Motor Mount

[lv2plyguitar 172]

I need to make a motor mount for my o-200 but I don't want to pay exorbitant prices to a aircraft shop.  Are those mounts made of 4130?  I know that a Cessna 150 mount is very light.  Is there a special kind of welding needed or is tig okay.  Where do I get the tips that the bolts go through to mount to the fuselage like in the picture.  Below is a picture of a Merlin GT that I took pictures of with a C-85. 

 

Just need your help to get this mount started.

Perfect video.  Thanks  Do I just use 4130 for the tubing?  What are those tubes made of that the bolts go through.  Also is tig welding it together okay?

Tig welding 4130 is stronger and better looking, The bolt throughs are also 4130 just a thicker wall. Randy

what should the wall thickness be for the 4130 tubes.

For that engine you could use .049 and .058 4130. Here is mine I just finished it up tonight its for the 582 but gives you an idea. They don't take to long.
