could anyone recommend me someone that does wood cnc need 4 small oak pieces routed had no luck when contacting places local to me this is what am trying to do a clone speaker https://www.printables.com/model/628716-bneck-speaker
I could produce ur speakercases. But iam sitting in Germany. May be the shippingcosts r high. But u should know that Full oak cases r expensive. If u like contact me to info@liquidextasy.de Some of my builds:
thanks for the reply, but with the stupidity that is brexit i cant take you up on your offer, shipping fees and import duty are a major ball ache. your builds are awesome tho
Have you tried @ Maki role? I'd offer, but the shipping would make our German friend faint, and the wood available locally is trash. You are probably having trouble finding a fabricator because oak splinters at the slightest provocation, and it gums up mills.
who is maki? i have a fair bit of oak ,and walnut as well but am keeping the wall nut for a center speaker i am planning further down the road was not aware oak was so bad on the mill bits
@Yaka . I can help mate. Nothing wrong with oak if using carbide bits. How big are the pieces you need cut?
Size is fine. May you please send me a pm with a drawing or 3d parts so I can take a look. I'm assuming it's glued together in layers, so you'd need 3 or 4 layers? I only have one concern. That hole on the front (narrow side). That would have to be cut afterwards and the 193mm is too tall for the cnc router, so would have to be done with a router and template. Not difficult, just something to bear in mind.
yep i have about 12 or so pieces of oak around 30cm length and width and 2.7cm deep. i uploaded a step file on my printables page https://www.printables.com/model/628716-bneck-speaker
Thanks for that. Do you have any woodworking skills? Being that the speaker was designed for 3D printing, there are a few things we need to address if doing it in oak. 1. Wood moves. No way to stop it. Unseasoned wood moves a lot. Oak moves a LOT. Cutting away large areas from a chunk of wood tends to release tension in the wood, making it bow or cup. Oak is very open grained so it can absorb a lot of moisture. When this is expelled it tends to cup quite a bit. I've had pieces literally curl themselves off the table while milling them. There are ways to mitigate this; one being gluing up two thinner boards with opposing growth rings. Being that you need two of them for each of your speaker halves, that method would be the way to go. 2. The wall thickness on those speaker halves 6mm) isn't enough. I would offset the walls inward another 3 or 4mm to give you more surface area for gluing. 3. You might want a small lip on the speaker halves so they fit together nicely. Keeps them aligned. Let me know what you think.
my wood working skills is just common diy i have in the past made cabinets and desks but not really an expert ,i had not considered any of those points, the speaker design was based off what ever boenickie has on their site and of the various pictures posted on the diy audio as for lining them i was hoping to use dowels to keep them lined up when gluing these are the off cuts i had left from desk i want to use
Ooh are all the offcuts the same as that? If you look at the end, you can see it is made up of several strips, instead of one big wide piece. Are they all like that? If they are, that,s great, because the strips are all opposing growth rings, so it should stay nice and flat. Dowels are a good option. I would still widen the walls a little bit. I wouldn't think it would hurt the sound at all. You'll be doing the gluing, sanding, finishing yourself, correct? If so, I'd be happy to help.
Just saw the images on the diy audio forum. They've also widened the walls. That thickness isn't the same as the 3D model. Good stuff.
yeah they are all like that, was large peice that was not flat pretty much did my back in using my dad really old draper planer to flatten it when i did the desk i will widen the walls in the model i did and yes i want to do the finishing my self
Yes that looks much better. How do you want to do this? Send me the wood and I'll flatten them, glue together and then cut them out for you? How soon do you need it?
Et voila. Just a couple of bits of oak I glued together. They were quite warped, so by the time I'd flattened and glued them together, the total thickness was only 50.5mm, so this test piece is about 1.5mm too thin, but for the purpose of the test, it's fine. For the same reason, I haven't drilled the dowel holes or recessed the outside face for the speaker. Ignore the knots. The tweeter hole will need to be cut with a handheld router once two halves are clamped together. I'm working on a template to make it easy for me. How are you planning to hold the two halves together? Dowels work for alignment, but they don't pull the two halves together. I see the two metal plates in the 3d model. Do you want me to cnc those out of aluminium for you?
oh my that is sweet, and yeah dowels for alignment and was thinking of gluing with plenty of clamps until dry, as for the plates if it no trouble then yes that would be great.
