RMS Corvair + The "HindWinder"

[HomeRacingWorld]

I took the advice and added a second brace.



Btaylor said if I didn't break it all down and redo it at least 2 more times, I wasn't taking it seriously. :)



I did not have that small paino wire so used brass. It will have to do.

Thanks all for the assist.

Thank you for the bracket link Harry - and the brace addition looks NICE!!

I've decided I won't bother making one ;)

Thanks for the link Harry, just placed my first order with PCH.

Yes Sir, that looks pretty nice. Now if we could just do something about that sloppy soldering job, you would be in business. :lol:
I can see a whole bunch of these in your future!

All kidding aside, that looks fantastic. I really like the way you have done this set up. I hope to do even half that good on mine.

That brace looks like a good addition. The chassis looks great!

Harry, just a comment, not meant as a criticism. I notice a good sized gap between the bottom of your mounting plate & the top of your wire main rail. Solder, by itself is a poor gap filler with little strength. If used as such, it introduces a chassis weakness. I assume this was done because the motor you used has more height than an 'FK' style motor, which the JK bracket is drilled for. You could grind the holes higher in the plate, but there's a way to fix it without taking things apart. Cut about a 1/2"-3/4" length of brass rod & lay it on the outside (non-motor side) of the gap. Solder this rod to both your main rail & the JK motor mounting plate. That rod will add quite a bit of strength to your chassis.

You called it right as usual Bill. My mistake was sanding the bottom of that plate so it would rest on top of the wire. I did this as the width of the axle was so close I felt I needed the few thousandths.

I sanded too far. I thought about adding a small rod there but was lazy. I will attack this again when I get home.

I appreciate the help and comments. This is how we keep the fun of scratchbuilding alive.

Harry, Bill is absolutely correct on the gap between the bottom of the motor bracket and your chassis rail.....I did not have the heart to mention this after you had gone to the work of taking my advice on the brace.

I think you can easily rectify this, and, incorporate another improvement at the same time..............you said that the motor rested on the bottom brass cross brace......well, ditch the bottom cross brace,.... unsolder the bracket/brace from the main rail.....screw the motor to the bracket, and place the assembly into the chassis so the motor bottom is flush with the chassis bottom...grind/file the bracket bottom so it is just meeting your chassis rail, with the motor bottom still flush.....tack solder the bracket and brace.....remove motor and complete the soldering.... re position your cross brace in front of the can so the trailing edge of the brace just meets the can front.

Re doing my chassis again??? :roll: ......a pain.......A lower cg, and a stronger chassis..................priceless!!! :dance:

To re iterate Bill's comments/advice......solder is weak/soft (just bend a piece) and any soldering joins that involve a gap are useless. The most important thing in building a strong chassis (assuming everything is clean/good flux/hot iron etc.) is to ensure that the various rails/plates/tubes are as "tight" as possible........it takes most builders (good ones) far longer to "fit" the pieces than to solder them........I know that we all want to see our creation finished, but, trust me, time spent on ensuring a "tight" fit between the parts is essential, if you want the chassis to stay together.

Hmmmmmmm.... :think:

[HomeRacingWorld]

Now what are you mumbling about? :)

Oh, I can see this is going to get crazy around here.

[HomeRacingWorld]

Well, finished it and it's not perfect by a long shot, but it runs pretty good.

[dreinecke]

Just wow. My lousy resin body is NOT worthy of that chassis! That is seriously cool work!!!

I guess I better get started on mine...
