Motor Clamp

I am extremely close to finishing Grathio's Secret Knock Detecting Door Lock ( I am about to mount to my door, but unfortunately the clamp (step 3) has not been working out for me, and in no way will the motor be strong enough to turn the lock. Any other suggestions on how to hook up the motor to the door? FYI: my casing is entirely different from that of his instructions. Thank you!

I need a special tool ? Answered

Has anyone any suggestions for a tool which would be "like" a camera iris, with a hole several mm long, but which can be varied in diameter from 1 (0.040 ") to 0.2mm (0.008"). I need to set the diameter fairly carefully, to just gently pinch a bundle of 70micron (0.0029"") optical fibres passed down the centre. The hole needs to be very circular and rigid, even as its closing...... Something kind of like the mechanism of a "pin-chuck" suggests itself, but wouldn't be very round in the limit. Any ideas ?

How to fix Bar Clamps that Slip?

My grandparents are moving, and are organizing stuff... I just found an antique bar clamp (An ELZETT, a bit smaller than that one though). The sliding arm/jaw wouldn't slide on the bar, so I removed the rust. The sliding jaw wouldn't lock onto the bar when I tightened it. I tried enlarging the grooves/notches that were on the bar with a hacksaw, but that didn't really help.  Does anyone have an idea for making it lock/catch on the bar? My grandpa might have several more of these clamps! Drilling holes into the bar and adding a removable pin - no, because this steel is really hard and I'd go through 10 drill bits. The only thing I can think of is to take it apart, and use the hardware for a homemade wooden clamp. But I think it would be easier to start from scratch... I really want to fix this clamp! The quality of old tools, throat depth of this clamp, the screw, the swiveling pad - I need these! Thanks!

Help finding adjustable and slip resistant material!

I am working on a project where I want to be able to paint with 5 brushes of different sizes simultaneously. For this, I need to build a device that can hold 5 paintbrushes together, one next to another with a 0.5 inch gap between them (so the bristles don't overlap). My challenge so far is to find a clamp or material that can adjust to various sizes of handles while keeping everything still when I push down to paint.  I have tried to poke the brushes through a piece of foam but they will slip and go through (depending on the shape of the brush). Someone suggested duct tape but I'd like this device to be reusable and easy to change between brushes.  Basically, can anyone suggest an adjustable clamp or some better material that can fit various diameters and hold still?

Anyone have any clue what this tool was used for or what it is called?  It was found in the dirt on a farm.  I will attempt to describe as best as I can hoping that this will help after you see the pictures.  It looks like the main piece is like a large needle with an eye at the one end and a point at the other.  Then there is a curved hook sideways to the main piece (see the shadow on my leg).  The hole/open portion in the middle appears to be some sort of clamp.  When you press on the tab piece that is closer to the eye, the hole opens up, releases the pressure on whatever may be inside the hole.

What is Polyurethane Construction Adhesive? (DIY Clamp Question)?

I'm building a wooden clamp, and I've seen people use Polyurethane Construction Adhesive, and I don't know exactly what it is. Of course it's an adhesive, but I can't seem to find the properties that define it... I also know that it's really expensive, and has a very short shelf life, so I want to maximize my use out of it, if I buy it. Is it sticky, before and when cured? When cured, is it brittle like super glue? Hard like epoxy? Fairly soft like Hot-Glue, or very soft like silicone adhesive? Does it adhere better than most epoxies to wood metal? Do you think it could glue a threaded to rod to a wooden handle strong enough on a homemade clamp? Is it the expanding glue? Do most types stink like crazy? (worse than most Epoxies) Do you think it is worth the price? Is it that much better than Epoxy? Thanks!

What do you recommend for wire connectors / clamps for making a Nitinol shape-setting fixture?

I'm weaving Nitinol wire so I have a square piece of plywood with the shape that I'm weaving around placed in the center and the bundle of .7mm Nitinol wire is emanating also from the center.  For clamps I used speaker posts that have hand-rotatable post "screw-collars" and are gold-plated.  However they're really hard to work with and to mount.  They're great because they also have a high-current screw-in wire junction in the back.   Anyway, what alternatives can you think of while requiring a hand-turnable release and clamp of the Nitinol wires (so plain terminal blocks won't work unless you also found a screw with a handle that fits).  There will be about 20-100 small wires used in the bundle to weave the shape.  And the board is about 30cm sq. at the moment so more likely there will be only 20, in order to fit the wire clamps unless you know of a micro method, such as: copper tubes and "nails", which might work now that I think of it...
