    Hello chippies
    I am doing a job for someone and i need to joint two sheets of MDF together i was thinking of a maitre with a grove cut down and a grove on the other board and a length of timber say 10mm wide to hold the miter in place as i don't want to screw it is there another way to join boards

    the quickest most effective method is a biscuit jointer

    Hi Blokes. I ain't a chippie,so shoot me down in flames if you want, but as I understand the problem, Tim wants to join 2 MDF boards at 90 degrees & is asking about rebating each board & then beefing up the joint with 10mm square strip.....sounds OK to me...

    Regards, Malkie

    Ok Tim
    Really it's down to what your using and what tools you have and the designs are wide and varied. I'm sure some one here can pass you a patented plan and you could take it from there. To join say 6 or 8 mm pegboard mdf would not suffice . If you can router you could house the front in to a frame and use sold ends and top with a shaped plinth. To butt two 10mm boards without fixings is not on. Go look at a ready made job and start again. Good luck . I'm sure a plan will be with you from here soon. Cheers !

    ....Tim, I think that you would be better off with a 20 or 25 mm strip if you want to glue &/or pin it..Malkie...

    butt joints in MDF, biscuits

    corner joints in MDF, biscuits

    tee joints in MDF, biscuits


    a cant make it any plainer, USE BISCUITS and stop listening to the drivelling numbskulls

    Hi DD. Maybe Tim hasn't got a biscuit jointer...Hardly worth buying for one job. If he rebates the edges, he can use a router or even a circular saw at a push. I'm sure that your's is the correct way, but sometimes us amatuers have to compromise (bodge ?)....

    Why not just screw it together and fill the screw holes.What is all this rubbish about biscuits.The biscuits wont hold the joint together until the glue is set
    If you wanted to be fussy the corners should be mitred glued and pinned

    Personally, I would butt it, glue it, and fix it inside with stretcher plates(90°)for the corners, IF the design allowed for the brackets to be hidden.



    Mr. HandyAndy - really

    dont some of you ever listen

    biscuits are for lining up joints

    never mitre structural joints (in any medium, timber, MDF, MFC) they have no strength and you cant reliably cut a long mitre

    dont pin MDF joints it splits the MDF
    screws in MDF always predrill use 3.5mm dia screws (not 4.0)

    gluing joints is a given, didnt think it had to be said
