Cameron,
Here is how the hose on back build works for me.
I use a Rockler jig to cut the angles for the riser insert first.
same jig different angles cut out the belly section of the handle
handle and insert after cutting and a little grinding on te back of the insert only to perfect fades
Heres how they fit in the form. When I built the form I cut out a 24"x1.5" square on the belly of the handle. I made laminated oak blocks to fit against the handle on the same angle jig by matching the angles. this way I can change the riser insert anytime I want without building a new form.
Here is the form assembled.
notice the routered grooves with zip ties I use to hold the lams in place during glueup. The form is 2.24" wide and these are cut in to 1.5". the beauty of this form is there is no fitting the riser insert to the form and the overlays and tip overlays go on at the time of glueup. I get great glue lines every time too as there are no sweeping curves in the riser lams to worry about. It feels a like cheating as its so quick and easy.
