Yes, that's very true. The bottom line is that as a machine-shop-only, you're creating ongoing value for someone else. Design and self manufacturing is not for everyone. Neither is being a job shop. Everyone has to find what they're good at.
The OP mentioned his own products. Pulling from Jay Pierson's videos, since he's also got products we all understand: he started making mountain bike parts on a mini mill in his dad's garage. He did job shop stuff too. Not sure where he was going to go. He eventually had to design his own hold down fixture for some work he was doing. That fixture is what took off.
His talent for designing things that fixed his own problems is the basis of his business.
Everything that is Haas Automation is only 40 years old. I first toured the factory in Oxnard 19 years ago. They used to offer the three-day control training for So Cal at the factory. They already had a million square feet and were pumping out 800ish machines a month, inside of 20 years. That all started in the family job shop with a Yuasa indexer and a hobby computer. I once had a brochure that was still branded as Haas Brothers. Wish I still had it because I didn't realize how short a time it was branded that way. If you want a laugh, look up the address on the bottom of the brochure and try to wrap your brain around going from that to a million square feet.

You have apparently never had to install, and true a Pierson Roto-Vise?! (I've had three of them not counting the first POS I sent back) His mounting design is terrible at best.
And I, as an experienced CNC machinist in every aspect from pushing buttons to owner, Including design and engineering, know why.
When I put two in a Brother pallet machine with 4ths on either side, I made my own adapters to proper tolerances, and ditched his, immediately.
Those two bolted straight on, truer than any of the other times I installed one on a haas rotary. His parts in the system are high quality. Tolerance on the mounting parts is dead nuts. They are great vises (for 1st OP, and some low tolerance 2nd OP). It is just a retarded mounting system, for all the wrong reasons. And then, he tried to tell me I was wrong about his "system". (knowing how long I have been doing this, comparatively to how long he has been at it). Justify his "system". And measure a vise body on his plate, and send me a video of the process to prove his findings. He was also sure to tell me how much his fancy-pants latest greatest whiz-bang digital Mitutoyo height gage cost, SMDH, LOL.
I'll put it this way: it is kind of like an adjust true chuck on a lathe (but not at the same time). Then he slipped up and told me he once had a guy from overseas that tried to install one an old beat up rotary that the centering spud wouldn't go in. At that point the light-bulb came on! Thats all I'm gonna say.
I actually like the guy. I'm not slamming him as a paerson. I'm sure he is a great dude. I just disagree with that stupid system 100%.
And the fact that he refused to listen when I tried to explain that the condition of other peoples tools is NOT his problem. Like I said, great stand-up guy.
I absolutely hated arguing with him. He is hard not to like, LOL. I don't mind spending my money on his stuff at all.
Great vise.Really great vise actually! Huge increse in throughput on the right parts. Just dont try to hold less than .005" on 2nd/3rd OP work. And once you pull pocketed soft jaws, toss em. They will never go back on the same. Stupid mounting. But, If I needed another, one I wouldn't hesitate to buy.
I made my adapters to .0003" under the rotary bore size. And concentricity is dead front/back. I bolted them up. And everything on the vise body to the machine was well under .004". Better than I could ever bump one in with his system in a haas. I almost sent him a video stating "I told you so", LOL. But I let it go.
Prolly seems like I'm arguing with you as well, HAHAHA. I'm not. Just sharing experiences.
