I looked at commercial rolling tools and even the cheapest ones, such as the offerings of Harbor Freight, were $80. But they didn&#8217;t have exceptional reviews and they would mar 1\/4&#8243; rod, something that wouldn&#8217;t be tolerated for the art piece I was going to build. So, I decided to build my own.<\/p>\n<p>I had seen several designs online that utilized an ordinary vice, which would cut down on design complexity and cost. I went to work on my own such design, sourcing off-the-shelf components that would be most suitable for the job. Here is the design I came up with:<\/p>\n<p><a href=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/design.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-367 size-full\" src=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/design.jpg\" alt=\"design\" width=\"720\" height=\"409\" srcset=\"https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/design.jpg 720w, https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/design-300x170.jpg 300w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><\/a><\/p>\n<p>The primary components here are:<\/p>\n<ul>\n<li>Two 1.5&#8243; x 1.5&#8243; x 0.125&#8243; angle irons, 4&#8243; long each<\/li>\n<li>Two McGill CFH1 1\/4 cam followers ($6.35 each on sale, Amazon)<\/li>\n<li>One sheave (pulley) 685 lb load capacity, item 5RRX9 from Grainger. ($6.58)<\/li>\n<\/ul>\n<p>The cam followers have a 0.75&#8243; stud, so I picked-up the appropriate hardware for them locally. There is also a steel arm (1\/8&#8243; x ~1&#8243; flat bar) attached to the pulley using two 1\/4&#8243; grade-8 bolts, which I tapped holes in the pulley to accept. The who thing simply bolts to the two inside faces of the vice.<\/p>\n<p>&nbsp;<\/p>\n<p>Some of the pieces:<\/p>\n<p><a href=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/pulley.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-368\" src=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/pulley-1024x576.jpg\" alt=\"pulley\" width=\"680\" height=\"383\" srcset=\"https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/pulley-1024x576.jpg 1024w, https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/pulley-300x169.jpg 300w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>The finished unit:<\/p>\n<p><a href=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/finished.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-369\" src=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/finished.jpg\" alt=\"finished\" width=\"960\" height=\"540\" srcset=\"https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/finished.jpg 960w, https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/finished-300x169.jpg 300w\" sizes=\"auto, (max-width: 960px) 100vw, 960px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>Being put to work:<\/p>\n<p><a href=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/puttowork.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-370\" src=\"http:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/puttowork.jpg\" alt=\"puttowork\" width=\"960\" height=\"540\" srcset=\"https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/puttowork.jpg 960w, https:\/\/nuclearprojects.com\/blog\/wp-content\/uploads\/2015\/11\/puttowork-300x169.jpg 300w\" sizes=\"auto, (max-width: 960px) 100vw, 960px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>The completed art project.

Mineral spirits worked well for me. When rolling, don&#8217;t try to achieve the final radius in a single pass. I found 2 to 3 passes worked well depending on how tight of a radius I wanted and the thickness of the rod I was rolling. Oil on the rod or trying to do too much of a bend at once may\/will cause the pulley to slip.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A project I wanted to do required me to roll some steel rings from round rod of varying thicknesses and diameters.
