Stay as far away from round column as possible. Tilting head is handy for making angle cuts. Spindle is 3MT (morse taper) would be much better if it was R8 Max speed is a little low at 1600RPM Dave

I've been a Alibre user from day one when they rolled the program out. New name is dumb, but I guess we have to put up with it. Here is an engine and Zdrive that I hope to put a pair in a model tow boat. rendered in KeyShot. Dave

I am working on a steam engine for a stern wheeler that I need to build an engine bed for. It will have to be several pieces silver soldered together. Is there a way to harden brass plate and strip after silver soldering. Dave

I run Pro but yes on personal it was upgraded also. Dave

Chuck Have you updated to Alibre 2013 now named Geomagic design ( dumb name). It has lots of new stuff. Engine is looking real good. Dave

Brian Are you going to have problems with the spring when clutch is disengaged with relative motion between fixed and moving parts. Dave

Here is a web site for a couple of friends of mine here in the States that are big Rivett fans. If you can find the serial number there is a list of serial number dates. http://www.rivettlathe.com/ Dave

The machine you listed will only power feed or cut right hand threads from right to left. For power feed left to right or left hand threads you will need to do as lots of folks have done and make a mod to the lathe to reverse the lead screw in relation to the spindle. There are plans on the net...

If you make some chips and melt them with an oxy-act torch the zinc in brass will flash of and leave a white powder behind. Stay away from the fumes they are not good for you. Bronze will just melt the tin in it will not flash. Dave

A couple of observations. 1 I have never seen a 4 jaw chuck with 2 piece jaws. 2 I have never seen a 4 jaw chuck with 2 sets of jaws. 1 set can be reversed so no need for 2 sets. For 129 $ I would not expect much in the quality of this chuck. I have bought from Shars and received what I...

At 195.00 per 25' roll someone needs to buy a roll and cut it into 12" squares for resell to the hobby machinist. Dave

There is no reason other than I could of done things differently. This was a learning process for me. Dave

Just yesterday my cnc mill spent 4 hours machining these little side plates for a donkey winch I am building. I did all the internal pockets first. then did a fake tool change so I could put the 4 screws in before doing the final outside profile. Left 2 tabs on the bottom of each plate that were...

I'm sorry. that is related to the program Gwizard when you are using it to get the best feed and speed for the job you are working on. Are you machining with CNC or manual machines. Dave

Nick New question. Can your method for casting be used for bronze and cast iron castings also. Have you ever measured the amount of vacuum you are pulling on the chamber. Dave

One trouble with tables is they have no flexability.One of the big killers of end mills is deflection. You can see what your deflection number is and if it goes beyond recommended it turns red so you can adjust your numbers. Dave

Every casting that Gary has cast goes to heat treat before it is sold. I have taken his pattern making class and had a couple of casting made from the patterns I made. Gary is a good teacher and willing to share how patterns are built so you get good castings from them. For any one in the...

I use Gwizard at www.cnccookbook.com It is not free but it is very good. Dave

Auzzie53 I have a copy of draftsight. Can you tell me how I can get it to tell me how long the line I am drawing is. Other CAD programs I use have a read out of some sort tht tells me now long the line is as I draw it. I like drawing to the grid Dave

You ask for examples. Here is an assembly of parts in Alibre. If you grab ahold of the shaft and rotate it the piston will move in the cylinder and the valve will cover and uncover steam ports. You can check for interference and correct travel. It would take a lot more work to do this in 2D...
