RE: HELP... My bow sounds like a rifle
thenuge... Make sure they are using a double pull press, putting pressure at the extreme ends of the riser. Never let them pull on the middle of a machined aluminum riser. They also need to have the bow centered in the press, not riding against the wheel end of one limb and the butt end of the other. They should back the limb bolts out a few turns before pressing the bow. There are all kinds of bonehead maneuvers someone can pull with a press and screw up a bow!
You' d probably never notice a slightly bent riser. I' d bet the majority of machined aluminum risers probably ARE a little bent. No way to tell for sure without special tooling.
When your centershot makes a major change after it' s been in a press, that' s a good sign it' s bent. If you hold it up by the end and sight down the string and see that one limb tip is twisted off to the left and the other is off to the right (or vice versa) you' ve got problems. If factory spec string/cables suddenly seem too long for the bow, it could be bent.
If you' ve got a forged magnesium riser, they are nowhere near as susceptible to bending as machined aluminum.

RE: HELP... My bow sounds like a rifle
Of several concerns I would have when taking my bow to a bow shop that does not have a long-standing reputation for good service and ALL the personnel being competent, the use of a bow press would be my ultimate concern.
In 1996, I did let a shop put new cables and string one of my compounds. Afterwards, I noticed that the limb adjusting bolts were not adjusting the same. The adjusting bolts were extremely hard to turn. I suspected that improper placement of my bow into the press put too much stress on the lower section of my limbs and possibly damaged the female threads in the limb pockets. I knew I would not be able to prove that the shop was at fault so I purchased a new bow, being the replacement cost of a riser was half the cost of a complete new bow and time was of the essence.
Not all shops have a press that meets the needs of ALL bows, especially the short ATA bows. I would be concerned that the person putting my bow in the press would not take the time to readjust the press to fit my bow. I would also be concerned that the person is not completely knowledgeable about the use of a press.
I was not present when it happened, but I saw the aftermath of an improper use of a press. Apparently, as told to me, the employee did not back off the draw-weight of a bow with a solid aluminum riser. The press blew both ends of the riser off.
On machined aluminum risers, improper use of a press can bend the riser. You can also overstress the lower part of the limbs.

Actually, I think it' s making a good case for a stickbow and not needing all these high falootin' specialty tools in the first place.

Now wait a minute, are we not supposed to use the leg method on recurves? thats the only way I' ve ever done mine and it' s worked great for about 15 years now. My recurve is also not one with removeable limbs.

RE: HELP... My bow sounds like a rifle
Hmmm..and how many guys have twisted a recurve or longbow limb by using the " through the leg" stringing method instead of a quality stringer?
$10 vs... How much does an Apple run these days? $150 for the basic cheap one? Nearly $300 for the good one? That would buy an awful lot of stringers. Probably a bow as well.
Actually, if the manufacturers would stick limb bolts in their bows that are long enough to totally relax the bow by backing the bolts out, there would be absolutely no need for the individual to own anything more than a set of allen wrenches, screwdriver and pair of pliers.
Remember the good ol' days when you could do that? Back the limb bolts out, completely disassemble the bow, clean and lube everything and slap it back together. No press, no sweat.

Huntmaster, the step through method works fine, IF you know how to do it properly. Problem is, not many people have the technique. The step trough method, improperly done, has ruined more recurves than any other single thing.

Going back to this would be SWEET!
Hey Art, there' s your side line business. Retrofit Limb bolts. A little drill and tap, and vioula!

RE: HELP... My bow sounds like a rifle
Well I took the bow back to the shop today. The guy that was ther today looked at it and knew instantly what was wrong. The other " technician" didnt twist the string when installing. This guy put it in the press, took the string off, twisted it a few turns and viola I have a quieter bow and the peep doesnt twist when I draw. Plus my anchor point feels right again. Thanks for the suggestions anyway.
