Building lathe/mill in cast of concrete?

[John McNamaraParticipant @johnmcnamara74883]

Hi Steve

Hermele Germany make state of the art CNC machining centres from “mineral castings” sometimes called “Epoxy Concrete” or “polymer concrete” nearly all their machines use this technique great images in the brochures show the methodology.

Cheers

Have a look through the PDF’s here………

Hi Guys

 

I was delighted that this topic I posted many months ago re-surfaced! With more Chinese made machines saturate the markets one may wish to make instead of buying. Hence I strongly believe that this trend will pick up eventually. Though it was a lost trade. With the new selections of better concrete to withstand vibrations, one can build almost anything!

 

Hopefully along this line some MEW members would come out new products and share around so others can pick up and improve a step further…

 

Once again, thanks so much for the contributions, still on a learning curve.

I’m a member of Gingery yahoo forum, lots of tips there too. They cast alloy lathe/miller/shaper from their backyards. Most of them are from America.

Reading the post about vibrating concrete with a hammerdrill and a hardened dowel reminds me of how I vibrated some concrete for some fence post bases. Remember the old Black and Decker sanding attachment that clamped onto the nose of the drill and was driven by an eccentric that screwed into the nose of the drill once the chuck was unscrewed ? I used this screwed into the chuck mounting , without the rest of the sander and bolted a piece of scrap steel bar onto the side of the drill using the alternative handle mount tapping. Ran the drill in fast gear and dipped the bar into the wet concrete.

Vibated like the dickens and worked beautifully producing some very strong post bases.
