Thread: Holding templates in place

Try Tesa double sided masking tape.

Glen.

If your template is MDF you could spot glue it with PVA in a few places with toilet or tissue paper between the template and workpiece as well . This will allow you to more easily separate the template from the workpiece but you will probably destroy the template in the process of removing it .

Try hot melt glue and seperate by cutting through the glue with thin wire, similar to fuse wire. The glue should 'roll' up by rubbing with your fingers. Sand well to remove any residue left on the panel...

Coming right out of left field here - been thinking about this a wee bit - may work...
A vacuum box for holding your work.
A tray say 600 x 450 x 50mm with pegboard as the top supported inside to stop collapsing on you, ported to your shopvac.
This will produce almost 14 pound per square inch on your worksurface.
Mask off the unused holes with plastic sheet like business file covers - or similar.
2nd use could be as a sanding box??

You should achieve more pressure than that Sandy, normal atmospheric pressure is in the reigon of 14 psi so depending on the vac suction you will have that plus some.....a good holding power for sure.

Sorry - 14.7lbs sq in is the max you can expect.
We are working Vacuum here
Thats why neumatics is so good.

Routing in a vac box is a great thing however as you rout the vacume strength lessens greatly.
I use a vac box all the time but I use other fixing methods to secure the template the vac box is primarily for dust extraction.

Perhaps another solution is to break the template into two parts.
using the outside of the blank secured by cleats for the first pass the shaped plugs that lock into some of the routs you have made in the first pass to secure the second template.

On the matter of DS tape scotch VHB is great stuff but don't go overboard with it or you won't get it apart.

VHB? Is that a brand name, or an abbreviation? :confused:

I sometimes even use brads just to hold a template to the workpiece... as long as the marks can be easily filled and will not be in a prominent visible position... works well and no movement. It might not be suitable for your task, but it is another option nonetheless.

There are some spray-on contact adhesives that have the prperties you need. If you spray only one piece the joint can be broken, if you spray both pieces the joint is permanent.

Brand is, uh , hang on (goes out to shed)

"Fuller Spray Bond"

VHB is a Scotch brand DS tape that you can only get from specialist tape suppliers. They usually cut a roll to width.
I use it for sticking things to forklifts.
Last time I bought some it was nearly $300 for a roll 40mm wide and about 300mm diameter.
Its quite storng and if you want to remove it lift it slowly and it lets go a bit then lift a bit more.

VHB = very high bond
Is intended as the sole fastening method for various non pourous panels
Can be purchased off the shelf from lincon sentry.
