Bolt terminology


Hello,

Building a project and diagram calls for installing up stop and down stop bolts. I don't have a clue what they are talking about. Please help!
Thank you so much.

Yours truly,
Mr. All thumbs

Bolt terminology


Never heard of those terms when naming the parts of a bolt.
Just a function bolts can preform.

I'm building a swing toy for my kids out of PVC and it calls for these bolts to attach 3" pipe to the 1 1/4 pipe.

Thanks for your reply.

That terminology is sometimes used where a bolt is used as an adjustable stop. If some object is moving up and down, and a pair of bolts are used as adjustable stops, then one would be an up-stop, and the other a down-stop.

You are aware PVC has 0 side load strength.
It will sag just under it's own weight.

You would think so. Im Building it according to plan. Total length only about 4 feet. PVC is schedule 40. Hope the guy who designed it knew what he was talking about.

PVC is also is not UV protected and the fittings and pipe will break down and crack.

You don't want to get silicone on PVC either, it will snap under no pressure at anytime.

Thanks for the info on that. Good reminder on the UV issue and I wasn't even aware of not using silicone.

It will be an indoor toy at all times. It will be like a flying simulator with gimbals and castor bearings that will be controlled with a joy stick.
The plans look well done, detailed and very professionally done. Plan calls for using 3", 2", 1 1/4" and 1" PVC. So far Ive cut and pieced together all of the pipe without any problems. The bearings will allow you to pitch and roll as you sit inside of it. Looks like a lot fun but I was confused on some of the terminology like the stop down and stop up bolts.
