Project: drill press depth stop Canadian buffalo 15

[schor]

So we have had a bit of a discussion on projects in another thread. I'm going to start a project thread (as depicted in the subject) in hopes we get a project forum with threads on different members projects which are long term thing. Not just like project of the day, etc.

So my first project here is a drill press depth stop for a buffalo 18 drill press. It seems these depth stops died in use over the years, or were just removed from some reason. In any case a friend needed one so I built it. At a loss if you count my time, but to me as a hobbyist, it as free time as I learned so much through the process.

It all started with a simple question in another forum about someone needing a depth stop, and I figured it would be a good learning experience.

So I came up with a plan. Using sketchup I came up with a model of the main collet.



More to comes, gotta keep the suspense up a bit don't I?

So then I tried to figure how to build it. Cut the hole to exactly (well almost) to the quill diameter and then cut it in 2 and place some hex screws countersunk as much as possible.

I wanted some xperience knurling so I set upon some aluminium stock, got the tool centered and ran it at my normal turning speed (feed at .005) I was surprised it worked so well.

Next is making the knurled stops.

Seems those pics are out of sequence, let's see if I can get my stuff together for the next post.

After a bit of touching up with the parting tool I parted off the knobs.

Your first three pictures are broken links to me. But it sounds like an interesting idea, I have a 5 speed drill press, and it didn't have a depth stop when I got it. Thanks for the inspiration.

So with the stops done I was onto the post. This was mostly turning down some round bar aluminum and the threading it all with a hand die. 1/2" 13tpi

So the post is done with manual die for thge whole thread, thank god it was aluminium.



Next is onto the collar. Start with some 1/2" aluminum plate, cut off a piece and mark it for the holes. Keep it all square for most of the next operations. I used a bi-metal hole saw for the quill hole, worked fine, as only about 20thou out which is fine given I'll be taking more than that out with the sawcut later.

Thread the hole for the post.

A little out of sequence or I forgot a whole part here. I drilled out the holes to tap size, then drilled clearance holes down to .010 from the top of the split, then counterbored for the cap screws. Then I cut the piece.

Next step is to tap the holes for the cap screws. With the piece already drilled to tap dimensions and clearance holes drilled and counter bored for the cap screws I can now blind tap the holes.



Everything went together, I had to re-counterbvore the holes for the capscrew heads a bit more. Took the rought part to the disc sander and cleaned it up, then some hand sanding/filing and it was good to go, almost.



Final assembly with a set screw. The setscrew is needed so the post will not turn off the collar while adjusting the nuts. A flat on the post will ensure it stays snug.

Serial #? :LOL:

I was sure you would mill a flat on one side of the rod and stamp the depth 1" 2" etc. A bit surprised you didn't do that. You sure did great work though!

Nice project & presentation

Beautiful work! The knurled nuts do look nice ... BUT ... I've found them to be a bit slow when it comes time to make large adjustments. I have a drill press with a similar setup, and I replaced the original nuts with pushbutton quick-threading nuts. I use the 3/8-16 plain hex nuts (McMaster-Carr 98150A150), and can even use the hex flats for fine adjustments ... 1/6 turn (1 flat) = .010" (approx.)

McMaster sells these in sizes from 1/4" to 5/8":

If I had a mill I would have done that. Last time I tried to end mill on my drill press I pulled the chuck off.

Still searching for my first mill, needs to be a smaller one and needs to be in the $500 range. I'm just a hobbyist.

Thanks, I have seen those nuts before but I made the piece for a friend for $30 and to gain experience. Part of the experience is the knurl, maybe I can try to make one of those nuts someday.

There's a fellow in my area who posted this on Craigslist. Not sure if he still has it or not.
