“I want to say a big thank you to Andy & his team for balancing my Formula Vee engine parts.

I dropped the parts off in Slough and was surprised about Andy’s knowledge regarding high performance aircooled engines. He is one of those people who gives the time for the customer to explain their needs.

He quoted me 2 weeks to get the job done but received the phone call after 1 week to my surprise. Usually when you drop off something to get work done you have to chase people.

The work was reasonably priced and good value for money compared to what some other companies were charging. HT Howard are my preferred shop for engine machining work!”


Classic Mini Engine Machining Testimonial

It is always satisfying to receive a written testimonial from a valued customer. Alan Godfrey kindly wrote the following with permission to share:

Alan Godfrey - Jan 2021 - Mini Engine Machining“When rebuilding the engine on my Classic Mini I discovered that the inside of the cylinder was badly scored as a result of a gudgeon pin coming loose at some point in the engine’s life. Knowing that the cylinder needed re-boring, I contacted HT Howard via their enquiry form on their website and received a swift and detailed response to my enquiry. Andy was very knowledgeable about the problem which gave me the confidence that he was able to carry out the work. He discussed the range of options available, which helped me decide on the best course of action.

The following work was carried out: cylinder block was bored (+0.040″), rods balanced, new pistons ordered, pistons fitted to con-rods, piston rings installed and all parts cleaned ready to be refitted. When it came to the bill, all work carried out was clearly itemised so I could see what I was paying for and paying by bank transfer was very convenient.

Throughout the repair, Andy kept me updated on the phone and was prompt with answering my emails. HT Howard was also very strict with following Covid safe procedures that needed to be followed at the time (Jan 2021) which further demonstrated their professionalism.

HT Howard is highly recommended to anyone who is in need of a knowledgeable and professional engineer to work on their beloved engine.”
