Using PVC tubes

Is it possible?

Yes! But will take a bit of work to connect the ball connectors, some people have done it successfully.

Attaching the ball connectors

1. Captive nut and glued-on end caps

  • You'd need to replace the wood screw with a machine screw to work with the captive nut.
  • The wood screws are 4.5mm x 65mm for reference.

2. Fill the ends with resin

  • Once this is set you can screw the ball connectors on with the wood screws.
  • One buyer used clingfilm and gravity to get the resin to set flush with the end of the tubes.

3. Insert a section of wooden dowel in the ends

  • You could glue it in or insert a screw or pin in the side.
  • Doing both might be safest.
  • Soft-wood would be simplest as you can just screw in without pre-drilling.
  • One buyer found Gorilla Glue worked well.

What size of PVC?

1 inch Schedule 40 is a good bet.

You could go to 3/4 inch or 1/2 inch, though they would suit smaller diameters where the sticks would look chunky at 1 inch. The smaller diameter tubes wouldn't be as strong.

The inner diameter of the 1/2 inch tubes would be about the same as the base of the ball connectors (16mm), with the outer diameter around 21mm. So this is probably about as small as you'd want to go.

Here's a link to a table with measurements for Schedule 40.

Are we making ball connectors for PVC tubes?

Not at this point as it will take a significant investment though it is something we like the idea of.
