On my Mk 2 that is almost the same but 50mm shorter than the Mk 3, I have used black wood screws since I fitted it, about a year ago. It has nowhere near the depth of plywood that Stevie has incorporated into the Mk3. Interms of weight, I originally had the Beyma driver installed and that is close to 2Kg heavier than the Faital pro so I have no qualms about using wood screws. I have now done some calcs. and the 5mm dia 30mm length screws can hold up to 61Kg each into Poplar. Plywood is denser than its donor species so even with the four screws that’s hold the handle on, you have in-excess of 200Kg withdrawal force. I am not sure that the other 4 screws do much except ensure and airtight seal but I don’t have any qualms about using wood screws. I fact there is no reason why you could not use wood screws for the 12” driver although I would stick with some sort of insert or T nut. I used rivnuts designed for metal as I had some to hand.

Yes I did that first but found it a bit of a fiddle, I got adhesive and wadding stuck to my fingers. So I cut the ones above to size. I may cover the other braces behind the woofer but I suspect it will have little effect. I have been away all week so no more progress yet.

You added the reference to the KiOgan loom adding it completed the perfect P bass. I assumed from your previous mention of the sound of the pickup that you felt the loom added to the sound. Re-reading it I realise that I could have misconstrued your post. I hope you will accept my apology. I am an Electronics Engineer and hate it when people attribute magic to this or that component and clearly have a hair trigger when I see this. In this case I was wrong.

That different parts have an affect on the sound. There will be some tolerance (most pots and caps are +/- 20%). I thought you were implying that the rand of pot or cap influenced the sound. If you did not, I apologise.

I have not used those, I use the Sommer HiCon. Although a different shape, they look to be similar quality. The hicons are black though. I have just noticed that these are for cable if a maximum diameter of 4.6mm maximum outside diameter. That rules out the majority of guitar cables.

I have said that his work is first class from what I have seen. I would be proud to have one of his control plates on I any passive bass of mine. Yes pots and caps do affect the tone, BUT it is the value not the brand that matters. CTS pots sound no different to Bourns, Alpha, Piher or any unbranded pot, as long as they are the same value and same law or taper. Similarly , a cap is a cap. Orange drop or oil filled paper are not magic in fact some of the older caps fitted to guitars and basses drift with time. It is the value that matters. Quality pots will last longer and, alongside the quality of KiOrgan’x workmanship, that is what you are paying for. Once again my posts do not criticise KiOrgan in any way but all the magic he imparts is down to his skill, there is no magic other than reliability in the components.

The only real valve/tube replacement is Korb’s Nutube.

Yes I did read your post but manufacturers change pups during production runs. Also some pickups are low impedance, some are high impedance, so m I are designed specifically for use with pre amp and do not work well passively. The only thing I can say is that you will not damage the pups running them passively.

I can’t say as I don’t know what pups they’re fitted with.

No disrespect to @KiOgon but the wiring will have little effect on the sound. His pre-wired systems are very neat and easy to install but to claim anything else is misleading.

Sounds like pickup height to me too. Adjust for string balance not a fixed distance to the strings,

The recent reviews of the Halfords etch primer suggests it is smooth, My progress is slow, I am now away until Friday and then busy all day Saturday and Sunday. Good news is that I got some Supernova colour (black) paint in a tester pot from Wilkinson at £1.25. More than enough to paint the baffle. I was so excited that I painted it immediately, forgetting that I had not put the grill support battens in yet! The picture shows the baffle with two coats of paint and I have enough paint left for two more. I have also stuck the wadding in the lower half of the cabinet, I will do the remainder once I have installed the wiring onto crossover. The wadding may look different to the other cabinets as I am using the remainder of the wadding left over from the MK2 build that I currently gig. It is much messier than the one specified but I am convinced ( I.e. hoping) that it is as good or better. Ironically now the cabinet is fully glued up, it is much squarer than I expected when I found the bow in one side. So Banaba cab is now cucumber cab.

You make sure that primer on the skirting is good and dry before you put the top coat on 😂. Another tip, put the port in the freezer before fitting. It will contract and go in the hole easily. Then, as it rises to room temp, it will expand to fit the hole tightly.

You don’t have to write off the Celestion but It will not go so loud as modelled and (unless I entered some parameters wrong) has more bass extension than the Beyma. This was the thing Phil was trying to design out. However it will not take as much power and will only get to about 113-114dB. The Beymas will get to 120dB+. So I would build with the Celestion as the others should slot straight in if you want to upgrade at a later date.

I routed the hole for the handle on my MK2 cab and regretted it. It just does not look right. Yes I routed the recess slightly too wide but as mentioned, the round over on the handle looks better when the handle is mounted on top in my opinion.

Based on Phil's cabinet the BL-12-200X will work but it will be limited in output. I have modeled the following speakers Celestion BL12-200X Beyma SM212 Fane 12-300 Beyma 12CMV2 Of these the "league table" is as follows: Beyma SM212 Beyma 12CMV Fane Sovereign 12-300 Celestion BL12-200X In terms of cost, lowest first as of 13th October 2019 BL12-200X (not sure what you paid for it) Beyma 12CVM2. £44.34 (£50.40 inc delivery) - Blue Aran Jam Club £49.30 inc Fane Sovereign 12-300 £69.88, free delivery - Blue Aran Jam Club £65.69 inc Beyma SM212 £86.21 (£90.31 inc delivery) - Blue Aran JAM Club £88.15 inc To sum up, if you had to buy a speaker for the cabinet, I would choose the Beyma 12CVM2. It is close to the performance of the SM212 but a lot cheaper. If anyone wants to see the plots, I will post them.

No that looks like the correct bowl but the handle is wrong.

I think you are right about the glue. A really good coating and using the rubber mallet (if you have not got one you should have) or a hammer with a sacrificial piece of wood, Gently tap from the centre to the ends to ensure the joint is well seated all the way along. This encourages any surplus adhesive to squeeze out at the ends rather than pooling midway along the joint. Then use the clamps. I used two, one at each end and one through the woofer hole. I should have used more at least one at each joint (4). I suggest this way as I am sure this was where I went wrong. Finally check that there is a perfect 90 degree angle between the two pieces. One other point. It should be OK to screw the top/bottom at each corner, if required until the glue sets. Make sure the carcass is fully dry before drilling or driving the screws home. The metal corners will hide any cosmetic imperfections after the hole is filled. Firstly drill a pilot hole through the top/ bottom into the corner of the carcass. I use a 2/2.5mm drill for that. Then a clearance hole through the top/bottom only, 4mm. Do not use a countersunk screw . Of course if you have too many clamps.....*. Once the glue has dried you can either counterbore the hole driving the screw below the surface then fill the hole, or just fill the hole. I will post pictures early next week. * There is no such thing as too many clamps or too many basses (he said as he bid on a fiver).

I am sure Phil would answer soon enough but there are few 12” speakers at a reasonable price that would work well in a 30 litre cabinet. However, if you can wait a few hours I will model it for you.

Hot Covers is the other main maker.

Yes fall of or fall away is a good idea.

A good place to start is by using the Fender setup document. Of course some of the settings are “to taste’ but it is a good starting point.

They were just short of £1000 rrp here. I got mine via a personal import from Japan. Cost just under £500 inc insurance and shipping. Add £70 import duty and Igot a bargain.

Does anyone plan on building 2?
