Mack Muster 2026, 60 years of the R model

This year is 60 years of the R model Mack 

So it's time I at least try and attend a show, I'm not a show type of person but figured I need to push myself out of my comfort zone just a bit some times

So here goes nothing, read bellow 


Well the mess is in full swing nowMrs Mack is up on blocks, wheels off, exhaust off, bull bar off Spent way way waaaay to much on partsHave a week off work, it isn't gunna be long enough, need a monthMy boys down from QLD and he is chief in charge of polishing the bull bar as I apparently can't polish to save myself I have lost a important part of new exhaust system I ordered years ago Spent hours searching for must have item that I have carelessly missplaced or as I would suggest, put some where for such safe keeping, even I can't find itLost a couple of days visiting a friend who is having a bit of bad issue with a brain tumor, thats a fair bastard of a thingAnyway some unexciting screen shots from a less even exciting video I might actually get to edit and finish one day  The boy on his phone, porn hub no doubt
 

Shinier than the top of my head on a hot day

 

Exhaust is well worn

 

 

 

And squashed a bit

 

Mrs Mack is up on blocks

 

Off to Echuca this morning to get a magnetic drill and broach set to drill holes in chassis for mounting exhaust gantry 

Oh the mess is gunna be huge

Going try and fix the 5 billion airleaks and re plumb the air system

Got gazillions of meters of hopefully the correct colour and style of air line, olives and air fittings to solve this mess 

plus so much more

Rained half the day today, so off to Echuca for a Mag drill and other supplies 

Stuck about in the wet and sticky clay this afternoon 

My grand achievement for the day

Got my new to me after loosing (missplacing so safely I can't remember were) 4" - 5" reducer for the exhaust

4 inch turbo outlet and putting a 5" exhaust on 
So we, my son Jack'0' and I had our virgin run on a bead roller and made a 1/4" step roller, roll a 60° flange on each end, this bolts to the new to me exhaust brake 

Then grabbed from the selection 90° mandrel bent 5" elbows my first victim 

I soon realised that there just wasn't going to be room to fit the elbow in between the fire wall and exhaust brake 
Oh and I'm fitting a exhaust brake as well because as good as the Dynatard on a Mack isn't, we can always do with a little extra stopping power

So I promptly chopped the new flanges off the reducer as short as I dare go, minus a little bit more 

Then re rolled flanges on the new "how short can you go reducer" and refitted the exhaust brake and reducer 

I then looked at the elbow/victim and after much discussion with Jack'0' I ignored all of his advice and protests and cut away with the grinder

Would you believe it, it wasn't right

So next victim in site and more guidance from Jack'0' ignored, I sliced away merrily 

This result was much better and not as diabolical a egg shape as doom and gloom Jack'0' suggested

So thinking this might work okay we rolled a bead or ten and flattened these out to form  flange

It almost didn't fit, but if we made the flange sharper on the bottom and less on top we could adjust the down pipe slightly so it fitted fine

So after a afternoons work and lots of discussion we have a exhaust brake fitted and engine down pipe, Jack and I were certainly pretty impressed with our results

We have a 5 inch down pipe were it shouldn't fit and a Jacobs exhaust fitted to possibly assist the not so impressive Dynatard engine brake 

 

I know it doesn't look much but struth, it was a lot of work for a couple of rookies using the wrong gear

Very nice....  I've often wondered about geting a bead roller thingy.

Will it survive the turbo heat? 

I think so, it's a propper flange, about a half inch

Just like a factory or exhaust place
I can't think of any reason it won't last

The bead roller die set was to roll a 1/4" step on
But we worked out, a couple of steps and then roll the steps on the flat roll bit and I end up with a nice flange that can be adjust to suit what angle I choose

Cut off flanges to show what we ended up with
