I'm an idiot - learn from me!

Post by dougbilski » Mon Aug 25, 2008 12:15 pm

So... regarding that screw... And, since we're questioning sanity - you all should get a kick out of my stupidity...

I saw the screw in question in the back of my brand new LSS, and thought (like a complete idiot) that anything sticking out like that should really be screwed in ALL the way. Don't cringe...

So... I got out my electric drive and drove that sucker until it was all the way in! oops... The good news is that it didn't come sticking out the top of my amp. The bad news is that I called MB and found out that it really is just supposed to put tension on the chassis. They sent me a new screw since I stripped it in the process (I TOLD you I was an idiot).

Now, my question is whether or not to remove it, and make the repair to the top underside of the cabinet. I didn't realize there was foil there... I was thinking of taking it apart, using wood filler on the cabinet and reinstalling the new tension screw that they sent me. Or, I could just leave well enough alone. What do you think?

By the way, I do have an amp repair savvy friend who will help me with the repair. Clearly I can't be trusted with this kind of thing! :)

OK, "rib" me for all it's worth...

The screw in question.. just to clarrify... :)

on second pic, you can see the top of the screw has a grounding plate to make good contact with the shielding above.

How Hard?

Post by dougbilski » Sat Oct 11, 2008 9:42 am

How hard was it to remove the chassis? I'm thinking of trying to repair my "screw" up (pun intended) by replacing the screw and putting some wood putty into the underside of the cabinet where I undoubtedly chewed the heck out of it overtightening that screw!

What does that screw push against? Right into the wood of the cabinet or is there some kind of plate or something there?

dougbilski,

I just found that pic on the web when researching what the screw does, not had my chassis out. so Im not qualified to help, other than presume the top of the screw tightens against a foil sheet on underside of the cab top.

I've pulled my chassis out before to check when I thought my reverb was fubar.

It is not to hard just take your time and mind where you take your screws from....

My Lonestar does have a "rattle" especially when I play clean. Is this a screw I should look into tightening to reduce the rattle?

(OK, look when I play on the Drive channel everything in the house shakes so much I have no idea what the amp is doing.)

Thanks for clearing up the mystery on this screw for me.

Here's a shot of one sticking out of my Rocket 44:

Paul.
That is correct. The screw should just be snug. Do not over tighten. Note you need to loosen this screw before removing the chassis, from the cab.

Well I'll be damned... I just got an Electra Dyne combo and when I had the amp apart checking stuff out, I saw that long screw sticking out there. It looks really out of place. I couldn't figure out what the heck that's for and was thinking about calling Mesa just to ask. Then I saw this thread. LOL! Thanks for the info!

Does anyone have any info on this screw? My amp is missing it. I left a mesa with Mesa Tech support with no reply.

It looks like a #8 or #6 (32) coarse 3" screw. Can anyone confirm this.

Also, how much damage to the foil shielding would have to be done to warrant replacing it? there looks like there may be a few small tears (1/8") where someone over tightened the screw.

Ive read some people use screen, aluminum ducting sheets, or plain BBQ foil. Anyone have any experience with any of these materials?
