The relief angle may help a little. Most shears I've used have a slight relief on the bottom blade, whether it's from an angled grind or that the blade...

[eKretz]

My idea is to grind the top blade the rest of the way to clean-up. Shim it out afterwards if necessary. The item being cut will fold over every time if...

[eKretz]

You can measure a bore in a pinch with an adjustable parallel and NO spheres. Just have to apply flat-to-round correction based on the width of the parallel...

[eKretz]

Looked like more than half a division to me, but the camera was pretty far away. Generally, a ½ micron or .000020" resolution indicator is used...

[eKretz]

Indicator or DRO are both better than dials for me because they're easier to read quickly. I tend to focus on efficiency and getting things done quickly...

[eKretz]

This works especially well if you have a DRO. I wouldn't suggest trying to do this with dials. If you don't have a DRO, set up dial indicators, one registering...

[eKretz]

All of your questions are dependent on the size of your machine. A big monkeywrench in the works from the start in terms of plunge cutting the radius...

[eKretz]

The heat transfer issue is the reason for the sort of out-of-place-looking t- handles on the Rahn version of this tool. With those, the only connection...

[eKretz]

Garolite (G-10) should be excellent. The last shop I worked in did a lot of work for one of the major Garolite suppliers, it is very commonly used for...

[eKretz]

You can call it whatever you want, it acts as a drive key if the holder tries to move. And if that happens, you can kiss it goodbye as well as usually...

[eKretz]

I hate R-8. I have run so many machines in shops that either have a mangled drive key or none at all. I have a QC30 on my machine but mine can use either...

[eKretz]

All of the guys telling you that HSS can't be annealed with the easy tricks listed in this thread are dead on correct. HSS needs to be cooled slowly (VERY...

[eKretz]

Yeah older machines really get the tapers banged up. Especially when the tools you're putting in and out might weigh 20 pounds. We used to regrind the...

[eKretz]

Again, it's not all about the hardening or not, though that certainly can and does play a role. The thermal expansion and contraction can cause cracks...

[eKretz]

Yes, right on. This is exactly what I was talking about earlier....

Hi, my email is [email protected].
Thanks for any help!

PM for contact info if you want it, I'm not going to put it out there on an open web page...

[eKretz]

The "glass bead" from Harbor Freight is pretty good for removing rust and paint, and doesn't leave any residue. It is not like the glass bead...

[eKretz]

On a small part maybe not much difference, the whole part heats up either way. On a large one the entire part must be brought up to preheat temp for welding....

[eKretz]

Bull. Brazing does not require near the preheat that proper welding does, nor a slow post-cool if the workpiece is not irregularly shaped or of very thick...
