New Fire piston!

[rich59]

Well, I was getting better results with my piston today having switched to using vaseline for my lube; but my gasket string has just come loose! I'll have to re-do it tomorrow...

Could I suggest you post a series of pictures of the process of replacing the gasket? A close up or two of the piston without the gasket on it would be great as part of that. I am sure others would benefit from your experience. For myself I occasionally try and make a DIY fire piston and I am finding it hard to get the whipping to lay flat where the cord crosses over the underlying cord.

Jeff supplies some excellent photographs of the string replacement with his pistons. I too wondered how to make the string flat but it does not cross over itself but passes though 2 holes drilled through the shaft.

I can't find my destructions that came with my JW piston . And i made a pigs ear of it when i tried. Is it literally as you describe ? i.e. through the hole, around and around, then through the top hole...?

Its almost that easy. Please provide me with an email address and I'll send you replacement instructions.

I have yet to replace any of the string gaskets. I am hoping it is as straightforward as the photos show. I inspected my Wagner piston carefully before any real use trying to see how it was wrapped in anticipation of the event. I noted it had 7 complete wraps. I was a bit to excited when the Aune piston arrived and did not note the wrap details. It is in Darrel's hands now for tuning and when it returns I will note a few details.

edited to get Darrel name right....

Gasket replacement should not be a common requirement. I use mine rather often and change the gaskets in perhaps a year and a half or two years. Rewrapping a gasket takes me about 5 minutes, but as with anything that a person does a couple of thousand times - practice makes perfect.
