A Better Parting Tool Holder. Part 2

G'day...
This is the final part to my new parting blade tool holder.
Turns out it works a treat.
Cheers

Parting off is difficult at the best of times, especially on a small lathes which lacks rigidity. What makes parting off difficult is the accumulated flexing that occurs on the lathe. I.e. There is movement between the saddle, the cross slide, the compound, the tool post, combine this with the over hang from the center of the tool post out to the parting blade. It all adds up. Remove this accumulated flexing and parting off success greatly improves. Bringing the parting blade as close to the center of the tool post as you have done should vastly improve parting off. Also look at some other videos on turning your parting blade upside down. In essence by doing this the parting blade moves out or ways from the work piece instead of into it, thereby reducing the possibility of crashing the parting tool. I have found power feeding works best, set the feed rate to the lowest rate and work up until you find the sweet spot.

Thanks for the info mate 👍 I think I’ve finally nailed it now. I just finished this on the weekend… Works magic 👌 The SAW blade / PARTING blade experiment. kzbin.info/www/bejne/gaXRi6VnqpV7g5I

Unless you have a heavy rigid machine, carbide inserts are almost always a waste of time and money. That parting holder you showed around 16 minutes is faulty manufacture or has been damaged and returned to seller then off loaded onto you. The vast majority of people using carbide inserts are just too lazy or too dumb to learn what even improperly ground HSS tools can do. (Stefan Gotteswinter about the only You Tuber using inserts 'properly' on some 'exotic' materials) Personally, I have two 'throwaway' insert tools, a small boring bar bought by accident and a small triangle insert one I was given probably 45 years ago. I made a holder for the diamond shaped inserts for one specific job, haven't used it since as HSS is way more convenient

Hey mate, thanks for the input. Yeh at the time I didn’t know any different with the parting tool. I’d never seen one before I’d bought that. I know now that it was faulty, but didn’t at the time. Anyway… this seems to do the job, so I’m pleased with it. I’m going to make a few of my own blades… I have an abundance of panel saws blades from work… so I’m going to try make a few tools with the tungsten tipped edge. Might hold up alright. No harm in trying… Good quality blades… and free 😊
