B80 with nothing but potential...

[Deadguy 861]

As some of you are aware, a few weeks ago I picked up a couple of basket case 8hp Horses, a B80 and a 8hp 4 speed.  Now that the 8hp 4 speed is running well, I figured it was time to look at the B80.  I got it into my workshop and started the initial exam.   Everything is covered in peeling red barn paint.  All the control cables are rust frozen.  The fuel line is dry rotted.  The transmission is lubricated with ice.  The wiring is...questionable. The engine is not seized. The metal is mostly straight, though there is some rust. Tonight I managed to do the initial exam, loosen up the throttle cable and governor linkage, remove the fuel tank, and remove a critter nest from behind the dash.  So far I see nothing but...potential?

April in northern WI... how long until the transmission ice melts?

A pressure washer may be in order... Wonder how much peeling paint it would take off?

[AMC RULES 37,127]

 You're gonna lose a lot of patina.

I am thinking a pressure washer is in order, but with temps over here still around 10, it might be a while.  Given that the original paint was covered in barn paint years ago, I doubt there is any patina to save.

Now the 8hp 4speed that I got with this B80 has a freaky sweet patina. It’s a shame that my wife is making me sell it once it’s rehabilitation is complete.

Let's see now, is this one the 8HP or is it the B80. One in the garage one in the shed.....she will neve know you still have 2 of them

June?

 

 

 

B80 looks like it would be a great runner.

Fix it up and use it.I have a B-80 at my house in the Adirondacks.Has a small rear discharge deck on it.Surprises me how capable the little Kohler 8 horse is.And.......it sips gas.Have fun with your new toys.

 That will buff out.

 

Or, you can do it all with very little elbow grease. paint like that will come off in the electrolysis tank. It will take a few days, but the dividend is not removing any metal that is not rusted. The rust even comes out of the pitted areas and they can be filled successfully. On a job like the hood, you need big fat annodes. Maybe 2 inch angle iron or fence posts...Plenty of wait time, but not a lot of work

 

 If you decide to use just abrasion, these little beauties work pretty well so long as it is a larger flat area. A bolt sticking out will tear them up.https://www.harborfreight.com/4-1-2-half-inch-nylon-abrasive-wheel-94017.html

This electrolysis doodad sounds interesting....

I use junked disc brake rotors and weld an old bolt on them to hang them at the ends of the barrel

  Yep. The main thing to remember is to keep wire brushing the annodes morning and evening at the minimum to keep the rust flying off the part you want to clean. A manual battery charger is better than one of the new electronic ones as well. pfrederi has a great setup with the big surface area a brake drum provides

 To the man working on a dirt floor and ice still on the tractor. I was raised to make do, but you are one hardy soul!! I am a wimp, I gotta have a concrete floor and heat now that I am older. Hats off to ya brother!!

A project is to be done. Best of luck. Good machines, I have had one. Gave it to my friend, he luvs it.

Never thought about cutting a barrel that way!  Nice!

I have it on a heavy duty movers dolly so i can move it around. (slowly to avoid sloshing) Takes two passes to do fenders and hoods wish I had something bigger.

Right now there is ice on everything, the overnight lows are still dropping into the single digits.   And to think that one year ago on this day, the ground was already thawed, i was plowing the garden, and it was in the 60’s outside!

I have 2 or 3 275 gal oil tanks that I intend to use.  One for a sandblaster, another for a molasses rust removal tank and if I'm careful for an electrolysis tank.

 

But, BIG tanks take LOTS of liquids.  Not so bad on the electrolysis side but more so on the molasses side.  Or other chelating chemicals 

 

A wooden frame and some heavy poly (with some protection!) might better suit your needs if your barrel is not big enough.

@DennisThornton Molasses as rust removal ? Give me details

Measure the minimum size you need and get a box store storage tote a bit bigger.

Unbelievable but true!

 

10% molasses and 90% water  Maybe twice that concentration and heat helps

 

Black strap molasses is from the third boiling and contains relatively few sugars and a concentrated spectrum of minerals like copper, calcium, magnesium, potassium, and iron. This concentrated combination of minerals creates the chelating process to remove rust. So, it's important to get Black Strap Molasses. Small quantities can be found in some grocery stores, most health food stores and restaurant supply shops. Larger quantities can be found at feed mills.

Molasses owes its properties to cyclic hydroxamic acids which are powerful chelators of iron. (benzoxazinoids)

        And to think, we just added it to cattle feed. I guess the cows stomachs didn't rust!

I worked at the CO-OP all through high school and you didn't go in the molasses pit without a fresh air resperator or the fumes could over take you. At least thats what I was told!

My first run was with molasses was with cattle feed molasses and I thought I'd found the bargain way to buy it.  It worked but it has SO much other filler that I think it's better to buy straight liquid instead.
