What is the difference between tabs and no-tabs?

i have always worked with tabs, but it seems to me that not everyone uses them. why not, and how do they manage to attach the pieces without them? whats the difference, and is one better than the other?

A tab on one piece makes the piece being joined to it overlay it so you get the cut end of the part showing and an elevated area. A lot of people use joining strips which is like you cut the tab off then use a strip that is about twice as wide as the tab and glue half of it to the back of one piece at the joint then glue the other piece over the other half of the joining strip. That allows both cut ends to butt up to each other and does a better job of hiding the joint. Joining strips are also handy in closing a cylinder or cone.

Sometimes, especially in extremely small parts, a straight butt joint without any tabs is the way to go. Just run some glue along the edge of one piece and then hold the two pieces being joined until the glue sets up.

It does not really matter if you choose to stick with the tabs. Just a matter of choice.

Well said Doug. If I recall, there's also a great illustration of the general tab/no-tab options on the Digital Navy Website. (but I defer to your expertise in small part joinery....I'm still working on that)

For me. some tabs are in the way, especially in the smaller pieces. I tend to cut tabs and make my own joining strips or I laminate the pieces in order to get rid of the tabs.

The joiner strips sometimes make easier joints than tabs. If you're joining two cylinders or conics with tabs you must rely on printed lines or eye to line them up straight. If you glue a joiner strip inside one piece it guides the other part into position and the edges of the two parts butt up against each other, automatically aligning the joint (provided your cuts are straight).

Hi,
I always cut off the tabs and edge join all parts, then build up the flimsy structures with more card glued on with PVA glue, internally and of course, one piece over the join to internally reinforce that as well.
Enough PVA glue (woodworking Glue) as you would find on the back of a postage stamp, on both surfaces to be joined. It does not matter if one side is dry, as long as the other side is wet. Clean hands before gluing parts together with water from a tap.
to avoid unsightly marks on the outside skin.
BigBenn,

Is it possible to do no-tabs without joints? Or is that a stupid question?
