Yes, drilling out the olympic rivet will make the hole size bigger but they were drilled out larger than what the solid rivets were from the factory, because the Olympic are made 3/16 not smaller. So replacing them with 3/16 solid rivets will work.. Yes some will be a tad undersized but will fill that void or hole when you buck them in place because they expand into the hole size and mushroom on the back side. The VTS rivets are slightly softer than the Blazer rivets (no longer available) and will work great for your repair.
Thank you Vinstream for all your help.
I really want to do the job right and fix the structural integrity of the outer shell.
I'm still a bit confused though.
I assumed that the Olympic rivets are probably 5/32 size, not 3/16?
So you think the olympic rivets are 3/16, not 5/32?
I haven't drilled any of them out yet, but was thinking to use the 5/32 (#21), if in fact they are 5/32 drill bit to drill them out, which I thought would enlarge the holes as you said, but then buck riveting the larger 3/16 soft brazier aluminum rivets? Would it be better to drill them out with a 3/16 drill bit if I am to use 3/16 size rivets instead?
It seems VTS does not carry any buck rivets larger than 5/32 size.
But I found this link which has the soft modified brazier rivets for size 3/16:
Another question, I'm sorry I'm asking so much as I have 0 experience doing this....
When I buck rivet, should I dab some vulkem in the given hole as well as the buck rivet before bucking? Was a bit confused as to whether or not I should just put vulkem on the the back ends after bucking or to apply vulkem to the solid rivets before I proceed to buck?
