    Metallurgy services for steel analysis?

    Can anyone recommend a metallurgy service that can do an analysis on a steel alloy? I'm welding to an automotive steel forging, and I would just like to know the carbon content to have an idea of how I should weld it. The testing can be destructive, as I have a small (1x1x2") part of the...

    Best bang for the buck TIG welder

    I have a Diversion 165 that is just fantastic--welds great and ready to go for about 1300 bucks. Well, add 100$ for the cable and outlet boxes for a 30 foot dryer extension cord.

    Flexible polyurethane adhesive

    I'm looking for a polyurethane adhesive to bond a hard (75D) urethane casting to aluminum, but it needs to be pretty flexible (~60A). It will in fact be cycling in compression and tension constantly--it's for a automotive suspension bushing. So an adhesive thats designed for constant flexing...

    "Selecting" and flattening intersecting faces?

    Limey--fantastic! I had tried intersection curve before and had gotten an error, I don't even remember what it was. Then I just ignored the function entirely. Tried it again and sure enough, it works fine. I've gotten the cut-extrudes to work too it appears...if all else goes well, I should...

    "Selecting" and flattening intersecting faces?

    I've been trying the last hour or so with a sheet metal model, and have been running into different problems. I can sketch the contour with surface-splines, but cutting it is giving me problems. There's no way I know of the make a cut-extrude tangent over the whole surface (as in, setting the...

    "Selecting" and flattening intersecting faces?

    And for that matter, even with a hand-drawn spline sketch, how would I "unwrap" it from the model? I can't think of a way to do it in the part or in a drawing...

    "Selecting" and flattening intersecting faces?

    Thanks Tick. That's what I figured would be the only way to do it. Unfortunately, SW doesn't want to convert the intersections between the pipes, either in the assembly or when editing the part in context. It looks like I'll have to use freehand surface-splines to draw the outline, and then...

    "Selecting" and flattening intersecting faces?

    I have a model with intersecting pipes, and I'm having some trouble making a useful drawing so the pieces can be made. This is what I have: What I'd like to do is "select" the visible part of the cylindrical face, with the outlines being the lines of intersection with the neighboring parts...
