Camshaft

[mobile_bob]

i know we can get a foundry to cast up some cast steel or cast iron blanks
you just need a pattern, which is generally made of wood

our local foundry will do short runs, if one is not in a hurry and can wait till they run another project
they will then finish up with the small projects

they do mainly cast steel i am told.

you don't even need to carve one out of wood....just sit down with some bees wax and give an original some beef where you want it and some draft where you need it and walla you have a master.....cast 5 or so in aluminum and you are in production....

I'd be willing to buy an accurate camshaft for a twin in the $300 range. I'll bet there are hundreds of people around the world wide willing to do the same with most of those willing to buy in the US. Other places probably dont care about having a precision camshaft, for a couple hundred dollars they just buy another engine. Anyway, I'm interested but only if the price can be held down to say $300, any more significantly reduces the potential sales market.

Your looking for a member here called XYZER he has a post on the forum here most likely in the "things for sale" section Wherehe was asking who wanted one.  here's a link to those posts It's actually in the parts wanted section of the forum.         http://www.microcogen.info/index.php?topic=936.0    My understanding is the cams are under going  testing if the cam guy is not under water from the recent floods. I too am interested in them.

Great thanks much
didnt think he was going to make another run from what things I HAD read. I left him a message Hope he makes more...

[lowspeedlife]

he also makes hollow oil dippers for use with con rod bearings that do not have the groves in the top shell, the grooves in the top shell reduce the abillity of the top shell to resist the load placed upon them in running & prevents debris from getting into them from the oil running down the con rods & into the oil holes normally used to supply oil to the bearings. I'm hoping he'll make a run of dippers soon too.

My cam guy isn't under water!  I do have a slight delay,the Indian manufacturer didn't send me any cam gear weights in the spares order so they are now on the way.  Meanwhile I have a few spare weights around from previously destroyed cams that we should be able to make up 3 or 4 shafts.  I have several spare twins of various ages down in Tennessee so they will be the test engines, my guy is doing heroic work in measuring and recording data - he's much better at that stuff than I am.

so where do you get these NON-oilgroove bearing shells?
Yes I hopo he will make some more Dippers as well Id like a set for my twin.

[JohnF]

`I have a few non-oilgroove dippers left in stock, they were a special order.  If there is enough interest I can look into getting some more.  The upper shell is completely plain, the lower shell has the same grooves as a standard dipper.  If anyone is interested, PM me.

[rec409]

Non oil groove Bearing shells you mean?? upper and lower if thats correct then how much and Yeah I think Id want a set for a twin so 2 sets. upper and lowers.

[Crofter]

Like this but better focused!

[rec409]

ok what ya want for'em...

these are supposed to be better, from what ive heard they dont harbor fine metals in the grooves and and better metals, correct?

I suppose I should be getting  hollow dippers for these as well, Hope I can find those...

[JohnF]

The upper shell is plain - no grooves or holes.  The lower shell is the same as a standard one (but likely better made!)  These shells CANNOT be used without a hollow dipper - that is how the oil gets into the bearing.  I don't want to pee off the admin of the board, so please send me a PM to John@woodnstuff.ca
