I second Ries's suggestion.

Was planning to build a fullrange ELS until I bump into this forum...

Hi guys,
did some new stuff I wanted to share with you.
I used for the first time MM for aluminium cutting. Needed some special parts for a etiquette applying machine in wine industry. I had only some scrap alu lying around so I cant tell what grade it was. I used a 6 mm solid carb end mill with 20 mm/sec and 0,8 mm pass and 20% stepover.Toolpath was some pocketint and profiling in Aspire.Lubricant used WD40.

Second project was a roomdivider made of 10mm mdf.
First profile cutting done with 4mm endmill.

Attachment 8316

I used a 12 mm V Bit with a profiling toolpath, cutting depth on line 3,5mm.

Attachment 8317

This the cut quality obtained going exact Stop modus in Mach3. True it`s lot slower but worth.

and some more of it....some 10 hours later...

and then of course the other side, too...

Attachment 8325

And finally after some 30 machine hours, I used some Linseed oil for finishing the divider. Dimensions 190 x 90 cm.

After such a job I realise even much more what a wonderful piece of Art the MechMate is...Thank you Gerald for making this possible.:)

Very very nice Claus. Just glad you did not have a power cut in the middle of it.

power loss is a big problem in Florida. I had quite an investment in ups equipment. have not had this experiance here... yet :o Hope I didn't burn the cornbread.

Claus, those look awesome! my wife likes them too!

Claus, Nice work! Now my wife wants on now....lol

My wife and kids are allready making me a list of things to make!

Good looking work!

Cheers,
Travis

Very, very nice work!

Looking good Claus, it appears you have your machine dialed in perfectly.

AWESOME!

got to complete mine ASAP....

Claus, in #169 you were having a little static charge issue on the outside of your dust collector boot on your MM. I was wondering if painting that section with aluminum paint (or other conductive paint) and grounding the paint appropriately could help dissipate the static issue.

Well Done. It looks awesome. :)

did you place tabs in between - and after removing the inner material _ ai am assuming you have run a cleaning pass, thats how I do it, unless you have a order for a 100 numbers and you can build a jig to hold the job and let the pieces drop down :)

Thank you all,

Kobus, having daily problems with electricity I learned from you that making a small hole outside your workpiece, where your zero is, can save your work, and you allways can restart from there...!

Yes Irfan I had tabs, but those were cut away with V bit, imagine sanding about 300 tabs by hand...:eek: Hope that 100 piece order drops in some day, then I will come back to you to explain exactly how to build a jig.

Have all a nice weekend.

Very impressive. The V bit to cut away the tabs was an excellent idea.

What was your feed rate?
Did you go slowly as it was your first attempt?

Jason

Very nice Claus... Can't imagine MM working 30 hours continuously yet.
Can you explain a bit how you generate the divider pattern/software (of course if its not a trade secret). I too wanted to make one for me :)

I do make a small cross somewhere outside work using a sharp engraving V bit before starting any work as you can never be sure what happens next !!

Esti foarte tare :cool:!!! Trebuie sa-ti dau tel unora din Buc care vand un grund special pt MDF. Altfel o sa te chinui f mult daca nu dai inainte cu grund. Cauta oricum pe net firma Goulda SRL. Sigur au site. Eu de la ei iau tot ce imi trebuie pt finisaj. Au marfa de super calitate calitate. Nu o gasesti in hipermarketuri. E industriala si e Italia. Cred ca am zis tot. Si ce e mai important e ca te ajuta cu sfaturi, sunt f amabili.
Bafta,
Marius

Jason, my feedrate was set to 3600 mm/min, but as I said before Mach was set to exact stop and therefore it went very slow, mostly not going over 400mm/min. Only when it had to cut a straight line speed went up to about 1500 mm/min.

Anil, the whole job took about 30 hours, divided in 13 hours of cutting out the small pieces and then another 7 hours for V encgraving each side of the panel. The machine stops were about 30min for changing tool, cleaning table, loading up GCode and pressing start button.

The easyest way to generate a pattern is to use Inkscape, and import some flower and deco patterns which you can arrange to form the first quarter of your finished pattern.It is also very helpful to use helplines in your sketch for aligning all patterns to have a nice geometry.When done simply mirror it sideways and downwards and you have your big pattern. Then you can multiply as often as needed. It is very important to use vector graphics as they are scaleable to any size. Hope that helped.

Stumbled across this link a while back on the mechmate forum, cannot remember which thread but it was saved in my browser favorites.
Scroll down the page to find the patterns.

Jason, thank you for that link.
Indeed there are tons of patterns. I found the one I used in a vector pack on file sharing server together with many other vectors.
The trademark logo from craftsmanspace was also removed. intresting...

It was 'Clean' Vectors - free project plans for the woodworker

Rectifying Brass.

This is a part of a wine bottle labeling machine. The part I had to rectify is a leveling device for the glue applicator. Having an age of about 30 years it had lots of dents and hits on the surface which normally has to be smooth.

That´s the result. Thats the upper part which had to be chamfered 45°. I used a V Bit. Then with an endmill the cutting edge was straightened.

Then turned it around. Thats the underside which was worked with a 8 mm endmill.

This is my first job where all was done by manual control of the MM.

Claus, do post a pic of the completed speakers.
Here are some nice BLH CNCed speakers from Andrew Tisley -

http://www.creationaudio.com.au/Products.html

They have some nice designs. I especially like the compination of layered birch with acrylic panels. I also had a nice link from one japanese diy-er and will post it when i find it.
The MDF speaker was just a prototype to see if everything fits, the product will be cut from layered Birchwood panels around 20 mm. I will use Fostex chassis from the sigma series. I`ll come back with pictures.

Hi guys,

I was pretty involved in some little projects lately. Soon my webpage will be ready for presentation, and of course I`m working on the content.

Here is what I`ve done lately from 25mm layered birchwood panel:

I will post some more work soon, as ti will be finished...

I like it! :)

Very nice Claus :), how the glass is held on, is it glued somehow ?

Anil, the glass is just heavy. Size is 2.2 x 1.3 m and thickness 13mm. Gravitation is doing the fixing. But of course it possible to ad some rubber or felt pads...:)
