Hi Ruben, I applaud your efforts. Ken makes some very good points.
I often think of my bass fishing mentor who said to me "if you want to become good at the sport of bass-fishing and really enjoy it, then you have to get the right equipment"
One thing that I have learned listening to Ken, Arnold, and all those who have been successful in luthiery is that you have to have the right tools.
As I say, I commend you for your efforts. I have not been doing luthiery work all that many years, but I am probably one of the oldest OFs on this forum and know aspiration and passion when I see it. I want to encourage you to get the tools that you need that will help you do the work that will better match your desire to do good work.
As creative as the magnets are, they have not done the job, IMO. You can see in the first pictures that the cleats don't fit the surface of the bass top as they should.
I recommend that you stop everything, remove the cleats, get the right clamps and start all over. And, I recommend, as I did once before, that you seek help before you attempt anything. When you tell us what you are going to do, then we can tell you what tools you will need and will tell you how to do it. You have also received books that show you how to do repairs and the tools needed.
I have to be perfectly honest with you Ruben. You have, at your request, the help that you need. However, if there is one common error in your approach to luthiery that has once again surfaced, you are not paying enough attention to the guidance given you.
Yes, given what you have used to accomplish the cleating, they do look sorta good, but you can do better work and cleaner work. So, stop everything, get the right tools and step by step instruction and do it right- you'll be glad that you did.
The clamps that you need are expensive, but you can make some for just a few dollars.
Before you install the soundpost patch, it will be important that you get all the cracks repaired correctly. Also, if you plan to replace the bassbar, the top needs to be in good shape first to include a proper reshaping in most cases.
Ruben, what you are attempting to do here is work on an instrument that is usually done by an experienced bass luthier.
This is not to say that you can't do it, but an experienced bass luthier is going to have the tools and equipment before he/she will attempt this kind of work. Many of us have had to learn this the hard way. The hard way is what you are doing now and this is the reason I am asking you to stop everything, get the right tools and equipment and begin again.
An example for what I am trying to say- Why is it that good bass luthiers can repair a crack to where you can't see it? They get the result because they have the right tools and equipment. They, also, have listened to their mentor's instructions on how to do the repair correctly.
Ruben, Hope this helps. Good luck.
