Lams from Fedora's arrived. Between Kenny and Jason, there is enough for a few prods. Kenny, if you are out there, I hope that knee is ok.

Got the old direct drive 10" table saw on line. Cut up some new riser block out of Canary. Better grain for routing.
Keith has the riser jigs back and is making one-piece steel clamps to replace the two mill clamps on the first test.

Image

Finishing up the form. Adding cam washers with threaded inserts and knobs made from knob caps pressed onto socket head cap screws. Taking care that the washers in the form middle do not cover the centerline.

Image

I think I will cut the hose down next.

Hope to glue this weekend.

Worried about the riser moving while doing the straping tape step after glue-up. Added a "third hand clamp" like I use on my bows. Note: remove after taping lams to form.

Kirk,
Linear distance from black line to black line is 42". Same as the lams. Are we looking at 44"??? Will this give clearance for the cord without exposed unsupported strip?

Yup.... I'd say a 44" strip will be great.... the only thing i would recommend is adding a couple lam scraps where I've shown in yellow, and just tape them to your hose after air up.

that is the place where you have to be careful with these heaters and insulate them without pinching them with the hose..... you need to round over the edges on your pressure strips too and try and keep the heat strips straight rather than let them hang down.

What width are we talking about here bro?


Btw.... be sure and pull those zip strips out before you get too much air pressure. i go about 15 pounds and let her set a minute, then pull them.... i screwed up a set of limbs forgetting that one time. :roll: i had perfect zip tie lines in my limbs melted into the glass. :shock: :shock: :shock:

The zip ties are temporary. After strapping the lams to the form with strapping tape, they are removed. Width is 1 3/4".

This is still a dry fit. The hose in the picture is now cut down.
