I Might Have Invented Something New...

So the rotary fixture plate is done, right? WRONG. I’ve got just one more feature to add to it. A set of material squaring guides. I have an idea for a dovetail clamp that allows for adjustability, but is also self-squaring. I’ve never seen anything quite like it which could either be a good thing or a bad thing. It’s one of those weird things where the mechanism makes sense, but at the same time… doesn’t. So let’s find out, and build a functional prototype!

[@younghan3573]

Could you heat treat it to strengthen the sides?

[@therhea8003]

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.

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.

[@RiversJ]

You could have it as a walked key for the bolt, and have a spring loaded Alan key inside it, be a bit finicky to build but it should work.

[@brbarsonelk]

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!

[@smallsee]

Just thickening the sides quite alot could stop bowing and also provide much more surface area for friction to hold it square.

[@cwell2112]

I don't think heat treating would help with the flexing issue. The parts are deforming elastically and the amount of deflection is controlled by Young's modulus - a value that doesn't change with heat treatment.

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]

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

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.

I was thinking the same thing. No real reason for there to be adjustment in that direction since that clearance for an end mill doesn't change at all between big and small corner rounds

[@alphamurphy5712]

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]

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]

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. Hardness would help with the friction but wont effect the elasticity as Malex mentioned. I'm hesitant to make them wider just because it takes up clamping real estate. Thanks for the ideas!

[@joojaa3927]

Try to turing the v groove 90 degrees, thisway the bulging is more prominent on one axis. Or make the contact a point contact... Anyway a alternative would be to have pins for alignment instead of the groove then you dont have lateral forces. Anyway this is super nifty stuff.

[@FreeOfFantasy]

@@InheritanceMachining If you were to make them considerable wider then they are and drop the slot you could replace the dovetail making them square to the nut with pins. That way you it wouldn't expand anymore. You could also have the bar not touch the face of the plate and lock only with the expanding dovetail. That way friction from that contact would not keep the bar from aligning.

[@josebarreto1115]

I'm no engineer, but how about an L profile where the larger side has the screw offset, and the shorter side touches against your part?

[@squirreltamer2548]

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

[@arnoutdecock476]

Unfortunately, by making this video he's no longer able to patent it.. it is now public knowledge.

[@Lwimmermastermetalart]

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.

[@McStebb]

@@arnoutdecock476 Not true. If someone else tries to patent this before him, he could bring this video forward as "Prior Art". His idea is perfectly safe. In fact, the video serves as proof of its origination.

@@InheritanceMachining I"ve got to agree with Johan on this one, I know that were I to get into machining, that I would definitely find this to be an excellent kit to purchase and produce because not only does it have so many opportunities to practicing machining skills, but at the end of the project it becomes an amazing tool that will serve for many years to come!

Nothing more fun than creating shop jigs just to see how they work. Or don’t. How many Friday/Saturday nights I’ve spent in the wood shop making a solution for a one off problem, only to put the jig away in the cabinet then instantly forget what I made it for!

45 years ago I help out a small printing firm, they still printed using individual printing letters. When the page was complete they would lock the letters into a frame and squeeze things up so everything was held tight. To do that they used quoins which are very similar to your clamps. I hope you get the deformation problem solved. Great post anyway. 👍

I probably would have gone my whole life not knowing about quoins. They look pretty nifty. So much technology is being forgotten.

[@thepagan5432]

[@Mordredofthemoor]

I went from knowing practically nothing about precision machining to knowing a little, this was a surprisingly engaging video :)

[@ChrisMacdonald-ns8rx]

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.

[@Nickle314]

Or two screws, with expanding dovetails

Just discovered your channel. Great camera work and narration. I could watch these kinds of videos for hours.

[@MacDaddy5]

I take a lot of these same approaches when designing something to 3d print. Such a satisfying feeling to create something that came as an abstract idea and turn it into a functional piece

[@weakmindedidiot]

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"

[@aycfes2891]

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.

I'm not a machinist at all. I've never even attempted anything related, but I am an admirer of the kind of skill and passion it takes to become proficient at it.

[@brianm744]

Recent subber here. I'm not a machinist but I do enjoy watching the precision and accuracy that you utilize to create the things you do. One thing my Dad taught me was this: You only learn to do better from your mistakes, not your successes. Good luck making further mistakes and learning from them.

[@EdgePrecision]

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!

[@InheritanceMachining]

I literally just had this idea as well! Just like the lathe ways like you said. Thanks for the validation!

You can make the washers have a taper that fit into a grove inside the bars. The washers would pull the bar sides in to the washer width instead of pushing out.

[@evanharriman5352]

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.

[@georgedennison3338]

​@@evanharriman5352 Not seeing how the spread in the dove tail piece causes spread in the top piece. I'm thinking it's the clamping force doing it. 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.

[@johnsherborne3245]

Adding a shaped slider rather than the washer would be rather elegant as long as it didn’t contribute any side ways forces, I’m sure I’ve seen something that did just this, just can’t remember where. Nuts!

This is a great idea, only problem is that the point of contact will always be in line with the dovetail slot, so small parts can't be held.

they are working as intended Brandon, once youve set the stop they are doing the job. another way if you want it to be more square to the work is put a center punch in the stock and dead center in the mill to hold it in position and then bring the stops to the piece.

[@InheritanceMachining]

Oh that's pretty clever... i had a similar through for any parts that do take a centering pin, a guide on 1 side would square it up very easily
