Actually, the problem can be cured by making the guide body in two pieces. A base and a cover in effect. The base is a flat plate with the slot for movement. The top is a box with just a partial slot for the head of the screw. The fun part is how to drive the screw, that is done by using a worm screw setup driven from the end with a hex shaft. In operation, the worm slides along the shaft as you move the body while it stays in engagement with the head of the screw. Then you turn the hex shaft to tighten the screw. A device that even Rube Goldberg would love.

As a mechanical engineering student, I'm super impressed how well you seemlessly explain everything as you go along. Keep it up man👍

I have an idea to fix your flexing problem that doesn't require hardening (although heat treat would very much help). The bars you made that stay square to the table would need to be a little bit thicker, but you could machine a .075"x.075" ledge into the parallel sides bottom edge where it contacts the table. Then, recut the spreading dovetail piece so it is identical to what you have, EXCEPT have a .065"x.072" backstop sticking up on either end (poking up out of the slot) to fit the ledge you machined into the bar. It would clamp your parallel bars from the outside and prevent them from spreading apart. The .010" difference in height prevents it from lifting the bar when tightened to the table due to each half rotating out and up, and the .003" difference in width keeps the ledge recessed behind your parallel surface for your parts so it doesn't interfere at all. Assuming that it helps keep your bars from bowing, it will also make it easier to snug them to the table! It might make more sense if I sketch it so if you'd like to see what I envision just let me know how to get it to you. Thanks for making such creative projects!

Thanks Bradley. That's something that I totally understand why some people do. On a project this big it's hard to hit all the details in one video. But with some clever organizing/titling it can be spread to 4 videos (5 if you count the toe clamps) like I managed here. Anyway I really appreciate the encouragement. I definitely feel the pressure to make things faster/snappy/etc.

I think the dove tail has to expand before the guide is clamped. The dovetail sets everything square to the slot. Once square, then the guide can be clamped square to it. In your version the guide is clamping down to the plate surface before the dovetail can pull everything square. To solve this, I think you could have a bolt within a bolt. A shorter larger diameter bolt could thread through the half round and push off the bottom of the dovetail (like a set screw but it needs a bolt head). This same bolt would be tapped for a longer bolt. The longer bolt is for tightening the guide to dovetail insert. Both bolts could be tightened independently. You would need a box wrench and Alan key, like you adjust values on an engine. For bonus points you can do a side project to make an equally fancy tool.

This looks like a great concept. Thanks for sharing it. One possible idea for round two: Ditch the slot in the guide bar, maybe replacing it with a series of holes so you have a discrete set of adjustment points on that axis. Less flexibility in terms of adjustment, but that should mean the bar becomes much more resistant flexing as it tightens down.

@InheritanceMachining

This video and glas blowing has taught me one thing: The universe is a lot squishier than I would like it to be. If the part is non- functional anyway you could see if that air hardening feature can be leveraged for some added rigidity.

For the "bow" problem You could make the top part of a heat-treatable alloy (do the heat treatment) and increase the wall thickness.

@camothrowback1526

10 ай бұрын

Was thinking about the wall thickness because essentially having your wall thickness thicker, the amount of deformational effect from torquing down the part should become minimized. That however will depend if you increase the size of your screw and of course you will have limitations on the level of accuracy you may want to round corners with (e.g. workspace use), but the heat treatable alloy is a good thought.

@jeffreyhayashida2355

Increasing wall thickness is definitely the way to go here. Deflection is a cube law to thickness. The heat treatment is a good thought, but in general will make the material harder, but not any stiffer as Youngs modulus/stiffness of a material is only minimally affected by hardening

I have a few thoughts for v2 - 1. Harden the parts to prevent deflection. 2. Since the width of the part isn't important, make it considerably wider to allow for more strength (to prevent deflection when tightened) and allow more surface area for the friction to the table. 3. Do they need to be that long? Shortening them would reduce the requirement for squareness and since they are fences for locating the part and your sweet clamps are holding them, maybe shorter parts will reduce the deflection issue.

@Malex-lt5mv

10 ай бұрын

Hardening won’t prevent deflection, the modulus of elasticity is an inherent property of each material and unaffected by heat treat. It will change the force required to “set” a deflection in the part (likely to the point it breaks before deflection sets), but not flex the part in the first place.

@InheritanceMachining

10 ай бұрын

Shorter is a good idea! I also don't even really need the slot adjustability so a simple co-bored hole would work as well.

From a video production standpoint, a lot of work went into this to give it such a polished look. Very well done.

Man, if you were my shop teacher in high school, I'd be working a whole different trade right now. Amazing video, simple but entertaining editing, and overall chill guy vibes; 10/10 video my friend. Instant like and subscribe.

The expanding dovetail is great. As an ME I'd make these mods. 1. 50% longer dovetail. 2. Square shoulders on the dovetail that rise, say, 3/4" above the surface of the rotary fixture plate. 3. A larger, stiffer cross block with an internal slot that rides on the shoulders of the expanding dovetail thus maintaining the 90 degree angle between the dovetail and the cross block.

You need to patent that, and make a lot of money off of it! It’s utterly brilliant.

Just because it’s now public knowledge shouldn’t keep you from getting a patent. The biggest problem is the cost of the patent. This I know first hand as I’ve patented several motorcycle performance products . I’ve been knocked off by some big boys . One in fact was Harley Davidson. The fact that they even admitted they stole my idea still left me high and dry. I spent a bunch of money securing a utility patent. This is the only patent that really offers you protection. A design patent is virtually useless because a simple 10% change and your out of the game. Now a utility patent protects the idea itself regardless of design changes. While this all is true the BIG problem is how well the patent was applied for and written up. Big boys with deep pockets will have their attorneys pic it apart and most always find something they can use to beat you. Maybe not however but in the process you will spend a small fortune defending your patent. As in the case with HD while they agreed they stole it they replied saying you won’t live long enough to collect. Your patent is only as good as the money you have to defend it. Of course if your fortunate enough to have a perfect attorney your ok. However you will spend serious money in securing that as well. You will then have to basically prove how much money you will loose in sales as a result of this. The other sad part is you need to spend money to renew the patent ( I believe it was every3 or 5 years) bottom line is that you’d better be ready to spend serious money. Hence you really need something that will potentially produce even bigger money. In actuality it’s pretty pathetic that a patent is intended to help out the small guy with not so deep pockets and falls way short of that. Wrong…..simply WRONG.

Suggestions: Instead of one-sided beveled edges, it needs to be two compliant v-grooves either side on the top surface of the lower piece (two bevels each side, effectively, 4 altogether). Then the bottom bracket is forced into the upper block, re-enforcing its width dimension, not pushing the sides apart, and you can then lose the lower compliance cut. The clamp needs to be a cam lever-lock [at least, for a 1st stage compression, to get the clamping forces loaded up before a secondary nip], like on a bicycle seat post, then there is no torque being applied during the clamping action.

My 3D printing philosophy often involves getting things close enough, testing them to failure, then redesigning and running the process again until the failure test is within reason. Also known as "Close enough to perfect"

"If I can measure so much as a thousandth of an inch of variation I won't be pleased." "This is fine. Everything is fine." Sometimes the on the fly change you need in a project is managing your own expectations. Great work man.

Thanks a lot, Brent! Welcome

I do like your brass washer idea to stop the screws from damaging the inside of the slides, but they are made of A2 tool steel, and you learned well that you could also just heat treat harden the slides :) EDIT: as for preventing warping, I wonder if it would make sense also bevel the outside bottom of the slides, make the dovetail nuts slightly wider than the slides and cut 2 full V grooves, one for each side of the slide. That should still allow the movement you want when loose, but greatly limit outward flex when tightening. I’m not sure that would solve the issue of friction though, you still might be able to lock it down slightly out of square. EDIT2: Never mind that’s dumb because that would make the nut stick out farther than the edge of the slide. You would also need to make the slides wider and have a skirt of some sort. It would definitely take way more fiddling than it’s probably worth

this has inspired me to go out of my way and watch another machining video

try replacing the chamfer on each of the litle rails of the guide bars with a V shaped groove, and a matching pair of ridges on the dovetail part (or vice versa). should still be self centering and wear resitant, without pushing the walls outwards.

the precision of this wor, and how you r3ecord it.. awesome job. Got a sub.

...and thanks for the nice Audio! This also needs to be said because it's much appreciated! 😊

As a retired toolmaker I can appreciate the skill involved by you. Nice to see some manual machining and not CNC work.

I love the idea. I would improve it by making the slide bar's bottom chamfers into V guides. kinda like upside down lathe bed. Then add a matching V grooves in the top of the compliant tail. That way when you tighten it, it won't expand the bar. I'm not sure I've put my idea into words too well, but ii hope it makes sense to you :)

I agree. Have the force act in compression on the slide and then deflection in the slide should be negligible. Great video and love the end result.

This was a great idea in which can be used in several trades. As for the fix it just seems that you have to increase the wall thickness

Very good teacher ! you do well at explaining the hows and whys and whats of the processing.... wish i learn first hand from someone like me like u

I think what you need to do on your clamp bars. Put prismatic ways like a lathe has instead of the one sided ones. So the force is balanced when you tighten the clamp screw. You could even have a V way and a flat on the other side like a engine lathes tailstock has. That way there should be no spreading of the bar. I would also make your brass washers square instead of round. Just some ideas. Great video!

And don't get me wrong i have huge respect for the machinists that made really complicated parts bevore cnc existed. I also enjoy manual machining there is something satisfying about grinding your own lathe tools. But once you get used to capeable machines and CNC you hardly ever wan't to go back

A very genius idea I love it! A prototype like this puts you almost to the point of being at the finish line. I belive than even when this is pretty hard to manufacture, I could see this being used in the industry pretty well once perfected. In my opinion, the main deviation comes from the point where the duckt meets the top part, there is too much free space and the top aligning groove needs to be deeper and the tolerance need to be so tight that you would need to use a littlebit of oil just to make it slide considering the tolerances you would be going for (lets say 0,02mm assuming the workplace stays at constant temperature) Some very precise machining will be required tho, especially considering this is toolsteel. Very very theoretically, you could messure the table groove, make a prototype, messure how much does the thing twist at constant tightening NM, then take the messurements, stare at the numbers for 2 days and then calculate how to offset the angles and the dimensions to overcompensate for every single point of deviation and go absolutely perfectly square. Also surface hardness will be a bit of a brainteaser on this one. Idealy you would harden the surface of both the top and bottom part to avoid wear from each other and the rest of the enviroment but the tricky thing is that the bottom needs to stay springy! But then... sometimes is better to just swollow the perfectionism and accept the thought that considering the application - rounding off edges, even the prototype seems like an overkill. The mentioned above would only make sense for if you wanted to use this as a stopper while machining but even then... would it rly be perfectly square.. I hope we will know one day.

Awesome! The details and the way you threw in a scattered joke. Brilliant!

Excellent design and video! While it wouldn't be as convenient as your initial design..... I'm wondering if having two slots rather than the one continuous, (which would leave a bridge for support in the middle) would solve your issue-? You're definitely on the right track!

@@InheritanceMachining it certainly looks like a very useful piece of kit, i'm not very familiar with American measuring units though so i don't know how much you'll be able to use those unique guides you made. and yes there's no better excuse to make something than to be able to use a piece of machinery.

Did you consider ditching the dovetail slide completely, and using a piece of half round stock to directly sit up into the dovetail slot? If so, the top guide could have a small step that nests into the top of the dovetail. Also, I’d keep the guides running parallel to the dovetail slots. KISS. I can send you a pic if you want. Also, your mill is not round on every side, so bumping the guide to it could introduce an error (unless the guides were very tall).

Thanks, Chris (got the drawing) My only concern with that method is that there has to be some amount of clearance in that step and that will only increase with time and wear. But honestly could probably still work better than mine came out. You did just remind me about how some mills have progressive flute radii though. I completely forgot about that. If i remember correctly that came about to prevent harmonics from forming while running CNC.

@@InheritanceMachining yes, but in reality, you only need the guide to register on one side of the dovetail (the far side) but I understand your concern. If the guides are long enough (maybe half the diameter of the plate), then it would take a ton of use before anything wears. Specially if made of something harder than the plate.

I like the idea but I believe the problem is the slit inside the bottom dovetail piece, which functionally widens as it tightens; this also widens the top bar price. Not sure if that tapered washer idea would be able to counter those widening forces.

I​​f you made them from A2, then hardened it all, it might. You could also try a rectangular nut, instead of round, to increase contact & resistance to spread. Then go w/ a square cut & slot instead of a taper. Another thought, rather than merely going beefier w/ the top block, would be to make it 1 sided w/ a ridge back on the other a la a long, cast iron precision straight edge. Then make the other side slightly beefier.
