I finally got the Z-4 chuck but neglected to order the insert. I thought it was direct threading to the spindle. This time I talked to a representative and they were very helpful and sent the adapter the same day. Shouldn’t take too long.That 3040 is a beast. I hope you get it up and running soon. I also bought my Rikon 1824 from Acme. It was 10% off and free shipping at that time.
The wheels I ordered, Dec. 12, still have not been sent.
However, I ordered the Tool Rest Extension Knuckle and Bed Gap Insert from Highland Woodworking and it will be here next week. Excellent service. Not as cheap as ACME but very knowledgeable about their products. I’ve ordered from them in the past.
