General Tormek Questions / Re: BGM-100
« Last post by RickKrung on Today at 04:30:06 am »
I find this curious, that the BGM-100 would be described as only being usable with certain jigs.  Maybe I was lucky and didn't know about this constraint.  I have used BGM-100s, or at least the Horizontal Base (HB) and the USB that comes as part of the package with every jig that I have, knives, drill bits, chisels, etc. on bench grinders with grinding wheels and paper wheels and on a Viel belt sander.  I've use wood blocks for mounting the HB and on my bench grinder/honing motor, I have them set up for use the the "FVB" (frontal vertical base), which is another implementation of using the HB and USB.

General Tormek Questions / Re: BGM-100

John,

The BGM-100 is useful for these purposes:
  • getting started with the Tormek method - you can buy the jigs before getting a Tormek grinder,
  • shaping tools where the steel is quite hard and a lot of steel removal is needed, and
  • to hold a better platform (the SVD-110) for grinding tools where high speed grinding makes sense (e.g., tools with carbide inserts).

Hope that helps.

Kind regards,
Rich

Rick,

My intended use for theNorton 3X wheels is occasional heavier grinding, specifically reshaping turning tools. For a lot of heavier routine grinding, a diamond or CBN wheel would work better. For fifty bucks, a 3X wheel adds a lot of firepower to the T4. As Rick has learned, the 3X also works with the larger size Tormeks. My plan is to use the 3X for the heavy work and finish with the SG.

The BGM-100 was designed for and is marketed as a way to quickly reshape woodturning tools, which are mostly high speed steel these days, and won't be ruined by overheating on a bench grinder. I don't think plane blades are HSS, and would be quickly damaged on a bench grinder.

General Tormek Questions / BGM-100
« Last post by jtrojohn on Yesterday at 09:38:55 pm »
I bought a BGM-100 to be able to quickly reshape a chisel or planer blade on my bench grinder before finishing it on my Tormek.  The BGM-100 manual only lists "Gouge Jig SVD-186", "Multi Jug SVS-50", and "Tool Rest SVD-110" as jigs to be used on the BGM-100.  Is there some reason I can't use chisel jig "SE-77" on the BGM-100?  If I can't then I'll have to return the BGM-100.

Also, be forewarned: the selling point of a BGM-100 is that you can use it to reshape a tool on your grinder and then duplicate the angle going from the grinder wheel to the Tormek.  However, to duplicate the angle requires the "Turning Tool Setter TTS-100" guide.  Without this guide, it is virtually impossible to duplicate the angle.  Much to my surprise the TTS-100 does not come with the BGM-100.  You have to buy it, and it's another $34. No where did I see this mentioned in any videos or documentation.  Very poor product marketing by Tormek.

I have purchased 80grit CBN wheel from KnifeGrinders and this outperforms everything else I have tried on the Tormek.
It's still not the fastest machine, but you get all the benefits of the Tormek and it's acceptable fast.

But I want to invest in a belt grinder, but it's not just for knife sharpening.

I'm very intrigued by this, Jan.  Please keep us posted.  80 grit is the same as the Norton wheel I found to be very effective in its metal removal, the primary difference being the Norton loses diameter with use.  My assumption here being CBN, they not, like the diamond wheels, loose diameter with use.

I have found that the Tormek and a belt grinder complement each other very well, especially if the belt grinder is converted to variable speed.

I am impressed with the Knife Grinders CBN wheels. However, they are only available in 250 mm diameter.
Other 200 mm CBN wheels are available. If the DWC-200 is not fast cutting enough for your needs or wants, I suggest the Norton 3X wheels, either in 80 or 46 grit. Either of these $50 wheels will get the job done for you.  The 3X wheels are not exactly plug and play with the Tormek, however, either of them will do what you need.

Ken

One Norton 3X wheel will be lots cheaper than a good quality belt sander, or the 80 grit CBN wheel. For the price, this would be hard to beat and it preserves the benefits of the Tormek wet system.  This was exactly my second attempt/option.  In fact, the Norton 3X wheels that I have actually came from Ken.  Thanks, Ken. I don't use them much any more, but the 80 grit one goes with me whenever I travel.  If I was really cramped for space, I would not take the belt grinder, instead, I'd take the Norton.

Scissors Sharpening / Re-riveting old moustache scissors
« Last post by Jan on Yesterday at 05:11:59 pm »
Recently I was sharpening old moustache scissors. The factual value of the scissors is quite low but the emotional value is high because it was used by my father and grandfather.
The blades had large play and wobbled. Rivet tightening did not solve the problem and so I decided to replace the rivet.

After de-riveting it was easier to mount the very narrow blades in the Tormek scissors jig and sharpen them.

Steel rivets with suitable cylindrical heads are not available at hardware store and so I was forced to make my own rivet. But how to do it without a mini lathe? I used metric bolt M3, mounted it into my Proxxon grinder and gently touched the grindstone of the bench grinder. See the picture. After three attempts the bolt head was reduced to a suitable size. After tightly riveting the scissors work fine again.
