Title: Shriner Go Kart
Post by: stevehuckss396 on December 01, 2022, 09:51:00 PM
Hello everybody!

Needing a break from the radials I saw an ad on craigslist for a little 1/2 scale 1910 model T. These were cars built by snapper mower before they were snapper. They are 1/2 scale and were meant to be purchased as promotional tools and expensive toys for kids. Businesses would display them in the front window of there store. Some would purchase them and then give them away like Coke-a-cola, car dealers, and companies all over the globe.

Well I bought it. Then I bought another one. And then another one. 3 grand daughters so I need 3 cars! Well all 3 are now fixed up and we are waiting for the memorial day parade in may. I have no more room so I cant buy another. So I decided to make a 1/3 scale copy. I have a spare 1/3rd scale engine block and it is the same engine that these had on them new.

So here is the plan. Build the cart complete then actually finish the engines I started years ago.

I have been at it for a couple weeks so I have the frame done. I did it in brass so it would solder easily. The body is well on its way. The hand controls are well on there way. Yes there are no pedals. The tow truck is this way so on the full size car I added a brake pedal. This morning I started on the front axle and all the parts to steer the vehical. Hope to actually finish this one some day.

Will the MiniShriner be RC controlled? Or do you need to teach your shop elves to drive?

Shop elves only. It is meant to be a fully funtioning model like the real thing. Hopefully it will turn out that way Haha.

That awesome Steve!   I remember them running the cars at the 4th of July parade in my town.   I always thought they were cool

I get that. When I got a visit from the police they had a disagreement as to who had to sit in the red one. They wanted to sit in the black and white.

The police car has a kill switch, push button start, head lights, tail lights, brake lights, emergency flashers, and a siren. That one is fun to drive.

That looks like a really fun project! I forgot is that a Brigs or Tecumseh single?

Tecumseh 3hp. The same engine that is on the little mini bike. The only difference is the exhaust port exits the side of the block. The full size engine exits the rear of the block next to the carb. Should work out fine.

Hugh, they are the 3 in the fancy cloths.

Nice work on the gearcase, Steve.

A stepper driven rotary table on your CNC mill will work well for cutting gears.

Couple of nice bits of CNC work on the axle and Gear casing, if you have "pencil" and an option in your CAM that should remove the "weld beads" that someone else mentioned.

Also looking forward to see how the Fenders turn out.

No welding. Must be marks from the tool.

Some of those weld beads are too much backlash in my 16 year old machine. I purchased the parts to upgrade the electronics so I can switch to Mach4. At that time I planned to deal with some things that have popped up over the years like backlash and an old motor. The motor finally failed and needs new brushes. I can put oversized balls in the screw to tak up the lash. She needs some love but I keep getting paying jobs engraving so I keep putting it off.

Thanks Dave!

I understand the concept I just lack the equiptment. I tried it on the CNC but lack the horsepower to make the cut. I setup on the mill but the cheap R8 cutter holder I have is so out of concentricity that it seemed like only 2 teeth were making the cuts. I spent a few minutes making a R8 holder from scratch so the cutter now spins with no wobble. I have been waiting for the #3 cutter to come in and I will have both. Then my rotary table has a chuck mounted to it. I chucked a blank and gave it a spin. 0.007 runout so now i have to address that.

I decided to change gears and get the wheels figured out. I made the rims and decided to make the spokes out of hardwood. Went to the rack and found the collet I thought was a 3/8 square was actually a 5/16 so that is on hold now. I dont see much getting done before the holiday so now im looking at 3D printing these fenders. I scaled down the center section and will make a test print sometime soon.

Other than that its going good!

Got tired of waiting for involute cutters so I went down to the home depot and picked up some oak dowels.  Cut out 54 spokes but only needed 48. Still trying to decide if I'm going to paint the rim and spoke red or maybe just clear coat the spokes. After u figure that out I'll do it then epoxy everything together. Then the center can be machined flat and bored to accept the hub.

A really fascinating machine, yes, I do have the plan on my bench since years ago, but a single tooth cutter works very well too !
amazing gear box, superb!

I just posted 2 videos on YouTube. Step 1 was to cut the 1/2 inch diameter down to 1/4 and dress the end with a tapered tip so that last spoke can be put in on an angle and worked into place. First try they were way to tight. So I took a WAG and recut them 0.010 inches shorter. I scrapped the bottom edge with a razor blade to break the sharp corner and was able to work and tap the last spoke into place. They are nice and tight like a real wheel. Now I have to get them apart again to cement them together after I decide how I'm going to finish them.

Oh yeah! Once the cement sets up I still have to face the hub area from both sides to smooth out the surface and bring the hub to thickness. Then I will reapply what ever finish is used to that area.

Search for stevehuckss396 on YouTube and the video will pop up. I tried to post a link but something didn't seem right. I'll try again.

Well the glue has set on the spokes. I machined the center of the spoke circle to width and bored to accept the hubs. I now need to drill the holes to bolt the hubs on but it's time to eat, drink, and be merry.

Happy new year everyone!

Jo, Thank you for the edit!

I'm taking a break from 3d printing for a while so I decided to take a look at the steering column. Pretty simple pieces so I was able to make a lot of parts reasonably fast.

Also thanks again to Don1966 for the spread sheets. I made a 36 pitch gear today that I couldn't buy. I will make the big gear tomorrow.
