Sharp spokeshave blades are a common problem for most bikers. During a bike ride, these spokeshave blades can become extremely sharp, so they should be sharpened regularly to prevent any injury. Sharpened spokeshave blades should be angled away from the user. Bevelled edge spokeshaves should have no more than a 30deg angle. Sharpening a spokeshave is simple if you follow a few basic steps.
Skewing a spokeshave reduces the blade’s angle of attack
Some spokeshaves chatter during certain cuts. By skewing a spokeshave, you can lower the angle of attack and usually achieve a cleaner cut. This technique also helps combat end-grain resistance. Listed below are some tips for skewing a spokeshave. Read on to learn more. This tip will help you get the most out of your spokeshave.
When skewing a spokeshave, you’re cutting at a shallower angle than the blade would be at if it were flat. This reduces the angle of attack so that the wood can more easily climb the blade. This technique is useful when planning end grain, since the angle of attack is lower and the bevel and relief are the same. It may be necessary to hone a low-angle plane to avoid a delicate edge.
When skewing a spokeshave, be sure to use it in the direction of the grain. This will prevent the blade from chattering or tearing out. The angle of attack will also result in a cleaner cut. You may want to use a scraper after sanding the bottom of the curve to smooth out the tangency point. If you have ever seen a spokeshave skewened, you know the process.
As long as the spokeshave has a depth adjustment knob, you can easily skew it to the proper angle of attack. When using a spokeshave without a depth adjustment knob, however, you have to apply a different technique. Start by placing the spokeshave flatly on a flat surface and bottoming it out. You need to tighten it just right without overstretching the blade’s profile.
Reducing resistance on end-grain
Speaking of tools, there’s a great way to reduce end-grain spokeshave resistance by skewing the blade. This technique lowers the angle of attack, which usually produces a cleaner cut and helps you avoid the chattering associated with end-grain resistance. You can also use a scraper to smooth out the tangency point at the bottom of a curve. If you’re unsure which shave to use, consider using a spokeshave with a round-bottom blade.
A spokeshave’s cutting angle is critical. The bevel-up type has a low-angle cutting angle, and it excels at rapidly removing stock from woods with a straight grain. On the other hand, bevel-up shaves can easily tear away areas of reversing grain. To reduce resistance on end-grain spokeshave, you should look for a bevel down #151 type.
The spokeshave’s blade should contact the body at the cap screw and small dark spots. You should also make sure that the spokeshave’s bed is level to prevent any ridges from occurring. Make sure that the spokeshave’s blade is not too long or too short; the length of the spokeshave should match the length of the wheel. If the spokeshave doesn’t fit properly, sand the spokeshave to remove any excess.
Construction of a simple sharpening jig
The construction of a knife sharpening jig is simple and affordable, and can be built on a project table or small workbench. A short eight-step tutorial explains how to build a jig for knives. Once you have all the materials, it’s time to install the jig and start sharpening your knives! Once you have the knife and the jig installed, you’re ready to place it in the jig!
The jig will need a side and a distance block. The side will act as a guide to keep the blades at the proper 90-degree angle. You can make a small wedge to use as the distance block. Once installed, install the two T-nuts on the end of the dowel. The T-nuts should be installed so that the wood portion of the dowel does not reveal any metal. Metal can affect the sharpening process.
A commercially available jig can cost $50 or more. Fortunately, a simple jig design can save you money. It’s quick, easy, and doesn’t require welding or special tools. The only downside to a home-built jig is that it requires a great deal of time, but the results will far outweigh the investment! And since it’s not difficult to make, you’ll be sharpening knives without breaking your wallet.
A four-facet jig has four facets that work together to provide optimal sharpening. One facet extends into the center of the drill, while the other two are extended beyond it. The point splitter extends forward from the center of the drill face, making it easier to see the drilling action and minimize the tendency to wander. By making the face a symmetrical shape, the drill is sharper than ever before.
Practice makes perfect
There are a few basic steps in sharpening a spokeshave. First, prime the spokeshave blade with the sharpening compound and hold it with your fingertips toward the end of the spokeshave. Roughly move the blade back and forth on the first stone until you reach a 25 degree angle on the blade. Repeat this procedure for the second stone. After that, you can begin sharpening the blade as needed.
The spokeshave is a difficult tool to master. Practice makes perfect when it comes to sharpening this tool. To make sure that you don’t ruin your spokeshave, use two different strokes: one to push down the blade, the other to pull it up. It’s better to use the pull stroke if you feel like you have more control. After practicing a few strokes, you can then adjust the angle of the cutter.
Once you’ve sharpened the blade, you’ll need to refine the cap iron. This is a vital step in sharpening spokeshave blades. If you use too much of this part, the spokeshave will not work well. You can use auto-body compound or Bondo to make the cap iron sharper. Be sure to use wax to protect the blade from sticking. Once the spokeshave blade has been properly sharpened, you can tighten the cap screw to apply even pressure to the blade. Then, remove the squeeze-out by using a sharp knife and file.
The process is the same for both antique and modern spokeshave blades. The difference is in the level of flatness of the cutting edge. If you want to achieve this, you need to flatten the surface of the blade by lapping. You can use a commercial stone or shop-made blocks for this purpose. Use downward pressure on the face of the blade while pushing the edge of the spokeshave into the grit. Remember that a low-angle spokeshave blade feels longer than one with a high-angle bevel.
Safety precautions to take
There are a few safety precautions you need to keep in mind when sharpening a spokeshave. This tool is made of metal and has a number of sharp parts. To avoid injury, wear eye protection and safety clothing when sharpening it. Also, take care when handling the spokeshave. Failing to loosen or overtighten the tool’s parts can damage the blade, so be very careful.
The spokeshave is an extremely large and heavy piece of equipment, so it’s important to use safety precautions when sharpening it. The cutting iron’s depth should be adjusted using the two adjusters. You can also sight the cutting edge against the spokeshave’s sole to determine the proper depth. You can also perform a wood shaving test by cutting a thin piece of wood with the same amount of pressure on both sides of the blade.
To properly adjust the depth of a spokeshave, start by making sure it’s flat and level. Some shaves come with the sole machined, so all you need to do is smooth it out a bit with emery paper. If your spokeshave doesn’t have a depth adjustment knob, use an emery sheet on a glass. If you have a round-sole spokeshave, use emery paper on a scrap piece to smooth the edges. This also prevents irregularities around the mouth of the spokeshave.
Before sharpening a spokeshave, make sure the blade is properly seated in the spokeshave. It should be protruding below the spokeshave’s sole by a thickness of about half a human hair. The blade should also extend evenly across the spokeshave’s opening. If you’re sharpening a spokeshave by hand, make sure the ramp’s surface is level and clean.
