Big Steve Posted September 21, 2009 Share Posted September 21, 2009 I thought some of you could use this quickie drill jig idea. I took a chunk of aluminum and squared off the face. Then drilled a hole through it the size of my drill I was going to use. You mate it flush up against the surface you are going to drill and you get a nice straite hole. I used it to pre drill my spar pilot holes. Yes I am back Jon sent me my password. Thanks Jon.

Edge 513 Posted September 21, 2009 Share Posted September 21, 2009 Great youre back! Was wondering about you. I guess a guy could do the same thing with a block of wood. Wouldnt be so robust, but not many have 1-1/2" thick chunks of aluminum sitting around. Nice construction tip. Quote Self confessed Wingnut. Now think about it...wouldn't you rather LIVE your life, rather than watch someone else's, on Reality T.V.? Get up off that couch!!! =) Progress; Fuselage on all three, with outside and inside nearly complete. 8 inch extended nose. FHC done. Canard finished. ERacer wings done with blended winglets. IO540 starting rebuild. Mounting Spar. Starting strake ribs. Link to comment Share on other sites More sharing options...
rickh Posted September 23, 2009 Share Posted September 23, 2009 Along these lines, this is the jig I used to drill the holes for the elevator tube. Quick/dirty on the table saw, blade tilted to 45*, run the block through on both edges/sides ("V" is now perfectly centered). Drill the pilot/guide hole in the jig on the drill press. "V" up, hand rotate the drill bit till the bit touches both edges of the "V", now drill away. Rick Quote Rick Hall; MK-IV plans #1477; cozy.zggtr.org Build status: 1-7, bits of 8-9, 10, 14 done!

Big Steve Posted September 23, 2009 Author Share Posted September 23, 2009 That milling machine a lathe and a really nice little mig welder are what is paying for this little airplane project. Using them on my plane is just gravy.
