When using tab and slot to hold your pieces together, what do you use to clean up the corners of the slot? Just a chisel, or is there a more convenient way of squaring up the corners? First post here, ordered my kit a few weeks ago. Busy cleaning out a spot for my maslow once it arrives. r- ---

Welcome, if you have cash, one tool can cut tabs, flush-trim and sand. If you prefer hand work one of these “are they called Japan saw?” ---

I do own a sonicrafter, but I’d thinking of a different type of tab… I might be using the wrong term or just not explaining myself properly, sorry. What I’m thinking of is you cut a square hole in one piece and a square tab on the edge of another so the two pieces can be put together. The corners of the square hole will be rounded since the cutting bit is round but the corners of the tab are square. I’m asking what do people use to carve out the rounded corners of the hole so the square tab will fit. And yes I intend to glue the pieces together. thanks, sorry for the confusion r- ---

Are you familiar with dog bones? Basically with CNC you overshoot corners so that squares can fit. ---

So for this, enemy board or sand paper, fine wet sanding, then glue. Use wet paper towel or sponge to clean up excess glue. Thank you ---

Yes, a Japanese hand saw, or a 3/4” (or larger) wood chisel (keep it stored with its protective sheath would do. Sanding is always a good idea. ---

It is a question of the angel of bit you use and the type of bit. Most of what I’ve seen is a jig cut or 90 degree sideways cut. Thank you ---

This might help - > **[Woodworking joints](https://en.wikipedia.org/wiki/Woodworking_joints)** > > Joinery is a part of woodworking that involves joining together pieces of timber or lumber, to produce more complex items. Some wood joints employ fasteners, bindings, or adhesives, while others use only wood elements. The characteristics of wooden joints - strength, flexibility, toughness, appearance, etc. - derive from the properties of the materials involved and the purpose of the joint. Therefore, different joinery techniques are used to meet differing requirements.

Thanks everyone. I’d talked to my father about it (he is actually a woodworker, unlike me, I’m just a guy with some of the tools). He suggested everything mentioned here as a possibility. I decided I’d ask here if there was a best tool for the job. The information about dog bones is very useful and tells me I need to put some effort into learning fusion360. I’ve never used a real cad program until last week when I taught myself the very basics of librecad. Now I can at least draw up my ideas. Next step has to be going to 3d. randy ---

dogbones can either be at a 90 degree angle (you have to go half the width of the bit), or at a 45 degree angle (where you only have to go .15 bit width) look at what the can program you use can do. Makercam can’t implement dogbones for you, but you can create them in your drawing before sending it to makercam.
