HA - Repair and Re-polish Service

Repair and Re-polish Service


Hedgehog Armoury provides a premium armour repair and re-polish service. After five minutes of instruction (likely another blog post later) I can point you out what to get at Bunnings and you can do a beginners level job.

Pricing is dived into two models-


Set Price: Set price is designed to be the most expensive option. I will say a number, after I imagine everything that could go wrong, and cost it off those numbers.

Line of credit (open and closed limit): You advise which types of repairs and which level of polish you want, and then advise at which point you want your line of credit to stop, or advise to go until it is done.

Repair

An assessment of the armour will be made, and an estimate of what needs to be done will be made. Possible activities: Remove dints; re-strap; remove and replace rivets; re-articulate.

Re-polish

Even estimating the cost of a re-polish needs a physical inspection, and can sometimes need the start of the process to see through rust to see if the armour will ever be usable again. Significant damage to the surface can mean armour will never return to it's original condition.

The client needs to determine how many processes are used, which will determine cost.

Wirebrush only: Cheap and very nasty: The only thing going for it is that it is fast and cheap. It gets a low stain finish at best, and actually damages the metal and almost ensures more rust sooner rather than later. Not even a good paint preparation as the scouring pits rust underneath the paint surface, so it does that badly...

Black rouge only: inexpensive, slightly protective, low visual appeal. The black rouge can be quickly applied with the wheel and will cover the surface and protect from rust a small amount. The dull dark semi buff looks quite 'military' but not pretty.







New Armour - What is full polishing?

Current as of Jan 2017.
Hedgehog Armoury full polish starts after planishing is finished.
40 grit belts are used all over the piece. At this point, areas that need more planishing can be attended to, and the 40 belt repeated.
After this, I work through the belts in order 40, 80, 120, 160 grit.
Then come the wheels. These wheels are 40, 80, 220 and 400 grit.
Why the overlap? The 40 grit wheel must undo some of the work of the 160 grit? Yes it does, but wheels can get into areas unreachable by the belts, so we go a little backwards in the hard to reach areas in order to go forward.
Mild steel then receives the grey compound, then the white compound, then the bare fluff wheel.
Since 2016 have also used a product called “Liquid metal polish” with a mop afterwards for a final pass.
