My winter Rolling Block Projet

[OlDeuce]

Well there wasn't anyone home when the fedex man came so I can't get mine until Monday.
I have lots of questions that I planned on the gun providing the answers.
Are the barrel threads metric?
Could an 8x58RD reamer be used to modify standard 8x57 dies.?
How difficult is it to modify the extractor when you go to a smaller rim size?

Oh No...............LoL You have to wait now Sorry

I haven't run across one with metric threads yet. The extractor takes some tig welding work to build it up to go to smaller calibers.

marlinman ...question....... do the set triggers work in these old frames that are made by Pedersoli or Uberti????? Ol Deuce

Haven't tried them myself, nor do I know what style Pedersoli uses to be able to guess. Some set triggers use a sear vs. the trigger to hammer connection, and those require an reworked hammer with a fly, plus the sear, plus the trigger group. If that's the case just putting the trigger plate in wouldn't finish the job.
I'm going to a friend's house this week to look at a trigger plate with DST in it. He wants to sell them, so I'll need to figure out what they are, and see if I can find a Pedersoli drawing to determine how theirs work if I buy them.

Looking at what I have ,my thought was to bore & tap 2 small holes for some set screws. one set screw would put upward pressure on the main spring,and
the other on the hammer spring!!! Just to ease the squeeze

So far my thoughts on the barrel lock is going to be sweet for a total tare down with only a screw driver !!!

Thanks Marlin man.
Ive been working on some dies this weekend. I'd like to shoot it as is but before I invest too much money I'll rebarrel. Right now I'm thinking 38-55 or 40-65. But that's down the road a piece. Planning on retiring early next year if possible.

Hmmm? The mainspring IS the hammer spring! So not sure why you'd use two screws for the same spring? And upward pressure on the mainspring would only increase hammer pressure and make the trigger pull even heavier.
The piano wire trigger spring swap is the easiest and quickest way to reduce trigger pull from 8-10 lbs. to around 2.5-3 lbs. If the mainspring is extremely heavy, reducing spring width on it will also help reduce trigger pull.

the main spring goes right to the hammer and right below the mainspring is a flat spring that connects just below the sear of the trigger !!! ???? Maybe
I'm looking upside down.........Hmmm I'll post ya some photos !!!! Krazy thing

[marlinman93]

Single trigger Rolling Blocks don't use a sear. The trigger directly contacts the notch in the hammer. There is a trigger return spring that rests on the trigger.
Here's a good view:

Got it ...Thanks .........How did the Dbl.set trigger look???? Ol Deuce

Well the FedEx truck has finally arrived.

These puppies are heavier then I had thought, my weighs in at 11.8 pounds.








Now to see if it is a shooter.

[Wolfer]

Picked mine up today also. It looks much better than I expected it to. I can't wait to make this thing go bang!

I believe the lower spring is what holds the trigger into the hammer when the block is open. You can't pull the trigger unless the block is fully closed.
Midway has a video on YouTube with a cutaway that really shows how they work.

I'm understanding that .....I guess I didn't say it right on the hammer spring !! Let me try it again... I'm thinking of removing most of the tension and coming back with a adjustment screw to bring the hammer spring back to what I think I need for proper tension with out going beyond the realm of safety Does that
make sense ?????? Ol Deuce

It does now. I'm kinda slow!

[sharps4590]

MOA, I'm surprised to read how heavy they are. Mine doesn't feel that heavy and it's just like yours, 'course I'm used to packing around Sharps, double rifles and the like and they're that heavy so maybe I'm numb or dumb.... Now I'll have to weigh it...lol!

Wolfer, the one I have was a hoot to play with. Got it going and now it's time to have some fun with it. God luck and enjoy!

For trigger return springs you can't beat these folks; http://www.rollingblockparts.com/swede.html
I put one of their springs in mine and it dropped it down to about 3lbs. Great for hunting.

Thx a bunch. I'll be checking them out for springs and other stuff you can be sure.

That should be a "lever" not a spring. The lever interacts with the block to prevent firing if the block isn't fully closed. Not a spring.
