Dana's DR250 Adventure

thanks Robin.
Here's a wiring question: If I have a 50' length of 12 gauge speaker cable but the terminals from the jacks to the crossover are 16 gauge (3 or 4 inches), is my resistance limited to the 16 gauge or is the short length of it insignificant?

No. 16ga is fine for that short of a run. The 12 gauge handles the longer run.

Thanks Bruce. You're becoming quite an asset to this group. Our setups are very similar too - less OTops for me but, DR250s on the way. If I ever make it to TX I'll be sure to look you up.

That's mighty nice of you to say. And rest assured....if I don't the answer - I'll make something up.

Long shot here:
But, does anyone have any PRE March 2012 throat fillers for a DR250. Or, any material to make one or more??? I can't find any 1" rigid foam in anything less than 4'X8' sheets

Have you tried Hobby Lobby?

Or, that green stuff that florists use?

[ripNdeb]

I'll check the florists. Is that stuff closed cell? It needs to be closed cell, correct?

[biggerrigger]

I could not find 1" either so I made it! I took 1/2" foil faced ridged closed cell foam and pealed the foil face off of both sides. After I had two peices peeled I used 3M Super77 spray glue and laminated two pieces together. After they setup overnight I cut them to the dimensions in the plans and used them as directed.

I think so. I'll check.

[ripNdeb]

I found some Styrofoam that might work but will be extremely messy to work with. Any luck on your end Leland?

Never mind....I found some!

[LelandCrooks]

Good. I looked pretty hard yesterday and don't have any.

Almost time to finish up this thread.

Here's the cab back ready for some kind of finish that I mulled over for a long long time. Next to it is a simple 12U rack I threw together. for Sketchup PM me.


Another shot of the same showing the end/back joining filler whatever pieces curing.


And the long filler piece to complete the back except for trimming, sanding, painting, etc.


And now, for the solution - a 1-1/2" strip, followed by a 3/4" strip (not shown). Filled it with Bondo and rounded the whole corner:
