Small Toolmakers Clamp

Small Toolmakers Clamp

Find the large one here!

I designed this little toolmakers clamp for light clamping work such as glue ups. Obviously its not designed for actual machining work but its quite strong for a printed clamp!

Hardware you need:

• 2 x 60-70mm of M4 allthread/threaded rod
• 2 x M4 threaded inserts
• 2 x M4 washer
• 3 x M4 nuts
• Superglue or loctite

Instructions:

1. Use your soldering-iron to melt in the M4 threaded inserts. Alternatively you can press them in with a vice. Make sure they go in straight!
2. Carefully glue one of the M4 nuts into the smaller knob. Make sure not to use to much glue. Afterwards use glue or loctite to fix a length of threaded rod in the knob and nut. Again make sure to avoid glue squeezing out.
3. Thread the assembly through the rear insert in the jaw. Then glue another nut and washer on the end of the rod, so that ~5mm of threaded rod stick out. (See pictures!)
4. Now insert the last nut into the taller knob, again with just a little bit of glue so that no glue squeezes out. Make sure the nut goes all the way in. 
5. Now you need to be really careful: put a little glue on the inner threads of the nut, making sure no glue lands on the face of the nut. Hold the knob into the undercut on the second jaw with the last washer inbetween. Then quickly screw the second threaded rot throug the jaw into the knob, making sure you get it all the way in, before the glue dries.(See pictures!)
6. Now for the final assembly just screw the middle threaded rod into the middle insert in the other jaw. (See pictures!)

Have fun printing!
