Post up your ported cylinder Artwork

[Mastermind]

Whats best method for removing the bulk of material on top transfers? I've experimented with a few cutters on my right angle handpiece but it vibrates alot and can't seem to get a smooth or reasonable cut. Is there something that works best or is it normal to get this?

I use these. https://ebay.us/m/5W2RYt

Takes practice. Start on the left side. Wide open. Straight up to the stopping point.

I know that OEM plating is generally harder than AM plating, but I would practice on an AM cylinder before ruining an OEM cylinder.

That was a big part of the reason I played with AM saws ... also to learn a little about porting.

When I do some porting (I'm a real amateur) I look at it like sketching, not drawing. Just do a little at a time and "drift" into where you want to go. A lot of cleaning, and a lot of checking to see what you are doing.

I also stole Randy's method of cutting business cards and using them to draw my horizontal lines from the squish band.

Are you folks running any sort of lube or solvent on the diamond grit tools?
I seem to recall some discussion of it while running the burrs, but don't remember if anything was said about the diamond coated tools.
Granted your bit speed, sharpness of grit, particle spacing & size and the material type(s) all have a part in things gumming or shedding etc..

Thanks, will try that next time.

I don't use anything on the diamond burrs.

Did some more work on the uppers and they are way better than they were before and I've figured out a lot from the advice given especially from the chief cook and bottle washer... I'm not sure if I can get this particular cylinder looking much better but it's been a great experience and if I end up doing any more saws I feel like I have the confidence that it will be better than this one. Confidence can be a double edged sword but I will approach any future project carefully. Thanks all for the feedback and I'll post how it turns out once I get some run time on it (unless it turns out to be an embarrassing turd)... LOL





I got the aiming kinda where I want it... hoping that it works well... I would have preferred a smoother transition from the flatter roof intake side of the upper to the sloped roof exhaust side that opens 2* before the intake side trying to aim for the spark plug, kinda... My skills aren't there yet (if ever). Not exactly artwork, more like my version of a stick-man portrait.
