Home made gear cutting hobs part 5

[gwheyduke]

Good information ! Thanks for posting. I'm building model engines. Might try making my own gears instead of buying them!

"I don't know the Metric World." LOL! Great video! Thanks for making them!

[ShredBike]

As a mechanical engineering student going into Manufacturing, this video was great to gain some insight to something that I have no experience in :) Thanks!

Hi hobby nut...do you whr to find a good gear hober manufacturer....which is reasonable in price.?Hober as big as dia 50mm X 70length . Material carbide.!

[qwerty9321]

The slitting saw didn´t work making the cuts for me, it ended completely damaged on my first hob. I think that the W1 rod is too hard for the saw I found hereby. A 7mm HSS mill on the other hand worked perfectly and fast.

[Hobbynut]

Great I am glad you found a way to make it work for you.

[naturalyshocked]

they don't use a fornuis to heat treath material, but a high frencuency on a copper coil.

it heats the material in about a second or 2, 3 to red hot.

it's called induction heating.

even some people make them DIY.

[Hobbynut]

@naturalyshocked I think this would be more effort and cost than I would like to get into at this time but it is a good idea. Thanks

[naturalyshocked]

for this you would most defenitly opt for induction.

you can make a tigth coli from copper tube, which runs cold water to cool.

but you can control exactly the parts you wanna heat.

you want hard teeth, but you wanna prevent that teeth brake off, due a brittle shaft.

maybe you should keep an eye on such device, some are equal sized a welding device.

maybe you can find one in somekind of auction.

[naturalyshocked]

if you own such device, you can make high quality gears for people and earn the investment back.

: )

you make a coil around the circonference of the sprocket, turn it on and you see red hot teeth in a flash.

and YES with a good, not DIY device you can also melt all ferocious metals very fast.

no smoke, less smell, faster work flow.

i have no idea what he is making. but i cant stop watching

[Hollrobb]

@golddang Same here, i'am sure i'am learning something but what i dont know. Thanks Hobbynut for talking like a regular joe and not like you are talking to a monkey.

[golddang]

i could watch this totally ripped for hours

[diymania]

You work for csi las vegas ?

[mog5858]

thanks you for all the time you have put in love your work you should teach. your very good at it.

[dlmarti]

First let me say, its damn good to have you back.

Next; Was the video prematurely cut off?

I'll admit some of this video wasn't that clear, but maybe its just me. I probably have to go back and revisit the rest of the series (its been a while :) )

[Hobbynut]

I had to cut this into 3 segments due to size limitations on you-tube. I am working on uploading the remainder. for some reason this has become a very slow process in taking about 10 hrs to upload a single video for some reason.

[skinwehr]

You have probably saved me 500 dollars on gears. Your videos are great! People would pay to learn from you!

BTW, a good course on case hardening is a DVD put out by AGI (American Gunsmithing Institute) They cover just about everything you need to know for a home workshop.

[Hobbynut]

That is fantastic. I am realy glad you found the information useful and was able to use it. I would hate to think what I would have spent on all the gears that I have made. I will google the AGI and see what I can find, Thanks for the info.

[Platypus2048]

Thank you very much sir. I'm totally new to machining and I've learned a lot from you.

Thanks again!

btw. Mills run clockwise here in metric-land too ;)

[julinho1]

You really need to improve lightning.

[Hobbynut]

You are probably right, I think I am a better machinist than video producer. I will see what I can do on future vids.

[julinho1]

That´s what really matter, I´ll keep watching anyway. I ´ll be glad if someday I can teach as good as you do.

[naturalyshocked]

the Metric world?

the US army use metric, pretty much al commercial engineers in the US use the metric system, i can't understand why the footfolk use the imperial system

[Hobbynut]

It is what I know?

[seneca67]

ty for making this vid, i am intersted in making gears.

[julinho1]

fist to watch! thanks for sharing!
