Vibramute tremelo plate manufacture

Postby Bushers » Mon Oct 05, 2009 7:27 am

Ok, some time ago Dantana asked me to help him out in drilling the holes and finishing his cast Vibramute tremelo plate, he was going to post some pics but must have been waylaid with something else so thought I'd share what I did so if others buy a cast plate they might be able to replicate what I did (if you have access to some proper tooling!)

Firstly, I marked out the location of the hole centres using a Vernier height gauge.

Then I clamped the plate to a faceplate ready to drill the two main holes that house the bearings, (needed to make sure that these holes were perpendicular to the 2 forward bridge holes that I drilled after);

Image

Then it's back to the bench to drill and tap the bridge post holes;

I also opened out the mount hole locations, this was just a simple task of letting the drill find the centre of the countersink in the casting and drilling through using a pillar drill.

We decided to go with the polished look and although I didnt have a great deal of time to spend on this, it came out pretty good. I firstly smoothed off the entire surface then gradually stepped down grades of sandpaper before I went to a coarse polishing paste down to fine to finish. After the polishing, I masked the area to be sprayed and painted with a base primer then a matt black to achieve this finish;

Then, finally, went over the tops of the letterings to get the final result:

I did go over the countersinks after this shot so that they were simular in size as the casting was pretty rough! I think once assembled this would have looked pretty sweet, though I would have liked to have spent more time polishing out some scratches, it's a long arduous process if you havent got the right tools though!!!

Great pictures, Bushers. If you don't mind me asking could you give a list of the tools you used? I may want to make my own Vibramute bridge some day ;)

Very nice Jason! I just went through this process with an unfinished brass Vibramute, and the results are not so elegant - the bushing holes came out a larger than they should be and we nicked the plate between the holes. It sure helps having the right tools!

The polished look is nice - will you cover it in clear laquer? I wonder if it will tarnish otherwise.

I posted it back to Dantana without any lacquer applied, I applied a chemical conversion coating used in aerospace though that should stop corrosion and tarnishing (alodine 1200).

Haven't got the tap size for the bridge adjustment holes to hand right now but I used these tools;

Digital Height Gauge
Angle Plate (on the mill)
Surface table
Milling Machine
Pillar Drill
Centre drill
11/32" drill for bearing hole
5/32" drill for plate mount holes
coarse to fine sanding pads
metal polish with lint free cloth
