@@Anderson-HandForged Thanks! Power hammer is 5 year old now and only thing which get worse is spring. I have to replace it. With time IT het softer and now I have collision in links because of too soft spring.

Those chinese pulleys are machined very precisely so when they are clean you can't even see them rotating.

Flycutters are awesome, I want to build one in near future but they are very sensitive for head tramming. No one want mill huge concave surfaces. And then head wasn't trammed perfectly.

@@mdgchanel4548 what is a point of buying cutting torch when you make big hole once per 4 years in thin steel plate

Spring tensioning of bearings wasn't good idea. I changed that to thread and nuts in episode 16 of this series.

Probably not, it would be very complex and time consuming task to prepare real plans of whole machine

Thank you!

@@Marek_Dobro tak, tylko przy zakupie trzeba zwrócić uwagę żeby był otwór przez wrzeciono, bo są też w wersji do wiertarek bez niego. Tuleja wielowypustowa pasująca do tego wrzeciona ma oznaczenie z532

Changing to taper roller bearing demands changes in quill. Lathe needed.

@@SteelCraft99 OK, understand. Do you make video with accuracy measure of XYZ axis travel? Next project is a big diy lathe?

DIY lathe would be nice and fun project, but not big, max 500 mm between centers.

@@SteelCraft99 You need 38mm or more spindle bore for comfort work with short distance between centers. I have small lathe 350mm from chuck to live center, about 420 between dead centers and bore of spindle 16mm, and this makes trouble when you need cut off or turning sizes, bigger than 16mm. I am sure that your next project, thanks to the experience and knowledge gained in the manufacture of a milling machine, will be just as interesting and educational. We are looking forward to it!

​@@ZVO1996would you go with 125mm or 160mm chuck?

@@mr.ranyhomemade2466 my friend it's not CNC machine. It just electric power feed from PWM controller. Movement can't be set to exact dimensions of workpiece.

Initial idea was to keep cost as low as possible. Linear guide rails bigger than hgr20 gets very expensive. I wouldn't even consider to convert this machine to CNC, I like conventional machines. For CNC I would go with totally different design.

Thanks! Probably it was last one of "crazy setups" in this build.

the setup in the vise would have needed to be tramed extremely well otherwise it would have machined a concave surface, the same effect scaled down to the diameter of an end mill given the relative precision on the rest of the machine is negligible

​@@josephwaldner7752Exactly! with using small diameter tool with small steps (the smaller the better) you can achieve quite good and flat surface without tramming head with very high precision. Also setup of whole turret in vise jaw wasn't very rigid so it was better to keep cutting forces low as possible.

@@josephwaldner7752 interesting, i hadn't considered that...thanks!

@@andrewschroeder9502 Can't be 😂 I will go back to only proper way next time

There are still some improvements on the way 😅

@@Lyhnteld nah, it do the job but isn't what I want :p

Thanks for comment. I will play with carrier frequency in vfd if nothing helps then I will filter it in video postproduction as you said. This sound isn't that bad in real life, microphone makes it worse.

Hi, It wasn't cheap :P I've never calculate exact cost but whole project including buying needed tools etc could reach easilly 1200$

@@hectorrsilvestre9065 Yeah , in next episodes I improved lighting in workshop.

@@MarioEstebanChavezMoo Gracias! es una fresadora ;)

@@georgeukrainsky9352 I wanted to build one. I learnt a lot thru this project.

@doncampbell9991 If the thread you want to cut isn't long I think I would go with solution similar to those die holders for lathe tailstock but with end matching with your Butterfield 2 3/4 handle instead of morse taper.

Buzzing sound is from electric motor. It starts when I put lower frequency than 50hz on vfd.

@@douglasharley2440 Very very satisfying ;) Thanks!

There are three areas where I loose some ridigity. 1. Spindle bearing preloading system. In this video you can see that I'm cutting thread on spindle shaft. Now bearings are preloaded with nuts. 2. Surface between column and turret - I have no idea why it's that bad, when I made it both surfaces were nice and flat. When I was assembling machine I realised that one of them is warped - this will be also improved in next video. 3. Z Axis guide surface on knee. You can live with that by locking Axis , it will be improved later by extra scraping. Thanks!

@@SteelCraft99 thanks for you taking your time to reply! Yeah, i realize you was working on the spindle shaft. Maybe double axial preloaded bearing (good ones) on nose would help, dont remember how you built it. Talking about warpage... Maybe you cut somewhere and had some tension relief, or made it welding on a relatively far place.( Reinforcements?) Gloves also fool us thinking all apear to fix well when cool but pieces are still at 60°c and when final refit comes... Surprise!!!! And yeah, scraping all those ways is the thing. On construction hardware stores you can find carbide scrapers to apparently clean concrete from tiles. Its a cheap source if you cant get the specific ones ( experience talking).

New bearings are still angular contact ball bearings but this time I used different configuration. Previously first bearing was deep groove ball bearing, then angular contact bearing 7206 in the front of spindle and 7205 on the back. Now its two 7206 in tandem on front and 7205 on back - they create "O" configuration: << >. P5 grade.

That sounded good. (now thinking out loud, tell me if our logic is the same) First configuration was logical, you tried to fight radial forces first, but deep groove geometry probably is not working well under preload, you are pulling balls against a wall on an angle wich is kinda paralell to radial forces so youre having wobble on the spindle until balls are pressed into the depth of the groove, angular contact or conical dont allow the pressure angle to change so you kill the woble from start point. Am i right?

Yeah, our logic is the same :)

@@user-cg3em4cw4f I'm trying my best

@@mr.ranyhomemade2466 Hi, spindle is z4132 from aliexpress. There are two types of this spindle. One with hole thru and without hole. For milling machine you have to choose the one with hole.

@@SteelCraft99 thanks, I’m going to search this. If i have any questions I will ask okay. Is it how much it cost? Cause I do not know how the name. I want build this machine like you too.

@@mr.ranyhomemade2466 spindle itself should cost around 50 USD and you need sleeve with spline for mounting pulley. It costs around 20USD. It's the cheepest reasonable option. If you have more questions feel free to Ask. You can also write me an email: [email protected]
