I have just finished hand sanding the mast for the launch and have decided this scaled up to all of the masts and spars on the main kit is going to be a task and half.

I was interested in getting hold of a Proxxon DB250 lathe which I have seen advertised but checking the spec it says the working centres are a max of 220mm.

Would anyone know if this will give sufficient working length for the masts and spars on he Victory kit. I would hate to buy the unit only to find it is not suitable for the job required.

Thanks in advance for any help you can offer.

Kind regards

tony

Not sure but dont think a lathe would be suitable, only say this because my understanding is you have to have excess material you can cut off at the ends of the masts and yards. Dont think we will get excess material, i got someone i know to make an attachment for a drill that means i can support a yard from the centre and sand down, turn it around and do the other end. I could be wrong about lathe though.

Whilst the 'working length' of the Proxxon lathe is limited, the spindle/chuck/collets are all hollow and you could, with a little ingenuity, knock-up something to support longer workpieces at the exit point of the lathe.

It is actually quite a nice little lathe (and, if you buy the optional 3 and 4-jawed chucks - the machine itself is supplied with collets and a faceplate) find it to be quite a versatile little machine.

My only critique of it would be that there isn't a facilitly to swap the centering spindle with a small chuck (to hold drill bits). Apart from that, it's a good buy.

I bought mine on Tomick's recommendation and am happy with it.

Hi Shipmates! BigGrin

I obtained the Unimat 1 Classic and a 1000mm Machine Base, this gives me 6 machines.
A wood lathe, metal lathe, milling machine, jigsaw, sander and mini drill press,
The unit can be upgraded to make other tools even cutting gears.

Only just seen this topic, I would echo everything Capt Stedders has said. I to was recommended the Proxxon by Tomick, so we can blame him if things go wrong BigGrin BigGrin (Only joking Tom - honest!)

Because you can pass the dowel through the inside of the motor unit, you can work with quite long lengths. So far apart from practice pieces I have only just used it in anger on Sunday to shape up my windlass for the launch. It was a dream exercise without all of the hand shaping and sanding for just one component. A lot of money to layout because as well as the lathe you need a set of modelling size chisels but in my view well worth it and the possibilities that it offers.

Following up on what Andy said, I tried experimenting with some dowel clamped in a drill but it needed a support for the other end. Zeptrader showed his set up in an earlier post. My attempt was not very successful and when a piece of dowel spun away and narrowly missed my head I decided to go for the real thing.

I have just got an almost new Proxxon flat bed circular saw from E-bay and am looking forward to accurately cutting the planking when we get on to it.

Another very useful item for making light work of sanding is a Disc Sander, the Proxxon TG125/E has variable speed and a dust extraction feed.

here a tip if you have a 200mm sliding bed, pack the none wheel end out by 2mm tighten boath ends with locks you will taper your mast approx 6mm dia to 4mm over 120mm just by machine alone different beds different tapers same with different packers , the packers i use is just off cuts of wood 2x5 mm

Mike, i use an attachment for the drill which holds the dowel in the centre so you can sand one side then turn it around, so no clamping the side already sanded. Must admit i did not make this but i did draw it and someone i know made it. Its just a hollow tube that will fit into a dremel or drill. The 3 screws holding the dowel do not have to be tight so as long as you put tape around dowel centre they dont leave a mark.

I'm not knocking the idea Andy. The set up looks impressive.

My efforts with a drill were a bit tentative and I guess that at the back of my mind I wanted to get the wood turning lathe with variable speed and support at both ends of the dowel etc. and to extend my craft interests when I get the time to make other objects. (Time what's that?)

I would have quite liked to get the Unimat Willie but the extra cost at the time, took it beyond budget.

I like the idea of home made lathes...perhaps there are some amongst us avid modellers that can come up with ways that we can construct such necessary devices in our own homes, and not being able bodied myself and not being strapped for cash, I would appreciate some ideas on this..Blink

Thank's for the tip and from your pictures looks like a good way to taper the masts, the modular design of the Unimat 1
is Great! isn't it!

I noticed this at the weekend and forgot to post it - Sorry!

It looks a real bargain, the chisels alone cost almost £40.00 new. I wish it had been there when I bought my lathe!
