I just trace the gasket on a sheet of white paper, or ink the part and press it on the paper. scan it to a black and white .tif, load it into corel trace and use centerline trace..Then verify the actual size, and hole sizes, and send to the laser.. done... I've used this method to make all kinds of gaskets.

Bill,

Why waste the time copying it... I just throw it straight on the scanner bed.

ok how about something bigger than a scanner bed

You run into the same problem if it won't fit onto your tablet. If it's not much bigger than my scanner, then I'll take multiple scans and stitch. If it's a huge item, then we're in the domain of a laser scanner... haven't had one of those jobs yet.

I go with Dan's method. I have actually placed a transmission right on my scanner because the gasket wouldn't come off in one piece and that was the least hassle way to make a gasket.

I miss having access to a large scanner, we had a Vidar Truscan at my last job, it was great for doing large scans.

I put mine on the scanner also, 300dpi is perfect size, then just draw the required lines using the three point tool. The way that guy did it on Youtube would take way too long for me I'm afraid and nowhere near as accurate.

I tried that, but the jack slipped and I broke the glass..

the drawing table is large ---actual surface is the same as the laser 24x36
its quick and easy like this herron

I've done that too, but if it's a simple gasket (i.e. alpha 1 outdrive etc) it's just as quick to run a fine point sharpy around the edges,trace it 2bit and have corel centerline trace the line. No cleanup of the art, 'or' the scanner glass

That's (mostly) my process. I scan it in as a grayscale image, do an edge find, then "find outline". I try to remove any manual edge finding, tracing with pens, etc.
