These items are in good shape and have not been used recently. The reason they're for sale is that the chuck (adapter) does not freely seat completely on my Robust lathe spindle; whereas, there were no problems with seating on the spindle of my previous PM3520. The 1"x8 adapter also seats perfectly on 1" spindles of several mini lathes it has been used on. Sale price for the collection is $175 + shipping costs.
