I hold the pieces together and apply solvent cement but the pieces don stick or stick in only a few places. What am I doing wrong?
A. The pieces may not be tightly together. A ridge left over from cutting may keep all but a tiny corner from touching – scrape off the ridge before gluing. Or the pieces may be meeting at an angle – scrape or file at that angle to create an area of contact rather than just a line of contact, or use a filled cement (tube glue.) Or the cut may be rough which is particularly troublesome when edge gluing – see the question on squaring up edges. The joint may not be getting enough solvent. On long joints, it can take many trips back to the bottle to carry enough solvent to the joint when you are using a small brush.
