more casting and machining

[Deleted]

well last night i designed up some custom cupholders for my truck, originally i was going to use some coasters that we cast here with the school logo but now I'm debating if i am going to just make some custom WO coasters instead. i like the idea of both i may make a set of each and just have spares or install a few extra cup holders in my truck, jeep, and keep a few for home who knows when i will start making a man cave.

Heated seat covers in the man cave also? Digital home readout center? Now cast W/O cup holders. Holy Cow! Oil

No, no, noooo! Stopping wasting your time on this little stuff. Lunettes. That's where the action is at. I'm telling...2015 is going to be the year of the lunette!

[jeffwho]

This lunette-ic is really jonesing for one!

how much does one weigh? max ductile iron i can pour is 150lb heat

[Deleted]

Schimmmmmmmmmmms, maybe 25 lbs, I will get a weight and dimensions for you

SCHIMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMS, here ya go, I did not scale it but maybe 10-12 LBS. MOOOOOSEY eat your heart out . Originals were forged.

















Now create

the fact that it was forged is interesting. most likely steel then. even iron will fail at very low temperatures. where steel will last longer. if its forged a casting won't hold up to the load. forgings are made for applications that require extreme strength in one direction castings are in all directions.

next year i may make a few out of ductile iron can't sell them I'm afraid but may make some for my own personal use in the woods with my truck

Heres what we got, a done casting that i sectioned to make sure it had no porosity, another done casting with risers on it, i have that one in my truck but i removed the risers didn't machine it at all though.

After that i have a picture of my pattern and gating, and finally a picture of my magma. Magma is a casting software that does a ton of stuff for prediction of the casting. Enjoy.

Oh and these are made of ductile iron with an ultimate strength of 100 KSI. that is about as strong as as cast ductile iron can be without a heat treatment. In tension it is stronger than the standard grade 30 gray cast iron by over 3x. any questions? i have a video of the pour as well if anyone wants to see it.

just finished drawing the lunette in solid works. its not exactly the same, has a few bigger filliets and some sizes i had to guess at but ill post it up later

[jeffwho]

your project with the WO logo was awesome, and I'd love to see the video of the pouring for this part. Is this part the cupholder you mentioned? I can't quite figure out what it is ("F-scipt" new guy). I also can't wait to see the lunette, too, you do great work. That sure looks like a lot of fun - I've never seen the process of measuring, casting, etc. So how many of the guys with the Willease Disease have asked for something with the WO logo? ha ha

[Deleted]

Putting that on your truck out of cast iron is OK?? Strong enough? Is cast Steel something you can't do without a special foundry? Good to see you are still kicking. Are you wanting to visit us for the BH Run? John

Great stuff there Sir Schimmster. Hope your doing well. Great to hear from you. Can't wait to see the Lunettes.

we do cast steel, its not as common for us but do able that being said the original dual wheel adapters were cast iron however no one will let me spectra theres so i don't know if it was gray iron malleable iron or ductile however gray iron is the best guess. This is ductile iron and way stronger it is as strong as some steels. this iron is almost twice as strong as your normal 1018 steel but doesnt have as much elongation. The cup holders are on stand by as i haven't had time to finish them i did mill a bunch of parts but never got to the welding part yet. maybe next semester.

Howdy! Schimmmmmmster!!


Wow!!!

Good work, Thanks for posting!!!

[Deleted]

i plan on pouring a few more next year and machining them all the way

Metallurgy is amazing stuff and heat, stress, welding, blasting, and even machines that allign the make up of the metal itself makes quite a difference. Try and drill spring steel or high carbon steel sometime! Then there is case hardening to a required surface and strength. Stuff that's been in a fire, might look OK but breaks like glass. How each type will wear in use. If you bend it and try and return it. Grinding it. Frame repair and how to weld it. Lots of knowledge needed to work with metal. Wow. Interesting class you took Mr. Schimmster!

Cup holders are done. I'll throw up photos later. Also made my brass brake nuts a while ago and a tool to adjust branded. Working on the engine lately.

WAIT JUST YOU JUST SAY YOU MADE YOUR OWN BRASS NUTS AND TOOL!!!!
Sir Schimster....I think you are my new hero!

[Deleted]

herees what we got, first the brass nuts and brake eccentrics, then a tensioner i made for my alternator, one is on the engine now just slightly nicer (i made 2 one cleaned up better both are ductile iron) then my custom cup holders, made from a 356 aluminum cast coaster i turned a piece and drilled it, built up weld on the back of the coaster and ground flat then welded the piece on, one got to hot and melted the front of the coaster so i grabbed another and threw it in the lathe to turn it to size then repeat. Brass rod for the pin cnced out the middle piece ( i will put a magnet on it and the coaster to keep the cup holder closed and drill 2 holes to mount the cup holder to my pickups door. Cnced out the arms and drilled them in the mill then mounted it all up and boom theres a cup holder big enough for powered bottles. I think i will make another set with WO milled into the front instead of the platteville logo.

oh and the brake tool on the right in the photo is O1 tool steel milled then heat treated to harden it and make it strong as a production wrench.

Very cool stuff there ole friend. I am impressed. Thanks for sharing it here. I see a great future for you. I am glad you are doing well in school. ::)5x

my buddy is casting the lunettes for his casting 2 project, almost cast to size there 18" long I'm machining the pattern tonight, ill try to throw up some pictures soon
