Hi, Does anyone know what sort of job it is to kick out the RH seat unit tube to take an inside frame exhaust?
Many Thanks

Can be done, but might be easier to buy one ready made from Sammy Miller Products. Basic procedure is:
Chop hafway between the bends, heat, bend, weld/braze an extra bit in the middle and assemble.

If you try it yourself, be careful heating the end with the bit that attaches to the end of the swinging arm - it is made of brass and will melt!

Good luck!

Hi Guy's .
Hi Roger.
"Liked that one, made of brass."
No the end was a made of cast steel, investment casting we would call it today, this part was then hearth braised into the tube using braising particles and the good old gas that used to come from the huge gas ohmmeters as I think they were called, our natural gas from the North sea now replaces that.

Regards Charlie.

Thanks.
Maybe more time than money at the moment so will have a go. Just finished the swinging arm mods.
Will take care with the heat just in case!!

Hi Guy's
Hi Alan and Roger.

Now Roger are you sure that your Tigercub sub frame is not part of the missing gold from the Great Train robbery, Cos if it melted it ent from the Triumph factory, unless they were in on the job?

Regards Charlie.

Hi Charlie

It was a while ago, but my plan was to remove the lug by melting the braze (assuming the lug was steel/cast iron, etc). Lug went all mushy when red hot. Wasn't gold, though!
