Chris Michielssen just sent me a test unit of his new tube cutting tool and I'm very impressed. Very simple, very easy to use, well thought out, and it produces nice clean, even, cuts.
The Cutter is best understood by looking at the pictures below.
Pic 1: Shows the entire unit from the front. Basically a sturdy L-shaped piece of plastic to position the tube. Another piece of L-channel fits inside the larger piece and is used as a block to position the end of the tube for precise, repeatable, cuts. Tube block is held in place by spring clamps. Chris includes two but I found one worked just fine by itself.
Pic 2: Closeup shows the cutting apparatus. A reinforced slot for a single edged razor blade is cut into the L-channel at a right angle to the tube. I don't know what Chris uses to cut the slot but it's extremely narrow and just the right width to firmly grip the razor blade without any hint of wobble. Keeping the blade firmly gripped is essential to making good cuts. You still need to put a little downward pressure on the blade for it to cut but you don't have to worry about the blade tracking off at an angle resulting in an uneven cut. The instructions do a good job of explaining what little you need to know to use the tool effectively.
Pic 3: Shows the parts included with the tool. I really like the ruler attached to the tool with the Zero-point where the blade will make its cut. Makes it very easy to correctly position the tube.
Pic 4: Shows back picture of the Cutter.
Pic 5: Instructions show the Cutter positioned as in Pic 1, with the suggestion of using clamps to hold it to the table. With the tool positioned like this you use your left hand to turn the tube and your right hand to apply a little pressure to the blade. But I actually found it easier to turn the tool backwards and at an angle as shown in this picture. For whatever reason I found it much easier to turn the tube with my right hand (I'm right handed) and used my left hand to put pressure on the blade. I didn't use any clamps, just my left hand to hold the tool and gently press on the blade. Worked great, and no need to clamp the tool to the table.
Overall, a very simple tool, well thought out and well made. The slot for the blade, the key element to the tool, is very precisely cut, resulting in very nice tube cuts even without a mandrel inside the tubes. Can handle every model rocketry sized tube I'm likely to cut (pictures show BT-50). Not a mass production tool, but a very good fit for the kind of stuff I do.
Really nice job, Chris. I think you're going to sell a lot of these.
