Use these for Harbor Freight Mini-Mill

I've been wanting a set of these for my Harbor Freight Mini-mill and have been watching these sets for well over a year before buying. I saw them on eBay, Amazon and at Little Machine Shop. I settled on Amazon because of the low price and the ease of returning if I was dissatisfied. They all appeared to be the same thing made by the same Chinese supplier. There is a difference in size though - the 1/2" will not fit the Mini Mill table slots, you must buy 7/16". You will see them listed as both 52 piece sets and 58 piece sets. They are both the same. The 52 piece set counts the 12 step blocks as 6 pairs, so if you count actual pieces, there are 58. Both sets include a rack to hold all the pieces. I've seen many complaints abut the rack being plastic, not metal. Mine is actually both - the back wall is metal, and the front rack is plastic. It seems very sturdy considering the weight and heft of all the pieces fully loaded. Another complaint I've seen is about the metal being painted. I'm not sure why that matters, but the "paint" on mine seems durable enough as I tried to scrape it off and it did not come off easily. These are meant to be kept lightly oiled anyway, so I imagine if that if the paint does wear off it won't make a bit of difference. Lastly, these sets are full size, meaning they will work with full-size milling machines. Not sure why I expected them to be smaller (perhaps because I was ordering them for my "mini mill"), so I was pleasantly surprised that they were so large and heavy. I'm very happy with my purchase. It was delivered 3 days before the first date in the date range they estimated. The quality, although obviously cheaply made, is above average and honestly better than I expected based on other reviews. Maybe I had my expectations set low enough? For what you get for the price, it is a real bargain. Other places are selling this exact set for much more money.
