I have had pretty good luck making boots with a 3D printer using TPU filament. It took a few tries to get it right.

1/4-32 is probably going to be a problem. That is not a common size. 1/4-20 and 1/4-28 but not 1/4-32

Brian: What sequence do you use when making a connecting rod with a removable cap? If you drill the crank journal hole before you split it the hole is no longer round. Do you split it and bolt it together before you drill it? I generally just start out with two pieces of rod and cap and then...

The plans were in "The Shop Wisdom of Phillip Duclos" https://secure.villagepress.com/store/items/detail/item/819 I no longer have the engine I did make CAD drawing but they are copyrighted by Village Press

At this point you have two single cylinder engines mounted on a common base plate. You have separate carburetors, separate ignitions, separate cams. Engine #1 runs but engine #2 does not run so what is different about engine #2? Does engine #2 now have compression? Is engine #2 receiving spark...

So were your cams near the correct position prior to setting them up with the rotary table? From everything that you have said before it seems to me that incorrect cam position is the most likely problem. You have not been able to get compression in the same cylinder but putting pressure in that...

Brian: You have a heat treat/pottery oven. Just put the parts in the oven and heat them to red hot and then lower the temperature slowly until you get down to probably 500°

I am sure that the Canadian system has some problems but the US system has a lot of people not getting medical at all care because they cannot afford even the copay.

I am not experienced enough to determine what is causing the problem but I set acceleration from 400 to 300 and reprinted a part which had shifted and it printed with no shifting. I am presently printing the mating piece which is 40% done and it has not shifted. In the previous attempt it has...

I went to the old computer and duplicated all of the settings from the old computer without going to the older Cura version on the new computer. I also found the settings for acceleration on the menu on the printer. I was looking at the Cura settings on the computer and could not find a setting...

Recently I began having a problem with my "Y" axis slipping during printing. I have an ANET A8 printer and I am using Cura 5.6.0 slicer. I recently changed to a newer computer and the problem seems to have started about that time. The old computer was using Cura 5.3.0 and I found a discussion on...

Welcome from another Michigander on the other end of the age spectrum.

That is also the case with me. I made drawings my whole life and did not realize that there was 1st and 3rd projection until I retired and ran into drawing made "backwards". The first time it really confused me. I thought that the designer had screwed up.

I never realized that there was such a thing until I was working on a drawing that someone else had drawn and I could not understand how the piece was made. Everything was backwards to my thinking. Things that should have been shown with hidden lines were solid and solid lines were hidden. I...

A friend of mind delivers parts for the local Import Motors. They sell Volkswagen as well as Mercedes. He is always telling me about how something like a windshield for a for a Volkswagen will cost $150 and a windshield for a Mercedes will cost $800. These are probably both coming from the same...

We need more of that type of thing today on everything from charging ports on our electronics and electric cars to many other areas where standardization would not harm the product but simplify our life. I have often wondered why the automobile manufacturers could not standardize a lot of car...

Just a little humor on that specification. The US Standard railroad gauge (distance between rails) is 4 feet, 8.5 inches. That's an exceedingly odd number. Why was that gauge used? Because that's the way they built them in England, and the first US railroads were built by English...

I have made a distributor cap using the 3D printer. Seemed to be OK but I had other problems with that engine

That either means that you have too many leaks to build pressure or more likely that it takes more than the 20PSI to move the schrader valve in the compression tester.

I have two of them. I have one that my dad made in 1981 and one that I made in 2005. They both have an "L" on the side. Ground off the part of the "B" that did not look like an "L". It was the first engine that I made and also the first of two engines that my dad made. We both also made a...
