Ever try Nordlock washers?

I’m going to go through them tomorrow morning and double check everything again. I did a preflight check last night and specifically checked the tightness in all the rod ends, and they were all very solid.
Did you check your set screws? I noticed that there is a decent amount of play between the D axle and the machined sleeves that fit over them. They wiggle quite a bit until the set screws are tightedned down.

I hadn’t checked those, but I will. I had used loctite on them when installing, but still worth checking.
No, I’m aware of them, but never have used them. interesting idea to use them in this use case.

Nice to see development coming further along.
I really thing a CNC piece here will sove any bending issues. Or a stiffener.
This is a lot of force to combat in a relatively thin piece of material.
The moment of intertia equation gives an 8x bonus to stiffness when depth is increased 2x. I think stiffer design will be better not stiffer material. Just my .02 cents.
I hava a furnace small furnace and burnout oven that I have yet to make anything with. This could be a good project to try a lost pla casting in aluminum or aluminum bronze just for fun. I’ll see if I can whip something up.
Do you have a sketch for your bracket that you’d be willing to share so I can design something with the same hole height?

A larger radius bend might help if there is room.
I think this piece needs to be a solid CNC’d steel triangle with two threaded holes in it

For future models it would be great to have it integrated into the hanger section as one piece

I think I might have missed it, but what is the extra piece on the hanger addressing?
Rotation of the axle/drive train if i’m not mistaken.
In my experience, the axle rotation is caused by the loose tolerance in between the D shaped axle and “sleeves” that slide over them. A tight set screw so far has stopped any movement for me.
I checked mine and both of mine are super snug
the set screws are snug, or the axles fit snug into the sleeves?
My axles/hangers (D shape) fit pretty snug when I installed them, and my grub screws are very snug/loctited in
mines were also snug but i still had that rotational play. i also changed my radius rods for stronger ones like Alex did and even thought it was improved, the play was still there
My movement is definitely in my rod ends. Screws on these are very snug, my movement looks to be in the rod end itself (same sort of movement in both ends of the rods)

the ones they came with honestly just sucked
They look worn out, or poorly made, way too much slop in that.
