Topic tags/keywords: epoxy coating question tip

Hi I’m fairly need to wood work or building anything with wood. I recently decided to build a bar table to put against a wall in my man cave. I’ve decided I want to put a epoxy resin coating over the wood slab to give it that water resistant shiny finish. My dilemma is I want to add 1/2 steel pipe around the side and back of the table to prevent drink spilling. I’ve never worked with epoxy before and I’m wondering do I screw in the steel pipe to the table FIRST then add epoxy coating or am I able to finish the epoxy coating on the wood alone first and add the piping after it cures? Seems like I could crack the coating if I do it afterwards but am I wrong? It would be so much easier if I could add the pipe after the coating cures but I don’t know?

Here’s an example of what I’m trying to do

Thanks!

Finish first. Add pipe after. Don’t worry about “cracking” the epoxy. What brand epoxy are you using?

I’m using “glaze coat” by famowood. This would be the first time I’m trying this. Thanks for the advice, I’ve literally been looking for a clear answer for a couple days. Looks like I will be doing the coat first and adding the pipes later!

definitely finish first – pre drilling the holes will lessen the chance of long cracks (should they occur).

I looked at the link to the “industrial” furniture featuring pipe legs and stretchers, and noticed that almost all of them use threaded nipples for the main part (I saw one exception that used set screws, like I did).

I made a coffee table using leftover beech from a tree I took down in my yard. Most of the wood (the best stuff) went for 2 bookcases, and the leftovers weren’t the nicest. So I did sort of a desultory job on the top (desultory=half-assed).

But I was very pleased with how the legs, etc. turned out. Instead of having to cut and thread pipe (or buy nipples of the right length), I dispensed with threads altogether. I used 1.5” raw steel pipe—not galvanized or black.

I did this by reaming all the Ts to remove threads and let the pipe slide through. The legs therefore are in one piece. The Ts for the stretchers are held at the right height with ordinary allen screws—very easy to drill and tap for these. And I can set the stretchers at any height I want, whenever the mood strikes.

I started the reaming with a hole saw in the DP. Now, I wasn’t able to find a size that would remove just the right amount of thread, so I next set up the oscillating spindle sander to enlarge the holes. Used very coarse sanding sleeves, as large in diameter as would fit. It’s surprising how quickly grey cast iron can be sanded.

Since the pipe was quite large, I decided against flanges for the feet, but instead found that 2” (?) black ABS pipe caps would fit perfectly. They needed a bit of mallet persuasion, but nothing too severe. As for the top flange, I decided to weld on 1/8” steel squares with fastening holes (pipe flanges would have been too big for my design).

Within a day, a crack started to open in one of the top boards, so I removed the top and elongated the holes in the steel to allow wood movement, and by the next day, the crack had closed up.

There is no apron on this table, and I keep waiting for the thing to collapse because the top planks are just glued, with no other reinforcement. And people like to sit on it. But so far so good.

By the way, the table is heavy as hell. Sorry, didn’t mean to hijack this thread, but I may do a write up with photos on this later, depending on interest.
