Thank you to everybody who contributed to this subject. I purchased PVC pipe glue (based on MEK) from my local hardware store. It works great! It appears to be prethickened so is easy to apply. I used a toothpick. It is strong enough to firmly join (...) (25 years ago, 4-Jan-00, to lugnet.robotics)
