I don't know how successful that I will be, but I want to try and replicate the Jacobs L-4 for mine. If I can find a cylinder that closely approximates the Jacobs, I will have higher hopes of being successful. The 7 cylinders that I have found are wrong for this plane. I'll keep looking, but right now, it looks as if I need to make one to have the correct appearance.

Bill, Kestral and the rest of you engine builders,

After a little sorting and editing (cropping and straightening) here are the Jacobs L-4 pictures. This is from a Cabine WACO being restored (it was in the bare bones, so no model type) in an unrestored condition, so it shows all the oil leaks, paint chips, rust and other signs of use. Restored, all that character will be removed and the engine will look like new (see previous post of a Contenental in a UBF).

Picture
1 Overall shot
2 Straight down on # 2 Cylinder
3 Front upper # 1 Cylinder
4 Front at plug # 1
5 Front of Crankcase
6 Base of # 1
7 ¾ view Exhaust side
8 Top view both Rocker Arms

John,

Thanks for the pictures.

I just got off the phone with Jackie Schalberg (Archivist at AMA Museum Plans Service). She told me that they do, in fact, have the parts templates in hand, and that she was going over to see when we might expect to see them available through the plans service.

John, that data plate on the Jake says "Air Force Model xxxxxxxxx "(can't read it) underneath where it says Jacobs Aircraft Engine. Reckon it's one of the impressed models?

Man what a great set of photos. The Master Chief can put his signature line to work on that:

"Glue all the pieces together and sand off everything that doesn't look like a Jacobs engine."

[sm=tongue_smile.gif] GULP !!!!
That's quite a job that I've bitten off.

It's gonna have to wait for a little though. I got the package that I've been waiting on today. I have something to tell you brothers that will keep me away from the forum for a few days (Naw, Nightflyer, I ain't going to jail or nothing like that) I have been selected to be an Official for the upcoming TOP GUN event that will be held, the first week of May. I am going to be a scale outline judge for team scale. This is an honor that I never hoped to be given. Guys, I'm speechless (almost) I promise to do my best, and to be fair. Heck, I've got the ribbon, parking pass and everything.
I hope that doesn't sound like I'm bragging, but I'm ecstatic, excited, and I may even pee down my leg. Hope you guys are happy for me.

Bill,

The Williams Bros Wasp Cylinder is very similar to the Jacobs cylinder from the front with similar extra cooling fins on the exhaust rocker tower, fins on the lower section. A little work on the rocker covers, your own crankcase for 7 cylinders, a little paint and weathering and I believe you would have a reasonable Jacobs L-4 for your bird. In looking at the data plate a little closer, this may be a 245 hp engine and not a 225 hp (Engine Spec L 245).

Ken,

The data plate was hard to read in person, even with my glasses. I see where the flash caused the oil sump plug to put a shadow over the last part of the words "Air Force Model...). It was partially hidden behind the intake and only a little bit off the floor (engine was resting on the lower 2 cyliders). If the owner had been available, I would have asked to raise the engine for a better shot, but I suspect he was in the office at the local EAA monthly meeting/lunch or visiting with another owner in another hanger. When (big question) they start restoring the engine, I will try to get a better picture. The pictures are of the aircraft (a Cabin WACO)in its current state, so the engine restoration may be awhile.

Bill,

Here is a comparison of # 1 Cylinder of the real Jacobs and a shot of Williams Bros. P&W Wasp cylinder. If you use those, you could save yourself a ton of work. The last picture is of a P&W model, 14" in diameter that shows the 2 tone cylinders better.

Ken,
Your detail is just amazing! I like the idea of the electrical connectors for your flying wires. I made small hooks that I CA'd into the fuselage, then made small loops in the elastic wrapped with thread and CA. All I have to do is hook the elastic in the hooks, fast and easy field setup and on the Stearman ARF, it looks pretty good.
Bill,
Congrats on the "Judgeship" I'm confident you will do an excellent job.
Do not have any recent photos, we had nice weather this weekend and I made it to the field both days!

I kinda thought that was gonna be your announcement a few weeks ago when I brought it up... Lucky Doggie guess. I am sure you will do a great job and be back there in the future. To bad Tink (your Wife) can't enter your Shiney Tink WACO... she did pick the color and pilot figure . And remember... not all full scale aircraft are Shiney... So don't Dog the Doggie guys with their non-shiney 1/x scale models [8D]

Bill,

Congrates on being selected to officiate at Top Gun.

This will be a little late for you to complete your YMF as no time line was given. I wrote to Williams Bros asking about the Jacobs and Continental engines being added to their line of engines and Daniel Brett, President of Brett Industries, new owners of Williams Bros. Model Poducts., replied with the following;

Hi John,
oh boy, I hear you on that one! Once I get this business on it's feet, I'll be looking at what it takes to fill the gaps in the model engine world! The Jacobs was on the list for sure. Also, things like Continental for J-3 Cubs!
I'll be digging into the whole mold making process later this year.
I know some of those resin kits are actually casted from our cylinders when times got desperate after WmBros, Inc went out of business. I can't blame them, but the plastic injected type is really hard to beat for detail and durability.

This line needs to grow in order to survive, so I'll be looking at several items to add to the line!

Thank you for the input- I like to hear what people are after and on the wish lists out there!
I take it seriously!

Thanks, much Jim. Coming from one of the Brothers, that's high praise indeed. I have been racking my brain trying to come up with some kind of "quick release" for the other ends of the wires. It was always some kinds of hook and hook type thing, where I had a hook on the wire and one on the wing. Stupid me, I never thought of just making a loop on the elastic itself. I couldn't see the forest for the trees What I will probably use for the hardware end are small hooks (like brassiere clasps) screwed into the top wing underside, and the elastic tension will easily hold it in place. It will be a much easier and less obtrusive method like you've done; thanks much for passing it along.

Hope you guys will be interested in a shirt like this-

I will announce in this thread how to purchase these shirts in the coming month. I'll make it easy for you to obtain these 100% Cotton Hane's BEEFY-T shirts. This is an original design by myself and a close friend who is a professional graphic designer. This is a non-profit venture intended for the WACO Brotherhood to enjoy and for anyone else starved for neat Aeroplane themed sportswear. Hope you all like it! Stay tuned. Thanks for your comments STICKBUILDER.

Jim,

In those immortal words "Whatca talkin' 'bout Willis?" you do a very nice job yourself on detail and finish. Attached is a Stearman, similar to yours, getting a little maintenance at CCA.
