Thanks thehomeengineer! We've added your ER25 Collet Chuck to our Workholding category,
as well as to your builder page: thehomeengineer's Homemade Tools. Your receipt:
You had my attention with the ER-collet-to D1-4 fitting since you first introduce yourself and provided the website Practical Engineering . I currently use a ER32 CNC collet chuck that is 6" long by 1.5" diameter with a smooth straight shaft held in another tru-adjust 6-jaw chuck. It works okay and can be set up to be within 0.0002" TIR by rotating and clamping the collet chuck into the best position for minimum TIR but not a very fast setup. Ideally, I would like to make an ER32 collet chuck that mounts directly on my D1-4 lathe spindle and do away with the hardened 6-jaw chuck jaws holding another hardened collet chuck, with a potential for damaging the hardened surfaces.
Thank you for posting the D1-4 collet chuck.
