BarryC Posted May 12, 2011 Share Posted May 12, 2011 Can you guys show me some pics of what types of clamps you are using to hold pieces down on your anvils? I would like to make a few tools that require splitting, and/or punching holes in and my wife doesn't want to be anywhere near a hot piece of steel while I have a hammer in my hands. I did try making a hold down from a piece of mild steel that goes into the hardy and you tap down to make it hold but it didn't work as well as I had hoped. Thanks in advance for the pics!

BarryC Posted May 12, 2011 Author Share Posted May 12, 2011 thanks mb! Looks like you just cut off one leg of the vise grip. Simple and easy. I like it! Quote Link to comment Share on other sites More sharing options...
macbruce Posted May 12, 2011 Share Posted May 12, 2011 I saw this in Hammers Blow ages ago...............A set made with a V on the end would hold down rounds as well................ Quote Link to comment Share on other sites More sharing options...
pkrankow Posted May 12, 2011 Share Posted May 12, 2011 That almost makes me want to abuse a set of those vise grips... Phil Quote Link to comment Share on other sites More sharing options...
pkrankow Posted May 12, 2011 Share Posted May 12, 2011 This seems to be a try it before modifying situation. I took a vise grip clamp and hooked it under the hardy hole. With a little adjustment it started holding solid. Might bit more fiddly than having it fitted to the hardy hole, but no tool modification required.

Marksnagel Posted May 12, 2011 Share Posted May 12, 2011 Hey Barry, At BP's this last tuesday Glenn presented us with two different holddowns. I thought the second one was more to my liking as you could step on the bar and add more pressure to the piece you were working on. I currently have one that goes into the pritchel hole and wedges down on the piece but that can and does work loose. The second BP prevents it from coming loose and frees up your hands to hold the hammer and a tool. http://www.iforgeiron.com/page/index.html/_/blueprints/bp0457-hold-down-r688 http://www.iforgeiron.com/page/index.html/_/blueprints/bp0469-hold-downs-r700 Mark<>< Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted May 12, 2011 Share Posted May 12, 2011 I just use a drive chain hooked to a staple on the far side of my anvil and draped over the anvil and my 3" X 5" angle iron cutting plate. Some guys fit a foot pedal on the near end of their chain to add pressure, but I've not found it needful. My chain is something like a motorcycle drive chain... just farm auction scrap I picked up in a box of miscellany. I made a drive hook mounted on the wall nearby to drape it off the floor when not in use. It usually works well and swiftly. Quote Link to comment Share on other sites More sharing options...
Drewed Posted May 13, 2011 Share Posted May 13, 2011 Wow, I must be doing it wrong! I use something that looks a lot like a bench hold down that a carpenter would use. I set it in the hardy hole and give it a wack with the hammer. IT wedges in and seems to hold just fine. When I need the piece released, I just hit it on the bottom and up it pops. Hit it hard enough and be fast enough and you can grab it out of the air. Looks cool, chicks dig it. However, this is not recommend as the end in contact with the work will get hot enough to burn your finger prints off. Chicks do not dig that.

JNewman Posted May 13, 2011 Share Posted May 13, 2011 When I need a hold down on the anvil I set a work stand up the same height as the anvil plus the work, about 2-3 from the anvil. I then place a piece of square bar (3/4" min)one end on the anvil the other on the stand. I hang a heavy weight from the bar close to the anvil. To use you just have to lift the end of the bar and place it on whatever you are working on. This is really fast to use and doesn't require you to build anything, and seems to hold down as well as anything else. Quote Link to comment Share on other sites More sharing options...
dbrandow Posted May 13, 2011 Share Posted May 13, 2011 I'm just a hobbyist, so take what follows for what its worth, but I did write an article for the Iron Trillium a few months ago on hold downs, here it is: Quote Link to comment Share on other sites More sharing options...
Marksnagel Posted May 13, 2011 Share Posted May 13, 2011 This is really fast to use and doesn't require you to build anything, and seems to hold down as well as anything else. I find that building different tools helps to round out my education. If I never use it, then at least I understand it. Thanks for your idea about the bar and weight. I'll try that too!

BarryC Posted May 13, 2011 Author Share Posted May 13, 2011 Thanks for all the ideas! Mark, I especially like the threaded J bolt. I think I have an eye bolt the size of the pritchel hole and 1/4" plate I can use to make my version! Quote Link to comment Share on other sites More sharing options...
jimbob Posted May 13, 2011 Share Posted May 13, 2011 they make a hold down like the vise grip type for your drill press I have one I had to extend the threaded part to fit my anvil Quote Link to comment Share on other sites More sharing options...
Marksnagel Posted May 13, 2011 Share Posted May 13, 2011 The more I look at the two BP's the more I like the one with the threaded "J" bolt. Less cumbersom I think. I guess i will have to make both and see which one I like the best. Mark<>< Quote Link to comment Share on other sites More sharing options...
KST1-Derek Fultz Posted May 13, 2011 Share Posted May 13, 2011 I don't usually use hold downs. I do it the way it's done over at Purgatory Iron Works: Blacksmith's Third Hand -Derek CAUTION Off site video that is NOT family friendly Quote Link to comment Share on other sites More sharing options...
Old N Rusty Posted May 13, 2011 Share Posted May 13, 2011 Mark, what works for you is the critter. i bent a piece of one inch round to slip into the hardy hole and is long to knock out from the bottom. It bends about four inches off the face 90 deg. and another bend about 3" at a 45 deg to a fattened "foot" to hold work often its weight alone is sufficient to hold for punching or other top tool jobs. a bash locks it tight.I used round bar so it will turn. Or you could fix a chain to a foot pedal to toss over the work, hook quickly on the other side and step on the pedal. this is another use for old trampoline springs,and redneck engineering.

Senft Posted May 13, 2011 Share Posted May 13, 2011 May sound silly, but for a while I've been considering making a pneumatic hold down. Based on personal experience with pneumatic holder-ons used in boiler riveting they apply quick, stay tight and solid and don't rattle off. Something similar on an anvil could be handy. Small tie rod cylinder underneath with foot valve and whatever flavor linkage and style of clamp you want? Also could use small inline regulator to adjust clamping pressure. I dunno but as many times goose necks etc. loosen and fall off at unhandy times I think I might try it. :unsure: Quote Link to comment Share on other sites More sharing options...

Danny, I use the same type holddown in the pritchel now and although it will lock down tight, there are times when it will loosen up while in use. Very aggrivating. I'll also give the chain and foot pedal a try. I'll try them all and then I will be able to tell others what works best for me. Thanks bro.

monty Posted June 3, 2011 Share Posted June 3, 2011 SIve seen a chain anchored to one side of the anvil stand with a weight on the other end which is dropped of the other side of the anvil pulling the chain tight Quote Link to comment Share on other sites More sharing options...

I have a small 2" (bore) x 4" air cylinder that I have been thinking of doing exactly that with. My thoughts were to mount it to my anvil stand and use a rod extension and fulcrum mechanism to work the hold down :) Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted June 8, 2011 Share Posted June 8, 2011 I've seen air brake cans used as hold downs on welding jigs. They only releas wen air is applied. Might be better than an air cylander. Quote Link to comment Share on other sites More sharing options...
