I have made a few changes to the 3PI schematic and have uploaded the latest changes here. If anyone wants to make their own 3PI module, I freely permit using this design for personal use. If you don't have the will or resources to make your own from scratch, I plan on making a PCB for it...

Hello All. Please see the attached schematic for a new 3-mode small engine ignition module I have developed. Running on 6-9 volts, this circuit is based on the 555 Timer which allows precise energizing of the coil. It supports three modes 1) single shot with timeout, 2) buzz with timeout, and...

This is the new Dynatec style coil from China. The primary input winding is 1.5 to 2 ohms, and the secondary winding can output 30,000+ volts, producing a very robust spark using minimal battery consumption. Mass-produced coils with a primary winding in the 1-2 ohm range have been difficult...

Dad purchased this Fuller & Johnson casting in 1993 for $350. I've been told it's probably worth $550 now. It's been sitting around for almost 25 years collecting dust and now has a little surface rust. I have the most rusty side of each part exposed in the photo, so the back sides of each...

Yes - it is still available.

FOR SALE: Rider Compression Hot-Air Pumping Engine Casting Kit The prototype engines were made by the DeLamater Iron Works of New York City during the late 1800's and early 1900's. They were used for pumping water in country estate homes, on ranches, railroads, greenhouses and other...

For anyone interested, I saw this on eBay: http://www.ebay.com/itm/Home-Machinist-Engine-Casting-Kits-Free-Shipping-/221353337868?

As a seller of model engine plans, I was somewhat surprised how many very competent machinist are somewhat intimidated by IC engine ignition systems. Like many things in life, once understood, they are rather simple. To assist our electronically-impaired friends, I have launched a new site...

Not a problem. We ship worldwide. Australia is our largest overseas customer!

I don't think Dad had many customer issues with them, he just grew weary of making the boards. Mom still talks about how he used the toxic chemicals in the kitchen sink to clean them, then he had to drill all those holes manually. He'd rather be working on a new engine rather than "assembly...

Going through an old box of Dad's (Jerry Howell) stuff last week, I found 13 of the old buzzcoil ignition kits he used to offer. He was probably saving them for the dozen casting kits he never had a chance to put together. I'll keep three, so I have 10 to sell. These are now available from...

Here's another set of castings Dad (Jerry Howell) bought but didn't get a chance to start. It appears to be a casting kit of the major parts for a 1/12th scale model of a 12 HP Beam Engine by R. Sanderson, Glasgow England (Scotland?) circa 1846. The casting flywheel is 9-3/4" diameter...

Dad owned this kit, and was going to build it "someday", which unfortunately, never arrived. It's been sitting in the barn for two years and has started to get some minor/trivial surface rust, so it needs a new home now. Details posted on the www.model-engine-plans.com, Forum, Buy/Sell/Trade...

Maury, My father, Jerry Howell, passed away two years ago and he had about a dozen engine casting sets that he wanted to build "someday". Unfortunately, "someday" never arrived. I am now tasked with trying to find the value of these engine castings. I see in this forum you built the Novo hit &...

Yes, I definitely will do some shows in the future. I am hoping to do the N.A.M.E.S. show in Detroit this year, and maybe Cabin Fever next Jan. With having a regular full-time job and other projects, sometimes it's just hard to find time for everything! Thanks ALL for the encouraging feedback...

We have deployed the new web site for Jerry's plans and projects. www.model-engine-plans.com As you may (or may not) know, Dad designed and built his web site www.jerry-howell.com from scratch with no professional help. He launched his site in 1997, back when the the internet was still new to...

Tin Falcon, I just don't have the patience to work and machine small parts. I like to build larger things like boats, houses and outbuildings! However, my son has an interest in this hobby, so hopefully he can assist me and carry the torch started by Dad someday. Yes, I do want to attend some...

Greetings all machinist/hobbyist, We have added a user forum to Dad's web site. The link is near the top of the home page. It is our hope that it will enhance your experience with the engines/projects that were designed by Dad. As you may/may not know, Jerry passed away in late August '09 quite...
