PaulKrzysz Posted December 17, 2015 Share Posted December 17, 2015 Hello Everyone, I'm currently making a 400lb anvil. The main body is made of multiple layers of stacked 1''x3'' Flat Bar. It will be 17'' tall, 4.5'' wide at the face, and 40'' long. I will hardface the top I am making a video series of the process. Here is the first part.https://www.youtube.com/watch?v=YYr-gQwQ_3Q Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 17, 2015 Share Posted December 17, 2015 Are you putting the pieces vertically or horizontally? Link to comment Share on other sites More sharing options...

Crazy Ivan Posted December 18, 2015 Share Posted December 18, 2015 I had the same fears as Thomas. As you probably know, if the bars were stacked flat you would have a 400 lb anvil entirely delamated through and through. You probably wont have that problem with the bars vertical. Let us know how it turns out! Link to comment Share on other sites More sharing options...
PaulKrzysz Posted December 18, 2015 Author Share Posted December 18, 2015 The bars I used were 16'' long (or tall). I did add one bar horizontally along the bottom to raise the height to 17'', depending on what scrap is available after i make the horns and supports, I will add more horizontal bars along to bottom to raise the height. I don't think adding flat bar to the bottom of the 16'' long vertical section makes it worst then if they were not there. At worst it adds mass that would otherwise not be there.

Everything Mac Posted December 18, 2015 Share Posted December 18, 2015 Quite an ambitious project there Paul. Looks good to me so far. What is the weight of the block you have at the end of the first video? Cheers Andy Link to comment Share on other sites More sharing options...
PaulKrzysz Posted December 18, 2015 Author Share Posted December 18, 2015 It currently weights around 275lbs. I have the two side pieces which will receive the horns welded on. This is what it looks like now. The 6'' squares are there for reference. Link to comment Share on other sites More sharing options...
Everything Mac Posted December 18, 2015 Share Posted December 18, 2015 Cool. I'm sure it will look decent when it's finished. Are you putting an upsetting block on there? Cheers Link to comment Share on other sites More sharing options...

dfsrusa Posted December 20, 2015 Share Posted December 20, 2015 Very nice. Can you educate me on what delamated means and why that would be bad. I'm guessing there would not be good rebound in it, but the internet and this site didn't help me. Thanks Link to comment Share on other sites More sharing options...
Everything Mac Posted December 20, 2015 Share Posted December 20, 2015 Hi dfsrusa, welcome to the site. Delaminating is where layers of a material (laminations) come away from each other. Imagine a stack of wooden boards sitting on top of each other. If you were to hit that with a hammer the energy wouldn't travel very effectively through them and the loose boards would be likely to separate and peel away from each other. This is delamination. Stacking the steel flat on top of each other, even welding it together at the sides doesn't produce a strong block. Like the wood it won't transfer energy very well and will likely split over time. Stacking the steel vertically means energy can travel down through its length making for a better tool. Imagine a cardboard tube, lying horizontally it wouldn't take much to flatten it, but flip it up vertically it is much stronger.

dfsrusa Posted December 21, 2015 Share Posted December 21, 2015 Paul, in your other videos where you have a plate with different sized holes to secure rivets in, how thick is the plate, and can it be mild steel? Link to comment Share on other sites More sharing options...

The thickness depends on the diameter of the rivet material. The rivet head should be x1.5 the diameter of the shank, and so should the bolster. Yes you can use mild steel.

Thanks That is what happens to your wife's hardwood chair from the breakfast nook when you forget to take in from the back porch and it rains. The oak slats start to separate. This caused de-lamination of you and your wife's good graces. The two start to separate in her mind and you need to act VERY fast to re-glue your self in to her good graces. You see it mostly on plywood outside. Link to comment Share on other sites More sharing options...
Comansa Posted August 1, 2016 Share Posted August 1, 2016 Hello everyone,I'm new to working with steel and want to make an anvil. The material I have is a sheet of steel that's 3 1/2" thick 8" wide and 25" long, I also have a 20 1/2" x 17 1/2" x 1 1/2" plate and two 9"x 9" x 2" plate and a lot of 3/4" x 3" flat bar for filler where needed. The horn I want to use 3 1/2" round bar stock i have and use plate steel around the bar stock and neck it down to make the horn., I have 12' of the 3 1/2" bar stock. And some other plate steel I've been collecting for a long time.my first attempt I'm wanting to mak at least a 500lb anvil providing I have the right material. Just gathering idea's and instruction, I don't want to waste time or material. Thank ya'll for any help. Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 1, 2016 Share Posted August 1, 2016 You do realize that to do it properly you will need to do full penetration welds between every piece and so it will end up costing more than buying one right? I would suggest doing a modified Italian style anvil with a large center chunk and added horn and heel and feet. Link to comment Share on other sites More sharing options...
Comansa Posted August 1, 2016 Share Posted August 1, 2016 No fun in buying one. I want to make it from the materials I have. Plus as you can tell I need the practice welding. Link to comment Share on other sites More sharing options...
SLAG Posted August 1, 2016 Share Posted August 1, 2016 A 400 pound anvil should do a quick job of sucking the heat out of a forged chunk of heated iron or steel. That size anvil makes sense if your power hammer is large, and you, ideally, have a striker or two, and the cost of forge fuel is not an issue. Just cogitating and saying. SLAG.

ThomasPowers Posted August 1, 2016 Share Posted August 1, 2016 No problem and bragging rights to boot! Ernie's made a few and posted his methods at: http://www.metalwebnews.com/howto/anvil1/anvil2.html Hey most of us have anvil envy; my 410# anvil is my backup for if my large anvil isn't available...
