Today we’re watching slow motion router kickbacks at 19,000 FPS and talking about how to avoid it. I go over the three main causes and different techniques for routing safely. I also say the word “massive” as many times as humanly possible. Thank you to Bits and Bits for Sponsoring this video. There is a discount code in the pinned comment and description. I really can’t wait to see what you create! Let me know what you’d like to see next. Thanks for watching! Please like, comment and subscribe. Cheers!

I'm used to larger, corded routers kzfaq.infoUgkxfQ5_mgwq6PcudJvAH25t-I4D-3cTPz4z so this was a different experience for me. Basically, this is an incredibly sweet machine, fits well in the hand, etc. It has slightly less power than I'm used to, but that's understandable. Maneuvering freehand takes some practice. These days, it's especially nice to be able to avoid power cords. This is above the level of a hobbyist but below a pro level.

@thomaskorn2127 4 жыл бұрын

About a year or so ago I was working on a project where it was an absolute pain to get close to the template and I just wanted to get the project over with. I tried taking too much material off at the end grain and the bit had caught the wood and pulled my hand into the bit. It hurt A LOT, but fortunately for me the wound wasn’t very big, just painful. It had fully healed after maybe about 1 week or a little longer. It was definitely a wake up call for me because I know it could have been MUCH worse. Everyone please be safe and take your time before you make a cut you’re uncomfortable with. I 100% agree with getting spiral bits over straight bits. I understand they cost more but they are well worth the money and definitely safer. I’m sure if I had just paid the little extra, I wouldn’t have hurt myself.

@dondale68 Жыл бұрын

Had almost the exact same accident. Trying to remove too much material and the kickback threw my hand into the router bit,,, Lost half my left index finger!! I tell everyone I meet now ''You don't take shortcuts!!''

@donaldcharlong9586 4 ай бұрын

The generous explanation here is that you are misinformed. The fact is, every kick back that you showed was caused by "climb cutting". Even though you were cutting in a conventional direction, you were not removing all of the material up to the template. This left material behind the cut which allowed a climb cut situation. If you are going to talk about safety then you have a responsibility to be correct. Every other explanation that you gave was secondary or irrelevant.

The larger bit is also better due to angular velocity. The larger the bit, the faster the outer cutting surface is traveling at the same given RPM. Increases velocity combined with increased mass means the Wood has less of a chance to deflect or displace the bit. I get the bat and truck reference, but needed a few finer details. Great video!

Great demo, Jonathan~! Yes, kickback on any tool is frightening in the moment that it occurs, but a router (for me) adds an extra degree of "scari-fication" (lol) because you're usually closer to that spinning bit than with blades on other tools. I've already been using Whiteside bits for a while, but I definitely agree that the Astra-coated bits are great~! Thanks~!!

I have routed for well over 20 years, and only use a straight bit. I rout end grain with no problems, because I make very shallow cuts, and do so very slowly. There was no mention of routing a small piece, which is just what it looked like was being done at the start of the video. My templates, as most people call them, are all two layers of 1/2" plywood glued together, this give a lot more grip when routing - but with something around 3" or so, I either stop routing entirely, or make a jig to hold the piece. Small pieces like that are hard to hold, and will get tossed by the bit pretty easily. It also helps to be slightly afraid of your power tool, it makes you work a lot more carefully.

@billybrown6330 6 ай бұрын

The failure point causing the kick-back in your video samples is due to the lack of holding the workpiece. I would recommend using a Router Shield to get a better attachment point of the template. The template will need to be attached to the top side of the workpiece and the template is attached to the bottom side of the router shield. You can configure a template to the bottom side of the work piece and attach spacer blocks to the top side of the workpiece which attach to the Router Shield. Please note the bit rotation. The majority of router bits available are for clockwise rotation. When the router is inverted in a router table, the bit rotation will be counterclockwise. This means that the workpiece must be fed to the left side of the router bit. Pre-cutting the workpiece is very beneficial. However, proper attachment of the template is important to ensure a proper copy of the template. With that said, properly holding and feeding of the workpiece into the bit is also essential. A Router Shield will completely change how you use a router table. You can purchase a Router Shield from mobile solutions.

@petergamache5368 4 жыл бұрын

Have you checked your router for runout? At first I thought the straight bit was bent (note the uneven pattern of pitch on the blades) but by the end of the video, I'm not so sure. The ultimate trim bit also seemed to be wobbling in the slow motion shots ... leading me to think you may have a bigger problem. It could be dirt in your collet, or it could be mechanical wear/damage. To test, get a length of 1/2" reamer blank = part 3023A245 from McMaster-Carr. Chuck up the blank and put a dial gauge on it as you turn the router by hand. You'll be able to test different variables: replacement collet, new bearings, etc. until you get your router back in shape.

An interesting take on it. I’d have liked to see a bit more on the use of fences to at least partly address the problem. Spiral bits look to be a big help, even if they’re very expensive. I was looking at both upward and downward cutting bits but have no idea when you would use one over the other.

@simonmurray2002 4 жыл бұрын

Thats a cool video and it explains a lot for me. There is more to consider with bit diameter, say 1/2 inch vs 3/4 assuming you kept the rpms constant at an arbitrary 20000rpm then you will have a tip speed (angular velocity) of 12.5m/s for the 1/2 but just under 19m/s on the 3/4 this means less time for each cut and less time between cuts. The addition mass of the bit will help sustain the speed if it hits a hard bit and then as you said the extra rigidity really helps. Can't wait for the next one, nothing like seeing the science behind what we do
