The Emblaser comes with a small satchel of Super-Lube. You only need to use a very small of the grease on the bearings. Too much will just gather on the outside of the bearings and collect debris. This will eventually find it’s way into your bearings and do more damage.
With respect to the JTech optical acrylic we could not find any test report data on this product from their website. Stating an OD with no test reports to back it up is not something we can support.
Our ‘in-house’ tests using the appropriate test equipment showed that 4.5mm red or amber tinted acrylic provided approximately an OD4 rating. Regardless of this we cannot legally sell this acrylic stating this protection level tested by an accredited test lab.
For the Emblaser 2, we are having a completely custom acrylic formulated for our specific requirements. This has undergone all appropriate testing by accredited test labs before being deemed to satisfy all required country’s standards.
