This is a Caterpillar 299D Compact Track And Multi Terrain Loader, otherwise known as a Bob Cat, another toy for a big boy. The scale is 10 to 1
same as previous models , overall length will be 3850 mm ,with bucket on the ground.
The tracks are 3 rows of links the outer row 10 x10 , centre 20 x 10 all 18 mm long. Pivoted on 3 mm diam skewers , 9 mm c/c off holes.
Rebated all pieces to from the treads on the router table (see jig)
3 mm holes had to be very accurate for the links to fold, ends of links quarter rounded to allow folding.
Final shaping of the treads was by hand.
62 centre links plus spares ,124 outer links plus spares ,2000 operations .
Tracks assembled. until next time John.

Might be a bit tight on the shed when finished.
More very precise work there John.

Very interesting tracks.
I really like them.

Some progress on the bob cat, painted the tracks with mat black , as close as I think the rubber tracks would look like. The chassis with the rollers, the main roller wheels and the gear , assembled for the time being. Tracks can be removed by withdrawing one of the pivot pins. John.

A fantastic start to the model, I,m in for the ride

Made some more progress on the toy. The cabin frame is made of blackwood, all the joints are held together with Loctite 401, its so easy to use , just a few seconds together for a firm joint. Some extra work on the chassis and fitted the cab.
The lifts for the main arms and small ones to tilt the bucket. They both have sponge rubber on the ends of the plungers to create friction.
Glued up the shape of the arms , butted together with loctite and pinned with tooth picks . Will get some more done tomorrow . John.

John, I am in awe of your craftsmanship sir, beautiful work..... thank you for the photos & notes..cheers, Peter

PS - Do you still have to store Loctite 401 in the fridge once it's opened???

Hello Peter, Never stored Loctite in the fridge, I use it all before it go's off. John/

Looking really nice John, as per usual !

Can you bring it along to the next meeting ?

Thanks for the info on locktite - I have always used 5 minute araldite for a lot of components. Where do you get your Locktite from in Geelong - if you don't mind me asking ?
