Hi Tom. i always like watching your posts as it brings back memories & even though I've been retired for many years when I worked as A Toolmaker at a Government Factory & during The Vietnam War we made heaps of Fuse Timing Components for Both The Australian & American Services we had Vacuum Furnace which was very handy to Harden very small Punches & Dies as we could make them to Size Then harden them without any movement like what happened in The Salt Pots. Also we used The Diamonds on Lapping Plates.. We also Rolled Diamond Dust onto Small Mandrills for Jig Grinding very Small holes.
We live in a sad sad country when materials to build something cost more then buying something already built. That tells us that the material brokers are jacking up the prices, and they want to make all the profit.
Do you think this product can be used to make a telescope secondary plane mirror of 1/10 or 1/20 lambda, or can it be used to make a secondary mirror between these values? Can you explain its sensitivity?
Nice, I like it. I Want to upgrade the 'normal' jackstands for my caravan to a version like you made. Would you be so kind to tell me the type and diameter of the screw you used. I'm planning to use M20x1.5 Thanks very much.
41:01 get yourself an eraser, the ones for pencil on paper, but a big one (usually have a print on it "for big mistakes"). They work like a charm for cleaning sandpaper / (diamond)grindingstones, produce way less smearing compared to those un-vulcanized latex-rubbersticks some woodworkers use for their beltsander and you don't spread so much dust in your workshop. (You still need the brush for the finer eraser crumbs, but they are significantly larger and won't fly a fraction of the distance)
Timeless and valuable post despite its age ;) As instructive as helpful. Thank you Sir. You earn a subscriber. I've been watching your other videos with pleasure and fascination. Really professional.
Thanks Tom. This was a great, succinct video and I even learned a new phrase to throw around and feel smart: Coefficient of friction. Glad you're back!
I was chasing my tail with zeroing a similar a single axis level once. The weight of my allen key set being placed on the table between adjustments was flexing the table and moving the bubble.
Hey Tom, great job but I miss the Monday meatloaf. I hear you are at Area 51 reverse engineering an alien spaceship. Is this why vlogs are so few lately? 😮😂
Thank you so much for this video! I've been trying to figure out how to measure squareness in my home shop without buying a reference square, and this is the answer to my problems!
Hi Tom that was a very touching clip. I know how you feel, only if we had a few more minutes. Your channel has been my #1 go to for more years. Cheers for being your best.
I know of winterisation which is defined as: Winterization is a type of fractionation (also known as fractionate crystallization), the general process of separating the triglycerides found in fats and oils, using the difference in their melting points, solubility, and volatility. Winterization is an oil refinement technique commonly used in biotechnology.
I had considered this threading method (but the opposite way i.e. cutting inch thread on a metric lathe) soon after its launch many years ago, but regarded it too complicated and forgot about it. But recently it started to bother me again. I re-watched the video and understood it better. Oh yes I tried it and what a sweet safe way it is to turn a thread to a shoulder. I am very grateful to you and your source for this excellent method. There are really no more steps than threading normal way. You only re-engage on the reverse instead on the forward. It is just that easy and fearless.Thank you Tom.
Hi Tom, I noticed in the background you made some changes to the flood coolant guards on the Brown and Sharp grinder. I’m about to tackle a guard for mine and I would love to hear your experience on how you problem solved and improved the design. I hate the mess coolant makes so I’ve been avoiding it, but I struggle with heat management on some parts.
Hello Thank you very much because of your helpful videos. Ihave a question? Iwill make one ,do you think if the feet’s on the bottom if be bigger is better or smaller?(diameter) I’m waiting for your response Best regards sina Von Österreich 🇦🇹
I'm late getting to this one but thought I'd add a note. My father was a welder on high pressure gas lines and any time he repaired a leak he would initial the work next to the repair. I would doubt that his weld ever failed so I don't know how any one would ever find his work. It is fun thinking about somebody scratching their head if they found it pulling out the pipe to replace it in the future.
As you demonstrate, on fine threads in relatively soft material, you can advance the tool with the cross slide. But there's zero reason to have the compound set @ ~30* if not using the compound to advance the tool. A coarser thread in some 4140, not so much. As far as the temporarily disengaging the half nut. I've become aware of this. Great tip.
