Tom Eltang rustication technique

kasperbunk · Post by **kasperbunk** » Wed Jun 26, 2019 6:59 am

Does anyone one this forum have any clue on how to rusticate like Tom?
I really like to hear how he does this? Is it a combination of rustication (dremel) and sandblasting?

What do you guys think?

I suspect that is dremel carving plus sandblast as you surmise.
I saw a couple of pipes by Werner Mummert in Chicago a couple of years ago that had a very similar appearance.

High torque, low speed rotating abrasive cylinder for the major grooves & shape; touched up with smaller, medium speed cutters as necessary; finished with a light blast for textural uniformity.

Step one is the same technique Lee Von Erck does for spiral-scooped panel pipes, just narrower.

I looked at this surface more closely under magnification, and it actually appears to be chemical etching applied after the rotating cutter shaping.
This was discussed recently and the surmise is that either a moderately powerful basic solution such as lye (sodium hydroxide) or a moderately powerful acid solution (concentrated acetic acid) was used then washed off.

I know there are a few Germans who mess around heavily with the chemical etching thing, so it's entirely possible (and could definitely replace blasting) if perfected. A really "toothy" rotating cylinder + chemical erosion would be two steps instead of three, besides. Make more money $en$e.

What I described is how I do it when replicating his finish (I use 3M bristle brushes instead of true sand, though), so know you CAN get there that way.

Latakialover. Could you maybe give me any advice on what tool on the dremel I would want to use? Just a hint:-) it seems to me that the ball headed tools are to small i diameter?

No go on a self-powered rotary tool. Take forever & probably wreck it.

Mount the cable-end of a Foredom tool in a drill press chuck, and set the DP to its slowest speed.

Great advice! But what tool bit du i have to use? Any thing like this?

No. A sphere will just walk around, and maintaining a (relatively) uniform depth would be close to impossible.

Use something more like this (though longer would be better):

Ideally, MAKE the tool. Grind deep, sharp, raggedy-nasty teeth randomly into the surface of a HSS drill bit that's been shortened to the exact length you want, and whose shank has been ground to fit the chuck of your Foredom hand piece.

I maybe think this one could work at very slow speed. Tried it in the drillpress. Seems to work. But hard to follow lines

What's your point?

Gee... I dunno...

I was just moved to repeat the word "practice" three times for no reason.

Impossible to explain... LSD in the air, maybe?

It's like I tell my 4-year-old all the time - there's a difference between knowing how something is done and knowing how to do it

Dont be too hard on me guys! I know practice makes master, and i know there are no shortcuts. Just trying to find the right tools and NOT reinventing the wheel:-)

I agree! And I'm not being hard on you - I need as much practice as anyone

My eyesight is bad, but it appears that you are using sanding drums. I believe the Saburrtoth burrs might be a better option. http://www.saburr-tooth.com/ They are available in different shank sizes and all kinds of burr shapes.

No sanding drums. I am using that thing you are linking to:-)
