Title: Building New 225" FED Need a little help
Post by: nitroscott on August 13, 2017, 01:11:04 AM
Hello and thank you for letting me in this cool site. I am building a 170" FED Stack Hilborn injection, trying to keep it looking like 60's JR Fuel Car. I have 10" wheels, Mark William bend kit and blueprint. I have most everything I need except font wheels and little stuff along the way. My differential turned out to be too short so now I have to build one. My housing will be somewhere around 34" and I will need 1.5" 35 axles.
I have a group on FB called "History of JR Fuel" https://www.facebook.com/groups/707306692694561/
I started this group to see if I could get some help building this FEDragster. No one seems interested in following. I have a few questions to start. 
I have to splice my shoulder hoop what size rosette holes should I use and how long should my inner piece be?
My mid motor plate is SBC Mark Williams and has a round hole in the bottom. Can I cut a slot at the bottom of the motor plate so I can get it in and out with out removing the block from the alignment bar?
I would like to keep this car looking nostalgic and I need to pick a tire out. I wanted to keep the tire from being to tall. If I used a shorter tire will I be able to keep the diff off of the lower rail and what tire do you all recommend? Thanks
Update: Car is in the process of being built.

Scott,
        glad to see that you are actually starting to build the car. You need to get a copy of the SFI spec before you start on the chassis. It will tell you all about the splice criteria (and lots of other things as well).
  Although you could slot the mid plate it is not a very smart idea as this is the firewall between you and the motor. In addition it is a good idea to have a contiguous piece tying the lower frame rails together. Does the MW mid plate come pre notched or is it just a drilled blank? If it is notched you should not need to be taking it in and out while building the frame--just bolt it up and run the top frame rails through the notch. If it is a blank you will need to mock up the frame to determine where the rails are going to be and then notch the mid plate and bolt it in place (after removing the block from the alignment bar). Sorry if that is too much work but it takes some effort to build one of these things.

Roo

Hey Keith, Yes I am sorry it took so long to get this FED started. I agree with you don't want to cut the mid motor plate because of strength and protection. You are right these things are a lot of work, not just off the shelf put together. I have the backhalf jig built enough and the differential set up in it, seat hoop clamped down and the shoulder hoop holder built. Now I am attaching the motor plate to the motor. I have to figure out a way to post pictures on this site, when I try it says that the pictures are too big. Is there a free software to reduce the size or a way to do that other wise. Thank you for your advice. Nice chatting again.

You're most welcome Scott. We do whatever takes to get FEDs on the strip.

I am getting ready to put the final touches on the drive train set up before I cut the motor plate. Is this set up ok? I only have 7" under the motor.

Hello, Scott, hope you're OK through this storm in Houston. I'm to the Northeast side, in Porter, near Kingwood. How bout you?

If you set the motor out 39", you can use a full length PG with a direct coupler to the rear end. At 36" you will need to use a shorty glide and buy 2 extra couplers and a drive shaft and build a driveline cover.
 Engine "DUMP" has no real bearing on chassis design, Its the relationship of the rear end, distance the motor is in front of the rear and front oil pan clearence. A Mopar pinion is .500 higher than a 9" ford, so there will be more angle with a Mopar.
 Set the rear end hight with bar through the housing, install a line-bar in the 3rd member, set the block with the oil pan XX distant from the rear centerline , and set  the front oil pan clearence allowing room for a diaper so it doesnt drag when you bounce the car. Thats all there is to it

I am sorry to tell everyone that has helped me, that the dragster project is under 3 feet of water. Soon as the water drains I will start it back up. I was doing so well too getting all of these different factors to work together and got the hoops welded in. My motors, tranny's and chromoly are all under water. Thanks for all of the kind help.

My shop has recovered (thanks for the well wishes. I am starting my FED Jr Fueler project back up. I am using TF specs on this chassis no telling where it will end up. It has a 225" wheelbase with the engine out 50 inches. Should I fasten the bottom part of the mid plate to the frame? Seems like a good idea but I have never seen anyone do it. If the mid plate is fastened in four points it seems like it would support the frame better. I could be wrong. Let me know what you think I have thick skin.

I think it is best to have a chassis upright in close proximity to the block plate, with an attachment at both the top rail and bottom rail.

Post by: nitroscott on March 24, 2021, 09:23:18 AM
I read that putting the motor plate upright right next to mid plate will help seal the cockpit from fire. So it is ok to attach the bottom of the plate to the lower frame rail?

My rear plate is attached to the lower rails. Simple tab with a nut and bolt

Post by: nitroscott on March 25, 2021, 11:55:49 AM
Ok Thanks for the reply. I am going to go ahead and attach it at the bottom. The chassis is moving along pretty good, trying to get it done before the heat of summer hits. Attaching the front axle today and finish the K. I am just one 22" piece of 1-1/4 short to finish the K member, not sure the best place to get it. Years ago I used the Chassis Shop, probably use them again for that one piece among other parts. My sticking point now is how long to make my 9" housing and figure out how long the axles should be. My wheels have 4 back spacing. Jon is going to help me pick out a tire today.

Next time I do one it is going to be one tab from top tube down to bottom tube 1/4” thick, bolt at top tube and bolt at bottom tube. Motor plate will rest against the tab

My suggestion. Call Neil and Parks. Talk with Frank and/or Scott. They not only sell every piece you will need.They will giv you ton of advice. Heck I spent almost hour talking with Frank first time I called them and got ton of info and had not spent a dime with them yet.https://neilparks.com/.

They sell housing kits and in all honesty not much more than cost of materials and all the engineering is done.

Hey Paul, Do you mean a tab from top to bottom? I am puttting an upright at the mid motor plate. I could put a tab top, middle and bottom. What do you think?

I have been using N&P for a lot of parts and blueprint and I like both of them. I always feel like I am bugging people asking questions lol. I do like this bench racing that we are doing to get this thing built. I want to do something really cool on the very front like an eagle beak out of tubing. I split a 1-5/8 tube and welding it to the ends of my main frame rails and then lay the tube front axle in that half tube and weld it up. Then do the beak in front of that and use the beak as a tow hook. Not sure how I woud make that happen. Just an idea.

Yes 1.25 upright with a plate/tab that goes from the top tube to the bottom tube that also is welded to all three tubes top rail, upright, and bottom rail

The middle bolt would be largely redundant, i.e., not stressed hardly at all and unnecessary.

There is some cool stuff going on there in that picture. I am putting the motor mount brackets on last night and again tonight. I'll have some pictures after that. I went the two tab route.
