Auf Wunsch schleife ich die Rückseite plan bis K320. Das kostet 15,- bis
30,- Euro Aufpreis, je nach Aufwand (zu empfehlen ab 12 Zoll Größe).
Die Großen machen nur Sinn für Leute, die bereits einen Spiegel erfolgreich
fertiggestellt haben.

Materialbestellung

Ich habe Rohlinge in vielen Größen auf Lager bzw. kann andere Größen auf
Bestellung liefern. Wer Interesse hat, kann mich unter meiner obigen E-mail
Adresse anschreiben oder telefonisch unter +49 / 89 / 62 42 01 71. Bei
Bestellung bitte auch gleich die Postadresse angeben, wo ich hinschicken
soll.

Die Rohlinge sind aus Schott Borosilikatglas. Sie sind auf beiden Seiten
naturblank (durchsichtig und bereits recht plan), die Kanten sind
geschliffen. Sie haben die selben Eigenschaften wie Pyrex oder Duran und
sind schön spannungsarm und schlierenfrei (unter Polarisationstest) und
haben keine sichtbaren Blasen oder Einschlüsse. Damit habe ich den gesamten
bisherigen Münchener Spiegelschleifkurs ausgestattet, auf dem ITV verteilt
und auch viele verschickt. Das Material hat sich sehr bewährt (siehe z.B.
die zahlreichen Beiträge unter Links oder im Astrotreff). Ab 8" Größe sind
sie 25 mm dick. Dicker gibt es leider nicht aus dieser Quelle.

Mirror-sharpen - Workshop
Of Stathis Kafalis copyright ? 2006

| Home | overview mirror loops | Tipps and cheat | typical errors | to ITV Workshop | self's building Munich | the video | material | left |
Material order

I have blanks in many sizes in stock and/or can other sizes on order supply. Who has interest, under my above E-Mail address can write me down or by telephone under +49/89/62 42 01 71. For order please also equal the postal address indicate, where I am to send.

The blanks are from bulkhead Borosilikatglas. They are on both pages nature bright (transparent and already quite flat), the edges are polished. They do not have the same characteristics as Pyrex or Duran and are beautifully tension-poor and streak-free (under polarization test) and to have visible blisters or inclusions. With it I equipped the entire past Munich mirror sharpening course, on which ITV distributes and also many sent away. The material worked very much (e.g. see the numerous contributions under on the left of or in the Astrotreff). Starting from 8 " size they are 25 mm thick. More thickly it does not give unfortunately from this source.
   

The gross of prices zzgl. dispatch are as follows:

Borosilikatglas of blanks:
Diameter    Thickness    Weight    Price euro    Supply
Conditions: 24.Aug.2006
4,5 " = 115 mm    15 mm    0.35 kg    15,- ?    On order

 6 " = 155 mm    21 mm    0.89 kg    36,- ?    Camp
 8 " = 205 mm    25 mm    1.86 kg    58,- ?    On order
10 " = 255 mm    25 mm    2.87 kg    87,- ?    On order
10,6 " = 270 mm    25 mm    3.22 kg    92,- ?    On order

13 " = 330 mm    25 mm    4.81 kg    133,- ?    On order
14 " = 355 mm    25 mm    5.77 kg    160,- ?    For the time being not available
approx. 16 " = 400 mm    25 mm    7.25 kg    200,- ?    For the time being not available
18 " = 460 mm    25 mm    9.35 kg    240,- ?    For the time being not available
More largely, other Duchmesser or thicknesses
(to max 25 mm):    On request

When desired I sharpen the back flat to K320. That costs 15, - to 30, - euro surcharge, depending upon expenditure (to recommend starting from 12 tariff size).
The large ones make only sense for people, which already successfully finished a mirror.

Sharpening and polishing material:
I have sharpening material nearly always available. A complete setset set contains the Schleifpulver silicon carbide K80, K180, K320, Microgrit WCA 15my, 9my, 5my (alumina with specially flat particle shape and accurate particle size distribution), of Polierpulver Ceri HPC (a very fine and pure Ceriumoxyd) and optical pitch 28°. The K80 for coarse sanding is in any case sufficiently for approx. f/5 or more slowly, the finer powders, pitch and polishing agent is plentifully limited, in order to catch also setbacks. Everything is contamination-free separately into double bags packed and marked. Gross prices zzgl. dispatch:
Setset set    Weight    Price euro
 6 "    1.2 kg (0.35 kg K80 contain)    23,- ?
 8 "    1.9 kg (0.7 kg K80 contain)    29,- ?
10 "    3.2 kg (1.4 kg K80 contain)    40,-?
12 "    4.1 kg (1.8 kg K80 contain)    55,-?
I can arrange other quantities at will on request. Silicon carbide granulation 60 and K 120, as well as Microgrit WCA 3 my and 1 my is when desired also available.
Whet-stones to sharpen cost 3.50 euro chamfer (gibt's also in most building markets).

The dispatch within Germany is up to 5 kg 7.00 Eur, up to 10 kg of 10.50, up to 20 kg 14, - zzgl. VAT. Prices for foreign country see here.
