Yellow Acrylic Stem Patch – Part 2 – Joyal Taylor (aka holymolar)


Blog by Joyal Taylor

Earlier I posted a You Tube video that Joyal posted about patching this yellow acrylic stem https://rebornpipes.com/2014/07/08/stem-patch-using-amber-super-glue-joyal-taylor-aka-holymolar/ It is part of an ongoing work in progress where Joyal is experimenting with different mixture to patch a bite through in an acrylic yellow stem. This is Part 2 of the ongoing experiment. Thanks Joyal for taking us with you in this experiment.

Since the amber superglue didn’t work well on this stem, I’m trying other things.

I tried mixing yellow and orange Fiebing’s Leather Dye with clear superglue, but the dye caused the glue to set instantly, even before I could mix it.

Next, I tried StewMac 2 part clear epoxy with Fiebing’s yellow and orange dyes, which mixed well.

Before photo of only one side of the stem, but I worked on both sides:

I used a round bit in my dremel to remove the previous amber superglue patch and discoloration. Also, I roughen-up the area in front of the bit to try to re-color that area.
Photo #2
I tried several combinations of yellow and orange dye until I got close to the color of the stem

This didn’t work out so well, either. Not only the color isn’t good but, also, the epoxy feels soft and rough to my teeth and lips.

We learn from our mistakes, so I’m going to continue experimenting with this.

Next, I’m going to remove the epoxy and try patching a third time by mixing dye powders with clear superglue.

I would appreciate it if anyone has other ideas to try for this stem repair.

Black Superglue Experiments – Joyal Taylor (aka holymolar)


Blog by Joyal Taylor

I have been waiting for this article since the product was mentioned on Pipe Smokers Unlimited Forums. Mark Domingues (who contributes on the blog) and Joyal both ordered the powder to try out. Both said they would experiment with it and report back. Joyal spoke with Mark and they agreed that he would post the results of his experiments. I have used Black Super Glue for a long time now in patching tooth marks and bite throughs on stems. I have dealt with the shrinkage and the long curing times and lived with them. Joyal has done all of us a service in doing this experiment and writing up the process and results of his work. Thanks Joyal for taking the time to work through this and document your process. It is well worth a read.

Experiment #1 – Black Superglue with Accelerator:

I used a round Dremel bur to cut a divot in a vulcanite stem, to simulate tooth marks.

I sprayed the area with accelerator and allowed it to dry for 5 minutes before adding superglue

I let the superglue cure for 30 minutes. As expected, the glue shrunk.

I sprayed more accelerator on the area and added another coat of superglue.

Then I sanded the patch with wet sandpaper (220 – 600 grit).

Later, I used micromesh pads (1500 – 12000 grit) and polished with white diamond and carnauba wax. It polished and shined so well that I couldn’t get a decent photo because of the camera flash.

Experiment #2 – Black Superglue with Plastex, as well as Behlen’s Furniture Powder:

I used a round dremel bur to cut three divots in a vulcanite stem, to simulate tooth marks.

Will use from left to right
Patch 1 – Black Superglue only
Patch 2 – Black Superglue w/ Black Plastex
Patch 3 – Black Superglue w/ Black Behlen Furniture Powder

Patch 1 – cured for 8 hrs, it shrunk. Added 2 additional layers and let the final layer cure for 24 hrs.
Patch 2 – cured for 8 hrs, no shrinkage but the surface was pitted
Patch 3 – cured very quickly, 5 minutes, but the surface was pitted

Sanded the patches with wet sandpaper (220 – 600 grit). Fortunately, I had overfilled Patches 2 & 3 and the sanding smoothed out the surfaces. Extra layers were not necessary.

Later, I used micromesh pads (1500 – 12000 grit) and polished with white diamond and carnauba wax. The patches polished and shined so well that I couldn’t get a decent photo because of the camera flash.

Discussion:
Adding Plastex to Superglue reduced the curing time (it didn’t shrink and one layer filled it up). Also, the Plastex adds strength to the patch and could be good for large patches and holes.

Adding Behlen Furniture Powder could be used if you’re impatient (it has something in it that causes the Superglue to cure very quickly). Too much powder will cause the glue to cure so quickly that there isn’t enough time to place it into the divot.

I haven’t tried it yet, but using the Accelerator first, then Black Superglue with Plastex could be a good way to go.
