Re my question

Hello every one . As stated I do not know anything about cnc . So here goes please bear with me . If you go on to pink fish hifi diy you will see my post . It was recommended that I contact you for an SOS . My post is Peters snail speaker pheonix . I have had an illness which meant I have been indoors most off the winter . I am still very active & still like to get items working well . I can make a mold by hand but it is a big undertaking for me in foam . If you you knew how many hours I have taken to get where I am you would all be millionares
Please view
Many thanks

This is presumably what you're talking about:

My snail speaker I call it Pheonix - pink fish media

If you put the link in your post it would save readers the faff of googling it just to find out if they want to help you. Just copy it from the address bar in your web browser and paste onto a new line in your forum posting.

Some dimensions would help too so people could know whether it would fit on their machines. Looks larger than most DIY CNC machines will be able to tackle in one piece.

Thanks for that .I am just going out will do that when I get to the other destination . I am not too good on computers
Thanks

Hi Peter, wellcome to the forum. Your snail spreaker looks very interesting (different). As you have made a substancial wire frame, would it be possible to skin it as in your model aircraft days and then get a fibreglass mould on that? Anyway, good luck. G

If you can amke a mould that is split into a front half/back half shinobiwan might be able do it on his machine. You can see a video of his loudspeaker work in the thread here:

Hello Geoffrey It is being skinned now .It is taking a long time it is not wire but ply wood. The dimensions are 1200 mm high the front 404 mm,the width is 902 mm so it is fairly large other wise I have to set too to make another
Thanks Peter

Thanks for that.Iwas going to make a plug out of expanded foam hoping somebody could cnc in two halves I think will be difficult by habnd

Thanks Peter

i believe this is the sort of effort you are trying to achieve. and i think splitting it in 2 halves is the only way to do it.

this picture shows a mould that they are applying fibreglass to a imagine, where as if you only wanted 2 pieces you could get someone to cut this straight from a cnc provided that person had a big enough travel in height.

Those new ones work fine and are direct links.

Old one still doesn't show, you sure it's just me?

hows that?? i redone it

Thanks Wilfy . I have tried to make it look like tuba . With a single driver installed . Do you think it could be cnc laser cut . As said cnc is rather beyond me we only had log tables in my day
thanks Peter

Peter, I don't think laser would suit this job. Lasers are good for engraving and profile cutting. I also doubt if most people would be able to cnc router cut it due to its height. One way to do it would be to build it up in sections, cutting the Whole shape (like rings) in layers glued together, sanded to lose the steps and then cut in half - tedious, but do-able. G.

Thanks Geoffrey . It is a difficult one . it has 6 meters of piping that is why it has been so difficult to . A friend comes in every week to see how I am getting on . He said I don't think there is anybody in the world mad enough to attempt building it . I will try & figure a way forward .
Thanks Peter .

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.

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

Easy there big fella :calm: one step at a time... bashing out the nautilus "freeform" model is one thing - working to a brief is another. Link to what you have and I'll take a look see.

nearly forgot...

I have at last found someone to draw 2d/3d cad for me it is being drawn now . It is a relief for me . The prototype has been glassed needs the final skim & polish for the mould to made in the next week . I am so pleased over the outcome . The performance has exceeded my expectations by some margin . I will need some one to cnc router out of solid for me if anyone can help I would be most grateful . It has taken me 6 months well over 700 hours . I must be mad !! don't answer it I already know . It has taken its toll on me medically . I saw my hospital specialist he said have you had any stress lately oh no no no I said The designer said how on earth did you make it & how long . I said British grit & determination .I have tried 5 15" drivers bored 3 out to take a tweeter . would you believe that the cheapest sounds the best at the moment . Seriousley thinking of making my own up to my specs . Here i go again .

Thanks everybody for your help be in touch soon Peter

Hello everyone I am back . Had my long term illness come back with a vengance been in hospital for a while . I must come clean about it I have had ulcerative colitis for most of my life it jumps up & bites you with no warning The begining of the year had a massive reaction to azathioprine medication . rushed into hospital recently could not control my condition with cortizone. My only chance was Remicade .It is not recommended for over 65 s it was administered late at night it worked within a few hours so grateful

It has given me a life which I havent experianced before . Just got to get my strength back .My greatest thanks to Winchester hospital
I have the 2d drawing done to be able to cnc in 2 or 4 parts is there anyone who could undertake the machining for me please .

Many thanks Peter

Hi Old timer. . . . Sorry to hear about your poor health but pleased your feeling better.

Post the drawings and I'll take a look or if you prefer not to post then you can email me. I'll PM you address.

Cheers
Dean

Thanks Dean will get them tomorrow do have them in pdf file
