My daughter’s birthday is on St Patrcik’s Day. I wanted to make her a rolling pin with the celtic knot pattern in it, but since it was going to be a gift on St Patrick’s Day, I was thinking it would be cool to make the pattern green.

In order to use the resin, and keep the spacing right, it is important not to make the cut all the way through the blank. I left about 1/8” uncut. Then, I used tape the seal up the sides, and create a cavity to hold the resin. It is also important to keep the color consistent, so make a note of the recipe you use for the resin color. It took me awhile to work out the best approach for sealing in the epoxy. Since the pour ends up being rather deep, it tries to leak out the sides of the tape. I ended up using a combination of tape, and wood scraps clamped to the sides to hold it in.

Another thing I did not think about. There were some burn marks inside the cut. Normally, if I was using an insert of a different kind of wood, this would not matter. However, since I was using epoxy, which is clear, the burn marks are visible. If I were doing this again, I would make sure to sand off the burn marks on the inside cuts.

I did like the way the pattern lined up with the different cuts.

The pin was sanded to 220, and finished with mineral oil (no wax).

This is super cool. Great job on it and thanks for the walkthrough on how you did it. It’s got me percolating on using this technique for legs on resin tables.

Thanks guys. I had one interesting thing to add about rolling pins (so this probably won’t apply to the project WalNaught was talking about). I did a little “field test” with a friend who is a pastry chef. I had rolling pins sanded for 120, 220, and 320 grit. He did not like the 320 grit. It was too smooth, and did not “hold flour” well. He also did not like the one sanded to 120, as the flour “bound” in the pin and did not rinse out well. He definitely liked the one sanded to 220 the best, which confirmed instructions I had seen on one of the YouTube channels I watched.

Just thought I would pass that along for others making rolling pins…

Great job on the rolling pins and Celtic knots, I do have a question though, I have made many pins with Celtic knots, but with wood only, how would the resin hold up strength wise if the pin was to be used as a rolling pin, I know most of the time they are decorative only but someone may decide to try it out, just wondering.

God question Smitty! I was concerned about food safety, I didn’t think much of durability and strength as most adhesives people will tell you their joints are going to be stronger than the wood. This is an end-grain joint though, so your point is well taken. I did make a duplicate of this pin, that I ended up sending to a baker friend. He has been using it for a couple weeks now and says it is working well. I don’t think rolling over dough puts much stress on the joint though.. I will say that I did stress it and try to break it just on my knee (because that’s just how I am…). I didn’t want to dent it, but I did try to just break it with my hands. Granted I could not much leverage on something as short as a rollijng pin, but I did try, and I couldn’t break it.

I will add comments on food safety based on conversations with the resin producers. They said that when the resin was completely dry, it (and any dye within it), are inert and stable and food safe.

I did give the resin an extra long time (three days) to dry before turning it as it was a pretty deep pour (a little over 2”), although only a saw kerf in width.

I would treasure that if someone made me one exactly like that. We are very Irish and St. Patrick day is one if not the most enjoyed holiday in our house. Once I get the new garage up and running I may have to give this a try.

Bill, glad to hear that you don’t lose any strength with the resin, I have cut kerfs on the corners in flag boxes and used resin to fill in instead of wood and it seems to work pretty good.
