1st coat of Osmo Polyx Oil applied around speaker binding posts, though you would hardly know it, prior to assembly.



Ready to stick the other side felts.

i'm looking for help now.  My soldering skills are not good, but i have successfully built a couple of Genera phono stages.  How do i best set about attaching the internal speaker wire to the speaker binding posts?  I've been trying for a while and have, so far, been unsuccessful.  It's what i struggled with most when building the FH3s for the boy, but that time i managed.  i think i'm dealing withe thicker speaker cable this time.

I used Spatia wire, it's much thinner. For the thicker cable cut a few strands out so that you can thread it through the hole or make the hole bigger then solder. It will need a quite a bit of heat/time for the heavy brass part to get hot enough for the solder to flow. It's generally good practise to "tin" the parts first, ie apply a small amount of solder to coat each part before you bring them together, usually helps in getting the heat into the heavier part before you apply solder.

Just listen, if it sounds good to you, enjoy it.

Thanks Ian. I used Spatia wire for the FH3s, which is probably why i’m Finding this so much more difficult. I’m not sure my soldering iron is man enough for it.

I would think that it would need at least a good 25W iron with a heavy chisel style bit. An alternative might be to use a solder tag type washer. Much easier to solder and fit as they are secured to the post with an extra nut.
Perhaps a bit late to say this, but I use 4mm Instrument sockets on speakers and terminate my speaker cables with BFA 4mm BANANA PLUGS Z-type Gold Plated Cable Connectors https://www.ebay.co.uk/itm/4-BFA-4mm-BANANA-PLUGS-Z-type-Gold-Plated-Hollow-Speaker-Cable-Connectors/302480843779?hash=item466d436403:g:kVIAAMXQ01tRUKwW

I would carefully tease the stranded wire into two halves, twist and tin them separately.Tin the flat bits of your terminal, then run one wire through the hole in your terminal, solder it with a 25W iron to the terminal, and sold the two wire ends together.

Thanks Ian and Jon. I just checked my iron; it’s 50W so should be OK. I’ll try to get a new bigger tip for it tomorrow.
