The strength in a box section in that application is in the top and bottom skins, the sides just link the skins, and contribute to the torsional stiffness of the member. In that application the torsional stiffness is dealt with by the cross members, so cutting holes in the side members presents no problem, within reason. Having said that I wouldn't be inclined to go beyond 50% cut outs, if I were to do it I'd cut 2" holes on 4" centres, so leaving 2" between holes. I won't do it on mine as I don't feel the gain is worth the time involved. I've taken long enough to set started as it is, I want to get my Morgan built as quickly as I can, within reason. I'm not setting myself a target, there are too many things that can get in the way, putting myself under a time constraint is likely to lead to mistakes, and result in it taking more time.

It would be interesting (I think) to calculate how much you would actually save. Not very much I suspect, so here we go.
.2" holes would be 3.14 sq inches (Pi r squared)
3 lbs /sq ft. 144 sq inches in a square ft,
Does that really mean 45 holes to save 3 lbs!
Worth the effort? Not to me. Above calculated on 16 gauge (1/16, or .0625) steel .

Interesting indeed Rhys, and since my frame rails are only 5' long definitely not worth the time involved, I've got little enough time to spare anyway.

Rhys this post would have been better served over on my "Racing Weight" thread rather than here!

So, with the new hub on the old axle your track is going to be a little narrower.



S'all for now!

If you look closely at the video you will see that the VKC hubs have a recess for the axle nut.
Steve says in his video that he has to space the VKC hip out to catch the treads on his old axle, thus moving the mounting surface out
making the rear track actually about 3/4" wider overall. Not Narrower!
On the Azuza hubs the mounting surface is flush
with where the treads end.

Slightly off topic, but still somewhat relevant. What I want to know is how does the guy do such accurate body work?

You don't say! Well, I guess Skye will just have to get in here and delete it.
