Hey All,
I was wondering if someone could help a newbie (me) decipher the instructions for Step #8 in the Van's Practice kit (not the toolbox).
The step reads:
To me, as a newbie, it seems like this paragraph has two different set of thoughts in it - one says it's too thin to countersink, the other says to countersink the spar. Maybe I'm reading too much into it? Probably way easier than I'm making it.
Thanks!
Casey
I was wondering if someone could help a newbie (me) decipher the instructions for Step #8 in the Van's Practice kit (not the toolbox).
The step reads:
Disassemble and debur all components. Dimple the remaining holes in the spar, skins and ribs. Dimpling the spar is a special case. It is 0.040" think - a bit thick to dimple well and a bit thin to machine countersink safely. So, we combine methods by dimpling first, then enlarging the dimple with a hand deburring tool. This is done by eye and tested by dropping a rivet in the hole to determine fit. Machine countersink the spar and trailing edge wedge with the microstop countersinking tool.
