My Sherline is from the 1990s, back when there was no saddle lock. I ordered the 4017U upgrade to add the lock but before I got it out the bag I read on here that there's an even better option, the 4017Z which includes a backlash adjustment. So I swapped it out for that. So far so good. Step 2 of the instructions says to remove the countersunk screw that hold the whole leadscrew assembly on. I cannot get that screw loose. I've been dripping Liquid Wrench, and now Kroil on it for about five days, but it will not budge. The only Allen key that fits is 1/8", which fits the matching screw on the Sherline lathe.
I throw myself upon your mercy in the search for ideas. Any thoughts? Other than patience, which is possible, but getting a bit thin.
