need a chart of Del Jets vs Drill sizes.

I searched, and can't find it, but I swear I saw one and printed it, and lost it.

Was I dreaming? Am I losing it?

This is the only one I know of, but it's not complete by a long shot.

Re: need a chart of Del Jets vs Drill sizes.

from probing with my micro drills delly sha jets seemed to be numbered in hundredths of a mm, ie, 100=1.mm hole, 50=.5mm hole.

Re: need a chart of Del Jets vs Drill sizes.

damn. not complete by a long shot is right...

Mac, If what you say is correct then the chart is bucked up.

I am going to go with the direct to mm conversion as a working point, when I will just drill til i go to far and then just drill a fresh jet one step back.

i had a lot of fun with a tip cleaner for a mig welder. little needle files. filed one out till it was too big then filed one out a little less.

Re: need a chart of Del Jets vs Drill sizes.

There are about three jet sizes between two number drills like between a 67 and 68 drill size.

69 drill equals 72 jet

68 78

67 82

66 88

65 92

64 96

63 99

61 102

Re: need a chart of Del Jets vs Drill sizes.

yeah, my micro drills are numbered like that, and in thousandths of an inch, and converting that to mm it seemed to line up pretty close, like the .026(.66mm) will just barely fit through a 66, but I only have certain drills and jets that seem to match.

Re: need a chart of Del Jets vs Drill sizes.

I found drill sizes by the 100th of the mm. jewelers drill

I drilled out to a 102 then..

still feels like i a bogging but was gaining some power the bigger i went.

I am going to check again for leaks. I just built this case, dont know why it would be leaking. I checked it thoroughly.

the setup

polini 4 petal reed case

parma crank

parma 70cc h20 kit
