I certainly have no objection to you voicing your opinion, and perhaps he would serve as the endorser and spokesperson for Woodcraft at shows and Woodcraft stores for no compensation. I am confident that he would not serve in that capacity, paid or unpaid, if his comments regarding their products were not favorable. Perhaps we should say that it is fortunate that his endorsements for those products are supportive.
Please remember that like you, I have a right to an opinion.
As regards the iron and chipbreaker sets that were raised in this thread, the ones being sold by Lee Valley offer equal quality for much lower cost, at least over here. You also don't have to cannibalize your antique plane in the process, the way Mr. Cosman recommends in his video; filing the mouth, and removing the lateral adjustment lever and depth adjuster yoke pins. No, thank you.
