Eltron, A bag of cookies and as many stars as I can give to you! Awesome Awesome Awesome Awesome!!! Great Model. that one will be saved for good! My whole mechanical branch here is in awe!

Hello, I am attempting to locate a solid model of a human hand so that I can accurately assess whether or not a hand will be able to fit into an assembly to tighten or loosen another part. can anyone direct me to a location where I may find one? Preferably free? Thanks in advance. Adam

this connection is of the higher pre-load variety. one part of the joint will be painted to maintain low visibility - the anode alloy. I have found in MIL-STD-889B Notice 3 that Nickel-Copper and Nickel-Cobalt alloys are incompatible in a seawater environment anyhow. I'm going to have to look...

some references that I have read have suggested that you need a greater than .15V difference in potential before you start to see galvanic problems... I have pretty much come to the same conclusion as you - the two metals, although different, are very close on the galvanic series and thus...

I have been asked to review the corrosion potential of a bolted joint. The fastener material is MP35N. This fastener is being used to bolt together two pieces of Monel K-500. The environment will be in seawater and the flow rates around the fastener head are likely to be very very low if any at...

I consider myself to be an intermediate user of SW. I taught myself to use it and have been using it professionally for about 2 years now. I just don't have that much experience with surfaces... Thanks for the help.

It's perhaps not the most elegant solution, but I offset the spline and just revolved the contour as solid in the first place. Thanks for the help! Adam

my fundamental problem is my lack of experience with SW in general and with splines in particular.

ok, thanks, ill give it a looksy...

what offset would you be refering to?

neglected to mention it's SW07.

I have created a spline and revolved it around an axis to create a "cup like surface". Im trying to thicken it to create a solid and i get a rebuild error "Face which failed check". Any help on this one? Thanks

HA, i didnt even look at the reference for the equation but you sure are right, that is one heck of an obscure reference. I challenge someone to get a hold of it haha. I probably wont be using the second equation as it is less conservative and it appears that the use of the stress area formula...

Ok, Thanks for clearing that up. I appreciate the help. Adam

From "An Introduction to the Design and Behavior of Bolted Joints (Mechanical Engineering (Marcell Dekker))" There are multiple formulas used for stress area because each one has a different factor of safety- one is more conservative than the other. I found it this morning :o) Oh and also...
