The following reflects building and using the sliding cut-off table featured in ShopNotes Issue #27. Items are in no particular order.
After making the original design, I modified the table support
(item P) to be 10" wider than the table on each side. I found
only 6" either side (per plan) was not enough to support the
table to my satisfaction at the beginning of the cut. Since I
added the length, I also made the section 1-1/2" wide (two 3/4"
sections glued). This means the bolt lengths and stop position
changes from the plan.
Overall, I found it best to clamp parts together into final form
before marking for drill holes or assembling.
The plan suggests making the base plate, then the rear fence and
front rail, then assembling all three. After attaching the rear
fence to the base plate, I found no great way to locate the front
rail even with the rear fence. Thus I assembled the short base
plate to the rear fence (using the insert as a spacer), then
clamped in the (fully built) insert, which allows the front rail
to be lined up perfectly.
It may just be me, but I found the maple block that acts as a blade
cover at the end of the cut difficult to glue up (it's 5 pieces of
maple) without having the inside 3 pieces "squirt" all over the
place. Thus I made the parts oversized and then cut the final
block to size. I gave myself 1/2" to 3/4" to play with.
When gluing up the fence sections that take the toilet bolt for the
stop block, take great care not to get glue squeeze-out in the
channel where the toilet bolt rides -- it's a PITA to get out (but
use a bent coat hanger if you need to). As well, when gluing these
sections take care to make the bottom of the channel straight, not
the bottom edge or top edge of the fence. The top or bottom can be
jointed or sanded, the channel stays where it's glued!
The opening in the rear fence and front rail are shown basically
flush with the mating section of the insert per plan. I found this
gave the inserts a tendency to bind when lowered or raised. Thus
I made the mating insert sections about 1/8" narrower than plan.
This has no functional affect since they are bolted down during use.
