Hi Max & Norm,

Wow a few days away and you guys have placed some terrific info there. Thank you ever so much.

- RE: washers as spacers - good points (as always) Max - I will remove them. I knew it was a bit of a bodge effort but your points are all noted and I will take out.

- Excellent diagram with the spacer disc thats needed. Yes, it's a tricky one as needs as your diagram shows the protrusion/raised section to go into the blade carrier & then the indent/depressed section so it can allow the shaft to go into it.

- Yes, I've just looked online and as with you Max, cannot find anything of the shelf - not that I thought I would on the spacer front.

- Max, thank you for confirming that those D-hole shapes are easily enough fabricated with a dremel after drilling, I will order a few stones to keep onhand - much thanks.

- Norm, that is a very kind offer - and one that if you're open to being fairly paid, I'd quite likely take you up on. When i remove the washer spacers, I think the stepped blades will only give ~5mm of skirt vs cut differential. A decent amount more (`20mm) I'd say would be ideal. The added benefit of this would be I could go back to using the vastly superior hardened slasher blades, though I do suspect the fluting of the crappy Cox ones will assist with the clippings being thrown better - as opposed to being clumped as is the case now.

I'm pretty good with no hitting obstructions, but still mild steel loses it's edge very easily.

If you have a H660 there, I'd imagine your measurements will be superior to mine. I'll pop you a direct message, but please I do NOT want you to do it at cost, you need to be fairly paid as it will be a great help to me - happy to pay in advance and you can refund me what you don't end up charging (I offer this as I don't want even the perception of your goodwill being taken advantage of).

Cheers, Nick
