Hey Walter, thanks to you for mentioning combat abrasives over the years, once I switched to them I can run my grinder at turtle speed and still destroy steel in seconds! Abrasives are super important !
Very informative, Thanks! I have a bucket full of mild steel "blades" that I used to learn grind speed and grind angle for any given piece. I still use mild steel tests almost every time I try a new shape or size. I make tools a lot more than I make blades, so I haven't done enough of any one type to get good at it.
very good video. have a q? sir for ceramic knife sharpening what kind of belt i need and from where to buy i have 2x72 and 1x30 grinder ......God bless you sir.....
Hey Walter, any tips for how to grind handle pins down so they are flush with the handle material? I have a tendency to sand down the wood much quicker and feel the pins raised a bit
I use a rubber wheel instead of a flat platten. You have to be very careful to only hit the pins themselves. Once you get close I do 1 or 2 passes over the entire surface of the handle material to bring it down evenly. That's what I do but whatever works for you
If you can only have one speed or 1ph motor what rpm should I get I have a 7in wheel i was thinking of getting smaller wheels to slow down the motor like a 4
I was the same way for a long time. I ran it wide open on 1 speed approx 5,500. Then I changed it to a step pulley system. Was very cheap and works great. 5 settings Slowest 1,800sfpm fastest 8400sfpm.
I switched to a DC treadmill motor. 2 1/2 hp. I run it off a Variac transformer. An in line bridge rectifier changes the AC to DC. Turning the knob on the transformer gives infinite speed control. Got the motor for free. The transformer was 100 bucks new, and a dozen bridge rectifiers were $6.80 on Ebay. You only need one There's a bunch of videos on TH-cam on this for anyone interested in finally making a variable speed grinder that works. Been running mine for a year and a half with no issues, and I'm not an electrician. ✌
Did something similar myself at first. Worked great for a while but those dc treadmill motors eventually get fried from sucking in too much metal dust. Do what you can to mitigate metal dust in the air around the motor and controller so you delay the inevitable even longer than you already have.
In the current political climate it is Quite refreshing to hear the word GRINDER & know it is not a empty parking lot with shaven headed young men singing catchy sayings-Walt you are amazing,
12 to 15 hundred dollars is a lot (for most) ..that's why I''ve been gathering the parts needed for one this past year. I'm only missing a couple of minor things so I think I'm gonna be able to assemble it in the next month or two ...I just wanna share my excitement about it here, haven't been looking forward to something this much since I was a kid :)
I've been making knives for a couple of years and I use the Harbor Freight one by 30 which was good but had a fixed speed. I then researched how to make a 2X72 welded it together ordered the wheels and put a treadmill motor with variable speed and it was a game changer variable speed is one of the most useful aspect of having a 2x72 grinder it is not the most powerful set up but I'm not trying to go fast when I go fast I make big mistakes when I slow the belt down any mistake are small and easier to fix. Saying that when I am grinding on wood I slow it down so as not to burn the wood especially with finer grit belts the finer the grit the hotter they get. Just my two cents from an old man in Tucson.
I really want to and try to watch your videos- they are really informative. However, I can’t get past the way you record yourself. I’ve tried speeding up the videos but it just makes it worse. I’m going to try and record them on my iPhone and see if can use slow mode or some sort of video sound filter. Maybe you try talking with food in your mouth or try using a British accent? Any how thanks for the videos- I think? Yes I can spell worth shet.
"Don't necesarrily do as I do". LOL, If I could do as you do, I wouldn't be watching this. You are the master. Thanks for the content.
Walter..thank you for all the time you put into these great videos..you have helped me so much. Merry Christmas my friend
Hey Walter, thanks to you for mentioning combat abrasives over the years, once I switched to them I can run my grinder at turtle speed and still destroy steel in seconds! Abrasives are super important !
One thing I've learned is that the faster I run my grinder, the deeper my grind mistakes are, and the harder they are to recover from.
Me too.
Very informative, Thanks! I have a bucket full of mild steel "blades" that I used to learn grind speed and grind angle for any given piece.

Walter always manages to politely remind us that success or failure has less to do with our tools and more to do with our mastery over them.
Thank you for this video, I had to learn what you said by trial and error.
Merry Christmas 🌲🎄🎁❄️
You the man
The master!at it again 👍

Great video...great advice 👍

very interesting video!thanks
what would yu charge to make me a vise attach to my 1x30 grinder. I saw youu make one in your fabrication shop.

@@RibeyeReaper Thanks for the heads up. I'll try to box and filter that motor. 👍
My rule on this:
Does whatever I grind burn (easily)?
If yes: slower
If no: faster
Hi my 2"×72" is a fixed speed grinder I did not know when bought how hard to retro fit this. Can you electronically add to this
Yes, you can add a variable speed controller between power outlet and drive motor.
@@MJFacas thank you need to find a electrician that knows what he is doing
Sundays are the new fridays
Seconds of rushing screws up hours of hard work.
I sometimes dont know at what speed i should drill, 10rpm make quite a differrence sometimes
I just run mine until the thing smokes and I can't touch the work anymore. 🙃

The problem is most of us can’t afford those big dollar grinders

I got a 2x42 it works good but it’s slow grinding
Why do you sound so nazzle?
Wow I don't think that's a concern for a master sharing his skillet. Friend, who made you the video police anyway?
And as far as that goes why can't you spell nasal?
