Jacq's Logging Project Discussion

[marc_reusser]

Great work Jaqc.  I really like the tilting windows, and your use of cherry wood is very interesting...it stains up beutifully.

The corrugated question is a tough one to answer....as there are several ways this might have been approached, depending on the builders choice.....and the sequence in which this was built (which likely would have been siding first...then roof.  (unless the roof was fully sheathed..then it would have been roof sheathing, siding and then corrugated...but agsin....all depends on the builder of the period)

The "best Practice" and likely the most common for construction would have been one of three ways:

1.) Install/fasten a bent piece of flashing...say 6"-8" on each leg onto the the studs/framing where it meets the rafters...and just high enough above the rafters to fit the corrugated under later. Then sheath the wall...with the wall sheathing and battens covering the part of the flashing nailed to the studs/framing.

2.) After the wall sheathing was installed...but before the battens are applied....the same bent flashing strip is nailed onto the top of the sheathing...probably with some asphaltum behind it to act as a seal gasket...then another brushing of asphaltum to seal the top lip/joint of the flashing at the wood.....then a horizontal trom board (the same thickness as, or just a slight bit thicker than, the battens would be applied along the bottom edge of the wall, covering most of the vertical section of flashing...and also covering the joint between the flashing and sheathing. The vertical battens would then be cut to sit/stop tight against the horizontal board

3.).....and this is what I woud ASSUME to be the approach they would take [as the previous two above are much more "finished" type of work.....the type found on typical residential or commercial work,...where appearance was more important, and money was spent on this type of detailing]......I believe they would take approach #2....but not do the horizontal trim board to cover the flashing....they would simply run the battens down onto the exposed flashing (I have seen this detail on less finished/expensive structures, and farm/utilitarian type structures, of the period).  I will see if I can find a photo that shows this.


....then  of course there were a myriad of other ways this could have been haphazardly done or improvised.....but I don't think that would fit/math the effort and quality of the rest of the mill construction.

Very nice!!  The windows are they wood or from Tom?
Glad you showed pictures with the roof rafters just showing really a nice birds eye view of what's going on inside.

Jaqc,

I dug through a file of old photos of barns (since they are somewhat sim in approach to external construction and framing and finish materials, as the type of sawmill you are doing).  Sorry for the image quality, but I had to substantially enlarge the images so the areas of interest/discussion would show.

In image 029 below, the wall sheathing seems to be over the flashing (as indicated by the ragged/uneven bottom line of the boards)

Image 038 also shows the flashing behind the wall sheathing

In 053, they seem to have simply bent the metal up over the sheathingand sealed the seam with asphaltum...looks like they may have even bent it over the battens as well.

In 059 it look like they are using rolled asphalt roofing for flashing, the edge of which has been wrapped uo the wall and then held in place with the board. ....this detail though is an improvised/later repair.

More to come....

In image 041, the flashing seems to have been installed underneath the sheathing.

In image 060, the flashing has been installed over the sheathing...and under the battens.  Note the like of asphaltum sealer at the flashing wall joint between the battens.

In 062 the flashing is installed under the sheathing (again note the uneven bottom line of the boards)

In 079 a piece of metal flashing or flashing made out of rolled asphalt roofing, has simply been bent up over the shiplap siding, and sealed with asphaltum.


Hope these were of help/interest.....as you can see you have some options to play with.

Jacq,
Wow, nice work!  I just found this and have not read everything.  I have been working on the modeling the Hume Mill and have a 2D cad drawing and HO model...  I would love to share some info with you.

Here are some photos for a few years back.  The pillars that the dam stood on are not large, just the size of the timber that stood on it.  There is a large concrete block that I may have been for the saw and other than that there is really no other concrete left from under the mill.  The mill was built at the same time as the dam.  And all the supplies were carried by wagon 60 miles through the mountains.  For the dam, only cement was haled to the site.  Granite was quarried, sand was found in the stream, 7 miles of cable and lots of RR track was used to reinforce the dam.  So I guess they did not want to waste much concrete for the mill.  But wood was plentiful! 

I look forward to seeing your progress!  I am so glade I found it.  You can work slow, since I have months of reading on this topic to catch up

More photos from around the dam.  This has foundation of boiler house.

  Is it normal practice that the corrugated roof fits under the wall parts? Or is there a metal flashing?

Jacq,
I have a lot of photos of the Hume mill, but none give that detail.  I don't see flashing and don't think there was any.  But I think the board and batons were put on first.  At least in The Felled the Redwoods page 102 see the left side of the filers room the batons are on prior to the corrugated roof.  I assume that if there was wind it would leak.  They didn't have to worry about the computers getting wet   And the overhang of the roof above was a few feet...

Hi Matthew, nice to "see" you again!

[jacq01]

 
    Marc,  thanks for the corrugated details. Decisions, decisions, decisions..................... Time to take out the bike and think about what, how and when.

    Matthew, welcome.  I have seen the Hume Lumber site.  Some nice info. Also the photo's of the concrete remains are helpfull. 
    The photo of the mill under construction shows the roofsheating protruding beyound the filers room wall.
    Other photo's do show this part not being there anymore.


   All rafters are on.   
   I have been advised to seek asap professional help. My wife is checking our health insurance or it is covering specialised therapy.


   

   The roof finished. The tree on top is hardly visible 

 
 
  Tomorrow with the correct light, I'll take photo's showing how it breaks down into subassemblies.

Holy Rafters... Jacq-man

You are my hero....   

It sure looks beautiful jacq.
I am truly enjoying this project of yours.

Absolutely beautiful framing Jacq. I'm sure the flashing could be done a variety of ways on the corrugated roof to be prototypical but to be correct, always keep in mind the water lap. The flashing should go behind the siding. There is a flat to corrugated piece of flashing available to roofers just for this purpose.

Yes you are correct!  I guess the builders change the design as they built! 

I see that you have followed the Hume mill in many ways.  I wonder why you did not put the second skylight window to the right of the filers room?  And maybe you state it somewhere (I haven't got to read all the posts), but obviously there was a ground floor under the floor that you built.  What is your logic in leaving it out.  Do you assume there is a basement in areas where needed (i.e. the band saw)?

I looked more at the picture from They Felled the Redwoods page 102.  I noticed that everywhere the people are sitting in front of the mill was temporary!   Also I noticed in your mill and it seemed to be confirmed in the same photo that the mill has no internal supports.  Wow!  That is a 50 foot span!

As you can see I need the professional help.  So when you find someone good let me know!

Chuck, thanks!  It is great to see you here too!

Simply beautiful.

Nice that you kept the tradition of the tree.

  As promised:

 

  saw floor and posts.  This area still needs to be finished with corner stiffening, sawmill equipment, stairs, details, details,
  dirt, sawdust, bark etc. etc.

 
 

  Roof assembly added.  The roof fits between locators, keeping posts upright and roof in relative position to each other.


 

  Roof is a self supporting structure.  This enables easy finishing of with details like tension rods, nbw's,  lighting cables with insulators,  passage to filers room, trimmersaw operators platform, etc, etc,


 


 

  filers room roof and skylight with roof removed, showing the recess in main roof.  This enables finishing of filers room interior and outside walls.

 

  Filers room roof and skylight assembly is also a seperate unit.


 

  And all parts assembled again.   Without gaps 

  Matthew,  the ground floor will be part of the landscaping on the module as this will contain all it's concrete piers and foundations embedded in the rockfloor. 
  The mill is not an exact copy of the Hume mill.  The filers room is wider to enable sawband from main rig and resaw to be lifted directly into the filers room.  The layout is a mirror image of the Hume mill so I could use material I had already.
The layout is for a very large part based on information I received from Marc,  my interpretations of the books "They felled the redwoods", " Pino Grande " and sawmill related patents from the period that these mills were built.
  The diorama will definitely include parts of the Hume dam, boiler house and engine house.

Follow this thread a while now, I had the opportunity to see this project last weekend at Jacq's place. The pictures I 've seen here of this project are great but to see this mill live is even greater.
Keep up the good work Jacq and thanks for the invitation and the lots of info you had given to me. I really have to get more info before building the new mining layout.
