BobStrawn Posted September 20, 2009 Share Posted September 20, 2009 So I am innocently minding my business making a jig for the belt grinder out angle iron from an old cheap bed frame. I cut sections, grind the ends to eliminate burs, no problems. Then I chuck in a brand new mid grade drill biit in the drill press, and start to make a hole. I am using water mixed with ballistol for cooling and lubrication. Steam is being produced, but the bit and hole are staying wet. The hole just starts to punch through, coolant is flowing through the hole a bit, still it is all staying wet, when suddenly it is like skating on file steel. check the bit. not dull. I try another bit, skates. I chuck in a serious and sharp carbide bit, and it skates. I have used some nice work hardening steel before, but this is amazing. I am going to have to fire up the forge and punch this stuff. The bed frame is pretty cheap, if the old plastic feet and fittings are any indication. What sort of monster weird steel have I run into, and what should I be using it for? I may try making a rasp out of this stuff. It sparks about like O1 does. Seems a bit high on carbon, for a bed frame Bob Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted September 21, 2009 Share Posted September 21, 2009 Yes, bed rails are high carbon steel. They have to be light and strong. I've known a few small rolling mills that produced bed rails and fence posts. They all started with old RR rail! Usually split into three sections or more, the bulb, the web and the flanges. If you're getting part way through and then having trouble, then your drill is probably going way too fast. Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted September 21, 2009 Share Posted September 21, 2009 I read in one book that some bed rails are Cor-Ten steel. They were making wood chisels out of it. Cor-Ten is also used in manufacturing some of the ocean cargo containers. Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted September 21, 2009 Share Posted September 21, 2009 (edited) You gotta figure that there are some really big people out there and they sometimes engage in some, ah, rather bizarre "athletic" activities. Sometimes even high tensile is not enough. Not that I would know anything about that. So, how did you get those ring bolts in the ceiling, anyway?

forgemaster Posted September 21, 2009 Share Posted September 21, 2009 Sixty Minutes (Aust version) did a feature on the ship graveyards of india I think, where it showed these ships being cut up by oxy, dragged ashore, cut up smaller, then rolled via a rolling mill into bars and section. These bars could be anything from crankshaft to hull to conrod you would not know or as Grant suggested rail. Mild Steel is not always mild steel despite what it gets sold as. I've even seen towbars for pulling horse floats that some nut has made from bed iron. Now that was just like cherynoble powerstation, an accident just waiting to happen.

MattBower Posted September 21, 2009 Share Posted September 21, 2009 A while back I sent off a piece of bed frame angle for analysis, along with some other scrap steels. Glenn saved the results to the junkyard steel blueprint. The bottom line is that it was 1055. Which isn't anything special by tool steel standards, but it should still get you RC 60.

thecelticforge Posted September 21, 2009 Share Posted September 21, 2009 I could be the gremlins. Years ago, I was helping my father cold shoe some horses. About half of one box was akin to beating on a shoe made from coil springs. The rest of the shoes were normal. It's gotta be gremlins.

irnsrgn Posted September 21, 2009 Share Posted September 21, 2009 about 350 rpm and the old black cutting oil and a black cobalt bit. constant steady pressure and never let the bit make even a half revolution with out pressure on it.

BobStrawn Posted September 21, 2009 Author Share Posted September 21, 2009 (edited) Yes, I admit I had the drill press speed to high for tool steel. In my defense, I was drilling through a bloody bed frame. Who knew it was good stuff? Then again, as I dug through my piles of collected steel, I was looking for ridged and solid. I should have figured it was somewhat decent steel. Now I need to see how well it holds an edge and how it holds up to heat and hammering. It would be neat if it were Corten, but I don't think this one is. I keep looking at some of the worse sculpture around town, wondering if the people who own the property are as tired of the sculptures as I am. I am tempted to offer to haul the sculpture off for them. This would be win-win, no more eyesore, lots of scrap corten! I will try working it as if it were 1055. 1055 with an edge temper makes for a seriously tough blade. As I recall, it makes decent throwing knives, since it can take a beating. If it holds and edge at all well, it might make a good chisel. Bob Edited September 21, 2009 by BobStrawn Quote Link to comment Share on other sites More sharing options...
Ten Hammers Posted September 22, 2009 Share Posted September 22, 2009 I have a friend that is due to retire from the FDNY. Over the years we have talked about many things. He once told me of the steel (specific) for bed frame in NYC but I have forgotten what it is. I recall seeing decals on bed frames regarding this specification anf NYC.

CBrann Posted September 22, 2009 Share Posted September 22, 2009 Found out the hard way not to hot bend then quench bed steel. I had a short piece I was using both ends to make a bracket.. .. Quenched both hot ends from bright red and promptly dropped the piece on the concrete floor.... Then I swept up the bits... who knew?? Thats a a hard way to find out about high carbon bed frame. Weygers makes mention of it... but Some of us were not paying attention to where the scraps were from.... Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 23, 2009 Share Posted September 23, 2009 I generally don't quench anything anymore; just toss it into the desert to normalize. Saves a lot of swearing in the long run... Quote Link to comment Share on other sites More sharing options...
Sweany Posted September 23, 2009 Share Posted September 23, 2009 Grant, I had to switch out my bed rails for Railroad Rails, makes dusting bit difficult, but oh well. :) Quote Link to comment Share on other sites More sharing options...
thecelticforge Posted March 6, 2010 Share Posted March 6, 2010 I had fun with a bed frame today also. I planned on cutting some pieces to hold up the floor of a concrete slab I was pouring. I put it in the vise and started cutting with my saws all. I thought that it was going as smooth as butter. However, it wound up removing the teeth on the saw blade. I think I have some great material for a set of wood cutting tools. Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 11, 2010 Share Posted March 11, 2010 Drilling bed frames isn't too hard if you normalize it first. Just chuck up a non-plated 16d nail in your drill press, turn the press on and apply the nail to the spot you want to drill using a firm pressure keep at it till the frame hits black heat and let it cool slowly. A good cobalt bit shouldn't need this treatment to make hole though. Frosty the Lucky. Quote Link to comment Share on other sites More sharing options...
