PPS industries bring in the best ones (Pferd) and they sell direct. You could also try Tradezone or Twiggs in Welly. 

I personally rate rolled cones way above the cylindrical versions. They last way longer as there’s loads of layers to get through and they’re smaller diameter, so won’t fly apart as easily.

Thanks, went to Twiggs in Welly today, the PPS website is rubbish. Twiggs is researching.

They are pricey suckers though

I just buy crappy ones off Ali, don't last fuck all (pretty shit lol), but they also cost fuck all, and I don't use them often.

eg https://www.aliexpress.com/item/102pcs-Set-Sanding-Drum-Polihsing-Bands-Sleeves-Grit-Pads-Set-Rotary-Tool-Rubber-Mandrel-Kit-fits/32858418308.html?spm=a2g0s.9042311.0.0.4bf94c4dtXvdrp

I just use them for tight spots, power sander for everything else. I also only use a battery die grinder, so smaller diameter shafts, puhuhu

They’ll be able to buy them through Saint Gibson Abrasives (Norton brand) and they shouldn’t be tooo silly on price.

One of the bolt holes that hold my starter in place is shagged. Should i attempt to retap with the same thread or drill out and step up a size? It's imperial thread so retapping the same means buying a set, stepping up I could do with my metric set. But, prefer to do it right...

Regarding taps. I've recently been buying German Volkel brand taps. From CarbideNZ. They are quite affordable for what I think are quality taps. Miles better/sharper at cutting threads than the absolute rubbish "Frost" brand set I have.

If you can fix the thread (by going bigger and metric) with a set you have, I'd go that way for sure. I can't see that fix not being up to the job anyway.

This is fleeting with danger of making future Mr bronzes life a worse place for the sake of a helicoil set

Having not the right spanner for putting metric/imperial bolts in opposite thread holes and other surprises lay down that path in the future
