Si si questo lo avevo capito, non mi era chiaro invece se la statistica andasse fatta intervenire anche nelle c.o.c.
@Massimo grazie mille, riuscirei a costruirlo (perhaps) ma dubito di riuscire a leggerlo nel modo corretto quindi quando sarà ora magari posterò i risultati
@Giulio quindi nelle passate C.O.C. quelle che meglio sopportano il seppur minimo debordo laterale sono le 1/3, quite right? Quindi significa che non devo superare il bordo per più di 34mm per lato giusto?
hello Giulio,
Innanzitutto grazie per il tuo supporto sempre presente!
Lo specchio inizierà ad essere lavorato a settembre ora sono in “raccolta materiale” ricapitolando quello che ho:
– 4 dischi calciosodici da 203mm già bisellati
– fusto olio esausto da 200lt
– gesso e dadi per realizzazione utensile egualdiametro
Quello che manca:
– carborundum, dopo aver letto ho optato per questa sequenza 80-120-180-320-500-800 with 80 a scavare quasi tutta la freccia
– pianale tondo per il fusto dell’olio (devo trovare qualcuno che faccia tagli tondi da 580mm oppure faccio un quadrato e lo adatto
– pece ed ossidi per lucidare.
Purtroppo non ho modo di avere accesso ad un test di focault o di Ronchi, questo mi frena ma se trovo qualcosa in rete (in Italian) provo a costruire io qualcosa.
Parto con passate cordali per scavare la freccia, poi una volta a misura? Specchio sotto e c.o.c. con le grane più fini fino all’eliminazione dei crateri?2,5kg for casting a disc 200 x 30? Not with 2,5 There kg colavo 100 fingerprints! They dental practitioner even if not I'll go in my old workshop to take it
Yes sure, I also would use type IV plaster for stumps and fixed prosthesis, It is the hardest. A memory temperature is reached between 45-55 gradi.pensavo to do so for a 30mm thick 20 cm, what do you say? The nuts I galore from M8, They are too small?
PS I I bought 15 euro from an oil drum 200 l…. Another small step….hello Giulio,
then I do not understand anything, I reread everything to avoid errors:
passed chordal to dig the arrow (to be clear that with the center of the mirror which works onto the rim) with 5 go-forth movements, rotating around the table and turning the tool in the opposite direction to each group of go-fro, to speak thishttps://www.youtube.com/watch?v=_gd-is8DBUQ
until the 95% arrow
Regarding the dental plaster would use what type superfirm (the brown one for fixed prosthesis) but dental tell you it does not reach 70 °, Perhaps you confused with the coating for gold melting (they are overcome easily). But I have the mirror plane, with equal arrow 0 I mean, good for digging the arrow or just to finish it? what are the bolts? True that armies chalk to chalk compression but takes the step 2 of the Moss scale.
Excuse the confusion and questions from total beginner…..hello Giulio,
sorry if I answer only now but I messed up a lot on weekends! So in summary….. if the text is in French even worse! At least one bit’ English I did! with regard to the past 1/3 C.o.c. If I understood well have a simple back and forth to the center to work on precisely multiplex, mirror and tool so as to dig at least one 95% Arrow with more coarse-grained (imagine the 80) without overflowing laterally too. The discs are bevelled with the rounded edge of 2 / 3mm'll be careful that during processing and will not be lost in case the renew. And the more 4 discs are beautiful….. sorry sacrificing even one, I read that it is possible to create a tool for dental gypsum and bolts, It is also valid in the creation phase of the arrow or just for further processing?hello Giulio,
As always with the email replies.
As for the text of Texereau I I have some problems with English but I try! For past 1/3 c.o.c (center over center) you mean the classical crossings W? Quite right?
So the motion remains the same from roughing to polishing?Unfortunately I have seen the tutorials and read almost everything but I am someone who needs a tutor, do the job 1 time with a glass scratcher and take notes….. I can't apply the practical from the theoretical just by reading. Some scratch glass in Pavia and surroundings?

Hi Massimo,
but it sure will be, I repeat, I'm not a great parable expert (although I would like to work myself a mirror but I really don't know where to start) mine was more of a curiosity, if for an f9 the arrow is about 1,4mm, it is possible to parabolize it? if it is to be very easy and quick to do I guess.Andrea
jokes aside, there are more worries than enthusiasm
