Projects Toymaker's Twin Engine Dragster Build

HeHeHe, yep! Thanks Josh, Rocky

 

Before going any further with the rear end mounts I thought I'd better check the bell housing alignment and I found it was off by .020". So off it came, drilled the mounting and pilot holes out and got it within .003", then made some plates with the dowel hole diameter and welded them to the housing. While I had it off I also straightened the trans up to allow the "Top" shift to clear the frame rail. All back together and time to fab the rearend mounting.

 

Wow Roc don't you ever sleep? Great job and keep up the good work its coming together!!!..............
We will be back in town tomorrow or tues talk to ya then.........

 

After consulting with my wife Tamara I got the okay to dedicate myself to the Twin and have a roller by the March Meet. She even sent in the entry today, an Angel I tell you
No pic's but I made the engine mounting tabs, welded them to the frame and drilled the motor plates, straightened the rearend housing (heat shrinked) so the alignment bar is centered and started on the rearend uprights.
I'm also starting on the front end, machined my F-1 spindiles down to pass car specs and started on the pieces to mount the frontend to look like a torsion suspension. 2 weeks, here we go!!! Rocky

 

Great news! Keep after it!

 

Tonight I fitted the X braces between the engine and rearend, I want to get all this area welded before I mount the rear end in case of any movement due to welding. I also installed a Xmember below the 3rd member for the anti-rotation mount and shaped the frame to frt axle links that will simulate a torsion set up.



Also shown are the F1 spindles machined to car specs and the Harly wire wheels I plan on using.

After cleaning up I had to set a tire up and take it all in

 

Nice progress! I'm loving this build. Very cool that your front tires say "Twin Tire" on them, was that deliberate?

 

Keep cracking away at it, that last mockup surely must get you excited, looking forward (as I'm sure you are) to seeing it on it's wheels on the ground.

In a evil/twisted kinda way I wonder which would win over the 1/8th, this twin mill or your HA/GR?

Cheers,

Drewfus

 

Wow.

all I can say is "WOW Roc" ....................

 

Love this build - I'd be interested in buying a "twin" package of all the twin specific parts you made (engine plates, bellhousings, trans, etc.) to build a twin powered show rod.

I had forgot all about the tires, we had bought them a couple of years ago for our HAMB Dragster and didn't make the connection

The TWIN better come out on TOP

The design I chose wouldn't be good for any application that would require running the car any real distance IMO but I have the patterns, Rocky

 

Another productive weekend finishing some of the more challenging parts of the build. After fitting a couple of uprights in the drvers area (still need to add the kidney bars) and fabbing the anti-rotation bracket I dove into the front upper frame rails.


The upper rails need to be removable to get the engines out so I came up with this connection...............


The connection will require the lower frame to flex, allowing the upper rail to seperate enough (about 1/2") to uncouple the connection. The upper rail connects to the engines where the old front mounts were.

Once the upper rails were completed the task of "Pie" cutting the frame rail ends was next, and really had me intimidated.

The rails are 1 3/4" (lower) and 1 1/2" top so I started with marking 1" off the lower and 3/4" on the top. After cutting it short of my mark and grinding and grinding the measurement turned out perfect so the other side went much quicker.

All tac'd together and time to fish mouth the frame end for the "Torsion" tube. I measured for wheelbase and dilled 1/4" pilot holes on both sides of each rail then cut with a 1 3/4" hole saw. Having a piece of metal for the holesaw to rest on really helps with keeping your cut centered.


Cleaned up the cuts, final fitted remeasuring the wheelbase and tac'd in the tube.

After all the work I had a little time to play and mock it up

With any luck it may be running by May!

 

Damn Rocky...that thing is going together quick. How many cases of Red Bull so far?

 

I've been keeping it to 1 12oz a day, I don't want to get addicted
Tom, I've been trying to put into words my Tube bender build but it was a build as I went project years ago. I started with a Harbor Frieght Pipe bender, bent a piece of 1 1/2 pipe I think and made my first die from that. The piece was fitted to a piece of 1 3/4" tube then plated it and ground it to be 1/2 of the tube diameter. Then I took another piece of "pipe" and sliced it in 1/2 to make a "troff" ? SP, plating it something fierce to eliminate flexing. With that all done I used the hydaulic jack that came with the bender, made a frame and wala, a very eXspensive bender that I could of bought 2 for the time involved. I don't even know the radius, it just looks good to me and right for the older look I like
I learned somethings along the way with it that only could be taught (to me anyway) by the build but man I remember thinking if the damn thing don't work I WASTED a BUNCH of time. Rocky

 

Badass!

 

Hey Rocky! I've subscribed to this thread and wanted to tell you how your efforts and skills are quite impressive! Man, when it comes time to fire that twin mill up in the near future, you need to do another You Tube video to satisfy all of us HAMBER'S cravings for the sweet sounds of V-8 POWER!! GREAT JOB!!!

 

What is the finished wheel base?
Tom S.

 

Looking good! Nice progress, I dig the intake for sure!

 

Thanks Guys and the wheelbase is 120".

 

Well Roc I got started today, what do you tink, I will add a coulpa mounting tabs if you need them or just use 3/4 clamps..........Oh the outlets are 5 1/2 on centers to match the manifold.......




Happiness is a big pile metal shavings....................

 

What machine is that?

 

OK Carl......... nuff showing off now !

What machine is that?

LOOKS GREAT Carl, especially hooked to these!

Yep, it's on the ground and ready for the frt axle build but here's the way we got here from where we last left off.

Lee welded what he could after I completed the front frame bracing.






The RH rear end bracket was a little more than a 1/2 RD cut as it had to follow the contour of the center section, so I make a little "Widget" to transfer the shape to the plate. Mark your project with line to follw to keep the shape transfer correct. I've used this metHod before on wheel tub projects and works really well and I have layout dye but a good "Magic Marker" works great!


Once I was happy with the rearend alignment the rearend housing was welded to the brackets after they were bolted to the frame, I used 3/8" bolts for now but they will be increased to (4 per side) 7/16" when finished.

My alignment tool is all scrap pieces including some old pistons
With this all done I cut some old axles mounted the wheels, and put her on the ground!



And this ones for you Tom

 

Awesome work. You are cranking this badboy out real fast.

 

Outstanding work guys

Can't wait to see first action video of this!

the roller is money! I love it!

 

Awesome progress every time I check this build...lookin great!!!

 

WOW!!! I just found this thread tonight and read it alllll the way through. Super job!!!
