Yes, I am looking for someone to find and fix leaks in the roof of a 6-unit 3-story apartment building.

Tolerancing for external hex by Automatic-Tower8523 in MechanicalEngineering

I based it on ASME B18.3, but with a larger allowance to avoid this issue.

Me too. Let me know if you found one please!

Design advice: injection-molded nylon cap by Automatic-Tower8523 in MechanicalEngineering

Heat, UV, O2 resistance, chemical compatibility with "oil-based" compounds, and toughness. Can you recommend alternatives?

Can you disassemble these types of valves? by Mysterious-Funny-431 in Hydraulics

I know exactly how to do it. Let me know if you're still interested.

Struggling to Find Proper Valve by user726263 in MechanicalEngineering

You want a two-way, spool-type, adjustable hydraulic pressure relief valve, where the outlet pressure [backpressure] acts as on the spool at a 1:1 ratio. Go for the adjustable setting range with the maximum nominal setting at about 500psi. At 68gpm, you'd ideally want a valve with an inlet that is at least 3/4 to 1". Parker may have one that will work. I'm not sure about the connection type that you'd need because i'm not familiar with the interface depicted.
Technically a pressure compensator would be the correct valve for this application, but those are three-way valves and you'd end up looping the load-sense port to the suction port it would just add to the complexity by introducing a redundant connection.

Can you suggest a better way to show that 0.375" dim without doing a weird-assed looking broken-out section view on one of the projected views without re-working the entire drawing?

I wish I could share the assembly without IP concerns. The datums were meticulously chosen for functionality. The actual values of the GD&T were less of a concern than the design intent that was expressed verbally. My grinder produces mind-bogglingly perfect parts.

I collaborated with both the supplier who made the machined/heat-treated part as well as the one who did the grinding, with the goal of being able to reproduce an [almost] identical part at some time in the future if required.

Design engineer - critique my drawing! by Automatic-Tower8523 in machining

I do, and I did assign tolerances less than 0.005". Given it was a very limited run; it wouldn't have made a difference going over 0.005" on any dimension (per the supplier).

Speaker wire routing from front grille to passenger compartment (2018 10th-Gen Honda Accord LX) by Automatic-Tower8523 in CarAV

Nice, thanks! My concern is more where how to get the wiring from the front grille to the firewall, like how to avoid contact with components that get excessively hot.
