Concrete carving suggestions

I've used a lot of it as an accelerator/additive for plaster...and it gives an almost ceramic finish. Too brittle for lamination processes in my opinion. Concrete...not so much experience. I have som…

you've probably tried this....but i'll pipe in anyway....i find a typical face coat mix ie. small agg, and silica fume produces a zero slump clay type mix. no additives also. probably end up with som…

form and pour (wet cast) GFRC... question

hmmm.... this may be off topic for this thread...but... PVA is hard to get to flow? Even when heavy with the super p's? this is valuable information. i'm guessing you need a very heavy fiber load wi…

Doug Chambers replied to Ryan Waxman's discussion 'ceramic cements. Anybody interested in trying?'
fascinating. it bonds well to metal? how well? You mention wax....like mold wax/mold soap? how 'bout form oil? haven't recieved an email....are you still going to make samples available in the denver area?

Doug Chambers replied to Eciton's discussion 'form and pour (wet cast) GFRC... question'
thanks for the reply. i understand GFRC is technically just glass fiber reinforced concrete/cement......but most of my experience with it is for lightwieght castings and not countertops. that being said...i do like the idea of a single pour. no dela…

Doug Chambers replied to Slab-Fab-Studio's discussion 'Super cool sink shape and idea...'
admittedly, after a more intense look... this is obviously a case of a designers render. many can appreciate the gap between design and fabrication. cool concept though. the mold design for this thing would be quite complex even with a tremendous am…

Doug Chambers replied to Eciton's discussion 'form and pour (wet cast) GFRC... question'
I'm having a hard time getting my mind wrapped around the idea of GFRC without a spray coat. Admittedly...i'm no expert, but my introduction to GFRC was a spray coat without fiber....backed with a fiber lamination layer. In this instance you still h…

I've found this book on this matter. Hope it help.

Doug Chambers replied to Doug Chambers's discussion 'Fabric Forming conference vids'
yeah...thats the one. i think i read somewhere he stiffened the fabric which is an interesting approach at mold design. all the fabric forming i've done has been very organic....utilizing the material properties of the fabric to produce desired resu…

Rich Holschuh replied to Doug Chambers's discussion 'Fabric Forming conference vids'
The hand-print sink referenced may have been the one by Brandon at Gore Design. Nice design and in GFRC I believe... Yes, there is a difference, as Alla said, between sink casting with a stiffened fabric master and the U of M work which is direct fo…

Alla Linetsky replied to Doug Chambers's discussion 'Fabric Forming conference vids'
There is a big difference between using fabric to produce a rigid mold (or sink plug) and using actual fabric for forming. The handprint sink was made from fabric that was distorted and stiffened. The U of M guys are using flexible canvas to form th…

Doug Chambers replied to Doug Chambers's discussion 'Fabric Forming conference vids'
ahh....you never know inspiration and all. i think i saw someone around here produce a pretty cool sink with an impression of a hand print in a sink. Also...i've seen a few images of full counter tops cast with fabric. May not be your thing but its…

I am letting folks know I have a small web site set up to sell samples of ceramic cement, calling it Bombercrete. For large orders you can just call me and i can arrange however much you need. I am suggesting people start with the Premix, I am selling it pretty cheap and its the easiest to work with.
