You're right about running any machine tool, the setup is the most important part. Like how you reversed the tap, breaking the chip, that gives a better and more accurate thread. I'm not a machinist, but was interested in it, and still am, that's why I'm watching this. Thanks.
I started watching this series because I was interested in both the model and seeing somebody do the work on equipment I can get into my basement. Interesting in many ways. Thank you for the series.
A little advice. You took the time to use a center drill then the correct tapping drill. At that point you should have tapped that hole before you moved the table. That will assure a perpindicular thread properly centered in the bore. No ammount of eyeballing with a square can acheive that. You will find that tapping will go easier and less of a chance of breaking a small tap. My unsolicited 2 cent's worth.
What mill cutter did you use for the bearing recess and how well does it match the bearing material provided? Still trying to decide if I order the castings as it ends up being $200 to get to me in the US.
this is the first time I have encountered BA threading. Do you know if there are UNC and BA equivalents? I was hoping to not have to buy new taps and dies for a Stuart project.
No. It is just a regular ball end mill. The bearing fits flat on the top surface, the circular cutout is a non-contact clearance. When I get to the bearings I am just going to clean them up enough that they don't touch.
he had round stock, why not put it in the bearing saddles and center find from that? unmachined edges of castings aren't good to go by. they are just ballpark, can be 8 or even 10 thou off
Great video! Walking us through the workholding challenges is - as you rightly point out - much more relevant than actually moving metal. Minor complaint: your microphone is too close to your mouth - plosives become nearly-painful when listening with earbuds.

Nice work! I just set up a HF milling machine and I have learned a lot watching this.
Thank you for such an informative and enjoyable series. I am definitely going to order this kit of castings and have a go myself in 2020. 👍😀
Enjoyed this.What type of cutter did you use to cut the bearing grooves.
I used a ball end mill.
what size cutter?
Nice clamping technique.

Tom Mattox it's basically just another thread. Just compare the clearance size and you should be able to find reasonable equivalents.
THANK YOU...for sharing.
was the milling cutter perfectly ground to exact diameter of the main bearing holes so they be perfectly round as per drawing?
No. It is just a regular ball end mill. The bearing fits flat on the top surface, the circular cutout is a non-contact clearance. When I get to the bearings I am just going to clean them up enough that they don't touch.
is that your home machine shop. looks professional
Did you use a ball end mill? To cut the groove?
Yes. Sorry that wasn't clear in the video

this guy needs to watch Joe Pieczynski then learn how to align parts
