downsfish Posted October 10, 2010 Share Posted October 10, 2010 For reasons that I can't quite explain I decided to make the hardy in the anvil I'm building by driving a square drift into a round hole. Eveything was going fine yesterday, I pulled it out of the furnace and got the drift about 40% into (then back out of) the hole without a problem, then ran out of time. Last night I got one of the guys to "help" me, and his "easy" and mine are very different. So while I was tapping it in he went to hitting and before I could say (insert bad words here) it was way too deep, so I turned it over and cooled the end of the drift with air to try to drive it out. That's when I had to go fix something in the Mill which of course explains why the anvil and the drift are now one. It's funnier now then it was last night, and I'm confident that'll continue on. So laugh with me, or even at me and enjoy the pics. Updates to follow :D Quote Link to comment Share on other sites More sharing options...
CurlyGeorge Posted October 10, 2010 Share Posted October 10, 2010 :blink: Now that's a REAL forge!!! Is that an anvil that you are making, or are you trying to work on an anvil that you just wanted to remodel? Quote Link to comment Share on other sites More sharing options...
CurlyGeorge Posted October 10, 2010 Share Posted October 10, 2010 OK. I went back and reread your post. Sorry about that. Duhhh!!!!! B) Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted October 10, 2010 Share Posted October 10, 2010 I'm guessing that you have maybe already tried the brute force option? So now maybe try freezing the drift with refrigerant? Vinegar as a lube / etchant might loosen it? In the old days you could've sprayed it with freon but now maybe something like high pressure air (from divers tanks)? Or maybe CO2? You should have enough mass in the anvil to get a good shrink on the drift without affecting the hole size much I would think. Quote Link to comment Share on other sites More sharing options...
Sam Thompson Posted October 10, 2010 Share Posted October 10, 2010 Is it soft enough to drill out? Quote Link to comment Share on other sites More sharing options...
Ted T Posted October 10, 2010 Share Posted October 10, 2010 I am laughing with ya!! Sharing your experence with us is why I love this place. It keeps it real, and us real. Ted Throckmorton (AKA) Stone Quote Link to comment Share on other sites More sharing options...
downsfish Posted October 11, 2010 Author Share Posted October 11, 2010 Bigfoot: I hadn't really tried to get it out other than at the time, so I'll start with brute force and then move onto whatever else comes next. We've talked about getiing some liquid nitrogen for bushings and such but so far the safety geeks have put the kiebosh on it, so I'll try the CO idea, thanks. Sam: yes it is, but I'm hoping I can find something else first. more to come.... Quote Link to comment Share on other sites More sharing options...
mashin' metal Posted October 11, 2010 Share Posted October 11, 2010 I have no answer other than whats been mentioned, but holy moly you got some serious heat abilities thar' ! Quote Link to comment Share on other sites More sharing options...
downsfish Posted October 11, 2010 Author Share Posted October 11, 2010 Yea the furnace is about 30'x 40', we're pushing out 5 1/2" billets about 28' long. I'm using an inspection door for my anvils which works great unless I get a call. I'm a millwright and as long as everything's running good I can usually get some time to play around, but when it breaks it's GO time. Well I've got it upside down with the drift in a bucket of salty ice-water, I've put a port-a-power on top to drive it out. I figure I'll let it soak for a couple of hours and keep feeding it ice, then I'll hit the anvil with a rosebud and push it right out, sounds easy huh.

double_edge2 Posted October 11, 2010 Share Posted October 11, 2010 could play hang man with it, weld a link for cable or chain to the drift, heat the whole thing to about a dull or so orange, cool the drift, give it a whack then let it drop short on the chain,? weld and lever? gear puller welded to the drift and oxy the surround? (re drill if it snaps)(porta power good, not good at heat) or are you trying to save the tool? big air tool from the other end if there was a hole all the way through? i do the weld, heat, cool, and rip out, thing or throw in bin method for small stuff. maybe use coke/coal dust or charcoal grind? or any other high tech anti-stickerometer stuff? were you using a non sticker type stuff? biggest ive drifted by hand was four inches...made sure lots of dust(non stick).

fciron Posted October 11, 2010 Share Posted October 11, 2010 Slice off the protruding tool with a cutting torch and then cut or drill out the mass of the drift and then drive out the remnants from the bottom? Most of the other methods seem like more work than making a new drift. Did I miss something obvious? Great project! Quote Link to comment Share on other sites More sharing options...
downsfish Posted March 8, 2011 Author Share Posted March 8, 2011 Update: I ended up with a torch after trying many different ways to remove the drift, it wasn't as bad as i thought it would be and i didn't damage the anvil. I'd rather be lucky than good. So the hole is square about 3" down, then turns back to round. A little bit of clean up to the face and I'll be ready to heat treat, then I'll weld on a couple of feet, which will be two pieces of billet about 12" long welded crossways with a gap between, so that I'll have a place to upset with. It should end up about 300 lbs. and look like Mr. Hofi's. Quote Link to comment Share on other sites More sharing options...

ironstein Posted March 9, 2011 Share Posted March 9, 2011 That is awesome! It looks just like the hofi anvil. I think you are definitely on to something here. Looks great! Quote Link to comment Share on other sites More sharing options...
downsfish Posted May 27, 2011 Author Share Posted May 27, 2011 Update: I finally got around to heat-treating it last night with pretty good results, they're not exactly what I expected though. I soaked it in the furnace for about 2 1/2 hours, then pulled it out and threw it in the water flume (which is flowing substantial water) and viola. Well kinda, actually when I threw it in it got hung up on the chain and just the tip (4 inchs) of the horn went in the water. So I unhooked it and laid it in the water on it's side, about 6" deep, which left the welded on part poking up out of the water. I then turned an 1 1/2" water hose on the top side because it didn't have much water covering it. Looking at the RHC #'s I've put on with soapstone you can see that the softer side and the ends were well under the water and the harder side (except for the step ?) got the hose.

VaughnT Posted May 28, 2011 Share Posted May 28, 2011 That you can make your own anvil is seriously cool. I can't even imagine what an experience that must have been. Looks great, and if you ever want to make another one, just let me know where to sign up! :D Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted May 28, 2011 Share Posted May 28, 2011 You can always re-heat treat it. The numbers don't look to bad for an anvil used in that position -horn to the left. The areas that are low are also areas that probably won't get any heavy pounding either. Quote Link to comment Share on other sites More sharing options...

mcostello Posted May 30, 2011 Share Posted May 30, 2011 Thats gotta be the nicest one off anvil I've ever seen. Do you have a maintenance shop with any hammers?What was the purpose of the vinegar?

nonjic Posted May 30, 2011 Share Posted May 30, 2011 Wow - Cool like,.... very cool if you made that bad boy from scratch theres some serious skill at work My suggestion was going to be flog a drift in from the other side for what its worth !
