Hello everyone! The spark plug store is officially open. A few years ago I purchased all of Dale Detrich's stock and parts to make his side fire plugs. I have also made 3 of my own design with the standard ground strap design. I have in stock . . 6-56 8-40 10-40 1/4-32 If interested you can contact me by phone but email is better because I still work 70 hrs a week. To see what I have to offer you can go to www.miniaturesparkplugs.com. To order contact me at stevehuckss396@gmail.com or call but you might catch me at work. With NAMES coming up I can't officially sell plugs at the show but if you want to save a few on shipping you can purchase and then pick them up from me there. Just look for the giant sparkplug. Thank you.
Those sure are nice. If I can successfully get through my glow engine build I hope to graduate to a spark one day!
Very nice Steve! with many model engineering companies falling by the wayside, its nice to see an offering such as yours. Good luck! John
Just want to let everyone know that I have had a few reports about the threads on my plugs being a little tight. I check every base with a go-no go gage set to be sure they are correctly sized. The trouble might be from cheap taps. If you run into that trouble try buying a good quality tap made in the USA, Poland, Japan, or Germany. As they can be expensive and may only be used a few times, or you already purchased the cheaper tap, try bumping up the tap drill one size and see if that eases the fit. I have found some good taps in 6-56 (Japan) and 1/4-32 (USA). They are available on the website. I have my eyes pealed for 8 and 10 - 40. If I can find them for a reasonable price I will get them up also.
No issues here with #10-40 plugs, Steve. I think the taps I have were made by Widia. I forget whether I got them from Travers, MSC, or McMaster. Just for giggles, I will put the thread mic to the latest ones I bought.
I received 8 each #10-40 plugs from Steve yesterday and measured them with my thread mic. They all came in below nominal max pitch diameter and were mostly at the top end of 2A tolerances.
