    Today's bodge...sorry, expertly engineered solution was, to straighten a .177 factory screw cut HW90 carbine barrel...With the breech block cushioned in the big vice, this bugger was a bit too short to get a hold of and bend by hand so I turned a couple of bushes to fit on the barrel, giving plenty of clearance around the threaded muzzle, slid the big pipe on and janked it back, job's a good'un!...

    The small bush was pushed up against the breech block but it could be held in place by a small brass or nylon grub screw to apply pressure where ever you want it along the barrel.

    This barrel was given to me as a lost cause by a member of SDFTC on Sunday last, at the club. It was bent upwards at the breech block end by about 3mm or so over the length - measured using a steel rule off the breech block. He is also a member on here so, Tom, if you're reading this mate...thanks for the barrel (...and, of course, you can have it back if you want it mate )

    Many thanks again Dave for your kind help in organising transfer of photographs....

    Just a few words on the Maxi Scope jig:
    This was a bit of a prat about to see if it was possible make a tool to help in the removal and replacement of the scope rail. I was messing around with one of my Superstars at the time, I had already removed the rail by the usual bashing method as the "cushions" get screwed up anyway despite applications of WD40 to free up the "stiction".

    The photographs show the component parts all were scrap bits apart from the threaded bar and wing nuts. Because it was intended for the Superstar, the aluminium base has cut-outs to fit between the trigger and cocking link spring brackets - this stops the base sliding in opposite direction to the "slide". The base has two pieces of wood to protect the cylinder and has a cut-out to clear the safety lever. The slide has a semi-circular cut-out that butts against the rail, but, has clearance of the cylinder - probably a flat or square section would do, it's just I like giving the ML10 a twirl now and again. On the opposite side of the "slide" there is a square section screwed on with a threaded hole which can be used with a set bolt to draw the slide. Roughly in the middle of the "slide" is a cross piece, again, screwed on - this, combined with the little pivoting "Tommy" bar can used instead/or with the draw bolt to move the "slide". The frame is just pieces of 'L' angle with some cross supports and round bar that rests on the "slide" and a pivoting cross piece for the "Tommy" bar. Not much pressure is needed by the wing-nuts just to compress the rail "cushions" a little to enable the small amount of movement needed by use of the draw bolt and/or lever. With the set up as it is, it is suitable to replace a rail, to remove a rail the end of the "slide" that butts up against the rail needs to be moved in-board a bit - roughly where you see two countersink holes.

    It is a bit over the top, as with a bit of patience and a a padded clamp, the rail can be moved the 6-10mm(?) needed with a few taps on the rail with a soft drift and light hammer.

    For use on say a Challenger, a means of stopping the bottom from sliding instead of the "slide"! This could be done with a "Jubiliee" clip clamped to leather surrounding the cylinder, for the other direction, a couple of long threaded rod attached to the jig and the other end to suitable piece of wood across the breech jaws.

    By no means it is the best solution, just an experiment and many of you could improve on it - I just don't feel like doing a Mk2!

    Regarding the BSA trigger block jig: The adapter shaft that is shown fixed to the jig, is also used for other tools. The threaded shaft on the "G" clamp is bored to take the shaft of the adapter. When pressure is applied, the adapter with whatever tool is fixed to it, is easily turned by hand if needed because the adapter shaft sits and pivots on a single ball bearing inside the "G" clamp threaded shaft.

    All the best and have some fun - Where is that woman in A Bargain of a Lifetime when she is needed?

    fitting pistons

    Hi , I rebuilt an old webley falcon today, I had made a new piston & seal, the seal is ptfe with o ring, when I came to inserting the piston I did not want to damage the seal by pressing it through the internal thread. I do have some brass shim stock somewhere but could not find it. so 'thinking on my feet' I spotted an empty beer can & cut this with scissors, formed cylindrical 'guide/guard' I put this in the end to cover the threads & pushed the seal/piston through. sorted! this would work with traditional leather cup washers as well. hope this might help somebody?
