                                                                      Bespoke Blasting Service

                                                                      We now provide a specialist bed, soda and grit blasting service for engine, gearbox and cycle parts. This has stemmed from our engine rebuilding service where we needed a specific finish for different parts of the machine. It was difficult to find a company that understood the correct finish on classic machinery and also would properly mask and clean the parts resulting in a lot of extra work for us.

                                                                      Last year we decided to do it in house and six months on we are now happy with the results, our work has been used on some very nice restorations and custom bikes so we are now offering blasting as a service to our customers in the UK.

                                                                      We blast each part individually with care in a small plant not in a big industrial tank with a lot of other parts so we can get the best possible finish.

                                                                      We use three mediums for blasting depending on the material and of the finish required, sometimes a mixture of media is needed to get the correct result but broadly speaking they are:

                                                                      Soda - this is an ideal non-eroding media for aluminum alloy crankcases, engine covers and any aluminium/magnesium alloy part that will be polished also the only media to use safely on castings with complex oilways (such as a lot of classic Japanese engines).

                                                                      Bead - still the best media for British bike cylinder heads, a light bead blast after soda blasting gives cylinder heads a really good "like new" even, satin finish. Can be useful on some smaller cycle parts too using a larger bead at higher pressure gives a good "key" for painting.

                                                                      Aluminium oxide grit - the best media for cast iron & heavier steel parts such as some wheel hubs, cylinder barrels etc. It gives a good deep key for painting.

                                                                      Some recent examples:

                                                                      Here's a Triumph head we did for a customer using soda then a light bead, very pleased with the finish.


                                                                      Here's some heads from a Kawasaki triple we did for a customer, even though the heads didn't look too bad initially you can see the one on the left now looks like a new part.

                                                                      We operate using a courier return service (UPS) so you can courier us the parts and we will process them and return them to you by a secure service which is trackable. If you are local to us you are welcome to drop them off and collect them but please arrange this with us as we work on other parts of the site and also run a busy mail order parts operation.

                                                                      Please email us with your requirements and we will be happy to quote you and advise on the best media for the job. We ask that parts are fully dismantled and degreased before sending, we will mask off components before blasting and thoroughly clean them before returning them to you.

                                                                      You can contact us at our usual email
