Did you get that last PM (E-mail 28 AUG) O.K.?

Yes, I got it. Can you now confirm the clamp bolts as being 0.375 diameter?

I would also like to know how the gear was attached (outboard only, or utilizing the inboard point that the two piece gear uses).
I have one piece grove gear on my project.
Should I send a PM, or can it be shared here?
Paul.

Perry's airplane is outboard clamp only, which means the skin must be left open to form a slot across the entire width of the belly.

The additional leg length increases clamp bolt stress in proportion to the length increase. Here the legs are roughly 10" taller, so stress applied to the bolts, clamps, and gear box structure would be roughly 25% higher for the same braking or chuckhole loading.

Apologies Dan. I've been away.

Answer: Installation: 3/8" inner diameter = 0.375 inch. Yes.
Place a radius block (2 parts) on top and bottom of gear leg and bolt to fuselage through the predrilled 3/8" holes.
Repeat for the other side of the fuselage. No other clamping required.

Paul, you should have the Radius Blocks then.
The Radius blocks are mounting brackets for the aluminum landing gear. Inside faces have a special radius to eliminate torsional loads on the fuselage as the landing gear deflects. The Material: 7075-T6 aluminum. For a one-piece unit, Grove, from their testing state that this is all that is required by placing a radius block on top and bottom of gear leg and bolt through to the fuselage using the predrilled 3/8" holes. Working exceptionally well on my RV8s.

BTW Dans Maths is totally wrong. The stress increase (if any) is absolutely nothing like he incorrectly asserts!

I'm curious. How is it wrong?

Well David, being curious is good, as then one may seek out the correct facts.

However, I have noted on some threads on Vans AirForce forums, the arrogance by some constituents to post blind (uniformed) statements and to challenge others dedicated work, rather than to correctly (and politely) inquiring of all the facts (Engineering and Science) indicating a degree of "self-importance and arrogance" by those individuals that I would not wish to engage with.

The author of post 09-19-2017 12:12am, (Dan) in this instance, has little knowledge (near none) regarding the unique design of my Landing Gear. He can’t, as it was made specifically for my aircraft alone, under precise engineering design instructions. Yes, that individual, has no knowledge of the Width and the Tapering, the Thickness at the Mid-Point, Radius of Bend (and therein the distortion angle) or the Flare of the Pneumatic Type Coupling or the Size of the Pneumatic Wheel.

Rendering any calculation by that individual, incorrect, mere self opinion, or if you like “ Fake News”

I fart in your general direction. Your mother was a hamster and your father smelt of elderberries.
