I don’t recommend using a push style knurling tool on a small lathe. By small, I mean smaller than at least a 14-15” model, but preferably larger. Knurling puts a great deal of pressure on the spindle bearing. If you almost never do knurling, you will get away with it. But if you do it even fairly often, I highly recommend getting a scissors style tool that squeezes the shaft instead. By the way, there’s a very good reason why most chucks have three jaws. It’s like a tripod. Three jaws always contact the work, even if as it comes from the mill, it’s not actually round. More than three jaws, with a scroll chuck, will always have one or more jaws that either don’t touch the work, or are touching with varying force. Either is not good. Only use the four jaw scroll chuck for work that is already machined to an exact square or round. Otherwise use the three jaw scroll or the independent four jaw.
I am looking at this lathe vs Grizzly G4003G. The variable speed on the PM is nice but not sure if the power would be there at low range. Especially for threading. I am a retired machinist, and I ran 144" vertical lathes (yes a 12 ft. chuck all the way down to 12" lathes. All the variable speeds had 3 ranges. Can't wait for the review on this one. I know he is thorough.
Being a DC type servo motor it should have good torque at the lowest ranges. Those motors typically have a curve and produce there best torque at speeds ever so so slightly above the minimum speed. I extend the threads on some 3/8" grade 8 bolts on a regular basis so should be able to put it to the test. On my old machine I didn't even use the compound so tool pressures got extremely high. I will likely do it correctly utilizing the compound on this machine but may try it without setting up the compound as a good torque test. Lots more to come on this machine but I have no clue how long it will take me to get it fully reviewed. At this point it's still sitting on its pallet in my garage as I need to do a little remodeling in the shop to make room for it as it is much bigger than the machine it is replacing.
@@dazecars what I find interesting on these smaller lathes is that they’re using digitally controlled industrial style sewing machine motors. I recently bought a Chinese leather sewing machine and bought a one horse motor of that type which came with the controller. They’re not really intended for running a lathe. They are available up to two horse though. When I decided to upgrade some of my 240 volt machines to variable speeds I bought inverter ready three phase motors for them. They’re much heavier built and designed for heavy load continuous running. I suppose for these lathes these motors work, but they’re pretty small and I wonder if they may overheat.
The motor in this 1228 is a very large servo type motor. I have not seen the specs on the HP or RPM range but was impressed with its size. Its not a hard fast rule but the size of a servo motor typicaly indicates performance the bigger it is the better it works. I have had outstanding success using treadmill motors on my my other machines when converting them to variable speed but there is no argueing that a 3 phase motor with VFD is the absolute best way to go all-be-it WAY more expensive. Thats why I went the treadmill option for my smaller machines it worked extreamly well for a lot less money.
@@dazecars I just thoroughly cleaned it, can't believe the amount of grit they just greased over. I haven't had a chance to use it yet, I need to trim the backing plate tomorrow.
@@dazecars I took it all apart, it had scant grease in it, which was good, because less to clean out. the machining appears to be very good all around. I got the back plate trimmed to the correct size, filed all the sharp edges & loaded with way oil & she's good to go. dang, it's a heavy thing when all put together . : ) I consider it a good value.
So jealous. I managed a 9x32 budget model recently but it's no PM. More or less came new as a project. Works good now though and has a huge spindle bore for it's size and a strong motor. It leaves my motor upgrade project to the band saw! 😁
I find It fun taking a "new" machine and getting it exactly the way you want it. 9X32 sound slike a nice big size. My previous lathe was 16X18 so this new one is a huge upgrade.
the Grizzly sale ends tonight at 11:59. i am still unsettled about a variable speed at low speeds with a larger diameter work piece vs a 12" gear head lathe
Looking forward to your reviews on the PM lathe. The Grizzly sale ended last night, and I didn't purchase. I know the PM lathe will cost at least $1000 more when i finally decide and hope it's worth it. Happy Independence Day. Appreciate your channel. It's been a blessing for me.
No treadmill requirement due to this machine already having variable speed but it may get ELS. Not sure yet. It has a gear box to eliminate most change gear switches so I will likely play with it like this for a while before adding ELS
@@dazecars I loved the lack of gear noise on my Atlas on top of the other benefits. Thanks for talking me into it. Now my wood lathe and drill press have treadmill motors. Just finished them. I also use the rubber track for drawer liners. Helps a lower sliding of tools etc.
not yet, just after getting it and shooting the first video I had some medical issues and have been recovering. In other words no time out in the shop to set it up BUT I hope in the next couple of weeks to get it set up and make some chips
Their machines stare at about $3500 and go up from there depending on what size you want and whether or not you are looking for something more hobby or more professional.
I didn't. My experience with PM on my mill, PM728 was so good that I wanted to stick to the same brand. I was considering both the 1130 and the 1228 and the comment that really resonated for me is the 1130 is the biggest "small machine" and the 1228 is the smallest "big machine" In other words the 1228 is the functionality of a big machine in a smaller package.
I have been chatting with machinists that I worked with for 33 years and they like the variable speed in PM but are leaning towards a 12x36 or 14x36. After adding options the 12x28 is the only one in my budget.

It's so fun to see people put new equipment to use!
its fun to put it into use too 😁
I did buy this self centering 4 jaw chuck based on your recommendation 😊
I hope you like it as much as I like mine
@@dazecars I just thoroughly cleaned it, can't believe the amount of grit they just greased over. I haven't had a chance to use it yet, I need to trim the backing plate tomorrow.
Its really hit and miss with import tooling some comes grit free and others are quite gritty

Thanks, I have thoughts of this Lathe, will be glad to learn all for you. :)
There is more to come. If you have any questions, please don't hesitate to let me know.
the Grizzly sale ends tonight at 11:59. i am still unsettled about a variable speed at low speeds with a larger diameter work piece vs a 12" gear head lathe
Gear head lathe will have more torque but I think the pm torque will still be really good

Glad you like the channel! I will try to get that review done as soon as I can but have had a lot of distractions as of late
Nice. Enjoy!
Thanks, will do!
Learned allot out of this video.
glad to hear it
Great choice, however you have committed sacrilege on your 3 in one crowd. Waiting to see your ELS and treadmill motor mods. LOL.

so many good parts on treadmills!!
Do you have a review of the lathe running and making chips ?
not yet, just after getting it and shooting the first video I had some medical issues and have been recovering. In other words no time out in the shop to set it up BUT I hope in the next couple of weeks to get it set up and make some chips
I want one, how much?

Did you look at the Grizzly 12x36? G4003G.
Since Presicion Matthew's is Also manufactured in China now it's not an attraction as before.

I cant imagine having 36" the lathe I'm replacing is a 16X18 😂 😂
👍👍😎👍👍
Glad you enjoyed it
the axa parting tool holder sucks balls. get a grizzly one.
👍
