I've made several of Rossbotics tool plans but this one takes the prize imo. Very challenging as many dimensions are quite critical. Took me a couple weeks to complete, an hour after work and a few more on the weekend. Made a few mistakes but was able to adapt the plans to make it work and I'll say so far it all works except I've not made a dial yet. Rotates nice on the gear and the collet locks up well. Very pleased I bought these plans.
Ask any questions and I'll try to answer.
