Can anyone recommend a company that can supply Countersunk Rivets that meet ASTM A502 - Grade 1, 2, or 3? Thanks in Advance!!

Thanks for all your replies and I agree with all of them. I knew this was a long shot but just wanted to put it out there just in case someone had done this previously. Currently we do this process by machining and were just looking for ways to cut time without creating a hot work plate (for...

I am investigating a manufacturing process in our shop where we are cold forming (pressing) the countersink detail into the plate rather than machining it. The countersink is for a 3/4" bolt and a 3/4" plate. Problem is the plate is splitting to the end of the plate which is 1.625" from the...

I have a hydraulic device that operates at very low pressures. To date, it has been completely filled with oil and is then sealed (no hoses, lines, etc are present). Ambient temperature conditions are causing the oil to expand which increases the internal pressure and has caused the device to...

Thanks Everyone!!! Do you know of a good source for Bulk Modulus / Compressibility Factors and also Volumetric Coefficients of Expansions for fluids??

I am trying to calculate the pressure change due to temperature fluctuations of an incompressible fluid (Transmission Fluid) inside a closed reservoir tank. According to an equation I have found, h2 - h1 = c(T2-T1) + v(P2-P1), provides property changes of incompressible fluids where: h =...

During rivet installation, I will have a substantial amount of clearance on both sides. Any excess material on the tail end that protrudes will be ground flush with the edge. Once installed in its final resting place, clearance will be limited and that's the reason for choosing countersunk...

I am in need of some assistance on where to find a rivet tool, press, or hammer that is capable of finishing 1" solid steel countersunk head rivets. The tail will also be countersunk as I have no clearance for any protruding material on either side. These are 1" rivets with a finish length of...

I am inquiring into if any of you have ever cut holes into a piece of fiberglass cloth. I need an efficient way of doing so in a production environment prior to bonding the cloth with epoxy. I have inquired to our local Laser Cutting Shop to see if they can do so but I'm not confident this...

Thanks, definitely planning on going to a training class when we purchase the software.

I am pushing to have a few seats of Solidworks Simulation Professional purchased for my engineering group. I would like to hear your experience with the software. What problems have you run into? Would you reccomend it to a new user? I have used Solidworks for years so the user interface...

hydtools, Thanks for your reply. Current power unit configuration is 2HP @ 1 GPM rated for 3500psi. A cooler would definitely solve the problem but a cooler is just not an option in its enviroment. 68 grade was just something I could get my hands on quickly. I'm having a little trouble...

Thanks guys. I agree that I am asking alot of the pump and could be that I am just asking too much. I believe I will change the Top Limit Pressure to around 2500 psi and see how the system responds. To give you a little more background, the system is operating a 2" Bore Cylinder 4" in stroke...

Ok guys / gals, I am currently having problems with Hyd. Fluid Viscosities effecting gear pump performance. Background of System: Pump Charging Accumlator to 3000 psi with Pressure Switch in line to turn pump off. Accumlator Discharge every 36 seconds. Repeat Process. Background of...

Thanks. Sounds like a reasonable approach. I'll do the calcs and then do some actual testing once the prototype is complete. Thanks again!

Any Help you could provide with the following question would be greatly appreciated. Problem: I am trying to determine the velocity of a piston through a hydraulic cylinder. (Rod goes through the piston with a gap of known area to allow allow the fluid to flow from one side of the cylinder to...
