Update 1.11.17

TLDR: If you ever thought about trying paper wheels (Razor Sharp Edgemaking System), DO IT. Less then $150 in this setup. Quiet enough for apartment. Awesome sharp polished edges fast.


My paper wheels arrived today and off to Lowes I went to pick up the grinder listed below.


Also want to add that I live in an apartment and this motor and setup is quiet enough to not bother the neighbors.


This Delta grinder was very easy to flip the motor around on and take the guards off. This will not be its home obviously I think my lady would be upset haha. I should have taken more pics but I was like a kid on Xmas :D




Quick Review: Where has this been all my life?!!?

I have freehanded for awhile and have a Wicked Edge system. Before I dropped anymore money on stones for the Wicked Edge I wanted to try paper wheels. I used a sharpie to cover the edge and went at it with a big grin.

First knife I tried was my Spyderco Salt. Its a user and well loved. You can see I was a bit low at the back but that wiped off. ( I should have wiped it off first but I was shocked that just a few passes brought out sweet shine.)




Next up my Izula. Another loved knife.









Overall I am very happy. These 2 knives were done with 15 minutes experience after just getting this all setup today. I am sure with more practice the results will be better. Now its time to tackle the kitchen knife that my lovely lady likes to use on paper plates with granite counter under it. :eek::yawn::D It will live again!!









******************************************************************************************************************

Hi all, I am going to order the Razor Sharp Edgemaking system in the 8 inch size and I need to pick up an appropriate grinder to put them on.

I did go through Richards thread but the links to the recommended grinders where no longer working or product unavailable anymore.


I know he uses a .5 hp motor at 1750 rpm and that a 6in Porter Cable variable speed grinder was recommended but link said not available.


I found a Delta Variable Speed Bench Grinder for about $80 at a home improvement store. RPMs vary from 2000-3400 so this is close to what Richard recommended.

I do not see a horsepower rating but it does operate at 2.5 amps.


Link below to Delta model number 23-196

Will this work well for the paper wheel system?

I would like to get the wheels ordered soon but want to make sure I will have a grinder to put them on. If it is not a good one, please recommend me one for the 8in wheel system.

Thanks a lot guys and big thanks to Richard for all the time and effort in that huge thread. Maybe we can get it updated with more models that are available now.

That should work... looks similar to a Craftsman I have (in the background of the below picture), and it's only a 2.0 amp.

Best thing I ever found to run the wheels on though, was a 6" buffer w/ 8" wheels (in the foreground). The reason... you get more clearance between the wheels for longer knives. But I'm also in the camp that believes the wheels should be run faster, and not the 1750 rpm that Richard suggests. For me, they run smoother and actually cooler at the higher speed. (It's also what the manufacturer recommends).

(I now have the back one set up with thinner wheels for serrations).

Probably goes without saying, but either way, practice on 'cheapie' knives first! :thumbup:
 
Thanks for the input. I also saw a few 6in buffers for not too much and the extra clearance would be nice. I was hoping the Delta variable would let me use the wheels at the full recommended speed and try it out slower like Richard to see what works best for me. I will def start out with cheapo knives.
 
The Delta will be fine for your needs.
A 6" wheel will run at a lower surface speed than an 8" wheel.
 
I agree with higher speed. For me, the wheels run truer using a cheap grinder at higher speed, than a better quality grinder at slow speed.
 
I use the Delta that you posted above it works good at about 3/4 speed. Also it was easy to turn the motor around on the base
so now I can use the top of the wheel spinning away from you. For me it is easier to see what your doing that way too.
 
Wheels don't run truer at high speed. All high speed does is make the high spots move faster.
Wheels should be trued before use, if possible.
 
I notice less vibration at higher speed and the blade has less tendancy to bounce.

I'm not sure if this is because the cardboard is a semi-flexible material, but it's the opposite of what you'd expect. If a car or bike has wheels that are out of true, the effect is magnified at greater speed.

Anyway, I get better results at the manufacturers' recommended speed, and I guess that's why they recommend it.

Can I ask, how did you adapt the buffer to take the wheels? You've removed the tapered spindles and replaced them with ..?

Don't get 6" wheels... you won't have enough clearance of the grinder/buffer housing to manipulate some knives. 8" is a "better fit" for this purpose.

Whatever the reason, for me they work better at the higher speed. :rolleyes:

No mod needed... this didn't come with tapered spindles. (None I've seen searching around this a.m. appear to either? :confused: ).
 
The delta 6in variabl speed grinder is what I use. Only down side is it gets hot with prolonged use, it's never shut down or had any other issues but sometime I can be using it for up to an hour and the body gets pretty hot to the touch. Besides that, It has good speed control and runs smooth and quiet.
 
Updated original post with pics of setup and mini review. Thank you all for the input and help. I am very pleased with it.
