From the outside, that doesn't seem worrisome. You're making canvas, you have brushes, the fact that you don't know every stroke ahead of time is as it should be.
I think this statement is perfect

Modern bikes seem to have so many layers of perfectly interwoven plastic and composite materials, which are absolutely functional, but which can conspire to hide the basic form of the bike, and the cheapness of the individual parts makes the whole thing feel less, for lack of a better term, heirloom? As the form is lost and smoothed over, the integrity of the bike is smothered.
As I type this, I feel like I am attempting to name something that permeates many areas other than motorcycles- so many aspects of life seem to be objectively improved but viscerally distant or even disconnected.
Back in the 70's, when we lived in Pennsylvania in that house that was built in 1724, my dad bought a metal detector. It was very cool thing and a great idea as the property was littered, literally, with tons of things. We found coins, axe heads and lots of trash. My favorite thing was this horse. I have no idea how old it is but it was on the weathervane of the old barn which burned in the 1800's so it's at least that old.

Some of the welds were better than others but it fixed it up. I'm sure I destroyed any value it had but that probably happened when it broke anyway. Nadia is in her horse stage so now she can have this neat thing that I found in the ground with her grandfather.

... To get the weight down I want to build the tanks from carbon/kevlar (another learning curve!) and, just maybe with Sean's help, I'll explore titanium for the frame. I don't think I can become proficient in time so I'm considering options. But I find I don't like paint more and more as I go. My bikes are best raw, showing the work - like the way that I draw showing construction lines. I want the process to be seen in the result.
Gregor
So my goal is a bike that weighs between 330-350lbs (dry) or about the same as a 690, and makes about 80-90rwhp.
It's funny- we've hit on the same formula. Continuing the tangent...

Gregor has seen this bike if I recall, but this is a 2012 KTM 450 RFR, which is their factory rally racebike. It was adapted from the 690 rally that preceded it. When the Dakar went to a 450 formula, KTM tried a number of different things and all their pilots preferred the 690 chassis with a 450 sx motor slotted in. The trellis frame gives incredible stability, the whole package shares very little with the 690 enduro that has been sold here.
The cool part is that the 690 motor still fits, using all OEM parts (OEM but a bit unobtainable). Lyndon Poskitt has travelled the world on such a bike, and when I got this bike, I traded him a spare 450 motor for a 690 motor built to his spec. We didn't go wild, so it's more on the 70hp end of the spectrum... but last week I decided it was time to get moving on this project and put it in.

When I finish, I'll have 70hp and 300ish lbs dry, on factory suspension and 10 gallons of fuel capacity.
But I won't have made my own bike. You'll have me there!
One thought: I've got spare tanks for it. I wonder if they would make a good mold for the outside shape of your project? The rear tank in particular might be relevant? If they would help get in touch.
Back to lurk mode.

I really enjoyed reading this discussion on the chase for the perfect bike and changes over time that have disconnected man from machine. I REALLY look forward to following along as you build your dad's bike into something special.
That said it did rattle my iPhone’s camera to death.










Next is clear satin polyurethane on top of the dried shellac. This is supposedly a no-no but then all the things I'm doing are supposedly wrong but they work.
The process is this: sand with 150 with the Festool sander, one coat of amber shellac, dry, second coat of tinted shellac, dry, some boards get a mid second coat - essentially a heavier second coat to make them darker for variations sake.
Gregor, what kind of sander are you using? My old bosch sander broke down so I'm in the market to up my sanding game.
So tomorrow I'll open a can of worms on another project I've been messing with - gunsmithing!
Gregor
And now to answer the question of the sander - illustrated with my new bench light.

I have two: this Festool ETS 150/3EQ and a Rotex 150 FEQ but it's this one that gets all the work. I've had it for just less than 20 years as one of the first Festools I bought and I use it for 90% of everything. The /3 is the stroke size and this is the smaller, finer of the options. The 150 is the disk size and I wanted both my sanders to use the same size medium plus the 150mm size is pretty ideal. This sander has paid for itself a dozen times over. Once the switch broke but I was able to order a new one and replace it myself (Festool sells parts to normal people to fix their own tools) and it's not stopped since.

I’m in for gunsmithing. Before wife and family I poured a bunch of money into my Ruger 10/22. I have a few other guns now including one I’ve contemplated making a biathlon style stock for.
Matter of fact, I’m in for just about any subject you want to cover. I’m not a coffee drinker, but I find even those discussions interesting.
Competing for fun makes it a toy, not a tool.
Competing for money, turns the same device back into a tool.
So tomorrow I'll open a can of worms on another project I've been messing with - gunsmithing!
Gregor
Oh we’re not competing for fun. Its important to have a bunch of lefties in the local pistol league crushing everyone else at shooting.
Gregor - The Dremel troubles me. I would have thought you would have gone down the Foredom rabbit hole and found an excellent used unit which can also be budget friendly.
I do enjoy all the projects that you immerse yourself in, especially the two wheel kinds!
