Carbon Fiber Sleeve on the IZH 61 -- Part 1

Been shooting the short barreled IZH 61 trying to find my ideal set-up.   Looks like Nick and I have done over 20 blog posts on these rifles.  After adding picatinny rails, sling mounts, mounts and red dots,  I found some cheap carbon fiber tubing online and thought I'd sleeve the barrel, too. Why?  Well, because it would look amazing. 

The tube ran about $7 shipped from Hong Kong, and 4 weeks for delivery.  The IZH 61 barrel has a nominal OD of 13mm.  Not needing this for structural support, I opted for a 13mm/15mm  (ID/OD) carbon tube.  That equates to a wall thickness of 1mm. 

The tube arrived and as I suspected, didn't quite fit over the barrel.  I stripped the barrel down to bare steel, then changed course and sanded out the ID of the carbon with 150 grit emery cloth on a long mandrel. 

Got a snug slip fit.   Not shown:  re-blued the barrel.

Eyeballed the length and cut it 1/8" long with a hacksaw.  Wrapped the tube before the cut with masking tape to help prevent splintering.  It can be helpful to treat carbon fiber like wood or fiberglass.

Faced it closer on the lathe then finish sanded the edge.

This isn't necessary, but I opted for a semi-permanent installation.  Pretty sure I can break the epoxy bond with either a heat gun or a torch if I ever change my mind.

Thin coat on the barrel and slid the sleeve home.

Used a gray scotchbrite pad to knock back the gloss finish to a matte.  Ran out of time about here.  Still need to make a new barrel support for the larger tube size.  Despite my recent misadventures with plastic, there's a piece of acetal on the bench. 

Hopefully I can get to it tomorrow.

Adjustable QB Recoil Pad Ver 2.0

I couldn't warm up to the plastic recoil pad spacer I made for the QB a few weeks ago.

Found a piece of .500" thick aluminum and started again.  Slotted with a .250" end mill for shank clearance...

And cut the T-slot.  The slot is the same .500" wide x .125" tall size as previously used. 

I'll spare everyone the shaping and sanding pictures.  It was the same, but worse, as the aluminum is a lot harder to grind than plastic.

Put a slight angle (about 5 degrees) into the base of the spacer where it fits against the wood.   It's hard to see in this picture due to the silver color washing out.  May revisit this and add another ten or so degrees.

Much happier with the results.  I've still got a Bisley adjustable pad to fit to another rifle, but I need a break from shaping aluminum butt plates. 

More soon.

Findlay Airgun Show Finds

Here's some of the stuff I found at the Findlay show last week.    

At $5/tin,  I couldn't have done any better on pellet pricing.

An inexpensive Daisy target aperture. 

Don't have a plan for this sight yet, but it should fit a variety of rifles.  

A Hammerli Master target pistol from noted collector Larry Hannusch was too good to pass up.

I read an online review where the writer claimed that the Hammerli was what a Crosman 2240 wanted to be when it grew up.  That might be the best way to describe how much I like this pistol.  

Some projects coming up:  The adjustable recoil pad got a revision, some carbon fiber tubing for a barrel sleeve, wood grips for the Hammerli...

Check back in a couple days.  I'll have something up.

2017 Flag City Toys that Shoot Airgun Show Findlay, Ohio

The 12th annual Flag City Airgun Show was today.  At 9:05AM, Dan Lerma called us to attention and let Boy Scout Troop 308 present the flag for the Pledge of Allegiance followed by a short prayer. It was a fine start to a great show.  It was packed from the start.

I'm just going to throw a few pics up to show you some of the things I experienced. 

No, these aren't all mine. 

There were BINS of repair parts.

A display table of gorgeous vintage Walther 10-meter rifles.

Tubs full of guns.

Mr. Hollowpoint was on hand.  

He brought his 20mm rifle.

Tom Gaylord had a few tables of goodies that he's show us on the Pyramyd Air blog.  

An old Crosman adapter to let you shoot .177 pellets through your Series 70 .45Auto.  Yeah, its also new in the box.  And it wasn't crazy money. 

I'll get another post up in a few days and show a few of my acquisitions.  

Thank you to all the show organizers and vendors for making the show happen.
