Table Saw Casters -- Mobile Base -- One-handed Operation

Table Saw Casters -- Mobile Base -- One-handed Operation

Objective: Easy Movement.

Bought casters -- no definite plan.

Watched YouTube videos.

Decided on 1-1/2 lift.

Mounted boards, may regret placement.

Stared at it for a week or two.

Thought about mechanisms. Wanted one handle to do all work.
Considered push rods, attaching something to upper cross braces.

Watched more YouTube videos.

like: high lift, cam mechanism
dislike: handle design

Decided on cam action.

Mounted 2 x 2. Used oak bearings to keep edge from splitting out. Notched oak to make height equal to pine.

Needed 2-1/2 inches of lift (in addition to 1/2 of existing 2x2).

Used compass to draw arcs. Messed up first time (wrong pivot).

Converted to millimeters, made chart, shot for 2-3/4, flatten out to lock.

Marked paper, sketched arc.

Cut out cams. Attached cams. Attached handle. Applied wax to cams.

Chamfered boards. Success!!
