Default Ideas on freeing up frozen brake drum on trailer

Picked up this little heavy duty trailer on CL for $50. Plan is to make a little dump trailer for my tractor. However, one drum is frozen, looking for some ideas on getting it free again.

I've tried some penetrating fluid (dont care about preserving the brake pads) between backing plate and drum and a pipe wrench with cheater on the raised portions on the drum face but I was stressing the pipe wrench too much. Thinking about making a plate to bolt on the drum with a welded stub or arm to attach the cheater pipe to.

Looking for any tricks you guys have.

I would wallop it with a 5 lb sledge, and rotate 90 deg, do it again until I had gone full circle. In your case you can't turn it, so the thing to do is to drill the backplate where the shoe meets the drum so the contact area is exposed. Then drive a screwdriver or small chisel between the shoe and the drum. This will part them.

Or, undo or cut the bolts holding the back plate to the axle, usually 4 of them, and remove the axle nut and bearing and pull the whole thing off the spindle. A new drum and backplate with shoes and magnet is not that expensive from e-trailer dot com.
$90 for a set of 2 backplates.
