I never cut pins. One has to think ahead and think what would I do if I lose one? Run to the pits and then try to cut one the right size? That teeny little bit of weight is not going to do anything as bad as not having the right size one available. Oh yeah..and when you drop one and can't find it is also fun. LOL

I have about 100 pins already cut and bent in my box.

Agreed that the weight makes no difference on these cars. I do for the reason Tony joked about, and so I don't stick myself as well. LOL

Maybe I'll just Photoshop mine for now on. ;)

Always put the longer ones on the inside of the donut. I stick myself all the time, just too lazy to cut them.... What actually is good about leaving them long is when I practice I can leave them pretty loose in the tubes so it is easy to take the body off to make changes but they are long enough to not fall out of the tube.

Okay, guys, who was slated to tell Phil and then didn't?


Either I'm too dense to understand that Duff or you're being weird again. ;) What do you mean?


Yah. Short easy answer, I'm being weird again. Matter'fact, the default answer to The Duffy Conundrum. --But--what I meant was, "Here's Phil telling me [your issue here] makes me look like a Rookie, when I most basically AM a Rookie, Lo! these near-three years on. Soo, who didn't hip Phil to that thing, that the rest of you lot just nod and sigh about?"
("--Well, you know: DUFFY, right?..." --[nods and sighs all 'round]-- "....Oh. 'f course. DUFFY. We forgot....")

Well at least you did a good job Photoshopping the upper left pin. The others, not so much.


Just in case I'm being too Duffy again, the obvious P'shop job was a nod&wink to Phil. Copping a Plea, as it were. "--Huh? --wha' pins? where?..." (sweats, glances nervously around)...

Sticking myself with one enables me to stay alert at the races.

No really, all seriousness aside...

This is what I always hope will shake loose, in these threads: I'm an over-thoughtful builder NOT a knowledgeable one, and if I present these threads as some sort of journal, it might turn up just this sort of discussion; which some future noob may stumble on, and benefit by, as this noob is doing today.

Thanx all

A bump:
On a day when I've been:
1) Cleaning up from Thanksgiving
2) Finding there's actually not enough leftovers for a decent "leftover casserole" at tonight's table
3) Reconsidering my arthritic hands' decision to just drop out of playing Renaissance music and wait placidly for the first shovelful to hit my face
4) Responding to all the disparate rails against our Moderators

--I've been remiss in my Real Aim In Life, building slot cars.
Oh well.

Gonna finish off the OXCART "Gravy" stocker this weekend, & get it ready for HVR in December, I swear I am.

So, bump.

Bump two: a "Gravy" update...

Took the stock car to the RetroEast event at HVR, per post #36--but I'd had precisely NO prep time before that race day, and as luck would have it I was thrashing at the track in the morning. Sat right through the F1 and just managed to get the stocker out on the track fifteen minutes before tech--and the car was all over the place; popping out like a suicidal Whack-A-Mole. "Paint the front with LEAD, Duffy!!" screamed my Minions, and Lo!Behold, I did paint. Got worse. Finally pulled the car off the track before I could do any damage.

Finally got out for some shakedown this week (Yup, Duffy's the guy who puts the "Agnostic" in Diagnostic"...) after about two hours on the phone with TonyP (thx TP!), which helped line up my thinking, which I seem to need to do every now and then; probably on the same rotation as haircuts.
--I'm sorry, am I sidetracking too much? I'll try to control it.
Anyway: Tony was waxin' all eloquent about how our non-aero cars like F1 and Stocker can't rely on downforce the way we do in Can-Am and such; and he commented that a car will often "squat" on its outside-rear tire in a corner, esp. accelerating out of the corner, and that will lift the inner front tire, and guide--presto, front pops out. --Ahh, thought I.
(Now, remember: while YOU may know all this, and are now going "Wow, what an idiot Duffy is," I'm keeping this thread to document the learning curve of a skilled overthinker--a cautionary tale, an "Idiot's Guide" to slots. My discomfort may be instructive to some more sensible tyro later on. So, the narrative continues.)
--Ahh, tho't I--and so, this week I started taking the lead back off the front of the pans and transferring it, a bit at a time, to the rear. And Lo! the rear-er I got, the stuck-er the car drove.
I love it when a basic axiom proves out. Don't you?
I ultimately got about 5gr transferred to the tippy-back of the pans, and started getting a car that would slide out predictably in corners; something I could count on to let me learn what it wanted in my driving, at least. A good lesson learned hard, and over too many months.

Now--

Duffy47 OXCART GRAVY 10.jpg

--there's only so much I can lay on the back ends of the pans! And if that's working, how 'bout I add some mass even further to the rear?
So I ran a bar across the back of the guard, as you see here. If this works anywhere near well, I may start transferring lead from the back of the pans out here.
And watch the lap times.

Now...how do ya gonna hook up the Ox?

There is lots of room in the trunk of these big stock cars. Just a thought. ;)

DUFFY,
My guys at the track give me a hard time for running all my 90s stuff. :sarcastic_hand: I had an old long Mosseti that was good everywhere but going around the donut. It was lousy. This was with a Hawk 7 motor. Not with a G12. I put a long Vipor body and set it as far back as I could and picked up a tenth.. Added 2 laps to my total but the donut was still a problem. I took a hawk 7 and a light Koford G12 and weighed them. The Koford was 3.5 grams heavier. I added a .062 piece of brass at the far back behind the motor in the center , soldered to the chassis. That added 3 grams to the total........One HELL :shok: of a difference. Put 2 more grams of lead.....WOW.... Picked up another tenth and the donut was almost a full punch....So EASY to drive.....Should have left it alone but it was not flat anymore so I tried to fix it and snapped a primiter wing...... :dash2: AAAAAAAAAGGGGGGG..............So I bought a "beuf" short special.....and picked up another 2 tenths. :sun_bespectacled: .....
.Maybe this new stuff is.....slightly faster????? :victory:

OLPHRT
PHIL I. mmmmm ol'dog learnin some new tricks?? :D

Part of my problem is, I haven't had time to commit all the many little factors into a big, holistic "INSTINCT" like the Legends have had for so long they've forgotten they had it. Like, I remember tonyp talking a year or so ago about how he just makes chassis "like I used to, but I forget why"--and still, in our phone call the other day, he was giving anecdotal info and integrating it into his practice like he'd always talked like that. It's all in having the proper stimulus for the memory cells to kick in on.

And I'm trying to just get that platform into my brain.

Duffy: If that doesn't completely do the trick, try adding a rail of brass next to the main rails. Worked wonders on one of my previous builds that exhibited the same tendencies

Thanx VeeDub.

I'm encouraged that I am starting to understand the properties of single-rail chassis at long last, and am getting tempted to try dual and more--I know some're saying "about damn time, tyro!" but I'm not anybody but me, and me can't just go on faith that it's right, I have to understand--

--and yes, next shakedown session at the track, I am lugging The Big Box with soldering gear and some building stock, and trying out things like John's damper rails. Stay tuned.
