Any comments or advice gents?

08/01/2012 16:41:33

This is my SIEG SC4 tool post parting off blade holder. I haven't used this yet and am looking for a blade. The slot is 14.2mm and when the clamp is tightened it closes to 13.2mm. So it will not clamp a 1/2" tool and a 5/8" tool is too large?? I am assuming that the parting off blade fits directly into the holder? does it need to be packed to clamp a 1/2" tool" Should I mill out the slot to fit a 5/8 blade? I would be interested to hear if anybody else has had this issue, and how you have resolved it.

Thanks

Any advice or contacts for companies that are happy to sell the small amounts of metal that a novice model engineer might need in the Yeovil / Somerset area?

Thanks

Thread: vertical slide or x1 mill attachment

02/01/2012 11:18:53

Thanks for all the comments, I have bought a vertical slide and vice from Chronos., which arrived in a couple of days, despite the holidays. To my inexpert eye it seems a solid piece of kit. To fit my SIEG , I've had to reduce the diameter of a couple of pegs that fit into the t nut slots on the cross slide and modify the T nuts. As I progress with using this I may well find some limitations to its capability, and perhaps initial limitations in funds may have influenced my decision. Overall initial impressions are good, but have noted Steve's comments on the 0.5mm divs in the traverse wheel. I was thinking about building a simple hot air engine, but reading the comments on the forum regarding these is this wise??

Francis, Steve

Thanks for your comments. I have gone down the route of a Milling slide wirh a double swivel. Reasons:

I think that this will always be useful, even when I opt for a dedicated mill at some stage.

Less expensive, so some free cash for some more bits.

Although I'm really pleased with the performance of my SC4 lathe, I think the X1 bolt on would be a dissapointment and perhaps soon out grown. I'll start to fill the piggy bank for a higher spec machine once I've out grown the slide.

Regards

Bob..

Hi Francis and thanks for your reply and comments. I'm getting into automata models, which started as toys for nephews and soon to be grandchild. These have started as wood constructions, but I'm keen to move the complexity of these forward, and and have been using my lathe to make some small detailed wooden and metal parts. I hope to make some basic gear and drive mechanisms, at present nothing too large, and quite basic as I gather tooling and expertise. I had a look at the X1 in the site and have now perhaps added a 3rd option to the equation!

Following in the spirit of the "no question too stupid", it must be easier to set up work pieces in the horizontal rather than the vertical plane.??

Morning.. First post so please be patient.

I have a SIEG SC4 lathe and I'm sat here tying to decide should I buy a vertical slide or an X1 mill attachment?? Comments and experience would be most welcome.

Thanks

Bob
