Wow! How many hours did you spend on the shaper?

Very nice job. What kind of tool bit do you have on the shaper? I can get a small shaper for $200 bucks running with vice but have no room. Its rusting away In a friends shed.

About 4 hours to clean up and square the front face and back face,then trim to length on one end for all. Contrary to the "expert" opinions a big shaper ,set up properly can be very competitive for some work. These T1 burn outs just eat mill tooling ,where 1 cobalt square bit did the entire job with one touch up after a bad crunchy spot.

For burn out clean up my choice is low % cobalt. Make the room they are very useful.

I admire your tenacity but I don't believe you'd ever beat a good 45º lead angle carbide insert face mill for the work of squaring up blocks like that.

Call me a Doubting Thomas but I also can't buy that it really took only 4 hours to square up that many blocks in that manner. I suppose it's possible if you have a big vise and ganged up several parts at a time, and only squared a couple of surfaces.

It's a matter of cubic inches per unit of time material removal rate, and it's my not-so-humble opinion that I could cut your time in half with a decent cutter. There must be a reason that no one makes shapers any longer, or certainly very few commercial shops have one, let along use one.

I will NOT argue that the shaper is capable of flatter surfaces under the right conditions, but the arguments I get for using one is that it's "so mesmerizing to watch" and "I can start a cut and go have lunch." Neither of these sentiments square with making money through productivity.

Greetings Mr. applications engineer, If you had read the text,only 2 faces squared,and one end trimmed to length. Only one cut on each face .One cut on the end trim. After cut depth setting on one block (photo taken here) the rest were ganged 3 at a time on the face cuts and 4 on the end cuts. The weld relief cuts on the bottom were gang sawed 4 at a time in a shop made fixture.
As to your doubts to time ,I can still tell time even at my advanced age and am not in the habit of lying about anything.Could be that 50 + years of owning and running shapers,slotters and at one time a planer plus lathes ,mills and etc help in getting the most from my antique equipment.
Never said a shaper was used because it was faster. For me it is used on dirty,rusty work,one off repairs and burnouts due to the low tooling costs. The milling machines are used on clean work and we try to keep the grit and mill scale, etc off them .This profitable job is a repeat with the quantity increasing with each order. Still making money with a shaper in spite of internet wisdom to the contrary.
You are making assumptions about something with no knowledge as to speeds ,feeds ,depth of cuts etc used here, so they are just that, assumptions on your part. We were always told that an ASSumption was the north end of a south bound horse.
All that said have a nice day and KMA in Macys window ,will give you an hour to draw a crowd.

I was guessing 8-10 hours but ganging them up sure would reduce the time. A shaper for max metal removing on rough stock is still a good choice for me.
