TouchDRO is maybe the most elegant of the low cost capacitive scale DRO's, so take a look at that first. But for not a lot more, real glass scale or magnetic scale DRO's are quite cheap these days and have better accuracy and usability over these capacitive units. I have a bunch of Mitutoyo...

Kind of concerning that the lack of a thermistor didn't trigger the thermal runaway detection. That's how a lot of fires started before manufacturers started properly monitoring it. Are you using the latest FW for your machine?

What's the plan? Hardwiring those connectors, or 3D printing a compact right angle connector? I've heard that these units are extremely sensitive to EMF when hardwired, so shielding the cables (or making your own out of shielded wire) would also likely save you some heartache down the road.

Quick follow up for anyone who wanted to know if the corroded probe is still usable. I finally did a little more stable setup to compare the two probes at high resolution. I used a small grinding vise to hold the Z stage so it wouldn't wiggle around so much when I adjusted the micrometer...

Well it wasn't much of a repair, more of a mild patch up. If I had a disassembly guide or less common sense I would have taken it completely apart, sanded off the rust, and painted or replated the body, etc... I will try to do more tests this weekend to see if I can actually depend on the thing...

Prior to convincing myself to buy the new (but heavily discounted) Tesa lever probe, I found a very damaged unit at auction very cheap. From the pictures it was clearly a basket case, I honestly thought it was only going to be useful to post an autopsy here about how they actually work. It...

So I finally got one of these little babies... The feel of the sliders and crank surprised me in how mechanically perfect they feel. You really need to hold one of these once if you can. 12 Days of Curtsmas

Yeah, we had some discussion on Discord when this came out. Seems like a legit usage of scraping, and should actually reduce friction without wax. The scraping (quality?) itself wasn't to everyone's liking, but that's mostly an aesthetic call, and everyone has their opinions. As long as it's flat...

**** clamps!

Their website is not regularly updated. Mr. King is semi-retired although he still runs a few teaching sessions per year. The Practical Machinist Machine Reconditioning, Scraping and Inspection forum is where you can find dates and contact information, and many people find the lessons helpful...

A new BL-10 is about $4000 in the US, and about $6000 here in Japan. The new ones use a slightly different motor and hypoid gear and can be identified by using a black body, rather than the dark green Metabo sourced motor used by the units I have. There are some people who prefer the older...

Thank you. I actually don't do a real restoration though, it still looks pretty rough. I could have the aluminum casings bead blasted and sand all the scuffs, stains and scratches out of the plastics, but I like the look and character of a well used tool. As long as it's safe, clean and properly...

I've posted several times about the specialized swiss Biax power scrapers and flakers, and how elusive they are over here. I basically check all my regular auction/used tool sites for them on a daily basis, and have managed to pick up several at pretty discounted prices, although a lot of...

Metrological indicators are typically clockwork devices, using tiny gear trains and preloading hairsprings to magnify the small movements to a dial where the value can be read. I have units that are accurate to ½ a micron of resolution, so they are quite capable. The convenience of digital...

So I measured the scribed lines (showing the two points where the straight edge should be supported for the most accuracy) and it looks like they are very close to the Bessel points, but I think that's misleading and length preservation is obviously not a useful goal for this tool. I believe...

I've shown the incredible TOTO ceramic stuff I picked up before, and the other day I was just scanning through my favorite online market and another master square appeared before my eyes. Incredibly it was being sold for less than $20! It's a slightly different vintage and design, but the...

I think one of these may be a better choice.

Okay, good. I misunderstood and feared you were thinking of removing the passive crossovers (as redundant), if you are following their design and left them in place I agree you are all set. The great thing about vintage gear is that they really haven't improved on it, it is still cutting edge...

Fantastic looking system. Having a lot of painful experience in the land of biamplification, it is critical that you leave at least a capacitor on the tweeters to block any DC from reaching them, otherwise they will die a Vikings death (the DC will heat those little voice coils and burn them...

Yeah, I'm familiar with this solution. There's just no way I would spend that much on such a basic plate, and it duplicating functionality (an offset fence) already in the tool. I've never seen the built in adjustable plate slip, it is rigid and secure when used correctly. And this solution is...
