I had to edit this blog and change the title, because I did identify the wood I have as Ipe. Ipe or Brazilian walnut is a popular high end exterior decking lumber. Mine came from from Brazil and according to Wooddatabase.com ( http://www.wood-database.com/lumber-identification/hardwoods/ipe/ ), Ipe was moved from the Tabebuia genus, listed as a spiecies of ironwood ( https://en.wikipedia.org/wiki/Ironwood ) to the Handroanthus genus, which is not on that list, in 2007. This is news to me, but I do not want to give bad information.
Last weekend, I constructed the shell of the first cabinet on the list of furniture that I am building for my wife.
Ready for drawers!
This weekend I worked on drawers. Working around the bad, I cut the pieces for the drawers out of reclaimed lumber. I did not get the drawers together but I did finish building drawer glides and that is the subject of this post.
I am not sure of the specific tree, because there are a bunch, but I have some ironwood 2×8 decking planks. I think they are Ipe but they could have come from Malaysia. These boards are clean, clear, straight, flat, dense and very hard, the perfect material for drawer glides. I should note that I wore a mask and ran my air filter while I was working with the ironwood. The dust is very fine and it can make one sick when not used to dealing with it.
While it made a great cut, it bothered me. A saw with no attached dust collection, equipped with expensive negative rake blades, and a tendency to dig in to dense materials and jump forward, may not be the best choice for cutting ironwood.
The slider was a much better choice. I set the drops aside to cut out knobs and totes for 3 needy bench planes and went to the table saw to cut out the rest of my pieces. I sawed out 12, 2 1/8×5/8×17 1/4 inch pieces and 12, 2 1/8×19 1/4 inch pieces. I needed each one of these sticks to be perfectly flat, square and exactly the same size as the others. My table saw and planer handle it fine but when I face ironwood with my jointer, I take shallow passes because it wants to bounce and drift towards the cut, which can take it away from the fence, exposing the cutter head.
Next it was time to cut some rabbits and dados. I cut a couple of test pieces to help with this process. Check out the difference in density between ironwood and pine!
I usually use a steel stacked dado set in my table saw, but for the ironwood, I used the carbide set that I run on my radial arm saw. I do not usually try to cut a large number of small dados in ironwood with my router. Iron wood is high in silica, very dense, and it can be hard on my small straight bits.
I used a small shoulder plane, chisels, a mill file, and a scraper to fit the 2 parts of each slide. I was very careful because the drawers should rest on both bearing surfaces of the double glides.
I think they are way cooler than metal glides and the drawers will work way better than if I had just rested them on top of pine bearing strips. (My wife expects drawers to work flawlessly.) Ironwood is very stable so I can get away with tighter tolerances than if building glides out of softer material. Once finished, the pieces should not swell together and trap the wife’s cooking utensils…hopefully. It is also very strong and the glides should hold the drawers up no matter what we put in them. When the oil soaks in, the dadoed half will be recessed into the drawer sides and fastened with screws, the rabbeted half will be fastened to the wall of the cabinet. Before I put them together, I will sand and wax the bearing surfaces. There will not be any rails between the drawers.
