What's on your bench?

Diy chainsaw mill, pics after completion,
but it is happening!
Trying to get ready for Ct. GTG. This Dan guy is so demanding! :-/

It's a start...

Kev,

You get that cylinder, little buddy?

Yes sir. Arrived today
Started like this



After some muriatic acid and scraping with a small pick, and 2 minutes with 80 grit on a mandrel, it looks like this



Those scratches above the exhaust port might fill in with carbon after a few tanks, might not. Probably equates to about 2 psi loss of compression. I'm aiming for 200 psi. Might have to settle for 198

Went through the batch I bought today, work for tomorrow is steam washing. Of those I think 2x550 can be builders, best of those will head over the pond, for some odd reason 3 out of 5 had blown con rod bearing. The two 346's, the OE has cracked crankhouse, I dont expect anything from that dirty NE.

Shindaiwa 757, this one got new crank bearings.
Previous owner fitted a new piston but overlooked the bad clutch side bearing.
Just waiting on seals to get here and she'll be ready to fire up

One rough around the edges Oh-6-Four, got it because the thing wanted to break your hand every time you tried to start it, a good cleaning and new coil wire and she is a runner. This old girl is going back into commercial duty so she is getting a new Meteor piston.

Well not exactly on my bench but on my tailgate anyways. Sent these off to "The Wolfs Den" for some much needed attention.

Got one of those and most another on the way. I'd like those bearing and seal numbers.

New Muffler for my 272xp, little different than the old one, little heavier and has a baffle plate in the middle. Hopefully this one will stand up to a terrorist attack ans not fold like a cheap suit. So I just figured I had to modify it more is all. Like my old Hot Rod days, if it blows up, fix it faster. Drilled out the baffle in the middle and made the secondary outlet larger this time to take more out from the first chamber. Fired it up and it still seams in tune, so should be close to where it was before the explosion.

It would of course be better to make a larger muffler with a tuned "short-pipe" in it - but that's a lot of work....

Still looking for a 2100, period correct bar Mr Moderator. Friendly reminder

That will come on another project I have here in the (hopefully) near future. This power saw is my only modified one and is very mild as they go. End of the day it's still just a work saw. Does cut pretty darn good and is still my favorite.

To make a really good "short-pipe" you need to know your stuff to the extreme to calculate it right - and be a really good welder into the bargain, to cram it into a reasonably sized outer shell.

Most people aren't able to do any of that, and then comes the need to carburet and port the engine correctly as well - actually it should happen in the opposite order..

Yes, absolutely, the complex equations would be bad enough to get through, welding I have covered as that was my former trade and what I went to school for. Most tuned pipes aren't "tuned" at all to the motor it's attached to, just simply sounds cool to its operator. For example, I asked a relative of mine, that formerly worked for a big snowmobile manufacturer in the R&D department and was big in the racing circuit back in the day, about making tuned pipes for a drag sled, his reply was, "just gut the muffler, you'll go faster". When I pried a little bit deeper as to why, he said there were guys that did nothing but make pipes, test them and start all over again every day, trying to get them perfect, as the variables out weighed the math and most times was done wrong and made less power instead of more. So that was that, back to what I intend to do, I've been slowly assembling bits and pieces to make a "play saw" for myself, basically something to tinker on in a warm shop during the cold winter. When it comes time to make the pipe I fully understand I'll probably have it wrong, and that will just have to be OK. Just a fun project for myself so I can play around.

Husqvarna 353, carb issues, found debris by inlet needle, cleaned and reassembled, back with the living again.

76.5cc poulan. Was selling this but like to pull down and check them.
Didnt pass my inspection aka crank bearings so at least I didnt ruin a NOS topend on it.
