New MB-102 Multibase

[Ken S]

Realistically, I think mid October is an optimistic best guess, at least in the US. I suggest contacting your dealer and asking about pre ordering.

I understand your frustration.

Not really. Actually happy with what I have. No use *really* crying over spilt milk

Plus you can use your MB-100 in conjunction with your FVB! Yay!

Just an afterthought : I am curious as to how the squareness of the MB-102 relative to the wheel axis will be ensured when using it as a FVB... It seems about as important when grinding edge trailing as it is edge-leading.

Today the USB is made vertical (the way I understand it) by pressing down on top of the support leg with the MicroAdjust nut. As there is no MicroAdjust nut on the MB-102, how will it be done ? The currrent FVB implementations with a solid block of metal use the casing as a reference. Maybe using the legs of the USB when mounted in the MB-102 ? Might be easier with the taller US-430 ? I see no reference to this in the manual...

Any thoughts ?

Based on the clip of the upcoming class, it looks like they're doing what you suggested...

Let's examine this thread piece by piece.

It is unfortunate financially for anyone who already has a MB-100 or an FVB. For anyone who "just" ordered either, it is possible that the transaction may be in a return allowable time period. If not, either the MB-100 or the FVB is just as functionable as when purchased. They can still work as desired or can probably be sold for close to new price.

In my opinion, the design of the MB-102 is very clever. It combines two functions for approximately the cost of either one. I would choose he MB-102 over purchasing either of the single function tools. For no more than the cost of either single function tools, you can get both in one tool. It seems like future need protection for no extra cost.

I don't understand the technical questions about alignment accuracy. I do have faith that Tormek would not release any new products without extensive testing and a solid belief that the product would perform as designed. I hold Tormek in very high regard, although I do not give them a free pass.

I will withhold my final opinion about the MB-102 until after I have an extensive chance to use it.

I don't understand the technical questions about alignment accuracy.

Well if you look at the pic in @cbwx34's post, that should help. It looks like the legs of the USB are used to ensure proper alignment.

Now I apologize if my poor mastery of english implied that I was saying the FVB-102 would be hard to align properly. English is a second language to me. I was merely stating two facts : No MicroAdjust nut (so it won't align the same way the USB does) and no indication on how to align it in the manual (as far as I could see).

I think the (many) technical questions in this forum have also been useful to Tormek and have allowed them to improve their products, as exemplified precisely by this MB-102. If accuracy wasn't a fair question to ask, there would be no need for extra holes in the MB-102 or for a new angle setting tool, or probably for a jig altogether.

Unlike the vertical position, I think gravity will pretty much center/align the horizontal position, will it not?  I don't see any issue with the current MB-100, so a need to have instructions isn't necessary, as far as I can tell anyway.  The vertical support needs it because it can rock back and forth (and in reality it's more for some woodworking tools, not really needed for knives.)

In fact, having the vertical support rub against the machine... probably not ideal, it could cause the vertical support to "hang", tilt, etc.

TGB,

I look at the technical questions on this forum the same way I look at the space program. I have no plans to go into space; however, I believe the knowledge we have gained from the space program has benefitted the car I drive. My humble kenjig has most certainly benefitted from the earlier forum questioning of Dutchman's grinding tables. I still do not fully understand Dutchman's math, although I have learned enough to have faith in it. We have all benefited from Dutchman's pioneering work, as I believe we will from today's technical questions. I may not fully understand them; however, that does not mean that I do not see value for all of us in them.

I was referring to the misalignment that could have occured if the distance to the horizontal sleeves along one of the legs was different from that along the other leg.

I don't see any issue with the current MB-100, so a need to have instructions isn't necessary, as far as I can tell anyway.  The vertical support needs it because it can rock back and forth (and in reality it's more for some woodworking tools, not really needed for knives.)

The way I understood it (and that might be completely wrong) is that pressing down on the MicroAdjust nut will ensure to a reasonable degree of confidence that the legs are perpendicular to the shaft (and therefore the USB bar parallel to the shaft). So when you true the stone you're not actually grinding a cone, and even if you are, your support will be parallel to the stone because you always have the same reference surface. How much of an impact that has though...

FWIW, if you already own an MB-100, (or don't need all the features) Rich (Colvin Tools) is having a sale on his FVB.

Just for info for anyone interested...
I have found the MB-102 available soon online here in Europe for 89 euros. Very good price for a FVB and extra functionality for those who may need it.

Well, I bit the bullet and bought an MB-102.  I wasn't much interested at first because I already have an MB-100 and a shop-made FVB.  However, I use the FVB on my bench grinder and belt grinder, so I really need three.  I don't use the belt grinder much, but do use the bench grinder a fair bit, which has an 8" dia., 80 grit CBN on it (not shown in pic below).  Thus, two FVBs should work fairly well. 

I'm amused by the musings about alignment accuracy. My thought is that it will be self aligning with the first locking knob being secured.  This will force that shaft into the bottom of the USB sleeve and cause it to be fairly well aligned with the centerline of the USB sleeve, which hopefully and expectantly, should be machined parallel and/or perpendicular with the machine grinding wheel shaft.  No guarantee of that, but by assumption, we all rely on this for both sets of USB sleeves.  So, my though is to tighten one knob securely and then the other and proceed with remaining steps. 

It would be easy to check the assumption of squareness by examining the gap between a USB set very close to a diamond wheel, which itself is presumed to have been machined (and coated) square.  Not sure it can be assumed that a just-trued grinding wheel would be, as it is likely trued in whatever plane in which the vertical USB is set.

*NEW TO THE FORUM*

this may be on the froum somehwere, but am wondering if the MB-102 can be used to sharpen Helle knives on the flat side of the stone?

any info would be greatly appreciated.

Thanks

Not sure if you mean the brand "Helle" and if you're asking about sharpening a Scandi grind?  If so, you might find these threads of interest...

(If not, nevermind) 

It is possible to sharpen a knife on the side of the wheel, if that's what you're asking.  (But if you read the above threads, you may not want/need to.)

You may also want to look at this Tormek video (starting at 37:44)...

... it also shows sharpening on the side (around 41:00).
