    Help with Butterfly Latch

    I work for a company that design mobile satellite positioners. We have a customer that is insisting we use a latch for their hardware cases that can be set in position during unpacking and stay in position (friction or detents). Typically we use latches that are spring loaded to hold the hooks...

    Congratulations spongebob, you must be at one of the few companies remaining that are burdened with overhead. I hope you have a monopoly.

    Disc brake

    Opened just fine with SW 09 vintage. I'll get it home and check it with their major competitor. It's configured for what I need.

    Disc brake

    STEP or IGES works. That's the brake that I'm using. Yeah, I found some IS PDF's on the Hayes site and some really good overhaul and service parts manuals on the SRAM site, but no caliper info. I'll swap a model/print of my adapter for the caliper model.

    Disc brake

    Anyone have a model or dimensions for a Avid or Hayes caliper? I'm trying to add disc brakes to frame that only has cantilever mounts.

    Heavier section for 29er wheels?

    Bottoming out the suspension would more likely cause the rim to flat-spot not taco. To taco a wheel the force would have to be applied normal to the rim x-section and not radially.

    Heavier section for 29er wheels?

    With the mtb industry moving toward 29ers I'd think that the rim mfgr would be optimizing the x-sections of 29er's for the higher moments that can be applied. Stan's website says their 29er rim has been optimized using FEA. http://www.notubes.com/rim_builder.php/cPath/680

    Fastener of Choice for Composites

    I'm delving into a new realm of mechanical joints and need help selecting a fastening system. Who makes a good fastener for joining carbon fiber laminates to steel or aluminum structures? I somewhat familiar with the Huck system, but would like other suggestions.

    Cross Section Help

    I know that you can create a section of one part in an assembly, but is there a way to omitt an component from an assembly cross section? I've been away from Pro/E for about 2 years and my skills are a little rusty.

    Thin shell assemblies, bonding

    From my limited experience using Cosmos with assy's I've not found an easy way around the split lines when doing shell meshes.

    natural frequency of panel

    You can add a point mass in Mechanica, or make a box that will have the same footprint as your motor and assign it the mass of the motor. Erik

    Projection Welding

    Unfortunately no. The plate is really a standard sprocket for a stamping supplier and the quantities that are required are too low to invest in new tooling. The spacers are going to be used as offsets for the sprocket. I don't want to get into tacking all the spacers on the sprocket and a...

    Headtube ID 1-1/8"

    I didn't know that this product was out there. I knew that you can buy reducers which is what I am trying to make. I can get the reducers made on a Mazak at work for nothing.
