4 jaws Please look grinder grinding, should be able to solve. But need you to tell vigorously applauded, homemade a reliable precision lathe not easy. Material used homemade lathe, Taiwan buy materials?
, But the unwanted access. Grinding small business I can only self-help all materials, not only in Taiwan, where buy online shopping are not afraid.
Thank you for the detailed graphic explanation, the original four jaw scroll fundamentals of the structure as simple as that.
Yes, this little thing is quite simple structure, mainland goods, very cheap.
Lathes shape seems strange with less traditional, rail is square column? Whether announce shape, very curious.
You check Google 3D Warehouse 3D model of my first put up, and you download to play and play well made.
Your lathe spindle is homemade? Precision 0.01mm quite good.
Spindle is the soul of the machine, so-called 上梁不正下梁歪, the spindle is not correct, all crooked.
Spindle to find someone with CNC turning precision axis G6 (for shaft G6 grade) homemade backward.
Seen g6 marked law, so how much accuracy?
-0.006 ~-0.017mm, you can check the design manual, or
http://www.roymech.co.uk/Useful_Tables/ISO_Tolerances/ISO_LIMITS.htm
Find ISO Tolerance Band T (3-315mm size) with ISO Shaft limit nearest Zero (3-500mm shaft size), more than the fast check the manual.
Chuck eccentricity addition to the jaws, other factors to consider it?
Some, bought on to the spindle go, one by one the various parts of the run with a dial indicator, and then gripping something eccentric large then follow it to find the problem.
Your turning pallet cute, where to buy?
Seig mini lathe, height borrowed just good, so I bought a set of Taobao buy.
I always thought three or four claws linked chuck must be in being the center of a circle, linked not think there is aligning and learn a little, thank you!
I can also tell you the same idea, but to buy this cheap little thing, there should be psychologically prepared.
I checked your 3D lathe model, absolutely excellent! But only one minor suggestion, could you please add in the screws and nuts 3D model too, so that we'll have an idea how to assemble it after building all the parts. I hope this is not asking too much. Again, really appreciate it, thanks!
Thanks for your appreciatios. In return to your suggestion I have added all the screws / nuts into the 3D model in my latest 3D warehouse updates. They are all real size ones, so if u want to know which screw / nut to use, just use SketchUp ruler to check the size or pull down the Layers menu in Sketchup to see its name. Their specs are their Layer name.
Hi Andy,
I want to remind you one thing, the holes in the 3D model are real size holes, meaning if you see a 4.2mm holes, you will need to use a 4.2mm drill. This kind of holes (fraction of a mm) are for tapping a M5 screw. Here is the reference:
Hole 4.2mm -> Tap M5
Hole 5.0mm -> Tap M6
Hole 8.2mm -> Tap M10
Reaseach my lathe model a little bit, you will know what I mean.
Your pictures, it seems only one way to advance and retreat A knife carriage? Coupled with a spin axis is not better?
I lathe is my new design CNC engraving machine axis (spin axis lathe), this lathe can independently remove or replace the CNC, so the height limit (lower than the gantry below). plus biaxial feed carriage there will be likely to affect height, which is one the other is to make the the biaxial extension units, must be re-made a high precision ultra-thin slide table I bought in Taiwan aluminum unlike the United States so convenient size extruded profiles are, so I want to ask to have to sell the line of appropriate size aluminum material, be possible to do which is why I buy directly Seig mini carriage to with.
Hello, I can not find homemade lathe article, I do not know whether to link Thank you!
Not start writing yeah! Xiandiu 3D map to themselves arrested for. The Photo too much of the production process, is still brewing inspiration to write .... write does not stink nor long, simple to understand I need a little time to organize inspiration ...
And I will remain in the collection of homemade lathe, think of wandered this, at least I've seen a decent homemade lathe, these original level. Waiting for your formal writing. Thank you for your to encourage encouragement! articles and works!
Thank you for the encouragement!
If the spindle is low and the maximum car to multi-thick material?
Designed to be car about 10cm thick wood DIY Aluminum mini lathe spindle is too high, I personally think that easy to shake, so a low-spindle purely personal opinion, not say for sure. This is also the benefit of their own design, designed to co-own meaning.
Correction, the lathe used independently, in the the central carriage does not remove the car 6cm diameter wood remove car 15cm wood lathe CNC engraving machine, the design is carved wood stick 9.5cm in diameter. Why 9.5cm? heavy stick as Home Depot, BNQ or Homebox seems the most commonly sold, the thickest only to 9cm rough again, people buy less, less than function.
The original spindle Pillow Blocks, I thought for a long time, I did not expect such a simple method, but why two?
In addition Thank you for your selfless sharing, I also have a strong interest in home-made lathe, see your 3D map really learn a lot. Wish you posted some homemade stuff articles!
Pillow Block bearings are self-aligning, the original purpose as the spin axis of the left and right bearing with, it must be adjustable heart, and must be used in pairs. Single will Luanhuang, you try to know the.
Calibration to buy senior Pillow Blocks, center, just two fixed spindle the general lathe spindle design is the degree of vertebral Spindle Ordinary people can not DIY, so I changed this way, as long as the spindle core designed shape of the flange on the Pillow Blocks seems to have a K series is the the vertebral degree-temporarily not used.
To remind you that the humpback the tailstock Pillow Blocks buy the same shaft seat size (Housing), front and rear axis will be the same height. How do I know whether the same shaft seat? Check Asahi, Japan, pillow block bearing Pillow Blocks Specifications know my imitation Asahi inch shaft UCP201-8 UCP201-10 by the look-up table of the same height.
Big Brother If I were you, I would drop sinking rotten chuck for a real.
I would also like you but first the good stuff, in order to replace the current ebay, taobao pay close attention to .....

Spindle hole diameter: 18MM.
Spindle axis: 1 "* 8 teeth <br /> Tao Bao seller can hold the same?
First: Dage have stated axis 1 "x8 teeth. Taobao to choose 1" 8 teeth. You to Taobao Address 1 "8 teeth, but in front of him to write a M33x3.5, I do not know which things to take my word, I would use Ali Want to ask him directly that I 1 8 threaded spindle, buy him which. Available By the way, why M33x3.5 with 8 teeth, the two specifications Metric Inch write is why.
Right right right! Wooden teacher really professional, to see that this small sticking point where I'll go Ali hopes to unlock doubts Thank you patiently doubts wish extra cash
Ask the seller to answer [M33 * 3.5 and 1'' -8] adapter disk the spindle M33 * 3.5 then insert can be installed on 1'' -8 fixtures and store existing ' '-8 chuck Call ~ full circle back to square one these days trouble wood teacher
Seller mean [M33 * 3.5 and 1 "-8] adapter, if your spindle Metric 1" -8 teeth, put the product attached to the adapter, became M33 * 3.5 teeth, just set into the The chuck is m33 * 3.5 teeth.
On the network map (lower left corner of the picture is):

Seems adapter is a small the teeth turn Daya, so I think Taobao buyers should buy: M33 * 3.5 and 1 "-8] or [1" -8 3/4 "-16] folder head no adapter is the best, so this should be [1 "-8 3/4" -16]. confirm with the boss, the Fengyun 1 "-8 spindle, directly available, do not install the adapter head [1 "-8 3/4" -16].
