Hello all, I wanted to know what is the ball-park patch diameter, not thickness for a 62, cal. rifled barrel. I am getting ready to make some patch cutters, would be .610 ball. Best to you and yours; Ravenwolf;

star a ball and patch material in the muzzle but instaed of cutting the patch mark it all around the muzzle then pull it back out. you'll have your size

Hi, yes that will work, I thought I read on the forum where there is/was a formula? ect, I have a bunch of old hole saws like 1.250 1.312 1.375 1.437 1.500..... I cut my own ticking, so as I get ready to go to 62 cal. I wanted to decide which one to machine, Maryland season in six days, I can not sleep. Ravenwolf;

Ball diameter times 2.57 will get you pretty close to a patch the same diameter as if it were cut at the muzzle with a knife.
And, there's nothing wrong with square patches which can be cut out with a straight edge and scissors.

The patch cutter that i use for my 62 is 1&3/8th.
-
That's about right - 1 1/4" is probably perfect, with 1 3/8" just fine. Even 1 1/2" at RB uses will work too.
For the .58, I use patches cut with a 1 1/8" arch punch. I've also used those in the .62 smoothbore, but they are getting on the small side & 1 1/4" would be perfect, again.

Raven,
Many of us up here use a tapered bearing race and a 1 7/8"(or larger) ball bearing ball as a precut patch maker. It's real easy to knock off a hundred or more in half an hour.All I do is put the cloth over the race,bearing ball over the cloth and race and a sharp tap with a hammer and voila! I have a cheap 10 or 15 pound anvil as a base for the race and ball. Check an automotive brake or front-end shop.They toss 'em so they're free. I have them(races) from 1 inch to 1 1/2 inch diameters.Machine shops have the large bearing balls.
After the hunting season is over you might like to give it a try.Works good for me.

A bit of topic but several years ago at a local gas station,there were some punks trying to make an old man buy them a case of beer.He told them no and to leave him alone. Well,one these brave lads drew back his fist to hit the old fellow and learned quickly and painfully what a devastating weapon one of these big ball bearings wrapped in a stocking was.
Never mess with an old guy,he might take offense and do something about the situation.

Daryls,
In your picture,at the top left is a piece of pipe. You gave me a piece of it or similar, suitable for my .50. Got any more that is the next size bigger? Thinking ahead for the 28ga, or .55 cal. The M&G barrel I have is .550.The Getz ,I'm not sure. Sorry Raven.
Thanx Daryls, for posting the pix. It sure helps with my explanation.cheers

That's why I posted it, LB- to help with the explanation. That is my 'quota' of bearings, etc. The large races make good ones for the .62 or .58.
A 1 1/8" arch punch will work well for the little smoothie, or the larger race- whatever. That black material is UHMW = HDPE in the states. Redwood Plastics will sell you a block like that for about $10.00 - or trade one for a box of suds on Friday.

I would have to be at least 1/2 the circumference. ie 1/2 x .62 x 3.1417. To equal the same diameter as a ball pushed down just inside the muzzle and then the patch cut off, add .62
So the formula would be (caliber x 3.1417 x .5) +caliber=patch diameter
to shorten the formula take 2.6 x caliber
