They will look very nice, I can't wait to see them set up in room.
I'd be willing to bet your next pair will be a little smaller and a lot quicker.

No regrets

Thanks,

 

Yes I pick up a cheap gun and just went with a friend's advise and online recommendation.

Over all I am happy with the HVLP gun.

 

Still not in the clear so I am keeping my finger crossed since I have never done any wood working that need any finish before.

For now the magic will be in the hands of the sanding and buffing.

 

But trust me I have learned a lot and will do things different next time.

Very Nice! Can you give us particulars? Measurements, specs (internal wiring) and descriptions of the sound. Wow.

2 words = More Lacquer!!!!!!!!!

 

New to this but, after sanding and buffing out for a mirror shine I found out 4 coats is not enough.

I see too much grain not filled, I will try to fill with additional coats.

 

I have read other projects which have sprayed about 10-14 coats to have enough to sand and are left

 

a with great finish.

 

So back to spraying and sanding I go!!!!!!!!!

It would be interesting to see how much the lacquer adds to the weight of each tower once completed. On a cabinet that size it could probably add, what.. 10 lbs per?
Did you happen to weigh them before applying the first coat?

No regrets

That is a very good guess I am sure I have added 8 -10lbs easy.

I am not sure it is too large to get them weighed but I will take to my friend show he has a large scale.

He said I could use it to get a actual weight per tower. <should be fun once I get to that point>

Well it is Friday

 

More wet sanding tonight to see if I need any additional coats, stay tune.

We are so close just hate to cut corners now  and skip these minor step which will show up big time at the end if I don't do them now.

 

Here we go!

Piece by piece, one at time.

 

Sanding the finish is longer than expected to dry, it was not completely hardened yet, I believe due to cold temperatures.

On the second day it was just not sanding or buffing out well but by the third day I started to got better results.

 

I moved on to other thing just to kill some time.

 

Hope to have it finished by the end of this month? <hope>

Waiting on the lacquer to harden / cure.
Before I wet sand it again.

The original plan is to have all drivers sectioned off by size and yes the i am working on the upper min range which i know wont need that large volume.
I have thought about having cut out for free movement but not sure if it would be better or worst?

And I do understand now the tweeter position level now.
But for this set up it is too late i could redo the front face and experiment it further.

Also the x-over topic is confusing, i know i am using cheap ones the is clear. I will plan a better set up design on my next project including better drivers.

I just wanted to see if i could do it.
Trust me I am wishing for the best just did not want to scrap it at this piont.

Here is where i am at now

I cut out the holes on a double 3/4 MDF facing & started to work on the trim rings.

.

I like your project, excellent wood working skills. How did you make the trim rings and what is the material used for them Thanks sawz.

The trim ring are made from 3/4 MDF scrap wood left over when possible.
All hand crafted on the router for the inner angle bevel.
Then I sand it smooth / cover it with vinyl spackling / then they are ready for paint.
I will try to take picture while i am doing the larger ring this week.

They are the my last step of this project since I am trying keep the dust down while I spray lacquer.

So you made the rings with your circle jig, then rabbet the the outer edge of the inner side facing the driver so the ring fits snug and just about touches the installed speaker, then switch over to the 45 degree bit for the inner angle side facing outward. Now when you install the ring does it make it to where you can not remove the driver unless you remove the ring and if so then how will you install/fasten the trim ring?

Sawalot your Correct!

 

The ring are designed to fit very snug, and stay in place on their own. They are very difficult to remove by hand.

I think it will be best for me to make my own tool (bent flat screw driver) to help make removing the ring easier in the future in case I need to change out the woofers.

 

I am just going to get a cheap screwdriver and bend it 90 degrees with about 3/4 inch left over on the tip.

The small hooks tool could slip and scratch the ring, but I am sure you get the picture.

 

Example pic below are not mine. (just for ideas)

I just found this thread but I gotta say I admire your desire and skills to do this. It'll be a great learning experience for sure. I'm looking forward to your completed project and your final thoughts once up and running. Bravo!

Huston we have music! eek.gifcool.gifbiggrin.gif

Tonight I did 90% of the wiring for tower #2.
Sounded great but I could not turn it up because of the time it is now (almost 2am)
It is still in the garage laying on it's back. Cant wait to listen to it tomorrow even if it is only one tower for starters.
Still have to finish the rings which are not in the picture yet.

You can now get an idea of how it is going to look like. (Almost done with one)

Awesome. One of the best looking diy speakers I have ever seen. Definitely better than any speaker I have built. You took a big risk on this design that you throw together and I hope you can make it sound as good as it looks. Great job so far and good luck.

That is a concern of many speaker builders here, the ultimate measurable performance of these twin towers. Not that anyone else matters , in retrospect the onus lies solely on the OP to tune them in for his needs in his HT.
If he loves them thats all that matters !
