Double pipe for Echo Twin

[Dub11]

This saw is awsome and I came across a twin like this with a chance to buy one a while back ( not running ) but was scared off buy lack of parts availability. Is it easy to find Echo parts there?

Thing that sucks about the 510 is its a clamshell block but I like it

Yep agree for clamshell! Last month tried one on old Stihl 084, really sucked since I did not have this type of crank case puller in hand. But was able to do it with some 'modified triangler positioning' lol. I used these green marked thread holes for splitting them.

HelloDub thank you for watching and leaving comments, glad you got a good chance for one of her sisters there! No need to be discouraged with the lack of parts IMHO, you can fabricate some parts on your own actually in a way I tried some for her. Anyways these parts are very rare here too, so we old saw freaks more often have to make it, as far making a parts, a part of our enjoyment, lol.
My old girl came to me with dirt and scares on her too, see below;



Her brake band was missing;


and her brake post got a crack on the front wall;


Will show some more pics of minor repairs.

Thanks Wayne, 302 and 400evl are nice saws of the day, last fall I got one, 302, better if she had a brake but I love her.

As far the Chainsaw Collectors Forums shows on its library, there are three basic types besides OEM saws like the one from John Deere;

Echo CS-601TVLA / Twin

This fabrication of pipes begins with designing, firstly visit JavaPipe site to download a file, then after installation fill out the factors in the dialog, and click! You will get a view like this;

Red letters illustrate the pipe, which I added here.
I put the Transfer Port Angle as 120degrees, but now I think I should have better chosen at least 110 for this. Shame was that I did not make a check on this with my flesh.
This means 130 - 120 = 10,
so the time gap between the exhaust-port-openning and transfer-port-openning was estimated as only 5 degrees,
while
the time gap between the exhaust-port-closing and transfer-port-closing was also estimated as only 5 degrees,
and they make 10 degrees in total.

But this 5 degrees of time gaps for each of the in and out ports seems, even for this small cylinders, a little too small.
I will check it when I have a chance to see her inside again in the future though, lol.

Very cool, looks like you have quite a bit of time in that saw.

Thanks Deets066, I have been wanting to accomplish much faster response on triggers, yes I am quite soaked in saws, lol

Thank you for the info and the links I really appreciate it

You are welcome!

JavaPipe site provides you designs of the pipe calculated, in exploded views.
Then copy these views on a sheet of thin steel with a circle compass,


and cut.

 

[chy_farm]

In case you use a sheet metal of 0.5mm thick, it's not very hard to get them rolled with your hands unless the diameter of the curve is less than some 30mm.

 

[chy_farm]

For smaller rolls, you may use a home made roller like this! ;

[chy_farm]

First place the cut sheet on the roller and press it ;


Move it forward a little ;


Give it some good taps to better round ;


See it with a lot of care ;


Done!! ;




For smaller ends of the cones, you can modify the positioning of the roller, will post more.

[chy_farm]

Modify the positioning of the roller for cones,



Place a cut sheet and give some good bending on both of the axial ends.

Then give bending to the rest with your hands.
Make an inner pad if needed, a baseball bat can be a good candidate;

Shape it to get better straight lines;

Almost finished one of the cones, this is one of the diffuser cones, ;
