Gift From Bob Claggett

Bob Claggett runs I Like To Make Stuff. He has weekly posts with great projects that are achievable for the common man. Those projects span woodworking, electronics, 3D printing, model making, and much more. It’s one of my favorite YouTube channels.

Bob also hosts a weekly live stream on Twitch where he works on a project and chats with people watching. It’s a fun way to interact and see what he’s working on outside of his videos. On Twitch, there is a way to send the content producer some money. It’s basically like a tip jar. On Bob’s channel, whoever puts in the most tip money during each stream gets a custom badge cut out on his laser cutter. A couple weeks ago, I was the winner. If you start watching around the 1 hour 58 minute mark, you’ll see my donation and short battle with another user who was trying to win too.

And then the video concludes with him cutting out my custom badge. It arrived a few days later with some extra swag thrown in. Thanks Bob!

For the curious, that donation only amounts to $20. I figure if I was in the Atlanta area, I’d be happy to buy him a 12 pack of beer for all the knowledge he’s given me so I just did it virtually.

Tractor Sign

For Dad’s birthday, I spent time drawing a picture of his tractor. It might take a lot of hours to get to the point where you have your file ready to cut, but after you get there, it’s just minutes to cut a new copy.

I decided to cut out a big one and put it on Elijah’s wall. The max work piece size that our laser cutter can handle is 24 x 18 so that’s about how big this one is. I sprayed on a couple coats of white paint but still let the wood grain show through. As you can see in the picture, he was VERY excited to put this on his wall.

Laser Cutting At Home

I’m very thankful that I can use a laser cutter at work, but what are the options for laser cutting at home? There are three very easy and low cost options to start with:

  1. Check with your local library. More and more libraries are supplying laser cutters and 3D printers for people to use.
  2. Order it from a website. I’ve done this for 3D prints before but the same concept applies to laser cutting. The turnaround time is slower and you pay for shipping, but it’s a lot cheaper than buying a machine!
  3. Find a local maker space. These are generally clubs that you can join and use their equipment. You pay a membership fee or you pay to rent time on a machine, but doing it this way helps you iterate faster than doing it by mail.

If you still want to buy one for home use, you should probably be getting advice from someone more knowledgeable than me, but here’s what I know. If you buy an entry level system from a company like Epilog or Universal, expect to pay upwards of $8000, and that might not include ventilation which is almost a requirement.

A company called Glowforge is making a lot of waves in the maker community because they are coming to market with a laser cutter intended for home hobby use. It has a lot of really nice features that lower the barrier to entry, and you can get their basic model with ventilation for under $4000. Reviews of pre-production units are very positive. The cost of ongoing maintenance remains to be seen.

It’s a great time to be a maker!

New Crosscut Sled

I’ve written before about making a crosscut sled for the table saw. I used the first one so much that it kind of wore out and I had ideas for improvements so I made another. They’re incredibly convenient especially for the smaller toy projects that I was doing. It’s a very safe and precise way to cut small pieces (among other things.)

My new table saw had miter slots that were a different width so I needed to build another sled. This time I incorporated some t-track and a flip stop that slides in that track. This allows me to get repeatable cuts with the stop but I can also flip it up after I set the position of the piece to avoid any binding between the blade and the stop.

The process was pretty much the same as previous builds, but because I had a much more precise saw, I decided to spend extra time squaring up the fence to get perfect 90 degree cuts.

I used my big square to get it initially set close to 90 and then did the 5 cut test to see how far off I was. Watch that link to see it in action, but basically you make a cut, rotate the piece, make a cut, rotate, etc. You do that 5 times and then you measure the width of the last slice at the top and the bottom. That helps you calculate how much out of square your sled is because it really magnifies the error. I was so far off that it was plainly visible to the naked eye. How could that be when my square said I was spot on? I futzed with it for quite a while and then got frustrated and walked away. During my break, I realized that the only explanation was that my square wasn’t square. Indeed it wasn’t! So I changed up my method of dialing it in and got it to a point where over a 40″ cut, I only deviate by 0.001″ from being perfectly square. That’s insanely perfect. In fact, it’s so good that I suspect I’m within the margin of error for my setup and my measuring tools. Plenty good enough for me.

40 Years

Yesterday was Dad and Mom’s 40th anniversary! Congratulations! They’ve been supportive as parents and been a great example of a loving marriage for us to follow.

It feels a little silly to give someone a hunk of wood as a gift after forty years of effort, but that’s what I did. I took one of the pictures from their honeymoon in Jamaica and transferred it onto a piece of pine. To do the transfer, I took a sheet of blank address labels that you run through your printer and I peeled off all the labels so I was left with the waxy surface. I printed with my inkjet printer right onto that waxy surface and then carefully pressed it onto the wood. Through trial and error I learned that you really need to give it a good rub to transfer the ink. Steve Ramsey has a good video about this process. If you’re smarter than me, you’ll remember to flip the image in your photo editing software before doing this.

I finished it off with a couple coats of spray lacquer to protect it a little and then made a support so it would stand up kind of like a photo frame.
