I have had to polish the shaft with some .059 ball bearings since they seem to be exactly .059 and not .060 so you can install them on an .059 shaft. I am sure there are some bearings out there for the .063, (measured on the serrated part of the rear axle shaft), .061 on the smooth part. You would need a center of .064-.065 so that you can get the bearing on the shaft. This might make for too much slop when they are on the smooth part of the shaft. Measured 2 new pancake armatures and they were .062 so they are slightly different. I will take a look at Bohl bearings and see what they have. Let you know if they have anything.

I decided i didnt really care for the look of the first motor... so i robbed a motor from a funny car. and then i took both motors apart... And 3 hours later... i still dont have linkages, fuel lines or plug wires done yet, but im tired of working on it for now. And the glue needs to set. Heres where patience comes in...

My point exactly peter, remove friction. I believe you remove more with bearings than you do with bushings unless like you said you can get it to "float" typically to do so you need oil/lubricant. Ive noticed on most of the chassis ive pulled apart the brushes are coated in grease, cleaned them off and armature and ran like a top. If i can get a flanged sealed bearing here ill A. Eliminate oil contamination to bushings and B. Reduce friction. As with anything theres always a way, i just need to find it. Floating the shaft is something I try to do with both bushings & bearings. Problem with chassis floor is space OD of bearing would have to be like .010 over ID. Or it will not fit between brush pockets. Pockets could be moved out or away from shaft by using brush cups. I'm not sure how that would affect operation. Brushes would travel over a greater distance on each segment of comm. Intresting............hmmmm. Typically routine maintenance includes cleaning brushes & comm plates. Dust from brushes is constant. Comm plates need to be checked so build up from brushes between plates does not short them out. Much of this is due to type of brush used. The softer.they are the faster.they turn to dust. Though at times runs of brushes from any mfg may be "off". Resulting in sub standard brushes. One thing about sealed bearings....... seen this countless times. A sealed bearing will achieve a higher rpm than a bearing that is not sealed. HOWEVER , a bearing that is not sealed will reach its max faster than a sealed bearing. In each case with same loads applied. I suppose this might just be my opinion. But it was learned.the hard way, pavement hard ! Peter .........

Bahaha, Hey... sometimes to get it the way you want you gotta use the Cleaver lol. I cut the hole in the hood for the first motor to sit in and it just looked bland... im my head i heard whomp,whomp...whooommmmp. i dont have alot of engine stuff and dont really care for Ashley Force so i donated it to the Flat Car Fund. For those of you concerned... she will be OK, her dad can buy her a new one... LOL

You all put a lot of small details into those motors. Hard for me to see, without a magnifier anyway. Peter sent one of his roadsters to the January race with a lot of engine detail, plug wires, etc. looked real good, like the one in his profile picture.

Yea but Peter cheats... hes like Yoda, he uses the force to put his plug wires on. LOL!

Like the Yoda reference. A Jedi master in action. Disney is taking over Star Wars, most likely they will ruin it. Hope I am wrong.

Flat, I've seen you are shaping tires. Trueing them also I hope.
Not sure if you've thought of this but stock.wheels often need trueing also. Without checking this first trueing tires is compensating for it and never really gets right.

Very observant peter, i havnt really done either but when rounding them the center didnt match with the sides so i just worked the disc across enough to smooth the difference, ive been looking into building a rim/tire machine tho...

I usually use a dremel instead of going in the garage for drill press.
Getting tires round is important and it starts at the hub. Saw mention of high speed. Nooooooot for silicone tires ! They will expand & fly !
If you can follow the ricochet sound you have a chance of finding tire. Or in three months you'll be saying........ here it is.

Lol well i meant high speed on a drill which isnt near as fast as a dremel. When i build the wheel and tire sander ill have to post pictures.
I got fuel lines, distributor and plug wires on the motor,but i havnt taken any pictures.

Looking forward to the pics........... saw a few top fuel cars in pics, motors are waiting for you :-) .......... Peter

I know, ive got a plate full though at the moment, Cuda build, i ordered 2 66' Chevy Fleetsides from HairyCanary one will be a more stock build... the other will be a rusted promod, And last but not least ive got a couple of projects being sent in from a couple of you guys. When that stuff gets here i will get it done and sent back, if im waiting for stuff to dry ill work back and forth, thats the good thing of having a couple to do, while you wait you can work on something different. Ive got alot of ideas, thoughts on building a track but i need to take my time and not get overwhelmed and keep it fun, cause if it gets to where you arnt having fun... you need a break.

Motors done, grille is also done, ill be working on body posts and getting this chassis mounted. This body is Very narrow so ive had to modify the standard 4G chassis to get it to fit. Rims will be much more narrow than the 66' chassis and as close as it was to riding the rails that means this chassis will have very narrow tires, .05 by just a guess. Thats all i have for now
