homemade cylinder

Greetings!

I recently bought the PumpWorx pump, gauge and cylinder from LeLuv. The cylinder I purchased was 2-1/4” I.D. (inside diameter) x 9” long.

After reading here, I decided to get a 2” I.D. cylinder, and chose to make it instead of ordering it from an online vendor. I purchased a 12” piece of 2” ID x 1/8” wall clear polycarbonate tube from McMaster-Carr (#8585K28) along with a plastic hose Barb (6mm barb x 1/4” male pipe thread) the McMaster-Carr part number is #5218K266.

I covered the tube in 2” painters tape to keep it clean and sawed it off at a hopeful 9-1/2”. Having a machine shop, I lathe turned the ends square and neatly chamfered them, but those without such tools could accomplish the task with files and sandpaper…

I also machined an end plug from scrap PVC bar stock that is threaded to accept the barbed fitting. It was ultimately glued into the end of the cylinder.

Here’s the fun part though; the end that sits against the body needed to be smooth and comfortable. I fired up a basic propane “plumbers torch” and gently heated the last 2” of the polycarbonate tube by rolling it in my hands about an inch about the flame. Though a hot air gun would have been better, I didn’t own one.

After about a minute of heating the tube, I shoved it over a metal funnel to initiate the flare. Once the flare was started, I re-heated it for another 20-30 seconds and then pressed the flare against a smooth block of wood to flatten it out.

Voila! A perfectly smooth and neatly flared tube!

I would love to post a couple pictures, but I believe that I’m too new to do so. If anyone wants to try something like this, I’ll be happy to help. I’ve toyed with the idea of making the pvc end plugs in quantity, but it’s also something that could easily be 3d printed!

Cheers!

Looks like you’re set up to make your own oval tube if you want to explore that route.

My first, I used some 2” clear plastic tube, machined the end cap from aluminum, and used silicone sealer and a thumb press fit. I made it 9” long, then later sawed it off to a more-realistic 7”. The aluminum eventually turned a mottled gray, which didn’t hurt anything, but I had liked the spiffy “machined aluminum” look.

I made a large (maybe 3-1/4”) PVC “donut” ring to attach to the bottom to provide a radius, but I found that simply radiusing the bottom of the tube was comfortable enough at the time.

I used 2” tubing, which had an inside diameter of 1-3/4”, as tubing is sized by the outside diameter. I wondered why my 2-1/8” LeLuv tube felt so much larger, until I noticed I could slide my old tube inside it and rattle it around. Penis cylinders are typically dimensioned by *inside* diameter, which technically makes them “pipe”, but “standards are wonderful, there are so many to choose from.”

The heat and funnel are amazingly comfortable; I’m wearing it presently at 10”/Hzg with zero discomfort! We’re definitely a creative group ;)
