  • Re: Yellow slide rules

    The Dremel paste I used is a redish brown color labeled Cat no.421.It's at least 12 years old.I have never used it till today and it literally made the edges nearly as polished as the faces.The heating technique,if done correctly,could put a nice finish on those edges in a couple seconds.The info on melting temps of the plastics is probably available

    Geoff The mill is made in China and is sold by many names.One that comes to mind is Grizzly.It cost me about $450 US several years ago.It's decent quality but not as nice as those of Sherline,and some others.Actually,I saw a router table accessory for the dremel that might be as good as,if not better than, the mill for making parts like these.

    Results were good! 3 down,2 to go.Guess which one is the original.

    Geoff Just got done polishing the edges.I'm very pleased with the results,nearly as polished as the faces.The mill leaves a pretty smooth finish so I went 400 grit,600 grit,1200 grit,10 micron paper,followed by the buffing wheel on the dremel with some sort of rouge that came with the dremel kit.The heating technique I have done on other projects

    Geoff That's some nice work for just using a dremel tool!I have three completed with the exception of the orange line,the spacers,and something I didn't realize:the edges need to be polished!How did you get the exposed edges polished?My thought will be a few grades of fine sandpaper for starters,followed by a polishing compound on the dremel

    Geoff Do the thin bearing surface shims that you added need to be clear?I have some white material available of the proper thickness. Paul

    Geoff Are the wider windows of the 4000/4400 also of thicker material by chance? I have three nearly complete for my 3000.So far so good.I had hoped to do all 5 in an assembly line fashion but my mill would only accomodate 3.I also have been mixing some colors to get the proper orange and have been consistently able to make clean lines on a scrap piece

    I don't own a 4400 but I saw some pics and it appeared the cursors were thicker on that as well.Maybe someone can verify this.

    I agree.I looked at mine with my face 6 inches from the glass, using a magnifying glass and it looked excellent.I am sure Geoff will second this for his experiments.Unless someone out there has super vision,we do have a winner.Now my next dilema is getting the wife to relieve me of some home improvement duties so I can get into the garage to work on
