Phenolic Miter Saw Zero Clearance Insert

My 3D printed zero clearance inserts for the miter saw have not held up well. They don’t react well to heat and I only get a few dozen cuts out of them before cut tears start to appear. The plate has to be 1/4″ thick which makes it difficult to design for. I have used plywood in the past, but that is tough to make work right. I finally broke down and picked up some phenolic sheet. Phenolic is paper impregnated with a hard resin. The result is really stiff and slick.

I started by copying the insert that came with the saw and expanding it a little so it fits tighter in the opening. I made a test piece and when everything turned out ok I wrote the instructions on the master. First cut a piece of phenolic to rough size, attach the master, and trim it down on the router.

Once the shape is cut right I peel the master off and stick down the original saw plate. I use it to transfer the hole locations with a 3/16″ transfer punch. Transfer punches come in handy for just this sort of thing. Next I do a counterbore to give the screw head some place to live, then finally drill through the rest of the way.

The new plate is screwed into place, then I just make the first cut and voila, the zero clearance insert is complete. My first one had seen dozens of cuts without any issues. Hard to say how long these will last, but as hard as the plastic seems, it should be quite a while.

Swiveling Dust Collection Fitting

My dust deputy cart is doing a reasonably good job of helping me keep clean. One place that falls short is the hose that attaches to the inlet of the dust cyclone. The inlet part is tapered and the plastic is quite slick. A picture from my original post shows that I originally held it in place with zip ties. I moved on to a hose clamp, but that didn’t work either. It always gets twisted up during use, and it falls off constantly. I need a connection that can swivel and stay attached.

My solution to this issue is to 3D print a tapered ring with threads (red below). A loose tube butts up against that (yellow), and is held down by a nut (green). I did a cross cut shot to show what it looks like when assembled (lower right). My CAD software introduced a few new colors to confuse the issue.

I had a lot of blue filament lying around so I made everything out of that. The tapered base goes on and screws into place to keep it from falling off. I then screwed on the big nut to capture the 2″ hose adapter. The nut threads interfere heavily, so it won’t move without a lot of effort.

I tightened the nut down enough to form a reasonable seal, but loose enough to let it swivel. To connect the hose to the swivel section I again used a hose clamp. This time I printed and glued on a little handle so you don’t need a tool to loosen or tighten the clamp. Ask me in 3 months if I like it or not.

Rolling Sink Carts

Now that my summer slog rock project is done, things have cooled down enough to get back into the shop. I am still refining the organization of my shop and turned my attention to the area around my sink. There was a pile of spray bottles and gallon jugs of cleaners scattered all over the place. I wanted to make a little set of carts that slide out to hold the junk.

The two carts sit low on either side of the sink and roll out to expose all their contents. These are already mostly full which means I either made them too small or I need to pair down the stuff I keep around.


I designed this project back in the spring based on a gallon jug of headlight fluid and two scraps of plywood I had. Thankfully 6 months later the jug was still the same size and the plywood was still there. The design is like a two shelf book case, only with no back. I made runners to go on either side of the shelf to prevent sag and keep everything from racking.

The assembly was mostly glue and brad nails, and once dry felt quite stiff. I gave everything a single heavy coat of polyurethane. I would typically use boiled linseed oil for shop furniture, but had some old urethane around and figured these would get splashed around the sink quite often.

I found really small wheels to put on the bottom. They don’t swivel, but I don’t need them to. The carts just roll in and out. Plus their compact size means I waste as little space as possible. Lastly I printed a beefy handle on top to help me grab and roll the loaded carts.

Straight Edge Clamp Saw Guide

Track saws are one of the hot new things in woodworking. I guess they have been around for a while, but it seems like every power tool company has jumped on the bandwagon. They look handy and appear perform nice clean cuts with the way the track backs the saw blade. They are all really expensive though.

A cheap substitute is to use a clamped straight edge to run your saw or router up against. It works, but doesn’t prevent you from wondering away from the guide and doesn’t back the cut. I have a few clamping straight edges from a company called E Emerson. They sell a saw plate to attach your own circular saw to their track, but it has abysmal reviews and doesn’t back up any of the cuts.

Instead I am going to 3D print an adapter to hold a sheet of 1/2″ plywood to act as a moving saw plate base. I took a pile of measurements and after a few iterations came up with the right design that would hug the tracks available on the clamp.

I had some phenolic faced plywood left over from making my own table saw inserts. I cut the plywood to the rough size of my circular saw base, and attached two long guides.

To attach the saw, I tried printing some different bracket styles, but was never happy with how they held. Instead I found a 1/4″-20 threaded hole in the base near the front to take advantage of (I think it was for some kind of moveable crosscut guide you could buy), and just drilled a hole in the back. It worked out though, the ribbing in the saw plate holds a nut perfectly. I counterbored holes in the bottom to keep the screw heads from interfering with the plate’s movement.

The saw is well fixed now and ready for me to plunge the blade through. With this setup I cut a slot that is perfectly sized for the blade. Now any cutting I do will be well supported and have little to no tear out. It is like a moving zero clearance insert.

It just so happens that I had a full sized sheet of plywood that required crosscutting down to reasonable sized for a project. Here is the setup ready for its first cut.

Everything went smoothly until I got to the end. The guides got hung up on the folding clamp lever (blue and pointing downward in this picture). It left me with a few extra inches of plywood still left un-sawed. Kind of a bummer.

I regrouped and decided to move the front guide back until it touched the rear one, this would buy me a little. It still wasn’t quite enough, and some heavy sanding was required. Once I shaved it down at an angle I was able to make a complete cut across the plywood.


Once I got the cutting part figured out I wanted a set of guides. Setting up one of these straight edges always involves a bit of math. You need to know the distance from the blade to the edge of the saw plate, and are you concerned about the inside or outside edge of the saw kerf? I made a set of plywood blanks that show exactly where your cut will land. Now you can make a mark. line the blanks up, and voila. Just line it up and that is where the cut will happen.

I made a number of different length guides all designed for 1/2″ plywood and uploaded them to thingiverse.

Cutting Board Wedding Gift

I am about 6 months late on this wedding gift, but better late than never! I wouldn’t normally add yet another post to the internet about making a butcher block cutting board, but this one had a few noteworthy mistakes I thought I would share along with a juice groove, which is a novel endeavor for me. Isn’t it funny how cutting boards call for half the clamps in your shop?

Lesson 1: Melamine Does Not Resist Glue

I had some spare plywood with melamine face that I thought would make a good glue up surface. It is flat and strong and the wood glue will not stick to it. Imagine my surprise when the board wouldn’t come off. I employed numerous wedges and was eventually able to break it free. I don’t know what they use to hold the face down, but my glue is better. I guess you need to wax it to prevent adhesion. I will go back to using wax paper like I did before.

Lesson 2: Helical Cutters Work Wonders

On a more positive note after scraping off the glue ridges I tried to send the board through the planer. Normally using a planer on end grain like this yields poor results. I had it shoot the board out of my last planer in pieces. My new helical cutter works wonders, the top looks gorgeous now.

Lesson 3: Watch Your Glue Up

I thought I was being really careful with this build. I measured and planned everything out so there was a 1:2:3 pattern to the size of the blocks in the board. That worked out, but I failed to flip the last piece properly when gluing. The pattern repeats on that last row.

Lesson 4: Juice Groove

I cut the last row off and re-sanded the end. Despite some minor road bumps this was going well. Time to press my luck even further and add a whole new feature! There are a lot of ways of doing a juice groove. Setting up stop blocks on the router table seemed to be quick, safe, and reliable.

I used that row that was cut off to experiment. You have to use a lot of pressure up against the fence or else the bit will wonder. Ok, now on to the real thing.

It was quick, it was safe, and it is certainly a groove. Not 100% reliable though. It looks straight everywhere, but overshoot exists at some corners. I don’t know if the stops shifted, or if my measurements were just off. Maybe I won’t be using this technique any more.

The Finish

Over all I would call the board a success. It came out slightly smaller than intended and the juice groove has a little wonder to it. Otherwise the oiling process made me very happy I with my efforts.

I kept pooling mineral oil on the top surface and let it soak in. That juice groove kept the oil from spilling over the edges. Eventually it saturated through all the way to the bottom side.

Bandsaw Outfeed Table

I have a project coming up that will require a long resaw cut on my band saw. Resawing is where you sit a board up on its skinny side and cut down the length. I love my bandsaw, but when it comes to doing long work the small table has left me in the lurch. The bandsaw is a tall tool so that most roller type outfeed supports don’t come close to high enough. I am going to add a removable outfeed table to the back end to help with these kinds of scenarios.

I have some phonelic resin covered plywood that makes good slick surfaces for things like this. The resin surface can chip off if hit on the edges though. I made a frame to hold the plywood, protect the edges, and give me a place to bolt too. This could have been done in pine, but I am trying to increase the quality of my infrastructure work, so I went with maple instead. I routed a groove on the router table and used my roundover templates to make the corners match on the plywood insert.

After gluing and pinning it through the side I did a careful trim with a block plane to get the outside frame and inside surface to be perfectly flush. This made fun little corkscrew shaped shavings. Now anything sliding across wouldn’t get caught on a lip or edge, and the sides of the plywood will remain protected. This is another place where hand tools make the job a lot safer and less likely to induce disasters than something with a motor would do.

With the table top complete I needed a support leg to help keep the back end from sagging. Making it screw together let me turn two short pieces of plywood into a longer one, and helped with fine tuning the outfeed level.

A hinge attaches the support leg to the under side of the table top. There was a good place for the bottom of the foot where the bandsaw base meets the cabinet it sits on. This will let the table support a decent amount of weight without sagging.

The bandsaw’s table top has two bolt holes in the back that accept M6 screws. I got some socket head cap screws and bolted the front of the outfeed into the back of the cast iron top. The back support leg keeps the rest of the table top up under load. I finished everything with boiled lineseed oil and wax.

The table is almost exactly the same width as the iron top, but doubles the total length. Now I can resaw a 3ft board without worry about it dropping off the back end. As a bonus, the outfeed table doesn’t interfere with anything behind it when pushed into its resting place. Nor does it interfere with the fence. Basically I will probably never take this off.

April 2019 Prints

RTIC Tumbler Handle

For some reason RTIC has changed the shape of their 30oz tumbler. Not sure if YETI did this, and they followed suit or what. I suspect it is a plot to sell more handles and accessories. As it stands, the old handle I designed doesn’t fit on the new style of cup any more. The taper angle and diameters are just a little different.

My old handle was printed in 2 parts because most low end printers (including the one I owned at the time) couldn’t print something that big. Now a days at least a 6×6 bed size is pretty bog standard. This new design will be all one piece. The cup is large enough in diameter that getting my calipers on it wasn’t going to work. I printed some rings of different diameters and used them to estimate the taper angle of the new cup.

With that figured out I just printed a new handle that looks a lot like the old one, only with slightly more finger room and a longer grip. Thingiverse link

Drawer Pull Centering Jig

I picked up a Kreg cabinet handle jig for one of my recent projects, and because handles are something you install pretty frequently. It is certainly possible to do them well without a jig, but that always makes repetitive work easier. The jig does a good job of setting the height and width of the holes. It doesn’t center them on the drawer though. I made a few add ons to help with that.

I took a length Kreg track that you would normally imbed into a table to make moveable hold downs. Instead, this becomes part of the top fence used to set depth. Now with a spacer it registers across the whole top edge of the drawer. That also lets you use an edge stop. Now it is all centered. Once set you can put handles in the same drawer position over and over again with no more measurements or adjustments. The only downside is that there was a scale on the back of the jig for setting depth. That no longer measures true because this vertical stop doesn’t register where the old one did.

Router bits

Storage and organization is a place where the printer continues to be endlessly helpful. I have had this nice router bit set for years, but always had trouble getting the bits back in their slot. They end up clanking around the drawer and taking up more space than they should. A simple printed tray gives them each a home and takes up a lot less drawer space. For smaller prints like this, a label maker works better than trying to 3D print the text.

More Dust Collection Adapters

Woodworking Dust Collection Rule 1: No two dust collection ports are ever the same size… EVER

Once again I find myself trying to fit a dust collection hose on to some of my tools and wind up having to 3D print a custom solution. Why is it always like this? This time it is a port for my random orbit sander to 1.25″ hose (which isn’t really 1.25″), one for my belt sander, and an adapter to go from that hose to my dust deputy inlet (which has some funky taper on it). The good news is that the ridges left over from 3D printing these always helps the adapter stay in place, even if it isn’t perfect. This is exactly why industry standards and groups like ASME and SAE exist.
