Is this lathe worth buying for constructing small engines.

Jo:
The Proxon machines are well made but I wish their electronics are more reliable.

For the budget a Hobbymat MD65 would be a better buy ... Ask Roger, he has my old one  ;)


Just trying to remember when I used a small lathe to cut a thread  :noidea: Nope I use dies up to about 6mm/ 1/4" threads.

that's it though, even if i never used the screwcutting function i'd still need to purchase the high end model to have the expandability for milling machine functionality, extra bed length and extra horsepower. and i know even less about them than about a lathe. I know what a lathe looks like but i was never allowed use one in woodshop.

what advantage is a milling machine on a lathe over a standalone milling machine. it looks very wobbly as there's little support is it to allow you to cut channels for a woodruff key in a crankshaft.

Roger B:
If you have the space and money a stand alone milling machine is a better option. The combined machine allows you to use the lathe carriage and cross slide as milling slides. I have a combined machine due to lack of space.

Jasonb:
Although you may not have that much need to cut threads on a small lathe the big advantage of the 250 over the 150 is the fact it has a leadscrew which will also provide automatic feed which is a big advantage over hand feeding. The 150 does not have a leadscrew

If you want to make small IC engines then the ability to cut fine pitch threads of reasonable say 20mm diameter is also an advantage should the design have the cylinder screw into the crankcase

Nothing will be as good as a stand-alone milling machine but the rear column is going to be better than milling with a vertical slide and the cutter held in the lathe chuck. really comes down to your budget and available space.

steamer:
For my ONLY  lathe I would.buy the largest you can afford.    Buying new.lets you buy the accessories which are important.
