Offsetting Layered Signs

[larrycameron44]

I have plasma cut a Harley Logo Bar and Shield (not for sale of course ) and a backing plate (steel) that matches the outside diameter and want to have it in two layers, possibly with a 1/4 offset.
Can anybody shed some light on how I accomplish this without too much or a major job?

Cheers for any info

I do the offset ones 2 ways
1. For a small offset ie 8mm I tap 20 x 8mm flat bar at 20mm centres (5/16" x 3/4" @ 3/4 " centres) and then cut them into pieces to weld to the back of the front pieces (I find this works better than welding nuts) usually with a 1/4" unc thread.
To mark where to weld them, I first lay the piece on the backing and mark a few mounting points where the tapped block is not going to be visible from the front. I then drill the backing piece only, and then use this to mark the back of the front piece with the drill. You can then sight through the threaded block to the drill mark to check positioning, clamp (if possible) and weld.
2. If I want a larger offset the method is basically the same except I weld a bolt by it's head instead of the threaded block and use ERW tube spacers cut to the required length to space layers.

Hope I've explained it in an understandable way.

I'll try and take a few pictures.

This is a small stand off sign I use as a display sign done by welding bolts on the back (and yes I normally get about 1 a week that says "but I want my name not your name" )


and here you can see where the bolt is welded to the front and the second layer is secured with the first nut and then the backing is secured with the second nut.

Thank you very much for that info Muzza. I shall try that out. Cheers

For a larger standoff from the back plate I use 1/4 inch threaded couplers for linking threaded rod. you can get them in a couple of different lengths
I like the 3/4, and 1-1/2 for larger standoff( or just a nut for really small standoff

Thanks Brian, good idea too.

Cut some rubber oil line into 3/8" or 1/2" pieces. Then use them as spacers between your parts. Put your bolts through the chunks of hose. Cheap, Easy, adjustable and no rust.

Thanks hdfaster, not a bad idea as well. Very talented people on this site
