POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[dkemppai]

You can't really print in metal with a home machine.

It is also advisable to have a direct extruder and upgrade the hot end.

Yes, I know. I was going to print plastic gears to replace the old worn out brass ones...
This printer runs a Micro swiss direct drive and hot end. That was a big improvement. Also a tool steel nozzle.

Mostly, I think of the 3D printer as a toy. I keep trying to shoehorn projects onto it, but it never seems to happen. Sometimes a vacuum cleaner nozzle or stuff like that, but no 'real' parts, yet. The gear would be a good excuse to try...

The other thought would be to see if they could be CNC milled. Small endmill in the 24K RPM spindle could possibly mill out the tooth profile. Just haven't looked close enough to see what that would take.

In any case, with an ELS it may not matter. Might not even use the gears again.

You might be able to do a myfordboy trick and print a PLA gear, and then use the lost-PLA method to cast it in aluminum, but that would then mean you'd need more tools.... like a foundry and a crucible. I think the king of random on youtube did a flower pot foundry.

Made a small machinists jack out of a damaged keyless chuck

And used my new 6 jaw (not because I needed to but because I wanted to ) to make a gear shift adapter/ extender for my friend's Fairlane

IMHO ruby nozzles are the right choice for abrasive filament... I've put 10 pounds or so of glass filled nylon through one ruby nozzle!

I succeeded in going from CREO assembly to dxf, cambam, and to good cnc router parts!!

Getting close!

Would you mind translating that statement to English?

Finally succeeded in silver brazing a steel boring bar end onto a carbide rod. Only took five or six attempts

Just finished turning a camera filter adapter that slips into the back of a Canon FD lens to Canon RF body adapter.
I currently sell some 3D printed filter holders that fit into the Canon Drop-in Filter Adapter and would like to do the same for the older lenses.
Simple sleeve with a step that holds the glass filter in place with a friction fit plastic ring. Started with a lump of Al over 2” in diameter. I had earlier tried to make it with threads inside and out to use a different retaining ring but there is really no metal left when done and it split on the first fitting!
Still have to blacken and soften any sharp edges.

He draw some parts in CAD software (specifically PTC Creo), exported them to dxf (a common CAD file format), used a CAM program (CamBam, a common CAM program for hobbyists) to generate toolpaths/gcode, then cut the parts on his computer-controlled router.

Finished some steel riser plates for my lathe yesterday. Today I installed them. A bit of a chore for me, as I had to take apart my engine hoist and carry it down the basement stairs and re-assemble the hoist in the basement. Eventually got everything to line up and lowered the lathe onto the risers. The risers will allow me better access under the lathe and make it easier for me to install my stepper motor for my ELS. Kind of a twofer. The big square looking hole is where the stepper goes.

Afterwards, I broke down the engine hoist, brought the pieces outside and reassembled it. The hoist is back in the garage now. Spent all day doing this - 9am-6pm, my sore muscles are complaining right now.
