My CNC router easily has enough Z-travel to cut a mould that 'deep', however it would still have to be split into 4 parts since the machine isn't wide enough. That shouldn't be too big a problem though as they could be simply glued together.

The difficult bit here is probably fabricating a drawing of the part. Have you got any drawings which could be transferred into a CAD program to make a 3D model?

Just a thought, if the speaker is a true nautilus shell shape, then you don't need to draw it you can just generate it algorithmically.

Yes, that would be the obvious way to draw it if the design can be made to fit those parameters. Even if the design doesn't quite match a shell generated from ellipses, then it may still be possible to use that as a starting point for the drawing and modify it as required.

Thanks Johnathon I only sketched out what I wanted to do .It changed as I built it up .Probably frowned on by your community Ideally it would a better design if it was taller & less depth .
Thanks Peter

why would it be frowned upon?? i guess you've not read many build logs yet.. things change hourly in them threads lol.

these guys are very helpful here, i think you'll find someone to help with your idea.. my personal opinion is the way you are currently doing this will have you rocking in a corner somewhere before you complete it. and if you did you wouldnt get identical ones, at least with a cnc you could make near perfect copies

I have done a lot of sheeting today . I have gone past the the loopy stage . Actually starting to enjoying it again .I have all ways had a lot of patience at my age it helps to pass the time I will try to get it to a working stage .
If anyone could help me to make cnc snails in the future I would be very grateful slightly better shape ect
Thanks again Peter

Hello everyone I have got Pheonix working well . The fibre glasser is coming on Tuesday. I am having great difficulty finding any one to do a 2d/3d drawing they say they can but as yet to no avail . i am very pleased with the performance far exceeded my expectations . If any one can do a drawing for me i am sure we can come to an amicable arrangement
Thanks Peter

Interesting project - just had a bit of a play and here's a pic of a "nautilus" I knocked up in Rhino.

Love the drawing. G.

Hello there. Love the pics . My design is not like the er Nautilus I tried to make it like a tuba it is more elongated with a gentle even taper down to 25mm it is the first pics that I have seen in CAD. I only did sketches . If you went to hifiwigwam there is a later pic . Do you think you could do it for me in CAD to be able to get it machined out out of solid ? .It has given me a real boost to see it. My thanks again hope to hear from you soon Peter
