Ripper Tooth for the Backhoe

[threepiece]

I simply couldn’t get myself to spend $1,000 so off to the shop I went. Here the tooth is about 90% complete. I have yet to install the tip but I need to check clearance to the stick of the backhoe 150 miles away.

This is for my JD 110 TLB.

After making templates from cardboard I went to cutting a kit. I did buy a replaceable tooth tip shown on the left.

The tooth is made from 3/4” Hot Rolled trimmed on the band saw.

The hub is made from 4x8x 1/2” wall tube.

Here I am milling a slot for the tooth to pass through.

Here I am preparing to drill the corners of the trim for the quick coupler ears. The template has all the information needed. I can use this template in the future.

Cutting with a hole saw. Notice the two drain holes I cut. This prevents chips from loading up in the cut and allows uninterrupted cutting. Much faster this way.

Finishing the hole to size with a boring bar.

Showing how the tooth passes through the hub to be plug welded on the end.

The tooth is welded inside and outside the hub.

Today I will be fitting the tip on the tooth as I am here with my tractor. I plan to show how that goes later.
