Lorenzo's apprenticeship

Postby Lorenzo » Wed Jun 11, 2008 8:55 pm

Here my attempt.. not intresting for everybody maybe but i want to show it to Karl because the input came from him.

I used 1mm thickness stainless steel, the only metal in my possession at the moment :crackup: and i did 50x50 because my teacher told me other exercises will be same size.. so i wanted to make an exercise on exercise and i cutted it 50x50.

Despite the camera effect, the sides are flat and in square; nothing drops. If i will be able tomorrow to make a counterlight picture to show the gaps i will do.

I was impressed to see the first exercise completed, Lorenzo...this, 2nd, challenge even more deserving of respect. This is not an easy thing to do, You should be proud...I'm sure you have learnt quite a lot too. :clap: :clap: :clap:

I look forward to seeing both exercises when you visit me in August, then we ( my family ) will put you to the test ;) , not quite what Patrick endured ( he has some years on you ;) ) but I will do my best to draw the very best out of you.

Namaste, Ford 8)

Hi Lorenzo, compliments for the work.

The orange stone under your exercise is a polishing stone?

Yes, it is a D I Y artificial waterstone, double sided. One is 600 grit while the other one is 300. You can buy it for around 7 euro, but i suggest to use a bigger one. Actually this one have a side of around 5 centimeters, same as exercise, so that it was quite difficult to hold it in hands.

Sizes matters :sneaky:

You can use also sandpaper like 800-1000 grit to polish the surfaces?

Yes you can but what you will obtain is only a shiny surface.

The difference between stones and sandpaper is that stones are rigid and (shall be) flat. If you want to keep edges and have a flat surface, you must use polishing stones.

I use the sandpaper for my work whit buffalo horn and I use a container floor, in this way i can keep the edges and a flat surface. :biggrin:

The concept of flat applied to mechanical geometry like this case is a little bit deeper than the flat you can obtain while working with horn jewels. In this case, the surface putted against a square or a ruler in counterlight shall make no light pass through.
