    Thank you so much for all the information everyone : ) Love this forum! I appreciate it !!

    Galvanic corrosion

    Hello! back from the dead (college) to ask a couple corrosion questions: if we're using 300 stainless steel that have been passivated is there a big corrosion concern with aluminum? Also, I've heard we shouldn't use stainless steel bolts with stainless nuts because of galling -- would hardened...

    Oh I see! We'll modify the Affordaplane's design to create two sides attached by a bolt then. Thank you for the suggestions!

    We did this! We used kebab sticks and hot glue to make the frame and it's actually a lot more sturdy than we thought it would be. We added 2 beams that this forum recommended, going from the front triangle to the side of the cabin which we felt was necessary after adding a "lift" force on the...

    Fantastic idea thank you! So does this mean using a drilled bolt instead of the one shown in the picture, or to have the excess material near the cable and use the cotter key to guide it? Thank you!

    haha time for some adventure! thanks :)

    Control surfaces actuators design/preferences

    Does anyone have any recommendations for cable covers? The affordaplane uses them, but they seem home-made: I was wondering if it's recommended to make them ourselves, or to buy them? We found some off VXB, but they're quite expensive at $10 each.

    If you're in the SF Bay Area and still need one we can give you a contact for someone who has one. We're borrowing it too.

    Okay gotcha - would you recommend taking any corrosion resistive measures for the galvanized to stainless surfaces or is it negligible? We just changed the design back to 3/32 cable and ordered off West Tech Rigging, which is almost 75% cheaper than Aircraft Spruce if this will help anyone else!

    Okay gotcha. We reached out to our local EAA chapter and were able to borrow the official tool to press the copper too. For your recommendation on Galvanized cables, we checked it out and it actually saves us a lot of money. All our thimbles are stainless steel, though, so will that be a...

    Awesome! Copper Nicopress it is - thank you!

    Flight Club - Ultralight Build Log

    On a completely separate note: We plan to use 3/32” stainless steel cables for the control system for our ultralight, and we’re not sure whether to use tin-plated copper or stainless steel nicopress sleeves to secure our cables. On the one hand, tin-plated copper sleeves would be weaker...

    Sweet! We'll attach the gussets as soon as the bolts come in, reinforce it with a patch, add a ring, and bolt the gusset to the spar attachment. Thank you for the process and help!
  14. maya.ayoub.32

    Flight Club - Ultralight Build Log

    Okay gotcha I understand the use of these rings then. To provide more support for the fabric and secondary as a makeshift "inspection hole." Thank you for the tip to research other planes with certified fabric covering - we'll get on that asap!

    How much to tighten bolts?

    Ah yes gotcha! I scrolled a little too quickly on the Aircraft spruce website and thought 960 only came in the L sizing. We just bought various thicknesses of both the 960 and 970 to protect the bolt from the metal and use as spacers between the metal and castle nut. Thanks!

    How much to tighten bolts?

    Perfect! Washers are a fantastic idea - I think we'll use the AN960 in the front to protect the metal near the head, then the AN970 between the nut and the metal since it's about double as thick. The bolt itself is going to be under quite a bit of vibration and rotation since it's controlling...

    Flight Club - Ultralight Build Log

    Oooo these are perfect! We’ll do some research into them and I think this should be great for the gussets/ spars. So you would recomend against having an unsupported hole in the fabric?
  18. maya.ayoub.32

    Flight Club - Ultralight Build Log

    Yes! Our CAD just broke before taking that photo but they are in the middle of the spar - thanks for pointing that out.

    How much to tighten bolts?

    Would do! But we're designing our plane from scratch. But we can check out other planes' manuals and see what they do- nice idea thank you!

    How much to tighten bolts?

    Hi Hi - another quick question related to bolts. How much should the thread be touching the metal, if at all? We're using a bolt through our aileron torque tube which is 1.5 inches in OD and the options for grip length are 1-7/16 or 1-9/16. Also wondering how much we should worry about the...
