CheechWizard Posted August 21, 2020 Share Posted August 21, 2020 my very nice neighbor offered me this little band saw he picked up for practically nothing at an auction. of course i obliged. I also hit up the owner of the suspension shop down the way about his scrap pile, told him i could make forge him something neat in exchange for a few pounds, he didnt seem to think twice about letting me have at it, made 3 trips on my skateboard and when i came back the last time he had thrown pair of king pins to my pile. anyone have any experience forging these? the spindle is also a hand down from the neighbor, what a guy.

Frosty Posted August 21, 2020 Share Posted August 21, 2020 Sure, don't forge them over 5,000 RPM. it says so right there. King pins are usually a medium carbon steel for toughness over hardness. No telling what alloy they are anymore, you'll need to do some experimenting to determine specific characteristics. Frosty The Lucky.

Randy Griffin Posted August 22, 2020 Share Posted August 22, 2020 I think that says 15,000 RPM. Forge away. Quote Link to comment Share on other sites More sharing options...
CheechWizard Posted August 22, 2020 Share Posted August 22, 2020 i don think ill be putting my parker majestic spindle assembly any where near the forge, or running it anywhere near 15,000 rpm's for that matter. Quote Link to comment Share on other sites More sharing options...

BIGGUNDOCTOR Posted August 22, 2020 Share Posted August 22, 2020 Looks like possibly a spindle for a tool post grinder. Quote Link to comment Share on other sites More sharing options...
671jungle Posted August 25, 2020 Share Posted August 25, 2020 2lb hammer with what looks like JAPAN and WECL or WECO stamped on the underside and this lil ball peen I found in the dirt at a job. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 25, 2020 Share Posted August 25, 2020 Was the doming on the end from a lot of breaking up concrete or other masonry work? Quote Link to comment Share on other sites More sharing options...
671jungle Posted August 25, 2020 Share Posted August 25, 2020 2 hours ago, ThomasPowers said: concrete or other masonry work? Not sure. It was a $1 recycle center find. It is a nice weight. The 3lb and 2.5lb are what I use most, but that extra 1/2lb off will be nice on the shoulder for the finer blows. Quote Link to comment Share on other sites More sharing options...
Scott NC Posted August 25, 2020 Share Posted August 25, 2020 Have you got a sandblaster, 671Jungle? Quote Link to comment Share on other sites More sharing options...
671jungle Posted August 25, 2020 Share Posted August 25, 2020 I do not. Curious Why? Quote Link to comment Share on other sites More sharing options...
JHCC Posted August 25, 2020 Share Posted August 25, 2020 That will make a nice rounding hammer, once cleaned up. Pre-domed! Quote Link to comment Share on other sites More sharing options...
Scott NC Posted August 25, 2020 Share Posted August 25, 2020 Just wondering. It's that ball peen hammer head you found. It's begging for a deep scouring under the nozzle. There are other ways, but what fun blowing all that crud off there! I like crusty layers of rust more than others, but not on tools. Nice finds, at any rate!

ThomasPowers Posted August 25, 2020 Share Posted August 25, 2020 Wear patterns can often indicate how a sledge was used/abused. Wear can also help with dressing the face to a more usable shape as well as sharp transitions tend to get abraded away leaving a more rocker or domed face. For the ball peen I'd dump it in a container of vinegar, totally immersed, for about a week and then scrub it off at the hose bib. No sandblasting needed; though unless oiled after the wash off it will flash rust a bit. Quote Link to comment Share on other sites More sharing options...

Apologies the ball peen slipped my mind. i was wondering how to get it all off. Maybe tumble it in can with some bearings. Quote Link to comment Share on other sites More sharing options...

Thanks Thomas, great thing to keep in mind. I will take a closer look. I was already going to test the hardness and go from there Quote Link to comment Share on other sites More sharing options...

JHCC Posted August 25, 2020 Share Posted August 25, 2020 I would go with the vinegar soak as well. Quote Link to comment Share on other sites More sharing options...
Scott NC Posted August 25, 2020 Share Posted August 25, 2020 So would I if I had no sandblaster. I guess that is why I asked. Or tumble it in a can, as mentioned. It never occurred to me to mention an alternative. I'm getting daft. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 25, 2020 Share Posted August 25, 2020 Now you didn't suggest putting it in a wooden barrel and adding a couple shovelfuls of sand and having the apprentices roll it around the courtyard for a day of two... Quote Link to comment Share on other sites More sharing options...
Scott NC Posted August 25, 2020 Share Posted August 25, 2020 Place it carefully in a chicken wire lined gunny sack with rocks and toss into the deepest part of the river. Current is best for agitation. Anchor carefully. Check periodically. Quote Link to comment Share on other sites More sharing options...

Frosty Posted August 26, 2020 Share Posted August 26, 2020 Submerged completely in a plastic bucket with dilute Naval Jelly will convert the rust back to steel beautifully. Rinse neutralize with soda, dry and oil. If you let it dry right out of the solution it'll turn iron phosphate black. Frosty The Lucky.

671jungle Posted August 26, 2020 Share Posted August 26, 2020 Thanks for the suggestions y’all! Unfortunately I do not have any apprentices or a nearby river or a laser. 14 hours ago, Frosty said: Naval Jelly will convert the rust back to steel beautifully.

ThomasPowers Posted August 26, 2020 Share Posted August 26, 2020 And of course the electrolytic method of removing rust requiring water, baking soda and a car battery charger---the old cheap type. Lack of Minions, rivers and industrial/military grade lasers shows poor prior planning on your part. You should at least have *friends* with such things if you don't have them yourself!
