Off To The Rack With You!

The alignment rack, that is.

Or in my case, a set of graduated fixtures and holders so I can measure and adjust the camber, caster, and toe of the little R/C car.

The fixtures bolt to the stub axles in place of the wheels, and you place the fixtured car on a flat, level surface, and read the scales.

This poorly lit shot shows the toe-out to be 1*, per spec to start with. Toe-in/out is adjusted turning a little turnbuckle on each side's steering linkage, just like a full-size car.

This shows the left rear to be at -3* (negative) camber, and the spec is -2*. It's also easily adjustable with a turnbuckle.

And the left front shows -1*, also out-of-spec, but also easily adjustable.

So now I have the suspension dialed-in to the recommended settings to start with. Might need a toe adjustment, or perhaps run a different camber setting on the front and/or rear. I've done this before with full-size cars, and the principles are identical, so I understand what the settings do. What I don't understand, yet, is how they relate to a 1/10th scale model, this particular one, and the track I'll be running on. Still have a lot to learn, and I expect to be at the track in a week or two.

The window masks for the body have been cut and trimmed to fit:

And after cleaning the inside of the body again, they've been applied to the window areas inside the body:

Since it's forecast to be in the mid-60's tomorrow, it's going to get painted!

One of the electronics projects I had simmering away is now finished and in-service, my "vintage" Heathkit IM-103 AC Line Voltage Monitor.

I replaced the electrolytic capacitor, upgraded the rectifier to a 1N4007, and replaced two resistors. One of them was a 100 Ohm, 2 Watt resistor that was dissipating 1.8 Watts by design. More accurately, by design error, as running a part at 90% of it's maximum ratings is not a Real Good Thing to do. So I changed it to a 5 Watt rated resistor to keep things cooler inside the case. I also added an in-line "pigtail" fuse inside as a CYA protection. Using my calibrated Fluke meter and a big Variac transformer, I followed the calibration steps in the manual, and it's very accurate (better than 2%!) over the range of the meter. These were "Must Have" accessories for the well-equipped Ham Shack or repair shop in the 1960's, and I've always wanted one. Yes, the line voltage varies during the day. It's nominally 120 VAC, but I've seen it go as low as 117 VAC, and up to 121 VAC, so it's an interesting little doo-dad to hang on the wall.

And this unit has provenance!

It was owned by an Engineer who worked for Lockheed at Vandenberg Air Force Base. He was also a Ham, and I bought a few of his estate items from his Granddaughter via Big Internet Auction Site. I don't know if he used this at work, or snuck it through the Calibration Lab, but I was very careful not to disturb the stickers on the case:

The case was off when I calibrated it, and the two potentiometers were the type that can be adjusted from the back, so the stickers got through untouched.

Adds a nice touch to the workshop wall, I think.

Hope y'all have a good weekend. I'll be attempting to bake bread on Sunday. If you see smoke, I didn't do very well.....

Re-Earning My Stripes....

So what's a Radio Guy to do when propagation is crummy during the current Solar Minimum?

Work on his little model car, that's what. It's too cold to work on my "big" model car in the garage, a.k.k my "1-to-1 Scale" car.

The chassis is now basically complete, with the exception of the Timing and Scoring Transponder, which I have to buy from the track.

I've run it around in the basement a bit (it's FAST!), so now it's on to the body.

Since these little cars run bodies made of clear, vacuum-formed Lexan sheet, you have to paint them. And you paint them on the inside, with special paint. The plastic is only .040" thick, so it's quite flexible, and bends easily under impact, popping back to shape after you've hit something. To keep the paint looking good, and to preserve a high-gloss finish, you paint them on the inside, doing the darkest colors first, which is completely bass-ackwards from what I'm used to doing in both real cars, and other static display models I've built.

Took three hours and half a roll of masking tape before I got it "close enough" to paint. The last time I did this was 30some years ago, and it takes a while to get the skills back.

I went in the downstairs bathroom, turned the ventilator to "High", and sprayed the inside of the body with several light coats of paint, just enough to get uniform coverage in the stripe area.

And Holy Smokes, I'd forgotten how potent that type of paint is! It's very aromatic, and even the small amount I sprayed for the stripe was enough to really stink up the area. I wasn't planning on doing the white main color coat inside, and painting the stripe confirmed it! I'll have to wait until Friday when it's supposed to be 65* so I can finish the paint job out in the garage. The local "Marker's Space" is next door to the RC car track, but I don't think they have a spray booth or fume hood, so I'll have to come up with some way or place to do paint work during the winter months.

I made the mounting holes in the body before I did the masking and painting, and almost got them 100% correct. They're spot-on side-to-side, but I got them slightly off in the fore-to-aft direction, and had to oval them out a bit with my Dremel.

I'm not sure how much this will allow the body to shift fore-and-aft during use, or if it matters. I can block the back side of the hole with some adhesive-backed thin aluminum tape I have, or figure something else out if the body has too much movement. And I'm going to either have to get some different body mounting posts (the thing coming with holes in it coming through the body) or cut these down a LOT more!

So here it is loosely stuck on the car.

I'll clean any masking tape residue off the inside of the body tonight, and apply the window masks that came with the body, and wait until Friday when it should be warm enough to paint the body out in the garage. After that, I have to trim the excess plastic from the body, and then put my decals on.

Getting closer and closer to something like this.

And KRFC, one of two local stations, just played the "Peorgie Tirebiter" song.

I suspect the DJ is "Of A Certain Age".....

Gotta love Fort Collins!

Thank You All For Your Service

Not much more needs to be said.

God Bless our military, and our country.....

Small Wonders.....

And Fall Wonders, too!

I was able to snap a few pix of the trees here before all the leaves got blasted off by the cold and snow, and since Sarge and The Guys over at The Chant have been posting pretty pix, I thought I'd spring these on you.

Our Amur Maple tree in the front yard:

This variety of Maple doesn't get much bigger than ~25', but does extremely well here. It's a "Recommended" tree per The City of Fort Collins, and per the Wikipedia entry, "Produces copious amounts of seeds", which it does. When I was a wee lad growing up in Illinois we had maple trees. And so did the neighbors, of different varieties. The trees cross-pollinated, producing tons of seeds, and I grew several nice trees from seed. I've saved some of this years crop of seeds from this maple, and I'm going to try and get some started. We have precisely *one* place in the yard where a tree like this would be most welcome, so if I can get a seed to sprout, we'll plant it there. I doubt if I'll be around to see it get very big, but it'll be a tiny legacy left by me. A look at Google Maps of the house I grew up in shows a tree growing exactly where I planted one, so it might still be there, 60 years after I planted it.

And a tree that one of our neighbors has:

I'm no tree expert, but it looks an awful lot like the Birch tree we had back in Illinois. Seeing as we're in Colorado, it might be an Aspen, but the city strongly discourages Aspens as they propagate by runners, and can take over a large area very quickly. Reading about them brings to mind the problems I had with bamboo in the yard back in Kalifornia. Spent quite a bit of time, effort, and expense to terminate that stand with extreme prejudice!

Fall was quite pretty this year, and I even managed to get the front yard to come back, complete with about 30 sq ft of new seed that came up and took off like weeds. Half the back yard looks like the Mohave, minus the sand, and I'll have to bang away on that right early in the Spring.

I finished the new coax runs from the antennas to the entrance boxes I made, and got my FT-1000D back together again. Still has some problems, the most glaring being that it won't transmit on 40 Meters. I'm pretty sure the problem is in the Low Pass Filter Assembly, and fortunately that module is quite easy to service.

The Radio Controlled 4x4 truck is waiting for the yard to dry up so TLG and I can go out bashing with it again. I took it partially apart to check on some of the common wear points, and it's holding up quite well.

Since all we're going to do with the truck is bash it around the front and back yards, I don't want to spend money upgrading the little truck. I'm not racing it, but if/when something does break, I'll upgrade it with a better part, but that's it.

For the latent racer in me, I bought this:

It's a "3Racing Sakura Sport XI", four-wheel drive, 1/10th scale electric "Touring Car", and I'm building it to run in a "Spec Series". A "Spec Series" is where every racer is strictly limited on what equipment they can run, and it all has to be from an approved list. The chassis is pretty open, but the motor, speed controller, battery, and wheels/tires must be specific part numbers from specific manufacturers. The purpose of this series is to encourage slower speeds with older hardware, and make it more of a driver's match since the cars are so equal.

Since it's called the "Vintage Trans Am Series", all the bodies on the cars have to be 1960's/1970's pony cars, just like what raced Back In The Day.

I'm building a replica of the #8 Jerry Titus car, a 1970 Pontiac Trans Am:

There two bodies available, on from ProtoFORM:

Here's a nicely finished one:

And one from McAllister Racing:

I have one each of the bodies, and I'll probably go with the McAllister body for track-days, and do a very pretty job on the ProtoFORM body to be a display body.

See, I told you I wasn't going to modify the 4x4 truck!

Spooky Song.....

Don't know why, but I've always associated this song with Halloween. Maybe it's because I was in high-school, growing up fast, when all the things in the video were happening around me.

Spooky times, I guess.....

Birthday Party.....

I don't normally post stuff like this, but this picture came out pretty well. It's from the birthday party for the littlest one, in the center, flanked by our Little Guy, and her other cousin. All these little guys are two years old, and they'll be the same age until TLG's birthday in March.


I present you The Three Amigos, in full regalia for Halloween.

Winter Returns After a Short Break.....

Well, it was really nice here the last week. Temps were in the high 60's, nice and sunny, and quite beautiful.

So last night, this big Arctic High came roaring in from the North, and this morning it's 25* and lightly snowing. There was less on the ground than I expected this morning. Forecast is for 1"~3" accumulation today, with another 3"~5" tonight, then Monday should be a break in the snow until Tuesday/Tuesday night.

All the NWS says about Tuesday night is "Snow Could Be Heavy At Times".

Hmm....they don't know, either.

And we're in for some cold nights, with tonight forecast at 9*, Monday night at 10*, Tuesday night at 7*, and Wednesday night at 3*.

And I didn't get my wife's snow tires mounted while she was gone, so I'll either be chilling my tail getting them on this week, or paying to have it done.

I got most of the leaves blown out of the gravel and flower beds, but didn't rake and bag them, as that requires the two of us. We'll probably just have The Yard Guys do it when they do their early Winter clean-up, and drag all the lumber our neighbor's cottonwood tree dumped in our back yard. Some of the branches that dropped out of their tree are several inches in diameter, and although the tree looks OK to me, the tree guys who removed the cottonwood in our yard two years ago commented that it had "maybe five years left in it", so I expect we'll see them removing the tree in the next few years.

So keep warm, stay dry, and I'm on my way to a birthday party for one of The Little Guy's cousins.

A Little of This and That.....

Getting ready for some winter weather here. Currently at 45*F, overcast to (very) partly sunny, and it was raining a while ago. We're expecting rain turning to snow, with a low of around 23*F tonight. Looks like a good night to light off the fireplace and watch a movie.


-OR- Play with my radio stuff now that it's all back together.

I had my Yaesu FT-1000D apart to fix some issues it has, and install my Inrad Roofing Filter. The roofing filter installation went fine, but I wasn't able to fix one problem, and while I did fix another, it seems I've now introduced a new one.

Sigh.....

The one problem I fixed was a resetting/rebooting problem when I tuned from 6.5MHz to 7.5MHz. The radio would start cycling like the power switch was being turned on and off, and it was hard to get it out of that mode. I traced the problem to the Low Pass Filter board, so I cleaned and reseated all the connectors, along with loosening and tightening the screws that hold that board, and ground it, to the chassis.

Well, it receives just fine now on 40 Meters, but it won't transmit. It's possible it wouldn't transmit before, and the resetting problem was masking it, so it might be a wash on whether I fixed that problem or not.

The other problem is with a printed circuit board with a whole lotta push-button switches on it. Yaesu calls these assemblies "Switch Units", and they're a multiplexed group of switches that use fewer wires than if every switch had it's own pair of wires. The four switches that don't work share a common circuit path, so it should be easy to find and fix the problem.

That's IF I could get the board out!

This particular board is buried behind the front panel, and to get it out would take me a couple of days to disassemble the radio that far. I could do it if I built a fixture like a rotisserie to hold the chassis, but I'm not sure I want to do that. My days of wrestling 55 pound radios around on the bench are behind me, and even if I built a fixture, I'm not sure I want to dig that far into the radio.

One other thing I've finished up while the weather is cooperating has been to get new coax runs installed between my vertical and wire antennas and the entrance box I hung on the house. That also entailed making up some new jumpers for the box on the inside of the house to the coax switch, and coax switch to the radio and dummy load. I now have nice, matching jumpers that are the correct lengths, and the installation looks a lot neater. And there's no more cables running in the house via the small gap between the door and frame! I'm sure my wife will be happy about that.

As far as the radio goes, I'm pretty much in the same boat that SiG is in regarding his Icom Linear Amplifier. I can probably fix it, but it would take a significant effort to do so, and I'm not sure I want to.......

Crazy WINDY Here Today.....

Mother Nature's doing a bit of 'pruning.....

The backyard is covered with leaves and small branches, and most of the leaves are off our maple tree in the front and ash tree in the back.

NWS is predicting winds of 20~30MPH with gusts exceeding 55MPH. The high today will be around 50*F, dropping to '30-ish' overnight.

Glad I strapped the back gate together, but now I have to change the securing arrangements because the yard guys are coming tomorrow to mow and mulch whatever leaves and things are in the front and back yards.

Other than that, I got nothin', and I'm just gonna hang out in the basement today working on some projects.

Here's The Latest On The Ham Radio and Cal_Fire "Dispute"

Per my "Friends In High Places", here's the latest.

Uh-Oh...."Controlled Burn" Gets Out-Of-Control

And there's been a mandatory evacuation declared.

This is up in the Red Feather Lakes area, about 30 miles Northwest of here.

The full story is here, at the North Forty News website.

Prayers sent for those living up there.....
