I decided to tap the shaft for a 6mm bolt and use a 6mmx1.0x110mm bolt from Bolt Depot. They do not carry 5mm bolts that long. Thank you BP Hobbies but your 5mm bolts are too short. I will let everyone know how things work out. This Don Brown 5'' P51 spinner needs a bolt about 4.25'' long. Bolt Depot on the InterNet has a great assortment of hardware and does not require a minimum order.
Thanks everyone, P51Tom
I don't know for sure, but I thought that I read on here somewhere that the shafts on these motors have been heat treated and hardened, so it might be pretty tough going to drill and tap. Just a thought. I could be wrong.
I would like to know how it works out for you.
