Hello Group ,I am ready to drill the 5/16 holes in  my center spar and the wing spars on a 601XL .I have just bought a 5/16 reamer  and a 9/32 drill bit .I have received some good advise from Dave Clay as he has  recently completed this task . Any additional advise or tips from fellow scratch  builders that may help me on this task would be greatly appreciated .   Thanks

Wade-

     I didn't scratch build my  outboard HDS spars but had to rebuild 95% of the parts, so I guess I qualify as  an advisor. 

     1. Get yourself one of those  roller stands and level it with your drill press table. Then you can just slide  the spar from one hole to another.

     2. Use a "Clicker" center punch  to locate the holes in your layout. Steal some Ultra-Fine Sharpies from  work.

     3. Use a tailchuck center drill  for a lathe to start your holes. They have a huge shank and only 1/8" of actual  bit, so you get no creep. I got mine for $2.85 from J+L Industrial Supply.  (Less shipping, which quadrupled the final price). They're stock items if  there's an industrial machine tool outlet in your area. You're not going to find  them in Wal-Mart or even HF.

     Would you believe I saw a  half-dozen robins in the trees outside the building I work in freezing  their little tails off in single digit temperatures?! Their frequent flier miles  probably expired.

     Good building.

                                           do  not archive

Wade,



I used a laser level to set the dihedral of the outer spar to the center 

spar.  Fit your outer spar to the center spar and lay flat on your 

workbench.  Tape the laser level to the bottom of the center spar with the 

laser pointing toward the wing tip.  Measure the distance from the laser 

beam to the bottom of the outer spar where it meets the center spar and add 

this to the dimension you calculate at the tip.  6-W-4, lower right corner 

gives you all the measurements you need to calculate the rise for the 5.65 

deg angle.  A scale held at the end of the spar will allow you to set the 

angle within 1/2 mm.



Good luck,

Herb

Thanks to those that replied with suggestions to  this post. I may get enough nerve to try drilling these holes  today.

Wade-

     Put your mind at  ease- practice on scrap until you're comfortable with the  process.

                                     do not archive
