Mudman Posted February 27, 2015 Share Posted February 27, 2015 Very interesting design, I like it. Curious how well the upper portion travels along the shaft. Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted February 27, 2015 Author Share Posted February 27, 2015 put the upper part up and when putting your work in there touch it with the work and it drops straight down on to it Quote Link to comment Share on other sites More sharing options...
VaughnT Posted March 1, 2015 Share Posted March 1, 2015 Neat. Kind of reminds me of the one Hofi showed except you're doesn't have a hinged top arm.How much clearance did you put between the collar on the top arm and the guide rod? Seems like your design would sure help keep the two dies aligned - something that my swing-arm guillotine doesn't like to do at all! Another thing to put on the to-do list.

the iron dwarf Posted March 1, 2015 Author Share Posted March 1, 2015 the minimum clearance I could get from side to side but a lot more the other way so it acts like a gravity hook but when down allows movement as it moves the metal Quote Link to comment Share on other sites More sharing options...
rockstar.esq Posted March 2, 2015 Share Posted March 2, 2015 That's a really good design. Quote Link to comment Share on other sites More sharing options...
Eddie Mullins Posted March 2, 2015 Share Posted March 2, 2015 I like it. I have toyed around with the idea myself, http://www.iforgeiron.com/topic/37579-34slide-arm34-fuller/ . I went back to my guilotine but have project now that need some large fuller, so I can just slip new arms over my stem : ) . Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted March 2, 2015 Author Share Posted March 2, 2015 you need it to rock up and down a bit, I touch the underside of the top bar with the work when putting it in and then the top drops.placing the work close to the upright means you get a > effect depending on how you hit it or near the tips it is more like a < asuming you are looking at it like mine in the pictures.I try to put the work close to the balance point, also between the point of balance and the upright you can use the work to lift the top part up if you want to Quote Link to comment Share on other sites More sharing options...
