Thanks God for craigslist.

Most people use hot glue although I have thought about using a vacuum pump on my profiler as well. Very curious to see how it works out, post some pictures when your done.
Air volume is more important than the effective vacuum.
thats the way you go.
i m using a mdf board with some air-channels. a festo vacuum cleaner attached, holds the cores that you need force to pull them of.
i started with a cheap vac cleaner, that sucked the air through 2 holes in the router table. now, with the stronger festo cleaner i have 3 holes along the core, results in a constant holding force.

this is exactly the reason I went with vacuum pump also in several tests hot glue suddenly broke off. Not to mention vibration between glued point.
I'm going to make profiler table inserts like this one http://www.skibuilders.com/phpBB2/viewt ... c&start=15
my "new to me" pump powerful enough to hold core in place. Will need to figure out simple vacuum system. Probably small tank, valve and filter. Appreciate suggestions here
I didn't know shop-vac can be used. I don't have shop-vac big enough anyway and this pump cost me less than good size new shop vacuum.
my original intention was to build simple yet accurate profiling jig. I went from wood to strut channel to U-channel and every time bent, kink or twist make a whole set up inaccurate.
after some thinking I decided to build this design
this project take much longer than I ever thought.
Finally progress!!!!!!!!!!!!!!!!
While waiting for few parts to be welded for profiling table I made overhead router attachment to table saw. Some more work will needs to be done to it like attach dust collection maybe add pin so I don't have to use bearings on router bits for templates.

I have the problems with snocad's printout templates. Print same PDF file three times today and every time dimensions slightly different from what it should be. One template 20--30mm shorter and T/W/T approximately 10 mm narrower . Second template overall length 175 instead of 170 T/W/T also slightly off not as much as other one about 5 mm. Third one I print only half same story.
Also pages do not line up to well
connected pages came out good but different from what I wanted to.
What I'm doing wrong? Is it normal in snocad to change dimensions after printout? what can I do to fix the problem?
Make sure your print program has the scaling right.
Or
Take it to a shop that does large format printing and have them print a full scale print out for you. Much easier this way. Only cost a few bucks to do it this way.

I think scale set correctly. Now I am only doing a trial/learning template making and dimension not as important. Considered printing full template in Kinko's shop.
I simply was surprised to get printout different every time
Did trial template making today, came out nice and smooth. A few more times small-scale template making so I can get better on doing it and I'll be ready to make real stuff
