Hi SB

Pickup a Ruler one of the 6ft or 4ft ones, or 8ft one they come in handy for plywood and the price is right for them...and they should be true...

There is definitely a skill involved in using contact cement.
One I certainly have not mastered.
I still use it for laminating Formica onto countertops ---
But for most anything else --- I have fallen in love with TitebondIII.

Hi Cowboy

I also like Titebond glues the only thing I don't like about the number #3 is the price...
It's bit over kill if the project is going to be inside all the time.. if the MDF gets wet that's ,it's firewood... LOL like many of the man made woods/boards/plywoods..

Agreed on both points - but there are things it is ideal for -- and I don't like having to pick and choose -- so I just buy a big a bottle of III as I can find to help offset the cost.
If I am out of glue and need something for inside only -- I usually grab good old Elmers Carpenters wood glue.

If it actually gets WET I'm not so sure it's even good for that -
Maybe kindling -- I thought your earier comparison to cardboard was superb.

ALTHOUGH - to give it credit ---
I threw myself a desk together once -- with an MDF to --- and didn't get around to painting it for about 2 years.
It had set there raw all that time with coffee cups and hand oil etc -- and was still in decent enough shape I was able to prime and paint and keep using it.

The trick in using Contact cement for me is using either thick waxed wrapping paper or cardboard in between the two boards. Let the contact cement get almost dry then pulling the paper or cardboard out. I also used two 24" x 38" pieces of MDF. But I screwed them together. Thinking that if the top piece went bad from dents and stuff - I could just unscrew it and replace it. I pre-drilled the holes - screwed it together - then unscrew them and used a scraper to remove anything that had lifted up. Then screwed it back together. Seemed to work good for me. I was afraid to use a water based glue not knowing if it would swell the MFD.

Once the glue cures, pull out the screws. They aren't going to be doing anything anymore

Thanks for all the input. Bob mentioned rulers/straight edges. I live in a rural area. Where is the best place to get one?

I don't need one that quick but thanks for the advise.

I have used contact adhesives before for plastic laminate. I used dowels to hold the two surfaces apart until the minute of truth.

I think with the MDF, that I would simple make it oversize and then cut it to the dimensions I seek (using contact adhesives)

thanks
