Articulated Truck

Postby Studeag » Tue Nov 25, 2014 9:12 am

Here are some pictures of the project I am working on. I've redone the plan with Sketchup for the box to have all the combined cutting angles, cause on the plans, there are not shown. The wheels are made of Oak that will be ebonized. I will post pictures when complete. I've included some pictures of it today.

I've made my jig for the wheels so I could cut left and right sections and create left and right wheels. I also made the rear axles so the suspension would be independant.

Looking good Studeag. Can you describe your wheel making process a little more? Nice work, thanks for posting.

JIGS FOR WHEELS

This is the procedure I use to make the articulated truck wheels, it is the same procedure to make any of the wheels for the Toys & Joys plans, the dimension and number of slots is different

First, I cut the blanks for the wheels ( 4 ¼'' x 3/4'') and grill a ¼'' center hole. The I use my small circle cutter on the band saw. Also I get the inner wheel made with ¼'' thick material.
Image

The jig is made so I can push it to the blade so the front of the blade is equal to the front of the ¼'' post a stop block is doing that.
Image

Then I start the cutting by turning the piece into the blade.
Image

I go all the way around
Image

Then I backup the jig to remove the wheel part
Image

I sand or machine the wheels halves and center so they are all the same size.

On the Toys & Joys plan they show how to make a jig to make the treads on the halves
Image

But they make treads on one side of the blade so wheels are all the same when assembled, you can't produce left or right wheels
Image

If you want to make left and right wheels, you will have to make an other jig to cut the other way and produce them
Image

I've produce mine with one jig, but use it on the 2 sides of the blade to have treads face to face
Image

The jig I use to make the treads is an indexer made to drill circular form holes on the press drill
Image

Image


The inderxer can be done with any number of thoots on the gear to drill any hole combinations on a wheel. The one shown is 36 tooths and can do all those hole combinations. 2,3,6,9,12,18 and 36
Image


It is made with the use of a 36 thoots gear that is controled by a spring loaded small bearing that rides on the thoots and stops the gear at each inner thoots separation.
Image

Image


This jig is made with 2 flat bearings that hold the gear and base together and keep the piece to be drilled in place and rotate, a complete free plan can be found at this adress :

I use the same jig on my table saw with a different table on the jig to hold the tire halves and removing the cover,
Image


Then placing it on my table saw on the guide saw jig at 90° and turning the jig assembly at 60° from the blade, adjust it so the blade is under the center of the wheel half, raise the blade to the correct height, then make one side of the wheel by turning the jig 36 times to make the slots and produce all of the halves of that angle
Image

Image

Image

Image


I then flip the jig assembly to the other side of the blade at 60°, keep the same blade height, reajust the blade on the center of the wheel half, then cut the 36 slots on the other side and produce all of the halves of that angle
Image


Then I assemble the wheels with a left and right halves and the center section in the configuartion I want.

The Toys & Joys plan supplies all the dimensions of wheels parts.

Alain, great looking truck. Thanks for the info on making the wheels. You guys are making me jealous. I can't get out in the garage for four more mouths. James
