Topic: switching to a Round shaft and bearings for the RK DRUM (33 lines)

Rich nice job and good idea to carry the drum to the store for a proper fit
For those that may want to switch from a sq. spit rod to a round rod and 
rotate it in bearings here are a couple of ways to do that.
Inside dimensions of the square hollow tube running thru the RK Drum are.( 
across the flats .365 to .375 or 3/8" across the corners are .465 or 7/16" )
If it were not for the radius in the tubing and the sq. spit rod a 7/16" sq. 
rod wound have to be slightly nudged to get it to go thru.
For a round shaft you will need a 3/8" rod.
For even further strength a 1/2" rod with 2" of the end turned down to 3/8" 
and then welded in place, You would need to measure from each end of the 
drum with it centered in  your grill to determine the length of the 2 shafts 
+ the 2" that will go inside the tubing. A bit more work and certainly more 
costly, but stronger.
There is also one other way to convert the RK to a round shaft and run it in 
bearings.
Using a dremel with a stone or cut off disc, remove the weld holding the sq. 
tubing to the end plates. The holes in the end plates are .515 sq. a 1/2" 
shaft will then slide though the drum and if weld in place should do the job 
also.
FYI. I have been using  a 5/16" sq. spit rod since the completion  of the 
RK, and it seems to do OK but if you want your drum to run true and quiet 
the round shaft and bearings are the answer.
Rich nice job and good idea to carry the drum to the store for a proper fit.
