- Cleaning and starting panel 5 and braces.

-
- Panel 5 screwed into the braces to created a “study on perspective” ha ha ha

Re: Zefren's Reservation Tuba
It will help it expand and push into the pores on the wood. I try to always spray my joints, regardless of RH
2x T39, 1x T60, 1x THTLP, 1x AT(not built by me) 6x DR250
I need more bass
But this gal's built like a burlap bag full of bobcats

Day 4
My cousin was off today to we started early, but not on the current tuba. We hoped by the end of the day to finish the tuba all the way the last panel. Wishful thinking but set high standards get more done right lol.
- Attachments
-
- We opened the 1st tuba and set about fixing the “damn” tee nuts the striped during the build. We gently sawed using a hacksaw wrapped with yarn until we sawed all offending screws. We hooked it up and “subjectively” the Lab doubled the Tubas power lol compared to the Peavey Lo rider tuba. We promptly went to buy more Labs for the rest of the completed tubas.
-
- The “Dead reckoning” that’s talked about with fitting some panel’s lol the straightening jigs helps. Some plywood seems to want to warp the smaller its cut.
-
- Here we sprayed the panel joints with some water to help cure the PL.
-
- Here we’re Linking c-clamps to hone panel 6 and 5, all while using cut slims to space the horn path.
-
- More Linking the clamps again to bring panels together.

”Day 4 Continued
Day 4 Continued
- Attachments
-
- Transferring, marks for panels 7 and 9 and screws.
-
- One 4’x8’ can provide 3 panels 8 it’s the only panel that not matches for the grain due to economy. The panel will still be short about 4 inches but there’s a way to deal with that.
-
- Panel 8 is a pet peeve of mind so I transfer horn path measurements to the brace so I shim the panel straight on the open end.
-
- Checking the horn path measurements on the open end of panel 8 in a dry test fit.
-
- I dry fit panel 8 shimmed squared and cut and panel 9 to fit.

”Day 4 Continued Pt II
Day 4 Continued Pt II
- Attachments
-
- Glue panel 9 and remove panel 8 and prepare the screws holes and double check measurements.
-
- Glue panel 9 in and shim square and dry fit panel 10 to brace. Prefer to lap panel 12 over panel 10 and 10 over 9. This protects the corner from chipping during construction.
-
- I found a 1960 1-inch blade drill and remembering the dent in my friend truck I decided to place hand holds in panel 10 for lifting. I prefer hands hold that mold to the hand so I got myself smiling hand holds on this tuba.
-
- This is the extension cut to fit to complete panel 9. The hand hold needs to accommodate a large palm since many of the movers in our area have “heft” …. in their hands.
-
- The hand cut out turned out to be too small so it will be cut larger tomorrow.

Day 5
17 hours, that’s what we used for day 5. WE are in a crunch to have the tuba tested by Saturday so we stayed up until it was done. I must say that lack of sleep could just be as bad as two high balls lol. (Which at the end wouldn’t have mind having) Around midnight My cousin and I pondered why we aren’t out and about drinking and dancing with the rest of our friends.

-
- 12pm – used the time to flip the tuba up and plug the countersunk screws. I found a masonry bit that would open the holes just enough to make the 3/8th plugs fit perfectly without glue.
-
- We needed to make the hand opening bigger so I grabbed and marked until the opening was big enough for the heftiest hand.
-
- The comparison of using wooden dowels to 3/8th inch plugs.
-
- Bill Fits talks of using the sealed chamber for cable storage and having used the previous tubas this would be an added bonus.
-
- After I roughed out the hole I saw panel ( #5) and said hey “if I place the Speakon connector in panel 5 then we would eliminate the limited positions we could place the tuba is we used the access panel as the Speakon outlet.

”Day 5 Continued
Day 5 Continued
- Attachments
-
- Hole drilled and labeled the position and polarity of the four prong connection.
-
- Connector installed.
-
- Temporary are installed to protect the wood during initial construction.
-
- Depending on the type of feet you choose and method you attached, you may take into consideration the amount of clearance in the well of panel 11.
-
- Plugging the holes on panel 11

”Day 5 part III
Day 5 part III
- Attachments
-
- Starting to build brace 6/12. Man I hate these braces and will often procrastinate in making them, I dunno why I just do.
-
- Grandpas handsaw has been more useful for short straight cuts. Don’t underestimate the power of old hand tools and carpentry methods.
-
- Like brace 2/8 to transfer the horn path lengths to the brace 6/12 and use this to the lower brace true to panel 12.
-
- Brace 2/8 installed with those little wings.
-
- Brace 7/12 installed much like brace 6/12 I use the horn path to crate the final bottom cut. I find its easier installing using screws in brace 7/12 than to screwing in from panel 7 to the brace.

”Day 5 part IV
Day 5 part IV
- Attachments
-
- Braces done. Time for a Sonics break I need a route 44.
-
- I got no truly level surface except the floor of the garage. Right here im preparing to cut to two boards at 45 degrees to make panel 12. Tightly clamp any sort of warping will bind the saw.
-
- My circular saw did not cut deep enough so im finishing the panel with a hand saw. Saw with the pulling stoke towards the center, its takes longer but will keep the saw from ripping the edge out.
-
- The Finished cut. Sand down the edges just for accuracy
-
- The panels joined together on the angle.

”Day 5 part V
Day 5 part V
- Attachments
-
- I used all my straitening jigs for the braces so using what I had on hand to straighten the bow out the the glued broad.
-
- Marking the minimum area that the wood finish needs to conceal the insides.
-
- Final sanding the lower horn path and braces.
-
- Staining the inner horn path now makes a nicer presentation since we don’t use a grill on the tubas. Take care no to paint too much into the joints. Paint and stain can change how PL bonds so its just a precaution.
-
- The final staining will finish after all the hardware is installed so the viable areas all stain uniformly.
