Q: How tight is the joint? I want to use it to make the upper body of a life sized mannequin bend over forward and then stand up straight. The upper body weighs about 20 lbs. Would one or two spider joints at the base of the spine be strong enough to help the mannequin stay standing up straight? Also, does the joint stay tight or does it loosen with use. Thanks.
A: Hello. For a 20lb load, I would definitely recommend using a twin spine setup with 2 Spider Joints to support it. Our joints have teeth in them and will not slip once tightened down. You will need to loosen them again each time you want to change their position.
Q: trying to use these for hired angel wings that open and close. Can these bear the weight of a length of cotton fabric?
A: Hello, yes the joints should be able to handle a load like you are describing.
Q: what size is the spider joint SJ1 1 inch ?
A: Yes, currently all of our fittings are 1 inch.
Q: Do you offer a discount with bulk purchases?
I may need up to 48 of them.
A: Hello, yes, there is automatic quantity pricing on the site. There is a drop down button just under the add to cart button where you can view the discounts. At 48 joints they would drop to $2.98 each.
Q: The Shipping is per piece?
Hi Edgar, Shipping is based on weight. The cart will figure out the shipping based on the items placed in the cart. That shipping fee is for the entire order. If you have any questions please email us directly at [email protected]
and we'll be happy to assist. Ryan
Q: Can the Spider Jointd be left loose so the arms or legs move freely?
A: Absolutely. We recommend placing an 1 1/2" diameter fender washer in between the two halves to provide smooth movement and keep the teeth from grinding together. This is how we build the joints in our animated Ground Breaker kits. We can provide you with washers upon request. Thanks!
Q: Do you have a clamp that can be attached to the end that can be adjusted? Can I place the other end on a standard pipe...my project is a 36"hoop clamped on the adjustable end and the other end would be attached to a vertical pipe....which will be put in a big planter as supporter of the pipe. I would like to use PVC but not sure it could handle the weight being only clamped on one side...thanks so much for reading this and giving me some guidance...I just found out what those adjustable elbows are called..THNK YOU!
I think I follow your idea. What size (diameter) is the hoop? So basically you want a vertical PVC post that has a clamping mechanism at the top to hold your hoop? I currently do not have any pre made parts like that, but depending on what the hoop is made out of, I might be able to help you figure something out. You can email me directly at [email protected]
Q: I am making a howl wing that open and close. Can I use the spider joint to open and close the howl wing?
A: Hello. Yes, our Spider Joints can be made to move freely by adding a fender washer in between the 2 halves of the joint (that we can provide). Performance of the assembly will depend on the amount of load placed upon the PVC pipe and fittings. I might suggest purchasing a single joint for testing purposes. Thanks!
Q: how much the weight of 1 piece?
can you send it to Indonesia?
Hello. Each Joint weighs almost 4 ounces.
Yes, we can ship anywhere. Please email me a list of the items, quantities, and a shipping address and we'll be happy to get you a quote. [email protected]
Q: In standard PVC fittings (like for sprinklers), the insides of couplings (elbows, T's, etc.) are tapered so the fit gets tighter as the pipe goes in further. Are these made the same way, or is the inside diameter uniform? If the latter, how are the pipes held in place?
A: Hello, The socket ends on the Spider joints are not tapered. We supply 2 self drilling screws with each joint purchased. these are used in conjunction with the slots on the ends of the joints and will allow you to reposition them at a later time if needed. If you go to our Prop Plans page, you can see the Hints and Tips for the Spider Joints there. Let us know if you have any further questions. Thanks!
Q: If you add the indicated washer, and leave the hinge untightened, does it swing freely or is it still posable at all? (IE will it stay where I put it, or go where gravity wants it)
A: Hello, once you add a washer to the joints the teeth are separated and the joint will no longer hold it's position under load. You could tighten it enough to still be poseable, but I would not think it will stay in place under any load at that point.
Q: How durable are these? Are they waterproof and will they crack under pressure? Thanks!
A: Hello, The Spider Joints were not designed to act as a structural member, but overall they are very durable. Water should not be a problem for them. They are not manufactured with UV resistance so leaving them outside for long periods exposed to the sun could eventually cause failure. Not know what sort of project you are hoping to use them for, we might suggest ordering a sample for testing to see if you think they will work in your application. Thanks!
