"Is this the design with the bearing ball providnig vibration? How did it work out for you?"
-Yes it worked pretty good but when the molds get bigger you really need a strong vibrator.

"What were your thought about putting the unfinished side of the EG saddle uppermost? I would have thought that the unfinished part of a mould would be better hidden below."
-It would have been nice with a smooth surface on top but the angeled surfaces underneath forced me to do it this way.

"What was the mould material? What mould release agents did you use, did they work well?"
-I don't know what its called in english but its a wood-based board.
I painted it and then waxed the surface but the damn thing wouldn't come loose.. I ended up smashing the mold :tired:
So its a no on the last question

A small note,
Its only the plate between the X and Y axis (or do you say axes?) thats made of E/G

You should try entering this into the cncmentor.com build log competition! Nice work!

Thanks for the answers.

I think that is the same experience everyone is having, that they need to kill the mould ot get the bits out.

[sahilkit]

that's a nice machine thewho, i'm interested in knowing what size stepper motors you have any Spec would be nice and what kind of travel speeds are you getting ? by the way how much would that saddle along with linear rails, bearings, plate, motor etc. weigh ?

Started on the enclosure (it's still not completed..)

Then I was going to mill a new nutholder(?)


But


Then I started on a R8 spindle with TTS.




Got my new table.





Ready to use

The old mounts.


Next post will be about the R8 spindle.

Done!


Next is the R8 spindle shaft.

Damn, some measurements was wrong in solidworks..

Didn't have any round steel..

Assembly





Tried to take better pictures.

Now it's your turn to add some posts then I will continue at page 6

I think you let us speechless... Awesome work, and that spindle looks impresive!

Is the connector on the body for air or oiling? I'm not familiar with this kind of taper, how is toololder retained? i see no springs or anything in your photos.

BTW, i'm working on a E/G machine too, for his one i've used a gantry design, but the next one, will be like yours, i really love the way you're geting things done!

Please, more updates

[thewho]

It's for both cooling and oil, and I hope the air pressure willl keep chips away from the bearings.

It isn't much of an E/G machine after all (was going to put a smiley here but this forum doesn't have any useful ones..)

nice spindle

[TOTALLYRC]

Looking good!!!

I think "holy crap!" captures my response the best.

[christofer]

What kind of seals do you plan on using to protect the spindle bearings? What kind of spindle bearings did you use? Do you recall how much clearance you have around the spindle bearings in the housing?

Looking great!
