Topic tags/keywords: question tip trick

hi all

I have a 36”diam soft maple slab.It has been air drying for about 4 yrs from what i have been told. I plan to turn it into a coffee table for someone, who gave me an old lathe (that is another blog). My plan was to use hand tools to build this table but after putting a straight edge on it I realized that I had to remove about on inch to get it flat. So I gave up on that idea and went for the power tools. After alot of thought I came up with what I thought would work for me. Basically I use some parallel beams and a sled for my router. It came out surprisenly flat. but left a lot of deep srachtes so i reached for my belt sander. After doing some clean up I now see several small cracks. I am will to put in some dutch men but I don’t want a dozen or so of them. So hear is the question, can i use CA glue to stableize the cracks? they are all small and fairlly thight. Biggest one is maybe 2in long and 1/64 wide. Any help would be greatly appreciated

thanks mike h
ps sorry for any spelling errors, I think I am better with wood than letters

Is the slab a cross-section or along the grain slab? CA might be too inflexible to movement, possibly a sawdust/glue slurry? Not sure how to obscure the repairs though, since odds are you’ll be clearcoating the finished piece.

I don’t think CA will stabilize the cracks ,Some times you can drill small holes at the stopping point of the cracks and fill them with wood filler to hide them. I would also check the moisture of your wood before going any further.

thank you for your responses. the slab is a cross section. no moisture meter at this time. it has been in my shop for about a month. I did not see any cracks at first. could i have removed wood to fast? took off about an inch in two days.

thank you again mikeh

Hey Mike
The Cracks are probably tension cracks ,trees have stress on them like limbs holding them a certain way and then there cut and the tree is milled wood straitens up and it has internal cracks .You can still drill little holes on each end to help stop the cracks from expanding. The holes don’t have to be really big 1/32 for small cracks will do it. If wood has this internal tension it can create lots of problem with you project,it can also pinch your blade on you table saw when you cutting it an create dangerous kick back. Its a very good idea to have your blade guard and splitter on.
I know your a seasoned woodworker mike but I thought I’d include this for less experienced folks.

I know buying a moisture meter may not be high up on your list of want to buy list but if you are buying a decent amount of wood, it’s a must have. Buy a good one. Don’t waste you money on a cheap one. Plan to spend at least $100.

“Has been air-drying” does not mean dry. How thick is the slab? I would go along with Jim’s post about moisture. If you did not see the cracks before but they are appearing now, your wood is not dry and it’s drying to fast inside your shop.
