Hello everyone, I'm very paranoid about germs so i sprayed my MOC with bathroom cleaner after someone handled it. When i woke up, at least 14 pieces had cracked or broken entirely. I can order some new ones but i have no idea what to do with the remaining MOC parts. Are they all weakened and should all the hundreds or parts just be replaced? Should i wash the other parts to try to get the cleaner off? Can i trust these parts to stay strong in the future? I'm really upset about this. The active ingredient appears to have been n-alkyl dimethyl benzyl ammonium chloride it that helps? I'd upload an image but apparently i'm out of space which is weird because i think i've only uploaded 4 pictures ever

I was able to incorporate the top half into the chest of my build pretty easily; i was already using a row of pegs to attach the obliques to so this worked out well. What do you mean by friction and slack?

So what i DO have is the turntable from the Crawler Crane 7632, which might actually work better for me because it has studs to interface with System parts better. Do you think that would be a good substitute? It seems to be REALLY hard to pull apart but i don't know how it compares in sturdiness to the one you suggested.

Hello everyone, I'm working on a 40cm tall Gundam, and I need advice on the waist. I would LOVE to have a rotating waist, but given the size and weight, I'm worried it would be a point of failure. Given the dimensions, I'd be relying on a 4x4 turntable plate and that axel to hold the 2 halves of a giant robot together. The idea being that the hips will be built around a gearbox that is re-enforced such that it can be pulled apart vertically so that the axel and 4x4 turntable plate will attach it to the torso. The end of the axel inside the upper torso is flared and can't be pulled out from this end, so as long as the tension on the hip side holds up, the build should stay together. The alternative is very appealing because if I go with one solid torso, I can really reenforce it with pegs, but the downside is that i will lose functionality and the torso will just kinda be a big ol' brick. Is there an approach that I don't know about that might help? I know Lego generally shies away from any kind of hip articulation and i assume it's for structural integrity. The alternative-alternative might be using super glue to glue those gears onto the axel, thus ensuring it can't come apart, but i feel kind of dirty using glue on legos, even if they can be dissolved later if need be. Thanks for all of your help. EDIT: so apparently i don't know how to attach images? I tried to attach two images to assist but they won't display?

That's what i thought, yeah. The ratchet joints are -marginally- more stable, i guess. I can work with that, but it feels unlikely to support something that tall. I may have to get rid of the knee joints to make it work, unfortunately.

I think they use the same small ball joint. The shins of the mech narrow to only 2 rows wide and two bricks deep at the ankle; i can't see what else could possible be there; check out the 9th image in the gallery. https://www.lego.com/en-us/product/monkey-king-warrior-mech-80012?gclid=CjwKCAjwn9v7BRBqEiwAbq1EywpYmV0zTm3oTPr-RWwxyMNQ0kXQNrqyjY4iJuUrZ0LX3P2Miq_1zxoCI2EQAvD_BwE&ef_id=CjwKCAjwn9v7BRBqEiwAbq1EywpYmV0zTm3oTPr-RWwxyMNQ0kXQNrqyjY4iJuUrZ0LX3P2Miq_1zxoCI2EQAvD_BwE:G:s&s_kwcid=AL!790!3!436398733364!e!!g!!monkey king warrior mech&Buffer&cmp=KAC-INI-GOOGUS-GO-US-EN-RE-PS-BUY-CREATE-MONKIE_KID-SHOP-GP-EX-RN-PRODUCT_NONBRAND

Hello everyone, i'm trying my best to build a giant mecha, specifically a Gundam. I am HIGHLY intimidated by the incredible Gundam MOCs out there, so i'm doing my best not to look at them. However, i do need some advice. The ankle joint of any mecha is so important because it keeps the entire thing upright. Large feet can help offset it, but ultimately a weak ankle joint will make the whole thing come crashing down. I'm trying to build a Gundam that will be largely in-scale with lego minifigs, so i'm shooting for 16-17" tall (40-43 cm) to align with the mechas from my preferred series. To that end I'm copying the hip construction to a large extent from Lloyd's Titan Mech, which you can see here: https://www.lego.com/en-us/product/lloyd-s-titan-mech-70676 I'm VERY worried about the ankles, however. My mech is looking to be about 3-4" (7-10 cm) taller than theirs, and i am not confident in the joint they use for the ankle. It's one of those larger ball-and-socket joints that are present in the link i posted at the elbow. I am worried that it won't be able to bear the weight with my extra 3-4" added on, and in addition, my build calls for knees, so the ankle will be extra important. What pieces do you all use for joints on large mechas that might help? I've seen many amazing mecha builds, but i can rarely make out their ankles. Any and all help would be very appreciated.
