View Full Version : BSR Creation (Initial Set-Ups)

March 18th, 2008, 01:16 PM
I finally have received "most" of the parts that I ordered, so I can start setting up the lower frame. This BSR will be a little different than some I have seen (mostly lower to the ground). The seat will sit about 24-26 inches from the ground, and the fuel tank will be slightly above that, behind the seat. The handlebars will be around 33-34 inches from the ground, and the footrests at 9-10 inches. The overall footprint of the BSR will be 40.5 inches wide and 44.5 inches long.

I plan on using a combination of tube and sheet to get the look that I am after. This will not be a "bang-it-out" project, and I am planning on just tinkering with it.

My question to all of you is... what height from the ground do most have to their lower frame. I was thinking about 1.5 inches in the front, raking to 2.0 inches in the back. I will be ruuning the frame on top of the axle rather than below. It won't add any clearance, but it will allow for the frame to be raked decently.

Thanks for any help.

My big ol fat ass is likin your seat Buddah. I also spy an industrial power sewing machine. Did you trim the seat? My just finished stool is 2.5 off the ground and rakes to 3" at the rear. Just right for the speed bumps in my neighborhood.

Thanks Fudd, I'm liking those measurements better... 1.5" in front was looking too low, since this thing is destined for car show parking lots. Did you notice any "settling" of the frame after the tires were supporting the weight and a rider on? I am building this for my dad (about 250 pounds) and don't want to set it at 2.5" and when he hops on... it's sittin' on the ground.

Yeah, that's my trusty Consew... as far as the seat goes, it was cheaper to buy it than make it.


...Do you have pics of your ride floating around on this site?

Im computer challanged. if I forward my pix could you post them for me. Ijust finished my ride and it was a hit last weekend in a car show; it goes into another indoor show next month. For what it's worth I'm 270 lbs and my frame is 1 "1/4 instead of 1" my finished ride hight is what I gave you. It's sweet Man . -Fudd

Now that I have my desired ride height... 2.5" in front, raked to about 2.75"-3.00" in back (2 degrees spanned over length), I decided to work on the spindle area... since that covers alot of variables.

I purchased the "U-Weld-It" spindle kit from BMI. It is actually of decent quality. I had to order another bolt, since the "kit" comes with different lengths initially. (I was told for an off-set Kart chassis).

I started setting up the parameters so I can make a jig for the "front beam". After all was done and said... here is where my front end will land.

Camber: 10 degress negative
Caster: 08 degrees positive
Ackerman: set to True

After the spindles were TIG welded, I set everything in their "rough" setting and used some welding rod to check the positioning... thankfully, everything "acted" as it should. Now I can make a jig and move on to getting this thing sitting on its own shoes.


...Fudd, I shot you an email.

Boys I see a top quality piece coming!!! All laid out square on plywood fixture, top of the line parts and the welds look mighty fine. This build will be over the top I'm sure. Keep it comin Bubbha.:cheers:

Thanks c.schulz, hopefully, it will turn out as I have envisioned. I have the entire stool "built" in my head... so we will see if it looks similar to what I have "cruising around" in my head.:dizzy:

Started laying out the front "beam" area. I am going for a very mechanical feel to this stool. I "see" it being Alien looking with odd shapes. I plan on using a combo of tube and sheet to pull the two designs together...

This will give ya an idea of what I am shooting for... (It's rough, but in the right direction) The two runners extending will be cut just behind the "beam", so it will sit at 8 degrees castor and a 2 degree rake, front to back.

I was wondering when someone would take BSR building to the next level and design. I really look forward to seeing what you do next.

I only have two concerns. Will you do something similiar with sheetmetal for rear axle support closer to the wheels? Will the tubing be strong enough to support you on a barstool or are you planning on using sheetmetal in this area also?

Just curious....

BuddhaBomb
March 27th, 2008, 12:38 PM
Critter, I haven't completely figured the rear out. I attached a pic to show where I am heading. The rear "arms" will go up at an angle, so the frame will sit on top of the axle and the axle hangers will be below - a "drop-out" axle so to speak. I have a couple of ideas as to the design, but haven't worked all of the details out yet. My "hope" is that the "rear arms" have a "wing" feel to them... if that makes sense.:eek2:

Still working on fitting all of the parts (sheet metal) on the front "Beam". Also had a chance to start welding it up... hopefully, will be able to have it sitting on its front shoes soon... One thing about doing a frame such as this, it takes alot longer than simply bending up some tubing.

This thing is gonna look great. I bet it keeps you awake at night wondering how its gonna come out. dont worry i bet it will look great keep up the good work

BuddhaBomb

Thanks for the compliment, I appreciate it.

Now I am at the point where I am committed to the design, but also at the point you think to yourself... "What the #%@! was I thinking."

The front beam is taking a little longer than I wanted... there are a few individual parts that need to be fabricated yet. Here are a few pics of where it stands now... I will hold off on posting more until I move to the back section.

BuddhaBomb
April 14th, 2008, 10:10 PM
Finally have it sitting on its front tires... Had a chance today to start "mocking-up" the items that will set the "look" of the stool. Still am playing with height and placement of the handlebars and seat. As it stands now, the seat will be around 24"-26" from the ground. On each side of the seat, there will be a 2.5# NOS bottle... so the height may be adjusted an inch or two.

Also, started roughing out the rear arms... gotta love pencils and chipboard. One day I will have one of those schnazzy 'puter programs. The rear arms will be similar to the front beam - sheet and tubing.

c.schulz
April 14th, 2008, 10:36 PM
Looks great. And the tires are shiney too. Where did you get the seat from? Ive been trying to get one off eBay and the price is just to high. How much did you pay if you dont mind?

Chris

BuddhaBomb
April 14th, 2008, 11:02 PM
Shiney Tires?... yeah, cleaning the wife's car and had some armor-all left over and figured what the heck...

As far as the seat goes, I just bought the retro-fit part (just the seat) from a Guitar Center nearby. You can also buy them online:

http://www.guitarcenter.com/Roc-N-Soc-Original-Retrofit-Throne-Top-101198174-i1165875.gc

They are a little pricey (69.00), but after you see and feel it... it is well worth it. It is about 3 inches of foam and the top is velour... very nice. Plus I like the way it is cut-away for the legs.

Had a chance to work on the BSR and started the lower rear frame. I am making it in multiple sections that will end up being welded as one piece. Finished cutting out the parts, reinforcing the lower tops, and side pieces. The lower frame will be 1.25" in height, the same as the tubing. The rear upturns will come off of the rear "pad" and go up over the axle. The axle hangers will be welded to the bottom of the arm and make for a "drop-out" type axle... or at least I hope.

BuddhaBomb
May 8th, 2008, 01:37 AM
Finally have the bottom section complete and moving on to the rear area to attach the axle. Initially, I was going to do a "wing" type design; however, now I am opting for a cantliver design. That way the rider can adjust the frame and axle to "track conditions" and rake. The adjustment will be done by two 1/2" heim joints.

(Sketches for RED since he likes them so well:cheers: )

BuddhaBomb
May 13th, 2008, 02:52 PM
This pretty much should end up this thread on my initial frame design. I had to re-design the rear cantilever system so I could incorporate an adjustment to the rear axle. This design will allow a 1" adjustment to dial in the rear axle and rake of the BSR, using 1/2" heim joints.

I will use the same process to build the "rear arms" as I did for the front beam. After that it will be simple brackets to hold the battery for the NOS and the master cylinder, etc... Then I can get rid of the plywood layout and start building the fun things.

Thanks alot for everybodys help, I appreciate it... And most importantly, thanks Mike for having the site.:cheers:


...hopefully, this thing gets done in a timely manner.

BuddhaBomb
May 28th, 2008, 12:14 AM
OK, this will be the last post to the thread...:laughing:

I am setting up the ride height of the seat and keep coming back to 24-26 inches. Does anyone run their BSR seat that low? And if so, how does it feel?

...Should be sitting on all fours by the weekend.

May 28th, 2008, 12:05 PM
Im looking at cutting mine down to about that height. Its just to scary sitting higher and running around at 40mph. Theres no damn seat belts on these things. Your ass starts to pucker to hold on.
I would also move the seat a little forward or you will be riding wheelies all the time. The height looks good for the proportions.
Hey I really like the battery hold down. Could you make me one just like it??? If yes then also tell me where to get the battery or the dimentions of yours.

I was wondering the same thing... what is a comfortable ride height for the stool?

Also buddha how did you Fab up the frame? It looks awesome good job

BuddhaBomb
May 28th, 2008, 12:42 PM
Thanks for the input, I appreciate it... Good call on the seat placement, I will move it a little forward. I am going to keep it around the 24-26 inch mark for all of the reasons mentioned above.

The battery is an Odyssey PC545. It is the battery that alot of people use for their "Battle-Bots"... it has a long reserve capacity. I am working out the final parts to it and once done I'm sure I can bang out another. The battery will power the nitrous system and any little lights I have... then just put it on a trickle charger.

ChevyBoy_0, I make all the parts with cardboard templates, then when I am happy with the movement/design I trace it onto sheet metal and go cutting with my trusty jigsaw. I am looking forward to more pics from your thread... I like what you are planning on doing.

Where can I look for the battey? just any Odyssey dealer or on line? On the hold down just let me know on the $ amount. I have a paypal account if that helps.:thumb:

Here is where I bought mine from:

If you buy from them, be sure to call to order it rather than buy online... as you can get it for a little less:thumb: . Also, Odyssey make a bracket for the PC545, but I decided to make one with the dimple dies instead. Let me know if you pick one up, I should have the bracket figured out soon.

For the rear suspension part, are you planning on running a swingarm style suspension? I noticed something that looked like shocks connected to the "Wings" and the frame...

BuddhaBomb
May 28th, 2008, 09:01 PM
I had some mountain bike shocks that I was thinking about using, but I wanted something more solid since it will have a nitrous system on it. I decided to use a left/right 1/2" heim joint. That way the rider can dial in the height from side to side... and surprisingly... it actually works.:cheers:

...still need to cap off the 1.25 ends, but that will finish up the bottom frame design. Now I can start moving upward.

Hey the frame looks great! Don't forget a track bar on the rear axle. Otherwise it will "Dog Leg". Otherwise, awsome job on this piece!

What do you mean by "Dog Leg"

ckoczara
May 30th, 2008, 04:13 PM
What do you mean by "Dog Leg"

Dog Legging is a slang term used to explain how the rear axle fails to follow the front tire tracking. What happens is the control arms and rod end links hold the axle in the up/down directions, but the track bar forces the axle to stay in one place side to side. The track bar should be positioned from one of the upper control arms to the fixed, portion of the frame. The control arms don't have enough strength to do this with all of the leverage being produced by the length of the arms and the solid axle. Without the track bar, it could, and most likely will bend the flanges on the control arms. This will produce "Dog Legging".

I attached a picture of my chassis. Notice how the bar extends from the frame rail to the top of the axle tube. Also note that this is an adjustable bar at both ends. Without this, the ladded bars below will allow the axle to walkout from under the truck.

Thanks for the help... I was looking at installing some sort of panhard bar set-up, but haven't quite figured out a clever way as of yet. I am still figuring out how to use only a single bar from the steering shaft to the seat... sort of like a suspended seat. Then I will cap off the rear end and look at what you mentioned with either a bar or some sort of wishbone dealio.

Billetboy, that is sharp looking. Will that mount up to a typical three hole flange? Also, could it be mounted up without the lower "ears", basically just a circle that gets bolted up with an 1.25 bearing? I have another project in the works and was wondering... also, PM me a price on those.

May 30th, 2008, 11:04 PM
this one was going to be mounted by the lower holes there are 4 holes i was only going to use 2 to mount it and the other 2 were if i wanted to move it foward or back kinda of an adjustment so if i ran out of chain adjustment i coud just move the axle and get all the ajustmet i need but these are not going to be used i came up with a frame design the has the bearings in the frame and not bolted to it will post some pics of this soon
