Cylinder/Piston Choices for Custom Built Saw

Based is that a picture of you in the goggles

 

copy pasted info I dug up.

i have decided that i am going to try something a little different with porting saws. this will be a little different approach to getting a saw ported than what you guys are used to. i am going to offer a complete cylinder exchange. what i am proposing is that you send me your good useable cylinder with no broken fins and clean serviceable bore as a core. i will send back a clean bead blasted "oem" ported cylinder,new meteor piston and caber rings,new base gasket,new muffler thats has been port matched to cylinder and dual ported or outlets sized accordingly, with all partaining heat shields and gaskets. i will include in the kit a set of seals for the saw and a carb kit. this will be the ultimate kit for the do it yourself type of guy or just anyone that wants a package deal at a great savings. i am going to start this with the offering of a 372 cylinder exchange.
"wicked work saw 372 kit"
1-oem bead blasted and woods ported cylinder
1-meteor piston with new caber rings
1-base gasket
1-ported muffler
1-muffler bracket
1-muffler heat shield and gasket
1-set of seals
1-carb kit
1-new plug

the cylinder will be ported to the same specs that i port all my work saws. the combustion chamber will be cut and squish set. the cylinder will be set up to use a base gasket. i will port the muffler to match the cylinder and match the gasket and heat sheilds as well. i will be including a new set of seals with your kit as well as a carb kit along with a new plug. this kit will fit in a flat rate shipping box from the usps and will ship priority mail. i will try to put together some guide lines tonight on the cylinder exchange (core). but right now i think i can do this kit for $350.

i will be setting the squish on these cylinders at .030 and that will allow for the possibility of the case being a little different. i havent found any real difference in cases from one saw to the next but have found differences in the cylinder and squish band. these will all be set the same so there should not be any problems.

 

..No

If I have time and who ever ends up with the saw would want me to port it I will for shipping and machine work cost.

 

So the ported 51.4mm would be better right?
I was on the fence after reading the earlier build thread and opted for the stock as KRL seems to be a bit against modified cylinders for long term parts availability - if I had 27 saws I probably wouldn't care

 

Makes me feel better...i have long assumed that to be you!!!

 

da huh da huh da huh...Beavis
I just recalled frog baseball yesterday when turning on containment sump pump and frog pieces flying out the discharge

 

I was thinking it was like $100 more if you wanted him to provide a cylinder?

 

guys I no longer do an exchange on cylinders. I quickly ran out of good cores because what some folks think is a good useable cylinder is quite the opposite. if you send in a cylinder you will get your cylinder back. I charge 200 to do a port job on cylinder only. I no longer do any work on aftermarket cylinders. none zero zilch nada,wont touch one with a pole. the reliability , fit and finish on most aftermarket cylinders are so far from what oem is that I will not put my name on them. you can do the best job that you can possibly do on some of the aftermarket stuff and you still cant get it to perform with the same work done to oem. when I did the meteor kits for folks it was made clear that they in my opinion will not perform as well as the same oem cylinder ported but for some folks that didn't have a good cylinder or want to use there cylinder it was the only choice I had for them. they will run much better than stock especially when you don't have a good cylinder to begin with but it would be my last choice. as I am a dealer these days i sell a stock oem xpw cylinder for $225, not much more than an aftermarket cylinder would cost. if it were me I would take the oem cylinder and when funds were available have it professionally ported by your choice of builder.

 

That's my preference if its not a cookie cutter. If you have the squish cut and base a stock piston will fit tmriggt in with no extra work.

 

Not really against porting a saw, only making it clear that a port job will not turn your 55 Rancher into a 460 Magnum no matter who ports it. Will porting get more out of the saw, yes. Will it last longer than your stock saw perhaps so perhaps not. It depends on many things, no one ports your saw without respect to longevity, however there are design choices made by the manufacturer that porting cannot change/improve and may in fact be detrimental to. For the record I voted for the ported TLandrum jug!

There is an old saying in racing 'if you want to finish first; you must first finish'.

 

I have strapped almost all of my saws besides the 550 on an Alaskan mill to make boards. Some 7' cuts is over a tank of fuel. I've not had one of them that acted funny or got too hot. I'm working on getting something to make a cookie cutter out of this fall though just to see.

 

Wow, then when I put it together with what most likely will be the XPW jug, someone can take you up on the porting offer and have a hell of a saw! Given that you may be porting this saw is there anything I can do in the build that will make your job easier? like use a base gasket instead of goo (1194) so you don't have to scrape that stuff off.

 

I like base gaskets but some saws if you machine them the base starts getting thin. On those I use sealer after machine work.

 

Or determine how you will be selling it, pre-sell & the purchaser will have the option of Mdavlee doing the port work prior to assembly.

 

Good idea Oliver1655, however when Mdavlee goes to port the saw he needs it to be together e.g. complete bottom end with the jug and piston installed. You can have basic porting numbers for a XPW jug but a really good port job requires that those base numbers be transfered to the individual saw taking into consideration the manufacturing tolarances. You will note that for a work saw from Terry that he sets the squish at 0.030 which is fine but may not be as tight as Mdavlee might do it on an individual saw. Porting takes a LOT of time, and no one would be able to offer a port job adjusted specifically to an individual saw, at an affordable price. The idea is to find a set of numbers that will produce a desired result across many saws without having to custom taylor it for each saw.

So, lets say I do a saw for myself and custom taylor the porting of it to my specific saw and get 100% of the desired result. On the next saw that comes through the door applying my set of numbers may only achieve 95% of what I got in the custom taylored version. Using a base set of porting numbers still makes a great saw but does not take a week or more to do.

 

Am I dumb for wanting this saw like right now...even though its not done ?
You guys are making me think I wanna try some of these things . KRL.....I hope I can make it up your way this winter sometime.....I wanna learn more ! Ive gone from just maintaining stock saws......to pulling off carb limiter caps.....to modding all the mufflers that come my way !! Now the next step......better ways to rebuild a top end...and learning some math...which is far from my strong suit Thanks for all this info fellas......It keeps me up dreaming at night !!
