Router Lathe WIP

[Walney Col]

I've just started putting a small diy router lathe together from a set of plans I drew up in sketcup if anyone's interested in seeing few photos of the build.

With a bit of luck I should be able to show you how in a couple of weeks Brian.

How are you planning on cutting the gears ?

 

[Walney Col]

I cut the gears on my bandsaw. A couple of them are 48mm thick (4 layers of 12mm ply) but most of them are only 24mm thick.

this shows up a problem with sketchup, I have a 32 bit machine and all of the later drawings are for 64 bit, they will not load. Nothing lost in this instance just a quirk of sketchup that is a PITA.

 

[Terry - Somerset]

Possibly a bit of a cheat but I have always wondered whether bicycle sprocket sets and chain would provide a quicker more precise solution - wood gears would need cutting with quite high precision.

Would need an idler wheel to take up any chain slack depending on ratio selected and forward/reverse. Also need to do some sums to see whether one could get the range of ratios required.

I wasn't aware of that or I might well have stuk with 32 bit. As you say that's a right pain. Sorry!

I enjoy working with wodden gears anyway but I looked at cycle sprockets when I started and couldn't find anything inexpensive that would have given me the required 20mm to 400mm range change.

It did eventually load so no worries maybe just a glitch on my system.

The job they are employed for in this instance wooden gears are plenty accurate enough. Cutting them is quite theraputic and quick compared to cutting metal gears which I do regularly. a sketchup print out glued to the wood makes it a simple task. It is one of the great things about sketchup. I should really get into it one of these days. The trouble is I seldom draw anything and work direct from my head, hee hee.

Will be following this build with interest – I downloaded the Shopnotes router lathe plans, but this looks better! Will download your Sketchup file later.
A router lathe is definitely on my to-do list (not really sure I need one, but I find them fascinating)

I started working on my own plans after having bought the shopnotes ones. For me not being able to choose what direction the spiral goes in made it a non-starter but while messing about with that I also added a wider gear range plus profiling/copying capability and I have quite high hopes of it. Funny you should mention not being sure you have a use for one because my only real interest in tables (or any other furniture for that matter) is in making the machine itself. :-/

Hi Col,

Just wondering where you sourced or are going to source the lead screw?

Cheers
Simon

 

[Walney Col]

I got the 20mm acme leadscrew (plus a nut for it) from the seller UKBOLT on ebay.

Cheers for that. A lot cheaper than the imperial ones I was looking at for the Shopsmith plan.

Cheers

I've finished enough parts to start assembling it now so I've made a 10 minute video just to let folks know that progress IS actually being made!

Excellent stuff Colin - watching this with interest!

Part 2 of the router lathe build is now ready to watch and deals with determining the locations for the gear mounting holes on the gear carrier.
