Good to see you back Rus! Great video and I gotta say that making your on tools for things like that are perfect. Get-R-Done 👍

Russ, glad to see you back! I hope your cold decides to leave soon. Lots of cleverness in this video...from the pin spanner to the use of an endmill as a boring bar. The mod of the bearing puller was cool too...only advantage to cheap tools...you don't mind cutting on them when you need to! I'm still wishing for a mill, but I recently bought a used South Bend 9" lathe so I'm having fun trying out some of what I've been watching for months. It's amazing what you can learn on KZfaq. Thanks for sharing your upgrade experience...I know I'll be watching it again someday when I get that mill. -- Mike

First spindle arbour I have been able to see on YT, thanks. Of course the one I might be dealing with is from a full sized 60's vertical mill . But this just what the doctor ordered as I decide on whether to spend $500 on regrinding the B&S#9 to an R8

Glad your back. I've been thinking of sending you a message to see how your stuff was going

Thanks Rus really appreciate the explanation.

Great video Rus, my new bearings are en route and hopefully should be installed this weekend.

Wait for your next video ! Thanks you

Welcome back Russ.

Good video russ, i'm in the middle of converting my G0704 to CNC and will be doing the belt drive in the future. Once you post all the videos and work out the kinks:).

Nice use of a slot drill (end mill) for boring. Never seen that before. Will definitely be giving that a go.

I took a pair of slip joint pliers and drilled a hole in each jaw, threaded the holes 8-32 IIRC and used 2 SHCP's to engage the ring. Unscrew the screws and the pliers function as normal. The slip joints and the fact that they are pliers allows possibilities of large rings too.

NOTE! He then reverted to Tapered Bearings

Nice video man!

Great video!

thank you for the excellent video.

just place the quill/spindle assembly in the vise. next use the spindle lock tool and a hammer. place the tool in the pin holes (not the threaded holes) on washer nuts and lightly tap with a hammer counter clockwise

Thanks for the video Rus. Could you explain preload a little more. I am somewhat confused as to what it is and when it should be used.

Cool, thanks Russ. I just did this upgrade a few weeks back. Interesting that your retaining nuts were on there so tight, Mine came off pretty easily. My mill i only 3 months old, so maybe they tighten up with time? Yea, it was painful for me to order that Kluber grease also, and I used a similar serenge/needle setup. Looking forward to your next video...

I have found with standard 3-jaw pullers that a more expensive one may not necessarily work better...

Russ, I'm in the process of replacing the bearing on a Okamoto surface grinder. YES, it does have a big effect on how much lubricant you use on bearings. While it may not have very much effect on the stock machine it will when you keep upping the RPM's such as you stated. Do yourself a favor and do some research. It's different for each type of bearing, size, speed, and load. Good luck.

Hi Russ- I broke-down my spindle today and found that your video was spot on. I did make a pin spinner per your pictures. Never did find your drawing, but got concept and made it using 9/16 round stock, worked like a champ. I wanted to ask you if you, or anyone else has figured out a way to grease these spindle bearings? When I disassembled I found grease everywhere inside the spindle, except for on the bearings.. my machine is only about a year and a half old, but bottom bearing was really getting hot even running with no load. But I can sure se why now that I found it bone dry. I am really surprised that it didn't seize. Thanks for the video Howard

If you need a pin spanner just drill 2 holes in the end of a piece of thick walled scrap DOM pipe then insert some steel spin stock than slide that over the spindle shaft and turn the nut out.

Like the tool, tryed to make the same but with screws, seems that the cup is pretty tight to unscrew ti with a bolt, all bolt's bended and i will try to turn some tool, did you use mild steel for the pind or something else?

I don't mean to sound like a familiar broken record, but studies have demonstrated that vitamin C does significantly reduce the length of colds, in many cases as much as half. It's always worth it to make sure you get a good dose of it every day while you have a cold.

The preload specs are in your manual you should have got with the machine.

where did you find the bearing lubrication amount specs? I got the same bearing from VXB, and I can't find a grease quantity anywhere

Pretty sure they used a screw to index the collet, so that when you eventually manage to jam it up there hard and break it off... you can at least repair it instead of replacing it! :)

I do really think the original's luck more robust than those angular bearings. Do someone run spec in the originals vs these Nachi.

why did you change out the taper bearing for a roller bearing on the mill shaft ? they use a taper bearing on the work end of the shaft so the side play can be taken out through bearing load adjustment. I don't understand why you changed this ? any side play you have or develope over time from wear you now cannot remove because the taper bearing is on the wrong end of the shaft.

hi i want to make spindle and drow bar to my homemade mill machine can you tell me the size of spindle ..bearing ..drow bar thread ets or if you have plan or Sketch to make the mill head ?? thanks
