So two different young engineers and two situations that have my blood pressure up.
These two guys work for a company that I’ve done work for years.
----------------------------------------------
Engineer #1
Quote #1
Sends me an assembly to quote, one part is made from 3 pieces, but can be made from one piece. So I point this out to him, and send him a revised design so he understands. Agrees reluctantly it’s better. Also have to tell him there isn’t enough room to get a 1/4NPT thread in the sidewall, it needs to be 1/8NPT
Same quote has another 2 parts, a shaft and a disk. It’s a historical design that was a poor design from the beginning. The original designer had the design sealed with RTV on a thread, and on the face of a Nut. I changed the design to add an o-ring. None of my parts have ever leaked after the change. This young engineer doesn’t know about this change. He should but doesn’t. So I explain to him it should be changed, and even offer to make the change for him gratis.
Last part of the quote is assembly, which includes shaft seals. His assembly drawing shows seals as a blob, doesn’t show in the drawing the correct orientation. So I point out to him without specific instructions there’s a 50% chance a vendor would get the orientation wrong (not me I’ve been installing them correctly in a similar unit for years) and the vendor has to make a tool to install the seal without tearing up the rubber on the od of the seal.
Told him if gets the parts delivered assembled there’s no way he can verify the seals are aligned correctly or not damaged on installation. Short of doing a leak test.
So I spend a lot of time helping this engineer. I’m told a Chinese vendor quoted $400. So I looked at the numbers, and give a quote of $425, assuming a labor rate at $90/hour
Get an e-mail saying I have been approved for 5 assemblies at $425ea, and should expect a PO shortly.
--------------------------------------------------------------------------------------
So Engineer #2
Sends me a part to quote 16” dia disk with 10 pockets, pockets both sides are .300 deep, with lots of sloping surfaces, and
every corner has a .040 radius. And on one edge of the pocket there’s a tongue that sticks out that .600” ling and .04 thick. No material speciified
So I call him up and want to talk generally about this part, the purpose of the tongue, does he realise not easy to machine, and likely not durable either.
So he says he’s had it quoted in China, $510 landed to his door step. So I ask what material did they quote, he said they recomened Bakelite. I’m driving while talking to him, and nearly drive off the road.
“Do you know what Bakelite is?”
“No”
So proceed to tell him the joys of machining Bakelite and that it’s really unsuitable for what he wants to do.
We talk material, I asked did he consider 6061, no he said it might be too heavy, check in CAD, it's 13.2#. Customer says that's ok not to heavy.
So when I get home I modify his design to make the Tongue part removeable, so if they get damaged, remove 2 fasteners, and put a new one in. Send him a picture which he appreciates, and a quote. Which he says is too high.
So I said I assume your going with the Chinese vendor, doesn’t say anything. Then I said I assume your going to make that tongue removeable as I showed you, so your getting a better part and in Aluminum, and somebody else is getting the work?. Doesn’t say anything
No good deed goes unpunished.
---------------------------------------------------------------------------
Right after I send a quote to Engineer #2 and his rejection, I get an e-mail from Engineer #1 saying the 5 assemblies have been awarded to another (Chinese) vendor.
I HIT THE F’ING ROOF.
The e-mail also says he didn’t quite understand what changes needed to be done to the shaft to add the o-ring and would confirm with me the what was actually required. (THIS AFTER SENDING THE WORK ELSEWHERE!!)
So what to do?
I’m thinking, road, engineer, bus.
So write an e-mail to the boss.(cc’ing the engineer and buyer) The whole sorry saga. About the different stages I had to advise him on the design, the changes he should make based on the experience I had making similar parts for the company for years.
And specifically pointed out a couple of areas that if I hadn’t ventured some advice the parts would be substandard, and issues in relation to the seals
E-mail started off red hot, took a few re-writes before it was relatively calm and professional.
So a few hours later talked to the boss, he apologized, said Engineer 1 still had a lot to learn, and sorry for indicating you’ll get the work, and have it awarded somewhere else, wouldn’t happen again etc etc.
I'll find out thru the grapevine if he got a reaming or not. Hopefully he did.

Get this e-mail from Engineer #1
Hi xxxxx,
I realize now I messed up in my actions. Especially shouldn't promise we'd source an order with you, only to go elsewhere. Especially after you did extra work in the geometry and development that leads to a much better final result.
This is something I'm going to need to improve upon with myself and try to prevent from happening in the future.
Best Regards,
Xxxxxx
I e-mailed back
xxxxxx,
Thank you for getting back to me. It's all a learning experience.
Don't hesitate if you need any help in the future
Xxxxx xxxx
I think the chance of either engineer getting any help down the road is zero to none.
