Default Taste ? (about collet)

I read about a tightening of collet in(on) a book which is recommended by Bj san like as ...
"Offset the collet wrenches hold both handles in one hand and squeese"
"You shouldn't have to be an arm-wrestling champ to tighten the collet"

And I saw a scen that Rick san tightens collet through The Woodworking Channel. This is the first time to me.
It is some kind of surprise to me. He seemed to tighten a collet quite strongly .

I wonder it might be the taste of each person how strong you tighten a collet...

Only gentle pressure should be used to tighten the collet Benny.

HI Benney

I will need to disagree with Harry on this one, it's safety thing...

I recommend tighten a collet nut all the way, that's to say put all you can in to it, the bit must stay in place and must not move or come out when the router is spining it at 24,000 rpm. ,I have in the pass got lazzy and didn't go the extra mile and they have come out, the norm. is in the wood or just come up in the slot when I'm making a pass.... that's why you should never use your hand to push stock over the bit they do come out from time to time...oil on the bit,dust on the bit,chips in the collet nut,etc. will keep the bit from staying in place..

If you watch the RWS show like I do both Bob and Rick crank the nut down, I use the off set type wrench on most of my router tables and some times I move the table just a bit when I crank them down....but this extra step will save me from making a 911 call.

Take a hard look at the wrenchs that came with your routers, some are 6" to 8" long, some are 4" to 5" long ( like on trim routers) the Mfg. knows you can just only get so much torq. from a tool that is only 6" long or shorter , the user maybe a 350lb. guy to a 80lb. person ,they know when the threads on a nut will fall and take in acount when they make the wrench for the router...(tool)

Bj. I really really have to agree to disagree with you on this point, all the demonstrators that I have watched have pressed the point not to over-tighten and don't forget Bob that I tend to specialise in DEEP routing in hardwood and have NEVER had a cutter come loose. My teaching has been that if it's a struggle to undo the collet then it has been over-tightened. Perhaps there are mechanical engineers among us who will enter this discussion.

Hi Harry

I'm been thinking of buying one or two of the new collets that lets you snap in the bit without the need to use a spaner/wrench but they are a bit high in price about 70.oo bucks or so, but they look neat and must work ok ...

That would take the guess work out of it.

==========
The ones below are for the Craftsman routers...

The one below is the same one they use in the CarveWright CNC Woodworking System

http://cgi.ebay.com/CRAFTSMAN-1-2-IN...QQcmdZViewItem

Just one more of the new type chucks for the router ▼
This would also take the guess work out of the collet being to tight or some one having a bad time removing the bit..
Plus it will add just a bit more height for the SHORT 1/4" & 1/2" bits we all use from time to time.

Just a NOTE**** the Porter Cable routers have a great collet, it has a snap on it that will free the bit,,, if you over crank it down...I have not ever had a error with a bit being stuck in the collet on the PC routers that I have and I do crank them down.

Thank you very much for your reply.
But I can not understand the meaning of "crank something down".
I wish you could tell me what is what.

Hi Benny

Crank Down =

Tighten Up
To make or become tight or tighter
To make tight
To narrow or limit

Thank you very much.
I can understand.
I should buy a good Dic.


I made a "Fake Cyclone Dust-Collector".
It works well with hose which is 5m(diameter:50mm).
But I do not check how long distance absorption can be done.

Hi Benny

I like it ,, looks like you can make some beer with it as well , but I think you need to bend the coil or add a more coils to it,,,just a bit more to get a nice beer out of it... hahahahahahah

BUT I do like it ....

By the way you don't need to buy a god Dic. you have one on your computer

Well done Benny, we have a saying, "necessity is the mother of invention" and you have just proved it.
