I’m glad it was helpful, Thank you for watching!

[@alanfreedman5877]

Thanks so much. I just successfully used this technique with one variation in which I was able to clamp the tape-covered forms instead of screwing it.

[@whiskyrivercustomwoodworki2012]

Hell yes! I’m glad it worked out for you. Thanks for watching 🍻

[@MDorps]

Great video! Thank you for producing it!

Thank you for watching, I really hoped it helps!!

[@ailbheskyfeather174]

While I probably won't be needing as big a setup as you've got here, this video was really helpful! I'm building a banjo for the first time, and the neck blank I ordered has a big ol' open knot in it. Now I know how I'm gonna take care of it! Thank you!

[@whiskyrivercustomwoodworki2012]

Thank you for watching and I’m very glad it helped!! Good luck with the project, I hope it turns out great!

[@ZeeOwens]

I've watched many videos on these epoxy pours, etc. and find yours to be the easiest to watch. I feel like i can repeat what you have done. Great job with explaining things.

[@DennisDolan-fl3mw]

will the silicone dam stain the wood?

[@whiskyrivercustomwoodworki2012]

No, that’s why the silicone is the key!

Thanks for sharing! You are correct there isn't much on the internet about this exact thing...

[@whiskyrivercustomwoodworki2012]

No, I always struggled to find stuff on it. Hope it helped!

[@missylee5]

Thanks for the video! I wish I would've watched it yesterday before starting my project. Putting the hot glue around the voids would've helped, as I filled them with colored epoxy and will be topcoating with clear, but the colored overran the voids. Hopefully I can sand out the color that stained around the edges.

[@whiskyrivercustomwoodworki2012]

I’m glad it helped!! One thing that I’m not sure I added in the video was about the staining with color. I’ll be making another video soon. The tip I’d give you for that is to put two coats of polyurethane around the voids prior to filling. That creates a barrier to stop any color or epoxy from creating the stain ring around your voids.

[@codyzook7022]

Thanks for a great video man! I’m doing some epoxy work for a grad class, and this helped a lot! Some questions still though: -Have you had problems with the hot glue soaking into the wood? -What is the best way to remove epoxy after the pour? -Do you coat it al all in the inside to prevent leeching? Another thought: The reason for the “epoxy stain” is because wood has pores, and the epoxy seeps into it. This is seen most clearly is woods like oak and walnut, but is true of every wood to some degree

[@whiskyrivercustomwoodworki2012]

I appreciate it! Hope it helped ya. - No, the hot glue won’t soak into the wood. If it does for any reason, light sanding will take care of it. - depending on your equipment or capabilities, a planer with a helical head or a router sled table are the best options in my opinion. If that is not an option, than a belt sander is just about the most efficient way to remove a large amount of epoxy in a hurry. Yes, I coat every inch of the wood/substrate the epoxy will touch. This is for preventing air from escaping the wood and causing bubbles as well as leeching. More so to prevent the air bubbles and provide good adhesion. - since this video I have changed my process some as far as the epoxy staining goes. I now put 2 coats of polyurethane on any surface there is potential for contact with epoxy. This creates a barrier so that the epoxy, colorant, and metallic can’t penetrate the top of the substrate. Sands of very quickly after as poly only creates a “plastic cap” on wood. It doesn’t penetrate very deep.

[@jonretter8458]

Wish I saw this a week ago. Great tips. I dealt with a huge leak that could have been prevented

[@whiskyrivercustomwoodworki2012]

Thank you! It’s a steep learning curve no doubt. Hopefully it’ll help ya in the future 🍻!

[@rudsaki]

I learned 2 things watching your video right after I tried my 1st sacrificial wood piece. First, don't round off the ends before epoxy, can't tape them right. Second build those little dams around the cracks, stuff will spread!

[@danielparker6102]

You answered my question. Thank you.

[@whiskyrivercustomwoodworki2012]

Glad I could help!

[@Studio57az]

Your right about the epoxy staining!! Especially on Rubio

[@whiskyrivercustomwoodworki2012]

It can be a real let down if you don’t know it’s coming lol.

[@Rocket62AL]

The hot glue surrounding the fill areas is brilliant

[@whiskyrivercustomwoodworki2012]

It is a life saver not having as much to sand back off for sure.

[@CaptTPT]

Nice discussion. My only issue is the Silicone. No problem if you cut the end off. Problem is if you inadvertently loose a drip on your wood surface. Nothing in the way of finish, of any kind, will ever stick to it. Best to use non-silicone caulk. Then you never worry about it.

[@jacklawson3769]

Thank you for sharing this, sir. I'm prepping my first slab ever (8 foot of American elm, 40 inches wide) and I have a few knots to fill. Do I need a deep pour epoxy for knots because it is several inches thick? They're really narrow.

[@whiskyrivercustomwoodworki2012]

Not a problem! I hope it helps you. Yes you will need deep pour epoxy of some sort. Depending how thick the slab is/depth of your pour will determine what one. Be sure to read the product descriptions before you buy, they will tell you what you can and can’t use the epoxy for. Always use the depth or thickness of your pour, the width doesn’t really factor in. I use wisebond deep pour epoxy, and their product is good for 1/2” - 2” thick pours at a time. Most products will give you a range like that.

[@scotthall2547]

Thanks for sharing, David. Question…. Do you think that putting a light coat of polyurethane around the fill areas would prevent the staining if I slightly overfill? Easy to sand I assume yet do want to avoid that stain you talk about

[@whiskyrivercustomwoodworki2012]

Absolutely! That’s what I do to prevent the staining when I pour. I would suggest doing at least 2 coats to be safe.

[@kreativbuilds]

What epoxy do you use for those larger knots / deformities ?? I just rough sanded my walnut table top and have no idea what to use. Was thinking total boat High performance but worried the knots and deformities are too deep and big

[@whiskyrivercustomwoodworki2012]

I have always had great luck with Wisebond Deep Pour Epoxy for the bigger knots and cracks. Depending on the size, humidity and temp it generally takes 2-3 days to harden up enough to de mold/move if needed. Ideally 7 days before you start milling or sanding it. I have in some cases used the regular epoxy to fill in super small cracks and knots but I don’t recommend it as it can not cure properly. Wide bond also makes a quick cure epoxy that I think you can pour up to an inch but it’s very temperamental and cures insanely fast so it’s very hard to work with. You really have to be on the ball when using it but I’ve had good luck with it as well. Hope it helps!

[@kreativbuilds]

@@whiskyrivercustomwoodworki2012 awesome thank you. Deep pour it is for those bigger sections. One last question; is there a minimum amount needed to mix deep pour ? or can I just mix any amount (even if very little) as long as the mix ratio is correct?

[@whiskyrivercustomwoodworki2012]

@@kreativbuilds I would not mix any less than 6 oz. The reason being the smaller the amount you mix, the easier it is to get the ratios wrong. If your off just even a little bit the epoxy will not cure. So I always mix 6 oz just to be safe. I have mixed smaller amounts but I used a food scale and mixed it by weight. You will have to get those weights from Wisebond because the 2 parts don’t weigh the same per ounce. So just mixing 2:1 by weight will cause problems. Does that all make sense?

[@kreativbuilds]

@@whiskyrivercustomwoodworki2012 perfect sense. Thank you so much. Great video

[@judylawniczak4545]

You mentioned you would do a video on making a form when the hole goes all the way through the wood? Is that avail yet?

[@whiskyrivercustomwoodworki2012]

It will be soon! I have not had many epoxy projects lately, but I can set something up to show the process.

[@deborapowell8653]

What kind of tape is on the wood?

[@whiskyrivercustomwoodworki2012]

It is sheathing/house wrap tape. Tuck Tape is the brand I like to use, but all of the brands out there work just as well.

[@TheBradtri]

What is your preferred way to remove the hot glue dam after the epoxy has cured? I started sanding first and the hot glue turned into a big messy smear. I switched to using a chisel to pry up the hot glue but wondered if there was a better way?

[@whiskyrivercustomwoodworki2012]

I use a sharp chisel to remove as much as I can afterwards. That’s the small downfall to the hot glue. The other thing I’ve used is a metal putty knife and I sharpen the edge of it. That works well because usually it won’t cut into the wood and it’s flexible.

[@TheBradtri]

@@whiskyrivercustomwoodworki2012 thanks. I’ve also seen folks that use a latex caulk for their dams so I might experiment with it to see if it’s easier to remove.

[@whiskyrivercustomwoodworki2012]

@@TheBradtri I’ve used clear silicone also. Downfall with caulk is the set up time. From what I’ve found removing it is a little easier in some scenarios.
