So I know how inexpensive plugs are, but I still wanted to give it a whirl. I’m totally a DIY guy so why not plugs. Saves me a few buck and can possibly make some too. Started out by making the mold. First I cut a 3”x10”x2” thick block of delrin plastic work was about to trash into 4 strips. Next I bolted them back together with 6 long bolts. Then I drilled a 3/8” holes in a staggered pattern 1-1/4” deep. This will be the stems of the plugs. Once all the 3/8” holes were drilled I used a 7/8” drill bit to make the crowns. I drilled down 1/4” in depth. Next step was the recipe. I have some old clean sand in a bucket in the garage, and I managed to get some Portland cement from the bricklayers at work. I went with a ratio of 3 to 1. 3/4 cup of sand and 1/4 cup of Portland cement was enough for the mold and a few flat disc. I mixed all the ingredients in a empty calcium supplement container that I cut the top 1/4 off. I added enough water to create a syrupy consistency. This will allow any air bubbles to rise out of the mix. Now comes the fun part. I started scooping the mix into every plug hole in the mold. Once they were all filled I smoothed the surface and started to shake and tap on the mold to work out any trapped air bubbles and settle the mix in in every plug hole. Followed by a top off of mix to any low spots. Dry time is two days. And Shazam! Unbolt the mold pry the strips apart with a flat screwdriver, a few taps hear and there and a wiggle of the plugs and walla. Let me know if you wanna try for yourself. I’ll be happy to give any advice about the process.
