Woodworking

Table Saw Stand

My table saw came from Tim who got it from Doug. I think Doug put together the rolling base for the metal stand. It worked ok, but the wheels were a bit small when I’d try to roll it out into the driveway and my first attempt at dust collection for the table saw never worked that well. I decided to build a new stand from scratch and I took the opportunity to learn some new things along the way.

The first task was to really learn SketchUp. It’s a free 3D modeling tool that is especially popular among woodworkers. As with any tool like this, there is a steep learning curve, but I’ve seen how much it can help people once they get the hang of it. I’m far from an expert but it was handy to visualize the build before getting into it, and it also helped me figure out how much wood I needed to buy. (The colors are just to help differentiate the pieces.) I stopped tweaking the drawing once I got it close and then I modified all the measurements slightly in my head so that I could make better use of the plywood and not have so much waste. Next time, I’ll spend the extra time to make those tweaks in the model because it would be really helpful to take measurements right from the model to figure out where all the dadoes go.

Tim loaned me his dado blades and I used my new custom insert. That setup combined with the track for cutting plywood made quick work of the main pieces

The dadoes made it easy to hold everything in place while I glued and nailed it together. Unfortunately, once I was part way into the assembly, I realized that I had cut one dado 1/2″ off of where it was supposed to be. Also the whole unit wasn’t quite square. The result was that it looked a little goofy and the box that was going to hold the two shelves wasn’t square. Yuck.

I ended up working around the mess. You can easily tell that it was built by a novice, but it functions quite well. There’s a hole cut out under the table saw so the dust falls into the top drawer. Plus, I have lots of storage for push sticks, blades, and jigs.

I put tall sides on the left and the back thinking that I might add some flip up tables on those sides to help support bigger pieces of wood. I’m not sure if/when I’ll get to that, but it was an easy addition to the project in case I decide to do that later.

The whole unit is solid and rolls around very nicely. The wheels are salvaged from my old Park ‘N Move which I don’t need after selling the motorcycle.

I’d be happy to toss this whole thing out for a nicer table saw, but in reality, this saw has been good to me and I think I’m going to have it for quite a while. There are lots of other tools I’d rather have before a new table saw.

PS. I also should have done a better job planning my cuts so that I could have matched the grain on the drawer fronts. I ended up with a huge green blotch in the poplar plywood on that bottom drawer and it very obviously doesn’t match the top drawer.

Table Saw Insert

I never paid much attention to the insert that fits around the blade in my table saw until I tried to install a thick dado set of blades and they didn’t fit into the insert. You can pay $30-50 and buy new ones but yikes, that’s pricey for just the few cuts I wanted to make.

Instead, I pulled out a scrap piece of wood, cut out the exact shape of the opening, cut out a finger hole, drill some screw holes, routed the bottom to make it the right thickness and then mounted it into the table. I clamped a piece of wood over the insert to hold it down and then turned on the blade. I slowly raised the spinning blade up and it cut a perfectly sized hole in the insert. Booyah. Custom table saw insert for free!

You can find lots of great videos on YouTube showing you how to do this but I particularly liked the one from Frank Howarth.

Cutting Plywood

circularsawtrackI usually work alone in the garage so cutting big sheets of plywood or MDF can be a hassle. Running it across the table saw just isn’t an option until I’m dealing with smaller pieces. In the past, I’ve picked out a straight 2×4, clamped it to the plywood, and then used that as a guide for the circular saw. That works pretty well but it can take a long time to get the guide set up in just the right spot.

I finally got around to making a jig to help with this. It’s not complicated and I definitely didn’t invent the idea, but here’s how you make it:
1) Cut off a 3″ by 8 foot slice of your sheet of plywood. Make sure that you’re keeping a factory edge and you mark it. That’s your straight edge.
2) Measure the distance between your circular saw edge and the blade. Add 3″ for your cutoff and then another ~3″ for clamp room. Cut off another slice that wide. That will be the base of your jig.
3) Glue the 3″ strip on top of your base strip. Make sure the factory edge is pointing at the wider side of the base strip. It should be about 2″ from one edge. Add nails to hold it in place while the glue dries.
4) Now make a cut with your circular saw to trim off the extra wood.

You now have a zero-clearance jig to help you rip plywood. If you’re making a cut on the plywood, add a pencial mark on each end of the sheet where you want to cut. Then clamp your jig down so that it is right up against your pencil marks. Run your circular saw, holding it tightly up against the top fence and you’ll get nice straight cut in the right spot.

My typed-out description isn’t great, but there are lots of videos showing how it all works. I recommend Jay Bates’s blog post and video. He gets to it about halfway through the post/video.

The 8 foot length is a bit long when you’re doing 4′ cuts but we’ll see how it goes. Maybe I’ll end up making a second shorter one.

Milling Logs

YouTube is an incredible resource for learning a new hobby (or expanding the horizons of your current hobby.) Case in point: Matt Cremona. He doesn’t just go to the lumber yard to buy wood for his projects. He walks through the woods, cuts down a tree, slabs it with a chainsaw mill, lets it dry and then takes it into his shop to finish milling it for a project. While this isn’t something that I’ll probably ever get to do, it’s really fun to see how it works. Check out this video demonstrating his chainsaw mill:

Table Saw Rehab

deltatablesawWhile I’m thankful to Tim for the good deal he gave me on his old table saw, I was never a huge fan of it. But some changes I’ve made to it over the past 6 months have made it one of my favorite tools in my shop:

  • The dust collection system that I built does a great job at trapping saw dust. Unfortunately since it sits far away from my shop vac, I rarely have it hooked up. When the box gets full, I have to pull one end off to suck all the dust out. I think I’m going to rebuild this to be just a box with a drawer that I can pull out. Still, this works way better than having nothing.
  • I waxed the top of the table saw. After I was done, I was shocked at how much easier wood slid across the blade.
  • I bought a new blade! I don’t know how old/dull that other one was. I probably could have had it sharpened but I decided to start fresh and then keep it maintained.
  • I adjusted the measuring guage on the fence. It was always off by enough that I had to measure with a tape measure to make sure it was set properly. Now it’s EXACTLY right and I can skip the tape measure.
  • I got a good set of push blocks for Christmas which make it a lot safer to use.

The saw is pretty much still the same as it always was, but these cheap tweaks have made a huge improvement in its usefulness.

Jewelry Box

Four years ago, I decided I was going to make Tyla a jewelry box, but after reading through the plans, I felt like it was way over my head. I got the bug again recently, found some plans, and this time I decided it would be a big stretch of my skills but probably within reach. (Turns out, I was looking at the same set of plans both times!)

There were so many first for me in this project: first time buying walnut, first time buying wood milled only on three sides, first time using a planer to thin the wood down, first time cutting dadoes and rabbets, etc etc etc. I started off with two hunks of walnut and ended up with a jewelry box that looks much better than I expected it to. All those “firsts” took a tool on the schedule though with the project taking 43 days from the time I picked up the wood until the time I finished though of course I wasn’t working on it even close to full time.

In the past I’ve always done bigger projects that went together with screws and nails. This one is held together with only glue and the cuts I made in the wood. It was really nice working this way because you can dry fit everything and have it stay assembled while you look at it. It was also a lot of fun to work with the walnut. When I work with pine, it’s so soft that it dents easily and it’s hard to get precise cuts. But with the walnut, I could get a piece that was exactly the right dimensions in all three axes.

The drawers and the backs of the door and the box are lined with velvet. There are 4 hooks on the inside of the door and four in the back of the box. There’s also a padded velvet ring bar at a 45 degree angle in the box. You can’t see it in the photos, but that ring bar has horizontal slits in it to hold rings in place.

I’m glad that I attempted this project and that it turned out so well, but I’m also happy that it’s over. I want to queue up a couple easy projects to relax a bit.

Saw Blades

diablosawbladeNow that I finally have a shiny new saw, I decided that I started wondering how my old table saw would work if it had a nice new blade on it. Maybe I could get the old blade sharpened, but I kind of just want to start with a new blade and then take care of it properly from the beginning.

I started reading about saw blades and WOW, there are a lot of things to know about the blades. There are different diameters, different blade shapes, different angles for the teeth, different numbers of teeth, different thicknesses for the blade and the list goes on. This article from Rockler is one of the best ones I found for summarizing all the info but here is a quick summary of what I learned:

  • My table saw and my circular saw use the same diameter blade so I can buy one blade and use it either place.
  • Miter saws should generally have a higher tooth count since you are mostly doing cross cuts (~60-80 teeth) while table saw blades should have a lower tooth count since you are mostly doing rip cuts (~24-40 teeth.)
  • If you have less than a three horsepower motor, consider using a thin kerf (thickness) blade. The tradeoff is that the blade might deflect more, but since you are removing less wood, your motor can power through the cuts easier. You’re also generating less dust!
  • Most saw blades have a positive angle to the teeth meaning that they lean forward. Miter saws benefit from a slightly negative tooth angle. This gives you a more controllable cut and also helps to prevent the saw blade from pulling the back side of your wood up into the air.

The saw blade that came on my miter saw is probably better suited for my table saw so I’m hoping to move that over and then buy a higher tooth count blade for my miter saw.

Tool Safety

safetyfirstcartoonA wood shop can be a dangerous place. There are blades spinning and cutting all over the place. One key part of staying safe is knowing what can be dangerous. A 2011 study from the National Electronic Injury Surveillance System lists these as the top injuries:

  1. Table Saw: 39,750 annual injuries
  2. Jointers, planers, shapers, and sanders: 10,930 annual injuries
  3. Miter Saw: 6800 annual injuries
  4. Band Saw: 3550 annual injuries
  5. Radial Arm Saw: 350 annual injuries

Now obviously these numbers are a bit skewed by which tools people use the most often. For example, the radial arm saw isn’t very popular anymore as people are using table saws with sleds for many of the same purposes.

Whenever I get a new tool, I like to do a bit of reading about common injuries and tips for staying safe. One thing I learned with this new sliding miter saw is that after making the cut, you should let the blade stop spinning before lifting it out of the wood. Otherwise you run the risk the cutoff piece catching the blade and flying around the room. It can also give you a cleaner cut since the spinning teeth only touch the wood once.

It’s also important to keep the wood clamped down when possible. When the blade in a miter saw goes through the wood, it pulls up on the back side. It’s not uncommon for it to catch on the wood and rip it up in the air. If the wood isn’t firmly held in place, this can be pretty bad news.

As someone who makes money with his fingers, these kinds of tips are extra important!

Cut List Generator

cutlistOne challenge with woodworking projects is figuring how to make the best use of the wood you have available. If you’re working with expensive wood, your decisions can have a dramatic impact on the total cost of your project. I did some quick searching around and found a few solutions, but my favorite (free) one so far is the Free Online Panel Cut Optimizer.

For the Adirondack chair project, I thought it took two 2″x6″x8′ boards and four 2″x8″x8′ boards. Using this tool, I got it down to three 2″x6″x8′ and two 2″x8″x8′. That drops the price by about 20-25%!

The downside is that the cuts aren’t as simple to make. The way I had it originally drawn, I cross cut the wood and then ripped it to the right width. This more efficient use of the wood requires more strategic cuts, but if it saves enough money, it’s worth the effort.

Dust Collection Update

About two months ago, I picked up a Dust Deputy and attached it to my shop vac to help control dust while woodworking. I let the 5 gallon bucket under the cyclone fill up completely before emptying it the first time and you see the results below. The bucket is mostly full and the shop vac has almost no trace of dust in it! I did take the filter off anyway and blow it with compressed air to clean it anyway, but it didn’t need it. If I had sucked up this much sawdust without the Dust Deputy, I would have easily gone through two shop vac filters and those things aren’t cheap. I’m very happy with this setup!
