for $20 that was fairly close. The backs were more craigslist buys, 13mm baltic birch that was laminated last winter to make a 1 inch thick panel, 2 more sheets at $15 each. I guess I have about $100 into the 4 cabs. I learned some more yesterday about my clamping method in that I had the jaws of the clamps to far so it was applying presure to the panel to far inboard lifting the edge away causing a gap. I am not sure that any method would produce better results as the panels were not flat. This is more of something to get me though the winter and relieve the cabin fever. Its been the nicest winter I can remember but its still winter.

Gary,

I understand that you had to work with what you had. The nice thing about the pocket screws is, it allows you to make minor adjustments and will let you "bend" any warps out, to align the pieces. It will eliminate the cleats and after alighment, gluing is a breeze. The thing about clamping is, if the parts are not perfectly square, the clamps will apply uneven pressure, magnifying the warps. I understand the cost issue, but for 50 or so dollars, you can purchase the jig and bit. I was not a believer either until I tried it and I am TOTALLY sold on how it makes joining pieces together as easy as could be imagined, and it forgives mistakes. The DRY fitting proceedure is a must in aligning the parts. I have a Biscuit Cutter that is laying in the tool box collecting dust. I am now using my clamps to do any final adjustments prior to screwing and gluing. The Dry Fit feature of using the Pocket screws allows you to hide/blend any minor mistakes that have been made.

What you have done so far looks GREAT and you will get much enjoyment from your accomplishments.

JMO.....W. C.

Hi W.C.





I had a pair of Klipsch
Cornwall’s and only built these as that appeared to be the best use of what I
had to work with. Fork lift damage was why these 4 x 10 sheets were put aside
several years ago at a cabinet company. I would have rather built some other
speakers but looking at the plywood I couldn’t get the panels I wanted to cut
for the MWM clone bins I wanted to build. I settled on these corn clones
instead. I knew I would screw up on the first one built and did; the second one
is better but still sows ear quality. I had enough to build 3 when I first cut
the panels out and had originally cut the backs out of the mahogany. A craigslist
ad had someone selling two cutoffs (about a half a sheet total) so for the $20
I went and picked it up, the 2 backs became two motorboards and the backs were
made from Baltic birch that I already had at that point. At this point a 4th
cabinet came into being. I guess I was looking to build a perfect sow’s ear. My
flush is flush on most of the joined panels and is a bit better than a 1/64th
on the top where its not (several inches), probably better than I though it
would come out. Certainly better than last year’s model, a piece of masking
tape may be thicker than my worst area. I am not claiming that the methods I am
using/learning are good or best but working with what I have at hand for the
stated reason of no money and lots of time. Last year I looked at the Kreg tool
when I was picking up the edge banding. I didn’t buy it as that $50 went to get
a nice spiral up cut router bit to do the woofer holes. I was really pleased
with it and had no issues (bought the circle cutter too at the same time). I
had enough confidence in the new router bit after that I went flush as I didn’t
know what horns I would be using and thought I would just rout the holes for horn
later and flush would allow that.





The plywood was not
flat, both sides are both bowed about 3/32 of an inch in the same direction. The front has been squared true by the motorboard, the backs
being open are not, so more games to play today, I should probably rip the
backs again but I think the belt sander is going to come out instead and just
taper the inside edge on the offending area on the one side where the
interference is.

I drew out the jubilee bass bin before I built the lascala
bins and did the math and just said no as the expense added up too quickly.
Seems you are having fun and learning a lot, I am glad you are doing all of the
hard work and measuring as it may be a future project for me if things improve
for me. thanks for your input, I appreciate it.
