Getting ready to lace front wheel 1965 LR 8" 1/2 brake and wondered if they were only 2 types of spokes or 3 or 4. Using original spokes and the hub side look the same, but the brake side may have 2 kinds.

2 types, 20 long and 20 short in the 68 parts book for the 8", half width hub. After installation, and years of service the originals may have taken a final "set", inner , outer, that may account for the apparent differences, best if you get them back the way they were.

No there are just 2 types of spoke, note that the rim is handed so identify the 2 sides sets of spoke holes.

Spokes

9G 90 degree 151mm long Large flange side
9G 110 degree 225mm long Small flange side

Any way to determine which side of rim goes where or maybe trial and error? Notice some holes drilled closer to rim(less angle) maybe for brake side spokes.

Bill: Sorry I failed to go back far enough.

I recently put one of those together and as I recall if you press some nipples into the holes you will see where they are pointing. either toward the center for the spool side or further from the center for the brake drum. It should also be clear which side of the rim they are pointing to. With that in mind the ones going to the brake drum rim have a sharper angle in relation to the wheel rim. Once you have determined the side (brake or not) you will see the pairs are parallel (left and right of hub). As you go around the rim the spokes will alternate as to which side they should go to. There a lots of photos on line to show the pattern and how they cross over and under.

There is a forum thread dated 11 07 2014 called "Help Lacing 1966 Lightening Wheels" in which John Healy posts how to lace those wheels.

PS an online search of the title above seems the easiest way to find the article.

Got it laced today. Had it wrong a couple times, every other spoke too long. Finally found right combo and it went good.

When I laced my first rim (about ten years ago) before I did anything I put a piece of masking tape on each spoke and numbered them all.
I then took lots of photos of the wheel from both sides and with close ups too.
After I stripped the wheel I kept all the old spokes complete with their numbers.
The numbered spokes and the photos helped me tremendously when rebuilding my first wheel.
I have done exactly the same for every rim I have relaced since.
It takes a bit more time at the outset but saves a lot of time (and frustration) at the end.

Yes, I also take photos...then hand the parts to my wife...she does a lot of sewing and knitting and has a good mind for patterns...

I also took lots of pics but when I laced that way it wasnt right. It actually had to be laced opposite of pics. Don't know if rim was drilled differently or what happened. At least it's laced now with proper pattern.

as yet no one has mentioned the offset requited from the hub/brake drum edge to the rim edge

I hope you knew about and set the offset correctly Beach

it pays to measure it before one pulls all the spokes out .........its pretty important on a front wheel , i actually made a wooden jig when i did my font wheel ages back so as to get it right

Yes I laid it on 1 1/8" blocks while I was lacing it. Book said 115/16" from center of rim to edge of brake drum.

Have done good on truing rims but having trouble torquing to specs. Anyone have a system for torquing the spokes using spoke torque wrench. What I found is some torque quicker than others and not sure if you still torque ones that are right while working the looser ones. Tried this but then some spokes are overtorqued.

To keep from becoming frustrated you should start with ALL OF THE NIPPLES with the SAME tension!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If just one nipple is loose you will drive your self nuts as the loose one effects all of the diametrically opposite and adjacent nipples.

Do all of your truing while the nipples are loose (finger tight). When true check each nipple a couple of times (turns of the wheel) until all are the same tension. Then start you tensioning.

Ahhhhhh. So after true go around and snug the loose ones watching the trueness until all are equally snug.

Thx John

not sure if this will be helpful .......but hey it might give u a laugh .......when i did mine i didnt have any fancy equipment to test torque so i just got them to what i reckoned was right (been a fitter/turner all my working life) but ive also been pedantic all my life as well.

SO i took the wheel to a friend who is a piano tuner and got him to go round the spokes and hit them with a small steel bar and listen to the "ping" sound to check for even tension by the note they made .......he said they were all pretty good but only a couple needed a bit more or less and then declared them PBG ( pretty blood good)

I couldn't hear any difference in the ones he said were too "sharp (tight) or flat (;loose) " but he could hear
the micro differences in the sound

I tune to pitch/ ping tone, long spokes will be lower tone than short ones . Ping some spokes on a complete wheel to get an idea of the pitch to aim for .

My hearing is fair at best. All those years of riding(no hearing protection) and rock music. Product of the 60s I guess.

Ignoramus, your idea is a good one.

By necessity of their profession, piano tuners will be more sensitive to tone differences that most of us.
