Thanks again Jeff

You are right - it was that source (review/comparison of the old and new truing tools) and I did think at the time that there could be other motives behind it.

Thanks for all your helpful advice. Taking everything into consideration I think I will indeed benefit from upgrading both grindstone and truing tool.

Hopefully I will let you know how it all works out - once I have them and put them into use.

Many thanks - Neville

Thanks for that Jeff

It sounds like the TT-50 will be a good move. I had read some reveiws previously that stated the ADV-50D was still a better truing tool - so had hesitated to get the TT-50. Will the SB-250 stone take much longer to true than the SG-250?

When you say that the wear on the new SB-250 is half depending on tool shape - I am constantly sharpenening (touching up not reshaping) small bowl gouges and detail gouges (HSS) - will the SB-250 form ruts and grooves half as quickly as the SG-250? Or is it really only an improvement for wider profile HSS tools such as skews, chisels, planer blades and such like?

Thanks again Neville

Hello Jeff

Have you heard from Tormek Sweden yet? You were waiting an answer - regarding my previous post questions to do with the new Blackstone Silicon grindstones in the General Tormek Questions section (April 04, 2009) and the Woodturning section (April 02, 2009). I am keen to hear any advice or feedback as to whether to go the SB-250 way or not. Thanks.

Neville

Thanks Jeff,

I look forward to that - I will be glad for any help/info you can come up with.

I am new to this forum and have posted a question in the woodturners section about the new Blackstone Silicon wheel, and now wonder whether this section is the better one to post my questions in - so I will try again here. Also I see some have already asked similar questions about the new grindstone in this column - so I have some answers to some of my questions.

Being a fulltime woodturner I am keen to cut the downtime trueing the original SG-250 stone as it quickly gets grooves in the surface after just a few touch up sharpenings of my HSS gouges. I have the old ADV-50D trueing tool - Would the newer TT-50 do the dressing quicker? I do find the ADV-50D rather fiddly to use whereas the TT-50 looks to be a one piece jig - so maybe set up time is quicker? How much less dressing/trueing will I need to do if I buy the new SB-250 grindstone? (Check my post in the woodturning section for more details re this question) It sounds like the new grindstone would be better for my situation - but I wonder how much so?

I see from other posts that the grading of the SB-250 takes longer would that also be so when dressing it? Would be glad for any advice shared.

Hi there - First of all I am new to This Tormek forum but I think it is a great service and I am already finding it very helpful - reading the posts and replies. Thankyou for this.

I am a woodturner and Tormek 2000 owner - it is a very good system. I mostly turn bowls from NZ swamp kauri (wood that has been buried for thousands of years) which can be very abrasive on the gouges so I need to sharpen very often. I find I have a lot of down time in dressing (trueing) the stone, as it very soon has ruts form in the surface when rolling the gouge in the SVD185 jig - mostly where the nose of the gouge contacts the stone. I was considering an after market Diamond wheel but have since found out that they haven't been successful. So I was more than interested to hear of the arrival of the new Tormek Blackstone Silicon stone.

I have looked for reviews or feedback regarding the SB-250 but I guess it is early days yet for that. Have you done any comparison trials with the new SB-250 stone against the original SG-250? Or maybe you have had feedback from owners of the SB-250? How much harder is this new abrasive composition compared to the original? How often would you need to dress (not meaning grading) the stone in comparison - ie - half as many times or a quarter as many times or less? 99% of the tools I sharpen are HSS. Maybe even knowing what the composition of the wheel would help. I would be more than happy if I could cut down the time consuming dressing/trueing of the stone. It would make a very good system become even better! I just want to make certain there will be a significant improvement before I take the plunge and buy the SB-250. I will value any advice regarding this.
Thankyou - Neville
