Your scale reads in pounds and ounces. Ball started at 15 pounds 2.5 ounces. After drilling ball weighed 14 pounds 15.2 ounces. A difference of 3.3 ounces.
Hi Vincent, thanks for your video. It’s very helpful to know that step drill will reduce the heat and in turn core swell. I’m going to try that as well as try to drill the hole faster. I suspect I drill too slowly and that causes more heat. On another note, I noticed that you have four-fluted end mills. Where did you purchase those from? I have a couple of two-fluted ones but they don’t seem to cut very straight when I use them to drill ovals.
So those end mils were there when I took over the shop 3 years ago. There is a guy that sells them on Facebook. Name is Wyatt Nguyen he is in Vietnam but has a good reputation for drill bits and such.
So you use a stepping method for drilling the thumb hole but then drill over an inch deep in only two increments and with moderately high pressure? How does this reduce friction heat and core swelling?
The drill depth is slug depth which is about 2 3/4”. By stepping the bits it doesn’t get as hot as if you just use the 1 1/2” bit for interchangeable thumb. A hole still gets warm while drilling due to friction. So stepping the bits helps minimize the amount of heat to the core, also stepping the bits make for a straighter hole. Hope this helps you. Thanks for the reply.
Ya I know Jeffrey. I totally blew that. When you’re doing these type of videos you’re bound to make a mistake here and there. Thanks for the reply and for watching the video.

You’re right Michael. I definitely missed the actual amount of weight moved. Good catch sir..
Exactly my thoughts. .8 oz less than 15 lbs plus the 2.5 it was over makes it 3.3 oz less in weight than the original.
@@willjames6437 makes more sense why they sell them at like 15.3
great video, good to know
sooo imma buy 15 soo i can technically have a 14 pounder
mmm glad i came across this video
Nice video, keep it up
Interesting seeing it measured out like that

Thanks @@vincentortiz2609 ! 😀

2.5oz and 0.8oz does not equal 1.08oz
