Review: you will need time and rework to put this together. - I will start by saying that this machine does indeed do what it says it does. HOWEVER - be prepared , the instructions are all but useless for using this machine; the assembly instructions are TOTALLY useless and the parts diagram looks like a preschooler drew it. The machining on the parts that NEED to be precise at least are. Other parts are rough and just finished enough to kinda allow them to function. If you are mechanically inclined and are up for doing a BIT of remachining then for the price this will do the job.
