He did a different demo of the sine block feature where he tapered a bar using a 2 1/2" Bader serrated wheel and a 300 micron Gator belt..
Then is it is possible. There is no description on TW site and the last time I talked to Travis about the attachment, he didn't mentioned the tapering option, but I did know that he was working on some improvements to the jig. I just wonder how it works if you do a taper on both sides or a blade, as the second side's taper should be double the degree.
In any event, I would look for a real surface grinder before purchasing a 1K attachment.

Marko, the current version has a "registration" pin at 6 inches from the pivot point and one at at 3 inches, so you space it for the initial taper at 6 using a feeler gauge (?) and when you flip it over to do the other side, you can use the same spacer at the 3 inch mark. It also has a dial indicator. It would appear that Travis has really gone the extra mile to make this thing easy to use for the mechanically impaired like me.My concern with a real surface grinder is how much it would cost to get one in good working order and then modify it to work with belts, especially if I am already looking to buy a second grinder and convert my KMG into a dedicated horizontal platen setup most of the time and possibly buy a KMG "flatbed" grinder too.
Hard to say. There are some limitations to the jig that make it not very attractable at the current price. I would not think twice about getting another TW-90 though.

Of course there are going to be some compromises, but having done some preliminary research on the cost of doing the same thing even with an old "real" 6 x 12 surface grinder or one of the Chinese made benchtop grinders from Grizzly or HF and a sine plate /mag chuck plus belt conversion, the $1000 doesn't seem so quite so bad as long as it does what I need it to do, which would primarily rudimentary tapering and flattening and getting damascus billets in a flat enough form that stock removal guys could use them.
I am thinking 618 - 624 Brown & Sharpe Micromaster from 1970s if I end up going that direction - I have no money to waste on imports (ones that are made for the likes of Clausing might be an exception). Until then, I can get a very good distal taper without any jig.

Custom and ready-made (coming in the future when I figure how to manage my custom orders better) will be virtually the same knife with the only difference being that the latter I will make without an input from a buyer. So far geometry and profile selection has been left to me on most custom orders, so the two will be very similar in all respect, except ready-made will have handle material and combination selected by me.
I will have curly koa, curly maple, Arizona Desert Ironwood, Ebony as my wood staples. I might add a few other types of wood as time goes by. I will continue using horn, but will look for other materials, as well as other constructions of a handle as well.
Oval, and Western handles will be available shortly. A hybrid oval/Western wa is in works.

That's awesome.

"Don't you know who he is?"
Ready-made knives will give me a little more flexibility on size, production time, etc. Communication and customization takes time - say you make 3 knives of same size, profile and geometry with handle material you have on hand, you get them done faster than 3 custom knives with different profiles, geometries and handles.
