Another SP-125/101b build

[cpr]

Not sure what happened, but here is post #5 reprinted as it should have looked in order to maintain the storyline.

Done.

Next, I have to get the passage drilled for the manual oiler rod. It goes where the hole-to-nowhere is in the stuffer. I was VERY nervous when I first did this on the MC-91. I figured there was no way to fit it all in, but it works.

The oiler rod passage does slightly interfere with the chain-guard/engine mount boss, but when assembled it all works.

The next bit is going to take awhile. I have to get the rear AV mount to attach to the head. You can see the 2 holes in the shroud of the CP block where it goes and nothing on the 101 head. I'm leaning towards aluminum block on the outside (leaving the 2 gussets) and another block between fins 1 and 2 and TIG welding them in. Then drilling and tapping the mount holes and drilling out and counterboring the block between the fins for the head bolt.

I have a shopping list of small parts to get. This saw will use a BDC carb on a sloper with the bottom of the airbox cut away to fit it. For exhaust I have a GEM header that comes back and down at a 30deg. angle for now. I may change that for the "sleeper" look.

Speaking of the BDC, here it is next to an SDC20 that came in the late-model Super 797s and CP-125s. I think I figured out what the letters mean: Small Damn Carburetor and Big Damn Carburetor :tongue2:.

It turns out that there aren't 4 of us building saws like this, but 5.

My 5 year old son patiently waited for the end of the Lions game and then we headed to the shop for an hour before supper to start working on the the blocking in the cylinder head to receive the rear AV mount.

Christian with the marked out blank and the 101 head.

Hand radiusing the shoulder.

Hacksaw relief cuts for the 1st fin gussets.

We finished the top block, but ran out of time to do the second one. I'll to that tomorrow night and attach them. For working hard, he demanded a portrait with the 791R that he could take to school tomorrow. Who am I to say "no?"

Updates will be sporadic with the holiday, but we ought to have this one done well before Christmas.

Looks great, Now that i am more familiar with
the SP chassis i see the two holes that must be
drilled for the rubber bumper.
Are you going with the BDC 14 pictured. I have a big
BDC that i think i will try on mine when the time comes.

Thats awesome!!! Cant wait until mine can go out in the garage with me. Wife might let me spend more time in the garage too.......Double bonus.

 

[cpr]

I'm tickled Brian... Crappy part is it'll be 10 years yet before I get to see the smile on his face when he runs it.

Yes Lee, that carb's goin' in there one way or another.

 

[leeha]

You know with your son helping out that you will
never get rid of those saws. I think it's awsome you
have him helping out on nice projects. Better than
sitting in front of a TV or computor games.
Next he will be on AS with the rest of us nuts.

just saw a segment on the 'auction hunters' show on spike where they found a couple of 101 hot saws in a storage unit. the expert they took them to said one was built by a terry ives. i was surfing and didn't catch the guys name but he ended up buying them for $4000. the one had dual hl's and a pipe .they ran it and it was impressive. may be on the tube.

episode 224 on the spike.com- about 12:50 into the show

Terry Ives is about the best engine builder in the business. He's one of a handful of real legends in two-stroke engine tuning.

And he has my 101 block right now Hopefully he doesn't declare it DOA!

That was George Harrison from Grassvalley, Ca. Those were his saws to begin with, but Terry Ives did build them. When this TV thing came up, some guy came looking for saws here at ASite. Darin gave me a call about someone looking for a hotsaw to hide in a storage unit. Didn't work out because he wanted a hotsaw that hadn't been seen on TV. My hotsaw had been in a movie and on an episode of Monster Garage with Jesse James.

Very cool, but pretty easy for us to see that the whole thing was staged. It is worthless if it won't start? Forking over 4 grand for two old hotsaws?

 

[turtle561]

i recall the post looking for hot saws. when they first showed the saws on the show they were chainless, when they ran it, it had a shiney roller nose on it!
so how is chico these days? i went to the college there in the 60's. loved the town and countryside, especially the foothills up into the mountains. had a friends up in sterling. can't imagine what it must be like now.

I just went back and watched that show, when they first found the hotsaws there was a mac and what looked to be a Stihl 056 with a pipe. Yeah, it's staged......

I recognized those saws right off, I pulled up some of my old videos to prove to my wife they were George's all along. i've been running against those saw for a few years. George would have bargined a lot better than he did on that show.

 

[parrisw]

That's quite the joke that they are staging the show, not surprised at all.

 

[cpr]

Well, there's 20 minutes I'll never get back. I love how a piped 056 turned into a second 101 at POS, but when it was time to find out which one actually ran, it was a 3rd 101. That was the only 25 seconds worth watching...

 

[cpr]

Still prospecting for some parts.

Anyway, I got curious about my RM-built 101. Knowing it was ported, I wanted to see just how "ported." Turns out, it's pretty mild, not a windowed, chopped, channelled freak-job. The boost ports are squared a little and the transfers knife edged on the webs and radiused. They're shaped to direct more towards the roof and opposite wall than stock, but not radical. What worries me is that the exhaust has been raised a little.

So here's where I'm at. Since this will be a BDC breathing, short-bar (relatively 28-32 if I can source one), cookie monster, should I try it and save the stock port one for a 797 install like I had originally planned?

Or...

Save it for trade bait to get a stock port one?

I defer to those who've been there before me and I think I know your answer, I just want to hear you say it again.

 

[leeha]

Ruuuuuunnnn It. You will never know till you try it.




Lee

 

[blsnelling]

How much has the exhaust been raised? Terry Ives told me to raise mine .050".

 

[cpr]

Haven't measured, Brad. It's less that that.

In she goes...
