FU1 and FU2!
Gremlin - 1/3/03 at 08:38 PM

I expect this has been asked before but I have had a quick search through and couldn’t find anything so here goes.

Am I being completely stupid or are tubes FU1 and 2 not mentioned in the RC second edition book other than in the plans? I’m a little unsure of how they are meant to be situated. Are they meant to be sat back from the edge of the chassis in line with the front upright ready to take the wishbones or is this too obvious?

Oh yes, the old FU's question. They are for mounting the suspension brackets. Do nothing but the lightest tack weld, or don't even bother with them until you get to mounting the suspension brackets - if you build goes anything like mine you'll move them about 20 times b4 you get them in the right spot!

You're correct about them being barely mentioned apart from a couple of pictures.

I put mine in this weekend (although I have a wider chassis so it was slightly different).

The key with FU1&2 is something that has been discussed on other forums but it also borne out by the CAD guys. If you look at one of the pictures (I forget the page number right now) of the front you can see that FU1&2 are somewhat inboard of the chassis. FU1&2 should actually be 0.22" inboard on a standard chassis.
You'll be cursing Ron C when you grind these out for the 5th time!

Has done the whole chassis in CAD and his site is well worth checking out.

Good Luck,

James

P.S. That sounds like I got mine wrong loads- I didn't have to grind mine out at all, but I did spend and hour setting upeach side before tack welding!
Thought I better let that be known!

Hi Gremlin check the message i sent to craig on more accurate suspension, get two peices of MDF 11 inches x 26 inches and mark out as on page 63 cw vertical centre lines so you can set to your base board , follow the procedure and you will see that fu1 and fu2 are set back from the top rails, this correct. cheers davef.

hey gremlin you'll soon discover when the've been moved a couple of times what FU stands for ( what are the f~~~~~ Useles bits of steel for anyway)
