Cutting in reverse will tend to lift the carriage so the only thing restraining it is the gibs. Cutting normally, the base of the carriage is on the bed of the lathe, and the gibs only have to hold the alignment.
Wonder why the negatives, this is a great video for budget DIY garage lathers like myself! Cool idea, I like it and it works pretty damn good considering!
Welding is a nice easy quick idea. I don't think people understand how much we have to pay for tooling and machines and how few choices we have in Canada. Good work.
i see you have some runout on your chuck. try rotating the jaws in different combinations until you have the least amout of runout. is it possible when you took out the jaws you didnt put them back in the right spots? just a thought.
+Jamie Buckley Hi thanks I have moved them around but this is actually as good as it gets, this is the 2nd chuck, the 1st one the jaws were ground so bad they only touched at the ends. Unfortunately yesterday the lathe stopped working , waiting to hear back from tech support.
Thank you sir! Now I have found a way to save money on parting tools and not lose an old carbide blade as well. Wonder how many tools you can cut from one blade. Also they should not have to be as long as the one you cut.
Gun Nut thanks for watching :) you are right it doesnt have to be that long especially if you just welding it to the square bar stock. I cut 2 from the blade that long for the previous video ua-cam.com/video/DiQNwZifpj4/v-deo.html where I slid it in the parting blade holder. Now that I think of it I probably could cut all the blade tips off in maybe 1" lengths , cut a bunch of square bar stock and spend 15 min tack welding them together and I have a bunch of parting blades. But when you do it this way you are limited to how deep you can part because the square bar stock, so you can just cut a couple of longer ones for deeper cuts.
Parting tools are so cheap and they last a long time. I guess it would be fun to use saw blades for shits and giggles. I'd be concerned about running a spindle that's way off center, asking for trouble there.
The runout is from the 5" chuck this was chuck number 2, the first chuck wouldn't even hold anything. If I put the small chuck like on yours you won't see any of that. Maybe in the USA a parting blade is cheap but a $7 hss 1/2" parting blade shipped to Canada costs $30. If I bought this lathe in 2016 shipped to Canada is around $1200 with no tooling.
Wow. They don't have tooling in Canada? Maybe you could hook up with someone in the US that could pick them up for you then send them to you. I guess you just gotta do what you gotta do.
people say a lot of stuff on youtube but no one mentions for these lathes the cheap ass control board will burn up way before you get a chance to rip ,break,crack or even lose your fingers
I'm suggesting that the wobbliness isn't conducive to parting. But I guess with an o-ring for a drive belt you'll have a hard time ripping the t slot off the cross slide. Didn't say anything about safety.
try that on 304 ss I use my cutoff to on that normal and I have a 7 x 14 runs great also use cutting oil not wd40 lol on that run out you shure it isn't the spindle ? if 2 chuck does that ?
Parting with blade inverted is often used by those who own mini , micro lathes but often not advertised because it is (or it seems to be) against common practice and somewhat unorthodox, there's a company that is actually making and selling this inverted parting tool : www.eccentricengineering.com.au/index.php?option=com_content&view=article&id=31&Itemid=45 The misunderstanding of this concept is nothing new or unusual.I commend you to be one of the few who thinks out of the box .
Your backing plate would be screwed on, so if you turn it in the reverse direction it can come off; and does. Just weld one correctly. It's a good idea, But ask yourself, "why is it that NOBODY ELSE" turns in reverse. Unless you have modified it with a pin and not advised your viewing public, at which point you should advise the viewing public. Unfortunately ignorance is not an excuse; not in a world where people can be hurt. IMHO
The backing plate is not threaded on it is it bolted on and the spindle is 1 piece so not even sure you know what you are talking about it. Why would anyone thumb you up for that shows how much people know lol.
+Moderatemixed ! why and how would the chuck come off? It is bolted on with 3 screws to a backing plate. WHY would there even be a REVERSE direction for the lathe if the chuck would come off? Please explain to all of us Thank you.
Cool idea. Lot better than waiting a week for parts in mail.

The worst chuck/spindle runout I've seen on UA-cam. I have a runout 3 jaw chuck too but this chuck makes my chuck looks perfect :D
Quicker with a hacksaw.

NotSoDumb Really?
Actualy, parting in the opposite direction can be better. Lots of people prefer it.
with that wobbly shit you're gonna rip the t slot off your cross slide when it snags

It's AL WD40 is fine for that. Tap Magic for AL is really good stuff.
😎👍 nice job
It would be a lot better if the chuck ran true,?.

I'm sorry but this is the worst video I watched, unless you were trying to show what not to do

randomlathe bro 4 years later still has one thumbs up. I’ll tell you who liked it. He himself liked his own comment
When the chuck comes off, you're going to hurt yourself.
