« Part 2: Pattern glue-up and ideas for experimentation Part 3 of Fibonacci Mosaic box series Part 4: Just what I always wanted »

often go awry.

I had decided to experiment with the resin grout idea. There were things I was concerned about.

Would the resin be soaked up by wood end grain?
Would there be air bubbles?
How easy would it be to lay the ‘grout in?
Would I get the mix right (resin to hardener to pigment)?

To this end I made two patterns to experiment with

I masking taped around their edges so that the resin wouldn’t escape

I was ready for the resin. First problem. I’ve had it for a few months. The top part of the can was hard. The can was dentable further down though. I decided to poke a screwdriver through the top of the can. The first cm or so was spongy. Then I broke through to a liquid layer. I decanted this out to an MDPE based container. This was becoming a once only operation. I would have to think on my feet and make quick decisions as to whether to progress. Bugger!

I used syringes to mix the resin components with. 100 ml of resin, 1.5 ml of hardener and 2.5 ml of pigment. This all became very messy. It’s been over 40 years since I last played with this sort of stuff. What had I done? However I mixed it all up and put some of it in a 60 ml syringe and proceeded to pipe it into the test pieces. The result

Well what should I do? It’s now or never. I was happy enough with the way the test pieces had gone re: the process of piping the stuff in. The resin was going off as I thought. Oh blow it, go for it. I piped the pattern board too.

Making as sure as I could that there were no air bubbles. I hadn’t had time to tape the outside. Trust to luck on that one. I hoped it was going to set fairly quickly so I ignored my worry over absorbsion via the end grain. I think its OK. I don’t know yet. At 30 minutes after the last bit went in the remaining stuff in the tub had turned to gel

I can’t remember whether this is an intermediary stage on the way to hardening.Was the resin off or had I got the mix wrong? So I have ended up winging it after all. What is the result? As I said I don’t know. I’ll give it a day to harden (if it will). If it doesn’t, as a gel, I can dig it out of the pattern and try something else.

It’s not the end of the world. I wasn’t making it for someone else, on a tight time-scale. If I’ve ruined the pattern I can make another.

Be seeing you

I really hope the resin wasn’t bad. I’ve had similar results with new resin, though. In my case, I think I added too much colorant. I was using artist’s acrylic paint. After about 4 days, it finally hardened.

Tune in tomorrow for another exciting Adventure!
I’m betting it will harden up for you, but I’m curious how it will react when you begin cutting your Mitres…
Good Cliffhanging Martyn!

Wow! I am holding my breath! I use a product called Envirotec Lite which is clear but can accept color. I have used acrylic paint to color it lightly with no adverse result. I hope it works out for you. Like the others, I will stay tuned . . .

Sometimes you just have to jump off the ledge and hope you land okay! Can hardly wait to see what the results will be.

Gasp! I had resin that took days to harden. Fortunately a daytime job substituted for patience and it all worked out in the end. Can’t wait for the next episode.

It seems to be hardening and is now in a toffee sort of state. I’ll look at it again, tomorrow.

I’m waiting to see the outcome on this one. I recently had a similar “toffee” situation while embedding an item in epoxy. I used a 2 part mixture of exactly equal amounts per the instructions, and even several days later the curing had not completed as originally expected. The only explanation that I could come up with was that the original components were outdated. One comment that I would make is that when purchasing similar epoxy materials, make sure to check on the date of manufacture, and not depend only on the date of purchase.
I did try “baking” mine in the sun for a while, but this only served to soften the epoxy back to a liquid state. All I could finally do was completely remove the uncured mess, and start over.
Hopefully yours will cure properly.
