I am looking to set up a small surfacing lab and need some good advice.
My initial investment would be around 30K and I plan on running 50 jobs a day that could go up to 100 within one year.
The mix of materials would be 70% CR39 and 30% 1.56.
About the equipment, I know I am on a tight budget and that narrows down my options…
I am considering a used computerized lens generator – could be a Vista or SGX – , two used Toro x2s and a brand new LOH style blocker.
And this would pose my first question: Is it possible to replace or modify the generator´s chuck in order to match LOH´s blocks? Also, if I replace the chuck on the SGX, would it still be able to cut foam laps? And what about LOH´s prism rings? Could I use them on these generators? I like LOH´s prism ring system. When it comes to repeatabilty, I believe it would be far more accurate than electronically generating prism. Besides this, I plan to do the maintenance myself. I would like to know how tech friendly these generators are when it comes time to do the fixing. I do lens edger maintenance and repair most of the time and I am not worried about fixing issues . However, I do worry about buying somebody else´s problem. What about spare parts, service manuals, diagrams and exploded parts views? Is any of these generators way better than the other?
Should I stay away from any of them?
Most of our electrical outlets are 220vac single phase and we also have some 380vac 3 phase. Would this be ok for this kind of equipment?

I wish I could afford a V50 or V75. I cannot right now, unfortunately. I have to add freight, custom duties and taxes and my landed cost would easily climb up to 50K+ …
I know 30k is not much money but it is a start. I would very much appreciate your recommendations in order to get the most out of it.
I look forward to your input.
Fabian.
