Admanfrd Posted February 3, 2014 Share Posted February 3, 2014 Wouldn't it be cool to forge a hammer and temper it blue? When i make my hammer, i want to do this. How do i temper 1045 steel to blue? thanks! Quote Link to comment Share on other sites More sharing options...
Daniel.85 Posted February 3, 2014 Share Posted February 3, 2014 It wouldn't stay blue if you used it, temper colors can wear off. http://en.wikipedia.org/wiki/File:Tempering_standards_used_in_blacksmithing.JPG Quote Link to comment Share on other sites More sharing options...
Frank Turley Posted February 3, 2014 Share Posted February 3, 2014 I suppose blue would work for a temper. Personally, I temper my hammer faces to a dark straw which is harder than a blue temper. The blue color is superficial. It is a very thin film of oxide that can be rubbed off or worn off without too much trouble. Therefore, you must ask yourself, "Why am I doing this, if it is ephemeral?" If you insist and you have a highly controlled furnace or oven, try holding the scale free hammer head at 563 degrees F. If it's a countertop oven or a kitchen range oven, you may have two problems. The temperature may not go that high; most stop at about 500F. Furthermore, those appliances cycle above the set temperature range. They go above and below repeatedly to shoot for an average. Another route to go...bury it in a steel box of sand and place on the forge. Keep taking a peek until blue shows. Also, a muffle situation may work, if you have a pipe you could heat and place the hammer head inside the pipe, watching for color. I don't harden the eye of the hammer head. Being thin walled, it sometimes cracks. Quote Link to comment Share on other sites More sharing options...
Admanfrd Posted February 3, 2014 Author Share Posted February 3, 2014 ... well, i guess it would be cool for about 5 minutes until it wore off. thanks Quote Link to comment Share on other sites More sharing options...
brian robertson Posted March 2, 2014 Share Posted March 2, 2014 what about just using gun blueing? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 2, 2014 Share Posted March 2, 2014 As mentioned blue is rather soft for a 1045 hammer but might be ok for a higher carbon content hammer. It will wear off on the face rapidly but you may not put much wear on the body of your hammers. Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted March 2, 2014 Share Posted March 2, 2014 what about just using gun blueing? Funny thing about the English Language, verbage. Gun Blueing is actually Browning. Gun Bluing is actually a semi-controlled rust. An Oxide layer that is then controlled with oil to stop/slow down the rusting process, at a particular pigment Quote Link to comment Share on other sites More sharing options...
Admanfrd Posted March 3, 2014 Author Share Posted March 3, 2014 I am going to use 4140. Faces silver, body blue. Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 3, 2014 Share Posted March 3, 2014 This is a fun thought for a new comer to the craft, I did similar meaningless things when I started. Not meaningless to the doer but in the practical aspects of the craft these kinds of things don't make a better project and can actually make for poorer quality. Blue is over drawing the temper, I drew mine to dark straw on the faces and purple around the eye. Of course it drew farther than I thought it would, (part of the learning process, many things don't go as planned) and the face ended up dark straw bordering on purple and it marks too easily. I'm always dressing the face to remove the dings. If you really want a blue hammer gun blue is for exactly that or do like they did traditionally and paint it. Yes it was tradition to paint tools after paint was invented that would actually help preserve the metal and really helped identify a craftsman's personal tools or the business's tools, etc. My shop colors are "Hunter Green and Gold."

Ric Furrer Posted March 4, 2014 Share Posted March 4, 2014 Epoxy paint. I am about to paint my tools bright pink...cuts down on the losses as one can see a bright pink tool walking away. Ric Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 4, 2014 Share Posted March 4, 2014 Patrick also in Wisconson, working for Scot Forge, uses hot pink as his tool colour; says people won't even borrow his tools much less walk off with them... Quote Link to comment Share on other sites More sharing options...
Rashelle Posted March 5, 2014 Share Posted March 5, 2014 I used hot pink. It way reduced the incidence of theft and reduced people borrowing them too. Seems to me it was only the guys that were secure in themselves that would borrow them, and they were the ones that would return them anyways. So it was a good thing to do. A great color to mark ones tools. Quote Link to comment Share on other sites More sharing options...
