Introduction: PVC Pipe Peg

Using a PVC pipe to make a multi purpose peg requiring only 3 elements.

The elements consisting of the required pipe, dowel and elastic band.

It can be used to hold clothing on a washing line, a finger splint or the holder for a finger based sensor to measure blood flow. Subject to the size and mass of the items to be held.

Supplies

22 mm dia. x 70 mm long PVC pipe

6 mm dia. x 40 mm long wooden dowel, metal tub or rod.

15.8 mm x 2.4 mm O ring or equivalent elastic band.

Drill hand or electric.

Vice.

6 mm drill bit.

Countersink bit.

Circular saw, Tenon or hack saw.

Sanding paper or electrical alternative.

Step 1: Design

The design was created in BlocksCAD

Step 2: The Pipe

From a longer length of 22mm dia. pipe using a saw cut this to 70 mm long.

Step 3: Drilling

Find the centre along the length and draw a line.

From one end measure 30 mm and mark this at the centre line.

From the opposite end measure 10 mm and mark this at the centre line.

Mount the pipe in a vice and drill 2 x 6 mm holes at the positions previously marked.

The holes need to go direcly through the pipe vertically..

Step 4: Splitting

Using the centre line as the guide, position the pipe to enable it to be sawn along the entire centre line and go directly through the pipe to create two separate pieces.



Step 5: Pinch Points

In order to open and close the peg we need to create clearance behind the pivot point which creates defined pinch points where your fingers will rest.

Angle one of the halves closest to the hole were the pivot will sit and sand this end to form a ~60 degree angle.

Repeat the process for the other half.

Step 6: Assembly

Taking one of the pipe halves fit the dowel across the width to sit equally in the two side by side pivot cutouts.

Place the other pipe half over the top to reform the pipe.

Slip the Oring over the end furthest from the pinch points.

Adjust the position of the Oring to create the required tension when the peg it opened and closed as the pinch points are depressed between finger and thumb.

Step 7: Finally

    creating a straight cut on a round piece is not an easy thing to do. If you are using a bandsaw for this function, first create a V block to hold the round pipe attach it to the pipe using masking tape and use the fence to help guide the pipe and block from rolling while cutting. you will end up cutting the v block in half as well. if cutting with a hand saw, use a back saw for best results. and again use a v block to hold the pipe from rolling.

    Glue the V block to some plywood, cut halfway through down the trough, and clamp it to your saw. Then you can push the whole batch through without having to make a V block per cut.

    good though. How do you keep the pipe from turning sideways while you push the pipe through?

    In general it tends not to turn in the V block, so you can get good results just ripping short pieces through. Having said that, I usually scribe or mark a line down the pipe. I do that by using a piece of angle aluminum which will center on the pipe. If I split a dowel it’s more challenging because a bandsaw will follow the grain, PVC is much easier because it has no grain. I haven’t ripped any long pieces of pipe. I think I would use a riving knife behind the blade to keep the cut straight.

    Used a circular saw, no need for a V block, simply adjusted the rip fence to the radius of the pipe. Pushed the pipe down and against the fence whilst simultaneously pushing the pipe forward. No roll or twisting. If you use a longer length of pipe its easier to cut down the centre to the required length then cut through the pipe diameter at the required point.. A ring of tape can be used to keep the two halves together whilst cutting through the pipe diameter to separate the two halves from the longer length of pipe.

    you could from same idea and design use 3D print to make the part with ABS or PLA, then usu TPU to make the elastic band
