Welding stuff! Fixing things. Cold.



Nutcracker Progress


I continued to practice my welding skills on the nutcracker build.    I am, slowly, getting better I think.  I am still using .030" flux-core wire in my welder, so technically I am NOT doing MIG welding.  MIG requires a shield gas.

Handle/lever was added - its now functional!

Here I still need to chop off the tail and figure out an option for the clamp.






Video showing the nutcracker in operation!



Throttle control for the backhoe

It's still too cold to even consider starting the backhoe, but I figured that I could still try to fix the throttle control.  As you can see from the pictures below, the cable broke off from the control lever.

Well, long story short - the throttle cable evidently got some water inside of it and froze - I couldn't move that cable at all!  I considered forcing it, but I didn't want to risk breaking that cable anymore - it's too close to the point where I will need to replace the whole run  of cable if it gets any shorter!



Not much cable on this end to work with!


There is some cable length at the other end I could pull through - if  the cable wasn't frozen in place!


The next day, however...  it warmed up enough for me to pull a little bit of cable through - enough to get a hold of anyway!

I managed to straighten out the cable enough to get it through a hole that I drilled in the bolt shaft on the throttle lever.

The cable is secured in place on the throttle lever by two nuts I tightened against each other

I am still afraid to try it out because its cold and that throttle cable is brittle!  I am also thinking that I should put some loctite on those nuts to keep them from loosening from the vibrations.

Examining some of the scrap walnut


I had moved some of the scrap walnut from the floor and cleaned it up and temporarily restacked it on the sawmill bed.  I brushed it off good too.  I think there may be some good wood in some of this stuff! 

There is a fair amount of this walnut 

There will be some waste, of course, when milled into a usable condition

Here is a piece that I trimmed and put through the planer.  It actually looks quite nice!   Very nice wood to work with as compared to oak and maple!  I ended up giving this piece to friend at work who helped acquire and mill this wood.  He has considerably more carpentry skills than I do.

Post soaking continues


I have been trying to get one post a day through the copper naphthenate bath.  I like to let each post soak overnight.  I think that some of the ones I did when it was real cold out may not have absorbed as much preservative as they need.  I may put them back in for a while.

Six posts left to go!


I am not using as much treatment chemical as I would have thought.  The wood only absorbs so much.  I have used about 1 gallon of the CuNap concentrate so far.  I did mix mup another batch this weekend.

Welding table - ideation to early build in one day!


In preparing for the welding I will need to do for the belt-grinder build, I decided to just make a welding table.  I determined I needed one after looking at the damage my tablesaw table was taking from my nutcracker build!  

I found pretty much everything I needed right in one place - my garage!  Actually sitting next to each other!

Looking around for ideas and scrap to work with - I found this old packing frame from my woodmaxx woodchipper!

Old shelf support brackets (I think) from an old store


Just need to get it out...

After using metal cutting chopsaw to liberate these square steel tubes

Just need to correct the height and attach those tubes and its done!  Next weekend will see it done!


Belt grinder supplies are in!


I have everything (well most everything) I need to build the belt grinder!  Now the hard part...



That's about $200 in metal there!  Not to mention the shipping.  Ugh.
2 HP electric motor!  3-phase, sealed (TEFC)   Bugger is heavy.

Tractor and UTV off to be fixed and maintained


Now that it is snowy/cold/icky outside and I am not in dire need of my tractor and UTV, I decided to have them serviced.   Hines came out Friday and picked them up just before the rain started (as it started actually).   They got them both on the same truck.  They were packed in tight though.

We had to push this down to the truck bed from the garage - fortunately its all downhill!  They used a winch once it was this far.

The tractor was able to back right up onto the bed.



Off they go!

Family x-mas, and COLD weather continues!


Family x-mas


We got together on the 6th of January at Mom's house.  Unfortunately, Connie, my sister, was unable to attend.  She had come down with a bad cold and had to cancel at the last minute.  The rest of us got together and had sauerkraut and pork.   Lots of cookies too.  Too many cookies.  LOL.  Ah well, its tough time of year to be on a diet!  I was doing pretty good.  I was down to 245 just the day before the party.  That's 40 lbs down since October!


COLD


The weather is in it's 2nd week of  single digit temperatures.  The doors on the country house where actually sticking due to ice condensing between the doors and the frames!   We had a dog-grooming scheduled for Saturday morning, but they rescheduled for the 13th due to the cold weather.  I guess it was considered too dangerous for some of the pet-owners to get to the shop.   I have been doing work in the shop as much as possible to avoid the biting cold winds.


Welding practice and Nutcracker build

Last week I was just running beads and welding silly stuff together to practice my MIG skills.  That was ok, but it got boring, so I decided to see what I could find on Instructables for small welding projects.  Well, I stumbled on a nutcracker design that sparked an idea.   I designed my own, similar to the one that was presented but using my old square shelving tubing (of which I have a LOT).  I scrounged around a bit and found enough steel to give the build a try.  I am winging a lot of it.

Since the walls of the tubing is thin, I decided not to drill holes into it, which would further weaken it. 
Instead I welded the pins to the surface of the tubing.

I made tabs of steel and drilled holes through them and welded them to the sides of the tubing.  These tabs are thicker than the tubing walls and provide a better bearing surface.

My welds are improving.  Its still damn difficult to see the weld while its happening though.  My breath fogs the helmet!

Oh.  I got a new welding helmet too.  Its auto-darkening, and unlike the old one, it seems to work more reliability.

I have a concern that maybe I didn't leave enough room between the hammer and the anvil to fit a nut in!  



Here it is with the pusher rod attached and forward

And with the pusher rod pulled back.



I have 4 more tabs to cut and the main lever rod to put in place.  I tried to get it done Sunday, but it was too damned cold to be outside for long, so I decided to just wait.  It's just for welding proactive anyway.


Post wood-treatment continues


I was only able to get another 2 posts done since we weren't there very long this weekend.   I didn't even take the tractor over to get the remaining posts to saw to length.  I did pull them out of the stacks though,  They are ready to grab and saw when I get there this coming weekend.

Another post is in soaking.  At these temperatures I think it takes longer to soak in!  I let each post sit overnight when I first put them in.  Then at least 4-6 hours when I flip it over.  Sometimes overnight for the second side too.

Seven (7) posts done by the end of this weekend!

The variety of wood is quite apparent here!

The darker wood is red-oak.  I am not sure what the lighter wood is - maybe basswood or poplar.

I pulled these seven (7) posts out of the lumber stacks to get ready to trim them to length.  It was just too cold to go and trim them this weekend!


I still have two (2) posts already cut to length and ready to go yet anyway.  There is also one soaking in the trough.  So I have 17 posts.  I need at most 13 for the fence, and 2 for arbor post replacements.  I might replace other arbor posts though, since I am betting there are more that will rot off soon.

Planting Trees! More lathe-attachment work.

Arbor Day Trees arrived!


I was a bit surprised that they arrived in mid-December.  The ground could well have been frozen! Fortunately, it wasn't and I was able to get out and plant them.  2 Arrowwood, 2 oak, 1 birch, 2 crypemrytle, 2 ornamental crabapple, 1 dogwood, 1 colorado blue spruce, and I forget the rest.  I think I had more then was account for in the invoice.



Added the 2 new crabapples next to the others.  I added the new crypemurtle and hawthorne to the end of the row of exiting crypemrytle and hawthorne.

I put tree protectors on them because I am afraid of the deer eating them off when (if) they sprout out in the spring.

Replaced one of the arbor-day dogwoods that died earlier this year.

I put the 2 arrowwoods next to the driveway.  I will probably put up some kind of protection for them.



I put the river birch on the wet side of the hill near the hazelnuts.  I hope I don't regret this later!

I put the oaks and poplar out on the steep part of the field.

I put the spruce out near the other spruce and pines.  This sapling looks in VERY bad shape!




Deer damage to the trees



While out planting the trees I didn't notice any damage, but when I took a survey later I looked more closely.  The locust and spruce trees had been hit pretty hard by the deer!  Lots of broken limbs - even a couple of the spruce were pulled out entirely!  Now, the spruce that were pulled out where probably dead anyway, but there were a couple that took damage that were trying to grow.  I will just have to put cages on the spruce I guess.  But what about the locust?  I cant put cages on 100+ trees!  Electric fence maybe?

I noticed many locust trees had branches broken off like this.



This spruce was pulled out entirely! 


This tree had some life in it - but i don't know that it will survive now.

Closeup of deer damage

You can see here the deer scraped the bark off this tree.  This one is probably dead anyway though.



They broke the top out of this one, but there is still some life as seen on the lower limbs there.  


Sawmill-Lathe-attachment progress



I cleaned up the glue-up panels and sanded them a bit.  They are a bit wavy, but not so bad for what I need them for.  I bought some red paint just because Im tired of black and white would show too much dirt.  Also, I just liked it! LOL



First coat.  Kind looks neat because you can see the wood grain through the thin paint.

I completed the head-stock with its motor mount.  I masked off the bearings and motor mount and painted it gray.


I dinged the jointer blades straightening up the boards of the headstock.  Grrrr.I have more on order.  

Second coat!  Looking redder now.

painting these to keep them absorbing water and deforming worse.  Also, its pretty!


Second coat for head stock.  

Looking good.

Probably give head stock and glue up panels one more coat.  I still need to complete the tailstock and paint it, as well as painting the bottom of the head stock assembly.  Then I need to attach the head stock assembly to one of the glue up panels.  Still need to weld the hub to the big pulley.  Also, still need to make the faceplates and attach them to pulley hubs.  The pulley hubs will be made by removing the pulley portions either by using the metal lathe (assuming I can get the wiring figured out) out by grinding it off.  I will weld the pulley  hubs to the faceplates.  I practiced some with the welder this past weekend with this in mind.

Dialed in the current to use with the 1/8" rods.  Looks a bit rough, I should probably practice more!

On the other hand - this weld is super strong!

I thought that this metal piece represented the material of the pulley and hub, but in fact I think pulley and hubs are thicker.  Maybe need to adjust the current more...


Lathe-motor wiring



I continue to try to figure this out!  I decided to take pictures and investigate more.

Six motor wires

Six wires to switch

Wire mapping notes

After lots of analysis I came up with a sheet of VOM tests that I can apply to the wire leads to determine what is going on without having to remove the motor from its mount.
