Topic tags/keywords: question

This might be an example of “there are no dumb questions, just dumb people asking them”. I use a lot of Pony clamps for various projects. Some fit on 3/4” pipe and others on 1/2” pipe.. I am wondering because of the weight of the pipe, could PVC pipe be used on shorter clamps like 12-18”. I know on longer ones the pipe would flex too much but maybe on shorts pipes, would it work. Most of my projects don’t require a lot of pressure but just something to hold the pieces together while the glue sets. Any ideas?

OldWrangler,
The best way to know is for you to try.
Then you can let us know what you found out.
I personally doubt that it would work

I can used a treaded coupling on one end for that and I think on a short pipe, It might not flex too much. I’ll know Monday when I come home with pipe and threaded fitting. I’ll post results and maybe pictures.

I don’t think you will be able to slide the clamp end over the coupler. Might be able to cut the sleeve portion of the coupler down to about 1/4”, slip part of the clamp over the tube, glue the coupler on while it’s in between the two clamp pcs. Might be giving up some screw space when it’s done if it does work. You could also try gluing in a wood dowel to stiffen it up if you need to.
I think the PVC is just going to “strip” and the clamp will just slip and slide when the locking plates try to tighten down. Probably won’t handle much pressure.
Looking forward to see what you come up with.

I guess I don’t understand the question…are you proposing to simply substitute PVC for black pipe and use the Pony ends? If so I would question how long the threads would hold out on PVC and have to wonder whether PVC would even hold the tail end. With those distances I think even cheap HF bar clamps would serve you better.

Looking forward to the results of your experiment. I have great doubts about the success of this trial.

Obviously I put my mind into gear before my brain had warmed up. I think y’all are right about this experiment but I still want to try something. It’s not the price of the steel pipe clamps, it’s the weight. I have trouble putting the clamps where I want them because they are heavy. Usually I use the Erwin clamps being lighter and needing
only 1 hand. My wrists have gotten weak and give me some trouble. Maybe I should be looking for lighter clamps instead of trying to re-invent the wheel. Any suggestions along these lines?

I was wondering if you could find some heavy wall (as thick as iron pipe) aluminum pipe. I think it might want to break in the threads but it might be worth a look. Maybe a mid-weight conduit of some kind. Just brainstorming. Wood threads would pull off. Push broom handles and paint roller handles hold up well but they use a different thread and they shoulder up. What about those aluminum clamps at HF? People say they break but they have a life warranty so if they were close they might be an option. They would or should be fairly lightweight. I am watching for the results…....

I think one or more of the following will occur:
1) The pipe will shatter under the stress.
2) The tail end will not get good enough grip to hold.

That is if the pvc threaded couplings will work to begin with due to clearances.

Interesting to see the results.
Good luck.

Grandpa, no wonder people say wisdom comes with age. I had never seen the aluminum bar clamps at HF. Went online and there they were. They are priced right, reviews are pretty good and they are guaranteed. I mostly need for 12” and so I can use thee 24” or even cut them off. I resaw a lot of wood that I glue together and usually don’t glue up anything that won’t go through my planer (12 1/2”). These sound like what I need. I will let you know tomorrow as I will be at HF early.
I can’t believe aluminum bar clamps didn’t occur to me or that I hadn’t seen them at HF or in their catalog. This sounds great, many thanks, old buddy. I wonder who else might carry something like this. I’ll hunt around since I can’t fall asleep until a pill takes effect of RLS.

You might try aluminum conduit instead of iron. Be sure to grease the threads, it has a tendency to seize.

The aluminum clamps 24” are about a pound and a half. 60” are 2.5 pounds

from someone who works with pvc alot there is little strength in PVC it will break easily if it flexes much.

I have the clamps Bill mentioned from HF. They work great! I got the 48in ones because they were on sale. I would love to have some of the smaller ones.
