Default Switch collet from 1/4 to 1/2 inch?

Hello friends, this is my first post. I am building a router table with an 8 x 11 x 1/2 inch thick aluminum sheet for the insert. Problem is, my sears craftsman router won't extend its collet far enough for the bit to protrude enough through the 1/2 inch thick sheet. If it had a 1/2 inch collet, I'd just get an extension, but the quarter inch collet (from what I've read) will make any extension too frail. So, my question is: can I replace the 1/4 inch collet with an aftermarket 1/2 inch piece? If so, would it be a simple drop in replacement, or would it require more extensive modification? Finally; if this is not possible, do I have any other recourse (other than buying a new router)? Thanks all,
David

Buying a new router; yes.

Methinks you be stuck...not aware of extension for 1/4" shank and have not seen a 1/4 to 1/2 shaft adapter...

Besides the 1/2" board you are using, did you install any additional spacers that you could remove...? Maybe you have the router base plate installed also...? And are there specific bits for which you cannot the proper height...?

A 1/2" doesn't sound like it should prevent proper bit height...some of the table plates sold are 3/8"...

And welcome to the Forum...

The collet being part of the shaft makes it hard to enlarge a 1/4" to a 1/2" dia. shank size. I have never seen it done. The minute I read "1/2" inch thick plate the first thing that came to mind was the depth of cut. I think that either a thinner plate or a new router as Dan suggested.

OK; that was just mean. Here's the reasoning;
1) what's the HP on your Craftsman? It may be really underpowered to swing a hefty 1/2" shank bit.
2) 1/2 Aluminum sheet is massive; why so heavy?
3) folks frequently come to the Forum looking for Craftsman parts. Not a lot of good news in that dept.
4) further to #1, if you've installed a 1/2" collet you will be tempted to use any and all 1/2" bits, even if they're totally inappropriate for your router.
Other than the 1/4" trim routers, most of the modern 1/2" machines are at least 2HP or better. Even then, there are safety and practicality considerations over how big a bit, and how deep a cut one can use.

If it has ONLY a 1/4 inch collet, time to buy a new router. My fave is the Bosch 1617, which has both a half and quarter inch collet. In other words, you can drop down a size, but not step up to larger. Beside that, the Bosch has the ability to mount under the table and be adjusted through the top. Sorry for the bad news. Don't drill your plate because not all bolt patterns are the same.

One more thing, when mounting your present router, did you remove the plastic base plate before mounting it? That will give you a quarter inch or so more. Also what size is your opening in the plate. It should be large enough for your largest bit. You use an insert to fit the opening to the bit, which is pretty tricky to make work yourself. That's why most of us just bite the bullet and buy a pre-fitted plate. The pix is of the Woodpecker plate which has a twist lock insert. Kreg also makes plates with twist lock inserts (Blue plate pix), much cheaper that the woodpecker BTW.

David Hello and welcome to the router forum

My suggestion if you really want to learn to enjoy your woodworking buy yourself at least a 2 1/2 horse with 1/4 and 1/2 collets plunge Router you should never need anything else,
No matter what craftsman router you .buy within a year maybe two you won’t be able to find the parts for it
There are a ton of used-Router’s for sale a lot have never been used
I believe in the long run you’ll be happier

Looking forward to your participation.
Filling out your profile to include (first name,tools and short bio is strictly (optional )but does help members to better relate to each other.
Thank You John

Many routers have 1/2" collets as well as 1/4". Don't know if your CMan router does or not. That's the first thing to consider. As Dan pointed out, though, that may be a quixotic quest.

1/2" shank won't really buy you much more height (depth?). As others have pointed out, something doesn't seem quite right. You should have a fair amount of depth for your router. Are you sure you have it mounted correctly?

Finally, I know people are in love with the musclechuck but I think extensions, in general, are a bad idea. I think the MC is safe but would be very leery of anything else. Especially on a 1/4" shank. A broken bit being flung at 24k RPM isn't fun to dodge - don't ask me how I know this. If nothing else you're gonna get more runout so things like box joints and dovetails will be a problem. Best to just bite the bullet and get a newer router with 1/2" and 1/4" collets. Having both is a very useful thing, btw.

If you are really Set on using that router you might contact Muscle chuck like Phil suggested:

https://www.amazon.com/MuscleChuck-R...SIN=B01NAGOCXA

and see if they make a Musclechuck for your router, it will give you a 1/2" more height. But that will be a $100. you could put in another larger router in the near future.
Just a suggestion.

That is an excellent summation on anyone's situation going forward, Phil - an a true acknowledgment of the need for a proper router plate/lift combination for all matters considered. I've been down this road and don't want to go back!
