❤ an essential piece of kit along with a glass lapping plate 😊 3in1 works for me ! The smell is most nostalgic! 😊
I totally agree!
3 in 1 oil works, generally most light oils will work for sanding/grinding, though dedicated cutting oils like Tap Magic will work better since they're specifically for cutting.
Tap Magic also smells good too, that's how you know it's a quality product. :p
Thanks for the info!
I believe the sharpening station is the box. You close it and put the stone on top and there you have it.
Just what I intended to say! 5:39 clearly shows the plastic lugs that hold the stone in place, though you are better making off making something out of plywood because the boxes tend to flex and develop cracks.
Exactly. The box has rubber feet to hold the box from moving around. And the top of the lid has little guardrails in the corners to retain the stone from slipping off the box. 👍👍
When I was doing my carpentry apprenticeship 50 years ago I was told any light mineral oil will do, but most carpenters carry 3 in 1 oil anyway. I found that a squirt of WD40 does a good job as well. Having it in a plastic box will be useful as once the stone matures it will be saturated in oil and in the olde days oil stones were kept in home made wooden boxes and they too become saturated in oil leaving an oil mark on any wooden surface, like a carpenters bench. Many oil stones come double sided a fine and medium. Modern times have updated tool sharpening and now-a-days I use diamond stones which use water as the lubricant and come in multiple grades even up to 1200 for very fine finishes.
Thanks for the info, I think that I will also buy a Diamond stone too }:-)))
I inherited an India stone from my father, sadly I dropped it on a concrete floor and it broke! I got another from Lidle, and its great!
Can this be used for cleaning port faces?
Yes you can, that is the main reason I bought the stone.
@keithappleton Thank you. I'm currently rebuilding a 5" gauge sweet pea, and your channel has been a massive help. Keep up the good work 👍
Much more coming up shortly }:-)))
Keith I think that the "Mini Sharpening Station" mentioned on the plastic box is the plastic box itself. Notice that the top of it has a couple of plastic bits that stick out and form a rectangle. I think the idea is that you put the stone on top of the box, inside of the rectangle and the rubber feet on the bottom of the box will it hold the whole setup steady while you use it.
To clean the stone use a piece of cork from a bottle of wine...and you get to drink the wine too...bonus
Good Idea - Cheers }:-)))
Any light oil will work. WD-40 works great as does the oil you are using. I am a millwright/machinist, and I stone surfaces on a regular basis.
Thank you, it is encouraging to know that i am doing it right }:-)))
Even better are stones which have been ground flat. Normally used as a pair so that they can be rubbed together to clean and keep flat. They are ideal for use on machinery as they will not cut a flat surface but they will remove the tiniest of dings. If you have a friend with a surface grinder they can be easily made.
Diamond stones are also extremely useful for de-burring operations.
Doing figure eights is the way to properly lap parts but my preference is to go back and forth at 45 degrees and then rotate the part 90 for a couple strokes to make a nice fine cross hatch pattern.
If your stone becomes clogged, dull or warn uneven you can refresh it like new by lapping it with light pressure in figure eights on a piece of glass or polished granite with some medium valve grinding compound from the auto parts store. I do this to my 30÷ year old Norton stone every few years using a slab of hardened ground tool steel I have.
You can also use stones on the lathe like a file if you need to shave a few tenths of a part. There's many types used in the tool making trade which are very handy.
I use a stone to “polish” tool blocks flat that mate with the turret on CNC lathes where I work. The youngsters tend to tighten the tool blocks down with tiny swarf chips between them, thus embedding them into the blocks. Then they comment that they don’t understand why the tools are chattering…
I think the stone I use is an “Arkansas” stone. It’s a very fine grade. Made in the USA is probably the plastic box…
Thanks for sharing this very informative video with us. You also stay safe and extremely healthy for a long, long time!
The plastic box is the worst bit, this one arrived with a crack in it . . . .
I'm guessing the "mini sharpening station" refers to the box it came in. Hope you didn't pay extra for it !
No it was free }:--)))
Mexico is the 51st state of the United States. 🤣
