Ped,
Does this style of barrel adapter work on the Sheridan Bluestreak? ls it basically held by a push on fit with a grubscrew?

Yes he does them for blue streaks too and held on with a grub screw. He's helped me out several times after buying junk that doesn't fit.

The Benji has had a few more tweaks as it still wasn't dumping all the air. I played around with the valve and hammer springs, mounted the red dot further forward to allow easier pumping and fitted one of Peds silencer adaptors. Next I will see what power it's making and accuracy test. I've enjoyed this one but I may well sell it in the future to fund something else. I've now got a new project of sorting out a very rough Sharp Innova.

I had a chance to see what power the Benji was making after a service. I was concerned it may have gone over power with this type not having a blow off valve. Thankfully the power didn't exceed 10.5 ft-lbs on a maximum 8 pumps and being .177 it would be harder to exceed 12 ft-lbs. I won't bother testing it with 4 pumps which is what I'll use in a back garden and at the local club. Before playing with a selection of hammer spring weights and lengths, it wasn't dumping all the air. There wasn't much point in testing the efficiency until it was sorted with the follow up shots being far too inconsistent.

I hope you enjoyed my project the next one I have almost finished , this Sharp Innova thanks for looking

An early .22 mk1 Sharp Innova possibly over 40 years old. With a plastic breech. It doesn't feel as solid as the Benjamin's and Sheridan's but it really is so light, pointable and powerful which must have been refreshing to see in the late 70s.

There was quite a few things wrong with this Innova, a cheap buy lured me in but of course I ended up spending a lot more than I wanted on fixing it. Still, it's an enjoyable hobby.

The rifle was really dirty but underneath was a decent rifle. There was a lot of congealed grease inside the pump tube which would be lowering the power, if its lubed properly with 30wt non detergent motor oil, it would very hard for this dirt to build up in the first place.

The stocks are apprently Japanese walnut and they are quite soft, this one had crack in the stock, possiblly from bad pumping technique as it's not advisable to grasp the grip and stressing the stock.

A trip to a knowledgeable friend and a restorer of antique flint lock guns, had this remedied and it now feels very solid.

The woodwork was very dried out which wouldn't help cracking, so it was well nourished with walnut oil.



It had the common missing pivot pin and e clip bodge up where they've shoved a bolt through.
It worked but it was replaced with a correct solid pin and allen head screws to secure it.

I was surprised to find that theres quite few more seals than the Benji and these badly deteriorated ones were replaced with Peds upgrade kit and included was a poly inlet seal and even a new inlet valve ball bearing.




The front end plug has seen better days but it works and the breach is in good condition, no cracks but the usual scope ring marks on the dovetail. I have fitted a Simmons pro diamond 1.5-5x20 similar to the white tail classic and is light and compact like the rifle.

How did you manage to rebuild it on your own? It is a miracle for me, really. I am a big fan of guns of all types, but it only with regard to active use. But I am a complete loser when it comes to any remodeling. Where are you from? I would love to ask you to do something with my older guns. I am from https://worldcams.tv/netherlands/amsterdam/dam-square if you are interested.

The wood stock versions have been discontinued but the plastic versions will still be fine and durable. Check there won't be any hold ups with UK customs if you do order one.

I don't think I've visited that site before, it says wood stock models are out of stock but they have the plastic ones.

m6 from what i remember
i have one in a box i got ready to convert ,i'm going in there to get some falcon parts out so i'll get it out

[ratbuster2240]

Thanks Ped you're always very helpful, I've ordered some grub screws to try.

The Birchwood Casey bluing kit arrived today. I've had success in the past with this on Crosman tubes and hopefully the metal on the Sharp will also like it, but it can be a bit hit and miss.

The barrel was in better condition but the pump tube could have done with more sanding.

That looks great from pics

Its helpful to have a clean work area so you don't lose any tiny parts, a schematic diagram and online tutorials. If it's the first time stripping a gun, taking photos along the way will help when you put it back together.

It's amazing the performance that can be had from just a clean, polish and fresh seals. It's also satisfying doing it yourself and if you get stuck there's very knowledgeable members that are willing to advise.

i've just pulled out my other ally breech and i think i altered the trigger spring set up by using a much smaller spring (from a pen i think) and i made a brass insert to replicate the innova one
the breech i tapped a larger size
i'll make you one through the week if you'd like
