Looks good!
It is hard for me visualize the end result. I might print on paper to get the feel of it.
If your printer can accurately do 1:1, this is a very good idea. I've done this with every amp I have custom faceplates created for. And I have not yet got the drawing right the first (or second, or third) time. This works well for both lining things up to match existing holes and punching new ones. I use a little bit of spray glue from a craft store to tack the paper onto the chassis before drilling. The paper is easily removed with those spray glue removes (like glue b gone, etc).

Thanks for tip Mike!

From the picture I see that your build is moving along quite nicely!

I will be away for a week but I will print on paper the faceplate as soon as I come back and report how the font and overall layout looks in real dimensions.

Need some advice on how to fix the chassis to the head cab I will build.
I am balancing between the Aligning Weld Nuts, and the No-Slip Clip-on Hex Nuts.
https://www.mcmaster.com/#cage-nuts/=12v7qoq

The chassis will be using Aluminum 12 gage.
I made a lip (3/4 of an inch) on my drawing (chassis plan)
- I could drill and attach the weld nuts (requiring 3 holes I am assuming : 2 fo the nuts and 1 for the screw that will hold the chassis inside the box)
or
- I use Clip-On Hex nuts and only need 1 hole per clip.

I dont know if the clips are big/strong enough to hold the weight of the whole chassis.

Which ones would you recommend?

Thanks.

Fred.

riv nuts that compress on to the lip are good. I always put a rail of battening for the amp to rest on so the chassis nuts aren't taking the full weight but are really stopping it moving backwards or forwards.


or put cage nuts in the actual bottom of the chassis and use long bolts fender style.

Thanks Marcus for the feedback.

I thought of an extra piece of wood to have the chassis stand on it, but did not see it on the many headshell for sale on the net. So I had discarded that option. This will definitely be part of my build now ;)

Cage nuts does not seem very easy to do if one uses the side of the chassis to mount stuff in it..

Always good to learn from other's experiences!

if you know before hand you're going to use cage nut's you just position your boards etc so there's room.


The JM sig/Wonderland 100w I built this year used that method.

Back on the project. I have received my new chassis. I have drawn the front and back faceplates. I am now looking for a place to have these plates printed and cut.
I checked mojotone' s service offering.

Looks like people had mixed feelings on the quality of the production. Has anyone worked with them on the forum before?
Would you recommend other places? It is quite hard to find on the web..

I live in Canada, and could ordre from the US.

I want to print on a thin aluminium sheet.
Silver front and back plates with black lettering

My fallback could be plastic.

Thanks.

Fred.

I have been very happy with the faceplates Sandy at precision design has made for my projects.

http://www.precisiondesignin.com/

The website may not describe all the options available. I know it mentions metal on one page. And she has been able to laser etch maple for one of my amps.

I've used Mojotone faceplate services with no problems but it was their files for their Bassman AB763 type I just wanted holes deleted and some relabelled so easy for them.

I have also used http://bnplasers.com/ with great results with files from my friend Dave (colossal). BUT THEY CLOSED SHOP it appears.

I think the most problem is sizing or scaling from what I've heard about faceplate provider problems.

It appears these guys (amplates.com) have stopped producing as stated on their website.

Yup it seems that setting up the file is the trouble. I might give a call to these shops because I spent a lot of time drawing everything at 1/1 scale. I would like to take all their requirements so I can provide a good layout file so they have a minimal setup work.

Thanks for all the info guys!

I still use indcom.graphics for my plastic faceplates, and they do metal also. Great guys, cheap prices for one-offs. I just create my drawings in Illustrator and export as EPS, and they do the rest. You can see at least five examples of their work on my amps for sale: https://reverb.com/shop/superconductormusic
