My brain don't see it, Ray; sorry. I guess I'll have to hold it in my hands to see better. I've seen a "z-bend" tool in the RC area of a local hobby shop... is that the tool you referred to?

Hey RL, I've got a couple of those benders if you'd like to experiment with them. If you want, I'll bring'em down to All Scale and you can borrow them for a bit and see what you can come up with.

Finally got around to finishing up an idea I had. It's now a prototype/pre-production model. Going to test it as soon as the home situation allows me the time. Once I (or someone else I'll get to test it) is happy with it, I'll post in the Parts Counter section and 'pay the man'!
Pretty straight forward. 4" x 1". Front end parts are .040", 1/2 - 3/4 hard brass. .063" rails. Motor bracket is a stock REH---when I saw the P/S line of motors aligned with the brackets holes, I didn't do anything further, so if you're using a Falcon...
What I particularly like, if I do say so myself (and I do...) is the alternative pan stops that eliminates a cross piece et al.
Got enough pieces/parts being readied to do 20-24 run although at least 3 are spoken for/assigned (You looking, Matt! LOL).
I'll post pricing info when it goes down to the Parts section. Trying to get a feel for it.

Hmmmm?
Sorry don't understand how a P/S motor will bolt into this bracket and a F7 motor won't as the sideways bolts patterns are the same dimensions.
From my experience is these REH brackets need extra drilled holes.

Those horizontal holes in the REH brackets fit the small Hemi cans like what Pactra, Testor, & others used.

Brian, you can use the vertical holes, though you have to be careful not to strip them.

Cap is correct. They are not tapped in the P/S motors. I suggest the use of a Retro Specific Bracket for production use.............Drilling those holes ACCURATELY is not easy after the chassis is built. A bit easier when working on just the bracket. IMO of course

Oh! Ok, thanks for that bit of info Cap
Sorry, Jim
Great looking chassis!
Still agree with Ray and use a 'retro specific' motor bracket.

A easier solution is to just slot from the horizontal screw hole to can bearing hole on the bracket. The motor cant really move once tight....

Couldn't you just cut the back off of an old Falcon motor and use it for a drill guide?

I had actually considered making a drilling jig like Rick said but, instead, was going to do what Cap suggested.
As for flexing, the photo doesn't show the .063" brass strip soldered to the base of the bracket from side to side. That 'face' ain't going anywhere.
Too bad I can't go to MMW this Saturday.
Or anywhere for that matter.

For the rest of us builders here as well--I've been paying a lot more attention to the motor/ bracket face lately; stoning the bracket flat before jigging-up, torquing the motor down under power and listening for changes in RPM that indicate a bind, & especially using 2mm machine screws (thanks Jay Kisling for that heads-up!).
While slotting or routing-out of mismatched holes is good in these applications, we still should pay close attention to all those slops & non-slops in this area.
