Finals have arrived for the next round at Shelsley Walsh on 10/11 August.

This is a BIG meeting, rounds of the Midland and British hill Championships, so the very fast boys arrive.

So there are 3 of us in the class, myself and the usual Norma and Chrono sports cars with well over 500 bhp and all the modernatity that brings.

At least the Lola will get into the allotted garage spot in the busy paddock, I doulbt the other 2 will be able to get the cars into the garages.

The garages are very quaint, but erected so long go Austin Severns fit easy, rest is a tight fit.

On a negative note, cleaned the car well after Prescott and have found a 3" lone 'line'/ 'crack' in the one rear Dymag wheel.

The line was not there 6 miles ago when i last cleaned the inside of the wheels.
I suspect my lovely DYMAG magnesium alloy wheels made in 1976 are reaching their end.
Fortunatly i have another pair that fit of the right size, so the best one will be used to replace the suspicious one.

I can then get the bad wheel crack tested.

This wheel looses no pressure, so maybe not a crack.(?)

Not the kind of thing you can jeopardyze with Graham. I remember when we used expensive brake discs, vented and drilled, a small crack joining two or three drilled holes decided to become a long one… Speed was above 280 kph (old Spa layout) and this almost sent my RSR in the barriers. Sometimes, savings can be expensive…

Indeed.
I can reach 104 mph at the finish at Shelsley Walsh and there is NOWHERE to go if it all comes unstuck.
The tyre is on the spare wheel now so all ok for the next event and the rest of the events this year.
I now have time to have this checked carefully.
The 'cracked' wheel rings like a bell when tapped, but the spare rings brighter and far longer.

Not a good test, but enough to have a propper check done.

On the contrary, I think its a good test and as you say enough to order a change and a check. This confirms a old adage, keep your car clean anytime!

Almost one month before Shelsley Walsh, no hurry.

I do not trust specialists!
In the past have been down to the wire with promises.

The car now is sound. The 'new' wheel fits, has the tyre on and balanced.

The ammount of balance weight is huge, but i do suspect the quality of the balance done.

I can run up the hill at Shelsley first practice, and if the wheel is poorly balanced it will show. BMTR will be there on the Sat, so can always get them to strip the weights and get it sorted.

The tyre fitter had great problems getting the wheel center to sit square on the balance machine and clamp up flat with the cone and clamp spinner (I was there'helping').

My local 'rough=-n-ready' tyre fitter has balanced these rims before perfectly, so may yet take it to him with a £5 for him to check it.

I hate it when thingas are not resolved.

I always deep clean the car on he Monday post an event; cleaning can reveal so much.

+ 1 ! I had many issues with painted rims, mainly because the paint used was "epoxy resin" its very hard to find a good specialist here.
