"CERRO PICUCHO "
My name is Enrique Hernández , I am a partner and director of the Association of Amateur Astronomy Uruguay.
Back in early 2003 with Walter Fontana (aka " Picucho ") began the arduous task of carving a pair of mirrors of 35cm diameter telescope type Newton.
Walter
already had some practice he had carved a 20cm years earlier and was his idea to undertake this "demonic and crazy" project.
Of course, with such a diameter, the focal ratio of 4.5 could not happen because a tube more than 1.5 meters of these characteristics and would become very difficult to move. The end result, after more than a year of work, was my mirror f4.15, and the Picucho of f4.25
As we delayed both in this great project and my 114mm f8 Tasco equatorial I was doing "boy," he carved in a month a 23cm f6, which became my 2nd portable telescope but Dobson type mount .
After having the mirror of 35cm. early and waiting for your aluminized , I made the idea of \u200b\u200bmounting it in a fixed observatory.
After some "negotiations" with my dear wife, I managed to get me granted the usufruct of a small space in the back of my home (2.40x2.40 m)
The construction began back in late September 2006 with the great help of my son BRUNO less than 3 years, starting with the foundations accordingly. (To think that Bruno was in the belly of his mother when I started roughening of 35!)
At the time of writing (almost 2 years later) I'm about to put the roof sheets.
it for now and accept criticism and / or advice.
- Cutting and carving the telescope mirrors
first thing we needed was to get plates or glass tiles as sufficiently thick to cut our mirrors. We got
demolition houses priced fairly accessible.
demolition houses priced fairly accessible.
Plates and tiles 25mm thick where to cut off 23 and 35cm discs.
35cm hand tool. It took 3 hours to cut each disk
Stone for bezel, curved plate to f4, water sprinkler and No. 45 emery
Starting grinding with carborundum No. 45
few months later we set up the cake of pitch ( tar and resin)

I can not complain ... My wife helped me much!
