Oval Maker II

How often do the drill bits need to be sharpened?
This depends entirely on how much the bits are used. As a rule, you can feel the bit not cutting smoothly or feel the bit getting warm. When a bit is sharp, you can hear it making a crisp cut. The bits that you use most should be sharpened at least once a year.

What is the best way to drill on the Oval Maker II?
We recommend that you drill the fingers first. Simply mark the center of grip and where you want the fingers to be, then drill the finger holes. If you are using grips, place them in the holes and take a span rule and arch a line from the middle finger, then the ring finger. Where the lines cross is where your thumb will be drilled. There are some very big advantages to drilling this way. First, you do not need to maintain 2 sets of measurements, one full grip and one cut to cut. Additionally, if you are using a thumb slug, you can start the thumb hole with the proper size, then stop and insert a 1 1/4” bit and drill the hole, then remove the bit and clean the hole. Put some glue half way down the hole and then stack a second slug on top of the one you want in the ball and pull the spindle handle like you a drilling a hole until your slug is in place.
Then place the desired bit for the thumb hole and drill the thumb. When this is complete, set the pitches to zero and loosen the clamp ring and place the slug straight up in the jig and tighten the ring. Now with your plug trimming blade, carefully trim the slug to the surface of the ball.

What makes the Tri-Oval System better than vacuum systems??
Vacuum systems only secure the ball from the bottom, when under ideal conditions this can be very secure. But when those conditions are not ideal, like when engraving on the ball is over the seal, or maybe the ball is out of size, then the vacuum has a hard time making a seal. If the seal is lost while drilling, the ball will come flying out of the machine, damaging the ball and possibly injuring the operator.

The Oval Make II has a removable ring that holds the ball on the top. This ring is mounted on a hinge with an elliptical hinge system to account for variance in the size of the ball. The ring can be put in placed and removed in the same time it takes to turn a vacuum machine on! Because the ball is secure from the top and bottom, the operator is safe under any circumstance.

	Commonly asked questions about oval milling Do I need special bits for drilling oval holes?? Nope. Special end mill bits are very expensive. We manufacture our own drill bits specifically for drilling bowling balls. When used properly, they will provide the same accuracy in cutting oval holes. Like any cutting tool, it is very important that the bits be kept sharp at all times. The speed that is used is also very important. We recommend a cutting speed of 450 to 500 RPMs. Remember that the faster the bit is turning, the more friction and heat is created, reducing the life of the bit.
