[00:01.490 --> 00:08.210] Getting ready to part off the 27th seal. The rest are just sitting there for
[00:08.210 --> 00:17.410] reference off this bar. Clearance is clearance. Here's a tool I was grinding
[00:17.410 --> 00:23.770] yesterday. This tool comes in underneath, plunge in, do the inner taper, come out,
[00:24.170 --> 00:28.450] out, come up here and do the relief groove here that forms the actual lip.
[00:29.510 --> 00:35.010] I've shown this in a video on YouTube before. These are also the jaws with the
[00:35.010 --> 00:39.890] fine serrations on them for grabbing the plastic, which I've shown in posts before.
[00:41.350 --> 00:45.330] Even though the tool is a little tricky, this is an extremely material and
[00:45.330 --> 00:50.870] process efficient way of making lip seals like this. Be careful with how
[00:50.870 --> 00:55.990] much radial wall you end up with here, this thin. If necessary, pre turn your
[00:55.990 --> 00:59.190] socket to get it closer to your final size so you don't end up in trouble here.
#descriptioninaudio Yesterday's form tool in action making custom PET lip seals. The tool plunges in facially and then is fed out to form the inner 10-degree lip surface. Then retracted and moved out and plunged in facially to form the outer 18 degree lip surface. Groove the OD with The parting tool then pause to manually break all the external chamfers except the seal lip then continue to part off. Shift the global datum of all the tools minus Z the pitch of these parts and lather rinse repeat. I have a plastic ring that I can press the seals into to manually deburr the internal parted edge.
