    Customer photo review of Letter Puzzle Alphabet Digital File

    It took me about three tries to get it right, user error. Once I tried things out it worked out very well.

    Customer photo review of Jul 2025 - American Flag Eagle Kit - HDPE

    I like this kit, the included vectric file worked just fine for me. I had one small issue (on one side of the big black HDPE the black cut away to show the white - on the other side it didn't). I didn't panic and reset the zero a bit lower and cut again and all was well. I'm sure some of Ryan's videos where he demonstrates he's not perfect but continues on after a glitch helped me. Overall, this was an easier project than I anticipated and HDPE is fun to work with.

    Customer photo review of Deer Inlay Digital File

    Decided to go with a 30 deg carving bit for more detail and use a black epoxy inlay. Came out really nice. Thanks to CIC for a great project. Keep them coming!

    I submitted a prior review for the 250th file and clock kit. I just have to brag a little bit because I submitted the clock to the Twin Falls County Fair and won First Place and Best of Class for Fair Theme Woodworking! Thank you CIC Workshop for helping develop the skills I needed (along with the files, materials, bits, and kits) to achieve this!

    This bit is a beast. I’ve used other flattening bits before, but this thing is phenomenal. I’ve flattened about 15 boards in the last couple of days.

    Customer photo review of BamX - Bourbon

    I love this BamX. I only wish they offered more choices and made the outside layers thicker. I have so many more ideas but I am limited because of the thickness of the outer layers. Even a reverse of the colors (light, dark, light).

    Customer photo review of 3/4'' X 5/8" Bowl & Tray - 1/4" Shank - BT275

    I loaned a new Shapeoko 5.1 Pro CNC router to TekVenture Makerspace last winter, but only recently had time to start using it for some of my projects. One of the first has been thank you plaques for donors to Scouting America projects. I found that the BT275 - 3/4'' X 5/8" Bowl & Tray bit with - 1/4" Shank did a great job of making smooth, nicely shaped backgrounds for the artwork. The bit cuts very fast and very smooth. I usually do a light 320 grit sanding between bit changes to remove the faint path marks. But that is minimal. This bit saves a lot of time and make beautiful product.

    Customer photo review of 1/8" x 1/2" O'Flute - 1/4" Shank - OF215

    It cuts plastic like a hot knife through butter. I had to order one online in a pinch that was a dull dog and had to abandon the project when the CIC beast showed up! The next day.Note to future Greg when ordering bits order 2… “ 1 is none, 2 is 1 theory”

    Customer photo review of TrueFlat - 1.25" Surfacing Bit - TF2125

    Worked like a dream. Very true to flat and having the ability to change cutters versus purchasing a whole new bit every time allows for years of use from this one purchase. Well worth the money!

    Customer photo review of TrueFlat - 1.25" Surfacing Bit - TF2125

    I bought this, for one I needed a new flattening bit for my surface board and second it was cheaper than a drum sander. I need to sell a few more boards before getting that sander. This bit did an awesome job. I used it to flatten my cutting board and it left a great finish. I think I could have went straight to 120grit and skip 80. I didn’t, but sanding with the 80 was much faster than before. If you need a flattening bit this is a great bit. I’m using it in a makita router for a spindle.

    Customer photo review of 30 Deg V-Groove - 3-Flute - 1/4 Shank - VSC30

    Thanks to Ryan's YouTube video on doing V Carve Inlays, I have done over 40 inlay projects using your 30 degree "V" carving bits. This project below is a Floating Plaque that I just gifted to a local center that offers free services to cancer patients. It is held up by concealed magnets and anchored down at the bottom with fishing line. As they are having a fund raising event I have also donated the Marble Maze game and the spalted sycamore end grain cutting board that I purchased from CIC The Kin logo and the Welcome To Kin are V Carved Inlays and the Heart & Hands are regular Inlays. The white text is done with white wood filler. Thanks again to Ryan for his great V Bits and for sharing a lot of CNC woodworking tips to us hobbyist. Much Appreciated. Mark Barr
