Chuck demonstrates how to establish Fixture Time for the material
using UV curing adhesive on glass plates.
Regardless of the adhesive chosen there are some basic steps in project design, part preparation, and adhesive application and cure to insure a long lived project.
Overview – Adhesives are another tool available to help make the assembly of materials easier. However, to get the maximum benefit from their use you must play to their strengths. For the following discussion the adhesive is assumed to be OK.
The adhesive is only as good as what it is stuck to. Surface cleanliness is a must.
Make sure you have a simple test to insure the adhesive is working properly
Make sure the components are the same each time – substituting materials or a change in supplier needs to be re-evaluated – do not assume they are the same.
Hand fixturing induces lots of variability in the ultimate performance – simple fixturing and clamping will eliminate a major variation in performance.
Once the adhesive has been applied, the parts assembled and fixtured don’t handle or try to readjust things – most adhesives, regardless of how quick they set (with the exception of uv cure materials) continue to develop strength for several days – this includes super glues, 5 minute epoxies, etc. Make sure you do not compromise performance if you need to handle parts soon after assembly.
