Thread: MEET Harry Highback

Looks like a brilliant rebuild so far, can't wait to see the finnished product.

Cheers, Mick

How much more offset do you want???

You can gain about 20 mm extra just by cutting the welds, knocking the centres in and rewelding. Any more than that (30 mm +) and you need to flip the centres - however where you weld the centre back in depends on the offset/backspacing you want to end up with.

EDIT Summerfield engineering (race engineering DO flip the centres and also charge the earth) who did a set for me don't flip the centres - instead they turn down the lip on their lathe so they can move it back further.

Well did a little today..

Put second coat on the drum..



Put the speedo cog back in with a new gasket..



Put new seal in..



Painted the 4WD lever & bracket & the ball carrier..





Gave this a coat of paint as i cant fit it as i dont have the gasket & i could'nt find my gasket paper..



Studs locktighted in & backing plate on waiting for the gasket then i'll bolt it all up & its done..

Thanks Ben i'll give you a pm a bit later as the rims on your 2a are exactly what i want ever since i seen the pics of it i knew what i wanted..I have the rims but i'll get all the details off you if you dont mind so i can take it with me when i take them to get done ..
Thanks Jason..

Well got bored today so i cleaned up the block engine mounts & gave em a coat of paint..





It is a blue engine & was blue should make the blue slip fun.

Jason,

No problems. The IIA rims are flipped, my 110 rims are not.

The guy who did the IIA rims was just a backyard guy who built speedway cars. He cut the welds out with an oxy (which actually cuts into the rim bands) then knocked the centres out and ground everything smooth. To set them up straight before welding he just uses a hub on a spindle, and a simple run out indicator (a lump of steel will do for that), then welds them up with a MIG.

Because he cuts through the bands the rims can leak if there are pinholes in his welds, but I had my rims galvanised which fixes that.

The 110 rims were done by Summerfield Eng in Perth - who only charged $40+GST! per rim. They use a lathe to cut the welds off which is much neater, but I don't like the fact that they machine the centre down, or that they use one continuous weld (it is easier for them and easier to balance, but not good for crack propagation). However, the 110 rims have cone the CSR, gibb, kimberley, etc and are fine.

Well gave the engine mounts a second coat today also pulled the bump stops off the extensions & painted them..

Put a second coat of paint on the bump stop extensions & put them back on the car today thats all i got done..
