Had no resolutions, so maybe a revolution or two...

 

But did resolve to try this and see what happens.

 

 

This big block stroker too, standard 36D arm at the bottom.

Hi Geary!

 

I'm looking forward to viewing the "evolution" of this "big block stroker motor!"

Big block stroker begins...

 

The original arm was wound with 35 turns of .45mmm diameter wire, around 25 AWG, so we need to go a bit stouter on the wind. Re-shafted arm with M2 drill blank and added big comm for a big block.

Hi Geary,

 

That looks exceptional!

 

The middle photo - - -  I've never seen a bracket plate like that mounted on a slot car motor before - may I ask what is the purpose of it please?

 

Thanks Geary!

[Geary Carrier]

Hi Ernie,

 

The bracket is for holding the large oilite and dissipating a bit of heat.

Hi Geary,

 

Thank you for prompt reply!

I appreciate the info - and so "trick" looking!

 

Thanks again Geary.

Comm and spacers loctited in place, just have to decide on 32 or 23 AWG, or somewhere in between.

 

Stack is .712 long so this arm is pretty well jammed into this motor with not much room for wire clearance on the can end, we will see what transpires...

Yes - yes!

 

Let us see what transpires - and I know it will be an awesome build!

 

Whatever wire gauge you select Geary, I know it will run well!

 

More pix please - LOL

Thanks Ernie,

 

We'll know pretty soon how mild this motor will be...

Hi Geary.  I've shortened those stacks many times by carefully removing the end lam using an X-acto blade pressed between the crowns on all three sides to break the powder coat without deforming the lam too much (*and it can be flattened afterwards anyway).  Afterwards, you can do the same with less car to remove as many lams as you wish, and them reinstall the end lam using CA glue or epoxy and some clips to hold it while it all cures.

The long stack will of course work, but the powder coating is very thick on these arms, and while the stuff is generally brittle, it is pretty durable.  If you do chip it a little, some JB Weld applied with a toothpick makes for an easy repair before winding.  The long and heavy stack (*these lams have a LOT of iron) will make for a slower "wind-up", but the arm should run well anyway.  I figure you may already know this, but wanted to offer this just in case! 

[Geary Carrier]

Thanks John,

 

I left this stack long as a requisite for the stroker part of the motor. As you say it will wind up slow with a decent amount of torque, which might work as a stump puller.

 

Just wanted to see if I could fit this much arm in a 36D, sort of like a 68 Olds 442...

Gotcha.  Stuffing as much arm as possible into a motor has always been a personal fave also!    Carry on!

[Geary Carrier]

A 53 wind for the stroker seemed appropriate.

 

Required a glove for the right hand as the pain/tension ratio was a tad high without one. 23 wire requires a bunch of tension to lay reasonably flat and straight...

 

[havlicek]

That'll dim the lights in Fresno. 

PS...you do really nice work!

[Geary Carrier]

Thank you John...

[olescratch]

  A 53 wind is saying 25 of 23 correct or not?  Let me know when you're gonna test that, I'd like to unplug all the electronics in my room to prevent any power drain here in Ohio!  That arm looks real nice, good job!

[old & gray]

That is one beautiful armature.

 

What kind of car are you going to run it in?

And where are you going to run it?

It is 15 turns of 23.

 

Not to worry I'll go slow...

I'm not sure what I'm going to do with it yet...

[SpeedyNH]

this all makes me wonder if any "modern" chassis have been built for a 36D. I don't think that any of my vintage stuff would allow an excellent motor like this one to be used properly.

[boxerdog]

The best one I've seen or raced was the old American Line brass/wire chassis. That would be an interesting hack on a retro anglewinder maybe???

[Bill from NH]

Some NOS 36D chassis have been showing up lately on eBay. They seem to have wire center-sections rather than the stamped Riggen that was available in both brass & steel.

[SlotStox#53]

Very nice work! Don't recall you mentioning what magnets you're going to try and stuff this stroker arm into?

One brutal big block 36 in the making

[Tom Katsanis]

I have two drag chassis's built with John H prepared 36d motors I only ran them for the first time last friday night (besides running in the big 36d class in the dc punk rods & rails proxy race which my mustang won).

So the best I got out of them so far is about a .95 out of both cars just under 60mph there are still a few things I can do to them to make them go faster & it was the first night the track was open so I hope to go faster still.

The Mustang has dual segment neos with a 63 wind & the Dragnoda P thingie drag car has arcos & a 94 wind.

Very nice looking cars Tom, to be sure...

[SpeedyNH]

I find it odd no sidewinders.
