so waht ya doin today?

[KeithB]

Finished up a batch of parts, the first batch we ran back in 2017, before we moved to our current shop. It's a rivet-in-place bearing housing that is anchored to the wing structure of a light plane and provides a hinge point for various control surfaces. It's made from 2" diameter 2011 aluminum bar stock. The first two steps are to turn both sides on a CNC lathe and then drill the rivet holes on a CNC mill. The last step is to insert two small ball bearings in the housing and crimp the end over to retain them. I made a tool to do this on the manual lathe. It has a wheel with the proper size radius machined into it. It is made from A2 tool steel but I haven't hardened it yet. Probably don't need to and I wanted to work out any kinks anyway. It seems to work fine.

The part is held in a face collet (which is also used for the second lathe operation and the CNC drilling operation) and is turned at 350 rpm. The tool is manually fed in from the end along the Z axis, when the wheel makes contact it starts spinning and rolls the end of the part over, effectively crimping the bearings in place. A few seconds with some Scotch brite pads to clean off any tool marks and its done.

Part in collet prior to crimping. The crimping wheel is made from A2 tool steel, I was able to machine the proper radius in it with High Speed Steel tooling since it is unhardened. I could harden it, A2 is easy, but I don't really think it's necessary.


I have a video of the operation but I'd have to make a Youtube vid of it.

I didn't have a single range rod with 10-32 threads, so I took a 5/16" one with fixed handle, chucked it in the lathe, faced it, drilled it out with a #21, counter bored it, and tapped new threads. Made a 47 caliber jag/ball seater out of a .50 while I was at it.



Also turned this



Into this

 

[creosote]

That's one heck of a transformation. How old do you reckon that horn is?

 

[Ian]

No telling. All the raw ones I've seen for sale are crusty and very dried out like this one was.

Finally got to the range to try out my first suppressor. I put it on a 22 with a bushing as it is a 30 cal can. I'm quite happy with it.
I intended to try it on a 300bo, but didn't feel comfortable loading ammo after having a bit of an accident and getting a pretty good knock to the head. I thought I was recovered pretty well, but every time I fumbled with something (cold fingers...yeah, that's the ticket, yeah.) other guys were there to help almost instantly. Obviously, I'm not quite there, as I realized I had several volunteer nurses watching me. That is both embarrassing and comforting. Been knocked in the head quite a few times in my youth, but don't remember it taking this long to get back on top.
Anyway, I only fired 10 rounds, as hunching over the bench and tilting my head up to the scope was uncomfortable. Guess I need a few more days..

Concussions should not be taken lightly Tom.
You might want to consider seeing a physician, especially if you are still fumbling things come Monday.

Stock duplicator.
You'd think a person selling a machine for 7 grand would take photos that weren't totally fuzzy.

If a guy was looking for a sideline and had access to decent wood and some patterns that isn't a bad price at all.

Still waiting for power.

1 of 1334 without.

NAEC power outages fall below 3,000

Progress continues as crews work to restore power in the Twin Lakes Area. As of 4:40 Friday afternoon, North Arkansas Electric Cooperative was reporting a total of 2,997 members remain without power. According to the cooperative’s outage

New update: As of 6:40 Saturday morning, the cooperative still has 285 outages in Baxter County, 270 in Fulton County, 87 in Izard County and eight in Stone County.

Yeah that sounds familiar.
We live on the “fringe” of what passes for civilization in the great white north and I know you are remote as well.
Last time we had a major power outage was last summer after a freak wind storm. Two thirds of the interior area around Fairbanks was out because of trees being blown down and taking out power lines. The power company worked its way outwards from the population center to the fringes. We were not last but I think we were about 2,300 still without power. Having a small forest fire in our neighborhood did not help at all.
Took 5 days for power to be restored.
Our Kobota 12 KW diesel just chugged along.
We normally will get a power outage 2 or 3 times a winter with a major outage lasting for extended periods of time about every 4 or 5 years. These outages seem to last from 2 to 5 days.

John has the Generac 20,000 kw, exactly the same unit as my 22,000 kw. He was without power for about 15 seconds when the generator fired up and he hasn't missed a beat.

 

[Glaciers]

Yeah the Genererac systems are really well thought out. I used to sell and install them. The problem for me is having to have an underground 500 to 1000 gallon propane tank. I have a 500 gallon #1 diesel fuel tank for the heating system in my shop already so it was a no brainer. No Natural Gas in most of the interior of Alaska.Besides I got this 20 year old genset for $3,000 with only 3 hours on it.

Edit: besides I like diesel generators. Just make sure it has fuel, crankcase oil, coolant and you’re good to go. Besides in the winter time which is generally when we have an outage, it heats my shop. It is set up inside.

 

[Winelover]

The Generac has been running continuous for 80 hours. Checked the gauge on the 1000 gallon buried propane tank, yesterday AM. Was reading little over 75% of 900 gallons. Approximately 675 gallons remaining. Used about 225 gallons since fill up in July. Maybe 25 of those used, prior, were from weekly generator exercise, gas clothes dryer, range and BBQ grill. I average about 100 gallons per year when we don't have power failures. Longest power failure was four hours, several years ago. Most are just nuisance occurrences.

 

[Glaciers]

Well grandson Cole and I went down to the hardware store and picked up a gallon of the paint of his choice (color) with the criteria that it was the cheapest exterior paint on the shelf.
Got him lined out and he did a good job mostly by himself.



Personally can’t say much about his choice of color, but…

Now I’ve just need to make a door and 3 window coverings.

At what temperature does diesel fuel start to gel?

 

[Glaciers]

Yeah the Kobota can use about 25 gallons a day under full load but normally it’s about half load which suck’s about 12 to 15 gallons in 24 hours. Only heavy loads are the electric dryer and the sauna. Most of the time it’s loafing.

 

[Glaciers]

At what temperature does diesel fuel start to gel?

#1 heating about -64 below. Only had that problem once. Just go out with your small propane torch and run down the copper fuel line every couple hours.
JP 4 will jell about -55.
#2 diesel about-10 to -15
I burn #1 year around.

 

[Rick]

I topped off the propane tank the week before Christmas, December was quite cold for here and I am heating the house with propane. With the snowstorm predicted and the possibility the generator and heater could be running I topped off again last Tuesday. 5 weeks and the only propane use was the heater, it worked out heating the house to 3 gallons of propane per day.

 

[popper]

Looks like a color some in my neighborhood want to paint their houses!

 

[Kevin Stenberg]

John with a door that short is it going to be a kids play house?

 

[Winelover]

Just got email from the coop..........power is back on. Had to go outside and make sure the generator wasn't running..........can't hear it from inside the house. Especially, when music is playing throughout.
