    Thank you everyone for your input.
    For starters, a vacuum table or clamping isn’t required. I have designed the cut-outs to have a top and bottom tab, so that the disk remain attached to the board when routing.
    Regarding the cost, I am a builder with 10’s of thousands of pounds of tool; can you imagine telling a client that there is a rental change for the tools as well as labour, materials etc?
    Horse for courses….
    JazzCNC, I am not sure why you would be laminating large sheets together? You may have noticed the note that it’s 18+22mm ply. This is because I’m in France and 40mm Ply doesn’t exist here, but it does in the UK.
    Also have you ever tried planning Plyboard across the grain? You can’t, it will rip the layers apart.
    I am going to take Jonathans advise and stick this post on RFQ.

    So did you have those tools given free.? . . . No they get factored into the job or they come from your profit. Either way the client pays for them whether they know it or not that's business.!!

    Yes I did see that from drawing and presumed the quote the would have been based on this.?

    Yes I used to make Bespoke furniture so I have and it's very easy to plane if you have the blades ground correctly and nice sharp plus don't be greedy on depth of cut.!!
    Thou depending on the finish you require I'd be more inclined to make a Jig for bandsaw has it will be quicker and more controllable.

    You could also make a jig and use a router with large bit.?

    EDIT: Actually this could still apply with CNC and would actually be quicker. Cut them out, make a Jig at required taper to hold 5 or so and then use wide tooling bit using a normal surfacing toolpath. Will be much faster than 3D toolpaths.

    Will be lengthy job has it's lots of 3D toolpaths with small step over but still should come in cheaper if done in a shed.!

    Hi JazzCNC,

    This isn't a project I fancy doing by hand. I have 102 disks to cut plus another 102 as I want to make a pair. This would be 408 circle to cut plus making a jig for a router.

    The main reason for not going down that hand made route is the angles of the tops of the cylinders. A fair few are at different angles. This is to time-consuming as I work 60hour weeks.

    I have started a thread on - http://www.mycncuk.com/forums/projec...html#post49692

    I'd love a 5-axis machine for £15k!

    It is one of those parts that although you think would be simple to make, is actually quite difficult.
    I'd go for Jazzs suggestion of get them done on a 3axis, but get the tapers stepped/waterlined, then finish on a sander. A jig on a decent (i.e. a floor standing one, not a stupid handheld thing!) belt or disc sander will remove the remaining material pretty quickly. Might not be the quickest or cleanest method, but it'll do the job.
