Sir, concerning the diameter. Half of 6.496 is 3.248. At 2:53 of the video, you entered 3.284 for the radius.

@gropius6070 5 ай бұрын

Also, it wasn't shown, but for that 7th hole is it necessary to enter the radius again on the DRO? In that case, it will be an *interesting* bolt hole pattern if the radius is different for one hole. The number is written as 3.248 on the diagram/layout. 😬

Keith, as others have said the bolt hole radius you drilled is wrong. You typed in 3.284” when it says 3.248” on the drawing. So you’re large by 0.036”. Hope whoever makes the motor mount sees this and compensates, and hope that it’s not a critical dimension!

@A.Hidell 5 ай бұрын

On the printed diagram of the layout, you have written a diameter of 6.496 inches. That makes the radius 3.248 inches as correctly written, NOT the 3.284.inches you entered on the machine. The mounting plate will be out if it has already been made.

Keith, I've never had much luck drilling on a step surface. They always drill off center. The video shows on both those holes they were forced off center on the low side.

It would not have needed much more than just a little room for either nut or bolt head clearance. Good luck!

I agree, surely as you said, using an end mill would have relieved that flange edge and made a nice flat surface for the center drill to start, also I noticed Keith was not rotating the tap backwards a small amount each time to clear the chips and why did he not get a shorter handled tap wrench to save all that fiddling about.

If you use a tap follower anyway I'd have no problems using a wrench on the tap.

Re the alignment mistake, it's feasible that the motor mounting flange will need elongated slots anyway to adjust initial gear lash and for subsequent wear. Many windlasses have that.
