Making a Toolpost Grinder Part 20: Wheel Arbor 3

[@paulmorrow5905]

i am binge watching this series. an all day affair it seems.. lol

[@BillySugger1965]

Man, that is sweet! I’m surprised that you didn’t run an indicator on that wheel journal before launch though, unless you did off camera. Nice work James! 👏

[@sto2779]

47:17 - Nice. I'll follow your vid to make high speed spindle.

[@liampollard2908]

12:20 (and other timews): you need a HSS - high speed Sharpie!)

[@mighi68]

I like that grinder ...

[@exoskillet4409]

Very nice series! Well done!

[@Clough42]

Thank you!

[@greybeard3759]

Excellent! That is a well done project.

[@Clough42]

Thank you!

[@bostondan77]

Looking good.

[@Clough42]

Thanks!

[@sharpx777]

this is a great project, i've been following all the vids in this series and can't wait to see the next one. would be interesting to see what runout you have on the arbor when mounted in the spindle (very low by the looks of it). Thanks for sharing.

[@Clough42]

It is very low. A few tenths. I thought I got that on video, but apparently I missed it.

[@somebodyelse6673]

Looks good so far. Are you considering lead screw and way covers before you become a toolpost grinder addict? Given how well designed your projects thus far have been, I'd like to see what you came up with to keep your lathe safe from preventable wear.

[@Clough42]

That's a great idea. The current plan is to use towels and Pig Mat. I'm also hoping that using coolant while grinding will make the grit land and stick instead of flying all over the lathe.

[@christianstark1055]

I bet you could really dial that taper in if you had a tool post grinder... ;-p. Loving the series.

[@emo1net]

Nice series! I'm noticing something over and over in your videos and that's probably because I'm currently addressing the same issue on my lathe which is the same as yours. You are getting huge tool-post deflection like at 21:33 and it looks like it may be time for another project like substituting that compound with a solid block of steel and adding 4 more holes. As I said earlier, I'm currently doing this to my lathe and I noticed something else. Clamping down the compound with the 2 bolts actually bends my table and changes the pressure on the gibs by a lot because the bolts are pulling up on wither side while the compound centering post is pushing down in the middle. Look into this if you care and I think you will find great improvements in how rigid you lathe is. If you haven't heard of this very popular mod ( which I doubt, to be honest ), just search of "grizzly g0602 solid tool post". Take care.

[@Clough42]

Yeah, I know it's an issue with this lathe, but I hadn't realized how bad it was until I saw that clip in this video. The tool was really diving into the work there. A compound upgrade is on my list of projects; I just haven't gotten to it yet. I'd really like to get rid of the compound entirely and replace it with a solid block, but I use the compound quite a bit for threading and tapering. I'd also like to make a taper attachment, and I'll need the compound on the lathe for that, since the cross-feed is disconnected. One project at a time, I guess. :)

[@Neptune730]

Nice. I would have started with the taper first myself.

[@TheDuerden]

I have now watched the first 20 parts, and still not really sure what this tool is supposed to do, I am guessing grind things in the lathe but will be interesting to see it in action - which brings me to the thought - hold on, I have watched an absolute mountain of James' content....why have I never seen this tool before? What happened to it?

[@danieltompkins400]

Mr Clough, thoroughly enjoying this series of videos and you have apparently inspired me to build my own. Are you going to make your drawing available?

[@Clough42]

Yes. The drawings will be available soon. I wanted to get through the project and find all the mistakes first. :)

[@fpreston9527]

Nice work

[@Clough42]

Thanks!

[@dannypeto8734]

is that a Grizzly lath ? seems to run pretty good.

[@PaulMorley1]

Hi James. Any chance you have a link to where you got the 'Powerbuilt CR-V 22MM offset wrench for the top of the toolpost? I've spent more time than I care to admit searching for that and i'm starting to think you've done some magical CG work to add it to your videos as I can't find it anywhere. ;-) . Much appreciated and love the content.

[@Clough42]

It's a normal combination wrench that had a run-in with a cut-off wheel, a torch, and a vise.

[@joer8486]

Great work! I'm trying to make my way through all of your videos. I love the way you explain your actions as you show them. I have a couple of questions: I'm interested in the copper you are using here - and for your lathe jaws on the 4-jaw chuck. Do you get it in sheet or roll? What is the thickness? Is it soft copper? Where can I buy it?

[@Clough42]

It's .025" copper sheet. I bought it at Hobby Lobby and cut it to shape with a small shear and tin snips. If you have a store near you, they almost always have a 40% off coupon on their web site. www.hobbylobby.com/Crafts-Hobbies/Hobbies-Collecting/Tools-Blades/Copper-Sheet---025/p/21779

[@DSCKy]

You could probably use your collet as a wrench...

[@Clough42]

Yeah, you have a good point. As long as it's tight enough that it doesn't slip. I'd hate to gall up the taper.

[@Asaadomar]

If i were you i would make more than one wheel arbor at the same setup

[@Clough42]

I totally agree--especially the taper setup. I was trying to get the video done. I'll probably make a batch of them later.
