You can shorten up that dipstick. Cut the outer tube and fit with plastic pipe epoxied back together if it is plastic. Weld a tube if it is metal. Then shorten and remark your dipstick as you add oil.
@@donwtsn I am a retired GE Engineer. Similar construction techniques DO NOT replace new design load testing. Structures distribute loads in very different ways. In 40 years of design similarities I have never seen same results on each. Making what looks stronger build in one area often transmits more load to other areas. Please LOAD TEST!!!!
I must apologise for not giving you enough info for a judgement call. I agree with you completely about stronger structure transferring stress and failure points to somewhere else. My little dig about other aircraft of similar performance was directed at some of the kit aircraft that are about today that I’m sure would not pass a load test, especially after the aircraft has a bit of age about it. I am not one to compromise structure for performance. I have been an aircraft maintainer for over 25 years doing a fair bit of structure work on many different aircraft. And worked with design engineers from time to time doing some very cool stuff. As much as I’d like to do load testing it simply isn’t a viable option for me. I don’t have the budget, room, or materials to be able to do it. I understand that the calculated option is not as accurate as a load test, but I think I’ve taken in to account and understood the types of loads that should be expected. Flight testing will be very cautious and careful
Our system is a little different in our country. As part of the registration process it will be inspected. Part of the reason why I make the videos is to have what I’ve made recorded for future references if I need to mod things. Feel free to point out what you didn’t like. Was it some things, or just everything?
you should get better cylinders before you start worrying about the baffles. the amount of blocked passages will cause overheating, and the rust needs to be removed, before you even worry about the baffles.
Yes, this is an old engine with lots of hours on it. That’s why I got it at such a low price. I also know it’s history as I know the guy who maintained it. The rust on the cooling fins should not block the air from flowing around them
Brilliant fun. A little question, I did not see a baffle between the cyclinders, like I have seen on some cowled engines, I take it, they are not normally needed on your type of engine?
There is a baffle between the cylinders. It’s underneath. With the ones I made up that wrap around the outside of the cylinders it leaves about an 1 1/2” gap at the bottom. About the same dimensions as what I could find on other installations
It looks like it'll work, I hope it does. Otherwise, the fun begins when you have one cylinder too hot, one too cold .....
That’s always fun huh! I’m hoping it works, especially at low speeds

I thought about doing that, but I wanted to make the access hatch with a bump in it more
You better do some structural load testing on the wings & gear before flight.
Cheers mate, I have used examples of other aircraft structures of similar performance as a starting point for my design. And then made it stronger.

@@donwtsn I have been an FAA A&P since 1974 as well. Get an DAR to inspect your aircraft structures. I didn't like what I saw in your vlogs....

@@donwtsn thank Don for your reply.
