Thompson Hardtop Rocket Launcher Attachment

[tlavan]

Hi All:

 

I have a pair of rocket launchers to mount on my Thompson hardtop. They have a 1/4" aluminum base and 7 rod holders welded to the bases. At any rate, how did you guys with a Thompson attach them to your hardtop? The top is like 6 inches thick. Did you drill the entire way through the top using nuts and bolts? Is there wood inside the top which would allow wood screws to be used? They came with 1" nuts and bolts which must have come off of a very thin top. 

 

THANKS for your help!

Definitely thru-bolt it. Silicone in the holes, and big washers on the inside behind the nuts.

We used a hole saw in the corners of the rear of the top. Then reached inside the top to put the nuts on the bolts. Then got some covers from west marine to cover the access holes.

I mounted a Cisco 10 rod rocket launcher on my Penn Yan hardtop using 1" screws and 3M 5500 under the base.

 

Solid as a rock so far and we even use the rod holders as grab handles when we climb up on the gunnels to go up front.

Top is hollow. I did similar as mudflat. my rocket launcher is removable and attached to two trax tech six inch tracks.

Thanks for all the replies!

Just remember that if you bed it down with 5500 you won't be taking it back off without doing some fiberglass repair work!

Mud.....got it. I need to take it off to reuse my shrink wrap cover anyhow so liked the idea of trax to slide it in and out of. Appreciate your time replying! Hope your season is a good one!
