View Full Version : Timing (o'clock) for Williams aluminum receiver

I've got a Williams and it is just short of 11:00, maybe 10:45, is that OK or do I need to take a little metal off?

I just got mine back, and would also like to know what it should "Hand Time" to! Maybe Dwight could shed a little light on this for us!

In response to your questions about where the timing should be:

Because of the various barrels that are available for build, the timing we have found varies from about 90 Degrees (9 O'clock) to around 30 Degrees (11 O'clock) BTDC, depending upon a new Imbel barrel to a used R1 barrel.
I would not recommend that you attempt torquing a barrel to TDC that hand indexes before 45 degrees (10:30).
If the barrel hand indexes 45 degrees or greater BTDC, the barrel shoulder should be turned to bring into correct timing prior to torquing into TDC.

Hope this helps :)

Thanks, I'll start my next build now.

and what is the corollary to the situation where the barrel times early? What is the minimum number of degrees or torque to install a barrel?

Mr Williams posting did not tell us anything?

Where should we make it time? 11:00?

I don't think so.

Dwight said, "The barrel timing is adjusted between 5 - 8 degrees BTDC. I realize that that is not normal for most of you, however is quite necessary in the aluminum receiver. 7075-T651 aluminum doesn't compress like 4140 does, and with the hard anodizing as well, if you try torquing the barrel with 15 to 20 degrees TDC, you'll destroy the receiver or break your receiver wrench."

5-8 Degrees ........ 11:30 sound about right?

If each clock position is 30 degrees then
5-8 would be around 11:45.
I just started barreling my Williams receiver last night. I tried a new DSA U.S. made barrel and a new Steyr barrel. Both are hand timing at about 10:30. With the barrel in the vice, I used a receiver wrench and torqued about 6 degrees further with 40 - 50 ft*lbs until the barrel slipped out of the vice. I put the receiver wrench in the vice and used a 1 1/16 wrench on the barrel flats and without a cheater bar took it 8 degrees further. Ended up at 11:00. So if I sand the shoulder down so the barrel hand tightens to 11:30 it should install without trouble.
"I edited this post after rechecking timing with a bubble level to give more accurate results."

That is what I was worried about; for the normal mechanic oriented guy it would be WAY Easyer to time these with the from Williams Arms supplied washers....But because of all these USELESS COMPLAIN"S about "over timing" without washer's Williams Arms changed the timing on their second rec. run.

Result > To do the job right now we have to use a lathe again :mad: :mad:

Or some of you guy's get sanding disk's or Dremel out again, what isn't really the right thing to do in MY opinion.

Got that right! L1a1's are great for the home
do-it-yourselfer. Love breaching washers.
These stupid metrics rareley ever time ideal, and are a pain to get close.

The last few Inch rifles I done I timed them
by torqu required TDC at 125FTLBS.
What is the torqu spec on these Williams receivers? (same I assume?)

I've always been told about 12-15 degrees from TDC or 1130. Anything more is too much and you will either crush the receiver or never get the barrel off again (with a normal barrel vice).

Take Care.

Larry Jones (larphred) just spoke with Dwight about this and emailed me. We should relieve the shoulder until barrel hand tightens to about 11:30.
