Thanks to all that replied with your suggestions, I greatly appreciate them. I will definitely take a closer look at the rings and the finish of the cylinder bore and give it another go.

Hi all....I recently finished my Hoglet and after a little fiddling' got it running. But after a few minutes it stopped and I could not get it to start. To make a long story short while taking it apart I noticed that the cylinders pulled off the pistons with very little resistance. I replaced...

After reading "john_reese's" post where he mentioned overfeeding the tailstock, I got to thinking that this is what I may have been doing. I tried again and made sure not overfeed the tailstock an ended up with a nice looking thread. So, thank you "john_reese" for pointing that out....I greatly...

Hi all.... To answer John's question: The workpiece is held in the lathe chuck The die is held in the die holder which is held against the workpiece and guided by the tailstock quill. As far as I can tell the die is going on square to the work. TonyM......how do I go about making sure I'm...

Hi all....I need to cut a 1/8" slot in a piece of stainless steel ( I don't know what type of stainless it is...it came with a PM Research kit). I was going to use a slit saw, but I'm not sure which one to use and at what RPM to run at. One of the slit saws is 3" X 1/8" 30T , the other is 1...

Thank you all for your responses......I made a mistake when I said 9/16-20.....the thread I need is actually 9/16-18. I think I may cut the thread myself after looking at the prices for a tap and die. I will definitely practice on scrap before I try on the workpiece, which is a pm research...

Hi all.... I am pretty new to machining and have a tapping and threading question for you all. I am working on a project that requires a 9/16-20 tap and thread. I have neither the tap or die for that. My question is at what point do you guys cut the thread yourself? I have done some thread...
