    Questions regarding drilling small holes, and runout.

    I missed carbide drills. I suppose if you looked at engagement slow motion you might see one drill flute in gage before the other thus causing off set twist and fracture if metal is soft it might not matter as the flute would begin cutting. I’ve seen the vibration in high speed drills so center...

    Questions regarding drilling small holes, and runout.

    I always use a center drill carefully just touch the punch mark you can move it slightly then lightly center drill down to the thicker shank spot. This should give a pretty good starting point . If the drill is very small it still can bend a little as it begins the cut . If you must have a very...

    Fusion360 CAM Tips and Tricks

    Ironically my other son has my old computer that has an operating SW program on it. I did a lot of modeling on it . Once I told other son where to start he has began using it more . Unfortunately he is now 1400 miles away . I should have taken that computer instead of this one I guess but this...

    The SW version is supposed to be a full seat with analysis. However my late son may have deleted some of it as he did not realy know how to use it. I used at his home briefly and it seemed ok then I just never got to really get into it . I can’t even open some of the files he created. In...

    Fusion360 CAM Tips and Tricks

    Well my initial call to fusion was a total bust. I explained I have enough experience in solid modeling to probably pick up fusion pretty easily , however the contact just talked in circles I explained I’m not a business and it will be used for home and hobby stuff. Should we decide to go into...

    No, I have not tried as suggested. I’m completely fed up with SW . It did irk on the current computer. I do have a good internet connection. I YHINK the fusion single non business user is the way to go. We only build big Rc airplanes and details for them ultimately we would like to resin print...

    Oh my gosh I can’t wait to view this. I may have to have my son help me as I have such limited vision it’s hard for me to even see the key board Jensen the spelling mistake beyond what spell check does. I can’t really be critical after all it is scale . As in our big scale Rc planes some...

    (CAD) 28 Cyl P&W R-4360

    I may have gone a bit over board here what I was referring to was the 5360 used two spark plugs per cylinder with a 5” bore give or take it’s probably necessary to build a good flame front but 2 plugs per cylinder on a 2” bore would be very difficult and not really necessary other than scale...
