    I have just bought a dovetail jig,lumberjack dtj300 and i need a 1/2" bit/1/4"shank with a bearing so it dosen't foul the fingers.
    I have an erbauer 1/2" router with a 30mm ID /83MM OD.guide bush
    I have a 1/2" doveatail bit which has a 1/4"shank but no bearing,so no good,is it possible to buy a cutter and remove the bearing,as toolstation have got bits with bearings from as little as £3.24.
    If its not possible i will have to buy one which will cost £12.20.
    Or can you recommend anywhere that sells a guide bush that is 12.7mm ID/83mm OD.
    Ive attached an image of my base.

    I'd be looking to see if Erbauer sell a 12.7mm guide bush for your router.
    Why is the 30mm guide bush in your pic upside down ? It also looks very very narrow to be 30mm.

    Its not upside down,that's the locking nut in the center that's probably throwing you off,pics from another angle with actual sizes.

    I would fit a sub base, then you can use 60mm diameter bushes as used by Dewalt,Trend & a few others, makes life a lot easier.

    Trouble is, there is no standard size for router bushes, Bosch have their own system, at least Dewalt & Trend have got it right in my opinion.

    Here is my diameter in pic.
    Just a couple of questions regarding the trend unibase.
    Is the center of it to accept guide bushes 30mm OD?
    Do trend do a 12.7mm guide bush?
    cheers.

    I will look at that cutter,i just thought that as it's only 11.1125mm and not 12.7mm that i would need this one from trend?

    o_Oo_Oo_Oo_Oo_O
    So i either,
    buy the trend cutter that is 12.7mm for my dovetail jig £12.20
    Or buy the 7/16" cutter £10.99
    7/16" template? £16.45
    Im going to pop to toolstation now and look at this cutter to see if i can remove the bearing as that would be even cheaper :)

    Watch this video, explains better than I can.:)

    A lot of peeps don't realise you can make sliding dovetails with the jig.



    Using a bearing cutter, you don't need to use the guide bush,as bearing is the guide,if you use cutter with no bearing then you need the 11.1mm bush.:confused:

    Cheers KIAB,i'm going to order the 7/16" cutter now.
    And thanks for the video link also.
    I was only intending to go for the cheaper option and get a bearing cutter.

    Doesn't your router have a 1/4" collect you can use.

    Yes ive got a 1/4" collet so just get the 7/16" cutter?
    One last question
    How do you work out the depth?
    Mine says,
    DIA of router base 2
    + 2x thickness of workpiece
    - cutter DIA 2
    is yours the same calculation?
