Some barrels you can, if they have enugh outside diameter.
What kind of barrel do you want bored.

[cockerpunk]

you mean freak bored, or rebored to a different ID?

[athomas]

Yes, you need to clarify whether you mean actually bore out a barrel for inserts, or bore out a barrel to a larger id.

We used to use 12 gauge shotgun barrel hones to enlarge our barrels back in the late 80's and early 90's when paint was large bore and barrels were tighter because of closed bolt ball roll out issue that pumps have. Quite often the barrels were too tight and accuracy suffered so we honed them out. Many thought the accuracy increased because of the smoothing of the bore, but it was the enlarging of the bore so that the balls barely touched in two spots opposite each other that made the difference.

ANS thundr pig 9". its .0689, i want .0691 or .0692. or maybe even .0693. miami weather tends 2 swell my balls...

ANS thundr pig 9". its .0689, i want .0691 or .0692...Use a 12 gauge barrel hone to enlarge by a few thousandths.

Edit: I fell into the decimal trap but the result is still the same. The 12 gauge barrel hone is the way to go.

Aren't you going to lose your anodization if you do this?

[athomas]

Yes, any boring and honing removes the anodized surface. You can have it redone if you want.

Use a 12 gauge barrel hone to enlarge by a few ten-thousandths.
awsome, thanks much...

hi, thanks. do i use a swab or metal tip & for long many strocks????

was it the 180 or 800 grit? did you use lube when honing? thank U so much...

there is just so much wrong with this thread

there is just so much wrong with this threadIt sounds bad doesn't it? :eek:


2BAD4U: I always use a lubricant when honing or boring. It helps keep the hone clean. Ideally, you should have both grits, one to start and one to finish. Seeing as you are taking off a minimal amount, the 800 grit might be fine on its own and it will leave a nice smooth finish. Aluminum will clog it in a hurry so clean it often.

Lets start by fixing this.

Your decimal is off. Your barrel is a .689"(you need some type of bore gauge or pin to give a further precise measurement). Also If someone knows the barrel tolerance that would be good to know too(+/-.0005"?)
Machine boring to open it up .001".003" is almost flirting with disaster.

My recommendation is Go to your local fastnel/granger/msc and either buy a expanding hand reamer(with a lock) or buy individual reamers in .0005" increments of the sizes you want. (I would suggest individual reamers seeing as you most likely don’t have a gauge to measure with.) Make sure you give the bore a light honing to remove light imperfections and any burrs you may have created.

If it was me... Over bore it on a machine to the freak insert od size and use freak inserts. Paintball size will differ day to day and week to week. there’s no sense in reaming up to a .693" when next week ball size will be more consistent to .687" or less. The interchangeability in having correct sizing is what makes the freak so well known and proven.

And if you really don’t know what your wrapping your head around find a machine shop(job shop) that can help you out. There’s plenty of machinist on here including myself that can give you better insight to what you’re looking to do. Just do it right the first time.

There’s not much anyone can do about your swelling balls...(maybe put them in some ice.. but that tends to make them more brittle) :rolleyes:

Hope this helps. GL and let us know what you do. :cheers:

Super_Stanchy over at www.mcarterbrown.com will bore out your barrl to accept Smart Parts Freaks inserts

I highly recommend his work, he is located in Camas, WA and has his own Airsmithing Section

You can't go wrong, for $ 35 you can use all of the Freak inserts - hav the Total Freak Kit with 8 bores and the Reball insert so its like having nine barrels
