The scrap yard Piper Cub aka Silver Lining/AIRTRUK

I think this one’s going to have a lot of character….The cowl and struts will set it off…. I like the old warhorse ukie too…Bet it could tell a story or two…

Yes

I've been making logo and insignia for the yellow Piper Cub. If you want to paint it in another color please let me know.

Hello Bob, are you making another cub from the broken balsa one that ur repairing ? Or is it a difft. plane altogether ? Sorry if i am out there this morn been a long 2 weeks w/water problems that are finally fixed

I can understand where Ken is coming from. Being a carpenter, he references his measurements relative to the section he is working on. This is because floor surfaces are not necessarily square with the horizon. In a garage, the floor is usually mildly sloped to allow drainage toward the garage door and outside. Carpenters are able to take a less than perfect situation and make it look good. (I have actually seen this on the job.)

OTOH, a fine machinist will install his equipment perfectly level with the horizon, adjusting the feet on the equipment until that is achieved. Then all measurements are square. Also, it helps to prevent work from rolling off the table workspace. But, usually he will take a couple different measurements to ensure the squareness and alignment of surfaces on the work.

Your work is coming right along, Bob.

Regarding metric versus ANSI/SAE standard measuring system, when I went to college in the mid 1970's, the latter was used throughout, with metric introductions in class, in case we should encounter metrics like working in Europe. On the job, it was mostly the latter until the late 1990's.

But, in the transitional shape of things in the measuring world, I remember hardened steel bolts and nuts on my 1967 Datsun PL411 (Bluebird 4-door sedan). They had SAE heads and surfaces on the bolts and nuts, but metric diameters and threads on the shafts and holes. I found this out when I had stripped the head on a bolt, went to the autoparts store for a universal replacement, and got a true metric bolt. The Japanese did this thing because they figured in the 1960's, that most American shops were SAE equipped with few metric tools. By 1969, they discontinued this practice as far as I know.

Regarding one over the other, it is mainly what you are familiar with. I see no real advantage of one over the other. Measuring errors in one is just as bad as errors in measuring in the other.

I suppose if I could have my way, we'd be doing all things in the Base-12 numbering system (0,1,2,3,4,5,6,7,8,9,T,E). This is because with such a system, you can evenly divide by 2, 3, 4, 6, etc. without left over fractional amounts.

Still, I prefer power units of HP over Watts, torque Inch-Ounce over millinewton-metres. I guess it just depends on how you were schooled.
I guess I am just starting to show my age.

Good work Interesting idea

Bob, I think you’re landing on “character scale “ with the last two… Fun …. I like the rounded Cub tail surfaces…..Are you going to round the wing tips as well?

Hi Bob, I’ve tried to fly it but no bueno….Part of the problem is that as light as the micro switch is on the timer, I still have to give the down line a pretty good jerk to initiate it which usually upsets how it’s sitting for take off…. I may try bypassing the switch and make a leaf type switch to be activated by the pushrod…. All it takes is a touch to start the timer…

If it ever gets airborne it’s crazy pitch sensitive (no surprise) even weighted nose heavy… still messing with it though…. If anything it sparked an idea for a small space CL flyer…. I have a place beside the house just right…. Maybe I’ll try the idea on a little Ringmaster or something….

The Cub is looking great! I like the head on shot… Perfect use for that cowl….It will be a cutie when painted out and the Cub details added…

Hey RDW777 if its wants to come in on you you could use a strip of wood on the platform ? to keep in place, Kim dose this with the plastics he flys to pull the release . Good job Bob you got it under control over here .

Caricature Cub, Nice ….. Rounded tips will go well…. Hallmark sells a nice silver tissue that can be used for windows…. Use a glue stick for adhesive…. Would surely have to fuel proof though ….

Thanks Getback for the idea, Yes I’ve seen Kim’s videos and they are very inspirational…. I’ll eventually modify the timer and give it a hair trigger so it doesn’t upset so much on launch..

Robert

How I missed this, I don't know. But I cannot wait to see the finished 'Stubby Cubby'!
