B50H Twinseat

Post by Canberra » Sun Mar 25, 2018 12:27 pm

Is there anyone making seat bases for the 3 gallon tank version of the twinseat and is the foam available?

Over the years my base has rusted and has been fixed with plates. Has anyone tried a fibreglass version?

As far as I'm aware the seats for the 3-gallon tanks were all made from standard seats by BSA, they simply modified the standard seats from the outset rather than re-tool it, in theory, you should be able to modify a standard one yourself as BSA did!
The steel base is the same metal pressing but was shortened at the front, whereas the foam was also the same moulded foam but rather than have the front shortened BSA removed a strip of foam at its widest point and glued the two halves together. The only remaining difference is the front bracket was higher so you'd have to reuse your old one.

If they were just shortening the nose, why would the bracket height change?

This is starting to sound like major surgery. I will have a chat with a guy I know who is a whiz with fibreglass and see if I can find BSA seat foam to cut back. I have found a source of original BSA seat covers.
Alternately has anyone got a good base they don't want?

I think BSA did it to raise the front of the seat slightly, for whatever reason, I seem to recall a photo of the two brackets in Brad's incomplete guide.

Ah, to ease the wedding tackle up and over the larger tank during sharp deceleration. :shock:

Oh Yes... the "Wedding Tackle Protection Department" at BSA insisted on the change, whatever changes they asked for they always got, no one was man enough to stand up to them :shock:

Worry about new ones : the sheet of steel is not oval stamped, to cross over the rear mudguard but folded; and the seat doesn't fit as it should .... <201
But don't know if all are the sames ... :(
