“Wondering if you know of a way to break apart joints glued with Gorilla glue. Whoever tried to repair this antique dresser drawer let the glue squeeze out all over and didn’t clamp the joints so one has set up so far apart the drawer won’t fit in the case. I can use a sharp knife to cut out the squeeze out, but how do I get the joints apart? The Gorilla folks say there is no chemical that will break the bond.”
I’m assuming you mean Gorilla’s polyurethane glue, not their wood glue.
It seems like Gorilla Glue would know their own product best, but a little cruising on the web indicates that denatured alcohol or acetone might loosen the hardened glue up. Home centers or paint stores should carry either product. I’d lean toward trying the denatured alcohol first as it’s not as potent as the acetone. If denatured alcohol doesn’t do it, go to the stronger solvent, acetone. In either case, work in a well-ventilated area and be sure to wear the right protective gear.
From what I read it looks like it’s important to allow the solvent to soak in for a while, 10 minutes or so, before trying to remove the glue.
(In reference to Building and Accessorizing a Workbench) Very interesting and informative.
“Why didn’t you drill the bench dog holes with a router and 3/4″ straight bit through the template?”
Great question. I learned the answer the hard way. My first approach was using a plunge router, ¾” straight bit, template guide bushing and the pattern. Unfortunately, with such a deep plunge in hardwood, it’s A LOT of work for the bit, and just didn’t work. Even with drilling out to 5/8” the router bit didn’t like making the plunge. If the bit chatters even a tiny bit the holes lose their tolerance and the bench dogs won’t work.
“In Ontario, Canada I have free fallen trees cut down by the city to walk away with . How long is too long to consider fallen wood to be not green enough for re-sawing?. The trees have been down two winters. What tools & blades will do the job?”
It can take intact trees quite a while to get too dry, but there are lots of “it depends.” The larger the diameter of the tree, the longer it will take to dry. If the bark is still on, the trunk will have dried more slowly. I’ve left logs for a couple years, hoping to get to them later, and once I cut the dried out ends off, they were amazingly wet inside.
To determine if the log is ok, first have a look at the end. It’ll probably be cracked pretty badly. Using a chainsaw cut about 12” off the end. See if the cracks have penetrated to the point where your new cut is. Keep cutting chunks off the end until you get to a point where there aren’t any more cracks. Then use a moisture meter to check the intact wood. Hopefully it’s 25% or higher. You can then start processing the log.
You can rip the log with a chainsaw. It’s best to use a dedicated ripping chain, available from chainsaw suppliers. You can also make the cuts on a bandsaw using the widest blade the saw will handle, 3 TPI (teeth per inch).
Using the search window on WWGOA.com (upper right hand corner) search “logs” and you’ll find quite a bit of info on this topic.
