Thrust bearing and shroud for the Paramo vise

A couple of weeks ago, I overhauled the Paramo vise and ordered a thrust bearing to reduce the tightening torque on the crank handle. That requires a shroud, as the bearing is a 3 part assembly with an open race that would attract grit and filings.

Here's another job for the 3D printer. I've held off making this on one of the CNC lathes, as printing it would be significantly quicker and easier while being perfectly adequate for the application. 

Modelled up the assembly in Fusion and created the shroud. This will fit over the bearing and the big end of the crank screw, being held in place with a large o-ring.

Exported to the Orca slicer and uploaded it to the printer. Print time 5 mins.

Finally, I've lost the large washer that sits between the spring and the split pin. So I can print one of those too. 19.5mm ID, 30mm OD, 6mm thick.

And then, assemble the parts onto the moving jaw, using cable ties to keep the spring compressed. Then cut the cable ties, grease the bearing, screw and ways and finally fit the moving jaw to the main body.

Phew. Finally.

Don't forget the o-ring:

Ooof. That one snapped. Try again:

Job done. I may be required to mount it on one of the benches and put it to use.
