Nice work on that Oil Pan , FYI i’m a retired Woodworker and i’ve used my TBlade Jig saw for many projects i’ve gotten into. those T Blades are sold everywhere like big box stores ,Hardware , Harbor Freight ,etc and i bring that up because over the last 20 years they have come out with a lot of metal and others specific material cutting blades with many of them and the tool you can cut. around bends , corners and around most obsticals fairly easy that style saw used to be. pretty rare and more expensive but. over the last 10 plus years they have become more reasonably priced and often are featured in multi packages of Cordless Tool sets i do think that tool and blade combo has a lot more flexibility than a Traditional Grinder ? A few years ago i had to do rusty body repairs on a older Conversion Van around the big windows a aftermarket. company did a not so great job on installing. and my 4 “ Grinder was just too bulky to do what i needed. so i did use that Jigsaw and a Dremel i do admit i did do that repair in a outbuilding next to my Shop and i had a large inventory at my disposal of the T Blades to select from and expirimement with i also have a rasp/ file set i’ve owned for many years that i purchased for Woodworking out of a Specialty Catalog more than 25 years ago i can’t seem to find that set any longer available anywhere when i began in the Industry they still mailed Catalogs and that set was a Special they ran one time along time ago. i was close to sacrificing one blade on that Van but that’s when i broke out the Dremel
Sorry I didn’t show that, I’ll need to do a video on that, I heard the old high mark is now the new low mark, add 4.5 qts and then mark the new high mark on the dipstick
