¡Gracias a quienes me ayudan a corregir mis errores de inglés!

Yo necesitaba una prensa de mano (sargento), pero grandecita. Cuando fui a ver los precios, me dije "mejor la hago yo". Acá les muestro cómo la hice, con muy poco dinero. Compré por unos 5 U$S unos trozos de hierro T de 1 pulgada x 1/8, de los cuales me sobró una tercera parte. Los demás elementos los tenía en casa. O sea que a grandes rasgos podría estimar en 3 U$S el costo de la prensa de mano.

Thanks to those who help me to correct my English mistakes!

I needed a hand press, but a bit one. When I went to see the prices, I said 'better that I do it myself". Here I show how I did it with very little money. I bought some T iron pieces of 1 inch x 1/8 for $5USD, of which about a third is extra. I had the other elements at home. So I estimate the cost at roughly $3USD for the clamp.

Step 1: La base (the base)

Decidí que mi prensa tendría una profundidad de garganta de unos 15 cm, y de acuerdo a eso hice un corte en uno de los trozos de hierro T, sin llegar a separar totalmente la parte cortada. La doblé en ángulo recto y reforcé con soldadura la articulación. Luego corté un trocito trapezoidal de varilla de 1/2 pulgada x 1/8 y lo soldé entre las dos partes de la nervadura que quedaron separadas.

I decided that my clamp would have a throat depth of about 15 cm (~6 inches), and according to that I cut one rib of the iron T. Then bent it at right angle and reinforced the joint with a weld bead. Then I cut a trapezoidal piece of steel 1/2 inch x 1/8 and welded that between the two sides of the ribs that were separated.


<p>Not sure how I missed this when you originally posted it. I make it a practice to read all your instructables. I don't know if you are still a member and will see this, but this is really nice. When I saw the first photo I thought he is going to show us a trick on using a clamp in a new way. When I realized this was the clamp you built and not bought I was impressed.</p>
ya hice seis con mi ayudante. a el le encantaron.
Yo tambi&eacute;n hice otras, pero m&aacute;s chicas. Tuve problemas con algunas que ten&iacute;an las mordazas muy cortas, alrededor de 5 cm, porque resbalaban al apretarlas. Entonces les hice con la amoladora unas peque&ntilde;as muescas transversales a lo largo del borde de la barra m&aacute;s larga, separadas uno o dos mm entre s&iacute;, y con eso se arreglaron. <br><br>En vez del mango c&oacute;nico les puse arandelas soldadas, m&aacute;s f&aacute;ciles de conseguir y de poner.
me hice dos don schiavone! son mis mas practicos sargentoss
Me alegro de que la idea te haya sido &uacute;til. Yo hace poco me hice 5 m&aacute;s, un poco m&aacute;s chicos. No s&eacute; cu&aacute;l es la cantidad de sargentos necesaria, porque SIEMPRE HACEN FALTA M&Aacute;S.
Que bien quedo su sargento yo dabrique uno parecido pero el mio no es corredizo sino que tiene unas perforaciones cada 10cm para fijarlo con un perno con chaveta ,el ajuste lo da el tornillo de la prensa de 15 cm despues posteare un instructable para que lo vea Saludos
Gracias por el comentario. soul_eater. Espero ver pronto tu instructable.<br><br>Thanks for your comment, soul_eater. I hope to see soon your instructable.
Muy buen instructable y muy bueno qued&oacute; el sargento! Como te dijo un muchacho m&aacute;s arriba, venden tuercas largas, eso te va a ahorrar el dolor de cabeza de la desalineaci&oacute;n de las tuercas al soldarlas! (las venden en cualquier buloner&iacute;a o ferreter&iacute;a no muy chica). Eso s&iacute;, antes de soldarlas sacale muy bien el galvanizado, me lo vas a agradecer (si ya intentaste soldar algo galvanizado, me vas a entender!).<br> Tambi&eacute;n en la parte de la varilla roscada donde va la arandela, seguro te va a ser m&aacute;s f&aacute;cil para remacharla hacerle un huequito primero con una mecha (un poquito nom&aacute;s alcanza). Tambi&eacute;n pod&eacute;s probar remacharla con un punto de marcar o algo parecido.<br> Me parece que ahora me voy a hacer un par yo pero chiquitas que no tengo ninguna en casa.<br> <br> Saludos!
Gracias por el dato! Qu&eacute; lindas esas tuercas largas, voy a ponerme en campa&ntilde;a, pero tal vez las consiga en La Plata, porque ac&aacute; en Villa Elisa, gracias sin consigo de las comunes. <br><br>Hice un par de sagentitos un poco m&aacute;s chicos, se los regal&eacute; a mi hijo para su cumplea&ntilde;os. Si me acuerdo cuando lo visite, les voy a sacar una foto para agregarla al instructable.<br><br>Thanks for the tip! Nice these long nuts, I will try to get them, but maybe in La Plata, because here in Villa Elisa, thanks if I get the ordinary.<br><br>I made ​​a couple of littler presses, gave them to my son for his birthday. If I remember when I visit, I will take a picture to add to the instructable.<br>
Excellent Idea! Very well described in fine detail.
It looks very good. I had not thought of making one of these, but may one day. The pintle you used to improve the threads after welding is called a tap, or perhaps a thread chaser.
Thanks Phil, I fixed it.
Don Osvaldo usted realmente posee un gran ingenio, realmente el instructivo es muy claro y no se diga de la gran utilidad de estas prensas para aquellos que gustamos de hacer cosas en casa. Mis felicitaciones y agradecimiento por compartir sus conocimientos
Gracias por tus amables palabras, balddemon. Yo que t&uacute;, reservar&iacute;a el &quot;Don&quot; para alguien m&aacute;s importante... ;) Eres muy amable.
Excellent work. <br> <br>This looks like a great project for my welding students. <br> <br>For step 3: <br>There is something called a coupling nut, it is a long nut (about one inch) that is used to join two pieces of threaded rod. You can find them in any hardware store (or big homely orange or lowly blue) for less than a dollar. It would replace the three welded nuts and you would not need to rethread it when you were done. <br> <br>Thanks again for a great idea! <br> <br>Mikey <br>
Thanks for the idea, I did not know of the existence of these nuts. Surely this project is ideal for beginners, I am one of them.<br>And thanks for the comment, too!
Well done :-)<br><br>In step three.... to help avoid the warping when welding on the nut, tack weld all 6 corners of each nut to the next nut, before tying onto the slide body for welding. <br>If the threaded rod is STILL tight, once the welding is done, because of misalignment, run another small weld bead on the outside of the nut assembly. this should pull the threaded hold back into alignment. <br><br><br>Step 4 could use another 4-5 pictures to help explain this CRITICAL step.<br>I'm sure we can all figure it out, but the point is so that we don't HAVE to :-)<br>[sorry, just read the picture note saying you missed taking the pictures]<br><br><br>
I added 4 pictures in step 4.
1) Yes, I am a newcomer in welding, I will consider your suggestion for next time.<br><br>2) I missed to take photos of the process, but I will put two or three of the finished slider. It is simple.<br><br>3) Thanks for your comment.
Nice job!<br /> Having more than one is a good idea and in a few sizes, too!<br /> <br />
Thanks for your kind comment!<br><br>Surely I will do another/s.
I always like the simple things you make!
Thanks for your kind comment!
Indeed, it is very beautiful - and well deserving of paint. I'd trust it more than most of the pound shop (dollar store) efforts. Thanks for the 'ible.
Thanks for your kind comment, karlpinturr!
