I ordered some of Aldo's 1084 a few months ago that was 3/16's so naturally when I put the calipers on it I expected something close to 188 thousandths. I was somewhat surprised to measure 200 to 203 thousandths though. Point is, you may want to call your steel supplier and ask if the 3/16 in...

You can successfully HT 1084 in a coffee can forge with a little practice. Simply heat to non-magnetic, around 1450 degrees F, and quench in canola oil. Tempering 1084 is also easy. 2 cycles of 1 hour each at 400 degrees F. This can be done in a garage sale toaster oven. These are the...

I agree. I can buy a bottle of wine from the grocery store for under $15. (Obviously I don't have an extravagant palate :biggrin:) So why do I go through all the bother of tending a grape vine, purchasing equipment, mashing my own grapes to make my own wine at what is probably 5 times the...

Here's a shot of the grinder tilted horizontally, and also a short one minute video...not a nickel test, but a PENNY test. No vibration to speak of and the penny never gave a hint of movement from 100% down to about 1%!! Horizontal Tilt The balancing act......balancing a penny through...

Took delivery of an Esteem Grinder a couple weeks ago and thought I'd post some pictures of the build. It comes in about 6 boxes in order to save on shipping. The grinder weighs 160 lbs all told, with about another 20 or 25lbs with the horizontal plate and stand. Took about 2 hours to put...

A disc sander, even a cheapo like those available at HF are a good investment for getting flat scales. Try to find one thats a 9" so that you can use regular sized sandpaper and cut your own discs...a lot more variety in your choices of sandpaper that way. Assuming your knife scales are around...

Jax is absolutely correct! It would be extremely rare for anyone in the U.S. to have 3 phase power dropped to their house....none of us have it. The vfd performs that bit of magic for us, converting either 120 or 220 single phase into a 3 phase output which is sent to the 3 phase motor. Speed...

I would also like to point out that the KB Electronics VFD's are highly regarded and have a price to reflect that...around $350 or so. Many guys start out with an offshore VFD widely available on ebay for around $120 if memory serves. I haven't heard any complaints about these vfd's other than...

Just to clarify a little about what Ed just said, those motors would work fine with the KBAC 29D vfd. If as the OP mentioned that he's going to use a belt and pulley system to start things off he won't be able to use these motors as they are 3 phase and require the vfd. Which ever motor you...

The maximum size motor that you can run on a 120V 20A circuit is about 1.5hp. This is what many consider to be the bare minimum when building a grinder. That said, I'm running an Esteem grinder with a 2hp motor and a KB Electronics model KB27d variable frequency drive (vfd). However, I have...

There's nothing "special" about their graphite, I doubt that they're having there graphite specially formulated...it'd cost them a fortune. ANY conductive metal will work. All you're doing is passing the electrical current on to the electrolyte. You could use copper, aluminum, steel, or...

I just recently purchased a grinder after considering 4 brands, Northridge being one. One of my criteria was to be able to flip to horizontal. At the time, and this was just 6 or 8 weeks ago, Northridge had yet to let anyone know what their options pricing was. One of the first to be revealed...
