consider safety for your health and the people around you

General safety suggestions:

It is advisable to always have the following items nearby and in a good condition

  • Eye protection clean and scratch free
  • Hearing protection quality earmuffs
  • Dust masks discard old and dirty masks
  • Gloves for easy handling of material and hand protection
Wear Gloves
Eye Protection
Hearing Protection
Dust Mask

To use router bits safely (and to get the best results from your router), the router bits need to be installed properly into the router's collet. Improper installation of your bits can cause excessive chatter and could increase the likelihood that the bits will break when in use. 

Clean and sharp

First of all, before beginning any routing operation, check your bits to make sure that they are clean, relatively free of pitch, and most of all, sharp. If the bit is dull, chipped, is excessively burned or has any other defect, it should be sharpened or replaced before use. 

Correct collet and collet nut fit

Most router collets have a recess (groove) that needs to click into a circlip that resides inside the collet nut. Failing to ensure that the collet 'clicked' into the collet nut will cause you to struggle to remove the router bit after tightening. This could cause the collet to break or be removed by a technical repair centre.

 

Correct fit inside the collet

When installing the bit into the collet, do not tighten the collet with the bit 'seated.' Instead, insert the bit until the shank (bit shaft) reaches the bottom of the collet, then ease it out about 2 mm before tightening the collet.

When the bit is tightened, there should be no less than  2/3 's of the length of the shank in the collet. If your bit has a shank that is too short, then the bit should be replaced. 

 

Safety gear

There are a few other safety measures to keep in mind whenever you use your router. First of all, remember to always wear appropriate safety gear as indicated above.

Correct speed setting

Second, be sure to set your router to the proper speed for your router bit. Setting your router to an incorrect speed will not only affect the router's performance, but also can cause the bit to break much more easily and even cause bodily harm. The speed at which a router bit turns can be important. The typical router runs at about 22,000 rpm, which is fine for most bits. But as the diameter of the bit increases, you ll want to slow things down.

Also, before beginning any routing operation, be certain that you give the router's motor time to come up to full speed for the chosen setting. Beginning to cut before the bit is at full speed can give less than desired results. 

Observe the following at all times

  • Wear a protective face shield or Safety Glasses to prevent eye and face injury.
  • Wear ear plugs or ear muffs to protect your hearing.
  • Use a respirator or dust mask to give protection from dust particles. Wood dust may remain in the air for hours after using power tools.
  • Always read and follow router operator's manual instructions.
  • Make sure that router rpm's and the bit selected match.
  • Dress properly. Wear short sleeves, no loose fitting clothes, proper footwear and no jewellery. Tie back long hair.
  • Always be sure the router is unplugged before replacing bits and that the switch is off before connecting the router.
  • Be sure the router bit has completing stopped spinning before sitting the router down.
  • Be sure bits, clamps and attachments are secure before starting up.
  • Keep children, pets and visitors at a safe distance.
  • Be especially cautious when working small pieces.
  • Keep hands and fingers away from revolving bits and cutters.
  • Do not operate routers in moist or wet areas.
  • Always grip tool tightly and be prepared at start-up to resist the motor torque.
  • When using a router table, make sure on/off switch is easily accessible.
  • Learn the sound of your router and shut it off at any unfamiliar sounds or irregularities.
    Never start the router with the bit in contact with the material.
  • Always feed in the proper direction, against the direction of bit rotation.
  • Maintain equipment. Replace worn parts, discard worn-out bits and check router periodically. Clean parts with appropriate solvents.
  • Don't operate a tool if you are tired or under the influence of medication, drugs, alcohol or while smoking.
  • Check wood for nails, screws or loose knots before routing.
  • Keep your mind on your work, avoid distractions, work at a comfortable pace and stop before you get tired.

Do a dry run

  • Place the router on the final work surface and test you cut by moving the router over the whole are to cut with THE ROUTER SWITCHED OFF
  • You do not want to waste an expensive piece of wood
  • You do not want to start all over
  • Never met anyone with spare fingers - SAFETY

Using a Router in a Router Table

Router Table Safety

Although most router bits are small, they can be potentially dangerous and should deserve your attention and respect.

1 Use push sticks or a push block to position your hands a safe distance from the router bit.

2 Use large-diameter bits only in a router table. Using bits over 25mm Ø (diameter) in a handheld router can possibly cause you to lose control of the tool and harm yourself or bystanders.

3 Always wear a dust mask as well as eye and hearing protection.

4 Take light cuts. Heavy cuts invite kickback. If necessary, move the fence closer to the bit or switch to a larger guide bearing/bush.

5 Use a featherboard (anti-kickback device) to support the workpiece against the router table and/or fence.

6 Never climb-cut. Always feed the stock from right to left. Against the rotation of the router bit. (see illustration)

7 Avoid routing small stock. Instead, rout a larger piece and cut it to size afterwards. If you absolutely have to profile a small piece, build an suitable jig or secure the workpiece.

8 Always use a guard. If the fence didn t come with a guard, make your own.

9 Never start the router with the bit in contact with the material.

10 Don t force the router bit or overload the router. Excessive heat is an enemy.

11 Secure/fasten the router in the base before starting/switch on the router.

12 Don t bottom out the bit in the collet or partially insert the bit. Instead, completely insert the bit, and then back off approximately 2 mm. At least 2/3 's of the router bit shank should be inside the collet.

13 Be sober and not under the influence of medicine that causes a lack of concentration

14 Tidy up your workshop to ensure the ability to move freely with enough room around the router table

Final Fantasy Ultimania Archive Review
Format: Hardcover
This is a quick review of the book from darkhorses latest production the Final Fantasy Ultimania Archive. This book coves covers final fantasy 1-6 in various sections. The various sections for all the final fantasy games are listed as follows : 1. Art 2. Final Fantasy (Insert number here) Story 3. Characters 4. World 5. Monsters 6. Extra Content - goes into different sub catagories and varies from final fantasy to final fantasy. 7. Last section is - Final Fantasy (Insert number here) Memories. I have to say I really like this book a lot, but then again It's a dark horse bool publication of course it's going to be good. The pages are THICKKK. When I thought they were glued together or something by accident but nope, these pages are just really that thick. The hardcover is nice, although best to keep it clean since it's mostly all white. My favorite section is probably the character section. Not only does it list which character is conected to who in some way as well as the villians but also it shows Yoshitaka Amano complicated and beautiful artwork bellow each of the characters pixilated forms. It really gives you a perspective in how Amanos art work was translated into these sprites. Even though the section on art is nothing special seeing as I own "The Sky The Art Of Final Fantasy Slipcase Edition" which I recommend btw, It is still no less nice to see his work here too. I do think we get to see more of his monster desgins here though, but also the art covers for each variation of the game like from the Famicon to Android to PlayStation. It also shows the different logos that were in other platforms/handhelds or media devices. Really cool stuff here. The story section is OK, doesn't really go indepth about it though. Nice but overall just an OK section. The world section is pretty cool, showing the entire map of each game. The final fantasy 1 map is super basic, with some green here, dots of green for bushes, some yellow there, etc. Overall a neat little section. The monster section does the same thing with the characters section in the sense that it shows you Yoshitaka Amano fantasic drawings along side the pixel forms they take in the games. Incredibly fascinating if I do say so myself. The extra content section is were you see the technical side of what went to making into these games like the sprite data, the map, color list and so on and so forth. This section varies from final fantasy to final fantasy but it gets really technical about it, really cool. The final section the memories section is just that, memories of the game with random images and quotes of the game. Final Verdict - 10 out of 10 I did check in the back of the book for a final section called creators voices which are short interviews with the grand masters of the final fantasy series itself and how they feel about their work. Really nice. Overall this is a well done book by dark horse books, yet another fantastic release guys. I highly recommend buying this book regardless if your a collector or not. My recommendations? Pre-order Volume 2 of The Final Fantasy Ultimania Archive, it comes out in december but still. As well as Pre-Order any of the upcomimg dark horse books, they are all really good regardless if you played the games or not.

A Must-Have for any Final Fantasy Fan
Format: Hardcover
GeminiGeek's Honest Review! If I had to review this Ultimania Volume 1 with a single word, I'd simply say: "FANTASTIC!". This first volume of the Final Fantasy Ultimania books covers the first six Final Fantasy games, and has an enormous amount of details and content. Each game has it own individual section, complete with images of each character's classic sprites, and even their official Yoshitaka Amano art work as well. Aside from being visually appealing, the book is overflowing with unique story details, character bios, and even an encyclopedia of items and monsters! This volume of the Ultimania series is thick, it is huge, but not to the point of being a pain to carry around or hold. If you enjoy any of the six Final Fantasy games that this volume covers, you'll find something to love in this book, there is just so much information and artwork contained within this tome. This is a must-have for anyone who enjoys the Final Fantasy series, I can't recommend it enough. As a long-time Final Fantasy fan myself, I love this book, and I can't wait for Volume 2 to come out this fall.
