My Epson Action Laser is on its fourth ream of paper and the drum unit is shot. A new replacement (my only option) costs from $180 to $240 depending on who I call. It's warranted for 30,000 copies or 18 months. The printer is almost four years old. I called Espon America customer support and suggested a drum unit should last for more than 2,000 copies no matter how old it is. I was told that the drum is made of organic material and is only good for 18 months OR 30,000 copies. The lady told me the drum material is like tires, whether you drive on them or not they still have a life cycle. What would anyone do if they bought a set of 60,000 mile tires and after 4,000 miles the rubber fell off, regardless of age? Assume of course they are properly maintained, driven once in a while, and kept in a heated garage when not in use. Epson stood by their policy. There was no acknowledgment of a faulty product, no offer of a discounted replacement drum. In fact I was told I was lucky to get four years out of the thing, even though the power was off the majority of the time. So, beware of Epson products. Think before you buy. I am cutting my losses and have already bought a bright shiny new Hewlett Packard. I will NEVER BUY ESPON again!!!! P.S. Espon reps if you're out there - As CAD Manager for an Engineering department, I'm responsible for speccing out engineering computer tools. Guess who's not on my short list...

I don't care what the title is, just as long as > I get paid! I'd be happy being called dumb-shit if it paid more than > $40K, I've been called that for much less. here's my two cents. . . As you can see from the signature my title is "technician" SOMETIMES(not all the time) I get offended if I'm called a drafter or draftsmen. In my opinion, you're called what you do. I don't mind being called a CAD operator. And that's funny because A drafter most likely has more experience the a CAD operator. I have over 13 years experience drafting, and 6 years CAD. I'll do manual drafting once in a while ( 1 or 2 days a month). Most of my time is spent supporting our 12 AutoCAD seats, 2 or 3 days a week of CAD work, and some Administrative duities. I get paid more the $40k, and I would not like to be called a dumb-shit. Money isn't every thing. I like what I do, and I like helping others. -- Mr. Desi Moreno desim@mid.org Modesto Irrigation District Electrical Engineering Technician http://www.invsn.com/desmos/autolisp.htmReturn to Top
I have read that there is an advantage to ahving graphite vs. steel shafts. Anyone care to ellaborate why this is. I assume steel is stiffer. Isn't this better for a fairly fast swing?Return to Top

Isn't this better for a fairly fast swing? I'm no expert on this but I think that the advantage of using "graphite" shafts (really composite shafts) these days is that you can have a whole lot more control over the stiffness characteristics of the shaft. Ten years ago, graphite shafts were always the "whippy" type and were made for people with slow swings so they could increase club head speed. That is no longer true with modern graphite shafts.Return to Top

There are many methods you could use. The choice depends upon the exact geometry you wish to inspect, what surface area, the speed required, the accuracy required, safety considerations, and how much money you have got. For example, positron anihilation spectroscopy is wonderful - if you can get the kit and don't mind lots of positrons flying around. Tapping, sounding, whatever you want to call it is cheap, easy, and tests the whole of a specimen at once. Tools are available if you dont trust your ears, or need to validate your results (this technique is widely used on airframes and aero engines). But is not suitable for all components. The most common method must be fluorescant penetrant inspection. Are plenty of inspection sites on the web, and you might also look at news:sci.techniques.testing.nondestructive Hope this is of help, Steve FoisterReturn to Top
