A properly fused HDPE pipe will never fail. As Jim has the cutting down pat. The heating down pat. Not sure about the facing part. Welding a home joint appears to need only a bit of electricity. KIS

Is using an epoxy or JB Weld kinda product worth considering? Being this stuff is about like teflon so there will be no glueing it(that I know of). The heat bond is the way since it is so strong and reliable. Even at 1/2 inch thick these should serve a lifetime or two. They are the pipe of choice for pumping abrasive mine slurries since it is so abrasion resistant. The teflon like slickness makes it good for high friction liquids.

KIS I remember the effectiveness of the hot air gun. Wife's blow dryer will do the job easily. Prefer to do at least one of the parts on the fry pan since it is such a fine trustworthy prep. The hot air gun will get the first 1/8" to 1/4" depth heated easily for a fine bond on the other part. It doesn't get much simpler and reliable.

Check out this SDR 11 6 inch pipe beast. 7" inside diameter. Wall thickness is 13/16". grrrr: says the lotto Master - Well, you've dialed back the vibrations to polish soft rocks, what about dialing things up to actually rough in a vibe? - those look like the tubs for it. 2c.

How about a vibrating rotary ? Vibes crush grit mighty fast. And only use a small bit at a time. If one was to do a lot of clean outs and added a lot of small doses of abrasive we might be surprised. May be a lot of work. Yep, those pipes would make for a long lasting vibe tub.

I think I installed 2 inch acid waste lines of hdpe. We used to use glass pipe. The pipe was limited to 3 inch IPS. The fittings were socket type. There was ring of plastic in them that had coils of resistant wire imbedded. Put on a band and torque, apply the power (it was metered and timed), retorque and wait to cool. Never would be applicable in TJB. (The Jim Barrels)

(The Jim Barrels) Looking at 60's and 70's lapidary magazines companies sold tumblers that used baby jars and larger glass jars go figure. Don't suggest using glass jars with golf ball sized rocks lol. May be surprised though, rocks do not hit the barrel as much as they hit each other. That sounds like some high tech plumbing. Mankind comes up with some crazy stuff.

On the Mini Sonic barrels I can tell you the exact plastic youp. It is Plastisol. Plastisol claims to be liquefied PVC. Seems exactly like HDPE to me. If you were to hire Diamond Pacific to re-line your Vibrasonic hopper they will use Plastisol. I believe Gy-Roc and UV vibes use HDPE. UV is Ultra Vibe I believe

The only machines I have experience with are MacElroy. I recall the welding plates needing to be 400 degrees. 400F makes perfect sense in my findings.
