5 Methods to Create Precise Rabbet Cuts
Posted on Monday, January 18th, 2016 at 1:12 pm.
Here are 5 tried & true methods to creating the most precise Rabbet cuts! Rabbets can be cut with a table saw (set up with a dado set or combination blade), router (handheld or table mounted), or jointer. The choice depends on the type and quantity of work-pieces, and the desired quality of rabbet cut. (This except is taken from Wood Magazine 2011 edition)
** A rabbet is simply a rectangular recess along the edge or end of a work-piece. Although most often found as a joint in casework), a rabbet also can pop up as a design feature in a molding, as a recess for holding artwork in a picture frame, along the edges of a cabinet door to help recess it partway into its face frame, or as a half-lap or ship-lap joint.**
1. Table saw with a dado set: We use this setup often because it yields clean rabbets in one pass typically-two passes for wide rabbets. For good results, you need a high-quality dado set. Since it takes a little time to install the dado blades, we use this method only if we have several work-pieces to cut.
- Attach a 3/4″ wooden face to your table saw fence. By doing this you can cut into the wooden face and fine-tune the width of the rabbet with quick fence adjustments.
2. Table saw with standard blade: If we’re rabbeting just a piece or two, we’ll leave our combination blade in the table saw and make the cut in two passes. The key: You need to precisely set the fence, and the height of the blade, for both cuts so one doesn’t cut beyond the other.
- Cut the rabbet to its correct depth with the work-piece face down on the tabletop. Then, stand the piece on edge to cut the rabbet to width.
- If you don’t own a good dado set, or have a low-powered saw, this option may prove better than No. 1 for all of your work. But, it can be tricky if you need to rabbet the end of a narrow workpiece. In that case, you will need to clamp the work-piece to a fixture that holds it steady and upright as you guide it along the fence.
3. Handheld router with rabbeting bit. Unlike saw blades and dado sets, router bits do not leave tiny scoring marks. So, use a router bit if the surface or ends of the rabbets will be visible in your finished project.
- Router bits are your only option if you need to rabbet an opening inside a surface rather than along an outside edge or end. Examples include a router-table opening for receiving a router plate, or the inside of an assembled door frame for accepting a piece of glass.
-
With a handheld router you typically use a rabbeting bit with a pilot bearing as shown above. You can change the width of the cut simply by changing bearings. And, with this setup you can even cut rabbets along curved edges.
4. Router table with a straight bit. Although you can’t easily rabbet large pieces on a router table, this method has some distinct advantages over a handheld router. First, a router table has a fence that ensures a perfectly straight rabbet (a bearing-piloted bit will follow any irregularities in the work-piece edge). And, although a piloted rabbeting bit will help you cut a rabbet up to 1/2″ wide and 1/2″ deep, you can put a large straight bit in a router table and cut rabbets up to 1X1″.
5. Jointer: We admit we rarely use a jointer to cut rabbets, but if you must cut a perfectly smooth rabbet over 1″ wide, and along a straight, outside edge, look to a jointer. You can cut a rabbet as wide as the length of your jointer’s cutterhead. The maximum cutting depth of your jointer will limit the depth of the rabbet, typically to 1/2″.
- To do this, you need to make an initial cut with your table saw. First, set the blade height to match the depth of the rabbet. Adjust the fence-to-outside-of-blade distance to match the rabbet width. As shown, this cut will prevent the end of the jointer’s knives from hammering the work-piece. Remove no more than 1/8″ with each jointer pass.
Using these tips and tricks should help you to be successful in cutting the cleanest & smoothest rabbet cuts!

About Whiteside-
For over 40 Years, Whiteside has consistently produced superior cutting tools, which has given them a name recognized for quality and dependability. American Made Whiteside router bits typically rate number one for both quality and value in Magazine reviews. These top end router bits are beautifully balanced and prevent ‘potato chipping’. Whiteside uses thick pieces of high quality micro grain carbide so that it keeps a sharp edge and can withstand extra sharpening. Held to strict tolerances, you will never have to worry about consistency in cuts and performance. Read our previous article on the beginning-to-end process of the life of a Whiteside router bit.
Don’t just take our word for it, click here to read Brian Kent’s review from Sawmill Creek! He was on the look-out for an American Made router bit to create a custom high-chair for his grandson. After doing research he narrowed his choice done to 2 types of Whiteside router bits: bowl and tray & round nose core box bit. Unsure of his decision he posted his dilemma on Sawmill Creek.
That’s when we stepped in and offered to contact Chris at Whiteside for his recommendation. He recommended the Whiteside 1376B and 1411 for this special project. Tom saw this as a wonderful opportunity for a Tool-Review so we offered to send him both bits for free if he would let us know how they performed.

Woodworking Hazards- Common Issues & Preventions
Posted on Thursday, October 8th, 2015 at 2:39 pm.
Wood is the most commonly used material for arts, crafts, jewelry, woodworking, framing, joining, sawing, sanding & painting. Here are a few safety considerations to consider before embarking on your next project.
Hardwoods – used mainly for sculptures and furniture making.
1. Direct contact from sap found in most green wood can cause skin allergies & irritations.
2. Long term dust exposure can cause conjunctivitis, hay fever, asthma and other respiratory diseases.
3. Some hardwoods contain toxic chemicals that can cause headaches, nausea and irregular heartbeat.
Softwoods- common in furniture making.
1. Dust exposure may cause respiratory inflammation.
2. Some individuals can develop allergic reactions involving skin irritations.
Plywood and Composition Board–
1. Formaldehyde is toxic by ingestion and skin contact.
2. Machining, sanding or heating can cause formaldehyde to become airborne.
Wood Treatments & Preservatives–
1. Certain chemicals are highly toxic and can be absorbed through the skin causing organ damage.
2. Inhalation may cause digestive problems as well as kidney and blood damage.
Gluing Wood–
1. Epoxy glues are toxic and should not come into contact with skin, eyes or inhalation.
2. Cyanoacrylate glues can glue skin and other materials together requiring surgical separation.
3. Formaldehyde-resin glues are carcinogens.
4. Adhesives are extremely flammable and cause nerve damage when inhaled.
5. Water based glue is slightly toxic when ingested or inhaled.
Paint Striping–
1. Toxic when inhaled or makes contact with the skin.
2. The solvents used are highly flammable.
3. Caustic soda used is highly corrosive to human skin and eyes.
Painting & Finishing–
1. Mixing paint from dry pigment can lead to possible inhalation.
2. Solvent based paints are flammable.
3. Water based paint does contain some solvents but is of minimal risk.
4. Shellac usually contains ethyl alcohol which is slightly toxic but lacquers are made up of toluene & hexane.
5. Paints, waxes & polyurethane coatings based on mineral spirits are combustible.
6. Oil soaked rags and paper towels are a spontaneous combustion hazard.
Preventive measures should always be used to maintain your safety. Wear the proper safety gear as in safety glasses, hearing protection and face shield/mask. Also, know the tools and machines your are working with. Make sure to read manuals and follow recommendations on tool care and RPM’s. Make sure all blades, bits and drills are sharp and in good working condition. Do not use a tool or attachment on a machine for which it is not designed. Always clamp stock securely when sanding, grinding or drilling. If possible, use an exhaust ventilation system to remove sawdust and chips from your machines. Work in a clean well-ventilated area and research the wood and/or chemicals you will be working with. Avoid distractions!
Donation to the Middle School Robotics Team
Posted on Friday, October 2nd, 2015 at 1:28 pm.
Today’s youth is tomorrow’s future. Tom, the owner of Carbide Processors, firmly believes this and is always more than happy to help and invest in our youth.
About a year ago, we had received an email asking for help with supplies and tools for a middle school robotics team. This request was for a group of young kids that had a strong desire to learn and were very interested in robotics and science. Of course we were more than happy to help.
The boys were eager and excited to organize their own robotics team and compete against other kids in the VEX robotics competitions. The mother of one of the students that had originally contacted us shared a letter about the team and the VEX Robotics program below.
“Last year, two of the boys, Ben and Devin, wanted to start a new robotics team in December but they were informed by their school that it was too late in the year to start a new team. They were told that they were still young, 6th graders and 12 years old, and that they could start a new team in the next school year. Well, Santa was kind to them that December and robot parts arrived under the tree. The boys formed a team outside of the formal school system: Team 351A-The Warp Drivers. The boys worked hard and competed as an independent family-supported team. Amazingly, they went on to win the Vex Robotics Maryland State Middle School Championship last year (I guess they weren’t too young to win)! This year the two boys were joined by another friend, William, also a middle school student. The three boys, now seventh graders, have repeated their winning performance in the 2014-2015 Vex Robotics season and have again won Vex Robotics Maryland State Middle School Championship! Two years in a row! Additionally they are #1 in Programming and #1 in Robot Driving in Maryland, middle school division. To watch the team in action, the boys have some of their robot matches posted on their YouTube channel (Vex351A): https://www.youtube.com/channel/UCUMnULnhHnLXjEklvBWy0_g
Needless to say, we are all very proud of our kids!
[We’re pretty proud of these young kids too]
The VEX Robotics program, which is a part of the REC Foundation (http://www.roboticseducation.org/), is an incredible program that fosters STEM in the community, inside and outside of schools. The obvious aspects are engineering and programming but it also teaches kids to present their work to adult judges and to learn to communicate with their peers, since the kids have to figure out how to work together (and against each other!) on the competition field. The 2015 VEX Robotics World Championship Middle School Division information can be found at http://www.robotevents.com/robot-competitions/vex-robotics-competition/re-vrc-15-1983.html. It will be held in Louiseville, Kentucky at the Exposition Center and at the same time, the Elementary, High School, and University divisions will also be running. There will be over 4,000 kids from all over the world competing …. and about a zillion parents and teachers will be present!”
Elizabeth thanked us for our “generous support”, but we were truly grateful and honored to be able to help out such a great program.
The VEX Robotics teams often use hex keys (like the Bondus 5/64″ hex keys, or the Bondhus 3/32″ hex keys) to construct their robots. We had made a donation of hex keys and Edge Eyewear safety glasses to the kids in the VEX program. Thank you Elizabeth for sharing your story and for allowing us to be a part of it.
