hello

 I have a Trend CDJ 300 Dovetail Jig

 The problem is I never seem to get a tight fit between the male and female joints

Any tips or suggestions would be greatly appreciated

Hi Brian, These type of comb jigs rely on fine tuning the height of the cutter to tighten or slacken the joint. If you use a couple of test pieces, make the joint as normal, and if it is too slack, lower the cutter projection marginally, this will make the tails slightly wider and should tighten the joint. (raising the cutter will loosen a tight joint) You may need to have a few test pieces ready to cut a few joints until you get the fit right. The manual should give you the depth of cut needed, so it should only be a very small amount needed to adjust the fit. A fine height adjust on the router is ideal in these situations. Once you have a joint that is perfect, cut a sample and use it as a setting gauge for the next time you use it and it should eliminate trial and error set ups. hope this helps. Andy
