Yes that is a valid point, knowing how to install a rivet properly is very important as a lot of damage can be done by misuse of the usually pneumatic hammer and anvil tools. I work for Boeing aircraft for a number of years and the slightest lack of focus can damag a whole part, and you're back to square one so give yourself time to learn how to use these tools, I would also recommend spring stops for your drill bits and it would probably be a good idea to offer some instruction on how to properly deburr because too much deburr can also damage your part. Great video Good question.
Really superlative. This man is articulate, precise and clearly has done this enough times to understand the pitfalls and what is and is not critical., Huge thumbs up.
Agreed. Appreciate more informational videos on the Hummel planes, it really helps someone decide whether this is a project they want to do and see just how easy it can be to build your own plane.
I know it would take a lot of work but I would love videos like this for all of the major connections and assemblies. if there are multiple of the same thing maybe only show it once but it would be nice to see it from unboxing to built.
This is really excellent explanation. While I will not build a hummel, I might well buy one, and I suggest that anyone who wants to buy one.. study these videos so they understand the construction very well, in order to be able to judge the quality of an already built hummel before buying it . I am always surprised that builder do not chromate thier parts before assembly.. although I can see that would complicate and lengthen the build quite a bit. I do not know if it would interfere with assembly ...
I'm confused. You are working with pre-drilled kit pieces but then say the holes need to be drilled. To clarify, none of these pieces come with any drilled holes, correct?
Holes are pre-drilled on both the UltraCruiser and H5 kit parts (with a few small exceptions). However, in order to meet the 51% rule for Experimental Builds you will have to drill the holes larger than what they are when shipped to you.
Solid rivets are used in the factory provided parts. Yes - they can always be put in by the homebuilder if they wish. We design for the use of the Avex and Stainless Pull rivets to make it more user friendly for builders that don't have the tools or experience to drive solid rivets. HAC
We typically do not. HOWEVER, if you live in a corrosive salt water environment then the sealant might be a good idea. On the Ultracruiser we are saving every ounce to stay within FAA Part 103.

Thank you for making these videos. Please continue to show us the entire build. Anxiously waiting the next video.👍🏻👍🏻

Thanks for share
Great job keep it up 👍
Love this plane 😂😮
Question, how much does that center assembly weigh? (and for that matter how much does the center spar weigh?)

@@hummelaircraft Got it, thanks!
Wouldn't solid rivets not only be stronger, but lighter as well?
Solid rivets are used in the factory provided parts. Yes - they can always be put in by the homebuilder if they wish. We design for the use of the Avex and Stainless Pull rivets to make it more user friendly for builders that don't have the tools or experience to drive solid rivets. HAC
No faying surface sealant used?
We typically do not. HOWEVER, if you live in a corrosive salt water environment then the sealant might be a good idea. On the Ultracruiser we are saving every ounce to stay within FAA Part 103.
