Recently, I learned a few things with woodworking. One project I did was a handle for a file. Here are some photos and a few words describing the process I used for the final product, which you can see in the first photo.
The small grip notches sawed into the corners are stained with ebony polyurethane. The rest is coated with clear coat poly. This next picture is of the file from Home Depot and the block of wood I used for the handle. You can see the guidelines I drew on the handle with a .7 mm gel pen. The file itself is a nice one and worked great for what I needed it for, even came with a lifetime warranty. I used the pen lines for sawing out the grooves with a hand saw and also used the saw to make some small grip marks.
The photo below shows the file and the handle after I sawed the block of wood and before I sanded it.
This next photo shows the handle after it was sanded with a course sand paper a few times and then a finer grit sand paper afterwards.

After I took the photo above, I put the handle in a jar full of polyurethane with it wired to a weight. I customized the lid of the jar to hook up a break bleeder to it which uses a pressure gauge. Every six hours or so, I increased the vacuum to 17 pounds, for a day or two. The air leaked, gradually, however it was an attempt to stabilize the wood with poly. I let the handle sit in the jar under the vacuum for five days, even though it was not really under much pressure due to a slightly leaking seal.
The wood soaked in the poly, nevertheless. I removed the handle from the poly and wiped it clean with a napkin. I then cleaned out the hole for the file. I baked it at 200° f for an hour, letting out the air every ten minutes or so. I let it cool and sanded it with a course grit paper to remove the heat bubbles. I could tell that not too much polyurethane soaked into the wood, which is the hole point of stabilizing it, so it will last longer. While under vacuum, I did see bubbles come out of the wood, which means it was at least partially stabilized.
After I sanded it well to remove the heat bubbles, I could see that the poly did not fully penetrate the wood. The harder a wood is the more difficult it can be to stabilize it; I do not yet have a vacuum pump which runs off an electric motor, which may have been able to produce a stronger vacuum. I do have a pump of such a nature on the way, however I think my efforts with the file handle have come to a satisfactory conclusion.
I sanded it once more with a finer grit sand paper to get it smooth and coated it with clear coat polyurethane one last time. It came out smooth and glossy and is nice enough for me. Here is a larger photo of the final product.
Thank you for reading this post; I hope you enjoyed the photos. This was a fun project and I cannot wait to learn more with woodworking. There are plenty of different wood hardeners and stabilizers out there, as well as many kinds of wood, some of it soft enough for proper stabilization. If I ever make a small wooden car or Christmas ornament, I will be sure to post some photos of those projects here on jcm3blog. Thank you for reading; we always appreciate your feedback. 🙂
