    1030 Tube/Pipe

    Thanks for the info. Machining a bar stock would be OK I suppose. Forging is a last resort due to time and cost. Any idea where I could find the bar stock?

    1030 Tube/Pipe

    Hi everyone, I am working on a weld procedure to weld A-516 Gr70 (P1 G2 ASTM material) to a forged 1030/1035 tube. 1030 and 1035 are not classified, so my procedure must use 1030 or 1035 to qualify it. My problem is I have been unable to find any 1030 or 1035 tube that is large enough. We...

    Two Questions Dealing with Top-Down Assemblies

    Alex, Thanks for the quick reply. Your described method seems the most logical to me. I have actually tried it but had problems with dimensioning with tolerances (see my second post above). This may be a drawing problem rather than modeling problem. Because, I was able to bring the entire...

    Two Questions Dealing with Top-Down Assemblies

    Shaggy, Thanks for the info. In all honesty, I guess I cannot complain about having to re-name a few files if it saves me all of the other time. I haven't had a chance to try it, but I think it has a find/replace function too, which could make it pretty quick. Anna, how did you get access to...

    Hydraulic Cylinder Codes

    This may seem like an odd question, but I have always operated under the assumption that hydraulic cylinders should be designed and manufacturered to ASME Section VIII code since I consider them to be pressure vessels. I have worked for a cylinder manufacturer and we desgined per VIII code, but...

    Two Questions Dealing with Top-Down Assemblies

    Thanks for the info guys. I am unable to sign up for the SW forum because I do not have a service agreement. I wish I did, but do not have access to it unfortunately. Any ideas from the folks here? Thanks!

    Two Questions Dealing with Top-Down Assemblies

    Thanks for the quick reply guys! Shaggy, thanks for the links to the SW site. I read some of Mauricio's posts that got me started, and those helped some. I will say though that they were over my head for the most part. Unfortunately, I do not have access to the SW forum to post. Drawoh's...

    Two Questions Dealing with Top-Down Assemblies

    Hello everyone, I am relatively new to SW and a complete newby when it comes to top-down assemblies. I have been reading up on them online and have come to the conclusion that my best bet is to create a layout drawing of my assembly (I can represent it in a single layout view in 2d. I can...

    Parameter Tolerances 2008

    Hello everyone, I am driving myself crazy trying to figure out how to assign tolerances in the parameter table. I have the dimension, name, etc, and I can tell Inventor how to display the part (min, max, middle of tolernace). However, I need to easily define tolerances (ie without right...

    Interesting Motor rebuild (maybe)

    Thanks for the information guys. I decided to order a gas shock to assist the door. After looking at all of the options, I finally decided that would be my cheapest and most reliable option. I will end up having to cut holes in 2 covers and build special brackets, but I think I can squeeze it...

    Interesting Motor rebuild (maybe)

    Hmm, thanks for the suggestions guys. I will see what it'll cost to re-wind it. I will also try the steel tube trick and see what it does. The biggest problem with going with a different motor/gearing/etc is that I will have to take a lot of time and some $$ to do. I have a new vehicle on...

    Interesting Motor rebuild (maybe)

    itsmoked and waross, Thank you for the information. A picture of the motor can attached. Unfortunatly, I cannot get a picture of the application right now as it is behind several covers and in a tight spot. The next time I take it all down to replace, I try to get some pics. Waross, I...

    Interesting Motor rebuild (maybe)

    Thanks for the information guys. Btrueblood, I did think about two motors and that probably would be easier than a spring/shock assit or any other changes. However, I am still leaning toward rebuilding the motor. Not because I do not believe you guys when you say it is difficult, but because...

    Interesting Motor rebuild (maybe)

    Roy, Thanks for the information. A linear actuator will not work unless I completely rebuild the hinges and surrounding structure, which just isn't feasible for this truck. I could use gas shocks to help it, but again, I would have to fabricate all new brackets, cut covers to make clearance...

    Interesting Motor rebuild (maybe)

    Hello everyone, I have a question that hopefully you guys can help me with. I am a mechanical engineer and like to dable in some electrical stuff, but am no good at it. Anyway, I need to re-build a small DC motor. Here is the scenerio: I have a vehicle modified for a wheelchair that uses a...
