Thanks! I have been using the grinder for all kinds of metal work. For example, I made a knife out of a worn out file, that was fun and the darn thing is sharp. Sharpening knifes, axes, chisels, grinding welds, shaping metal and wood, just to name a few. It is amazing how useful this grinder is...

From what I learned on the fly the motor drive pulley and the tensioner / idler pulleys do need to be crowned. I did not crown either at first but found that keeping the belt running centered while grinding was impossible without the crowning of the afore mentioned pulleys. Crowning those...

Home made including casting and machining the aluminum pulleys. Made mostly from what I had around my shop. 1-1/2 HP 220 volt air compressor motor scavenged from old compressor. Total cost under $100. Works very well, I use it daily and everything around that needs to be sharpened is now...

The tensioner arm is weighted by three 5 pound workout weights and there is also a light spring. My experience is that finding the correct tension is kind of trial and error but having it correct is important not only for belt life but also for proper tracking. I did learn that the high...

Some additional pictures.

Hi Everyone, I just finished a fun project that all started after I built a small foundry for melting aluminum (thanks YouTube for the ideas). The foundry is another subject but it allowed me to pour the aluminum (melted scrap I had) that I needed to make the pulleys for my 2x72 belt grinder. I...

My VFD installed on my Rockwell Drill Press. It is not completely enclosed but it is protected on top and in front. Works great and I added a Hall Effect Tachometer $15 on Amazon.

Just to update this post, the Delta Grinder (previously mentioned) is done and in service along with the Atlas Drill Press. I love using both machines, what a difference from the newer machines I own. In addition the recently acquired Rockwell / Delta 3 phase drill press has the VFD installed...

Very nice job, and it looks like wall space is no problem in your shop. Thanks for the tip on motor overheating at low speed. I wonder if there is something simple that can be done to help cool the motor?

So, yesterday before moving the drill press to is's spot in my shop and putting it into service, I built a Stainless Steel Shield leaving plenty of space for air flow around the VFD. The shield covers the top and front side (facing the operator). The bottom, face, and back side remain uncovered...

Hi, as an experienced Ebay Seller myself, I agree. I suggest when trying to determine an items value to go to Ebay and type in the description of your item using several key words that describe the item. Once that page loads select "Sold Items" on the left menu bar to see the similar items that...

Thank you, I appreciate your advise and will look into this.

Great thought, Thank The VFD is air cooled and has a fan that runs all the time when it's power is on. I considered an enclosure but overheating is the concern. Suggestions?

A couple of weeks ago I won an auction for a 1976 Delta Rockwell 1/2 HP 3 phase Drill Press on Ebay. The drill press came from a school district in San Jose CA. I could not believe I won the drill press with a $150 bid, I think it was because of the 3 phase power requirement. I did my homework...

Thanks Tom, That idea occurred to me but now after hearing it from you I think I will try it, what is there to lose except some JB Weld? Thanks much, Jim
