question: how do i fill unwanted holes in a model a frame???

[atch]

pretty much what the title says. what's the best way to fill in all those holes i don't want in a model a frame?

i finally decided that a frame made from a new piece of rectangular steel wouldn't be or look as cool as one made from a model a frame. what with the tapers and corner radii etc. so i bought the frame and now want to fill in a BUNCH of those holes.

i know this topic has been discussed in general; i.e., use filler plugs, put flat copper behind the hole and mig it in, etc. i know several ways to accomplish this. what i'd like to know is if migging a hole in now will cause problems down the road? or will migging in a plug cause any problems in the future? mostly, what happens later on, depending on which way i fill them?

oh, yeah, i did a search and didn't find what i was looking for.

i would use a brass block not copper, anyhow, just mig them shut ,nothing is gonna happen ,dont weld the cross members
atthe rivet mounts, old chassis were designed for flex, so at the least box the frame up frontif you are gonna run a powerfull motor,other than that ,

guess i shoulda said that i'm gonna box the entire frame and that this car will have a 401 nailhead with a manual 4-sp & 9 incher.

Atch,

I mig'd mine shut BEFORE boxing the frame. Again use Brass backing on the hole, clamp it to the back side and mig fill weld away. There will be lots of grinding but in the end it will be worth it.

as with welding any frame,

try not to concentrate too much heat in any one area

as the metal cools it will pull towards the weld area

and warp your frame.

shouldn't be a problem with the stock bolt and rivet holes.

but with large round holes,

make the plug of the same thickness and weld one quarter way around,

then weld the opposite side of the circle, and let it cool before you weld the rest.

if you weld all the way around full circle as it cools the patch will shrink and can crack at the weld.

More labor intensive, maybe, but it works, Saw off thin plugs from the appropriate OD round bar stock (chamfer the outside edge first). Then you can tack them in, jump around for no warpage and have less grinding.

Sorry, I didn't read all the way down. You're exactly right.

before you box the frame make sure you weld nuts for any parts that get bolted to the frame. also get some good weld threw prime for the aresa that you cant get paint to later.
