The 85 with the narrow arm & button soldered brushes are the older model.

If the newer one is anything like the RAM 850 I've had to file down the heads of the motor screws for the wider brush arms to clear them.

Was even thinking of slightly counter sinking the screw holes in the rail sides to lower them hence missing the brush arm.

 Hi Joe,

 

I have some DC-65 parts for sale. No brushes or springs and plungers though. I have new old stock in the package:

 

6 volt arm

Both style side plates with bearings and brush holder plate

 

And one loose motor missing the arm and brushes/springs

 

I love your eBay find. Neat car.

 

Good luck with your project,

 

Rick

 

Rick, are these goodies all sold ?

 

I have two complete here but one is the nice motor you donated to Tony P. for a recreate on my build list.

Ahhh.. the early ones.

They offer a bit more clearance .. correct?

Thanks Paul.

 Sorry, they were sold Bob. EJ's still lists 6V 65 arms in their catalog though.........

Hi Bob,

 

I did take lotsa pics as I was putting this drag car together. 

 

It took 3 mods to get enough room as to not short out on the 2-56 screw heads. I'm using the standard 85A brushes.

 

1) I filed away about .020-.025" of the brush arm until it was getting pretty close to the rectangular plunger hole.

 

2) I picked up some 2-56 black oxide screws that have a head that's about half the thickness of the Pittman screws. 

 

3) The brush arms then cleared the screw heads, but only by about .006", too close for comfort, so I counter bored the slots in the frame another .007".

 

The round headed brushes on the narrow arms would be from a DC85, the "A's" predecessor. Those arms take pitchforks like the baby padlock 65A and would need to mount in a fiber board hence you would need the 85's end frame.

More clearance , yes , but the arms are longer and fit in a fiber panel Like the dc65 instead of resting on the round posts.

Thought they'd fit but the extra length puts the brush past the comm!

I was thinking of trying a 3 pole in a 65x for the 'unlimited class'.

 Awesome Bob ... thanks that should help a lot. The 'pitch forks' :diablo: are 'fiddly' and I haven't seen the non-A fiber board yet.

Ahhh ... too long to use the pre- A brushes on an A.

Got it ... I'll stop hunting for those. :dash2:  :laugh2:

Here are a couple of shots of an old DC85's brush set up.

 

I find two things odd about these old padlocks.

 

I own 3 of these motors and 2 of them have end plates that are full of cracks, as though the metal is shrinking :shok:

 

The other odd thing is the pitchforks. One is fiber and the other is metal!

WOW,

Krusty 'endbell' syndrome. (KES) or The incredibly rare shrinking metal disease.

 

Geez, those look like they have LESS room for the rails.

 

Thank for post the pics...

EJ's has way more stuff than is on his web site. He has a print catalog too. You'd need to call him to see if he still has the 65 arms listed in his latest print catalog.

Looks about right Bob, just minus 1 rail.. hasn't gone together right at all and will be attempting to now concentrate on the unlimited entry instead :good:

Thanks for mentioning EJ's Rick , reminds me to order his catalog.

I hear ya Paul.

One on the jig .. a crazy wire and brass rail which is/was the intended platform for both a 65x-6 and a 84-6 turns out to have a design flaw and now I'm looking for solution or work around for about two weeks.

 

The RGeo has moved to the front burner for now. I saw Don S. had a K&B with a Kemtron type that could be a great combo. tonight I'll see if  I can fit it in the Rick's Rails kit.

 

I have not 'cracked the seal' yet on the NOS K&B from Electric Dreams.  You know ... those two guys .. one on each shoulder.  

Open it   :crazy:...  Save it :)     

Open it damn it :diablo: ...  Don't be a fool, it's only NOS once  :D 

:dash2:  :laugh2:

I just went into my old frame motor box and found a couple incomplete DC65s: one almost complete but the brush holder is broken and no brushes and the other with just the back plate, lams and an arm, but no front (brush-holder) plate... a couple arms too (don't know if 6 or 12 volts) if anybody needs this stuff to play around with, let me know. 

 

Only problem is shipping: France changed its postal rates this year and there's no more uninsured small box rate! Minimum is about $25 for any kind of box, but I think I can get these into a padded letter, and then it goes for a normal letter rate.

The Kemtron motors fit the RGeo rails, that's what's in the competing rail :good:

The spacing of the motor screws are different to the Pittman & RAM so some filing of holes on the rail kit is needed.

Plus a tiny bit of cutting on the rail sides & axle hanger to clear the comm & brush gear of the Kemtron (at least that is what I had to do using their Mustang motor, which is virtually the same as the X503)

As for the open or not open dilemma, I would be in the same argument :laugh2: if I'd gotten the other K&B or the Russkit Eliminator they had.

Don, I think Bob could be on the look out for the mini Pittman parts :good:

Brushes hitting the screws was a common design flaw on these factory made rails. A few I have picked up over the years have had electrical or some other tape there. Not pretty but it allowed the setup out of the box to work. Maybe a guard made out of very thin acetate would work. It could be attached to the screws with clear epoxy.

 

Bob, my K&B rail is definitely in but as is it's just under 8". I would have to lengthen it to be in the rail class which I may do by adding a body of some sort. I will advise when I decide.

Very cool Don, I would like to get a set-up even if the insulator is broken because a 36D brush holder modification was/is part of the plan.

 

I would not be able to do a major custom build in time for this proxy but .... next years 'unlimited neo' class is what it would be for.

So ... there is absolutely no hurry. If you break it down to 'loose lams' it should fit a padded envelope.

I insist on paying or trading.

 

 

The Kemtron motors fit the RGeo rails, that's what's in the competing rail :good:

 Thanks for the 'first hand' tips on mounting the Kemtron !

Brushes hitting the screws was a common design flaw on these factory made rails. A few I have picked up over the years have had electrical or some other tape there. Not pretty but it allowed the setup out of the box to work. Maybe a guard made out of very thin acetate would work. It could be attached to the screws with clear epoxy.

 

Bob, my K&B rail is definitely in but as is it's just under 8". I would have to lengthen it to be in the rail class which I may do by adding a body of some sort. I will advise when I decide.

 

Good call on the insulating guard, I have some thin Mica insulators as used with TO-3 package transistor. That could work well...maybe. LOL

 

On the Rail - the spec is 'overall' so a body, longer drop arm or flag, or a faux bumper would be fine.

 

K&B and others producing chassis kits for other manufactures motors seems a little weird but there must have been a fairly strong market for drag chassis kits.

36D brush holder on a dc65 hey Bob?

Great minds think alike! That's why I asked for another motor as I'd had exactly the same thoughts!!

Unlimited neo equipped 65 with Mura brush etc :D

Not sure I can imagine how you guys are going to fit a 36D brush holder on a DC65.... great minds, or cracked minds? 

 

Bob, you want just the complete setup, or the whole shebang (ie, the partial setup as well)? I'm sure we can work out some kind of trade...
