Re: Need help with new tools
Wow...you've inherited some excellent quality equipment there.
Tool sizes don't matter too much as you are only interested in the cutting point. If you are grinding your own tools then the smaller the better as you have less metal to grind! Go for 6mm or the smallest size possible for boring bars as they need to be narrow if you need to bore holes (to make rims for wheels etc. The bigger tools are too fat and the backside of the cutting tip head grinds on your work.
I'd also suggest getting a diamond grinding wheel to sharpen the tools you already have. I've just thinned down a parting off tool (just like the one in the black holder in your pics) to about 1mm wide on a diamond wheel. This tool then allows you to make very narrow grooves and shoulders which is ideal for 1/43 items. With the diamond wheel just sit there and very gently grind way without the tool getting hot. It's actually a very quiet operation and quite therapeutic!
Good luck
