Can you guess?

[21William]

What it is yet?



There is quite a lot of work on this one so progress could be slow!

 

[Pierre]

Its going to grip something but what the thing is, is as yet uncertain.

 

[fortress]

It’s a twenty first century metronome. :wink::wink:

 

[Penpal]

The thot plickens.

Peter.

 

[Dalboy]

I have one in wood

 

[21William]

Yes spot on Dalboy. Not too difficult a guess though as I was asking about them recently.

Using a small Router beware gripping it over the air flowing through the unit. I noted the air is driven through at high speed making the collection of sawdust and shavings useless,so I made an end cap over the cutter end to divert the air horizontally allowing me to collect quite a lot of dust and shavings from the Router cutter.I use a variable speed Router as well William.

Kind regards Peter.

Something to do with tool holding. Not sure if I'm on the right route(r)

 

[21William]

Yes sorry, should have said. It’s a router jig for use on the lathe.

Thanks very much for the comments Peter, I’ll bear it in mind.

I’ve ordered this router for the jig:

101748 KATSU Wood Trimmer Laminator 220V – Aimtools

 

[wm460]

nicely made, looking forwards to seeing finished results.

 

[21William]

I had a bit of a false start on this job so I’ve been waiting from parts and some bits are coming from China.

So to recap. Some 4” X 2” 3/16” Alloy Channel and a 65mm motor mount.

 

[21William]

Motor mount cut down and machined.

 

[21William]

Checking channel layout for slots.

 

[21William]

Bit more done.

 

[21William]

In spite of drilling the mount holes through the slots to ensure they line up I still need to open the slots a bit more. Job for another day.

Time to show the overall view when built mate ,may have some thoughts that would avoid a couple of steps. You must be working to a plan.I will send you full detail when this happens re cooling and using vents,my diversion method if it is appropriate that has revolutionised the removal of dust per se for me. If you wish you can use my own E Mail for this purpose,it is many years now since I developed my methods.The variable speed control on the finishing router is an asset,my first one was a fixed speed,with so many timbers to use for pens it became essential for me to control speeds. Then there is the choice of cutters depending whether the cut is horizontal or vertical.Enjoy the journey mate.

Peter.

Thanks for the comments Peter. On this router air is sucked in at the top and blown out the bottom which clears the chips from the cutter. I will try my usual dust collector first to see how that works. The router is variable speed from 10,000 to 30,000 rpm. I’m not working to a plan as such. I’ve seen home made and commercial units that look similar in principle, just different materials. I’ve still got some details to work out. I’m waiting on some bits from China so they could take a couple of weeks.

I’m hoping to make use of some Trespa bench top material for the base and perhaps some other parts.

My finishing router in common with all finishing routers sucks air in the top a creates a whirlwind through the bottom. In my innocence I tried to remove this whirlwind accompanied by dust and shavings . No good result so I made this diverter that snugs the centre and evicts the air horizontally through the two slot exits so now from the cutter I can catch,remove and dispose of the dust etc.

I can see we are working in opposite ways to achieve our results. EG I hold my router up high vertically with the body of the router clear for me to fit the diverter to remove air away from extraction. I use several different cutters (router bits). Sorry to intrude on your posts. Good luck mate.

Peter.

 

[21William]

You're not intruding Peter, I welcome your comments. Nice idea on the extractor mod. On my old Elu router I never found the wood chips that much of a bother on most jobs and I was often using a 10 or 13mm cutter. With this lathe jig I’ll be using quite small cutters from 2mm up to maybe 8mm and V cutters.

I checked some of the dimensions this morning and one of the mounting holes was off. It was drilled in situ with the channel but in spite of using a tapping guide in the mill it was still off. I decided to have another attempt so after care positioning I plunged a 10mm mill into the motor mount on both sides then turned up a couple of threaded stainless bushes. They are held in place by a couple of cap screws seen in the picture. The slots were a bit tight so I opened them up a little and now the motor mount slides freely in the channel. The motor mount casting has some voids and is a bit crumbly in places so I’m actually happier using the steel bushes. Day off tomorrow.
