Gday, this design of the floating reamer holder is from Nigel at Go Create Hobby Machine Shop, the plans are very well made and very easy to follow, I'm really enjoying this build so far, setting the compound to the correct angle by using dial indicators is something I haven't done before and this turned out to be a perfect fit, this would have to be the best morse taper I have ever machined, I hope you enjoy this build and if you haven't seen Go Create Hobby Machine Shop then please take the time and have a look, the work Nigel does is first class, take care. cheers Matty
