Hello, my name is Adam. Welcome to my home machine shop. I like to take videos of my work and share them with others here. You may find some clips from some of the work I do at my other job as well mixed in. We are a family owned business that was started in 1972, and today I carry on the tradition as a third generation machinist. I try to be helpful and informative with my jobs, setups and work descriptions in hopes that others my learn the machining trade as well. I use a combination of GoPro cameras and my iPhone camera to make clear, informative, educational and enjoyable videos to watch. Please feel free to post comments and questions about my work. I hope you guys enjoy!
Thank God that this history is being preserved as a historic landmark. As you said, hopefully more of the site will be preserved as a museum for the future to see what once made us the most powerful nation on earth.
I know this is an old app but do you know the tin foil is used also to make spacers or you have to do is take two of your spacers together and tear the tin foil off of it a lot of spacers are also closely pressed stacked you can actually take out a thousands at a time
It looks to me that the belt was already riding in the bottom of the grove so increasing the width of the grove as you did will aggravate the issue. If the drill press will be used that will be a problem, belt slippage. I believe a thumping belt is preferable to a slipping belt. Cosmetically they look great.
Was the groove tested against a belt? With the wear on the pulleys and the extra cuts there could be a danger that the belts bottom out, which should not happen as V belts drive on the sides of the belt and bottoming out reduces the drive friction and accelerates the belt wear.
Hey Adam, very nice mix of content, i like how you get comfortable with cnc and also show things like this repair. What i sometimes miss, is just you sitting in your old shop and talking about stuff, like tools or just what you are up to. Maybe throw that in once in a while if you like, like your Tool Tuesdays or so. I enjoy wathing you for more than 6 years now i think and i like your progress and all, keep it up man 😎👍 greetings from Germany, Chris
I would like to see HEPA filtration been put to use in that facility. There seems to be a mist of cutting oil in the air. Breathing that for years, must take a big toll on you. There’s a lot of fans blowing around the air, I think air conditioning units need to be installed to manage the heat and condescending some of the oil out of the air
To get optimum drive with the V belt the pulleys have to be machined within tolerance. Machinery's Handbook gives all the specs. If you don't get a good enough contact between the belt sides and the pulley there is a tendency to overtighten the belt that could damage belt/pulley/bearings
CNC is cool and all, but I much more enjoy the manual machining content. Love hearing those old girls spool up get it done. Heck, I'm such a nerd that I even watch your shaper vids from end to end! Lol!
Hi Abom79; there has been a lot of talk on you comments about your motive behind all the cnc tools, and what you do. Would you address on air; are you planning a production shop, or are you still looking at being a one off job shop, where cnc becomes a tool for 1-10 or so pieces, and future repeats? Thanks.
What gives, two different angles? Look up the spec and use that angle. The pulley grooves wear differently depending on the diameter so indicating on the faces is a farce.
I believe what he's doing is putting it in crooked, lightly tensioning the lock, and the rocking it out of the hole the opposite direction. With the light tension on the lock, the telescoping gauge with hang up at when it's compressed to it's shortest length which will be when the gauge is perfectly 90° to the bore.
For casting repairs like that where there will inevitably be porosity and undercuts at the weld edges I like to use repair comopunds as filler. For this one I would use Loctite PC 725, since it is aluminium. Get it roughly macined to expose the pores and voids, then fill them with the repair putty. Once it hardens it is machineable. Keeps from having to remove too much material to clean them up, and where they can;t be cleaned up, it works great to mitigate the effects of the voids in contact surfaces like the pully sheaves.
Some of those cast pulleys are really shockingly bad, and the companies do the absolute minimum of machining on them that they can get away with. The Southbend is better than average. I can see balance holes, but I wouldn't be surprised if that was only a rough balancing and it was still out by many grams.
