Found it thanks

Is it just my PC or are the measurements illegible?

Thats great, I think I've got what I need now. I tried searching on google before contacting the club but obviously didnt use the correct key words. 

Looking down at back of frame the seat stays seem parallel so dont understand why the gap between wheel dropouts is an inch more than it should be.

Do you think someone has deliberately widened it so as to fit a wider tyre for trials?

Thanks. I hadnt considered that possibility, but it would explain why it looks to be 'square'. Would knowing this give any clues as to the best method of putting the frame back to original? I would like to do this without sending to a professional as I have been quoted upwards of £200 verbally, none have seen the frame yet so might even be more. 

Any tips appreciated!

Have you compared your frame's measurements with those on the Service Sheet? ie, are the dropouts 2"15/32 either side of the centre line, or is one side 'bent'? If so, can you see the bend? Also, you say one of the dropouts is 'angled upwards', if so, you should be able to see what element of the frame is 'bent', from that you may be able to see what needs to be done

Hi, not done it yet, Im having some work done at home and the builders have blocked my bike in with materials- typical!

First thing is to work out how to project the frame centreline rearwards, so I can measure either side without stripping the frame down. I note you mention 2" 5/32 each side of centreline but measurements are different each side on the plans. I have converted the dimensions into mm so the speedo side is 63mm and the brake side is 82mm from the centreline.

I am now wondering if it has been intentionally widened as suggested by Sunny as everything seems pretty much parallel. The only obvious signs of bending are the brake side dropout and on the same side the saddle mounting slightly askew. This suggests any changes made have been made to the brake side chain and seat stays. Just why the dropout is angled updwards I cant imagine.

I am keen to sort this out without going to a professional with a jig as the price quoted me over the phone was in excess of £200 and probably nearer £300.

I have attached some images i took previously which may help I will get some more when I can get to the bike.Rear-frame-alignment-1.jpgRe-sized-speedo-side-1.jpgRe-sized-side-view-1.jpg

My mistake - 2"15/32 on the rhs, 3"7/32 on the lhs (if my calculations are right), which may account for your 1" difference. Have you a measurement for the hub width?

Where would I take the measurements to/from?

In previous posts I mentioned this rear wheel is from a later plunger and has been adapted by fitting a narrower spindle (to fit my 1950 frame) and different bearings. I thought all D1's, whether rigid or plunger had the same width of hub, but I stand to be corrected. The conversion was done by a professional so I must assume its been done properly.

From memory I think the gap to the frame with the brake side tightened up, and speedo side loose was about 5-6mm, but this includes the brake plate lock nut on one side and the speedo lock nut and a washer on the other.

1.It shows where the measurements are taken in the service sheet!

2. Perhaps that is the problem, but I have lost track of the number of questions you've asked about the rear wheel - such as this one: ** Please log in to view **

That post needs to be taken in context, its a wheel I bought on ebay to replace the one fitted to mine. Sold as a rigid rear wheel but turned out to be another plunger wheel and in the end I returned it. 

I am a pretty practical person but dont have much experience of motorbikes. I wont ask any more questions. Sorry if I have caused any problems to you or any other forum members.

That's not necessary at all. You just seem to go from one problem to another without seemingly fixing the first problem (at least, to my view). I see every post on the forum, so I do tend to get a bit narked (a bit? some would say) from time to time - other members I can't speak for, but most likely no problem.

Keep going, you'll get there in the end, just remember that as a Member, you have access to all the tech info you should need, besides that in the open forum.

I am not convinced the rear downtube is vertical.
