(Sorry if this has been discussed but in my search I could not find a definitive answer.)
I seem to be out of LP4-4 rivets and swimming in LP4-3 of course. Currently I am assembling the wings and attaching the ribs. As you know most of the rivets used for this task are LP4-3 but LP4-4's are used where the Un-trimmed ribs attach to the main spar.
I have a supply of N-Cherry rivets for aircraft spruce. These BSP-44's have the same grip spec as the LP4-4's from Vans. I see the LP4-4's are rated similar to the BSP44's (200lbs shr, 325lbs tens). My question is can I substitute the BSP-44's for the LP4-4's.
One item I note in the difference is the LP's seem to have a zinc coating on the steel mandrel shaft but the Cherry N BSP's appear to have a bare steel mandrel.
Any insight would be appreaciated.
Thanks
