Default Drilling large hole over small hole or vice-versa

Good day

I have a cheap DP and when I want to change the table height I have to unlock the table and while turning it left/right pull it up or push it down.

I like to prepare a bunch of "Knobs" in different diameters and when I make some jig, I just grab them "of the shelf" and used them.

I cut the knobs with a "Hole saw" that has a 1/4" drill in the center.

But, I had a problem, sometimes I had to enlarge the 1/4" hole to 5/16" or 3/8" (here it's simpler, 6mm to 8mm or 10mm without using 3 denominators) and had to drill a larger hole for the bolt head, washer or T-nut.

Another problem was that the drill length was different and to change the drill, I had to lower the Drill Press table and come back to the center of the hole.

So, that's what I did

Regards
niki

Hi niki

I also make my own knobs for jigs but I do it a bit diff., the key for the ones I make is the 1/4" center that all how saws put in... I always put in a small center hole in the block (index hole) and drill that hole out for the tee nut then it's always on center for 1/4,5/16,3/8,1/2" then just let float on the press so to speak when I drill out the center hole.(tee nut or carr.bolt etc.

Here's a snapshot of the ones I make quick and easy

Hi BJ

I saw your knobs at the time that you posted them. You made a jig for cutting them.

Too much work for me, I just drill once with the hole saw and finito la comedia.

I found that for my old hands and fingers the best shape is simple round and than, I glue around anti-skid tape so I have very strong grip.

On the pic you can see that I made them almost like yours but I did not like them and later replaced them with the round type (those with the red anti-skid tape).

Well Niki, yet another simple way to make knobs. Both you and Bob are such lateral thinkers. The sheer simplicity of you're method using the most basic of tools is to be commended. You're ideas and photo. shoots are just begging to be put into book form. One final comment, you're command of the English language is quite outstanding for an Englishman, let alone an Israeli who spent years in Japan and now lives in Poland!

Thank you Harry

Forget about a book, I prefer to spend my time in the garage...

As you know, the Jews were "kicked out" from many European countries and moved to other country.
At that time the expression "The wandering Jew" was born. So I'm just continuing the tradition...

Another joke about the Jews is:
The Jews are like fertilizer, if you put it a little bit here, a little bit there, it fertilizes...
But if you put it all together in one place...it stinks...

thanks! this is great..

taking your idea one step further.. could you mount a router UNDER the drill press and use a metal "dowel rod" mounted in the drull press as a guide for duplication of parts?

ie.. essentially you would be building an "over/underarm" router!

and would that allow you to "flip" the item you were routing? ie.. make a left and right? item?

sorrry if I am too far off

its late.. and I cant sleep..

either way.. thanks.. this idea is great..

Thank you Sawzall

It does not look possible to me, you have to be able to move the table to all the directions and the table is limited to left/right (circle) motion only.

Niki,

All I have to say is that between you and Bj, I have enough shop jig projects on my list to last a life time

This is yet another fantastic idea.
