Title: Sticky TKO LDC
Post by: 7624452 on November 03, 2012, 07:40:29 PM
 I just received a TKO LDC.  I put it on a 14 ½ inch barreled 1322 to test it.  I pushed it on about an inch.  It works really well, but when I tried to remove it I could not get it off.  I do not want to damage it and it is intended for a different gun.  Any suggestions?

It is for your gun. They press fit on, then you tighten the two set screws. After removing it a few times it will get easier. Make sure the set screws are loose before removing the brake!

I have EXACTLY the same problem, and have been thinking about:
1) Wrapping layers of paper towels/masking tape around the barrel just behind the LDC to act as a heat shield.
2) Putting the barrel with LDC attached (or whole gun?) in the freezer for a few hours.
3) Taking it out and immediately hit the LDC with a hair dryer on high while rotating the barrel for ~30 seconds to one minute, then pull on the barrel end of the LDC (while wearing a glove).

I've used this approach successfully for other stuck things in the past and thought it would be safer than banging on things, at least as a first attempt.

I will admit to having tapped it on (to avoid twisting as mentioned in the instructions) a little harder than I though proper at the time. Turns out I was right, and a dummy, at the same time.

They are normally undersize by a  few tenths to make for a tight and concentric fit.

Get a 3/8 wood dowel and some 600 grit emery paper and polish the ID a little, it's made for 7/16" barrels, just like yours. :-*

I'll do a little sanding whenever I manage to get it off.  I thought I would be safe by only pushing it in an inch.  It appears that I will have to take the gun apart and tap it off with a wood block.

You can't just turn it while pulling?  I can never pull it straight off.  Have to rotate it to get it moving.

If all else fails, drill a 7/16" hole in a piece of scrap wood. Insert the barrel and tap the TKO.

wiggle not twist while pulling.try a little vigorous wiggling

Post by: 7624452 on November 04, 2012, 04:19:25 AM
I finally got it off.  I drilled a 7/16 hole in a block of wood and found a piece of metal tubing that was a little bigger than 7/16 and tapped it off with the tube over the wood block (also had to do a little wiggling).  I also sanded the inside of the tube a little with 400 grit emery paper followed by crocus cloth.  It is still tight, but it now goes on and off without too much effort.  Thank you all for your input.

I have a TKO and went through the same thing. Before I even got it in place I did the inside sanding.

The TKO is nice product. I think what happens is they are made at a certain inside dia. for Crosman 7/16" barrels but if you get to measuring barrels you will find some differences in outside dimensions. When I got a Clague brand he asked for measurements in three places on the barrel so the the fit would be perfect....it was  :)

For sure, fits on my 2240 just fine, had to drive it off my 2400 ( the barrel IS bigger )

7/16 is .4375

the 2240 is .436

the 2400 is .439

I did not take the TKO off the 2240 nor the muzzle brake on the 2400 to measure at the crown ...

I'm sure it could be different at that location ...

Got one in front of me.  My calipers say it is .435, in several places but without taking it out of the long steel breech nor taking the MB off of it.

my LW barrel is no where near that size but i think its a larger od compared to jbert's barrel mine is a very tight fit in the A Storey LDC i have havent tried it on the stock 2240 barrel tey i'll do that also

I don't know.
It's possible that Crosman might order their LW barrels at a different barrel diameter than LW stock barrels.

I think I found the answer from a link that I previously posted.

my lw barrel came from droid.i have no idea where it originated from,maybe droid can give more details on it
i can tell you this it has a target crown on it well i think thats what its called.its recessed with a thin lip around the edge of the barrel,like the crowns muzzlemack and the .25 marauder barrel have
Title: Re: Sticky TKO LDC
Post by: Fronzdan on November 05, 2012, 06:29:54 PM
I have an LW direct from Crosman and can measure when I get home.  But it can't be far off from the OD of the regular Crosman barrels.  I noticed no difference when mounting to a Crosman steel breech or fitting a TKO on it.

The crown is clean and precise, but nothing like what Ed is describing.  Its basically flat.  So that one was probably a custom LW that Droid had.

i'll see if i can dig up a reference pic.found one this is the type of crwn on my marauder .25 barrel and lw barrel.i like these crowns wish all my barrels had them

Well, I got it stuck again.  Even with the sanding I cannot get it off the second time.  I just broke the wood block I made so I will wait until I feel like making another.  I sent an email to the guy that sells it and he replied that he cannot do email because he types too slow.  I think I will probably buy a LDC made of metal next time.

Nice!!  That's not how the LW from Crosman looks. That's how the LW on my Talon looks though. The OD on the Crosman/LW is 0.434", so it's slightly smaller than standard barrel.

 The second time was much worse than the first.  Even though I had done some sanding, it was not nearly enough.  I finally peeled off the plastic to see what was inside.  The rear part is a 1 7/8" delrin tube secured by a set screw.  I removed the front part and was still unsuccessful in removing it.  I then used the method that always works.  I clamped a set of vice grips to the barrel and another set to the delrin tube and twisted it off.  I used heavy cardboard to cushion the barrel and the tube, but it was not strong enough and I marked both the barrel and the tube.  A bit too late I remembered that the only thing that will keep a set of vise grips from marking something is leather. The barrel measured .435 at the end and .436 11/8" from the end (the point to where it was on the barrel).   The moral of this story is not to shove your part somewhere you haven't checked out. ;)

It's not much of a problem.  I'll either polish it or paint it black.  If I had known what the "carbon fiber wrap" was I would have ordered it naked.  Now it looks like I'll be sanding on it for several days.  At any rate, the thing does a real good job of preventing the lead dust from polluting the atmosphere.

Are there any in-depth books or blogs or even websites where one can learn the real deal ins and outs on doofing and lead dust collection.  There has to be a science to it... general rules of thumb... calculations of optimal aggregate hole diameter and placement for specific LDC length and based on projectile diameter and speed, etc.  Please tell me its not a hit and miss type thing... or even mostly for looks.
