I know this post is 2 years old but I need to ask you a question on your power chuck, I inherited a sl 3b in my shop with an old chuck that is worn out and won't hold concentricity. looking for a2-6 10inch chuck but spindle tube threads are different than any a2-6 noses I can find....No marking on the chuck either..
If you can help with any info, let me know....thank you |
