Haven't posted any progress on here for a while! A lot has happened since Summer '21, when I bought my 40 and started this journey. After taking a month to drive the loud, floaty, smoking thing, I got started and tore the thing apart. At the beginning I really only wanted to address the obvious surface level problems and go from there, however every time I broke a piece off I'd uncover something underneath it that would totally suck me in.

After after a few years of tear down, moving spaces, and constructing a new garage, I find myself with a totally disassembled '72 40 and a whole lot of work ahead of me. Feels weird to be putting things together instead of tearing them apart, but it finally feels appropriate to call this a build thread.

Above is a shot from about 4 months ago when I finally got the project back in the garage and able to be worked on. Since then I've tore down to the frame and got it blasted and powder coated by a blaster here in Boise. Turned out pretty great;

I've also been working on the front and rear axles. Its been a fun experience, and the most technical part of this project I've done so far. I'm taking my stock '72 drum axle and outfitting it with some disc brake parts. Shoutout to @ginericLC and @Hamachi.

Have been media blasting all of the appropriate parts, shooting them with a coat of etch primer and a coat or two of rustoleum satin black protective enamel. Has turned out pretty well in most applications and seems to be 'ok' tough. Open to suggestions for a coating that might be hardier but not break the bank. Fit with a rebuild kit, and a stud kit from cruiser outfitters. Went through all the work to get it fit, torqued down, and greased and realized the short birfs I have are too large in diameter to get into the knuckle ball :flush: so I had to take everything apart and grind the ball out a bit to get the birf to fit. Making progress! Cheers
 
I have used POR15 with good effect, although it needs to be covered with another paint as it breaks down with UV exposure.
With the Prep work you have done, it will work well. There are other brands that work as well, POR15 has been my personal go to for a number of years.
 
Finally pretty much done with the front axle! Took me long enough.

Ended up using mostly all new hardware, studs, etc. Didn't feel like skimping out on suspension HW. New bearings & races. All that's left on this is deciding what to do for locking hubs. I have the short birfs so I could do AISIN hubs but I have a set of warns I may use instead, if I can.

On to the rear and hopefully getting the frame on the axles by May? Crossing my fingers.
 
Lots of progress over the last 8 months. Shoutout to @mattressking for all the parts and support.


Continued on to the rear axle, tore it down and blasted with a pot blaster in the yard. Never ceases to be a horrible pain of a process.

Once I got everything prepped and painted, I reinstalled the rear diff with a new OEM shaft pin. Mine was pretty worn. In hind sight I might have just replaced the whole assembly with a locker.

Picked up a TSM rear brake kit and powder coated the brackets at home. Turned out nice.

With all the disc brake shenanigans happening on all 4 corners, I had some rubbing on the calipers in the front. I ended up buying spidertrax spacers before being told I could've just put a gasket spacer on, whoops. End result will hopefully look good.

On to the actually exciting part... got the engine back on the frame.
Rebuilt last year by a shop in town here, excited to get it fired up soon.

It's been fun getting some components on the engine. Mostly all OEM parts.

Blasted and clear coated the intake at home, got the headers machined and cerakoted.

This turned out really great. After ordering an adapter kit for the sniper 2300 I planned to install, I found out I would need to find a raised adapter. I saw a few online and decided to test fit a 3D printed one on my setup. I work at a large company that has their own machine shop, and one of my employee benefits is to have access to some of the sweet machines there.

The final result after providing a block of 6061... turned out pretty sweet thanks to the pros at work.

Pretty stoked for how things are going so far. More to come!
 
So what did you do to the engine? bore, rings, valve seats... what did it cost parts and labor and what shop in Boise.
thanks

In 2022 I purchased a 2F from @ginericLC, he delivered me 3 2F cores that I tore down and chose the best block and head to get redone. The work was done at Import Engine Supply, Garden City, ID.

Ended up choosing a 2F SN:053361, think its an early '75 based on SN's posted on mud. It had already been bored out once and required another bore. I'm not exactly sure what it was finally bored out to.

New parts included; Pistons and rings, cam main & rod bearings, lifters, timing gears, oil pump, cam shaft, gaskets, plugs. For the head there was one valve that got replaced, stem seals, all valve seats, guides. Total in parts ~$2,000

Labor; further disassembly, blueprinting, hot tank, magnaflux, bore & hone the block, deck the block & head, crank grind, assembly. Total in labor ~$3,600

Some pictures I captured while visiting

I'm a bit late to the party here as I just came across your thread but you nailed the most important part with getting rattle can paint to stick to bare metal - a coat or even a light coat of self etching primer.

Looking forward to watching the progress!
 
Good deal. It appears you posted it done on Friday. Is it running yet? Sorry, I couldn't help but asking. Slow and steady is the best for Cruiser rebuilds.

He's too busy skiing........

If it was carbureted he would've driven it to the mountain.
 
Huge milestone!!! Temporarily wired everything up and got the 2F fired up for the first time, with @mattressking ’s help.

Short clip of the firing. Only had it running for about 30 seconds, no coolant yet. Check it out; 2F First Start

Beyond excited with how easy the sniper setup and first start was. This was the first attempt at turning it over, started like butter. Onward and upward!
