Charles Lancaster patented the oval bore rifling, although he wasn’t actually the inventor.  I purchased a cased Lancaster double rifle in excellent condition (serial No. 3076 for 185X) and then acquired a complete wreck of a very similar gun.  The stock had been burnt, the locks very crudely replaced with rebounding Stanton locks  from a breech loader extended to fit the opening, and a major crack running right through the action area.   I didn’t take photos of the ‘before’ state, but the work involved splicing a new heel on the butt – which my friend Dick did for me as my woodwork was not so hot ( its better now) and some additional woodwork that I did manage, including replacing almost all of the wood between the two locks.  I made a pair of new lockplates, fitted with the modified Stanton insides, and made  new main springs.  I engraved the lock plates as an exact copy of the locks on my ‘good’ Lancaster.  The good Lancaster had a circular patch box but there wasn’t one on the wreck, but there was a nasty burn mark on the stock where a patch box would fit, so I made one – but rectangular to cover the entire burn mark and engraved it to match the good one – keeping the circular reference of the original.  I’m not sure I engraved the lion deeply enough, but otherwise I’m pretty happy with it – it shuts with a suitable snap.   Stock is finished with dozens of coats of  ‘Slacum’ – a mixture of boiled Linseed oil, beeswax and terbine driers, put on and then rubbed off as it goes through the jelly stage.  I had a reasonably suitable case that fitted well, which I modified inside, and made a set of tools with ebony handles.  I haven’t attempted to pass this rebuild off as original – the locks and patch box are engraved with my name and the year to avoid confusing future collectors and the case carries a ‘confession’ notice!

These pictures are what I have to hand – I’ll try to take some better ones sometime!  Click on the pictures to enlarge to full screen.

William Jover made some very fine guns, first as a partner in Nock, Jover and Green at 83 Long Acre from 1775 -, then as Jover and Bolton, then as Jover and finally as Jover and Son from 1784.  He didn’t have the same high output as the Mantons or Nock, but was in the same league in terms of quality.

Pedal Control for SIP P178 IG welder

I am putting this up in case anyone needs to do the same – I have a SIP P178 HF welder and wanted to get lessons in precision TIG welding from Jason McDougall, who said that without a foot pedal control on the current and stop start I wouldn’t get very far!  Welders with foot controls don’t come cheap, and I didn’t want to scrap my almost new SIP, so I had a look around to see if I could fit a pedal control.  No info on the web that was relevant, although there were a few pics of pedals, and unfortunately no circuits available for that model.  Under the hood I found the current knob was a dual gang potentiometer of 1K Ohm resistance, which was a bit of a problem, as I would have to substitute my pedal for this potentiometer  – I couldn’t find suitable 1K slide potentiometers to make my pedal from, so ended up with a bit of a Heath Robinson arrangement with a cord running round a drum that sat between two 1K rotary potentiometers moved by an arm on the pedal – after a bit of messing about I put in a sprung idler pulley to keep tension on the cord and a microswitch that operated right at the top of the pedal movement – doesn’t quite cover the full range of the pots but probably goes to 120 amps – so far so good….
