Waz's MMB-4

[Simon Barden]

It's worth getting one with the flexible extension as it makes getting a burr or a sanding drum into a tight corner a lot easier. Also makes engraving-type tasks a lot easier as you can grip the end more like a pen.

I’m not usually one for product endorsement but I brought a Dremel and it’s my favourite toy at the moment. As an engraving tool it is 100% better than the engraving pen I was previously using.

I'd be concerned about the longevity. I had the hobby re-chargeable Dremel that sat in a charging cradle when unused.
Got about 12 months when it carked it.

So I got myself one of these. https://ozito.com.au/products/rotary...0w-42-pce-kit/

3 years (at least) with several guitar projects and it's still going strong.

cheers, Mark.

Wired up the DPDT mini switch earlier tonight and that works & sounds best out of all the combinations tried so far.

Thanks guys for all your ideas, guidance & assistance.

Next job is to dig a bit more timber out in the control plate cavity as there is a square plastic terminal block for belcat pre-amp with lots of wires coming and going that is preventing everything fitting in an already cramped space. Don't own a dremel and not keen spending the coin for just this one job. Might have to use a chisel instead unless someone has a bright idea for cutting/recessing at 90 degrees inside a 30mm wide trench which is just on 38mm deep?

For it it sit vertical, thickness is about 6 or 7mm thick whilst horizontally I would need to go about 18 to 20mm deep and drilling in via jack socket hole seems most logical way to go? Will ponder this for a few days before attacking it.

Waz,

I have a green shed brand dremel style tool....with a flexible extension....and heaps of fittings.

I am at work....residential care in a community home in Bells Reach.

I am supposed to finish sometime Friday.

I will be home over the weekend....either drop in and grind away...it is permanently setup on my desk....or come borrow the machine.

I only use the sanding attachments...no idea what the rest do. 😎

Thanks for the offer Ozzie. Never used one and not really sure what does what either but reckon between us we could figure something out?
I also have work getting in the way of having a life and only day off this week is Sunday. Will send you a SMS Saturday afternoon to see if still ok to catch up on Sunday.

Cheers, Waz

Caught up with Ozzie earlier today and had a good time having a chat, playing guitars, and also got around to digging out some timber in the control cavity of this build to help make the pre-amp and all it's wires fit down low enough for boomerang control plate to sit flush with body....

Thanks for helping me out yet again and loved how your MMB-5 build looks and it is coming along real good.

Cheers, Waz

You are most welcome. Thanks for bringing the coffee and pies.

I really enjoyed your five string that came along for the ride. Gave me a great insight as to what my mmb-5 will do. Thanks.

Just a query, and maybe weirdy or Simon may correct me...Your nylon bushes are keeping the pots from contacting the metal control cavity cover....and I cannot see a ground link wire running from the back of each pot to the next and then to the ground connector on your socket. Could this cause some of the issues you are having? Consider earthing everything...and it may also give you that noticeable difference between switch positions.

You are always welcome in my workshop. 🎸🎶🎼

G'day Ozzie, everything is earthed to the volume pot.
Stacked blend pot wasn't doing much on coil splits and as you heard with the dpdt mini switch there isn't much happening with one of them either, just more noticeable than using blend that came with the pre amp.

In addition to what Waz has said above, the threaded shaft of the pot is in contact with the metal control cover, also via the nut and washer keeping the pot on tight, the pot casings themselves will all be connected together and as it looks that Waz has got at least one ground connection to the back of a pot from the photos, so all should be well. But if you haven't done it yet, then it never does any harm though to double check the ground continuity with a multi-meter, just in case.

All is good. I hope you get the outcome you want.

(Thanks for the wetsanding advice 1200 levelled up nicely. Nice full strength coat over it and those little holes are gorrrnnnn.)

Thanks. 😎

Good to hear Ozzie.

Do you have any 1500 or 2000 as I have some spare if you need it.
