tumblers

[OptimaAndy]

I bought a TC powerrod for my Optima Elite and it is a little loose. How would i go about tighening up the tumblers. they can squeezer together a little tighter but unsure as to how to do it so that i don't ruin it.


thanks

i believe its just a flat spring in the forearm that puts pressure on the ramrod and holds it in place.

Do you mean the thimbles instead of tumblers? They are the ramrod guides on the underside of the barrel. If so there should be a small hole in the middle of the thimble which takes a very small hex screw that will tighten them.

nope, no screw. they are somehow slide into slot made into the barrel. they kinda pinch in the middle, which has a gap that could be squeezed together a little more but i am not sure as to how to do it without scaring it up.
I will try to post a pic.

lets see if this works

I don't have any experience with CVA guns was referring to TC thimbles. Doesn't look like anyway to tighten those from the pics unless like already mentioned with the tension spring.

Andy,

CVA uses spring steel ramrod guides (thimbles). Don't try to squeeze them or anything, otherwise they may come loose because you will change their configuration. Like FG said, there is a spring steel in the stock that keeps pressure on the ramrod. Try bending that up a little to add more pressure. You could also add something it the guides that would apply pressure or decrease the diameter of the guide. Some mole-skin (fleece) with an adhesive on one side might work to tightem up the inside of the guides and quiet things down as well.

Cut a 1/8th" wide strip of the "sticky-backed" velcro and cut to the thimbles length. Degrease the inside of the thimble with some alcohol and a Q-Tip. Insert the velcro (use the fuzzy half of the velcro) on the flat side of the inside of the thimbles. (towards, or on the barrel) See how that works for ya.

thanks for the tips guys. 8) 8)

no way of tightening that. CVA (bergara i should say) designed the thimbles like that to avoid drilling/welding stuff and creating pressure points. Your barrel lugs should be slotted and pinned as well if its like my Accura.

 

[OptimaAndy]

ummmm, what are barrel lugs???

 

[frontier gander]

barrel lugs are what your forearm screws onto.
