    What bearings did you use for the bellcrank?

    Some tapered roller bearings. I can get the number off them when I get it back.

    Timken LM11710 & LM11749, these were the ones I installed. The bore is .6875. I love how Timken gives dimensions in millimeters on their website but all tapered roller bearings are built using standard dimensions.

    Thanks Mike, I believe those are standard wheel bearings. I've got this on my to do list once I get my mill set up.

    Howard here is what it looked like clamped to my mill. Kind of scary but worked out OK.
    It is bolted to a 1-2-3 block that is clamped to the table with gage blocks under the round part and 2 tow clamps against the arms pressing it to the table. This was actually quite rigid.

    :shock:

    Rube Goldberg ain't got nuthin on you Mike :)

    I'm no wheres ready to attempt this myself but i have been thinking about how to do it; what I'm thinking is a pice of 1/4" plate wint a hole in the middle to slip over the arm & bolting the plate to the table.

    I have a rotary table , would you recommend using the rotary table & an end mill to cut away the bore or (what I'm assuming you did) centering the bore under the quill & using a boring head?

    I did use a boring head, the plate will work but I trued up the faces of the hole as they had wear marks and would not sit flat.

    Ah, hadnt thought of that, I'll check mine for that.
    Any thoughts on the boring head vs. the rotary table?

    Wow! As someone who knows very very little about what you do, Mike, I have to say that it looks both scary and impressive. The outcome certainly seems impressive. I wish I could apprentice with you for a few years.

    Howard I did it with the boring head, the main reason was ease of setup, the part would be hard to set up on my small 6” rotary table. If you have a larger one go for it. I like to use a boring head because it is easier for me to control size and guarantees it’s round with no interruptions.

    So as long as this seems to workout ok, I have no problem with doing it again.
