Mall 7H bar: 36in + 48in = 76 inches???

nstueve · Mar 13, 2013

Ok so this definatly deserves it's own thread! I'll link it back to the Iowa Spring GTG II thread later...

The back story is a local shop of mine restored a Mall 7H to put in the show room but the bar was quite pitted and a little too short and stubby to be "impressive" at 36 inches. So after brokering a couple deals it falls to me to locate a bigger bar that isn't too expensive for the saw. So I steal there 36inch bar and make some calls and found a 4ft bar that was delightfully droped off to me across the street from work! Convenient and cost effective... 4 ft still wasn't "blowing my mind" so I enlisted the assistance of my good friend Shaun!!!!! Shaun's master plan in action below....

Clean bars... Mitch hold the air hose! :msp_razz:

Chop the bars up! Bad Shaun... No PPE????

That's better!

Weld that big SOB together... And a beautiful tig/mig job it was!

Many steps later (shaun may have more grinding and groove cutting pics to instert here...)

Finished product! Now that will look bad arse on the Mall 7H hanging from the ceiling as you walk into the saw shop show room!!!! As soon as I pick it up, and get the scratcher chain fitted to the right size, I'll be back with the finished mounted product!

Now I wonder what 8-10hrs of shuan's shop time is going to cost me...

Huh... bet if I left the scratcher chain he probably would have fixed that up for me too... Nuts should have left more for him to do... I know he doesn't have enough projects... :wink:

Hey, thats neat! You are going to actually go cut up some big logs with it, right, before it gets hung up forever?

Three things need to happen for that bar to be used before being hung up.

1.) find rivets to make the two chains into 1.
2.) someone needs to sharpen the scratcher chain... NOT ME!
3.) someone needs to bring a Mall 7H or compatible saw to Hedgefest.

Pretty sure Ray has one that could race it up there in Newton.

It's hard to get pictures working on it alone but I finished grooving it last night. Its a big pita to balance a bar of that size on my grinders 14" table. My arms are tired from holding that thing up for 2+ hours grinding the bar groove in deeper all across that whole bar. The next bar groove grinder I build will have a larger table and more power.

The bar ended up at 78 3/4" from tip to tip.

Now that is impressive. Man is he ever handy. I am lucky enough to have some friends who are able to do that sort of thin, and am amazed at the ability that some have and just plain baffled as to how they acquire that much skill. JR

going to clean the scratcher chain this weekend. I smell some boiling AFT in my future, and a ton of wire wheel grinding hours! ugh :msp_sad:
I might try that new WD40 rust dis-solver if I can find some...

VERY VERY special thanks to shaun for taking on such a tedious task for me. I can only imagine how hard the .080 gauge groove grinding went!

I believe there will be some Malls at the Iowa GTG if I can get the chain finished in time. Unfortunately I can't take the refurbed Mall from the shop.

Nathan, do you want that SOB clear coated or do you think they'll want to paint it some Mall colors?

thin coat of wild dog 40 sounds good to me for rust prevention... they can do what they want with it later. Try to take it easy on you from here out...:msp_biggrin:

PS: need some tips on what to do with that honda gx200 for a little more power when and if you have the time to send me some ideas...

Different cam and valve springs, then a lot of machining/porting to the cylinder head. Then strap a Tilly 334A and fill the tank up with alcohol. :msp_w00t:

yeah ok... since it's bogging my NT Northstar power washer, I need to pour tons of cash and YOUR machining and porting time into it??? think not... Need modest power bump to keep engine from bogging under load is all... I could probably clean up intake/exhaust with dremel and muff mod easy enough...???

Not a ton of cash, just a little, or chainsaw parts and home brew.

Just bring the head over. Porting and a decent valve job make a good difference. Then about 0.1" off the head and they finally have compression. If you want to go over 5k RPM you'll need to change valve springs, they're $15. Probably advance the timing a little but I use the dyno to figure out how much.

I saw old two-man saws used in the 1970s, sometimes there were logs that needed 8 feet of bar to buck.

hmmm...another work day at Shaun's??? I'm game as long as we leave the JW Black in the cupboard! ugh worse than this :check: the next morning...

I have plenty of my own projects to work on... I'd leave that one alone for a while.

yep... maybe mid summer if I get around to it!

As impressive as the bar work is (and it IS), my eyes went to the Dirt Late Model(s) in the background.

WooHoo!

if you think those are cool you should see some of the other stuff they have around that shop. their race car trailer is beyond SWEET!

Some of the sweet stuff shaun works on doesn't get seen a lot on here... I need to go find his YouTube channel and become a watcher/member so I can see more of what he does!

They make good shop ornaments in the winter but now it's only 2 weeks till the first race. One car is done (just waiting on an engine), one needs an oil system and engine and the closest one is an old car that should be turned into a spec motor weekly racer.
