Hi Rob,

I'm using Vectric Cut2d CAM software. It was reasonably priced but has some limitations. I do a roughing cut first with say a 2mm slot drill. For roughing I lie to Cut2d telling it that I'm using a 2.2mm cutter so it cuts just clear of the desired profile. Then I do a finishing cut telling Cut 2d that I'm using the actual 2mm dia cutter. The results have been very pleasing.

I've been considering CNCing the wheels but will need some 3d CAM software - any recommendations? Cut3d would be OK I guess but it's another £200 or so.



Hope the explanation on the height setter I gave to Eric helps. If not, just ask.

Thanks for encouraging me to post something. (And to Craynerd.)

Hi Phil, it is about time you posted this absolute beast of a machine on here. Puts my poor efforts to shame but it is generated enough inspiration for me to get my arse in gear and give cnc a go   :headbang:  Thanks for posting Phil, amazing machine.

PS. does the little height setting guage come apart?

Hi Phil

I thought it may have been  a Vectric product when i noticed the TABs  on your loco parts , Thats the thing with good 3D software its not cheap ,i have looked at the Vectric software  (watched the training videos) it dose look good value for  the money and product support.

I don't no witch loco your building , but i bet buying  wheel castings would cost at least half the cost of the software .  :med:

Hi Chris,
 
Yes, the height setter does come apart. The bottom part of the contact is held on to the 1/4" dia post with an M3 countersunk screw.

I'll show you tomorrow.

Cheers.

Phil.

Hi Rob,

I'm building a LION. (Used for the Titfield Thunderbolt in the 1953 film). A mate of mine bought the LBSC drawings and is busy doing 3d CAD models of all the parts. I'm therefore making 2 sets of everything I can on the CNC. The wheels are only available in 3 1/2" from one supplier and for two sets they'd be about £200 - you were bob on when you said that a set would cost half the cost of the software.  :thumbup:

LION is the worlds oldest surviving Loco having been built in 1838. It's at the new Museum of Liverpool. The model we're building should look like it did in 1838 not like it does now or how it did in the Titfield Thunderbolt.

Cheers.

Phil.
