there is also a low carbon steel 1117 :confused:

High-Strength Easy-to-Machine 1144 Carbon Steel Also known as stressproof. This medium-carbon steel offers good strength, while added sulfur gives it good machinability. mcmaster.com or much more at http://www.niagaralasalle.com/products/stressproof.html

depends if there is enough carbon in the steel. first heat a piece in a torch until red/orange and quench in water or oil see if it hardened.........if yes try it with two links and go from there.

sounds like a nice anvil....... with pics you can get a fair value estimate here. nice anvils are always in demand :)
-
i thought it was to allow the blade to be removed after stabbing .... it allowed air to enter the wound as the blade is withdrawn so a vacuum wont form.....or so i heard :confused:

a smaller set works great for dragging pallets in a truck to the tailend :) -
they look like the same machine ????
-
you can also install a CO monitor to make sure all is well. not expensive :)
-
will your torch melt the sheet metal.......... if so you could probably weld with it rather than braze. nothing wrong with brazing......the metal needs to be red hot to melt the brazing rod.
-
what type of metal ??? how thick ?? generally a small torch tig or mig will all work. for aluminum special flux is required for torch welding.

without the math bend the first piece a little long and measure the results and you are good to go. note the length of the bar and the start point of the bend. when you have bent it you will know the gain/loss for the next pieces. i have bent a lot of tubing and always found a single test piece more accurate the the math. ime

ok 4 inch lead very fast........... i have an experienced machinist i will ask .........
-
ok i get it now let me think about it now i understand the problem these guys http://www.roton.com/Mating_Components.aspx?family=7060295 make a 2 inch od 4 start threaded rod. 2"x1 which gives 4tpi taken together if you went to 2.25 od i think you could cut the threads deeper until the lands just disappear.
-
in that case cant you choose the number ?? as long as the two parts fit together ???
-
does it depend on the nut ??? or on its application ??

ITC 213 Ceramic Coating for metal
johnptc replied to ironantlerforge's topic in Insulation and Refractories

see http://www.baldor.com/products/product.asp?1=1&product=AC+Motors&family=All+Families|vw_ACMotors baldor only makes 220 or 230 no 240 !!!
-
really like the third one
-
fairly thick before quench. .030 to .100 inch helps reduce warping and cracking and burning everyone has different thoughts on how thick........
-
most shape the blade and grind it to about 220 grit prior to heat treat...the final grind, polish sharpen is done after heat treat. care must be taken not to heat the blade and ruin the heat treat.
