Re: Balancing grinding wheels- my new page

It does almost like something staining the wheel. But of course all the most useful information is obscured by the hub, and searching on what is visible proved unproductive. I guess it's not the end of the world to dismount, but I just dressed it, and I'm prone to making Lincoln squeal, so it offend...

Re: Balancing grinding wheels- my new page

I decided the most useful thing might be a picture. Maybe someone will know more about it, and I can learn something.

Re: Balancing grinding wheels- my new page

The one I was given (brand new) with the machine is a Macklin. He called it "gel cell", so that's what I call it, but it appears that maybe that's actually "seeded gel"? It has fairly large blue dots in the AO wheel, where seeded gel is much finer dots. Oddly, I can't find it with Google, and the bl...

Re: holesaw on a lathe

I just did this last weekend. I'm making ~5/8" spacers to offset brake backing plates so I can utilize pull off drums on a heavy full float rear axle that OEM used hub/drum assembly (drum pinned to back of hub by studs, very heavy, real PIA for any sort of work). Anyway, once rough cut to size from ...

Re: Balancing grinding wheels- my new page

You got my attention. I'm not at all experienced with surface grinding. I have a somewhat larger/heavier 6x12 that takes an 8" wheel with the slightly larger ("industrial" I'm told?) taper that makes finding hubs harder and more expensive. But most of my wheel collection is 7", and I've been using a...

Re: Wood Shaper Cleaning Up Steel Block

You have to be a little careful when buying a product suited for etching concrete, as it is often hydrochloric (or Muriatic) acid. I would never use or recommend HCL for this purpose, but thank you, this is (as it turns out) a very timely wakeup. When I first started using that over a decade ago, b...

Re: VFD question

Hmm, never thought about that. Apparently the dust/dirt here in the desert SW is full of fungus spores just waiting for some dampness. One particularly unpleasant variety is responsible for what is called Valley Fever. I had just assumed it was bacterial, but was not sure why the wash soap didn't de...

Re: VFD question

We have a similar problem with the sour smell in "clean" cloths once you start to sweat, especially in the humid late summer heat. Every few loads my wife adds vinegar to a "wet" wash, and adds an extra spin cycle to get them dry enough for the dryer to work at normal efficiency. Most of the time he...

Re: Wood Shaper Cleaning Up Steel Block

Ospho was my earliest exposure to de-rust (and conversion) with phosphoric acid. My uncle was a boilermaker, but between gigs he worked in a shipyard/drydock on the gulf, and they used it in bulk. But you can't get Ospho easily in many inland areas, Concrete etch is available at the local home store.

Re: Wood Shaper Cleaning Up Steel Block

Better yet, get "concrete etch" (not sure what it's called there). Higher concentration of Phosphoric Acid, and much cheaper by content. The stuff I get in a gallon bottle gets diluted between 1:2 and 1:10 depending on what I'm doing, and I generally keep the solution for future jobs until it's near...

I thought I was the only one forgetful enough to do stuff like that.
