<div dir="ltr">Another way to do this is rough grind the threads off on a bench grinder and then finish on the lathe. As long as you are careful no to go too deep on the grinder, it makes the lathe work a lot easier.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Aug 9, 2016 at 9:20 AM, John Miller <span dir="ltr"><<a href="mailto:jem@milleredp.com" target="_blank">jem@milleredp.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On 8/8/2016 6:23 PM, Dave Cavanaugh wrote:<br>

Put another nut (or two) the the same size as the bolt head on the<br>
threaded portion, run it down to the bottom of the threads, align all<br>

This worked for me as well.<br>
<br>
Done it a few times, but most notably I've got a spare-tire mount on my trailer that's got a 1in (I think) bolt thru a plate to retain the wheel, I cut the threads off the last inch and a quarter or so of the bolt, milled flats on the sides, and drilled it for a padlock.<br>
<br>
Cutting the threads off will require a fairly high speed and shallow cut.<span class="HOEnZb"><font color="#888888"><br>
