Have you been drilling masonry with it?

If so flush it with some paraffin to get the grit out then when dried off use light 3 in 1 type oil.

Also check if the chuck is held captive with a Left hand thread screw in it's centre (between the jaws) this sometimes comes loose and jambs the jaws.

EDIT: Sorry Generic "Jacobs Chuck" registers as standard three jaw drill type chuck with me, not one specific to Routers.

This actually a chuck for a router not a drill and only used on a woodrat.
i can lock the chuck with nothing in it but as soon as you place a bit in it weather half inch or quarter it is to tight

I assume the chuck is rated for router speeds as drills tend to turn a lot slower. Is it a keyed or keyless chuck?. A spray of a dry lubricant such as GT 85 may be worth a try. If it has been overtightened then there may be internal damage.

I think it is an american thing , i bought of ebay sometime ago . It is like a big fancy collet with a collar that you lift to lock the bit no tools required and fast to change ( well it used to be ). i've had a look round for a picture
and found this although for a porter cable

John,
That chuck was discontinued as several problems emerged in use. Failure to lock properly was one of those problems.

I recommend you do not use it and instead use a PC ELiminator chuck or an Xtreme Xtension (plenty of mention of both on this forum if you use the search facility).

 

[John p]

i've had no problems with this till now unlike the Xtreme Xtension which i also have . The Xtreme Xtension suffers from lots of vibration and lots of messing around with long setup times

John,
I get a lot less vibration from the PC Eliminator compared to my XX. It has the same quick change ability for bits as the XX but he chuck is a totall different design.

I had a Jacobs PowerCollet on my DW625 until it started ejecting bits. I decided I didn't want a 1/4" spiral upcut bit stuck in my leg so I opted to remove the PowerCollet. I had to destroy it to get it loose from the router.

I much prefer the Eliminator Chuck. It hasn't vomitted a router bit yet.

Reputedly, they were withdrawn from the market for a reason.

Thank you all for the advice , i will have a look round for the Elliminator
