Another Kiwi build question

[vcutajar]

Sorry if I am becoming a pain, but I just hit another snag with the piston.

This morning I was looking at the piston dimensions and I think I am missing a dimension on the plans. I cannot find the height of the piston. It could be I am still fuzzy this morning (came back from work in the middle of the night). The photo is a snapshot from the large scale plans I have and I think the dimension that is missing is the distance between the bottom of the second groove and the top of the hole of the wrist pin. I estimated it should read 1/16" and if so the height of the piston should be 15/16" (adding fractions is not my forte).

What do you think?

I think I am becoming paranoid because the piston is a casting and I do not want to ruin it. I did not anticipate the piston would give me so much head scratching.

Again thanks for any feedback.

1" :

2/16 + 4/16 + 10/16 = 16/16

Marcello is quite correct Vince.

You have forgotten to add on the 1/16" measurement that is missing, so the total is 1".

BTW, I would have come to the same conclusion as yourself about the 1/16" missing dimension, purely because E.T. liked working to nice round figures if possible.

Marcello and John

You are quite right. I forgot to add the missing 1/16". I said I was a bit fuzzy and still am. I am off for a siesta to recuperate.
