  1. AMK 1/48 F-14!!!

    I once had some gears cut via wire EDM because the proper cutter was 22 weeks out. I took the job to a guy that is about the best I've ever seen with EDM processes. He told me what he had to have, and I got him the stock he needed. Tom cut the gears in about ten hours at a cutting speed of .040" a minute, and brought them down to me to cut the bores and key ways. (I usually did the bore first, but was too pressed for time and his machine was empty). The finish was barely acceptable, and felt like 400 grit sand paper. I knew they were very accurate, but also knew they'd wear in and become loose. Tom cut them within a thousandth of an inch, and the only way better would have been to grind them. Too late! So I cut some more steel, and went thru the same process, but leaving an extra .003" all the way around. Then Tom went back in and cut the remaining .003" and a very slow rate. Gears looked satin finished, but were actually very smooth. Tom explained that there was a spark that came off the wire or slug that would also add a very fine pitting to the surface. The three thousandth cut at a very slow rate made up for about 75% of the pitting. The cutting device (wire or slug) actually burns it's way thru the metal, and there's always a little bit of a spark going out from it. Different metals require different current to be cut. I can't tell you all that much about the setup as I was just the guy who processed it thru there. Yet I did it seven days a week. I'd say the best micro you can get is about a ten or twelve, while a ground finish will come in anywhere from four to a ten. To get that mirror finish some of us want, your looking at months of hand lapping and a lot of diamond dust. gary

    there's alittle more to it than an EDM machine process. You'll need what is commonly called out as a "sinker". This machine does not use the common seen .010" or .012" brass wire to cut the metal. A sinker uses either a male version of the cutting area done in graphite or copper inert tungsten. Either way you first machine a male image of the part you plan to make. Cutting process is very slow. When you finally reach the finished depth, but short about .002", to go back in there with a new slug that is very finely finished to clean everything up a little bit and make all the corners and angles near perfect. Making the slug can be easy, or can be horrible. You drop something on it, and you start all over. The copper / tungsten piece is better, but also extremely expensive. A piece of Copper/tungsten the size of the kit parts will cost as much as a new car! gary

    Please note that I'm unaware of what planet some of you guys reside on. I pre-ordered two kits from Victory models a few months back, and those people have yet to take one dime out of my bank account. If you paid in advance when AMK said you'd be billed when the kits arrive, then I got a bridge to sell you. gary

  7. What other hobbies do you guys and gals have?

    want to find out how good a bass player you are? Then pay a visit to the International Bassist Society convention. I did once, and then went to see the concert they put on. It was dedicated to Scott LaFaro (possibly the finest bassist to ever play). I was just stunned everytime zi saw somebody playing. Didn't matter is it was a regular electric or a stick. The best were the acoustic uprights with cat gut strings and un-mic'd. Only the masters attempted this combo. gary

    you know by now that cutting a mold as complex as the Tomcat, and getting it right is a serious task. EDM processes make it easier, but will flat drive toy insane! Then there's the micro finish issue. Once you get there; you get to start all over again to get the final micro. (what are you looking at? A four or five?). This is not an over night process, and one should be thinking about .015" a minute (or maybe even .008" per minute). After that, you touch it up by hand. been there and done that gary

    I'd rather see somebody take their time and get it right from the start. Plus the last time I looked, it's still November, and not December. Well maybe some folks are using a different calendar that others. gary
  12. 'New' 1/72 Academy F-100D... which plastic in the box?

    decals are the same as in the Italeri kit. Nice decals from Cartograph. gary

  14. Tamiya Release Rumors?

    think they have you on IGNOR glt
  15. Tamiya Release Rumors?

    I own a couple Trumpeter A37's. Actually one of their better jets, but also not quite perfect. Their F100's leave a lot to be desired. The F106 wasn't bad, and I'll probably build it OOB. Hasegawa does the F104's in 1/48th. They're OK, but always leaving you wanting more. Still like them. Pretty much the same with F105's! Love to see ZM or AMK tackle the F100d or F105 series. glt
