New maincaps question.

[Mike Taylor 3601]

you want cap to fit tight enough that you have tap the cap down into register and you have to work it back out if using bolts,I pull them up near top of hole and push sideways to remove cap,I have brass hammer with plastic handle that I use to remove and install caps i use the plastic handle.
I measured some blocks here in shop they had .002-.005 interference fit on cap and block.
Do you have loose caps or installing new ones?
