I built two tuba 60’s for my DJ’in Cousin and he used them in few small events (everyone was floored btw). Soon we determined that we could do with two more tubas for future outdoor events. We went on a sleep learning curve with the previous tubas and I’m determined to make this one and all future ones, perfect. All the previous builds we did everything from memory and did not save our plans. So we sat down and reconstructed every little problem we had and annotated the 3rd ones plans. SO this post shall document the 3rd tubas construction day by day in real time just for fun and prosperity. Enjoy

Day-1

I thought the minimum size cab for a lab15 was 27"?

It is but most doors on the Navajo reservation have 28" of clearance and questionable construction qualities. We did a mock up of the 27" (weighted to final 250lbs) and tried to get the sub in a few venues around town. We banged hands, knuckles, dented knobs, knocked out center beams, door jams and broke a sill. 24 was the width we needed to prevent most of these accidents with a two man team to haul the tuba up 8 stairs with a 28" door.

What size light bulb are you using?

IMO you need more light to work. Just thinking safety.

Day 2
My quest for perfection ended today but only after each step after step the melting of perfect joints inflated my ego. Each step made sense and everything fit then … Disaster on the last panel. My ego deflated and I sat wondering what went wrong, sitting senseless, But its not an excuse to panic but time to trudge on and proceed while the PL is still wet.

Scribing those brace lines across the face of the panels, transferring them up from the side, is excellent technique.

Good thread.

Woke up late this morning And It was very cold. Today was slow going as most of it was spent on fixing the mistake of the previous night. Mistakes when carefully dealt with can be eliminated and time will repair your ego.
