The build off this time will be Dolmar/Makita 6400 - 7910 Solo 665 - 681 saws. Rules will be very simple. I will take care of the fuel dump, and refueling, will supply the off the roll chain, and will have an eye on the timing, and the classes. The build off station will be setup away from the cant racing so we will be able to concentrate on what we are doing. Expect some serious competition gentlemen.

We will be making two cuts in a 24 x 24 pine cant. A 28" bar will be used. We will make one cut off of each end. Then two cuts in a 12 x 12 pine cant, with 16" bars. Again, one cut off of each end. You can use any 3/8" rim you want. In Class One, we will spin a loop for your setup. The four cuts will then be averaged, and that will be your "score".

Class One:

Any Dolmar or Makita 6400 - 7910 bottom end of stock stroke length can be used. Top end can be anything that is intended for that chassis. Wanna run a 6400 jug? Cool. Wanna run a BB top end? That's fine too. Chain in this class will be off the roll Stihl RS 3/8 .050 - Fuel will be supplied, non ethanol at 40:1, all saws will be dumped out, and refilled with my fuel, then ran enough to be sure the event fuel is in the carb. You may need to re-tune......I get it. Be prepared though.

Class Two:

Much the same as Class One.....Any Dolmar or Makita 6400 - 7910 bottom end of stock stroke length can be used. Top end can be anything that is intended for that chassis. Standard bore, BB, OEM, or AM. Chain in this class will be the difference. You supply the chain for your saw. As in Class One, fuel will be supplied, non ethanol at 40:1, all saws will be dumped out, and refilled with my fuel.

Class Three:

In this class the Solo bottom ends of stock stroke length are also allowed. So, any Solo 665 - 681, or Dolmar/ Makita 6400 - 7910 or any combination of those saws is allowable. You will run your own chain......but will run my fuel. That means Alky, or Nitro saws are not allowed.

Now......read these rules again. Then, ask any questions you like......and let me know if I made any mistakes.

Edit: Just muffler saws. No pipes.

Edited again to clarify stroke length.


Seems there will be more than a couple saws with 38mm stroke.
Any chance we could add a class to run them with off the roll chain as well?
For science and stuffs.

When we get closer to the gtg date we'll get a list of entrants. Then we'll be more able to make a decision about that. I want everyone to have a good time, enjoy the gtg, and feel that we did everything we could to make to fair and fun. When we make that list, we will need a drive count for the chains so Jonathan and I can have everyone's chain ready. I'd like to get started on the build off as early as possible Saturday, so the afternoon can be dedicated to cant racing. The more classes we have the longer it will take of course....

I get it, 100%
My thoughts are that we spend so much time and energy building saws for a build off that it’s a bit of a disappointment not knowing what saw had more nuts because the chain is a major factor in cut speed.
I’m not chickening out from class 3 at all, I’m working on chains and look very much forward to the competition.
Class 1 and class 2 are theoretically the same 37mm stroke saws with a chain variable, how hard is it to do the same with the 38mm stroke saws?

I hear you....and I'm sure we can do those saws with off the roll chain too.

Any objections to using the same chain in both stock stroke and stroker saws?
