The abrasive is an attempt to compensate for the wrong curve on your cam. The whole point of a cam is to have an apex that turns just slightly past the perpendicular line from the clamping surface to the pin center. To make an effective cam, select two circle diameters who's difference equal the maximum amount of deflection and pressure you wish to achieve with your clamp. The small diameter will just barely contact the clamp while the larger diameter represents the plateau you will reach to clamp. You can either continue the larger diameter the rest of the way around the cam, so that you can swing the arm to any position after the clamp point, if you think this might give you a potential clearance for some other reason, or you can end the cam with a flat section to stop it from continuing. The problem with a flat, is that it acts as an extreme cam that could allow someone who doesn't understand the concept, to pick up your clamp and break the jaw off of it, despite your reinforcement pin. I would also like to suggest using a screw instead of a pin for the reinforcement, as it actually grips the grain to prevent splitting. I suggest a countersunk screw with the head left on, so that if your clamp is broken, you can glue on a new jaw, instead of starting from scratch because you can't extract the blind screw you sawed off to achieve the purist look. The abrasive is going to wear your clamp out faster than you are going to want, and the abrasive will also quickly clog, reducing the friction that is compensating for the improper cam design. Look at your commercial clamps. They don't have anywhere NEAR the deflection you have on yours. You're just begging to break that jaw off, and never need that much pressure for this type of clamp. Cam clamps are for gluing and do not require much pressure. If you need more pressure, your parts to be glued aren't properly formed and fitted. I'm going to watch someone else' video now and see if I can't harass them about something. Thanks for the video. Love the paisley camp clams! I wonder who's gonna notice the spelling poke I threw in here...

Also you can make the channel which the metal bar runs through the head at a 2-5 degree angle towards the cam to help the clamp not go out of parallel under pressure. Just like a traditional bench dog.

I may have to make another video using that method.. I did consider doing it that way but opted for solid construction in the end.. I do need a number of small cam clamps for finer work come to think of it.. There's a very easy fix if the sandpaper does start eating away the wood.. just glue another piece on the opposite face.. the fine tuning option really does greatly improve them for me.

Excellent tutorial! I have another method for building cam clamps in which I use 3 plies of wood to make the jaws. The center ply is cut to accommodate the bar and cam. This way I don't have to route out the cam slot. This also insures the openings are centered. If the bar is thinner than the cam, small filler pieces can be glued in place to make the bar slot narrower. I concur with Woodeso... the sandpaper will wear away the wood in short time. Cam clamps are not meant to be adjustable.

I applaud your efforts in making and sharing this. There are many ways to approach making cam clamps, but, unless they are made with relatively high precision, their action will be sloppy and their effectiveness compromised. For example, when the cam is thrown, the two jaws must be parallel, not as shown at 21:21. If not, they don't work well on thin materials - the ends of the jaws contact each other prior to the cam exerting any pressure- and will tend to pull the piece being clamped as the cam is thrown. Keeping the jaws parallel is achieved by the fit of the metal bar in the jaws' slots and the pins that hold/position the metal bar. Also, the eccentric hole in the cam should be vertically aligned with the point of contact of the cam in its slot, allowing infinite control over the amount of pressure exerted, eliminating the need for gluing sandpaper to the cam. If not, most of the progressive cam action is lost, making the cam "on/off", as described, and requiring greater friction (e.g. sandpaper) to prevent the cam from slipping. A simple wood screw, instead of the glued-in metal dowel, is sufficient to prevent splitting of the "tongue" at the end of the saw cut. There are other design consideration too lengthy to mention herein.
@CrimsonCustomGuitars

probably a good idea, if I had thought about it beforehand I would have at least rough sanded the edges of the cam.. still, the sandpaper (though an after-thought) really made a big difference to the operation. They worked alright without it though so it really is just an optional upgrade.. :)

to fix the situation of making the grove for the cam there are two other options to routing it out. 1st option used the tablesaw. Set the blade height as the same as the router bit height. and push your wood into the blade and stop the wood to the desired lenght of cut. the blade will naturally give you a curve for the cam to rest in. this is because the blade is round. the next option is to chisel it out after making some relief cuts exactly down the edge of the lengt of cut desired for the cam. basically you are rip cutting a angle. then chisel out the angle and shape the curve in. There is no reason to cut off the wood and re-glue wood back on. I hope that this added a much better solution to the aid of the cam dado.
@givemeajackson
11 жыл бұрын
if you'd push it on, the cam would simply be pushed back due to the direction of the force and the location of the nail it's rotating on. the direction of the pressure has to be lined up with the nail, otherwise the cam would just flex back.

i would have the cam lever be perpendicular to the jaw in its non-pressure setting, and point to the bar when it is clamped. that seems to allow the user to apply more pressure to set the cam. the down side to that is it would be harder to release the pressure. i suppose that answers my question as to why they are typicaly the way they are now. i'd be tempted to make a couple in the reverse pattern to experiment.

Several times while you belted in nails & "rivets" I fully expected the timber to split. The final product would benefit from dressing the end s so they match rather better.

You are right, I feel safe enough taking very little material away but I've added the following annotation on the video.. thanks for the warning! THIS IS A DANGEROUS PROCESS! If you try and remove too much material you could lose control of the wood and seriosuly hurt yourself!! An extra stop at the back of the router would help make this safer but still you must take it slow. If you aren't confident use another method.. chisels, hand saws, circular or table saws all offer alternative methods.

Hi, is there a follow-up video to this? I'm curious about that aluminum pin you placed and glued. The screw on commercially available cam clamp prevents the wood from splitting all the way when you turn the cam. The wide head of the screw holds down the material and the threads keep it from pulling off. The smooth cylindrical shape of the aluminum coupled with brittle cna glue doesn't seem very useful, but if you got it to work I would love to see it. As other commenters have mentioned, the sand paper would eventually wear out the part it rubs against or would gum up. Did this affect the function of your clamps at all or do they work as well as you had hoped? There are tried and tested ways of doing things but it is also good to try new methods to see if you can do better. Thanks for sharing your experiment.

I see this has been around for a long time, but I only saw it recently. This is a message from a fellow South African who doesn't like to see South Africans making Pratts of themselves, - your cam is badly designed. You don't need to glue sandpaper onto the cam, you need to design the cam in such a way that the cam always makes contact at the intersection of a perpendicular line from the pressure surface to the cam pin. In that way, there will be no force that can alter the position of the cam that you select.Your sandpaper is going to destroy the pressure surface of your clamp quite quickly.

As always, it is a joy to watch you work. Craftsmen of all categories have always amazed me, but your precision makes your work especially interesting. Just an observation: Would it be as good (or perhaps better) to use a thin piece of split leather (instead of sand paper), to snug the cam down? I'm wondering if the sand paper might grind down the adjacent wood in time...? Also, what is the measurement of clearance between the steel and wood (where the clamp slides and locks)? (3-4 mm?)
