That's some patience you have there Steve, oops....do you really need to make another, it looks so good... :(

I suppose you do looking how well you have made the rest of it :clap:

Very nicely done Steve.

You seemed to have answered all the questions I asked you in my email, and also experienced the dividing head that I explained to you.

The advantage of involute cutters is that on materials like you are using, you can go to full depth in one pass rather than the multi pass you are doing with the flycutter. But as we say, what is the rush.

You can buy involute cutters a lot cheaper over here.

After crashing the first gear, the second also bit the dust in the same manner. Repeated cuts on the RT were pretty mind numbing. Since the second gear died while under the final dimensional cut, I took the advice of a user on HMEM and tried the cut in a single pass. The drill rod cutter was up for it and the mill didn't complain any more than when it was taking smaller cuts. 28 passes later I had a much cleaner looking gear than when I was making multiple passes and it meshed well enough to begin the lapping in process. The gears are now running together without any extreme drag and what there is should disappear once I can put the gears under power for a final run in.

Interesting project and I'll do it again when required, but I'd rather eat molten glass than do it for a living....(grin). There are kinder methods for driving men to madness.

I like the gear cutter/cutting Steve.... Again something that will undoubtedly be useful to many of us :thumbup:

As you say Steve, using the dividing head can become very mind numbing, but on this occasion you must realise it was needed.

You will now be able to say that you have made ALL the engine bits, with the added bonus, you have saved yourself a few pennies. :clap:
