More PETG Printer Settings

Something doesn't look right in this photo. I just can't put my finger on it.....

3D Printing With PETG

When I bought my 3D printer I knew I wanted to print with something more durable and heat-resistant than PLA. PETG was the obvious choice, as that was what many folks on the internet said was becoming the new PLA. One very real downside with PETG though was the fact that it was a lot more finicky to print with. The first photo below shows how a skirt came out, not sticking to the bed at all.

The next photo shows the globby infill.

Can You Say, "Layer Shifting"?

Yeah, I'd never heard the term before either. Apparently it's a thing with 3D printers.

My Very Own 3D Printer - WooHoo!

My dear wife got me a 3D printer for Christmas. She let me pick out what I wanted, and I went with a Creality CR-10S Pro. Here's my first try at making something, some soft jaws for my Columbian 603 vise:

1994 E350 Club Van PCU Fix

Our church van's engine recently started missing occasionally, so I delved into the problem to see what I could find out. It's a 1994 van with the 5.8L (351 cu-in) engine, and has only 95,000 miles on it. First thing I noticed was that the Check Engine light wasn't on, which means the van didn't know there was a problem. Hmm. So on to the internet. One thing I noticed when researching was that it was a fairly common problem. People would replace a myriad of parts, only to have the issue persist. Among the parts people would replace would be spark plugs and wires, cap, rotor, coil, distributor, Ignition Control Module, fuel pump, fuel filter, along with vacuum leak checks, fuel injector cleaning, and so on. Wow. I wasn't about to go down all those rabbit holes. Well OK, so I did replace the cap and rotor, but they were well pitted and corroded anyway, so it was a good idea. Anyway, where to start? Not much room under that hood, is there.

Angle Grinder Flap Disc Modification

I've got an old 4-1/2 inch angle grinder from Harbor Freight that just keeps on chugging away. It has a 5/8-inch arbor and most discs these days seem to be made for a 7/8-inch arbor. Fortunately it should be an easy fix to get discs with a larger hole to work with my grinder. I figure I'll just put a 7/8" diameter shoulder on the round nut to hold the larger-holed discs, and just flip the nut over to use smaller-holed discs.

Sheldon 11-Inch Lathe Reversing Tumbler Repair - Again - Arg!

Sigh. Sometimes old machinery is a bit of a bother. Take for instance my Sheldon 11-inch metal lathe from 1941. I got it a year ago and the lead screw reversing tumbler casting was broken. It had been repaired previously any number of times but was broken again by the time I bought it. I fixed it shortly after I got it but noticed when the left quick-change gear selector was in position B, the gearbox would lock up tight. I looked into the issue a few weeks ago and found what the problem was. A pin inside the gearbox was too long, which would contact a gear when the pin came rotating around. I didn't want to pull the gearbox off so I tried to reach in with a cold chisel and knock off the end of the pin. I was somewhat successful, or so I thought. I rotated things by hand and the problem seemed to disappear. I put the lathe in gear, turned it on, and it seemed to run fine too. Shut it off, turn it on, shut it off, turn it on, shut it off. Cool, it's working. Turn it on again and whang! The braze broke. Again. Sigh.
