> Still had plenty of prep to do; spent hours on top and bottom radiator tank, grinding the PC-7 filler I used on the mating flanges down, and then cleaning out all the bolt holes. It's almost impossible to avoid getting filler in the bolt holes, so I re-drilled all the unthreaded holes, then re-tapped the threaded ones. Started the thread tap by hand, then used a drill motor to run the tap in and out. Used a 20" disk grinder to remove the excess filler from the radiator tank flanges. I bought the grinder a few years ago specifically for this type of work. Files take too long! They do have their place, though; I'll have to use them on the flanges on the engine.. one on the head for the radiator fan bracket, and another on the side of the block for the lower 
> radiator hose connection. 
> Despite the switch to Daylight Saving Time, I don't know if I'll have time to do any finish painting this week. Maybe I'll work on the rusty front wheels 
> instead. I got the worst one needle scaled last weekend. Need to get the other 
> one done and start sandblasting. There's probably a couple of day's work just 
> in the wheels. Then I need to get them painted and new tires ordered. Valve 
> stem hole on one is enlarged due to rust. Needs fixing; I'll either have it 
> welded or use some fiberglass cloth. Still cleaning up wheel bearings and 
> hubcaps.

> Countless hours of sandblasting. I'm having to change the cabinet window 
> protector and rebuild the gun every weekend because of the heavy usage. The 
> sand needs changing every couple of weeks, and the dust collector keeps filling 
> up. The sandblast cabinet is easily my most-used restoration tool. Well, that 
> and the wood stove.

> Finally, some measurable progress! I primed all the parts I've been 
> sandblasting and rebuilding for the past several weeks. Painted all the 
> radiator parts except for the cap, plus hand crank parts and a ton of fuel pump 
> housings. It's getting difficult to get automotive paint here; I settled for 
> oddball primer last time I bought. I prefer Omni or Dupont, but the closest

> immediate task of getting this one O-12 running, my objective is to end up with 
> about ten mags, carbs and fuel pumps rebuilt and sitting on the shelf. Time to 
> get a little more efficient in this restoration business. Even if it's not as 
> interesting as doing one tractor at a time.

> When I was dismantling fuel pumps a couple of days ago, I could see my skill and 
> efficiency improving with each pump I took apart. After the first couple pumps, 
> I had all the right tools at hand, and understood exactly what was required to 
> take one apart with little or no damage or wasted time. There's no way to 
> achieve that level of proficiency when doing one or two a year. Besides, I love 
> the sight of all those shiny, rebuilt parts on my shelves!

> Time to decide what I'm going to do about the O-12's exhaust manifold. Both the 
> exhaust pipe bolt holes are corroded and way oversized. And the rear one has a 
> lot of metal missing where part of the flange has broken off. Do I want to 
> drill the holes out, re-tap and use Heli-coils, and build up the flange with 
> Pyro Putty, or just find a better manifold? The exhaust manifold also has a 
> large wad of braze on it to fix a crack.
