Toybreaker Posted April 28, 2008 Report Share Posted April 28, 2008 I have played with porting my cylinders myself. Did not use "timing" i just used the deck to measure from, and either ground closer to or further away from in equal distances on both cylinders plus or minus about .010" I keep reading about port timing and that sounds like a beter way of porting. Soooo i have a degree set for cam timing but the wheel is too freaking big to use easily on a banshee engine. what size does the pro's use and where do you get them? also what do you use for a piston stop? Thanks for the info. Quote Link to comment Share on other sites More sharing options...
mopar1rules Posted April 29, 2008 Report Share Posted April 29, 2008 i plan on doing my own porting too. i want to know as well where to get this degree wheel. Quote Link to comment Share on other sites More sharing options...

Thanks for the info. This pro, for one, hardly ever uses a timing wheel. They are great for 4 pokes when checking advance, retard, and total open. For two strokes, math is best but you can definitely get there with a wheel. Mine is by Motion Pro. For a piston stop, we do not use one at all. We would use a special adapted vertical dial indicator dropped in the plug hole. Highest measurement read on the indicator will true TDC. Kudos for doing it the right way! You will be happy in the end and even if your motor does not make 100hp, you will know where you are and how to make it better.

Thanks for the info. I have one I made and a 12" wheel from Moroso. I use the Moroso wheel the most........., but I usually do my porting on a CNC mill, so all I am using the wheel for is to check everything during assembly. :geek: Quote Link to comment Share on other sites More sharing options...
mopar1rules Posted April 30, 2008 Report Share Posted April 30, 2008 http://www.tavia.com/free_degree_wheel.html try this. thanks man! i went there, downloaded it, and now i going to try it out. pretty cool. thanks again! Quote Link to comment Share on other sites More sharing options...

It was a light switch. I would love to be able to just mount them on a fixture in a 4 axis HBM or a 5 axis machining center but i don't work in a CNC shop anymore. how long does it take to run a set of cylinders in a mill?

mopar1rules Posted May 2, 2008 Report Share Posted May 2, 2008 i run 3-axis vertical machining centers at work. have you done this with a 3-axis vmc before? Quote Link to comment Share on other sites More sharing options...

Run time varies based on the complexitiy of what you are doing........ If you have a 4 axis VMC, you can do a pair of OEM cylinders in an hour. If you ar willing to hand finish parts you can cut your run time down, but I usually do very fine step-over surfacing operations so that I don't have to touch the cylinders when they come out of the machine. My cub cylinder block took about 6 hours to run and Twister block was about the same. :geek: Quote Link to comment Share on other sites More sharing options...
