I have a newfound respect for what everyone says when they say they are "90% finished but 90% left to do"!!!! I feel like I should have been finished with my build last spring!! I can safely say that

There was nothing scientific about how I tested the glue. 3M does publish some strength info but I'm just one step above a caveman so I was more interested in more of a common sense result. I would

So this was a “peel strength” test, not a “shear” test, right? And I do think peel strength is the parameter of interest. If so, good info . . . qualitatively anyway – i.e. a comparative

Excellent data, thanks for sharing it! I intend to construct my doors with 3/4" square 6061-T6 covered with 0.020" 2024-T3. I wonder if this would yield similar results?

In the event that anyone was curious about a couple of the glue options for bonding the aluminum skin to the door frames, I made up a little sample to test the 3M 2216 vs the 3M 38315 panel bonding

The plans call for a step down in tube diameter outboard of the connector tube to match the tip dimension. ?This is a welded splice at this transition. ?Why not just flatten the tube to transition

My prior project in another lifetime was a Spencer Aircar.? Unfortunately the folks who bought the design rights from Spencer did not keep things going very well.? All the assets are currently up

Just beware that having the engine an inch forward will really effect the CG of the plane! Check the real weight of the engines, not the published weights. John Haedtler

Both CG for the slightly lighter engine and maintenance access. I’ve replaced the generator with an alternator to shed weight. Got rid of the vacuum pump. No fuel pump. I do like to have plenty of

Thank you Robert. ?Zero/Zero on thrust and 10 inches. ?Easy! What drove you to add the inch on the engine mount - CG, access, or something else?

Michael, I recently installed my O290D on my Tailwind project. I used drawing #29 from the W10 set but with a spacing of 10 - 3/16" instead of the 9 - 3/16” shown on the drawing. I did not add any

Ok, let me try ask this another way… Given a conical mount Lyc 4 banger, what is the current, accepted distance from the firewall to the front of the engine mount spools (the engine to mount

Appreciate the insight, guys. ?Has the engine location evolved over the years or is the XYZ and thrust angle stable? reason I ask is because the Starduster design has had some fairly radical changes

Here are a couple of pics. If there are any other area’s you need pics of let me know and I will see if I have any of them.

Jim is correct, 68X is conical and I will see if I have some pics of it when we had the engine off. Dom

Copy. ?I have enough info for a material order now. ?My thanks

Just a vague recollection that it is similar to the typical W10 dynafocal. Pretty sure the CAFE W10 is conical. The Flamini brothers might have a photo.

Can you describe the changes Jim?
