ShopShoe - Thanks for all your comments. I do enjoy designing and building my own ideas. It's easier than following the plans of others because I can make mine up as I go along. It is especially rewarding when you can make them work!

Mark T - Glad you like it and I will post a build video and final photos when it's painted.

Mark R. Jonkman - Thanks, the castings generally turned out well, but I did have to fix a few things. In the past, I would have redone the castings until perfect but I ran out energy to do any more pours. Flasks full of sand get heavy quick! I am painting these castings for a change of pace and...

pickleford75 Thanks for your comment. You are probably correct about the buzz sound coming from the coil. It really helps with the idea that it is a hit & miss engine, but then it really is.

Hello everyone, it has been sometime since I was on this site. There several reasons, mainly it has be due much reduced time spent in the shop. I retired 5 yrs ago and almost at the same time was diagnosed to have Multiple Sclerosis. At first, the symptoms progressed fairly slowly so I was...

Hello, Here are a couple of video I have recently posted on Youtube concerning tool modifications. The first highlights mods I have done to my Harbor Freight 4X6 band saw through the years to improve it's utility and ease of use. Most of these are my version of several mods accumulated from...

pkastagehand Thanks. The chip sure keeps the mess under control. I was going to make one till I found this on Amazon: http://www.amazon.com/gp/product/B000RYPHRK/?tag=skimlinks_replacement-20 Fits perfectly and I don't think I could buy the material and beat it into shape and have tuen out...

Here is short video of modifications and improvements I have made over the years to my horizontal band saw. Most were gleaned from various places on the net. The changes have made the saw I bought 15+ years ago that was barely adequate into a very functional tool that is pleasure to use...

Davo J: That's how I learned what I know about foundry work by following other threads and sites on casting, especially from this guy: http://www.youtube.com/user/myfordboy Have you tried Amazon for thr Irwin tap adapters. They have a desent price, though I don't know if they are...

gus: I think I understand what your asking. I think you mean the sprue and risers plus the flash at the parting line. As you can see from the photo below, I had very little flash and the gates were kind of thin: This being an aluminum casting, I just use my 4X6 metal band saw in the...

rrnutsplitter: Welcome. I just returned to posting on this site myself. Multiple Sclerosis - ain't it a drag! I was diagnosed with MS myself last August. It was causing me to stay out of shop, but now I've determined that you just have keep plugging along as much as you can for as long as...

Wizard69: I had the issue of finding material when started my foundry. I discovered the local pottery supplies shop had the following: sodium silicate, bentonite clay, very fine silica sand, fire brick and castable refractory used in kiln repair. If there are any near you should check them out.

Wizard69: Thanks - Hey that is a good idea. Made me think of other uses, like a hand reaming guide,staking as you suggested, or low speed sensitive drilling. Luc: It maybe the only time I'll have a use for the R8 to morse taper adapter that came with my mill! Brian: Thanks - Did you watch the...

Very nice! I like the "contemplating" folding chair in one of the shots, I had one of those when I built my shop.

This looks very interesting for an IC engine I hope to build soon. I wish I understood electronic schematics better and knew how to build a circuit!:p I'll follow this and see if I can figure it out! Al

To continue on. I drilled a cross hole for a removable T handle and to attach upper piece to allow installation and removal. A bolt is shown here, but it will be pinned. The T handle is removable by screwing off one of the knobs. The knobs scavenged from leftover hydraulic valve...

Beagles: Thanks for your great comment. I hope I am contributing to the forum after all the wonderful projects I have viewed and learned from on this site. Ian: Thanks, I'll have to post some other casting projects I have done.

I agree with those said it before - beautiful engine! Al

I test mounted the arm on the drill press - hey I must have measured ok because if fit perfectly. I machined up a brass bushing for the small end and test fitted a piece of ¾ shaft. I set up to cut the taper on the shaft by chucking the morse taper drill chuck adapter I knocked out of...

MachineTom: I thought about doing it that way, but the way I did it I had the parts bolt securely together and got a perfectly round hole. No chatter or interrupted cutting. Slitting it afterword was easy. Wizard69: Thanks for the comment. If you notice in the above pictures, I drilled out...
