  • I considered making a tapered mandrel, it was only 8 parts (16 ends) and that would have taken longer then simply indicating and twisting them round with the 4 jaw.
    If 800 parts a mandrel would be on the table.

    I began a job this afternoon that is 12 parts, my employers time estimate is 50.4 hours.

    Before starting the 50 hour job he said "throw a quick 3/16" keyway" in this single 2" diameter aluminum timing pulley.
    The customer drawing requires a 3/16" keyway in a 17 MM bore, there is no combination of off the shelf bushings and broaches that will do this. Made a 17 MM broach bushing to fit a 3/16" broach, this went from a 20 minute job to a 3 hour job (-:

        As I consider you quite credible, and as I did have my phone and likewise didn't want to go to a cold outhouse, I made the substitution in kind and utilized it as per your suggestion. Now my phone doesn't work and it smells. Lucky it was only a #1 situation. Do you use an app that I don't have?

        • Sold a mower. Had a 100% honest description, including "POS" in the title. Got mostly lowballs (which is fair and was by design). Had a fella offer to trade and offered 150 led tubes.

          ....alright. Done deal. My shop is about to be so bright I'll be squinting coming inside from noon sun.

          • A couple days ago my friend John found a Stihl 026 chainsaw in its plastic case sitting by the side of the road with some other stuff. There were also four extra chains and a tool kit, but there was a lot of oil in the bottom of the case. He brought it here and took it partially apart. The air cleaner is totally clogged and there is a lot of packed sawdust in the chain drive compartment, but it seems to have good compression and nothing looks to be broken. So we are cleaning it up and hopefully can get it running. It looks like maybe someone was cleaning out some old stuff from a garage or storage shed, and this saw probably had not been used for many years. This model was introduced around 1996 and is now out of production, but many parts are still available. I may finally have a good chainsaw!

              I was wandering where the 150 defective led tubes that were left in the dumpster went. Now I know

                • I did a whole bunch of stuff. All different kinds of stuff at home and in my backyard shop. Stuff that 6weeks ago I wouldn’t have thought I’d be able to do because I was absolutely convinced I would already be dead. I’m just short of 3 years since my quadruple bypass and even though my surgeon told me my heart was in great shape, I had been slowly deteriorating into constant chronic pain and fatigue. I even got lazy enough to set up a mill knee driver for my use with cordless drill. Everything hurt and my shop and motorcycles just weren’t fun anymore.

                  I was on 40mg/day of Crestor and just knew that it was killing me. My Cardiologist ( different from the surgeon) was adamant that I needed that much and was downright belligerent and insulting when I protested. When I’d finally reached a point where I felt I had no choice, I cut my pills in quarters and went to 10mg/day on my own. My nurse wife was flipping out but I just knew I had to do it. I found a new Cardiologist who actually listened to my story and now I’m on 5mg a day along with some super fish oil stuff and 900mg/day of COQ10. 5 weeks later, I have a new lease on life, minimal pain and all kinds of energy. I’ve actually gone through a “detox” period with some major allergic periods while reducing my Crestor intake.
                  I’ve never had allergies previously and fortunately, most of them have now subsided.

                  If any of you feel the way I did…

                  Get a second opinion. I’m glad I found another doctor.

                  • You know when you're trying to look down a long bore, or a tube, etc how your head blocks the light? Today I made a bore light from an old cell phone battery and a LED:

                    The LED is only 1/4" wide, so it'll go down a pretty small bore.

                      I've got a small blue laser coupled to a 1mm fiber for the same purpose. It's amazing how well it lights a bore and you can still get a magnifier over it. Before that it was either the flashlight or the magnifier, but not both.

                      • I use a borescope like this one.

                        I can just watch as it goes down the bore or I can take pictures or videos to watch later. Using a phone or tablet lets me magnify the picture and there is an attachment to look at right angles so if I see a defect, I can go back and examine it in detail.

                        • A while back someone commented that Shoe Goo could be used to splice poly-V belts. Or some other rubber belt. I thought that would be really handy - I could make up belts from the collection of really long ones that I have. So I cut one (5/8" wide), scarfed the ends a bit - 3/8" or so, Goo'ed and clamped it. Today I tested the splice with barbell weights: it held 25lbs & broke at 28-1/2. The weight was only on the splice, not both "sides" of the belt. I was impressed - I very much doubt that I tension a belt anywhere near that much.

                          Yeah, it's kinda' sloppy ... but it was just a test. ​🙂

                          • I swapped out the idler pulley bearings on my Clausing 8520 mill tonight. It went much easier than I expected.
