No rush but consider me applying as guinea pig! I have two axles ready to test.

Tag - you are it. No promises but I'll try to get one made this weekend.

I still have the first prototype I can send you. I had intended to send it back to dan. All it needs is new nuts.

What ever you want to do Brian but I was planning on adding countersinks for the nuts so it would work on the shorter studs.

Her ya go piggy. I told you it never hurts to rattle my cage spinning smiley sticking its tongue out

I need to get a forcing screw and then it will be ready for testing. That 1-7/8-8 internal thread went easier than I expected and fits like a glove.

Hi, new to this subject but have hub problems on a 72 spitfire. I would like to buy an appropriate puller. Located north of Winchester. Could pick it up.

Exactly what I have been looking for - another guinea pig with a different car thumbs up I'll need the dimensions for the Spitfire hub. I'm retired and home most days - if you are up this way visitors are always welcome. Give me a call or drop me an email.

Great to hear from you so soon. I have attached 2 photos and a rough drawing of the hub. Thanks.

Looks good but I need to know a few more dimensions:

  1. The distance from the face of the flange to the end of the axle.
  2. Diameter of the lug bolts
  3. Diameter and height of the shoulder at the base of the bolts

Are you good with a Spitfire specific puller like the one below or would you like a more "universal" design that will work on other models (e.g. TR's).

Here is my Spitfire/Herald hub puller.

The extra holes are for pulling ride on lawnmower wheels (check out You Tube, they can be a real bugger)

The depth measurement is to the captive nut.

Stock Spitfire studs are 3/8", my puller holes are oversize.

Had a chance to do a little more experimenting. This is M86A V2.0. It's made as two pieces which are then pressed together to make the complete puller. That means less metal to remove and cheaper to make. When I started on it my intention was to make it "universal" - i.e. it would work on Spitfires in addition to TR's. Unfortunately the geometry is really messy and I would be pushing by luck if I were to try and add holes for the smaller bolt circle. The holes themselves are not the problem - it's clearance for the nuts. It is not impossible but it probably won't be "pretty. Does anybody think it would be worthwhile as opposed to simply making a Spitfire specific version? I could go with a thicker flange which would solve most of the geometry problems but that would add $20 to the cost.
