This is a great little gadget. In large part to KZbin mentors like you I found my way into a tool and die maker program at technical college. As part of my course work I have to put in a certain amount of machine time every week. Part of that time is to work on the projects provided by the teachers but the rest of it we have to come up with ourselves and I've spent the last month working on all these awesome shop aids you've shown off and they are the handiest things to have. Thanks a bunch for not only inspiring me but also teaching me a lot that my actual teachers haven't.

Neat solution! I have to admit that i didnt see a problem picking up the edge without the gadged until you explained that this will work on any angle. If the workpiece is at 90- deg. you can do it the normal method picking the edge on both sides and divide. Thanks for the explenation! If I ever get a mill this will for sure come in handy.

With a little trig you can do it for any known set of right triangles. You just drop down a known amount from the top of the part and use the base of the opposing triangles to figure out the % of the total amount to deduct for each side.

I think if I was going to use it with one particular edge finder, I'd make it so that I ended up taking off either 10mm or 20mm in total. It simplifies things for my simple mind. Although as far as I can see it will only work with a 90 degree angled workpiece. Anyway, its been added to my homemade workshop tool list.
@machinists-shortcuts2 жыл бұрын
For workpiece angles other than 90 deg. An accurate "x" shaped cradle could be used which has a stiff pivot in the centre. This could be fitted onto the peak and a pin laid in the cradle, then the centre of the pin could be found. This will work on any workpiece angle but the peak must be set with the angles equal either side. I'm sure with a bit of trig it could be used with the peak leaning to one side.

That will work for a 90 Degree edge only. All other angles will either need a special one of these tools or different tactics and some trig calculations. Of course optical can as you said Stefan, get you close. Also the shallower the angle with a tool like this the more likely an error can creep in because it becomes more difficult to feel the tool seat securely over the apex. Just a couple of long after thoughts, Cheers from John, Australia.

If you have a large part that has a chamfer too large for this tool, then you can use a vee block with a ground rod clamped in the opposite vee. Again it will be 1/2 the edge finder diameter + 1/2 of whatever size the ground rod diameter is. Stefans tool and the vee block will only work if the the corner that you wish to find is at 90 degrees. If you are unsure of the accuracy of the vee block, it will pay you to check that the vee's are in the center of the block. Do not panic if they are not, make a note of the out of center error and take this into account when edge finding. This will still be more accurate than doing it by eye, especially if the edge has a chamfer. Hope this helps.
@stanrogers56135 жыл бұрын
The vee block will only work (without additional math) if the workpiece is at 45 degrees. Any other angle will introduce an offset.

Great idea, not sure if I need one but will make one all the same. If you don't have a disc mic, as most people wont, if you sit the blank in a square, while it is being machined, you could use a depth mic between the cut surfaces and the square;s arms. At least that is how I shall do it, even though I do have a disc mic.

Stefan Gotteswinter Or, put a gauge block in the cut out and measure the OD with a mic.

Great gadget to have in the box! Finding the theoretical intersection of two planes can be tricky, especially when the work is at odd angles.

This helps correct for edge finder error. Thanks Stefan!

if you have a work piece angle significantly larger or smaller than 90° then you got problems. What I suggest is that you make another one out of two pieces that rotate to fit larger or smaller angles. Done right, the tool's radius wouldn't change due to rotation. What do you think, Stefan? Is that something that could work? Thanks! :)

gentleman, just one question, what if the object is not perfectly square? say the corner you have to work with is 92 degrees, the packman will have a small gap sitting on the edge what if we do a say 120 degree cut and no relief hole on the packman, let it see saw on that top corner, the idea is just like the old trick use on the lathe. chuck a dead center and tailstock another, put a metal ruler in between. do you think it will work as well?
@Gottenhimfella5 жыл бұрын
It would be essential to remove any burrs whatsoever on the male corner of the workpiece (ideally the faces would need to be carefully stoned in alternation and then the corner stropped with leather, or the palm of the hand if you have tough "manual labour" skin!)* , and it would be hard to get a sharp internal corner on the button ... *Then as soon as it's no longer required, use a stone to chamfer the corner which will otherwise be dangerously sharp. So I guess whether it "works" depends on the accuracy you require. But I reckon the theoretical basis of your idea is sound.

Gene Elliott If it is below 90 degrees, mill off two grooves in both sides of the gap of the tool and use gauge pins on both sides - that'll fill the missing degrees. If it is over 90 degrees, use one gauge pin to fill in exactly at the "theoretical corner."

Clever idea, and as always, the execution is exquisite - but I think if you find yourself reaching for this often, someone should have a talk with your designers/engineers about using work holes. Dimensioning to a theoretical sharp point is fine as a reference, but really shouldn't be relied on for anything that matters. And yes, if you just ground a corner dead square and sharp, it's probably pretty close to actually being a sharp point - right up until it gets deburred or used, and then it isn't anymore. Then it's a theoretical sharp point, and someone would need a clever tool like yours to repeat your setup/measurements. Work holes (when you can get away with them) don't have that problem.
@JaakkoF6 жыл бұрын
This angle hole problem creeps up in mould production work constantly, usually the holes are at an angle of 15-20 degrees. Or a hole. The problem is, how do you dimension the hole location and also find it easily when machining, when it is the only hole? Or when the workpiece has maybe only one 90 degree corner in it? The easy answer is to dimension from known edges, be it theoretical point or not, and have a tool just like this to easily find it on the machine.
@billyc25727 жыл бұрын
the best way to do this, is edge find the adjacent edge, in the video, the edge on the right. measure the thickness of the part, move over that distance and half your .200 edge finder (typical) and Bam Bob's your aunt. no extra tooling needed
