Boy, but I hate poor engineering!

You "sound" real, good. And the worst is there are some dealers who think they know much more than engineers and they force the owner of manufacturing company what/how to do - the owner listens to these dealers because them these dealers are the buyers and products are usually technically problematic because of the requests of these "wise" people. If there are someones to be accused due to technical problems, they are the dealers and owners of manufacturing companies.

You an me both...

Get this.. that reminded me of a very specific incedent that happened a few years ago. We needed a heavy circular rotating platform fabbed ( 7/8 steel plate ). This thing had brackets on it to bolt it to a frame. We had an excelent shop drawing.. very clear.. all measured.. scaled perfectly.. etc. spec sheet included. Sent it to an outside machine shop as ous was not setup to handle that .. and it came back.. looked great.. when the crew went to install it.. all the brackets were welded on 180" out.. making the bolt holes blind.. in other words.. the brackets only fit in place after the bolt was in place.. yet the bolt had to go thru the bracket.. etc.

Hard to describe here.. but the machine shop merely attatched the bracket, looking at the the lines and angles of the bracket to the plate/... without respect to the brackets being on completely backwards.. and being unuseable..

Caused a big ruckus.. was a few thousand dollars worth of work.. and they said the plans were flawed. We called in an outside machinest.. handed him the paperwork and asked him to look at the plan only and tell us where the bolts went.. in about 10 seconds he indicated the correct way ( opposite of what the machine shop did ).. they got mad.. we got mad.. boss said he was only paying half.. they counter-offered this and that. I don't know if we ended up paying full or not.. but in the end.. our shop had to cut the brackets off and re-weld them on... and we never used that other shop again.

the kicker was it was nice clean plans.. ... Even I could read them.. and I'm not a ME... ( CE technically.. though I spend more hours per week doing sound engineering.. etc. pays better to... go figure..)

As a "joke" we have put MIL-SPEC MITTP (Make It To The Print) on drawings before.

Nomad; you come just in time. There's another thread involving mower blades that could use the new one you designed. Good chance for you to get your product on the market.

Which thread? That "high-lift?" thread? This thread shows that those companies like Landpride, Craftsman, etc have changed their standarts from "high-lift" to "medium-lift" and this shows I had been right about that such designs can NOT be made - You, Egon, you are an engineer and you have not understood yet what I had educated someones here. You are missing the points. Have fun.

You got it right Soundguy!
And there is always the "can't you shave more off the manufacturing cost". Use a grade 5 bolt here instead of an 8 and save $20,000 in the course of a year, It will make it thru the warranty period ok. Engineering today is more about making the lowest cost product that will do the job, than about servicing convenience or quality that exceeds the minimum design specs.

I am not an engineer Nomad.
