72 OT cyl.,timing & drag ????

[Slamfire]

 Yep!!!  need more info. From the drag marks on my cyl. the bolt seems to be poping up to soon and leaves long drag marks on the cyl. I have polished the bolt after marking it with white ink and replacing the cyl.,rotating it ,,take it apart do it all over again until polished & even across the bolt. What do i need to do to retard the timeing of when the bolt pops up,,,,am i making sense  as to what i think  is the cause of the draging??

Ifnthe bolt is popping up too soon it probably has to do with how it's fit to the hammers cam. The hammers cam works the bolt.
The popping up too soon would be the bolts leg coming off the cam toosoon.
Try spreading the legs apart a little to make the one leg rub the frame and the other rub the hammer surface a little.The bolt may just be able to get too far from the hammer and it's cam soit can't stay close enough to the hammers cam.
Yer cam may not be proper also. You should open the bottom of the gun by taking off the backstrap and then the trigger guard and working the action (without the mainspring in it of course). You will see how it works and look real close to how the bolt legs are.
If the bolt legs ride the frame on one side and the hammer surface on the other and the hammer cam is good and not lettin the bolt leg slip off early then the one bolt leg is too short and you'd need it fixed or replaced. Naturally you would have to remove the hammer to study it's cam. Look at the wear/rub marks from the bolt leg and you can see if the bolt leg slips off the cam early.
Ifin you get stumped then....send the gun to Raven or Hoof Hearted or anyone you know that works on them or is an atual gunsmith.(ask them first about wantin to do the job of course) and they will spiff it up pronto and A-1 ready to go.
Ifin you live in Ohio and are close to west central part just stop over my place and I'll fix it fer free. I've got spare parts I believe. I'd have to go down the hill to the shop area in the garage/barn and check.

Hey, rifle,,yes sir i'v been doing all that you suggested,this 72's just a couple mts. old and it has been a kit from the get-go. None the less it just shoots to good ,and fits me fine i'm not about to bail out on her,,( or it ) . I'm not sure what ya'll call heavy cyl., drag ,,,but if i hadn't stopped the drag on mine ,,i'd be look'n at a 2pc cyl.,  I polished the bolt w/ a very slight drop on the off side ,polished the hand,smoothed up thr ends. Then looked at the hammer cam?? The bolt arm shows a slight wear (bevel) on the cam side also it looks like the trigger has been sliding over and hit'n the bole leg right at the cam. I dressed the very cornor of the trigger ( it did make asmall notch on the cam ),I think i have it figured out(?) from what i'v read on here.  Taylo's out ,,,,will   call whwn shipment comes in.....  Holler back, thanks rifle.

SlamFire, that was a good one....two piece cylinder. ha ha ha  Got me laughin.
Yer gonna have that "72" spiffed up pretty well with all the attention yer givin it.
I'm not sure what you mean......slight drop to the "off side" of the bolt?
You mean the first side to enter the cylinder notch?
With  the bolt head not draggin anymore that might not be needed(slight drop). Usually the bolt head is flat across the top since the Colts have the "ramp/lead in" to insure the first side of the bolt head entering the notch,and the side that hits steel notch edge first, is low enough in the notch to stop the cylinder. Sometimes the "off side"(first side to enter the notch) is made to be higher than the other side(like a Remington with no lead-in)to insure even more the bolt head is low in the notch when it gets to the notch edge it wacks into to stop the cylinder.
If you have that side of the bolt head at a slight drop(and I'm readin you right) then it would handicap it doin it's main function...stopping the cylinder. Less contact with the off side stopping side of the notch.
If you can you might want to change the top of the bolt head to be even with the other side or.....have a slight rise to the off side. Improve it's stoppin powder.
You know...yer right about the "kit gun" syndrom to some of the mass produced guns. Some come out of the box perfect and others......get people to learnin to be a "Kitchen Table Gunsmith". Kitchen Table Gunsmith......the most fabled and honorable pre-fession in the world. ha ha ha  Yer past Kithen Table Gunsnithin class 101 and are goin into "Advanced Kithen Table Gunsmithin".
Just by havin the guts to get inside and start improving things sets you above the average and lookin down from the mountain top.

Have you corrected the Arbor/Barrel fit yet???  The absolute first thing you should do with an Open Top.

There can be a  problem from qualitycontrol/design defect where the notch on the hammer fer the trigger is cut too close to the hammer cam.
Sometimes a longer bolt leg and grinding/diamond file the side of the cam to "move it over" is the only way to keep the bolt leg from getting influenced by that "too deep" hammer notch fer the trigger. You know....move the cam over to leave something fer the bolt too ride on the flat of the hammer so it stays on the cam  long enough and doesn't make a gouge and an easy access to slip off the cam too soon.
If wanted a weld can be put in the end of that overly deep notch and then filed fit so there's more metal where there once was air space. Have to do a careful weld though.
Maybe a pinned in spacer could work too. The notch just gets a lil less deep since it was machined to far over near the hammer cam. Know what I mean?

Rifle, I though you just drilled out the Italian cams when they were bad and press fit in a new one(?).    Does Dixie GW still sell Pietta cams?
