Just what I wanted. 1/26/2018

I am a garage/basement hobbyist and I think you are too if you are reading this review. So far, the machine is perfect for my needs. My motivation for buying this was to make some part for a hot rod that I could not otherwise buy. The three jaw chuck spins at .003 right out of the box. I have not tried to fuss with it yet to get it better. I bought a 6" four jaw chuck, the backing plate blank that was included with the lathe made it very simple to mount. Everything works and the machine runs pretty smooth. I have not done much with the mill yet. My only issue with the milll is that the spindle is quite high above the carriage and vice. In order to mill a small part using an end mill in a collet you will need to come up with a solution to raise the work piece. I happen to have some 6" cast iron riser blocks and they work quire well. I was able to mill some straight lines in steel without a problem.

I do recommend following the break in procedure and doing the oil change. As a matter of fact, I will be doing another oil change soon. There was quite a bit of metal in the bottom of the bucket from the first change. The machine takes about a quart of oil.

The shipment was prompt and the lift gate delivery was a lift gate. However, you need a forklift or an engine hoist to move it around once you get it on the garage floor. The lathe comes fully assembled and covered in grease. I took the entire machine apart, mainly to facilitate moving it to the basement, and then cleaned it and reassembled. A few parts needed to be de-burred, but in general I was happy with the design and the construction. As you can see in the photos, I used the HF Yukon cabinet as a base. Works well if you take the wheels off. I tried it with the wheels and it was too tall and scary.

For the price and the size I highly recommend this machine. I really like the lathe distance over the bed, it will allow me to do many things that you could not do on other small machines. Of course, bigger is always better, unless you are the guy hauling it to the basement.

9729 lathe combo 1/2/2018

Good product , need to advise customer that they will need to clean the lathe from when they made it ! Lathe was greased very well when I received it but the metal shavings from when it was made was in the grease ! Still happy ! Had bad delivery service keep putting me off to deliver it from Shreveport Louisiana, so me and my wife drove to Shreveport to pick it up on a Friday at 7:45 pm we live one hour and fifteen minutes from Shreveport and we paid for lift gate service but other than that I’m still happy thank you!
