I get so nervous when you describe things with your hand moving it "close" to your spinning wheel. Please be very careful considering the unrepairable damage such a wheel could do on your hand. I enjoy your videos very much and am in current work building a 200m2 hobby fun shop myself.
Yes, I bumped my camera and it was on the wrong setting. Could not see it so well in the viewfinder of the camera but it was obvious when I started editing. Very frustrating....
Welcome to the DIY channel; why not it is a machine shop! And, you do fine work. We call bricklayers "meticulous arrangers of artistic burnt clay products" so you and some others are "meticulous machiners of artistic metal products"! So there, Greg.
Keith, How are you and yours?,Hope this finds you OK. i know its to late but couldn't you mill clearance groves in the bottom of your fence? wouldn't that allow coolant to drain away?and not affect your already ground tolerance?
Because wheels aren't straight up and down, square, or even round. You always dress to the shape you need. If he hadn't dressed the wheel putting a negative clearance on the backside, he likely would have ground an angle on the fence as well as only been contacting part of the wheel through some of the grind. That puts the wheel in a bind and that can crack a wheel.
I think the question is valid though. if you use the wheel as is, the sides are going to be pretty parallel - across the thickness of that bit of angle iron, the degree of square would be excellent. without dressing, the worst that would happen is that the wheel would only be making contact at the highest spot of its rotation. the resulting grind on the work would be the same. and if the wheel wears that fast, it would rapidly wear itself to a consistent state.
would an indicator have helped with the cross slide adjustment? And after deburring with file would it have benefitted from running the wheel down the rail again in case you pushed a burr over the edge filing? Great video as always! Cheers!
I don't understand what the dovetail on the nose fitting of the dressing tool is for. If the rod only allows one position, why have a dovetail? Looking at it, if you flip the nose piece over, does the rod set it to be concentric? Maybe the rod is for a centered position and the set screw is for any other position? Disclaimer, I am not a machinist and I don't even play one on TV.
That was the whole purpose of dressing the wheel to a slight angle - so that you make full contact on only one edge to prevent a bevel. No, it is square.
Hey buddy check out a product called kool-mist thats what I have on mine love it I got mine at a auction so I don't know what the total cost would be But I love mine part don't get that hot with it
I am probably going to invest in one of the Noga mist systems for this machine. I have a cool-mist I use on my mill sometimes but it gives me a lot of problems.
Great information. Thanks for sharing. Could you just mill some channels for the coolant to escape, or make them large enough and you will have the bosses....?
We have a new Okamoto 12x24. I put the rails on the back but it never occurred to me to side wheel it. Never use it for precision work but I'll soon be able to! Thanks for the idea.
Agreed. Everything about this video seems 'hot' Might be some static on the audio as well. Perhaps a connection not seated or signs of impending trouble down the road.
Yeah, I did not catch it when I was shooting but my camera got bumped to a different setting than I usually use. Tough to figure that out once you start editing.
I said the same thing to the guys at a meeting of the Home Metal Shop Club here in Houston. They told me I should get a full face shield... especially with grinders on account of those wheels have been known to disintegrate... explosively. I'm a novice so I just take their word for things.
A busy guy goes out of his way to make a video that you enjoy for free and THAT is your comment? Do you actually think that he needs you to remind him to wear his glasses? Unbelievable.

When you were dressing the wheel the second time could you have just dressed the wheel at the bottom to get a sharp edge back rather then redress the side of the wheel?
Flood coolant will be a great addition to your machine !
I agree! I plan to purchase at least a mist system for it.
Thanks Keath
9:25 if that is a light pass hate to see a heavy one from you Keith!
LOL - Side wheeling seems to make a lot more sparks! That and the fact that I don't have a fine adjust going in and out on this machine.
Listen who's talking with a 75 foot long boring rig. Just hang it and go for oil! That'd make Baily wagg!
A Getter Done with a southern accent; LOVE IT.
Better find or make the missing section of your way cover.
I really hope you could wait for the wheel to stop before you stick your hand in. Stay safe.

Is there some reason you have not been using flood coolant while grinding?
Yes, I don't have any coolant on this machine right now. I will be adding it in the near future.
Dose this machine have coolant?
It did at one time but not working now. That is something I need to add back on. At least a cool-mist system is in my future.
Thanks for the answer. Be safe.
Dear Keith Please keep your fingers/hand at a safer distance from the spinning grinding wheel !
Something odd with your white balance on this one.

Why on earth go to so much trouble?
What's the issue with just using the wheel as-is?
Because wheels aren't straight up and down, square, or even round. You always dress to the shape you need. If he hadn't dressed the wheel putting a negative clearance on the backside, he likely would have ground an angle on the fence as well as only been contacting part of the wheel through some of the grind.

The dressing tool looks like a prop out of a James Bond movie. But in good hands it does nice work.
It is for making fine adjustments to the center height of the diamond.
A good surface grinder back rail fence is a basic must have, so $75 is a very good investment.
THANK YOU...for sharing.
is there a difference between "conventional" grinding and "climb" grinding?
funny to see rookie grinders, not to say I'm a pro, cause I'm a rookie too, but glad to see someone else burn the rail. great videos keith
You dress the wheel to reduce contact area while grinding the rail, to reduce heat buildup and warpage
another great video Thanks Keith
did you indicate the back plate afterwards?
At 4:04 Why not drill and tap a hole somewhere on the Equipment for the guard not to lose it in action?
I am a little confused. If you grind a 1 degree taper on the back of the wheel, would you not then grind a 1 degree angle on the fence??
No, because the wheel is round so the outside edge covers the entire face when you are side wheel grinding.
Keith, why didn't you keep raising the wheel after making multiple passes? I think you may have ground a beveled edge on your fence...
That was the whole purpose of dressing the wheel to a slight angle - so that you make full contact on only one edge to prevent a bevel. No, it is square.
can't seem to get those decimal charts,is that the right email
Always good Keith thanks for sharing
Hi Keith... Is it necessary to compensate for grinding wheel wear when levelling a large surface?
The best thing to do in that situation is to rough grind everything and at the end, put a fresh dress on the wheel and finish with a very light pass.

Great work Keith.
Great information. Thanks for sharing. Could you just mill some channels for the coolant to escape, or make them large enough and you will have the bosses....?
One question: Would it have been useful to grind the surface/Contact area between fence and the machine, if you take the fence on and off?
probably when he gets the proper fence, a machined face will be a good idea
new and old tech Its common practice to re-grind the backrail everytime you take it off and put it back on

White balance seems to be off in this vid,and your audio was clipping a little bit. Other then than, another great video!
looks way over exposed then adjusted back down with contrast

Great video: I learned a lot. Would like to ask for one small favor. Suppose you could wear some eye protection?
I DO! THOSE ARE GLASSES HANGING OFF THE END OF MY NOSE!

Kieth, what is the address of the museum you work at? Myself and my friends would like to go there.

Kevin, look up the Georgia Museum of Agriculture. They have a nice web site.
I love it when people answer my questions. Saves me the trouble! Thanks!
Great video * we'll get to see the fence grind again "by golly!
Cool video, I learn alot! Thanks Keith and Thanks Stan!!
When you were dressing the wheel the second time could you have just dressed the wheel at the bottom to get a sharp edge back rather then redress the side of the wheel?
I would of love to have a tool like that back when I was working in the tool room.
Nice work, Keith!
I would love to see a resto of this machine, i really enjoyed that series.
