  • Tightening a drill press quill.

    I got this little press several years ago for a bit less than $40.00.



    It's handy for smaller holes, I just put it on the bench to use it, then put it back out of the way when done with it.

    Originally the quill was so loose it would rattle around pretty badly. To fix it I marked out and chain drilled for an opening in the bottom of the head, back of the quill bore. A few hits with a hammer knocked out the waste, I used files and a mounted stone in an electric drill to clean up the edge of the hole. That hole was to give access for splitting the casting, and to let the casting flex when a pinch bolt was tightened.

    I cut through the internal wall if the casting the hard way with a loose hacksaw blade with a small handle clamped on the end. All the internal webs were cut through into the bore.


    Next order was to block the casting up as level as I could and drill through both sides with the larger DP, for a 5/16th pinch bolt. I found later that I didn't have it very well leveled, but who's going to notice a hundred years from now.


    After reassembly, I tightened the bolt so that the spring would just raise the quill and I couldn't feel any side shake. That made it a much more friendly machine to use.


    Edit; Well I see I still don't know how to post images. I don't post them often enough to remember how. I'll try to repost them later.

    Unfortunately, all your pictures come out at about 1 inch by 1.25 inches, too blamed small to see.... I note that they are labeled "small" in their titles....

    You can safely use VGA picture sizing, or thereabouts.... 640 x 480 is fine, and the usual forum will take a bit bigger also. At that sizeing they should come out about 3 x 5 or so, easily seen.

      It looks like you copyed the URL of each thumbnail. You need open the page the image shows up on and copy the URL from there instead.

        A small change fixes the size problem.

          Sorry about the pictures, they have been giving me fits. I didn't want to post links, thought I would be posting images. I'll see if I can edit out the links and try to learn how to post images. It'll be a day or two, got other obligations tomorrow.

            Thanks Arcane;

            That's what I was seeing when I made the links. I need to study it more, but gotta hit the sack now, places to go and things to do tomorrow.

              You can only post 4 images per post, but heres how:

              You take the url and you put <IMG>http://Yoururlhere.com/something.jpg</IMG> tags around it

              Except this board uses [ and not < but I can't use [ without it thinking its an image tag to be processed.

              Or click the little button that looks like two grey mountains over a yellow backround (With a grey sun?..) and has the tooltip: "Insert Image" when you mouse over it (may need to 'enable scripted windows') when IE asks you)

                    Heh. Use the [noparse] tags not to be parsed such as the [img]/[/img] go here [/noparse] tags.

                    So, Arcane, how did I do that?

                    A little recursion goes a long way.

                      Ah, I used the Code tag, Assuming that code would'nt be parsed. It was, And ended up editing it to just use <>'s.

                        I learned it from you quite a while back! Where you learned it is anyone's guess.

                          I learned it from The Art of Computer Programming by Donald E. Knuth. It is the bible of computer programming.

                            Looks like a good fix, thanks for sharing.
