At $7K, why am I not surprised?

Hi, I'm a dedicated TurboCAD user and have been since V14. It cannot do all the things Solidworks can do but for 15% of the price, for its' top of the range package, it's pretty damn good. One thing I would say is if you want to use 3D modeling, whatever package you select there is a learning...

Your very welcome Herb and the coffee was great too. :D Best Regards Bob

Hi Herbie, Would you like me to pop in and give you a hand, I also have some castcraft rods. Just say the word and I'll come up, ( as long as the cofee's hot ;) Best Regards Bob

Hi Guys, Thanks for the support. :bow: Well its all welded together :D A couple of shots and one of the copper tubes, all 27 of them which I spent today cutting to length :o Best Regards Bob

Thanks Div 900, The major welding is now done but I'm not all that happy so, my pressure welding mates are going to fix it then I'll post some piccys. Best Regards Bob

The stays are done and now we are ready for welderama Best Regards Bob

Personally, I feel that castings are a model representation of the full sized machine be the design a scale down or freelance. So the castings where possible should be of the same metals as the full size engine type. Best Regards Bob

Hi Gene, Thanks for stopping by. My 3 in 1 is a Shillito C316 DC machine i.e. it won't weld aluminium and AC machines are big bucks plus this function is not important to me. Your tube expander sounds OK to me. I found some plans on the net and intend to make my own. Mine will be what is in...

Hi Guys, It's been a while but I have finally managed to weld all the bosses onto the shell using tig. Here are some piccys The dry pipe is ready for installation and then the serious business of the tube plates and furnace can commence. Best Regards Bob

Maybe try sweep or rail sweep with both twist and draft angle along a path between start and finish sections. Hope this helps and works for you. Best Regards Bob

The easy way to convert imperial to metric is to use 24mm = 1in. This gives a slightly smaller model in metric than the imperial original but most standard imperial sizes convert to standard metric sizes e.g. 1/4" = 6mm. Try it and you may be pleasantly surprised at the result. Best Regards Bob

Firstly, my apologies you are correct 0.7 and 0.8 mm pitches were missing but so are those below 0.35mm and those above 4mm. I have added those to a newly attached chart. As far as the feeds go, it would appear the basic difference between the half nuts and the feed gears is 1:3, i.e. 3mm on...

Maybe you should take another look. Best Regards Bob

Yes, it fell off the bench and I've been messing about with boilers and my daughters emergency fire pump, (she's at Kangarilla). Got the pump running, the recoil starter collapsed so they bought a new one. Now they have 2!! Still it's better than Zero:) Best Regards Bob
