ROUND NO.1

 

"PAPPY'S"  formula F-1 thingie project

 

Fellow slot blogger has a neat project a  formula F-1 thingie , since many pm chat he has come a long way with his own vacuum table up and running, but has run into some small problems not being able to get good pulls.

 

 So he sent me a resin body he made and was using one to pull bodies from but with some success.

 

Now what  I have done was to make a silicone mold of his resin body. I will cast a new plug and drill the vent holes and pull a few bodies.

When done I will send Pappy the this mold so he can use it to pull some bodies from and hopefully he can pull some good bodies .He then can compare my mold with with his mold and help guide him along.

 

The follow photos can be viewed as a how to step by step and self explanatory.

 

Setup and making a silicone mold to cast the resin vacuum mold

It would be a great help if you could indicate the specific materials (and source if possible) you are using to make the various molds. Thanks!

Here ya go;

 

Best clay

Silicone Compatible Modeling Clay

Also mold release friendly.

Special synthetic clay that will not contaminate silicone rubber. Use for containing flow of RTV during mold making and for making simple molds. (Place a little #80966 Industrial Talc on the part and press it into the clay. Then carefully remove the part and pour resin into the cavity). 1 lb.

 

Mold silicone

OOMO 3O

 

Resin

QUICK CAST

ROUND NO.4  final compilation

Pappy's original mold and his clear body.

Close up of his original body,

Z06.jpg

New completed mold with a new uncompleted mold. The uncompleted mold is for practice drilling vent\draw holes, polishing out and finishing the underside channel lines to match the finish mold. The original mold proved hard to remove a vacuumed formed body. The new mold as an example in hand will help Pappy to see how to finish the mold draft angles and to direct the forming plastic to prevent webbing and how the body will come off the mold.

 

Z07.jpg

Soon this mold to body example kit will be on it's way back to Pappy so he can continue his vacuum body making adventure. By providing hand on examples will make it much easier to complete his objective.

 

Good luck and it was a pleasure to help out, as this is what Slot Blog is about.

Gene,

 

I can't thank you enough. You've already taught me a lot.

 

Wait till you see my next project, I think you'll really get a kick out of it. Hope to get it in the mail tomorrow. All I need is your input on where to drill the holes.

 

Thanks again.

 

Pappy

Bill, next time we race the Formula Ford's I want to take a picture of all the cars everyone has with and without the bodies just so everyone can see all the different variations of chassis. One guy has over 20 of them, I have 10 of them. They started out using popsicle stick for the main rails and some guys still do. The chassis have to be made out of wood or plastic (no brass or piano wire). We use the little FF050 motors that cost $1.49 each, we run them on 13.6 volts and I haven't seen anyone burn one up yet. They run faster than a lot of 1/32 scale cars.

 

Here's our rules, Dan Dyke started this class, made the first resin bodies and the rules. My PETG body is now legal, it's just not in the rules yet. Plus we allow any kind of wheels as long as they are 8mm x 15mm and any make of 1/32 scale crown gear. We all run silicone tires.

 

Current SlotRods Formula Ford 1:32 Rules

Either Dan Dyke’s resin body or Racin’ Ross’s 3d printed body

1) No metal in chassis except running gear, lead for weight, and brass for reinforcing the guide blades or to make an axle housing.

Any type of solid metal, wood, or plastic bearings may be used but no roller or ball bearings may be used.

2) Clay or lead is allowed for ballast

3) Any pinion that works with the motor is allowed. Suggested pinions are as follows:

a. Scalextric makes a variety pack of pinions that are blue and come in a wide range of sizes. These are going out of production and

so are becoming harder to find.

b. BWA makes gears that are the correct inner diameter of 1.5 mm.

c. 2 mm inline gears can be used but you will have to make or buy an adapter sleeve.

4) Crown gears: This rule is restrictive to keep down the cost.

a. SlotIt crown gear -- they may be lathed (this can be done in the car by holding a knife edge to the square edge) or drilled.

b. Ninco F1/CART Crown gear.

6) Plastic, wood, or circuit board may be used in the chassis. Carbon fiber plate and rods may be used for the chassis but not the

axles. JB weld may be used.

7) The narrowest of the SlotIt plastic rims on the front and rear. The narrowest SlotIt aluminum rims can be substituted on the rear.

8) Spec tire FOR OFFICIAL RACES may be designated by the track owner - these will be provided for $2.00 a pair.

9) Any commercially available guide may be used, but must be identified on request.

10) Must be painted

11) Winner may be asked to tear down even if nobody cares.

12) Kysan/Mabuchi 11170 series motors

13) Wheelbase 2.875 to 3.125 - 3" is ideal to shoot for. The rear axle centers on the back edge of the body. TRACK: I know track is

center to center but this is easier to measure.

Outside to Outside of the Rear Tires --- 2.125" (.125 = an eighth of an inch)

Outside to Outside of the Front Tires --- 2.25" (.25 = a quarter of an inch)

14) Rules can be changed after a race by me, but of course you can make suggestions. Nobody gets rules perfect the first time. It

takes time to work them out.

15) Driver and steering wheel must be included.

16) No hypoid gear arrangement may be used.

17) Axles must be 3/32." Front wheels may rotate independently.

18) The car should record zero down force on the magnet marshal and no magnetic fields should be discernible in other areas.

Magnets are allowed on top of the motor to hold the body in place. For specifics talk to Dyno Tom.

19) THE TIRE RULE #2 (See #8) --This is the hardest rule - the tread width should be .350" wide- this does not include the rounded

side wall. Height is not set unless a problem develops from this.

20) I hope I don't need this slot.

I would like to see some photos of these cars & their chassis when you have the chance. Speaking of Dan Dyke, I haven't seen him post on any of the slot car boards in a long time. Is he still with us?

Yeah, he's still around but hasn't raced with us for a long time. He's talked about it though. We still keep him in the email loop.

My box of goodies arrived today. I can't believe how nice these molds are and how nice the PETG bodies that Gene pulled from the molds are. Pictures don't do them justice. I can't wait to pull some bodies with them. Only problem is I'll have to throw the one's I've already pulled with my mold away. LOL

 

Thanks a million, Gene

 

My box is on it's way to you, you should have it tomorrow.
