Joining MDF end to end

Postby bobbyraz49 » Fri Dec 08, 2017 4:28 pm

I'd like ideas on how to join one end of a MDF to another when neither are attached to a table. Am considering elevated sections to a possible new MDF track in my home.
Also...what do you use for a platform ?
Please inform me of how you do it.
Also, I see a few tracks that use copper tape and was wondering if there is a particular brand/width,thickness that is best.


Many thanks....Bob

Maybe?

Platform. Perhaps the table?

2 x 4 is strong and will last.

Under the joint is another piece of MDF about 4 inches wide, and the track surfaces are screwed onto that, with the joint in the center of the 4" width.

I've seen a lot of tracks over the years, joined with plates, tenons, dowels, all kinds of stuff. The examples here are the best there is. MDF can split unexpectedly when you don't think its stressed at all, so plates, tenons, dowels, etc just can't come out well, especially on an overhead.

From experience, I wish I would have never used wood glue. Some day you may want to take the track down or change it and to me, glue just ruined it. This statement was only based on my personal experience. Using scabs and deck screws alone will work and just fill in the counter sunk holes with spackling, easy to remove later.
