Jig for trimming plastic stackable corners?

[David Carter]

No PL, just screws. I'll second Bill's question... Why would you only have screws on one side on a Titan?

My guess is that the screws are used on the 'first side' to pull the panels flat onto the side until all the panels are in place and braces positioned, glued and nailed in.

Assuming the panels have been accurately cut for width, then strictly speaking now screws ( or brads ) may be required to attach the second side.

However my faith in how long PL will last over the years is little so therefore I strategically screw both sides and use brads in between the screws.

I don't think you need to sweat it. I know you had some adhesive problems with other brands in NZ. PL has been widely used here for a very long time in the construction industry, and OSI is a premiere supplier of specialty adhesives to industry. They're a big player.

One of us has completely misunderstood the question that was asked. It was probably me. Since he was talking about plastic corners, I thought he was saying that the plastic corner would only have screws on one side of it, and that the second side (of the plastic corner) would not. Didn't make any sense to me, so that's why I was asking a follow up question.

I just meant the plastic corners The cab construction is complete!

I'm just a little confused as to what to do with the arrangement of the corners, possibly due to me selecting recessed casters on a slim cab.

Picture one shows the horizontal configuration. Obviously a bad selection, less than half of the corner would remain.

Picture two shows vertical alignment. Can use the router to trim it flush and three screws would be used.

However, to match it on the opposite end (the bottom of the horn mouth) the majority of the corner would be cut off, leaving screws only on one side of the corner.

Oh friggin duh. After looking at the pictures, I just need to turn the corners so they are lengthwise along the bottom and top.

Need a brain fart smiley. Sorry ya'll.

Anton, IIRC you have a router. Use it, with a bottom bearing pattern following bit to trim off the excess. Finish the corner with a sharp knife.

To follow up on the Phatman's suggestion: that's what I did. I'll see if I can get a pic of the jig posted. Corners looking great on the O10.5

I don't think PL adheres at all on the plastic surface, so glueing where screws are not an option is not going to work.

You might also consider metal corners. I found I broke at least one PE plastic corner per gig. Leland says he has some better ones, but I switched to metal before he announced them so I haven't tried his.

Just following up on this one. I did indeed have to cut the corners in half - on the two bottom ones next to the wheels. Oh well.

They've been thrown in the back of the Tahoe a couple times and seem to be holding up with only two screws... so far.

I use the black DAP® DYNAFLEX 230® Premium Indoor/Outdoor Sealant Leland used to sell. Just enough to hold the corners to the cab.

[Spoon]

I sat my corners on, then ran a pencil on the inside lip (that hangs over.) Then just cut it off with tin snips.

[AntonZ]

Here's my little jig. I clamp it to the work bench, install a corner, then one carefull pass with router and top bearing router bit.







And here's a cut down corner, perfect fit on 12mm (1/2") ply and allows the access panel to be opened.


It's pretty easy and straight forward. Yet, if Leland were on my continent I'd get the smaller chevron corners from him.

You've painted them?

[AntonZ]

I painted the cab, black concrete floor paint. More of a dark grey actually. Not the corners though. Does it look like painted in the pic? It's a plain black plastic stackable corner.
