Saw the video yesterday night of your first start so congratulations on at least getting to that point!

One question with the start - it seemed like you guys were running off the primer for quite a while after start. Was that just me hearing things wrong? If not, why run on primer that long?

As a guy who love the R2800 it never ceases to amaze me how few cylinders it takes for them to idle reliably.

The original primer system was removed from 062 long ago back in her Tanker 101 days. I have been doing mixture starts on these R2800's. I have been collecting the parts to replace the original primer system and we will put it back in the future.

My starting technique brings one item in at a time. Engage the starter and look for hydraulic lock (at least 6 blades usually a few more) and then magneto switch to both and then mixture to somewhere between very lean manual lean to auto rich depending on the temperature and how recently the engine ran last.

In the video you can see the fuel just starting to flow out of the blower drain and shortly thereafter she fires up. Watch the turnbuckles on the cables between the firewall and the carburetor and you can see the variation of the mixture control to be sure the mixture is not too rich or too lean. With ignition on and fuel flow starting up she will fire up when the fuel air ratio is just right but it is easy for it to get too rich so you need to be on your toes and quick with the mixture. This particular start took a lot longer than usual meaning more cranking. We had pumped fuel in the carb well prior for a good soak but maybe it still needed some bleeding. This carb hasn't run since July 19th. Subsequent starts, since the video, have been nice and quick like the right engine. You can count on it firing up at about the same blade each time.

It takes a while for the lower cylinders to come online but she cleaned up nicely, idled smooth and makes good power. We have a magneto issue to work out before we can fly. We almost made the air show last Saturday and if it wasn't for the mag problem we would have been there.

So far so good.

I was watching it on my tablet, so I couldn't see the turnbuckles. :) Thanks for the info though. You did a great job of getting her started and running no doubt. Always love watching a slumbering giant awake. :)

Looking good, Taigh. Are you guys going to build up a QEC with the mount that came with the recently acquired engine, it looked like a lot of good components came with it. Pardon if I missed it that you are.
When my Dad flew the Green Howard they had a QEC on a low boy at ATL which included full cowlings and I always marvelled at the spares required and the low hours between needed engine changes on these airplanes compared to DC-3, Twin Beech and of course jets.
He said they would go about 200 hours and usually it was a bearing failure in the reduction gearbox at cruise. Once he was at TWA and flying the Connie, he realized how it was that Green couldn't get over 200 hours and the airline was getting 1000 hrs whence they were removed for overhaul. TWA cruised at 33% rated power and the Green Howard was cruised at 65% rated power of which that rated power was wet!

I have two pics in period of N200G, pm me if you want them Taigh.

65% power wet on CB's. They must have been hauling. I wonder what kind of speed they were getting.

Awesome photos. Yes I would love to get copies. It looks just like our Super Ventura project except for the pressurization. Very cool.

The mount that our "new" -31 came on was for a DC-6 as was the oil tank. I picked up a spare PV-2 mount with our spares package so I was planning on setting up our spare as a Harpoon engine QEC for display on the stand. Anyone have any spare Harpoon dishpans and a prop available?

Sure missed our old girl. Good to see she's still going strong. Took the time to re-read the story from the beginning. It still amazes me. Now about that book that pulls this all together...:)

Also the original hamilton standard decal positions were visible under the paint. You can even make out the Remington Rand part of the decal since these blades were made by them and have RR serial numbers. I wouldn't have expected to see markings like the decals were applied directly to the blade as I assumed that they would have been applied over the black painted blades thus not leaving their mark on the bare aluminum.

Interesting.

Not sure if this provides any useful information, but here's an SNJ-6 possibly on Midway with decals applied directly to the blades.

Hello Mike,

Thanks for the photo. I have seen new old stock factory HS blades that are bare (chronic acid anodize finish) on many aircraft with the decal just like in your photo. What surprises me is that the blades on the PV-1 and PV-2 would have been camouflaged for combat by painting them black. If the decal was applied over the black paint I wouldn't have expected that it would have left such an impression on the bare metal. Maybe the intense sun at Litchfield left the mark through the paint.

It's a stupid thing to ponder but so am I! I should go back to worrying about the carburator serial numbers and gear door paint.

Thanks Charlie.

Taigh, they tried for 350mph @ 25,000 which took 1500hp from my notes of dad's recollections. They took off with water a lot of the time and flew the airplane from Oaktown to Miami a lot.
I was looking at some TWA quick reference cards from the L-1049 Connie and it trued 270kts at 990hp.
The Green Super Ventura was painted the same as the Howard 500, dove gray wings on center section and nacelles and fuse bottom, black and white with a bright, orangey red trim. I have some digitals from color slides of some close ups but are kind of faded. Send me your email in a PM.

Ozfuryfan,

Right now we don't have a direct use for the DC-6 mount and oil tank. We plan on using the stand to build up a display PV-2 or for our PV-1 project. I imagine that the museum could trade the mount for something.

Chris,

Interesting power settings. Really moving along. I suspect our Super Ventura will be quite the scooter whenever we get her going. Projects...


Well we started working on our Mark 13 aerial torpedo. The first phase is simple evaluation and preservation. So far she looks great considering that it has spent most of its life outside in New Jersey. The real cool thing is it is quite complete and has matching serial numbers on the tail, afterbody and air flask. It is also dated 1943.

This is a very cool addition to the PV-2. The bomb bay was specially designed to carry this torpedo completely enclosed. The PV-1 could carry one but they would either have to remove the lower doors or leave them open until the torpedo was dropped. The wing spar through the bomb bay on the PV-2 is even dished up to give clearance for the Torpedo.

Here is Steve opening up one of the access ports

Image

It looks like everything is not only in place but is in decent shape too.

Image

Image

The diaphragm for the depth mechanism which would keep the torpedo at the selected depth from the surface to 50 feet under. This mechanism controlled the depth rudders or what we would refer to in the aircraft world as the elevators. Next to this device is the gyro which controlled the direction rudders. The torpedo would hold the heading that it had at the moment it left the aircraft and would keep the torpedo on that track until it hit the target

Image

We may have imported a pack rat from New Jersey. Lots of cleaning to do.

Fantastic pics as always Taigh.

But you've piqued my curiosity...PV-1 project?

I had a great uncle who served on those and I've always wanted to see one on the ground, much less in the air. Always wondered how they made so many yet so few survive.

Can you give us a couple of thoughts on that project?

Frankly our PV-1 project is about as far from being a PV-1 as possible. Although it is still licensed as a PV-1 she has about all of the modifications that Dee Howard could have dreamed up save cabin pressurization. She is called a Super Ventura and if you get excited about the big radial piston powered executive birds then this one will get your blood flowing.

As I mentioned she is a project and has been on the back burners for a long time. We hope to get her ferryable and bring her to our shop where she will get some much needed attention. We will someday...

I would love to do a stock PV-1 especially since none are flying today. A dream would be to have a PV-1/PV-2 formation and WWII Navy VP heritage flight. The PV-1 had such a strong WWII history that not many know about. Sadly our PV-1 is so far from its WWII lineage (she flew coastal patrol with the RCAF in WWII) that it would be hard to take her back. I think she is better off representing the epitome of the corporate piston era.

Here is what she looked like when she arrived at Aero Union:

Image

Here is what she looks like today

From what the flight manual says and those I have talked to who flew the Super Ventura she is a real performer. Lots of speed and passenger comfort. Hopefully we will find out one day.

After everything looked good on the ground and a short flight we put the "new" left engine to the test and flew to our first air show at Auburn, California. Sydney set it up with the air show and was able to get us in in the 11th hour. Well done Syd!

The engine ran beautifully and we had a great show. Lots of people toured through the Harpoon and she was a hit.

Image

Image

Here is a photo that Jim Dunn took of her during a brief air to air shoot we did on the way out of Auburn
Image

Here is one that Tim O'brien took at the show on one of our passes
Image

When we returned home we pulled the oil filters and opened them up. We were delighted to find some carbon but no metal. So far the engine looks good but we will keep a close eye on it, and the right, as usual.

We hope to bring our metal making engine up to Ray at Anderson Aeromotive so he can tell us what the damages are and what it will take to make it all better. The plan is to raise funds for its repair and then replace the right engine with it. Then get that one fixed up by Ray as well so eventually we will have two solid engines that have been worked over by the master R2800 guru, Ray Anderson, and then the Harpoon will be set for a really long time. The engines are the last major project that is needed to complete the Harpoon besides the ongoing maintenance. The other project we need to complete this winter is to replace the fabric on the rudders which is long overdue.

There is new and exciting progress to report on the guns and that will be the subject of a future post. very cool progress that is deserving of a loud report!

Thanks go to Nick Veronico for finding the lead for the donated engine and thanks to Ed for donating the engine. The Harpoon is flying again thanks to you and the countless hours put in by the museum's volunteers and the crew at Vintage Aircraft.
