My Friend KWIL has made one of those, couple of photos in his album on ME Forum, there is quite probably a thread on teh forum too
Why use gears when VFD/3phase motors exist?
Bjorn_P:Looking good!Further to my mention of the spindle lock, I recall being told that later spindles were drilled deeper than original so as to accommodate longer tools.When installing or removing tooling it is recommended to put the gear in neutral, presumably to avoid overloading the gears, a point that I have sometimes forgotten!
I hope that top gear is the one you made a mistake on Bjorn. The teeth tips are quiet small compared to the inside diameter. It may just be a photo illusion. You have been doing some very nice work and I have been following quietly.Don
I've noticed that my Chinese module cutters are numbered the other way round from the standard Brown & Sharpe system where #1 cuts 135 and above. On my Chinese MOD cutters that's a #8....

If you are refering to the smaller gear, i is cut with the correct infeed and correct #cutter, on a correct diameter blank. I had to double check that a couple of times as I allso believe the teeth are a bit thin. It is a 32t gear and it could be just the matter rhat this is very near the end of the range for that cutter (next cutter starts at 35t). It could allso be due to the well known chinese quality control.
Bjorn, can I ask where you acquired the plans for the Quick Step? Seems that Hemingway doesn't have the plans on their web site. I am interest in this tool.Don

Bjorn_P:"I forgot that I had a complet set of adjustable reamers, must find some use for them sometimes."I have heard of them being used as expanding mandrels to hold work between centres but I have never tried this. I used one to get me out of trouble the other day but always feel more comfortable with a normal helical reamer.Good luck with the gearcutting!

BjornThis thing you just mentioned to make the stock diameter smaller before threading. I did not know this. Is this also true if you threading with a die?Vince
