I am trying to output the data from graph tool in mechanism. I can output the text file (.grt file extension), but when I chose to save the excel file it acts like it saved the file, but no file is generated. It allows me to choose a file location, and no matter how I search I can not find the...
I am having a issue with comparing data sets from two assemblies via mechanism. I built the first assembly and ran the dynamic analysis and exported the data via text file to excel. I did a file copy to get a second assembly and varied one of the parts in the assembly. I ran the dynamic...
I have a HK series drawn cup needle bearing with a steel cage and outer shell. In some cases the cage is coming in contact with the shaft (acting as the inner race). By looking at the bearing construction I can not see how the cage can touch the race, while the rollers are in position. Has...
We have had some prototype parts made from Si3N4 for testing. The testing went well, but we now need a manufacturer to make 500 to 1000 parts. It is a cylinder .500" O.D. with a 0.25" ID and is .25" wide. Who are some of the manufacturing companies that I can contact for a quote? Thanks for...
I need to get parts Salt Bath Nitrided and am looking for companies to do it in the USA. Are there any companies that you would recommend or not recommend using? The parts are made from 4140 / 4142 PHT with an Rc = 30.
Thanks for the help.

I am trying to replace a needle roller bearing (no dedicated inner and outer race per say, uses pin and outer housing for races) with a bushing. At this point I need to find a material I can machine myself to make the bushing. I have looked at Glacier Garlock LB9-machined bronze as a possible...
I am in the process of designing a part made form M-2 tool steel, which will need to be welded. I will have two tubes 0.600" in diameter with 0.050" wall thickness. The tubes will be "butted" together with a small overlap on the I.D. for centering then welded. The welding will be done pre...
I am trying to find a general torque "rule of thumb" spec for the following fastener sizes:
6-32
6-40
8-32
8-36
10-24
10-32
The fasteners are holding cover plates and are being threaded into Aluminum, due to the nature of the application the only stress is what is induced by the applied bolt...
I have a tube with a 0.300" hole through the center. I need a compound that will allow a user to assemble an insert into the tube via a slip fit, but when cured will not come apart. I have tired various loctite compounds (272, sleeve retian compound), but the inserts come loose during usage...
I am designing a part that is a long slender rod that must be very stiff. Most of the steels I have looked at have a modulus of elasticity that is very similar. Is there an alloy that has a very high modulus of elasticity (maybe a metal matrix)? I am not concerned at this point about buckling...
