Rear wheel build

Post  gwr1475 on Thu 16 Feb 2017, 5:00 am

Hi All


I am looking for some advise on my rear wheels. I am at the point where I need to add the radius where the T meets the rim. I am using JB weld. I ran a bead of it as best I could and then ran my wet finger along it trying to make a radius. I guess my question is how big of a radius am I trying to achieve. I really think I have made a right mess of the job. Will try a post some pictures

On Crystal I made to match the dressed welds on the ring. What ever looks good to you as long as it does not interfere with fitting the spokes. 

I actually used body filler as thicker than JB weld so easier to finger in to a nice profile.

I tried JB weld on the wagon I built, seems like ages ago now. I found it to be too runny and then an age to cure.
So on the Engine I used P38. It was so easy. put it on with your finger and after a few minutes whizzed round the wheel with a bull nose burr. Job done.
Each pair of wheels filled, smoothed out with burr. General rub down and primed in a day. That'll do for me.

I used body filler on my front wheels and it was a nightmare.  Went on lovely and sanded easily but had problems with it cracking around the joint between it and the metal when banging home the rivets.

I used JB Weld on the rears following advice from other builders and Found it was quite easy to finish and took the abuse of hammering home the rivets without cracking.

Many thanks for all the replies. I think I have it all shorted out.

I am struggling to build my rear wheels.

I have blocked up the rear hub by 5/8 '' Brake band side. Is it normal to have to bend the spokes this much. There is a 1/2'' gap under the spoke.......

I have tried adjusting the spokes but when I go to put the the second set of spokes on (outside t ring) None of the holes line up Its like the spokes are to short.

i don't remember having the gap, but I did get the spokes in the wrong order, so some were long and others short.   Took a bit of time to sort them out again.  

I've checked my build notes and I did the same, brake band down and 16mm packer under the hub, I'm wondering If either the hub is upside down, or the spokes are the wrong way, but I'm sure you'd have checked that.  I didn't have to bend mine.

Hi Rob,

Yes all the spokes for both t rings have gaps. Some have less, but more or the less all over the place.

The oiler hole is to the front of the wheel.

To be honest. I never spaced my hubs. Just bolted them up then checked the measurement once one lot of bolts in.

Hi Lynnr,

I did try that for the rear right side. I have ended up the just about 3/4 inch instead of the 5/8. I can't see that being ok, so going to take it apart.

I wonder if my t rings are in the wrong spot or the spokes are wrong.

Hi,
Not sure if I experienced the same thing but I had an issue that may be similar and in the end I eased the holes in the spokes on one side of the hub.



I had to adjust the bends to get the right offset for the hub. the numbers are how far in mm that I needed to adjust the holes. Once all glued in place it won't make any difference.



If yours are further out than this it may be the distance between the tee rings on the rim.

Hi John.

That is what is happening to me,

Did you drill out the holes in the hub side of the spoke to a larger size hole.

Hi Mark,

I altered them just on the one side by elongating the holes rather than enlarging them. The more difficult part is to get the countersink moved I did this on a small mill but a bench drill would probably do the same thing if you hold the spoke firmly.

I found a photo of the altered holes. Hope this helps.

Haven't read all your post in detail (naughty), but I'm assuming you are in the secind series build as am I. STW issued a modified set of spokes, as one of the T rings in one of the back wheels, was welded a few mm out, and it as easier to issue modified spokes, than reposition the "welded" ones. Have you measured both wheels. Oh, if this has been covered, then I apologise for not reading it all.

Yes I am in the later build. Only one of my wheels was affected and I did get hold of some longer spokes but these were too long for my wheel so I altered the standard ones. It may be that mine was just slightly out of position.

Did you use a ball nose end mill to move the counter sink over?

No just a countersink bit slowly with a bit of lubricant. In fact I didn't do much moving sideways with the countersink I just went in at the new position. As I was on the mill I used an end mill rather than a drill to try and avoid it drifting to the old hole. With a drill I would keep it as short as possible to avoid the flex.

Rear Wheel Build

Post  Heavyhaul on Mon 06 Mar 2017, 6:24 pm

Hi everyone,
I had the same problem with my offside rear wheel on my showmans, where when you laid the spokes out they appeared to be to long. I fitted the spokes to one side turned the wheel over then had the same problem the angles on the spokes were all wrong, plus the holes didn't line up.
I contacted STW and as I was going up to Daventry to collect a kit, I took my wheel with me showed it to Craig who changed the set of spokes for me and all is now ok.

Regards
Steve
