Bottom Block

Assembly instructions are interchangeable between the 1”, 1-1/2”, 2”, and 2-1/2” GreyT Telescope Bottom Blocks.

Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.

Step 1

The size of the 1/4” ID bearings used in this step are determined by the wall thickness of tube you are using. For 1/8” wall tube these bearings will be 1/4” ID x 1/2” OD bearings, and for 1/16” wall tube these bearings will be 1/4” ID x 5/8” OD bearings.

Step 2

There should be one Bearing Stack-Up for each slot in the GreyT Bottom Block you are assembling; 4 for the 1” Tube Bottom Block, and 8 for the 1-1/2” to 2-1/2” Tube Bottom Blocks.
