Hi

1kg hammer, have a look at the one Frost sells:

Or I am pretty sure Machine Mart on North Station Road would have one.

Cheers

I use a double ended Thor type hammer, aluminium insert one end and hard plastic the other. This seems to work well as I use the plastic end first and then give about four good whacks (technical term) with the ally side. This gets the spinner tight without damage. I think I bought it in B&Q.
I have tried rubber mallets before but personally I didn't feel they were too effective

Do I have to assume that the hammers are are certified as calibrated to obtain the correct 210 lbsf ft torque? :lol: :wink: :lol:

I use Sarto's excellent device: http://knockoffspinnertool.com/products

However, there is an alternative: http://www.spinitoff.com/

I've been using a copper/hide mallet from Axminster tools - about ?15 I think, they do 3 sizes, I went for the middle one.

If you are wanting to hit the spinners then a Lead or Copper mallett is best. The reason being when you hit with either lead or copper the strike is a dead blow and you dont get any recoil or bouncing back of the mallett. If you use rubber or hide you cant get as much force with each strike also more risk of recoiling and damaging body work etc.

I've also used a cabinetmaker's dead blow hammer. This tool uses a shot=filled head that absorbs the impact and reduces or eliminates bounceback.

The advantage is that it has a soft face since it's intended for use on wood and won't mar the spinners.. The disadvantage is that it's a bit more fragile than the metal ones and not quite as heavy.

I use the original lead hammer and a nice block of mahogany - works OK.

I have also been advised that automotive dead blow hammers as sold by Snap-On and others work well.

I like the idea of the posh Sarto Spin it Off type tools but there is always something more important to spend the money on :roll: - hopefully the wheels don't need to come off too often anyway.

Hey John,

that's what I call adding a bit of Class; "a nice block of mahogany". :)
Joking aside my ol' Dad used same for various jobs because it's a nice solid lump of wood well capable of transfering the "shock"

Cheers
