John Morton,
That is a real work of art there! How did you cut and shape the stainless?
It looks like about 22 gauge. That stuff isn't exactly 'user friendly'!

The guitar: I was mistaken in saying that it was made entirely in my shop. The top and coverplate openings were done on laser cutters, which leave no burr. I mostly work in brass, and cut those same patterns here on a milling machine. In stainless the edge tools leave me with a monumental deburring job, something I can do without.

week #3 of cj3a ownership, i feel like i've gotten allot done. rebuilt the ross box and the rest of the steering, changed all of the fluids, fixed the clutch linkage, sanded, repaired and primed the body, repainted the wheelwells, headers and bumpers and got it a temp tag, so its gotten a dozen or so short drives around town. next up is adding some harnesses, taking care of an oil leek and other minor stuff with the 225 and then getting it up to the hills before the weather turns.

No Fuz, although somewhat similar in appearance, it was much more unusual: it was Pernambuco. Pernambuco is and has been for 250 years the preferred wood for violin and similar bows. It was an inappropriate use of the species obviously but for some reason it was actually cheap and served the purpose. http://www.ipci-usa.org/
Hard as hell while not brittle at all and capable of maintaining bending loads consistently without stress failure. Deep red to almost purple-red, incredibly fine-grained diffuse-porous. It came from Macbeath Hardwoods from whom I still buy most of my hardwood, now 38 years later. It seemed not to be quite as toxic as Cocobolo although we weren't working with it for very long.
Looking back over the last 40 years of woodworking, I am just amazed to remember all the nasty species we did work with without adequate (or any) protection. I remember resawing Western Red Cedar for about a month without dust collection while we moved my company from Soquel to Santa Cruz and had to keep up production for a big job that needed that material immediately. Another time, someone brought in a giant Cocobolo cant (large slab from a log) that he wanted resawn into guitar sides and there we were sawing away without respirators, without dust collection in my very first shop back in 1974. StOOpid. We also had a client that would bring in Monterey Cypress cants regularly that we would remanufacture to 1/4" paneling for him; the whole crew just hated it, it was so irritating and would go on for many hours. The mere whiff of it became repulsive to us in short order. We had collection but the chemistry permeated the entire air volume in the plant. Like most wood aromas in commercial woodworking, they start out fabulous and become within an hour disgusting and aggressive.

5.38" Diameter x 8' rocket with home brewed propellant [81% solids loading]. Total Newton-Seconds is approximately 3800, all burned in 2.2 seconds. Flew last week in Maryland to 7176' AGL with full recovery. Gonna make more propellant this weekend.

Nice Gunkie!
Anybody remember Kelly McDonald and Dave Judaci(sic) two El Cerrito boys and Yosem climbers that ended up with a front cover spread in Life Magazine and a visit to the Ed Sullivan, "really good show", around 1962? The lads launched a rocket that surprised even the military rocketheads of that era. Believe Kelly went into medicine.

I may get around to doing that sometime, but I find it hard to stop and take photos. But for now ... I put a bunch of stuff from past jobs out on the bench. Here goes, I'll splain the photos for you:
This is the underside of the top of a guitar like the one in the previous photos. The flat piece has had the grills recessed, the edge turned down, and a tray (spun brass) soldered behind the circular recess. I make the perimeter of the guitar from one piece, which is then held within a wooden form while the top and back are inserted and soldered.
Here is a punch and die set I made to recess the grills. From L to R you'll see the 2 blocks used to press the 2 punches; the clamp plate (to keep the metal from creasing when pressed); the die; the L and R punches; a brass test piece. The punches are doweled with the die, and the clamp plate, die and test piece are all doweled with the same pattern.
This is the assembled punch/die set.
These instruments use an amplification scheme invented in the 1920's, which was really stolen from the idea for the "reproducers" in the old Victrola wind-up record and cylinder players. A thin aluminum cone is excited by the string vibrations, much the way a speaker cone is driven by an electromagnet. The cones are spun on a lathe. Here you see several cone sizes. Four of them are next to the forms used to spin them. The embossed spirals are added afterward to stiffen the cones.
My instruments use the original National designs: the single cone models have one large cone, the tricone models use 3 small cones and a T-shaped piece to distribute the downward pressure of the strings. Here are the cone assemblies for 2 sizes of tricone. A dispute amongst the original partners at National led to an acrimonious split. The defectors came up with the Dobro style, which was different to avoid infringement. Dobros have a sort of volcano-shaped cone supporting a lattice gizmo. I don't make those.
Here is a tricone which uses the smaller set. On the left is the brass tray which is soldered beneath the triangular opening, and a coverplate similar to what is on the finished guitar (which is nickel plated). Lower right is another die set: this one is used to form the S-curve in the tailpiece, which anchors the string ends.
I have made a variety of fretted instruments over the years. Here is a concert ukulele before assembly:
Somebody is reselling a unique item of mine at a shop now. It was originally featured in a magazine article, which they've posted: http://www.om28.com/sreso/haw7str.html

Ekat-- What delicate lines that console has...looks as though it is defying gravity! With the photos and pottery, it all makes for an elegant, earthy vignette. Nice!

Here are the photos of the deck. I am changing my name to Art for sure now.
This is a true work of Art.
The pattern runs with all the lines fanning out from the house. I told the home owner that it would be like the rays of the sun. It sure makes me wet.
I love this kinda stuff.
Not done yet. More to come. The handrail is going to be off the hook. Custom wrought iron.
