WayneK Posted February 20, 2017 Share Posted February 20, 2017 (edited) I presume the screws holding the inductors on the board are not steel. Steel will change the value of the inductor and probably do other things as well as the steel saturates with signal This comment relates to the air cored inductors only .

tvcollector Posted February 25, 2017 Author Share Posted February 25, 2017 So guys i need some help just finished the next crossover looks much better than the first so i tidyed up the first so they are uniform but ive been reading A guy upgraded his and used 50watt resisters does that make a difference as i dont have the original rating i used 5watt and 10wwatt is it better to go bigger? Is 50watt excuse my french but wank factor or does it make it better in some way cheers Link to comment Share on other sites More sharing options...
Guest atilsley Posted February 26, 2017 Share Posted February 26, 2017 Resistors can struggle if a lot of extra power going through them...which is why people double them up. If you're using, say, 300B valve amp, 50 watt resistor OK. Different if running massive bi-amp config.... Link to comment Share on other sites More sharing options...

tvcollector Posted March 8, 2017 Author Share Posted March 8, 2017 Getting closer have had a break from the cabinets and have been finishing the crossovers and testing and putting the finishing touches on the front panels for them going to look very nice pictures to come.

tvcollector Posted March 10, 2017 Author Share Posted March 10, 2017 So big night tonight veneered the sides in the front and cut out the peices for my curvs was hard to work out the angle but got there and happy my side joins worked out was a bit worried, the biggest and hardest part of this build is definitely the veneering i must say i wish i could have bought the timber veneered already like others do but because i had to glue all my sheets together id have to send it to someone after. But at least im learning a few new skills. 5 Link to comment Share on other sites More sharing options...

tvcollector Posted March 11, 2017 Author Share Posted March 11, 2017 Another big day and night measured the angles on the front and the plan was to use 3x sheets of 3mm which all up with veneer is 10mm so i came in 10mm from the top and in at the bottom then went to staple the first sheet well 3mm Doesnt bend like i thought. So tried to screw it down but it just kept splitting the timber so i gave up and had to make new peices then after procrastinating for an hour i came up with the idea of cutting it into heaps of strips and then i can make each peice fit properly yes probably the hardest way i could of done it but it is the most important part of these speakers So has to be perfect. I need to line up 4 sides of veneer spot on so once screwed in i filled the lines and cracks. 1 Link to comment Share on other sites More sharing options...
EV Cali Posted March 11, 2017 Share Posted March 11, 2017 (edited) So do you now intend to glue veneer over the shaped timber? There area couple of other ways you could have formed the shape but your way will work and that is all that matters.

Yes and its going to be a pain in the ass it isnt glued in yet that peice comes out so i can veneer it then fit it in and sand to get it perfect. Yes i know i had a look tonight on youtube should have done that first but i was in the mood to just get into it lol 1 Link to comment Share on other sites More sharing options...

I'm no expert by any means and couldn't tell you how to do it but hopefully someone here might have more of an idea about it. I am definitely enjoying reading about your project and the great work you're doing, can't wait to see the final speakers. Link to comment Share on other sites More sharing options...

kranky Posted March 11, 2017 Share Posted March 11, 2017 Toby, Have a look at Plymaster for bending ply it will bend over that profile with ease. But the way you have done it also work's to form a curve just a lot more work. Here's a pic of a horn speaker i built using the same method. Keep at it Great work. Steve.

EV Cali Posted March 11, 2017 Share Posted March 11, 2017 The problem with kerfing, cutting grooves across the ply, is that on close inspection flats can be seen on the curve. Another method is to glue several thin pieces together, clamped round a former. When dry they will retain the shape. Like the ply on an Eames Chair.

shaky Posted March 11, 2017 Share Posted March 11, 2017 As @kranky said bendy ply is your best bet for a decent and easy to finish solution for this application. Most board places will have it or be able to get it. Link to comment Share on other sites More sharing options...

shaky Posted March 12, 2017 Share Posted March 12, 2017 (edited) @tvcollector just to twist your arm a little maybe... thats 6mm bendy ply, would easily bend around 100mm diameter curve if not less given the right persuasion. Its great stuff. Edited March 12, 2017 by shaky 2 Link to comment Share on other sites More sharing options...
tvcollector Posted March 13, 2017 Author Share Posted March 13, 2017 Thats impressive you are twisting my arm will go see the bunker today, on another note got my front panels made They look impressive very happy now i just have to finish them and put them together without scratching them 4 Link to comment Share on other sites More sharing options...
tvcollector Posted March 14, 2017 Author Share Posted March 14, 2017 Tonights updates didnt get much done but got the top done decided just to do the same so it was all the same just a bit nicer. I procrastinated a bit to work out the next steps and how to do the veneer without gaps 2 Link to comment Share on other sites More sharing options...
EV Cali Posted March 14, 2017 Share Posted March 14, 2017 How are you getting the shape for the veneer? One way is with a scribing block . This was a method I was shown when I worked on fitting out boats, lots of curves with panels to fit against them. It is a method of obtaining the shape and then transferring to the veneer. In this case I would transfer it to thick card and then when the card was a perfect fit, on to the veneer. I can explain the method if you need me to . Looking great though.
