The grinding between the primary and secondary relief was somewhat wavy. Video inspection showed peaks and valleys of .0002-.0008. The odd part was it was...

    Truing a shaft/cutting tool after heat treating

    I am making a couple of HSS cutting tools (M2) and have just had them heat treated. The diameter of the tool blank is 1-3/8". It is 4" long. A 3/4" x 2-1/2" shank will be the end result.

    Parts / Accessories needed for Brown & Sharpe 13 Universal Grinder

    I picked up a Brown & Sharpe 13 about a month ago and have now put it in place and started running it, mainly some testing and very minor operations for jobs in the shop. It did not come with a tail stock. I didn't think I needed one for the operations I was going to be doing, but now am sure...

    Purchased a Brown & Sharpe 13 - Am in need of parts for it

    I just got back to the shop with a Brown & Sharpe 13. The machine itself is in good cosmetic condition, but the only accessory it came with is the power workhead and a 4 jaw chuck. The power table traverse works well, but the hand movement of the table seems as if it is going to need work. I...

    Tree Milling Machine - Question Regarding Particular Use

    4 months ago I acquired a Tree 2UVR milling machine. I am not a machinist, rather own a sharpening/grinding shop and need it for only one application, boring out the arbor hole on saw blades to our customers specs.

    Cincinnati Monoset Help With Spiral Lead

    I have been learning to use our Cincinnati Monoset recently. I have many questions, that I cannot find answers on with any of the earlier PM Monoset topics.
