The bung tip was great mate thanks!!
The right hand sticker is classic!!😂👍
Steve thanks for the safety tips, being an inexperienced new lathe owner really appreciate them.
Like the right hand label Steve!!
Very nice your videos so brilliant I like it
Excellent video Steve, some very helpful advice, thanks for sharing and i'm looking forward to the final video.
Dead right Steve - a close fitting plug is essential. Nice job - until you mentioned it I was wondering how you got the pre-load sorted out. Look fwd to that final video.
Great video Steve. Some useful tips there, and beautiful work.
Cheers Rob
Absolutely fantastic video as with part one I have learned so much from your videos attention to detail is great I like the way you explain everything nothing’s missed and it has helped me out with my lathe work fantastic job god bless 👍🏻
Well thank you for watching and for your encouraging words. It makes it really worthwhile for me thanks... Regards Steve
Very nicely done. High quality Work, am looking forward to the rest of the project.
Fantastic video Steve! Thanks for your time! Cheers, Doug
thanks for teaching me good machining techniques
this fella makes some really neat stuff
good stuff, looking forward to seeing it being used, thanks
Great job China Plate 👍
That press is clever 👍
You definitely need a steady.......easy to make for that lathe.
All good essential information 👏 lovely video.
Nice work. Thank you for sharing

Very rare I even bother with a 3 jaw ...Hard to give up the holding power of the 4 jaw... cheers
AWESOME , ENJOYED !!
Steve I reckon you ought to try one of those Sanou 6 jaw self centring chucks. Very low holding pressures and you can get them with very long jaws as well. Great video as usual.
Well, that's good advice, thanks Ron!!
You should have done a video review titled, 'Run-out and Chuck' and shown it flying over the neighbors fence!
Sanou is actually Fuerda rebranded. Fuerda used to be good but is now junk.
I bought a Fuerda and it was so badly made that it was jumping the pinion gears on the scroll plate LOL Took it back and got a refund.
I review items from Banggood, but have no intention of ever reviewing any Sanou product after the Fuerda experience. It would have to be a hell of an improvement to be even half good.
They all look good on the outside, but it's what's inside that counts.
Cheers Rob
Hi Rob, I reckon Sanou have upgraded their quality control lately. I had a 130mm diameter 3 jaw this year and it was perfect. In fact its the best chuck I have had for sometime, particularly with concentricity. It isn't a one off good one either as I have had two smaller Sanou chucks after that and they were great as well. They didn't even have to be cleaned inside, just lubricated a bit.
I do think the Chinese take note of feedback etc and make changes in their manufacturing processes and standards. In fact I have noticed great improvements in all the lower cost Chinese chucks lately. Well that's my experience.
Regards Steve
Hi Steve,
That's interesting news. Well maybe I should think about having another look at them.
I remember one of your Sanou chuck reviews. The Fuerda experience left a nasty taste in my mouth.
I will give it some thought.
Cheers Rob
.
That was a lot of work to machine out the bar on a small lathe, don’t you have a Steady Rest?? Cheers Peter
hi steve when you put the feed on , say when your boring, and you have the bed stop bolted to control the depth of the bearing, what happens if you don,t knock the feed off in time , cheers john
Why didn't you just turn the jaws in the 4 jaw chuck around?
Hi Steve,
What lube are you going to use for the bearings?
A Molybdenum Disulphide grease.
hi steve cani get the link for the bearings pls tanks

Were you able to check the axial and concentric runout on the ER collet chuck? The imports are often faulty in that regard, and the taper you found on the shaft suggests a high risk of being faulty, where the chuck taper is not precisely concentric with the shaft axis. Import collets are also often faulty in runout, and have two tapers to maintain concentricity and axis. Axial runout is also amplified by the length of the tool stickout.
The gap filling with Locktite 638 will also contribute some runout.
If the final tool runout (sum of runout in shaft, bearings, ER chuck, ER collet, and tool) is an appreciable fraction of the chipload for your milling feeds and speeds (which chipload is typically 0.001 to 0.003 inch per tooth), then milling performance will seriously degrade. I've been frustrated by the Chinese ER parts, which rarely meet the precision runout standards advertised, which spoils the milling function you're trying to establish. It's impossible to solve this non-conforming logic of cheap China tools, because of shipping delays and infeasibility of returns to China. You can't inspect before you buy, and you can't exchange a faulty item hoping for a good one next time. I've resigned to having to pay for expensive Western sources of ER componentry to get the specified runout.
It is all spot on. I have found the ER collet chucks to be very good these days. Quality control had improved greatly on all the Chinese tools now. In fact I don't buy anything but Chinese produced tools and equipment now. Many people become obssesed with things like concentricity as well. I have seen people debating if something is running out by .001" thou when this sort of run-out really doesn't matter in the slightest.
There is also manufacturers that sell really expensive ER tooling that are trying to safegaurd their sales by trying to prove the Chinese made stuff is inferior in some way. I have had 27 years in the aerospace industry and used all the best tooling available, yet I find the Chinese tooling the best option to buy. Plus like I say..I'm totally impressed with their precision and quality of what they make now.
How do you conclude that 0.001 inch runout on a milling tool spindle "doesn't matter in the slightest"? If you speed/feed for a 0.001 inch chipload, then most of the tool is unengaged, and only one tooth is cutting. Any milling process suffers the practical limit that feedrates must be chosen *higher* than some multiple of the sum of runout plus tool/material flex plus tool cutting edge radius. Slower feedrates result in failure to cut, where the tool rubs instead of cuts. Runout also limits you to large diameter cutters, where miniature diameters will flex and break. It's a losing game of interacting factors, and without sub-thou runout you won't have any effective options with the ER11 to ER25 formats. The smaller the format, the smaller the runout must be, to succeed. In my mechanical engineering theory and practical experience, 0.001 inch runout certainly matters, and is about the most you can get away with before everything loses process performance and product quality.
Please dial indicate your milling attachment at the tool tip once you get it completed. I am sincerely interested in your project, as I am designing and building similar things and finding mixed success, with the Chinese componentry being a heartache.
