Making a Polishing Tool

Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool Moving into the basement, Ray is pouring a polishing tool using AccuLap compound instead of pitch.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool You can see our layout for making polishers here: easy bake oven, tools and gloves and cartons of Gugolz.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool AccuLap is a clear compound with properties similar to pitch.
Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool Ray has melted it in the oven at 160 degrees and pours it into a lap mold. His mirror is face up under the mold.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool The puddle of AccuLap expands. Ray is making a 10" polisher for his 14" mirror.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool This synthetic polishing substrate was developed for consistency, low volatile content, and resistance to degrading.
Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool AccuLap doesn't harden over time or with reheating/reuse. Ray thought he would give it a try.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool Here he is filling in the mold squares around the edge of the tool, which is plopped face down on the AccuLap.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool Nice tool! Ray is using a 10" disk of Zeodur that he has laying around, probably the finest zero expansion glass in town.
Stellafane Telescope Making Class Session 6 held on March 5, 2016 Making a Polishing Tool The finished product. Now get to work.

Meanwhile, Back Upstairs in the Workshop

Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop Phil keeps an eye on his students.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop And makes a point about figuring to Glenn.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop Doug is figuring a fast 10" mirror.
Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop An accomplished ATM, he is known for quite precise work. How about this beautiful mirror and pitch lap?	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop That's how it's done. Doug was elected a member of the Springfield Telescope Makers tonight.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop Jessica is patiently polishing.
Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop Sharing a laugh with Dave, Jessica also joined the STM tonight.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop And back to work she goes. Round and round the barrel, where it stops nobody knows.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop Keith is figuring a 6" long focus mirror, and is here heating up his lap under the lights for some pressing.
Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop He keeps the lap turning under the heatlamps to avoid melting the pitch.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop Keith started the day by giving his channels some attention, widening them with a razor blade.	Stellafane Telescope Making Class Session 6 held on March 5, 2016 Meanwhile, Back Upstairs in the Workshop Lots of hot pressing needed today. It can be just as hard to land a good figure on an f/9 as any other focal length.
