Many of you have inquired about my new scale cam lock adjustable straps (available for sale here,http://crawlcanada.com/forum/showthread.php?t=11173 ) so I thought I would show you guys the steps that Scale Innovations takes to make one of these nifty little items. :biggthumpup::rock:

http://inlinethumb60.webshots.com/44667/2578220640032635288S600x600Q85.jpg

part 1: Layout and cutting.

We start by cutting 2 squares, part A is slightly wider than part B. Then scribe the lines for the bend points.

Find the center points for the hinge and center punch.

http://inlinethumb25.webshots.com/46168/2682277640032635288S600x600Q85.jpg

Drill holes for hinge pin.

http://inlinethumb14.webshots.com/45709/2413142490032635288S600x600Q85.jpg

Trim the edges of the plates.

http://inlinethumb26.webshots.com/38553/2829329010032635288S600x600Q85.jpg

Letter punch the Scale Innovations "S".

Part 2: Bending and fitting.

Place the parts in the metal brake and line up the bend lines.

http://inlinethumb18.webshots.com/23441/2409534750032635288S600x600Q85.jpg

Bend 90 degrees.

http://inlinethumb62.webshots.com/38461/2655558670032635288S600x600Q85.jpg

Place the parts in the metal brake and line up the bend lines for the 2nd bend.

http://inlinethumb34.webshots.com/47841/2239722120032635288S600x600Q85.jpg

Bend 90 degrees.

http://inlinethumb22.webshots.com/41045/2363866940032635288S600x600Q85.jpg

http://inlinethumb59.webshots.com/39610/2809258510032635288S600x600Q85.jpg

The two halves are checked for fit then procede to final fitting.

Continued:

The hinge hole is checked for alignment and adjusted if required.

http://inlinethumb25.webshots.com/3224/2948684560032635288S600x600Q85.jpg

Hinge pin is temporarily installed.

http://inlinethumb49.webshots.com/47664/2501920180032635288S600x600Q85.jpg

Now a section of the smaller halve is removed to create the "cam"

http://inlinethumb63.webshots.com/30718/2454168410032635288S600x600Q85.jpg

http://inlinethumb34.webshots.com/47137/2260257460032635288S600x600Q85.jpg

Testing the "cam" Here you can see when open there is a tiny gap.

http://inlinethumb41.webshots.com/46696/2701466700032635288S600x600Q85.jpg

And here in the closed position with the cams locked.

http://inlinethumb07.webshots.com/32326/2893843830032635288S600x600Q85.jpg

Mounted in a vise, the strap slots are cut into the large halve with a cutting wheel.

http://inlinethumb29.webshots.com/44764/2911112540032635288S600x600Q85.jpg

Debur both halves, check for proper slot / cam orientation.

http://inlinethumb58.webshots.com/43769/2468843810032635288S600x600Q85.jpg

http://inlinethumb43.webshots.com/45418/2691907220032635288S600x600Q85.jpg

The parts get polished or painted.

Next up! Sewing the straps.

Part 3: Sewing.

First we sew one end of the short strap to a hook and sew the hinge pin loop on the other end.

http://inlinethumb26.webshots.com/45721/2289957510032635288S600x600Q85.jpg

Sew another hook onto one end of the long strap and fish the other end thru the bottom clamp.

http://inlinethumb22.webshots.com/47189/2870823720032635288S600x600Q85.jpg

Install the top part of the clamp and insert the hinge pin loop into clamp, install hinge pin.

http://inlinethumb38.webshots.com/47781/2371532970032635288S600x600Q85.jpg

Sew the other end of the long strap so it will not pull thru the clamp.

http://inlinethumb06.webshots.com/45189/2468990490032635288S600x600Q85.jpg

Trim and peen the hinge pin.

http://inlinethumb54.webshots.com/24181/2145293620032635288S600x600Q85.jpg

Done!

http://inlinethumb60.webshots.com/44667/2578220640032635288S600x600Q85.jpg

So thats how it's made, shure takes a long time an a lot of work but worth the effort in the end.

Those turned out great,may have to pickup a set.If I could offer a bit of advice,pick up a sewing machine and cut down on production time with hand stitching,I use(or should I say my wife)a sewing maching for all my straps etc and saves time which means you can make more.Great product....:biggthumpup:



Thanks, I tried a machine but had trouble keeping the strap from getting sucked into it. prob be ok if I made larger loops, but then they don't look as good. I will have to consult my seamstress for some advise. :biggthumpup::rock: Would be nice to not spend an hour each sewing.:bugeyes:

the only way to do it with a machine is to make the loop back longer the cut off the extra maybe a drop of ca to stop the fraying

or ca it first then sew it

Good Idea, didn't know they made those toggles that small, might have to look into that. :biggthumpup:
