Hi! Looking for a legacy inlet temp sensor on 13 yr old Gene Cafe. It seems they've changed it and now you need new mother board and new sensor. Any ideas where I can find compatibile old one? Mark

Rotisserie Rod Material for RK Drum
EddieDove
The 6 lb RK Drum that has been sitting on the shelf for over a year is yearning to be put to use. Having had the 4 lb RK Drum in use for almost 2 years, I would like to improve some of the roller mounts and some other things including using a round bar for the rotisserie rod.

The local Ace Hardware only had cold-rolled steel, aluminum and some plated rods. Aluminum and the zinc-plated are out.

I picked up the 4 foot piece of 3/8 cold-rolled for a few dollars; I think I can hammer this through the square tube of the RK Drum. Is cold-rolled steel sufficient or does it need to be something else? I found 304 stainless steel rods (the drum is made from 304 stainless) online, but they are 6 feet long and $45 and up.

Most steels behave about the same way to heat so don't be worried, especially at roasting temps.

Are you trying to stiffen the square tube, or replace it with a solid rod? Don't try hammering. By the time you get it in a few inches it might bind up from the accumulated friction.

If putting the rod inside the tube shaft, file four flats on the rod until it goes in with just light hammer taps.

If replaceing the square tube with round rod, then fill the square holes in the drum with a round file until the rod fits, then secure with set screws, etc.

The square tube is 19 inches long and runs through the middle of the RK Drum, protruding about 1/2 inch on either end. This is where the usual rotisserie rod runs through on the 4 lb RK Drum, which is a square rod. It does not fit very tight and can make noise. Also, collars and jaw coupling don't exactly fit right on the square rod, which makes things a bit eccentric. Thus, the reason for wanting to use round rod.

The inside of the square tube measures 3/8" (with a tape measure) and the round rod is 3/8" outside diameter. I want that rod to go through that square tube.

The goal is to make this as smooth and quiet as possible.

Then go with this option:

If putting the rod inside the tube shaft, file four flats on the rod until it goes in with just light hammer taps.

Then, once it is in, "stake" the rod in place. This will remove the last bit of movement. That is, take a center punch and punch the ends of the square tube on all four sides so it pinches onto the rod.

Dan,

Thank you so much for a simple and practical solution!!!!! s:2s:1s:2s:1s:2

I just happen to have an air file that I got for Christmas last year, so making the flat sides will be a snap.

Using my cordless drill and a flat file, I was just rounding over one end (so it doesn't dig in) and putting a light polish on the round bar with 180 grit emery cloth.

I didn't even think about pinching the ends like that.

This is PERFECT SOLUTION!!! Thank you so much! s:2s:1s:2s:1s:2s:1s:2
