Knife Sharpening / Re: Bowie Knife
July 13, 2019, 01:16:34 AM
Gentlemen, I do not have as much experience, possibilities or resources as many of you, but I have been using my tormek T-8 for more than a year and many years in sharpening with different methods, and I have had to sharpen knives of more than 2.5mm. thickness that I understand is the standard groor of a kitchen knife, for which the tormek plates for long and medium knives were destined.

I can not buy a replacement template so easily, I live in South America, and that would involve at least 20 days of waiting, higher extra shipping costs, and I can not afford to try to engineer my jig and take the risk of it going bad.

So in my case I did something that took only 2 more seconds when I sharpened both sides of a 4, 5, or 6 mm thick knife.

This is what I usually do:
If for example I'm going to draw a 20 dps edge, with the tormek turned off, I measure any of the 2 faces of the knife mounted on my template svm-45 or svm-140 with my tormek anglemaster template at 20 degrees, and with a permanent marker fine tip, I mark a line on the stone SG-250 where the edge of the knife rests on the stone, step then, I turn the knife to the other side, that we all know that will not be touching that line, because the knife is thicker than what the jig requires, then I draw with a white permanent marker, the black paste base of the jig "the one that makes contact with the usb", and I draw on the jig another white line, so that the white line of the jig, is with the white line of the black round paste that rests on the usb, and with the help of the angle master I start to move the black paste of the jig that has contact with the usb until it re-marks the 20 degrees, and I verify that the edge is again on the black line marked on the stone, once I have these 20 degrees, I look at the distance of the white line of the paste in relation to the white line of the jig and I return to mark a new white line, that gives me an exact information of the displacement that I must do in the black jig dough wheel for that side of the knife, and I mark an arrow in the direction of the turn that I must make.

When I turn the knife to sharpen the other side, I just have to go from one white line to the other, and with a little more time I have achieved a correct angle of sharpening on each side of the knife.

it may be that all this is too obvious for many, inpractical for others, a lot of delay for some others, but someone who does not want to take risks, who wants to keep his jig tormek original or who had not thought about this possibility before, can reach him to serve this advice.

Apologies for the length of the message but I wanted to detail it as best as possible so that it is understood.

Tormek leather wheel doesn't polish the high abrasive resistant steel like CPM-S110V.

How about using alcohol or water base diamond spray on leather wheel?(PA-70 + Diamond spray)

What micron do you think would be good for?

The tormek pa-70 polishing paste should be useful even for this steel CPM-S110V, I have been able to polish even edges of ceramic knives.

I can only say that it surprises me and it seems great for those of us who like precision.

just great.
I only have one question, how much does the tool weigh?

I have a question, what is the average temperature in degrees Celsius of the city where you live?

Not having a T8 but a T7.... and it never became too hot.

But I think not the average temperature of the outside is important, it is the room temperature that counts. My old shop was fairly constant, not below 12°C in winter and not above 25°C on a very hot summer day. (~54°F - 77°F). With the new shop I have not enough experience.

Rolf

If I recall correctly, Fernando was mobile sharpening... so may have been outside.

is correct, make a sharpening on the outside, with professional kitchen knives, and after 2 hours my tormek went off, I was afraid to think that it had been damaged, and do not try to turn it on again, talk to the technical support, and I answered what I have already commented, but I must also say, that once the tormek was cold, it turned on and operated normally, after that, I have continued using it but every half hour I am touching the metal of the leather wheel, and verifying how hot it is, and I'm letting the machine rest.

I had my T8 running for more than 4 hours at a time with no issues if that helps:)
Terry

I have a question, what is the average temperature in degrees Celsius of the city where you live? I ask why when I received my new tormek t-8, after 1 month of work I did not continue my tormek turn off, after 2 hours of work, when I spoke with the technical support he said it was very rare that it happened but that the machine it goes off by itself for safety when the machine is very hot, and I think the weather can affect the machine, the weather in my city is between 25 and 33 degrees Celsius, the day my tormek went off the weather was hot.
#22
Something similar happened to me, and it may not be your case, but using my Tormek T-8 it stopped working, after a while of work, it is possible that your engine did not hurt, it just turn off for safety because was it overheating, and did you try turning it on again a couple of hours later when it was already cold?

Good reply, Kwakster and Ken.  :)

The attached graph shows, that aluminium oxide is harder than tungsten carbide but less hard than vanadium carbides.

Jan

remain with the doubt of where the carborundum is, I know that it is above the aluminum oxide but I do not know if it is harder than the vanadium carbide

Before tormek my main sharpening system was lansky, because I mainly sharpened victorinox Swiss knives with diamond stones, and when time is not a problem, lansky is an excellent option, it has a good cost - benefit, it is a good option for those little blades of folding knives, but now with tormek I think it could solve the self-centering problem, and grab small razor blades, with the improvement of speed. I like the idea
It is good to try new alternatives  :)

The question I've been asked many times, if any knife can be sharpened sharper than a razor.
This method works for steels prone to form "negative burr", and many of those in-between, as explained in our study http://knifegrinders.com.au/Manuals/Knife_Deburring.pdf
.

the subject is really interesting.
just one thing, the link to the pdf did not work for me, can you verify it?

Order received. 


Nice assortment of four sizes, 50 each.  Nice heavy card stock.  Easy to cut down.  Delivering five knives tomorrow from the last farmers market and they will be sleeved!  Put two on my own knives that live in the drawer rather than the block. 

Rick

It is a good idea to make some paper covers with our brands and contact information, so customers can have the data at hand, instead of giving a business card that they often lose.
I imagine the situation "honey, knives are dull, you know where they can send to sharpen?, - love just look at the case there are the data."

General Tormek Questions / Re: "Need Photos"

If you are talking about the "official" site as the Tormek forum, the old limit may have been four, but I recall they upped it to eight and I have loaded as many at times. 

For photo manipulation, I've been using ACDSee for around 15 yrs.  It does all sorts of stuff and is easy to use.  Yes, it does cost something.  I have PhotoShop and Lightroom but find them way too complicated for fast and easy use.  Mostly what I do for photos I want to upload is 1) Crop and 2) Resize.  Only takes seconds. 

Rick

Rick, I'm glad to know that you also use ACDSee.

I am an amateur photographer, and like you have been using ACDSee for a long time, almost 2 decades, and I would say that it is an application that effectively solves small tasks with photos in a very fast way, cut back, resize, and hundreds of quick adjustments. , how to edit metadata and work in batches, this is quite useful when you have hundreds of photos that you must change the size, all are selected, and you set the size you want, one click and only let the program do magic.

I often get replies to my posts stating "need photos". I agree, photos would help clarify things. I can make digital photos. My  bottleneck is getting them from my ipad or macbook to the forum post.

I know there are two venues for photo insertion, the official insertion program and third parties. The official program stores photos on the forum, with limits of four photos, each not larger than 250 kB. The third parties store photos off site and do not have the size and quantity limits.

I don't have a problem with the limits themselves. In fact, we lost many useful photos when Photobucket, the first third party used on this forum, went from free to $400. Four photos per post seems both reasonable and workable to me. I am willing to work at 250 kB per photo. My difficulty is reliably and easily sizing my images down to conform to the limit. I don't mind working within 250 kB if I can easily get there and not end up with images well below the 250 kB limit. I want all the image quality I can get within the program limits.

I am also willing to work with a third party app, if it works well with ios (ipad). Also working well with my macbook would be a big plus. I don't mind paying reasonable fees.

I have used the Image Size app, but with limited success.

Your thoughts would be most appreciated.

Ken

Hello Ken

Today almost everyone has an account on Google, so it should be easy that from your iphone, ipad, have google app, in the itunes store are all and are free, for example with google photos is the one I use, I can upload unlimited photos in any size and then I only have the option to share image, copy and paste in the forum of tormek and now, the configuration and use is easy and keeps private what you want private and you only share what you want.
Google drive can also serve you, and it has like 15 GB free

I hope it's useful for you.

Hi Rick,

I've detailed our sharpening of ceramic knives on our website http://knifegrinders.com.au/06Procedures_ceramic.htm

Can only add that in the Kyocera video we see them finishing ceramic knives on a felt buffer with what looks like a Green Rouge compound. Technically, chromium and aluminium oxide cannot grind ceramic, but obviously they know what they do at Kyocera.

Very good information

Although I must admit that later I went to see the good results of the repairs of the knives.  :o ;D
