Ray, that car was the subject of the "In the Beginning" thread but, you have to cover all 61 pages to see the build. There is a lot of other stuff in there (if you remember) besides the build itself. Very informative and interesting if you have the time to read it all!

What the hell? You post a comment, it shows an error, you go back and see that the post didn't "take", you do it again, same thing over and over. Then you close the browser, and go back only to find all your repeat posts took! I give up!

thread drift "Rant"
Yup, I think the "new and improved" is a POS. Post and it may or may not take....etc, etc....

This site is so hacked these days that I get AV warnings that links in this site are trying to get Java exploit crap on my machine. Prevoiusly it was a IE exploit.
From a fresh boot-up, post AV scan (which is loaded with the crap that does get through) only slotblog window open, and there it is again.



I know...it's only happening to me or I am imagining it.

[draggon]

Well, interesting.....I guess just because I never saw a one-winger doesnt mean I didnt exist! Can someone recommend where to get an inline motor bracket, and 1/16 piano wire? I cant seem to find the correct bracket, and my LHS closed so I have no nearby source for piano wire and brass rod.

Thanks again Jairus, for the link to RGeo's set up blocks. Im gonna have to wait till next year, they are a bit pricey.

Just in case anyone was wondering, 17T/#24 on a Mura blank with a Bugenis com and welded connections comes in at .081 ohms when measured at the com segments. Pretty silly eh?

Here is the "In the Beginning" thread. As Mike says... 'thread drift' went rampant with this one. http://www.slotforum...showtopic=17575

[One27ray]

Thanks Z for reminding us where the threads was at. YA! it was a long thread with a bunch of nonsense but, great info. And thanks J for the thread link- it was a long time ago..
Glenn, I never saw one myself ether. It was explained to me by Dave with a few drawings of the wing, I did see one on e-bay after the fact. From that I made the OneWinger you see today. Enough said on that subject.

[boxerdog]

First I got all fired up and built a motor...please excuse pics, early Mura C can, conservative arm, etc. Not as pretty as some I have seen, hopefully it runs.

[boxerdog]

Then I took a U-GO that I had and added some stuff, hopefully within the final rules. Now to combine all of the hardware with one of the bodies I got from Ray and go testing!

[Jairus]

Were those heat sinks available in 1970? Other than that I seen no problem with the rest including the chassis modifications. I wish you the best in testing!

[boxerdog]

I have no idea what was available in 1970 as Uncle Sam interfered with my slot racing career in 1968. I guess the interest I have in this time period stems from the fact I raced slot cars before and after this era but not during it. It's like discovering the missing link.

So...I am depending on the historians and those who did race then to keep us all informed. If the heat sinks are an issue let me know, I can remove them or butcher them up to look like a 1970 piece. More motors and chassis to follow, I hope.

[chief32s]

J...

Re Heat sinks. Am I correct in assuming that scratchbuilt heatsinks are permitted (in so much as I could have scratchbuilt a heatsink back in the day), but if a proprietary heat sink is used it must have been available >1970? So, should I desire to, I can cut up a piece of sheet aluminium and fashion it into a heatsink and that would be OK?

If the heat sinks are an issue let me know, I can remove them or butcher them up to look like a 1970 piece.

Surely if you have scratchbuilt them then they are the shape they are (and would have been back in the day also). Invention and experimentation are 'in the spirit' after all.

Al.

PS, doesn't the same apply for chassis design also?

[havlicek]

Not knowing what was available in 1970 Al, Jairus will be using hand cut heatsinks per his post on the previous page...so I'm guessing those are OK. My first choice motor for this is a Mabuchi can with a Champion "orange-picker" end bell and no heatsinks. If that winds up being stooooooooopid, I may have to go to "plan B".

Dave...the car and motor look great! Could you give more info about the arm and of course later on, the post-testing results!

[Gus Kelley]

Hey Guys! The thingies as you are trying to replicate were basicly a NorCal deal. Boxerdog is close on the chassis but has too much bracing on the outriggers, too heavy. Elephant ears were not around then either. I do believe we had thin aluminum heat-sinks under the brush hoods but they didn't extend outside the brush-hoods. Motors were "B"cans and machined "B" cans. Also in Sacto we worked with Mabuchi FT13Ds with the backs cut out and Mura mags epoxied in. Winds were 26 and 27 singles with some double winds thrown in, also one of my local heros played with triple and quad winds. Chassis were 3in wide with i/16 track clearance. Bodies were Choties and other amalgommations. At the end of the era we played with single and dual side-dams. the dual dams were eventually tied together. a rule because the cars would knock each other off when flattened and passing. Also in Sacto, we ran motor bearings starting in 65-66. A couple of guys had sourced aircraft instrument bearings Axle bearings were in use when I started racing in 63. Gus in Sacto

The current 'Watson Mule' is wearing a set of copper heat sinks that were first available in 1968. I got them from Randy (oldcertus) about 5 years ago and sent him a message a few days ago just to confirm this. I have no intention of breaking any rules either, thus the intent of my question about those sinks David.
There is no reason you cannot leave them on for testing. You might learn that they are not even required on your motor and Al is correct. You could modify them to look hand made... (nudge, nudge, wink wink)

As for heat sinks not being available... I noted a couple of Champion motors about 1968 that had tiny extended fins poking out on each side of the brush tube base plate. If not for additional cooling... there could be no other purpose.

Indeed, John is correct. My final entry will be wearing a set of hand made heat sinks as I am in the process of building a NEW lighter motor since that Mura B is just too heavy. But it will test as you saw it. (Just glued and trued up another set of JK SBR tires last night) Hoping to pop it in the mail to Buena Park Monday after Christmas. (I hate the P.O. this time of year)
Also, the motor is getting too hot on the bench. Searching for a set of Mura light brush springs in all my crap...

[boxerdog]

Gus,thanks for the info, I know the brass tubing braces on the outriggers are a little heavy...but I'd like to finish the race too. Not being a master fabricator, I did what I did. Plus, a vintage U-GO is far from straight and flat, I can assure you. The next one will be scratch.

John, the arm is a ProSlot 30t26. I have couple of others I want to try including a vintage engraved ProSlot but they are 23 or 23.5 wire winds and I don't think that will be needed. I could be wrong, but I suspect that the motors might overwhelm the chassis in many cases. Maybe even a nice Bob Green 27 would do the job, all of mine are long gone.

Chime in, this is all new stuff to me.

BTW:

I saw Dan "Doc" Dougherty at the track Saturday night and spoke to him at length about the Heatsinks / Elephant ears that he designed and tested. While running up in Ohio, Ken McDowell spotted them on Doc's cars and said " Can you make me a batch for resale". Doc had the pattern and said "sure". So in late 1968, early 1969 they were in production and and being sold retail.


Jairus, please stick with the 1970 cut off on the cans Cans and Endbells and now we know the heatsinks are period correct.

[One27ray]

I might have a pair of those elephant ear still around ?

i-ray

[Jairus]

Yeah, I got you Bob. The question is not whether they were available, that I know has been solved. The question is what styles were available and what was not. Pretty sure Parma didn't have their big rounded model until later in the 70's
So I am only say, when in doubt, hack it up some to look hand made.

[tonyp]

I have all the model car journals and as of July 1970 heat sinks had yet to appear on a pro car nor could I find an ad for any especially from Parma. I believe they came along later then 1970.

[Gator Bob]

That is what I thought originally but someone posted that "Doc" was one of the first ones to have them...so I asked him.

Never saw them in NJ back in 68/69 but they were there on the wall when I came back to play in 73.
