Even if fingers joints can be easily machined on the spindle moulder, they hold at least two drawbacks. The main one is about grooving the four sides so that accommodating the bottom. Two sides require dropping-on operations and consequently the bottom to be adjusted. The second drawback may turn into a benefit related to need and demands an applied moulding or face screwed in front of the drawer. The following assembly enables for blind finger joints from the front and does not require dropping-on operation.

Here is my version of the Jmb24's drawing. Face and back are square with forty five degree fingers whereas left and right sides are mitre cut at a forty five degree angle with square finger joints. The drawer face need to be slightly thicker than the sides so that joinery could not be seen from front.

So it was time to experiment that joinery and I first cut faces and sides as described above.

But before going further I devoted some minutes to think about the quickest process of machining the whole drawer joinery. A stack of grooving cutters should allow for very accurate finger joints and grooving as well as rebating the bottom. Besides their five millimetre kerf would increase the finger number enabling for more contact surface at sticking time and I should merely have to level the bottom teeth flush to the top table then once rise five millimetres and once twenty five millimetres for the whole fingers to be machined.

What follows doesn't match the above process but seems more natural. So I piled the cutter stack then adjusted the scaled fence with a sacrificed block at forty five degrees and went first through the working tool.

I lifted the head cutters twenty five millimetres and turned the workpiece upside down to machine the other side of the front face. As you may see below I milled two identical faces rather than a face and a back. That way, if something went wrong I could probably have fixed the issue.

I lowered the cutter stack by twenty millimetres then formed the sides fingers with the scaled fence at ninety degrees.

I kept only a grooving cutter on the shaft then set up the continuity plate and machined the grooves aiming to accommodate the bottom, right at the level of the second finger. Here no need of dropping-on operation since this is a forty-five degree joint.

It was time to rebate the bottom wich was slightly thicker than the groove. The above grooving cutter allowed for that work and the bottom didn't need any other adjustment since no dropping-on operation modified the groove depth.

I made a dry assembly then stuck the drawer sides with white glue and without any clamping.

It remained the joinery strength test of that assembly looking like right finger joints but mitre joints at forty five degrees in the real world. The front face held 128 Kgs (280 lbs) in the below photos and I was under the impression that drawer structure could hold much more.
