Very informative & detailed work process.... more info on the compressor cfm size & if it ran on a 13amp supply please, and if it was adequate for the job would be appreciated, as i would be confident on your judgement on this..... Thank you
Thanks for watching. Compressor is a SIP 3hp 13a plug, V twin, 14cfm 50L tank. I found from testing and research a higher flow at about 60 psi gave good results and working at a steady rate wasn't overtaxing the compressor too badly. This was as big a compressor as I could go without going to 16a or more. You're not going to be working at industrial levels but I'm happy with the performance for a home shop. Cheers and all the best, Ade
Great work. Do you think it would be possible to do the same with cast iron? My Ariel 500 twin port head needs spigots inserted to replace the cast stubs which are both broken.
@@AGEngineering It was never threaded. The stubs are part of the original casting, so would need boring out and threading, and then a spigot made to fit. Is it possible to attach photographs on this site?
In this case. Makes no difference, whatever your oversize tap is, can even be metric (cough..) I think it is mentioned in part 2, thanks for the comment, Ade
We used to build up the damaged thread with weld,bolt them to an angle plate,on a face plate, on the lathe. Single point screw cut them for standard size stubs. Taking even more material out of a casting that's already thin isn't the best way to do it, o/s stubs won't make it any stronger. Just saying. Crikey, just had a better look.The flimsy part of the retaining wall has got a hole drilled through. Be worth telling the owner of this cylinder head to be careful how they fit there exhaust system.
Looking good. If only I had known earlier you have customers for this service, I have the taps and a number of exhaust stubs, two sizes, to get rid of, shame you are the wrong end of the country. Probably all rusty as heck must dig them out and have a look,
Hi Chris, thanks for watching and the support. Large taps are always useful, let me know if you are interested in selling them, adegwilliam@gmail.com. Regards, Ade
@@AGEngineering I have a Bridgeport Interact4 cnc, no multitude of taps or drills or boring heads needed with cnc control. good channel, keep up the good work!
I'd love to delve into CNC but no room left for much else. I did watch some of your videos, useful kit! Ages ago I saw James Comstock thread mill on Norton heads and the inserts.I thought how do I do that with no CNC mill, hence the tapping, gets me out of a mess and I don't have to pay out a fortune. Thanks for the support, Ade.
@@crozwayne this is a center lathe job? Wants building up with weld and return to original size. It's already too thin. Angle plate on faceplate,in the lathe. Single point screw cut. Or if you want to be posh use a chacer.
Again, if you have a big enough lathe, if you can weld, if the person wants their head welding, some don't. I have done tiger cub heads on a lathe faceplate in the past by that method but that's about the limit for my lathe.
Loved it, cheers Aden, looking forward to part 2
Thanks Andy, I'll get to some more editing later in the week.

I would think so, do you know what the original thread size is?

Sorry, your response ended up in spam!
Are the thread forms Whitworth ?
In this case. Makes no difference, whatever your oversize tap is, can even be metric (cough..) I think it is mentioned in part 2, thanks for the comment, Ade
Why dont they make the stubs from brass , which has a very close thermal expansion to aluminum....and be done with it
May work, don't know, also risk of breaking with thin wall and vibration maybe? Thanks for watching, Ade

It's been on the bike for 2 1/2 years since it was done, so I think it'll be fine, thanks for your concern!
