Re: washer identification

I just made one of those for the muller I'm rebuilding. In this case, it was made of 1/16" thick sheet steel. It's a square washer with a couple tabs on opposite ends that engage a fixed plate that's mounted on the bottom side of the washer. The plate stops the washer from spinning, and one of the c...

Re: Woodinville Shops

For some reason, tiny parts are more intimidating to make than the big stuff. :shock: Small work requires a different mindset, one that is not usually comfortable for many machinists. I specialized in small, and do not do well with large. For what ever reason, I have the patience for that kind of w...

Re: My new mill

Placing a mill in a corner can cost you the ability to work long pieces. It also complicates accessing the turret, should you have need to move the ram. Beyond that, I can't think of a less than acceptable reason for not taking advantage of a corner installation, especially if the work you do is job...

Re: Hand grinding tool bits

Not being a metallurgist, I can't address the idea of letting HSS sit for a couple weeks, but such activity is known to exist. For example, aluminum that is capable of being hardened and that has been solution annealed will harden with time. It's also known that time relaxes internal stresses in mat...

So you've never found those little inspection tags in new clothing. I've found lots of them.
I'm amazed that the tags are still with the clothing when the items get to Goodwill! :P

Re: Chinese Lithium Batteries: Boon or Time Bomb?

I could be wrong (I likely am) but you may discover that Makita is having China make their batteries. If memory serves (don't count on it), China is the source for lithium, anyway, so why not just let them produce the product, too?

I welcome corrections.

Re: Engraving need , laser or rotorary or etc.

I do have two different size sets of stamps . I could stamp one to several digits at a time , but not enough to stamp the entire number at one time ... Steve S If that's the case, using a straightedge to locate the stamps for each series you create, and use an arbor press instead of a hammer. By do...

Re: Brazing Brass

The dump door on the muller I'm working on had broken hinges, both made of a cast copper alloy. In breaking, they were badly distorted (the muller got tipped over), so I made a fixture from asbestos (I have a good quantity of the stuff) to hold the pieces in alignment, then I used TIG to weld them t...

Re: Engraving need , laser or rotorary or etc.

I suspect that the "engraving" is just scratch, not cutting. That's not all that uncommon for trophies. And they may not do anything but trophies, so they, for all practical purposes, don't engrave. A guy might be well served to just buy a small set of stamps, which could then be used for other thin...

Re: Tractor v. Diesel Pickup

Chuckle! Yeah, ok, so I said it kind of stupid-like! :oops: :oops: (No hobbits, as one can clearly see by looking at Fats). Douglas Fir trees don't have a buttress trunk like the Western Red Cedar, which is actually larger (at the base) than the fir. It's not as easy to access, though, although near...

Re: Tractor v. Diesel Pickup

Western Red Cedar stump, which was about 8' in diameter. H That must have been an amazing tree! While not as common as they once were, yeah, it would have been something to behold. I seem to recall that 95% of the old growth timber in our area has been cut now. Such trees don't get cut anymore, as ...

Re: How to drill and ream a large-ish hole with drill press.

I’ve been lead to believe that spot drills are better than center drills given that their angle is slightly than the drill bit angle to guide it to center. That argument simply doesn't hold water. Spotting drills have come of age due to CNC operations (often to eliminate a second operation, the one...
