Powder coating small parts: measure the oven before the gun
Updated: 21 October 2026
You are looking at a box of steel brackets, a lever, and a few bike bits, and a powder gun looks cheaper than another trip across town. Powder coating small parts is a home job only when every piece hangs inside an oven you already keep away from food, and when the local coater’s minimum for that colour is higher than the kit you would buy. Measure the cavity, then open the [powder coating gun comparison](/hub/painting-supplies/powder-coating-gun). Peter F. used Ritual Motorcycles’ 2024 trade ranges, Astrax, Coating.co.uk, and Eastwood’s cure note, and ran no lab coat. A qualifying purchase can earn a commission at no extra cost to you.

Parts that fit, and parts that do not
Brackets, levers, and battery boxes are the pieces a garage can finish. Ritual Motorcycles, writing for UK bike owners, treats a frame as a poor first home job because it is large and needs even heat, and treats those smaller parts as the practice that makes sense. A frame tube that sticks past the door stays cooler than the tube in the middle, so one end under-cures. Astrax’s cabinet of about 60 cm by 40 cm by 50 cm is one builder’s oven for bike parts, not a size to treat as normal.
Lay the longest bracket on the bench, then add the hook and a little air on every side. If that length already beats the shelf you have, the part is a shop job. A full-size wheel is the same check, and none of these amazon.co.uk listings states an oven’s internal size. Measure the cavity you already own. When the part will not hang inside it, the coater’s minimum is what decides the purchase.
What a UK coater is likely to charge
A one-off batch fee can beat a gun you will use twice. Ritual Motorcycles publishes approximate 2024 trade ranges, and those figures are that shop’s comparison, not a quote and not a national price. A small-parts batch there starts at about £25 to £50 per colour, fork lowers about £35 to £60, a wheel about £40 to £70, and a frame about £80 to £250.
Coating.co.uk builds a price from pretreatment, masking, shape, batch size, and powder type, and it gives no national figure for a bracket. It uses 0.5 kg of powder for about 4 m² of flat surface as a planning figure, which is their number. A handful of levers is a small slice of that area, so the powder is rarely the bill. If the minimum already sits under a gun, an oven, a compressor, and a bag of powder, sending the box away is cheaper for this job.
Masking and prep
Powder reaches conductive metal the cloud can find, including a thread you still need to turn. Ritual Motorcycles flags unmasked threads and bearing bores as the expensive mistake: a cured film stops the fastener, and it stops a bearing seating. Eastwood’s manual, on its own schedule, says the part has to withstand about 204°C, which is why plugs belong in the masking. Leave bare steel where the earth clamp bites.
Coating.co.uk lists pretreatment among the things a coater prices, so ask what they expect already stripped before you treat the minimum as the whole bill. Astrax’s note still applies at home: the cure gives off fume, so the cabinet is not a food oven. The spray order, recesses before the flats, sits on the how to powder coat at home page.
When a gun from this comparison is enough
The amazon.co.uk kits in this comparison run from about £94.92 to about £176.20, before the oven, the compressor, and the powder. One bracket against Ritual’s approximate £25 to £50 minimum does not pay for that kit. A winter of the same levers can pay its way, once a dedicated oven and dry air are already there. The best powder coating gun page sorts those listings only after the cavity and the minimum both say the job is yours.
Paid customer work moves the job under COSHH and DSEAR, and the Health and Safety Executive sets those duties out for employers. A favour for a neighbour is still your oven and your fume. A paid batch, a frame, or any part that will not hang in the cavity is the moment to use a coater.
Common questions
How big an oven do I need before I buy a gun?
You need a cavity the part can hang in, with the hook and a little air around it, before a gun is worth buying. No listing in this comparison states an internal oven size. Astrax built one cabinet of about 60 cm by 40 cm by 50 cm for bike parts, and that is one builder’s oven, not a size to copy. Measure the shelf you already have. Eastwood’s schedule cures at about 204°C in an oven you never use for food.
What does a coater charge for a small batch?
There is no single UK price for a bracket. Ritual Motorcycles publishes approximate 2024 ranges of about £25 to £50 per colour for a small-parts batch, about £35 to £60 for fork lowers, about £40 to £70 for a wheel, and about £80 to £250 for a frame. Those figures are that site’s comparison, not a quote for your town. Phone with the part in your hand and ask the minimum for one colour.
Why do threads and bearing faces need masking?
Powder coats the conductive metal it can reach, and a thread or a bearing bore is still metal. Ritual Motorcycles calls unmasked threads and bores the expensive mistake, because a cured film stops a fastener starting and stops a bearing seating. Eastwood’s manual puts the cure at about 204°C, which is why plugs are part of the job. Leave a separate bare patch for the earth clamp, so the charge has bare metal to bite.
Can I do a wheel or a frame in a domestic oven?
Only when the whole part hangs inside a dedicated oven and can reach the cure. A frame or a full-size wheel often cannot, which is why Ritual Motorcycles treats a frame as a poor first home job. Astrax’s cabinet of about 60 cm by 40 cm by 50 cm is one builder’s box, not evidence that your wheel fits. Treat a wheel as a volume test, then decide whether a gun belongs in the job.
Is one bracket worth a gun from about £95 to £176?
Usually no, when that bracket is the only job in front of you. The amazon.co.uk kits here run from about £94.92 to about £176.20 before the oven, the compressor, and the powder. Ritual’s approximate minimum of about £25 to £50 per colour can sit below that kit for one colour. A repeating pile of the same levers can tip the other way if a dedicated oven already exists. Ask the local coater before you buy.
