“having a lot of trouble getting them to sit upright” - I use the same type of tool holders as for beading tools and fix a piece of hard 2.5mm brass rod inside. I file it to a blunt point and use it to press down the stones into their holes. By pressing down at one side or another, I can change...
I would not dare to use machine drills made from carbide (the one with the red marker ring) in a handpiece, as they break like glass. I use tool steel drills 0.5 or 0.6 mm for the pilot hole, and often have to correct their grind after inspecting them under the microscope.
The enlarged photo...
Hello Meshach, I use different styles of flex shafts. One standard size came with the big green-gray motor, the other standard size shaft (the red one) I bought as a spare and connected it to a really slow DC motor. Both accept exchangable handpieces of european style. The red flex shaft is...
For stone setting I use only flexible shaft tools at low speed. Position of the stone marked with a deep dot from a scriber, I drill first a 0.5 mm hole through the metal with a spiral drill. For the rest of the work I use round dental burrs, got tons of them from the flea market and collecting...
I‘m a german hobby goldsmith who engraves a bit as well. Live in France at the german border and work as an electronics/RF engineer in Germany. Region Karlsruhe - Rastatt, PM me if interested.

I second the fine degussit stone, I use it with either oil (does not penetrate the stone) or with a polishing compound like Simichrome.
I found all my degussit stones all on ebay (needs patience!!), there is also sometimes a coarse version that is not produced anymore.

It is easy to use a common drill press as a hone, as Shaun Hughes shows at youtube
the drill press bit starts at about 5:30
I used a similiar setup to shape gravers before I built my minihone, as I found shaping the blanks purely by hand too tedious.
For the quality of the faces and angles...
Hello Marius,
I absolutely adore the drawings you post. Technical question: Are they done with AD at iPad, or at Mac? I’m looking for a replacement for Linearity Curve at my iPad, since they jacked up the prices.

Faced with a similiar challenge, I made a pedal that uses a simple two-lever-gear and just gradually opens a squeezed-shut silicon hose to provide a finely controllable bleed valve.
please excuse my German…
No drawing or plans are available, as I made after some coarse estimations on the...
To avoid heel drag when flare cutting, I was aiming for shorter and shorter heels, until I realised that a very short heel makes the graver hard to control and requires lower angles of attack. Else it will dig in. I had not enough freedom for my handpiece and fingers.
I grind now arround 0.2 mm...
Hi,
while browsing the net for 50-60mm ceramic discs for my DIY mini hone, I had an idea. Instead of using a hard ceramic disc for graver polishing, I could use a hard anodized aluminum disc. The anodized layer is aluminum oxide, almost as hard as sapphire or ruby. Fortunately, I have a stock...
So far only for stone setting, where very short cuts suffice.
I‘m just experimenting with carbide-tipped microgravers, shall I try one without heel? They where pretty capricous with heels already, until I polished the heels with a felt wheel (radiused the edges) and polished the face afterwards...
The best translation I found is „greaseproof paper“. It might also be called parchment substitute or vellum subsitute. The type I use is made to wrap sandwiches, as a traditional replacement for cling film. It is made from wood-free paper pulp which was ground with so much pressure the the...
I tried baking parchement paper, it did work by far less effective than the Butterbrotpapier. I found my favorite transfer method, I could just not tell you where to find similiar paper outside Germany.
Cheers
Ralf
just three fresh examples how the "Butterbrotpapier" transfer works. I put varnish on the piece while it was still warm from hot melt glue, so the varnish layer got a little bit thicker than usual and did also stick to the paper.
The scale in the photos is divided in 1/10 mm, one can also see...
My brother DCP printer/copier/scanner makes no transfer at all with acetone. After many experiments with different solvents (aceton, isopropanol, artist‘s transfer fluid, lighter fluid, NC paint thinner, two kinds of brake cleaner) I read that my brother toner is wax based. That prompted my to...
I like all the different scroll designs very much. I would prefer to purchase the file, as it avoids all the hassle with shipping to Europe, customs and delivery time.
Best regards
Ralf
