Thomas,

My apologies.

The pictures look so 'immaculate' that I was sure they were generated from the 3D CAD design.
The workmanship is so good and it is finished off so well that it looks like...

Hi Thomas,

That looks really professional.
Is this design also a two part design?

Do you have any pictures of the real machine yet?

Sandi

Castinite,

That is very impressive.

Your last few posts have been very inspiring. Makes me want to go out and build something.. I am very amazed at the accuracy you achieve simply using wooden...

Digits,

I do board design all the time, send me a PM if you would like some help with this... It is not that difficult..

Regards

Sandi

Eric,

Great, thanks.

Just one question regarding synchronizing the two motors. How do you intend to synchronize, or rather shall I say, control the angle of two motors relative to each other?
...

Eric,

It's been a while since I've posted here..

I am quite interested in your work. I am curious to see how much this table will cost you and also what the results will be like.

I have had...

Don't forget to include the dimensions of the ball screw nut.

Sandi

Lazlo,

You are correct, I initially though it was EQ.... but then edited the post (on the bottom)..

It is still an interesting project.

Hello all you guys out there...

I came across a very interesting CNC mill design built on an EQ table....

Looking good! :)

Guldberg,

Just isolating it will do the trick.
But the best solution would be to remove the 'shroud' around the transformer, these transformers are usually mounted on one side only.
Did it not...

Talking about Walter, does anyone know what happened to him?
He simply disappeared.

Will,

I did not think that you were planning on infusing the epoxy into the aggregate when you mentioned the low viscosity epoxy, I was just voicing my opinion and understanding of EQ...

Will,

The people on the German forum 'Peters CNC-Ecke' "discovered" that the EQ should be vibrated in a linear manner and not in a circular manner. They built a vibrating table that was pivoted at...

Hi John,

Wow... I was not expecting that... I was also under the assumption that we should not have a problem getting quartz..

Well, the supplier that I have sells 3 or 4 sizes of sand, which I...

Cameron,

Regarding the size range of available aggregates: What if you were to sieve the aggregate yourself into (more than 3) size ranges?

Really good work on the epoxy there, thanks for all...

Hello guys,

I have "no" machining experience when comparing to you guys, and for that reason I 'prefer' what NC Cams has suggested.

I don't have the experience or know-how to do what Steve has...

Steve,

Exactly which rules are those? :-)

Sandi

Hi Bruce,

My results were a little disappointing. But that is due to the simple, limited, method I used to make the samples.
The samples were small, hence difficult to measure out the correct...

NC Cams,

Thanks for that info!
You have gone and nailed my question square on the nail.

And you have given me some VERY valuable info, which I never thought of before but is logical when I...

Hello Bruce,

Yes, the Germans do some impressive work.

I also experimented a little with the EG mixture closer to the beginning of this thread, and I used the Epoxy the Germans use: L1100 from...

Thanks jmorris for that bit of handy info.

Sandi

Thanks guys for your responses.

There is one thing I am also trying to figure out; Is it required to harden surfaces on the spindle and housing components or not?

If hardening is required, does...

Hello,

I am looking at spindles and their designs.
I know that a good spindle design needs to take temperature and COE (coefficient of expansion) into account.

I read that high-nickel steel...

Hello Chris,

Welcome aboard.

I myself have not posted on this thread for a long time now because I am dealing with the same constraints that you have...
Time seams to simply disappear when you...

John,

Could you tell me where you bought your sieves from?

I am trying to find a seller locally here, with little luck...

I have not tried finding a German supplier yet though..

Thanks

Jeff,

I am not familiar with that platform. I designed developments boards (A4 page size) with FPGA's and tons of interfaces/peripherals on it.

No, the problem with the USB to JTAG interface is...

Hey guys,

I design FPGA systems (PCB's) for our development team.
I used to work for the guy who started the Opencores organization, and I still work with many of the guys who wrote some of those...

John,

That photo is very impressive. The bands are a little bit of a concern..

What would happen if you reduced the epoxy content, and thus reduce the possibility of segregation?
I imagine...

John,

Those samples look incredibly dense (or should I rather say compact).

Very impressive results, I would love to see some close ups of the EQ, and also some close ups of breaks.

Regards...
