Nice, what welder are you using?

It's an older Miller 110v machine--oldie but goodie!

Thanks George...The only lessons were looking at your build!!!

Thanks for the info on the rails...I won't cut them short!!

Are you running a brace across the back? If I install one I'm 100% sure the sprocket will be be hitting it. So..That wouldn't make much sense installing one then hacking it for gear clearance!

My thoughts are that the tranny plate will aid in the support for the back half and may I install one cross brace behind the tranny plate as far back without causing interference with the chain, brakes, and sprocket.

As always...time will tell!!

I don't run a piece across either the front or the rear. Since I have the puter working again I will try to get some more pics up. to give you an idea what I have done. I do weld the rear plate on and weld all seems on the inside of the frame. Pics to come.

My thoughts (I'm sure I'm wrong) would have been to leave the back as a bolt on piece (more securely than the stock self tappers). I figured it would make gear changes and such a little easier.

Useing a craftsman chassis mybe but I am using a kart style hub and split sprocket, 6 nuts and swap. On jack stands of course. Its part of the chassis a main part and even botled more securely it will allow some flex to some degree. I have found either make em rigid or let em flex inbetween doesn't work. And with the speeds we running now a real fexy chassis is not the best anymore. Flex will never stay the same. WHY, because as it flex's it weakens the metal over time the flexing continuely gets worse to the point of even having stress cracks and fractures in the frame. While the whole time you are chasing the setup because it isn't staying the same. Does this make sense.

Makes 100% sense. So if I weld my back plate on this will not cause any "ISSUES" during a tech inspection I hope......and will you slow down with your new build!!! I'm trying to keep up! LOL Grin

Quite honestly I only got about 5 hours in the build so far, IF I have everything in front of me I can build a complete MTD racer turn the key drive away in two days. I am on dail up its took me this long to load all the pictures. And welding your plate on will cause no issues. Do all the welding inside makes a cleaner look for the out side.

Thank for the info!!! True..I only have about 3.5-4 hours into my build..Most of the down time is trying to find a good deal on parts and waiting for them to arrive!!

Well, got a few more things in the mail today......so I started the installation of the rear axle cassette holders.

First thing was to grind off the surface rust so I had a nice clean area to weld onto...




Next was to mark the centerline of the old original axle and to figure the height that the new axle needs to be mounted. The new rules allow for a 4" minimum ground clearance. I set my at 4.250". I will be using adjustable cassettes for mounting the axle it will allow me to TWEAK an extra 3/8" either way.




Next I measured and marked the cassette holder to find the centerline of the holder as if the cassette was installed in it's center position.




With the marking made on the cassette holder, I was able to place it right onto the frame of the mower right over the centerline markings I made earlier.




This was squared up off of the bottom of the frame.




Cassette holder was clamped into place and tack welded at four points.




Clamps were removed and cassette holder was final welded onto frame.
Frame now needs to be cut out for installation of axle!




Here is a pic of one of the adjustable bearing holders/cassettes!




That's it for now...Ran out of welding wire!

Looking good...

I like the "measure, mark, square, clamp and then weld routine...

Beats the heck out of "slap and tack and check it with a tape measurer"...and then have to grind 'er off cause you tweaked it by 1/4"...

Ain't that something with the wire...??? Roll looked full this morning...Cept I usually don't run out untill saturday afternoon...after all the parts stores are closed... mad
