My home made FVB is so shallow the Universal Support hits the Tormek housing about half way down.

Home made?  I am interested in what you did.  Your photo shows what looks to me like a cast part as your FVB mount.  It also appears to be a smaller piece that mounts one each end of the USB clamp. 


Could you post some other views of your FVB mount - the part that attached to the USB clamp and had the 12mm rods extending out, please?

Quality is like buying oats.  If you want nice clean, fresh oats, you must pay a fair price. However, if you can be satisfied with oats that have already been through the horse, that comes at a lower price.

Rick beat me to the punch :  I wondered the same thing.

I couldn't find square tubing or aluminium block in the right size, so I decided to try clamping the legs directly to the XB-100.

I found these "12mm linear rail shaft support" on AliExpress:

Drilled and tapped four M5 holes in the XB-100 and screwed the clamps in place.

Used a "12x300 linear shaft" in one of the clamps and a threaded bar from a local store in the other:

Time will tell if it's solid enough  :)

PaGorg, that is really a clever and cost effective solution. Thanks for sharing.

My guess is it will be strong enough but if you find it is not you have the option of mounting the SHF12 Flange Mounts to a 107mmx50mm backing plate and then mount the XB-100 to that plate using the existing 4 holes (or perhaps that's going over the top :)).

PaGorg, simple, clever and inexpensive solution. Thanks for sharing. I am almost sure it will work fine.  :)

For grinding angle setup you can use one of several free spreadsheets available on this forum. My excel spreadsheet entitled "KENJIG_wheel_support_distance_1" enables to calculate the wheel-support distance for given wheel radius, projection length and bevel angle. https://www.dropbox.com/s/ypbtaxgycgoyls0/KENJIG_wheel_support_distance_1.xlsb?dl=1

It was discussed several times here, e.g.:

Thanks, Jan. I'll have a look your spreadsheet.
Right now I'm trying out the "TormekCalc" spreadsheet by 'jvh', and it seems to work great.

TormekCalc - Excel spreadsheet is quite sophisticated script. I recommend it!

I have checked the numerical accuracy of TormekCalc by calculating the height of the USB above Tormek housing and also the distance between the USB and the wheel surface. I can confirm that TormekCalc results are identical with my results with an accuracy of 0.001 mm.

I Received my FVB Yesterday after waiting in pure anticipation for what seemed like a month but was actually a week. The postal system sent it back and forth and after tracking it through numerous phone calls I drove 60kilometers to go and collect it in a whole different town......

But never the less I got it, and after using some very good advice from Wootz via mails I have at last with the help of Tormek Diamond wheels and the FVB achieved the next level in sharpness compared to what I was used to. Still have a long way to go to get extra felt wheels and various compound but from what I have I have at least achieved hair splitting sharpness!!!


Thank you so much Wootz for all the effort in getting the FVB to me as well as the advice. So much appreciated!
