Re: Tire circumference with the illusion of speed and handling

Thank you Duncan M. for warning me about the tires not being capable of fitting into the wheel wells when mounted on the wheels. No, we do not have the wide rim wheels from Bob Gruneau. I do remember having to wrestle with getting the wheels mounted when the Model A Ford tires were in use. I did not...

Re: Tire circumference with the illusion of speed and handling

Yes, it is hard to get information about tire circumferences. The measurement usually must be derived mathematically from looking at the "overall" tire diameter -- but even that information is not always available, or perhaps totally dependable. And then, like dummy me, the wrong formula can be appl...

Re: Tire circumference with the illusion of speed and handling

Yes, agreed that the wrong formula was used to calculate tire circumference. Therefore the differences are not as great, but are really as observed in Steve W's comment. The order has been placed for tires with diameter of 31.40 inches, and using the proper formula, will equal circumference of 98.65...

Tire circumference with the illusion of speed and handling

The actual diameter of original unworn Dunlop 19" tires for the MGTC is estimated around 27.5 inches. In the past, for economic reasons, we have used 19" tires that were meant originally for the Ford Model A. These tires fit well but had an actual diameter estimated around 32 inches, when not worn. ...

Re: MG TC8204 - Front axle beam and Mike Sherrell's remark

The the 3 TC's that we are very familiar with all had the axle lettering for determination of the proper castor/caster of the kingpin eyes, facing to the rear. This is illustrated in Mike Sherrell's book TC's Forever at page 111 regarding the front axle, as well as being mentioned on page 113. His q...

Re: TC EXU Turn Indicators on older TCs

Then we will probably do the EXU modification and just use bright incandescent bulbs in the lamps -- and not have to use LEDs with the relay modifications those entail.

TC EXU Turn Indicators on older TCs

Please help us resolve a problem with preservation of "Boxley" -- an early TC with #0820. Around the time of, or before, 1968 there was a Ministry of Transport rule about all cars needing tail/stop/turn indicators with no exceptions. At the time, the Scottish owner hung aftermarket lamps that were h...

Re: more on rear leaf springs.

Yes, once I accidentally left out some leaves but the ride was not smoother, just easier to bottom out. What gives a smooth ride is having original springs thoroughly de-greased and cleaned then re-arched, assembled accurately and completely with the teflon strips between the leaves. If you do not h...

Re: floorboard supports

Yes, floorboard supports are original and they are necessary even though some of the floorboard rests on the frame. The supports screw or bolt onto the back of the rear deck riser and the lower flanges allow the floorboards to rest on them. Bolts or screws hold the floorboards down onto the support ...

Thanks for the advice. Will check ignition timing and camshaft timing in the next few days, as well as carb mixture. At speed it just keeps getting hotter.
