Building a solid pine wood, finger jointed guitar amplifier for my Fender pro Jr.
Done the same way Leo Fender did back in 1946.
There is Nothing like the Warm sound of a pine wood cabinet!

Step 1: Measuring the four sections to be cut

The Fender pro jr. cabinet measures 14 1/2" H x 15 1/4" W x 8 3/4" D
I wanted the wood grain to match throughout the cabinet,
After purchasing a piece of select pine wood 1" thick 10" wide and 8' in length,
I carefully marked the 4 sections to be cut at 14.5" then 15.25" then 14.5" then 15.25"
Measure Twice CUT Once! Make sure to always were proper safety glasses and
read and understand the proper use of your power tools!
I used my radial arm saw to cut the sections.
butt joints with bracing all around will do just as well<br><br>real simple too. and don't even need a buncha clamps, just glue and NAIL (mesa does it that way, and they've got the beefiest cab builds of the big brands)<br><br>bracing butt joints is simple:<br><br>&gt; 1 2 2 2 2<br> 1 3 &lt;<br> 1 ^<br> 1<br><br>1, 2 - side boards<br>3 - brace board<br>^,&lt;,&gt; - nails with directional vector<br><br>glue &amp; nail the brace FIRST, and to board #1 (offset) for a good butt joint with two planes of attachment &amp; double the glue-up surface<br><br>important: use a &quot;true&quot; board for bracing... poplar dowels are crap to be avoided. maple can be nice but is crazy hard, difficult to nail, can break improperly/unpiloted screws, and weighs a ton. ALDER is your friend<br><br>if you can't find 1x1 (real 0.75x0.75&quot;) alder, go with 2x1 (1.5x0.75&quot;) and this pattern:<br><br> 1<br> 1<br> 1 3 &lt;<br> 1 3 &lt;<br> &gt;1 2 2 2 2<br> ^<br>
Arghh...<br><br>1 2222<br>1 3<br>1(3)<br>1
<p>This is great! I'm just about to get started building a cab for a valve amp I made and this instructable is very helpful. Thanks for posting, and great job on some really neat jointing :)</p>
from one guitarist to another....I tip my hat to you.<br>excellent craftmanship!
<p>Question....and if I missed it somewhere in the instructable I apologize. But what's up with the bottom cabinet in the heading picture up there? Looks like a piece of wood obstructing the speaker grille on bottom. Is that the case?</p>
Right now I have a danelectro honytone amp that I am going to make a wooden cabinet for. Your instructable used a thickness of 1&quot;. For a mini amp would I have to dial back the thickness?
Where did you find the routing template and how much was is? Thanks chad
Sorry for the delay, havent been here in a while?<br><br>I bought the Box Joint Router Template and Jig at...<br><br>harborfreight.com<br><br>4 about $40.00?<br>
Very nice work.
very nice good craftsmanship &nbsp;
. I like it. I like the SOLID timber feel and look. Still a bit inexpereinced and lacking in equipment to pull off the finger joints, but yeah this is how I MIGHT be building my base guitar amp. Me thinks the solid timber looks bettera or bestest as the case might be. 400W RMS + will ..... dribbling on... I am a HUGE fan of gelatin (hide glue) adhesives., being a formulator of said products.... That glue along the ? strips / joint lines; looks like hide glue..... But unless the dry fit was easy and perfect and all, and one had the alignment for the preassembly etc., I could see it as being a touch challenging to get it all glued and fitted up before the glue cooled and gelled. Unless it was done on thoroughly prewarmed timber joint lines in a square jig - in parts... Hmmmm finger jointing templates.... must acquire.
This is very nice, and complete enough for someone to follow and duplicate. <br/><br/>One minor point: it looks like you uploaded all your photos at the beginning (certainly much easier :-). Unfortunately, that has the side effect of also attaching all of those pictures to your introduction. You may want to remove the &quot;in process&quot; pictures from that step (it won't affect where they are in the rest of the I'ble), leaving only the beautiful finish product.<br/><br/>If you're not familiar with the (slightly weird) markup I'bles uses, you could replace your all caps with either italics, putting two apostrophes before and after the text, <em>like this</em>:<br/><pre> &apos;&apos;like this&apos;&apos;</pre>or with bold face, using three apostrophes, <strong>like this</strong>:<br/><pre> &apos;&apos;&apos;like this&apos;&apos;&apos;</pre>
