I do mine on a Bridgeport as you see in the above photo, so I go up or down

Re: Seeking Knowlege on the Machining of a Bevel Gear.

Yes Charlie I go to full depth . One correction to your comments You have it by the way ! :) On the second and third pass, you raise OR lower the cutter as well as rotate ( so it matches the small end exit point) This means it cuts a taper . Lots on the large end and nothing at the small end. Here a...

Re: Seeking Knowlege on the Machining of a Bevel Gear.

So from that I think you concur that I can use a standard cutter? Absolutely ! But, the Pitch you use ( ie 16 or 20 or ?) depends on the small end of the bevel- not the large end ! Use the small end to determine the Pitch and the number of teeth All your offsetting is to generate the larger diamete...

Re: Seeking Knowlege on the Machining of a Bevel Gear.

Charlie, I think you are getting too deep into that book What they are referring to with the 1/3 rd comment is the face of the gear In the sketch below, I show the 100 % "Length" they refer to and when they say "one third" or 33 % When you go more than 33 % , the gullet ( or depth or root -other nam...

Re: Seeking Knowlege on the Machining of a Bevel Gear.

Charlie, I have cut many bevel gears in my shop using my Bridgeport and my 1890 Brown and Sharp Dividing Head Cutting bevel gears requires more setup and calculations, but it is not that bad. The gears you cut will not true bevel gears because they do not have a conical form, but will have a straigh...

Re: Diaphragm fabric

Harold, I know you want to keep the sensor cherry, but
you could substitute a air compressor cut off switch or other none water pressure sensor
by adding an air leg ("T") and putting the sensor at the top in the air space where it never contacts water .

" Steam would easily leak between these ports right under the plate."

I think you want to use some Permatex there to solve that problem

Re: Power two machines with one motor

Steve, When I visited England to attend the ME show a number of years ago, I happened to be invited to a British Gentleman's shop which was a garden shed and only maybe 5 feet x 8 feet or so and he had one motor and it drove his ( small) Lathe, Mill, and drill press- one at a time. The motor powered...

Re: Bandsaw downfeed control

Too complicated for me
My 1983 Taiwan cutoff had a crap control
I now have a selection of brass and steel rings ( 6" OD x 5 "ID x 1" ie.) for weight that I just hang on the Blade adjusting handle
depending on the load at hand. Works slick and no maintenance
