this playlist has made me realise that even lower series of racing are very sophisticated. As an f1 fan, I assumed that all other series that weren't top of their class were simple, but this is very interesting and complicated. Great videos!
Thanks. I think it just occurs naturally, it only takes one competitor to push the limits with something better than the rest of the field and suddenly everyone has to do the same to remain competitive. It can't help but evolve as people look for more and more ways to improve and get ahead of the competition.
I cant believe I am just now discovering this channel! You guys do some awesome stuff, I am designing a fuel tank for a car where we have had baffling issues. The design ive been thinking of is very very similar to yours. I was curious about any updates on the performance especially for the sump area for your pickup tube as mine runs an external pump as well and I am looking to build a sump just like that!
Did you weld on AC? I believe that your TIG welder has the option to (AC depending on Ac Balance cleans the base metals of any oxides every positive cycle and welds every negative). Your videos are very high quality keep up the good work!
Hi - your work is just amazing. I am also trying to build a race car by myself, and there is one question - I was wondering how thick each panel is, it would be much appreciated if you could share. thanks in advance.
Curious about the longterm performance of this tank, your design looks robust and simple and well made, have you had any issues with the direct mounting tabs on this tank? Typically trucks use strapping over rubber isolators to retain an aluminium tank as rigid mounts tend to generate fatigue cracks and those cracks can spread from the mounting tabs to the tank and result in leaks. They are subjected to road vibration over a longer term than a racecar, but that solution seems to work well. Depending on how many hours you rack up on the car it may be prudent to dye penetrant test your tank occasionally to check for cracks.
Yeah in hindsight that would be a better solution. To date no problems with the tank, but I think it's more because the driver basically holds it down whenever it's driving - the bolts don't have to do too much.
It's inevitable that there will be something left in the tank between races. My fuel tank's design was strong against compressive forces and vacuum but wouldn't fare too well against internal pressure - the ribs only support the external walls under compression. But it's an interesting question - maybe something like a pressure relief valve would work, allowing it to offgas but not release fuel in the event of a rollover.
Youl never be able to clean aluminum of the oxide layer as it instantly forms when it comes into contact with oxygen. Only way possible is to submerge it in a inert gas environment. This layer doesnt matter however when it comes to AC welding
Do you know how fast a considerable oxid layer builds up again after grinding the surface? i know that it takes only few seconds to build up a few nanometer thic oxid layer.
I am rebuilding my race car, a single-seater sports prototype, and need to replace the fuel tank. How important is it to have an additional internal bladder within the fuel cell from a safety point of view ?
Thanks. The undertray was designed by JKF Aero and is meant to give the car significant downforce - something that would be unique to Australian Formula Vees. It's designed, I've bought the parts to build it, I just need to find the time now. It would be another huge build not too different from the bodywork.
I didn't want to sound harsh, but to be true, I must have the technical drawings approved before start building it and I can't ind anyone interested in do it for an affortable price..... :-}

Great job.. Very sophisticated work
Keep 'em coming! Really enjoying these man
hi, nice work there, have you made any slosh simulations on that design?
WOW. Great work and great videos
Did you weld on AC? I believe that your TIG welder has the option to (AC depending on Ac Balance cleans the base metals of any oxides every positive cycle and welds every negative). Your videos are very high quality keep up the good work!
Yep, I welded on AC whenever I was welding aluminium. Thanks for the feedback.

Did you consider putting a one way valve on the breather, that allows the tank to breath but doesn't let fuel leak in event of a turnover.
Can that be a problem if the fuel warms up and you have it expand?
@@thomsenmotorsport7201 Don't you use the fuel too fast for that to happen?

@@thomsenmotorsport7201 One way valves, at least the ones I've used, allowed gasses to move both ways, only fluid is block in the desired direction.
That would be perfect then. I can't edit the video now but hopefully if someone watches this wanting to do the same they will see your comment.
Hey Simon, love your series and your videos. Question: do all aluminum’s have that oxide layer that you have to grind off before welding?
So far as I'm aware, yes.
Youl never be able to clean aluminum of the oxide layer as it instantly forms when it comes into contact with oxygen. Only way possible is to submerge it in a inert gas environment. This layer doesnt matter however when it comes to AC welding
However proper cleaning and preperation is vital to any welding process
hello! I have a question, what is the thicknes of the aluminioum plates used?
How would you recommend testing a potential fuel cell design for an FSAE car? Also, what is your opinion on baffles vs. fuel foam?
Do you know how fast a considerable oxid layer builds up again after grinding the surface? i know that it takes only few seconds to build up a few nanometer thic oxid layer.
Can you upload the solidworks file of the tank?
I am rebuilding my race car, a single-seater sports prototype, and need to replace the fuel tank. How important is it to have an additional internal bladder within the fuel cell from a safety point of view ?
I didn't consider it, it's not common in Formula Vee and wasn't required by the rules.
Isnt it dangerous to basically lie on the fuel tank?
What if it catches on fire?
I go from racing driver to astronaut.
@@thomsenmotorsport7201 Haha
somebody tell me how to mount this fuel tank from its base ?
You are quite litterally sitting on a fueltank....
That's right, adds to the excitement no? Given it's gusseted up the way it is it's got plenty of strength for the task.
yeah. it sure does :D it is quite an impressive achievement you got there. homemade race car and actually race much respect
i always wanted to ask you. what's with the carbon underplate? in your 3D models

cool! will look forward to it!

Hey mate, I was wondering if you could give me the cad designs you made up for it? i'm designing a similar system for my FSAE team
Oromo
You have made several errors.
I'm all ears, too late for me to change it now but if you have advice that others could use then adding to the comments would be good.
