1918 TUEC 260

Old meets new? Fit is pretty good, but could obviously use a rubber gasket of some sort. Will still have to figure out how to do a brass front plate and make a key. Thanks again Owen!

Key turned out OK, got some issues to work out with the printer I think. Works great though!

That's awesome!!

Have never gotten into 3D printing, and I am very impressed. How hard is it to set up a print job like this?

Thanks! 3D printing is finicky for sure, but there are lots of good support groups out there and tons of content on YouTube to learn from. I've just started teaching myself 3D modeling so these are only the 2nd and 3rd of my own designs I've printed.

Couple things you might notice in the model... The top of the key cavity is a 45 degree point, this is to get a nicer surface on that part. You could go straight across, called bridging, but the surface is generally poor when you do it that way. The key is tricky for the same reason, the shaft sits on the print bed tangentially, and the blade and handle are suspended, requiring supports to be printed to print those suspended parts on. Similar to the bridging, the surface on the underside is not great.

WOW - great job on the 3D printing. LOL don't suppose I could talk you into sending me the file so I could get someone here to print one for mine?

 

[jrunsvold]

Thanks Collector2!

I've just put them up on Thingiverse. I've also added a version that uses the rubber part from a plumbing test plug for a good seal. Details in the description.

Thank you

Realized I never posted a finished pic. Thanks for all your help everyone.

Very nice! How'd you do the brass? Cover it with a thin sheet, or what?

 

[jrunsvold]

I had a machinist buddy make the face plate out of round stock. It wound up pretty thick at around 3/8, so I split it with a hack saw and cleaned it up on the sander. I still have the other half if someone could use it!

Beautiful!! I need a machinist friend, lol. Don't get rid of that other half...somewhere out there is another plate-less TUEC
