I finally finished this project after about 1-1/2 years of spare time work. I ended up with just over 1000 CAD/CAM files using SolidWorks and Sprutcam for my Series 1 PCNC and 9x20 lathe. There are...

Sorry - posted to wrong thread - forum won't let me delete.

I'm still heavily involved with this project and have just made another part on my Tormach that might be of interest to the group. It is 3-D impeller:

Another Radial - this time 18 Cylinders -...

I discovered something interesting about Sprutcam last night. It involves using the 2-D contouring operation on a curve. I cut two identical parts which were cam profiles about 3" in diameter using...

Jim,

I started a new engine project about 600 shop hours ago. Here is a link to a build thread that I doing for it.

I have one of the earliest Series 1 machines. I added a 150 lb air spring to mine several years ago to prevent the head from falling. There are some photos of what I did, including some other mods,...

I'm close (I hope) to finishing a 9 cylinder radial engine that I've been working on for 1-1/2 years. I started a build thread on the Home Model Engine Machinist forum at:

Polycarbonate will quickly fog and then eventually craze if it is exposed to alcohol. I had to learn this twice. The first was when I treated my brand new $400 motorcycle windscreen with Rainex. The...

I used to see this same workpiece anomally in the simulation mode quite a bit. I found that changing the simulation method to Voxel 5D usually fixes it fo me. -Terry

The stuff I use is Devcon 5 minute Epoxy Gel available from Lowe's. I actually let it set up 3-4 hours before machining. The usual disclaimers about thoroughly cleaning any off oil (I use Simple...

The one that I'm using is their prototype. They asked me back in late November to use and abuse it after they completed their own testing in order to get some user input since I run my original...

I've been using the new version of Tormach's Speeder for about a month now and have been very impressed with it. Compared with the original version it still has a 3:1 speed multiplier, but there have...

Hi,
Go to your machine parameters tab and make sure under control parameters you have "Use arcs" checked , "Use arcs in XY plane" checked, and verify the parameters for minimal and maximum arc...

Mike,
You would just have to try it. The 60 deg blade sticks out about 1/8" past the holder, but my measurement of the length of the cutting edge of the blade is about .050". You will likely be...

Here are some photos of the intake/exhaust gaskets I just finished for my 9 cylinder radial engine. The material is 1/32" fiber gasket material from a local auto parts store. I used the Sprutcam...

It might be your belt. My pulley has a bit of run-out and every year or so, I'll need to grind down the area on my belt near the splice - even on a brand new Gates belt. Over time the belt seems to...

I might be wrong about this (flame suit on) but I don't think you can pull the armature out of a stepper, make a repair, and then replace it without the proper equipment for re-magnetizing the...

I've been seeing this problem on and off for years. What happens is that on some letters in some certain sizes for some particular fonts the curve-end flag needs to be moved manually to get the...

Fred,
I use that color-coded machining result compare all the time - it is very useful. But on this particular issue it did not show the gouge. I received a reply from U.K. Dave ( UK Sprutcam...

OK, here is the project which gouges the part. Creating a fixture by extruding the lobe profile curve eliminates the problem. I've also since found that checking the strategy box "check workpiece"...

I was making a steel cam the other day which is a disk about 3" in diameter and about 3/8" thick with four cam lobes around the outer periphery. I decided to use the 2D contouring op as it is pretty...

Dave,
I bought a fuel pump at at hobby store used for pumping fuel from a container to the fuel tank on a model airplane. I removed its housing leaving a 6V dc motor coupled to a fuel proof...

Dave,
I used the TIM6 also on this. It fact it uses two of them. The faux transmission housing just hides the big out-of-scale ignition coils and the fuel tank. I put a pair of belts driving a...

Dave,
The V4 was actually my second engine. Jerry's V-twin was my first. Here is a link to it running:

Sage,
This is what I came up with:
intake start to open = 12 deg ATDC (actual lobe)

Sage,
I think there is an error in the design of the cam lobes for this engine. I
carefully checked the timing of all my cylinders with a degree wheel and
found that there is no overlap...
