I spent about an hour tonight softening up and removing paint from the stamp pad (PO rebuilt the motor, didn't bother to tape it off during paint) this evening with lacquer thinner and Q-tips, since I didn't want to risk doing anything to the broach marks. Is this a thorough enough job? Thanks!

Re: What I see in your photo...
Beautiful broach marks! I'd keep doing what you were doing and remove the rest of the paint just to make it look pretty. It doesnt look like you're hurting anything. I think it will look better when the orange is out of the characters. Take your time, it's turning out great.

Nice photo! Nice pad!
I would drop a couple of drops lacquer thinner on your pad and let it sit. Then I would take an old tooth brush and see if you can get that paint out of the crevices. The lacquer may attach the plastic bristles in the brush but I would try that as the strongest form of scrubbing device.

I agree with Dennis
Good enough. Stamp pad was originally painted and wiped leaving an appearance similar to what you have. They didn't clean it with a toothbrush at the factory. If you want concours, keep cleaning, otherwise your effort appears to me to be "No better, no worse, no different". Regards, Bernie Myers- Top

Re: I agree with Dennis
Do you mean that the pad was actually painted and then cleaned at the time the block was painted??- Top

Yes, that's my understanding. I'm sure someone will correct me if I'm wrong.- Top

Re: Judging Question: Stamp pad paint removal (62-
Since Dennis has been the National Judging Chairman in the past, as well as 61-62 judging chairman--I think that his advice can be taken to heart.
In addition, since I've been heading up 61-62 national judging teams off and on since the early 80's, I think I have a bit of stature in the hobby. If I had a judge take issue with that pad, he wouldn't be one of my judges for very long.
There still is a lack of consensus on what they did in 62. Some say the pad was covered when the engine was painted (I don't believe that). Others say that it was wiped off after paint, as Bernie said. I'm not sure I buy that.
Others have said that it was painted along with the block, and then when the VIN was stamped at St. Louis, that broke the paint in that area, so that the assembly date code would be painted, while the Vin code is stamped in on top of, and disturbing, the paint. I'm not sure about that.
What I do know is that the NCRS now expects that the pad is paint free and rust-free for judging--you're just about there.- Top

Re: I agree with Dennis
John--
I'm hoping you were a part of that process--over the years I've received different inputs from knowledgeable people. I'm trying to get this from someone who worked in that part of the plant and was there in 1962. So far, no luck. Can you point me to someone with first-hand knowledge, either at the engine plant in Michigan, or at St. Louis? I understand that they had different procedures at different times--I'm really trying to pin down 61 and 62.
Thanks,
Mike- Top

I know it was done that way in the mid-60's, don't know if it was done the same way in '61-'62 or not. However, the pad had to be easily readable after the paint booth so the engine could be conveyor-routed to the correct location on the shipping dock for racking and loading in a rail car - they hit that system one every twelve seconds. Here's a photo of the '55 passenger car engines being plucked off the delivery conveyor at the shipping dock where they were set in the shipping racks.

I am sure it would but do you want to take a chance at damaging the broach marks? I would stick with nylon or other soft products. I used to use a green nylon pot scrubber on my LT1 pad to keep it rust free until I used that same pad to clean other metal pieces and noticed that it really scratched the pan I was working on.

The definitive answer ...
from three knowledgable authorities; Mike, John and Dennis. Yes, no and maybe; and worthwhile opinions from others. As your question relates to judging, there is no way to deduct a couple of points for some perceived imperfection; the stamp pad is judged as correct or incorrect. You either get all the points or none of the points; there is no in-between. In your case, based on your photo (good one too I might add), I don't see how anyone could justify a deduction. PERSONALLY, If I saw your pad completely cleaned and devoid of paint, I would draw a line through the score box and continue (no deduction). If I saw it as photographed, I'd do the same thing except probably add a complimentary note to the side. Bernie Myers- Top
