Greetings to all those who like to tinker, I propose for consideration the instructions for making a powerful vise with large lips. The vice is clamped by two threaded shafts at once, which increases their reliability, and also increases the maximum possible compression force. The shafts are driven synchronously by a chain drive. Everything is assembled is not difficult, but the author turned many details on a lathe. It is especially convenient to clamp pipes with such a vice for further cutting. If you are interested in homemade , I suggest you study it in more detail!
List of materials:
– square and round pipes;
– two stars and a chain;
– threaded rod (made of good metal);
– nuts ;
– rectangular steel parts (for lips);
– steel plates;
– round timber for turning work;
– thrust bearings.
List of tools: < br> – lathe;
– drilling machine;
– welding machine;
– tape measure, marker.
The process of making homemade products:
Step one. Making guides
Making guides, take a square tube and weld one side with a thick steel plate. Then you need to drill holes in the plates.
The author cuts the other ends of the pipes at an angle.
Step two. “Traction” axles
We cut off two pieces of a round pipe, weld the stop to one end, the author turned this stop on a lathe. The stop will abut against the guide, for this axis and will pull the threaded rod when tightening the vice.
Well, at the other end of the pipe, turned nuts are pressed in and everything is well boiled.
Step three. Sprockets and Lever
For sprockets you need to grind flanges on a lathe. These flanges will abut against thrust bearings, the author made the clips for them himself, or you can buy ready-made ones.
In the end, the sprockets are welded to the flanges, and the flanges will rotate the threaded shafts.
We also grind a lever out of a round timber or hairpin, steel must be chosen stronger, otherwise the lever will bend. We put nuts on the ends and weld them.
Step four. Moving lip guides
Cut out two pieces of pipe that will go into the “body” of the vice. On both pipes, the author made weld surfacing, grinding the excess, as a result, the gap became minimal.
Flanges with threaded shafts and sprockets can then be fastened to the pipes.
Step five. Making lips and welding a vice
We make lips from a steel bar or rectangular parts. We make notches on the lips with a grinder so that they firmly grip the material.
The lips are securely welded to the guides (pipes). Be sure to cut out and weld the stops, thanks to which the lips will be securely fixed in the vice and will not rip out of them under load.
In the end, after careful adjustment, we weld the vice.
Step six. Protective shield
Above the stars we make a protective shield. It is necessary so that your sleeve does not get pulled into the chain during use, and so on. The shield can be made of thin sheet metal, we fix it with screws or self-tapping screws.
Step seven. Painting and assembly
The author wiped the metal with a degreaser, then applied primer and painted it. The vise can be assembled, thrust bearings, threaded rods and other friction units are lubricated with thick grease.
The vise can be assembled, everything works fine, the vice perfectly grips pipes, as well as large objects.
This completes the project, I hope you liked the homemade product and found useful thoughts for yourself. Good luck and creative inspiration if you decide to repeat this. Don't forget to share your ideas and homemade products with us!
