Just got my E2 on the Fastback.

I have some concerns that I want to share.

The sled is hitting the fangs really hard and has started to flatten a section on the back side of the sled. The wear is not symetrical either. This seems to be only affecting the side that the pump arm goes into. There is also considerable wear under the sled on the body affecting same side as the pump arm. Almost all of this wear has been since I put the E2, Palmer Quick Ram, and Palmer Micro Rock on.

I got it back from Palmers yesterday and was using the training mode for a few hours and that is when just about %80 of this damage has occured.

I have checked that the pump arm is in all the way, and it is. The sled is hitting the front of its travel path as well, but not as hard. I am not so worried about all the annodizing coming off, but I am worried about the damage to the sled and fangs.

Any and all suggestions are welcome and very appreciated.

PS. This thing rocks. The cycle time is insanely fast.

both the back and front, the ram is allowing too much travel. The only thing I can think of is put a different ram in there. You could turn down the pressure of the LPR, maybe, but the range of travel sounds like it is just too great. That isn't going to change. Reducing the pressure might reduc ethe force of each time it strikes, but...

I would be changin' that ram out. Especially seeing how difficult it has been for me to get a Fastback body (mission not accomplished, yet).

what you need to do is adjust both where the ram screws into the pump rod and where the ram screws into the pump rod. if the sled is going too far forward, screw the ram in towards the body. Then, fine tune it by screwing the ram and pump arm closer together until the sled no longer goes back as far.

This is an annoyance in the fastback design with the fangs. Most rams have a 1" throw. The clearance where the sled can travel I measured on mine was about ~2.615". The sled itself measured in at ~1.612". That leaves about ~1.003" for the sled to move back and forth without slamming the body. That's a tight tolerance and you can see how critical timing the backblock movement is. It's not correct to just randomly screw in the pump arm to the ram. It needs to be very fine tuned to not slap around.

-yochi.

I've considered getting a FB withOUT the silly fangs. I don't like the look myself and have always been wondering if they would ever make contact.

That, and I seem to remember asking why there were no ball bearings supporting the sled's travel.....I was told it didn't wear enough to matter grin
