Newbie in search of Plans for a Cam Grinder...

[CNC-Joe]

Group,

I am a newbie, with some basic machining skills and some cnc equipment .. wanting to get into this hobby after seeing the inspiring work here.

Can anyone help me find info on designing cams?

Can anyone help me find a plan set for a cam grinder?
Prefer a free one.

If you'd like -you can send files to my home email address:

of course - replace [AT] with the @ symbol

Thanks for any help!

I found this video it might give you some ideas on making a cam grinder.

Wow! Thanks Paul! That's a really awesome camshaft grinding system.
Do you know where I can find plans for making something like that?

Thanks for your help!

Model Engine Builder Magazine , issues 21-25 contain a very good series on designing and grinding camshafts. See http://www.modelenginebuilder.com/default.htm

any basic IC engine plan that needs a cam should have the cam designs.

you say you have cnc so why not rough out the cam with cnc and touch up smooth out by hand.

You should not need a cam grinder unless you are doing something complicated like a v-8. I suggest you start with a single cylinder engine then a double or two before getting into complex ics.

Hmm- that gives me an idea - I could possibly cut out the cam lobes on my mill then silver solder them to a shaft... just rotating them to the correct position before silver soldering... might just be worth a shot - as I do see valves that are put together with silver soldering... dunno! Maybe might work

One of the things I often see in the homebuilt cam grinders is the lack of HP and ridigity. If you look on ebay and other sites for a Gorton single point grinder, this has many features needed in a cam grinder, and they sell cheap, around $150-300. Cast iron, compact, real grinding spindle, 1/2 balanced motor, 7000 spindle rpm, and a rail mounted workhead, that once removed, provides space to mount the cam turning setup.

I have one of these grinders which I use for grinding carbide bits. It just looks so right to be made into a camgrinder.

Wowsers! Thank You MachineTom, canadianhorsepower/Luc !!!
That article by Joachim Steinke is awesome!!

Merci beaucoup - Luc!

( Vielen Dank, Herr Steinke - zie CamGrindung machienen ist wirklich sehr gut! ) Ok so much for my German language skills ( es ist nicht meine erste sprache )

That's exactly the sort of thing that I'm wanting to build.
I can see that this place has an abundance of knowledge and skill.


Thanks again, Guys!

Yah - Steve does great work. I actually know Steve. He lives nearby. Real busy guy, though.

Joe,
If you have a rotary table you can use an end mill and CamCalc, Google it. If you can program the steps it would be quick, otherwise it's tedious. If you set degree per pass setting at 2 degrees it gives you a nice finish. I used it on my Upshur verticle single. Don't need a grinder for that. Unless of course you want to make a grinder.

Hi Art,

- All I can find when googling for that CamCalc - is an Android app for camera's?
- Do you have a link to the website?

Sure appreciate the help, everyone.

I'm thinking I'll start with a wobbler air motor, then maybe go to a V-2 or V-4 wobbler. Then a 1 cylinder IC. I'd really rather do the IC stuff.

An interesting difference between the grinders referenced above. The one by Ken uses a straight edge follower against the master cam, while the one by Joachim uses a curved section. This will be more accurate than the straight edge since the wheel generating the cam is round. The flat follower will cause a different profile.

Hi Joe,
Here's a link to CamCalc. Its on another forum though, so I hope it's ok to post here. An engine idea is the Hamilton Upshur vertical single in issues 63-66 of Strictly I. C. magazine. there are a lot of plans for single IC engines someone else may have more like Jerry Howell plans.

Never too busy for you Joe!

 

[CNC-Joe]

Art - Thanks for the links. I can see getting a bunch of back issues of Strictly IC... looks like there's a wealth of knowledge out there.

Steve - Hey - I know you're busy. Was great seeing you today for the engine block casting. Definitely will have ot do it again sometime soon.

Art - those links are Awesome!
