A toy for a BIG boy

[nine fingers]

I have been requested to make a D6 Caterpillar Bulldozer, about a 1943 model fitted with hydraulic workings of the dozer blade which were not available until the late fifties. I have put this in the toy section as I don't wish to create any problems as it is not true to scale.
The wheels and indexing of gears has been covered before on other models, now for the links , they are 32 x 8 x 8, the end halving was done on the router table, pivots drilled one end 4 mm the other 11/64,the scallop in the top edge was done using the same block that held to do the ends, a jig was made to round the ends on the disc sander.
With the number of operations ( 2500 plus ) to do these links I decided to make two TOYS at the same time, one for myself.
Some photos of the router set up, jig for rounding ends and one of the links completed on the wheels to get the axle spacings. John.

The more you do of these, the more technical they get.
Obviously the holiday has re-invigorated you and we are in for another masterpiece (or two).

Machined the track sections out of pine 25 x 11 mm, about 7m cut to 500 600 mm long , machined on the router table , various cutters about 7 or 8 times over the table. Cut to length 43 mm,sanded any burrs off and glued to the links with super glue.
Also made the bearing pivots for the idler wheels , 16 off. John.

One has to fully admire your skill, craftsmanship and PATIENCE'S to put this lot together John....
VERY WELL DONE seems to not be an adequate complement...

I couldn't agree more Crowie.
John certainly produces work at an amazingly high level.
It's just inspiring seeing the amount of skill being displayed.

Age is no barrier when you have the skill.

That is, not surprisingly, outstanding work. I love learning from the masters! Thanks for taking the time to show us "how it is done".

A few days in the workshop, made the main wheel supports and bearing blocks , idler wheels and axles. Dry assembled , rolls over a mat very easy.
When I can get a warm day all the pieces will be sprayed with lacquer. John.

It's just a pleasure watching craftsmanship at this level.
Really enjoying every moment!
