fiesable hypothetical thinking is where new ideas come from

props to anyone with that capacity

 

i vote weld and grind

 

The next step is determining practicality, critical before making a post. Also a valued capacity.

 

Time vs money - the answer is as obvious as it is individual.

 

---- done right thats around 400 per cam

 

I've spoken to machinists who've seen two welded crankshafts that they liked in their lives. That's not a cam, but it gives you an idea of what to expect going that route if you don't find the best welder possible and make a point of not asking how much it costs before you decide who's doing the work.

 

I'd love to see someone attempt to drill and tap an m4 bolt into an oem camshaft.

 

I see what your trying to accomplish here... but your asking for a lot of headache. Tell me... how do you plan to drill the hole perfectly center, perfectly straight, on a rounded surface? Because each lobe would have to be precise. Not only that, but you have no way to accurately check each lobe. Yes you can use a caliper to check the highest points, but only the highest points. Your valves may open the same amount at the peaks, but one may stay open longer than the rest depending on duration. JB Weld is a bad idea, it wont hold, especially once it heats up. Threads would probably hold for a while, but not for a long time. The stress would cause them to get stretched. Even with Loc Tite the bolts would eventually work there way loose.

Another thing... cams are hardened steel. Good luck drilling and making clean threads. I work in a steel manufacturing plant. Hardened steel is not something that can be easily cut or drilled into.

 

just do it to a set of ching chong meow cams that usually snap
