Lathe rebuild Pt.3 - Final episode

Welcome to the last episode of my HBM lathe rebuild series.

Today we're going to replace the 3-jaw chuck with a 6-jaw, rebuild the tailstock and have a look into a problem I run into in the early stages of the rebuild.

After that we'll go through the necessary adjustments to align the lathe so that a straight part can be cut. This includes the tailstock alignment.

The video ends with a quick word about the rebuild and the future of the channel.

I love your scale model! I knew lathes where shimmed to make them level, but never realised that was why.

[JB-ypbd]

awesome videos, the voiceover is great, much better than being blasted with music and i love having everything explained what and why your doing. awesome videos mate, keep them coming!!!

[artisanmakes]

Blimey, that issue with the threading dial could have really caused a bit of damage if you didn't pick up on it. Great video, looking forward to any future projects

[tinayoga]

Absolutely no problem with your voiceover. You speak very well. I'm surprised that you went though so much effort without making anything during that time. To me it is like a kid being able to open a present and then not being able to play with the toy.

I have thoroughly enjoyed this series and the one you did with the SU carbs which took me back to some of my early cars in the sixties, in fact my second car was an 848 cc Mini and my first of many an experience with SU's, by the way your voice over is perfect, in fact as an englishman I 'd say you speak better english than most of the americans on you tube.

[impuls]

I bought a used lathe similar to yours and your vids helped me with getting started! Thanks!

[anandarochisha]

You are a natural learner on the lathe. Good job.

[paulypaulypauly]

Good work. You are a very methodical dude, which results in your machines being clean and functional. I’ve enjoyed the couple of videos I’ve seen so have subscribed. Looking forward to you adding a bigger motor with VFD, and electronic Lead screw! 😀

[RyanAUS]

Great little series. Thank you for sharing

[simonpaterson]

another great video, some motivation for me to finally set my lathe up properly.. ive just lived with the taper it turns and sand it out when it matters 😆

[seansysig]

For never using a lathe your first part and previous tedious endeavors to improve the lashes accuracy are well thought out.

[michaellee]

Right on man good for you. I'm liking what I'm seeing . Keep it up.

[goboyz]

Great Video. Well done. Looking forward to seeing more.

[TnCh]

Looking forward to more videos, they are pretty good and entertaining.

[sto]

10:33 - Excellent explanation on that You've done a lot of work on this. I don't think I'll be able to fix mine, might as well buy a lathe that is completely well engineered and buy a used quality branded lathe.

[LordNPS]

@5:52 surely you mean "this was my very first time using this lathe", and not "a lathe" right? Else there are a lot of questions to be asked. Only a manual lathe operator would know the value of power compound feeding with a power drill :) You clearly have a professional background in machining though, that is obvious. Looking forward to seeing your channel grow.

[craigtreleaven]

That 3-D printed part to drive the compound screw looks awesome. Is it available on one of the model sharing sites?

[mike]

on the wobbly runout, try taking some 1000 grit emery paper, wrap it around the checking tool, and spray with wd40, then turn lathe on and slowly insert it, use the tool to help sand the channel angle. i suspect you have some burs and such stick in it.

0:46 the bearing error is not repeatable

I want to thank you for all of your videos. I am looking into either buying a Lathe or a Milling machine. This is a big investment for me, so I am doing months of research.

In the USA there are 3 Commonly resold Chinese lathes. The Sieg, which I think is the garbage lathe you had before, Grizzly, which I think is just a variation of the Sieg, and the Weiss, which is a more expensive brand, that is also known to be resold by a premium brand here Precision Matthews.

I believe your model is the same as the Weiss WBL250F. Current prices from Weiss are 2300 USD. They boast a lot, but have very little specifications listed, and there are very few people who have teardowns and videos of this lathe.
This is also the same model that BlondiHacks uses (the PM1022V which is built by Weiss as a customized version of the WBL250F).

While it's disappointing that a lathe that costs so much would need so much work right out of the box, it's also the best looking mini lathe of it's price range.

I look forward to seeing future modifications and enhancements (make a stand!). And while some others have covered topics like levelling, I hope that you can cover those basics for this particular model and setup.

Personally since I'm looking at getting a mill or a lathe, I'm wondering how much I can get by with adding a milling attachment to this particular lathe. Being able to mill up the the travel of the cross slide would manage 70% of my projects, but having a lathe would manage 80% of my projects, so at minimum with a milling attachment, I could complete 56% of my projects on the lathe.
