    Hi all,

    For a forthcoming project I need to cut a slot in some material to fit some edging, I have a router and will use this, I checked out a few tool sites and cant seem to find a "slot cutting bit", but only "rebaters" and such, can anyone advise of the correct name? (also any advice on doing the cuts would be appreciated)

    its a slitting or slotting cutter - have a look at trends website , by using different bearings you can vary the depth of cut , if you cant get a trend booklet email me and i'll get one sent to you

    thanks for the fast reply, I checked trends site, where the heck is the "request brochure" ?

    Im not brilliant with a router, how difficult is it to do these slots? should I get a cheapo router table? (Im going to be making one of these jukeboxes http://www.mameroom.com/vjplans_info.asp ) I dont mind spending a bit of money if it will help the finished project - it needs to look 100% if you know what I mean.

    Thanks

    And if you'd like a similar cutter, trades quality but at a MUCH better price then try Wealden Tool. A1 mail order service as well

    No connection, just a satisfied customer

    in reply to how easy it is, just practice with it a bit first, measure carfully and get it all set so you are really happy with it before you start, otherwise its fairly straight forward. You could also do the slot with a table saw if youve got one.

    I do have a table saw, but I cant see me holding a piece that large (about 3 foot x 18") without it all going sadly wrong!

    Personally I think that you'd be nuts to do it this way. It would mean passing a large unstable piece of material over an unguarded blade. One wrong wobble and you might not be counting to ten on your fingers again! :oops:

    depends if the cut is on the 3 foot or the 18 inch side. You can always set up a jig to do it

    the cut is along the long part, I think I'll stick to the routher option, thanks for the suggestion though.

    Eggplant:

    Can you tell us the thickness of that board and the dimensions of the slot you want to cut in it?

    How best to cut that slot depends on how accurate the slot width has to be and how deep the slot has to be.

    I'd say you're either looking at using a slot cutting bit or a straight bit along with an edging guide on your router.

    A slot cutting bit will be easier to handle, but you won't get the same accuracy of width of slot as you would with a straight bit.

    A straight bit will give you the width of slot you need, but balancing a big router on the edge of a board is going to be a wobbly kind of affair even with an edging guide.

    If it wuz me, I would use a straight bit in a LAMINATE TRIMMER along with an edging guide. Unless that's solid hardwood you're cutting, the laminate trimmer would have enough power, and it would be more stable sitting on the narrow edge of a board, especially with an edging guide attached.

    Pardon??? Nestor you can cut a slot of the required width by making two passes with the cutter height altered, so a 4mm slot cutter could easliy cut a 5.5mm slot, especially if the router has a micro adjuster. Running any router on a narrow edge is a sloppy and inaccurate of working.

    Hi all,

    here is a pic of the exact pieces I need to make, the material is to be 9/16ths MDF.

    I havnt started yet, I have a lot of planning and buying to do but plan to start in the next few weeks, I have been reading the plans and these slots were my biggest concern.

    Thanks

    The slot cutter is definatly the way to go, nestors way would take ages as you would need to make several passes and no doubt snap a few router bits and the table saw method would only work with an ultra thin kerf blade and would still be dangerous. I would go for Wealden cutters as Scrit says.

    The bracketed metric sizes are a bit optimistic. a 1.5mm slot cutter is a lot closer to 1/16" than 2mm. You will also have to use 15mm MDF and make allowance for this as it may affect the size of other components
