Possible small production run of Adjustable Offset SVM-45

[RickKrung]

I'm sorry there hasn't been any word on this.  The short of it is that production costs were too high to make it feasible.  Interest was about 40% of the quantity that had the lowest per unit quote price.  Neither Mike or I have the kind of cash to front for it and have hanging out there, even if the return were more attractive.  So, for the foreseeable future, the project is dead.

Hi Rick,

Plese send me some info on this, I might be able to fund this, but I need some more info on price and totalt funds needed.
I love the idea and I think it's sad that it wont be made just because of the lack of funds

Best Regards

Good evening,
any significant NEWS?

[Scotty]

I am interested.
Thanks

[RickKrung]

There have been no further developments.  Until something does happen, this matter is closed. 

Sorry,

Rick

Great idea.
Thanks for the rapid response

I like the concept describe here, however I think that the jig centering bushing from JVH (//forum.tormek.com/index.php?topic=3918.msg26586#msg26586) do nearly the same thing and is simpler to do. I plan to do one for me soon to try it.

The thing with this eccentric is that it is probably not easy to set up. It needs to be done by successive trials.
I do think that a good solution could be to design a new plastic holder which incorporates the eccentric and an angular graduation (see my drawing).  This could be printed with a 3D printer.  This solution could be very accurate and cheap. I don't have any experience in 3D printing but I am sure it could work. If someone wants to work on it, I would be happy to contribute and to describe more in details my idea.

The shape of the eccentric is already available in my spreadsheet. You can find it there : //forum.tormek.com/index.php?topic=4326.0. I could easily add the calculation required to set up accurately the eccentric based on the knife thickness and the knife tapered shape.

I suggest you either: 1) start a new post/thread with these offers, or 2) append these offers to the posts/threads related to the eccentric bushing. 

Otherwise, they may get lost here and/or just not seen by enough who may be interested.  Plus, I think it deserves it's own place in the cronology.  This thread is essentially dead.

It could be "the egg of Columbus" excellent idea.
I hope that the most experienced and qualified friends can make their valuable contribution to definitively solve this problem.

Apologies for dragging up an old thread. I'm just having trouble working out how the prototype on the first page works? I can see the two parts are joined by a dovetail but how does the bolt either adjust or secure them?

[AGRV8TD]

Hey Michael, I understand that this project won't be going ahead.  Is there any chance I could see or get hold of the design just to make my own version on a manual mill?  I understand if this is not possible.  But I'd be keen to make something similar without having to go through all the trial and error process.

I believe that jigs, especially knife jigs, should be as simple as possible. Having an adjustable SVM-45 just seems too complicated to me. Using Wootz' recommendations as a guide, the majority of my kitchen knives fall within the acceptable thickness range of the unaltered SVM-45. A couple of my thicker chef knives are slightly thicker than that range, as is my Mora Garberg. However; these all fall within the range of my SVM-45 with the Wootz recommended .5mm milled area. For the odd knife, which I do not presently own or plan to own, I also have an SVM-45 milled to 1.0 mm and a KJ-45.

It seems to me that my unmodified SVM-45 will cover most of my needs, with an assist from the .5mm milled SVM-45 and KJ -45 when needed. Am I missing something?

PS I also have a set of feeler gages modified by the same machinist if I should feel the need for tighter precision.

Mike's design was brilliant and I'm really sorry it never made it into production.  I do agree, in one respect, that it was too complicated, but only in regard as reflected in the cost of production.

That would be me.  I also think Wootz's design for modifying the SVM jigs and use of shims was brilliant.  I did this to a couple of my own SVMs and did the ones for Ken and modified the set of feeler gauges for him. I have never tried using the modified jigs without the shims, but feel they are simple enough to use that it is a shame to not.  A standard feeler gauge set is modified by shortening to be only slightly widher than the SVM-45 jig.  Standard width feeler gauges work fine on the SVM-140 jig (have not modfied the -140). The table of shims per is shown below.

Back when Wootz's modifications were first introduced, some were interested in having me do the modifications.  I wasn't able to do them at that time, but have considered it feasible more recently...  ...at least until I sold my house last week and am in a crash program of moving my household and workshop.  Once things settle down and get my shop back in operation, I could considered it again.
