you roll your hair in the brush roller then-poke the pins threw the rhombus
It depends. To score a spare, you add 10+the next roll. A spare is when all the pins are down after the SECOND roll, regardless of the number of pins knocked down on the first roll. (If all pins are knocked down on the first roll, that is a strike)
Remove the old pins with Vise-Grips and drive the new pins in carefully with a brass hammer (to prevent distorting them).
Check the Brownell's catalog.
The objective is to knock over as many pins as you can to get a high score, which ranges from 0 to 300. You get strikes when you hit all ten pins in one throw, but if you don't, it is okay because you can roll a spare if you hit the remaining pins on the second try. Avoid open frames, missing all the pins, and splits, difficult positions to make a spare.
There is an inner joint roll pin holding the CV joint onto the shaft of the gearbox. You will need to use a arallel pin punch of suitable diamiter to knock out the driveshaft roll pins at the transmition end. Note there are Two roll pins one inside the other.
When all pins have been knocked down after the 1st ball in a frame, the scoring term is called a strike.
I think you might be talking about a backwards roll which is basically a roll from crouching where you lean backwards onto your shoulder and your arms are straightened, and you end up standing.
1/6 on the first roll, and 1/6 of rolling a six on the second roll. Overall, the chances of you rolling a 5 on the first and a six on the second is 1/3.
Ten points plus the pins of the next two balls you roll. It could be as little as ten (if you roll two gutter balls) and as high as 30 if you get two strikes.
A 1 foot roll will remain 1 foot even when rolled up. The diameter of the roll will depend on the thickness of the material.
