Brass barrel pivot washers
« on: May 25, 2012, 12:15:51 PM »
After something on the order of 10,000 rounds, the plastic barrel pivot washers on my Nitro Venom finally could take no more. The pivot bolt was as tight as I could get it and still had side play. I could cock then slap the barrel sideways and get it to hit left or right of POI. I picked up a pair of 5/16 brass washers at Lowes the other day thinking it was about time I did that. What an easy thing to do. Just used a dremmel sanding drum and removed a little from the outside edge then cleaned up the faces with 220 grit paper to give it some texture to hold moly paste and wear in. It was a little tighter fit to get them back into the receiver but nothing unreasonable. When first installed I think I may have over tightened the screw thinking it would need to be torqued to the max to get good results. It seems that much less pressure is now needed to keep things in line. After some minor scope adjustments, it seems to be grouping better than ever. I was concerned at first that it was not grouping as well as before but after 100+ shots it seems to have settled in.

10,000!  That's a lot of shootin'.  Thanks for the specs on what you used.  I'll look for some next trip to the hardware store.  Tom

In case you guys did  not know this, I have made the brass breech washers specifically for the Crosman guns.
No more loosely fitting or side play in the barrel/yoke in your Crosman break barrel air guns.

Two brass washers from hardware store, nut and bolt that fits through the center of washers, electric drill, file and some sandpaper. Make sure the bolt is long enough to hold the washers about an inch away from the head of the drill chuck. With both washers on the bolt, screw the nut into place so the washers are locked down to the head of the nut. Put the other end of the bolt into the drill and lock it down. The take the file turn the drill on and take enough off the washers till they match the size of the old plastic one. If you want to make installing easier then hold the file at 45 angle to each side of the brass washer sandwich while the drill is turning. This will give you a nice tapered edge just like the plastic ones have. Use the sandpaper to take any sharp edges off as well as put a little roughness to old Molly. i would suggest some thing finer than 200 grit but that's up to the individual.

A,most exactly how I make mine! I put my belt sander upside down in a vice and turn it on, and use it in place of the file. Works great, and washers fit perfectly. The 45 degree bevel does help with installation.

I found brass washers at Home Depot for $0.98 per pack of up to 12.

http://www.homedepot.com/webapp/catalog/servlet/Search?storeId=10051&langId=-1&catalogId=10053&keyword=brass%20washers&Ns=None&Ntpr=1&Ntpc=1&selectedCatgry=SEARCH+ALL

That is sure a lot cheaper than paying $8.50 for only 2 brass washers.

I don't mind a little extra work to save a few bucks.

i have done the home depot version of the barrel pivot washers and got  a set or two from airgun toys both worked well but i don't think the brass washers were of the same quality brass as the ones i got from air gun toys. the home made ones wore out quickly for some reason....

I went the homemade Lowes washers route, and found the brass washers wore too quickly despite polishing, drilling for lube retention etc. Ended up using Zinc.

For what it's worth, I will tell you guys something. Precision is everything. ;D ;D There is a huge difference and wear factor using a precision CNC machined and beveled brass washer and one made on the bench using a low quality metal whether brass, zinc or steel.  :o  Zinc or steel should never be used on most guns.

A machined washer will normally last forever. ;)  Hand carved don't usually hold up well, are not precise fitting and will not pull down or seat evenly on the yoke which in turn can have an impact on accuracy and wear and tear on the pivot bushing that the bolt itself rides in.  :( :'(

It is well worth paying a few dollars for quality for something that will last the life of your gun.  ;D ;D

do you need a spring compressor to install barrel pivot washers?  I've never tuned a gun before so I'm a bit of a newb.

I just think it is kind of important to me to support those that offer their products on this site.  Its not just the products but things that have taken them years to learn are ours for the asking.  I also understand the fun and enjoyment of making/modifying  a part, done that plenty!  I figure in the long run my money does better spent here whenever I can.
