Best tool for porting ally intake

[nick_968]

I need to mildy grind the ports on my intake to match the shape of the intake ports on the head and the gaskets.

Can anyone recommend the best tool or stone to attach to a drill or my dremel. The regular stones I have on my dremel get clogged very quickly and dont really have the guts for the job.

There are various threads on this further back in this subforum, if you trawl back.

http://specialtycarbideburs.com/basic-bur-cuts/ many shapes and sizes to choose from to suit your application. People use all kinds of grease, oil etc to minimise clogging. Might be worth a test piece before you attack your ports with it, to choose which grade you want to use etc.

Ally is so soft you can do a lot of work with dremel and sanding wheels

Ally cut carbide burrs will do the best job for stock removal with very little loading up, double cut regular carbide burrs will do an effective job if they are run slowly enough and with suitable lubricant (WD40, RTD or dry chain lube), you can follow this up with spira bands or cartridge rolls to give a good smooth finish.

Plenty of carbide burrs on Ebay, or try www.ruffstuff.com.

my late father of 30 years in the porting business used tungsten carbide burrs regulary dipped in parafin.
