Re: Spindle Runout

Sorry to respond to this so late. Been tied up with things. Missed the reply to my question on the HF router. Unfortunately that is the same style collet we looked at before. Not a lot you can do with it with so little mating surface. Anyway, to answer your questions Scott. 4 mils is a lot if you ar...

Re: Cutting Acrylic? some help?

When cutting plastics you really need to keep your chipload up. This is due to the cut material being what keeps the tool cool. Too little chipload and you will melt the plastics. For this reason you typically don't want to use more than 2 flutes for cutting soft plastics. There are exceptions where...

Re: Are fluffy edges normal?

Looks like your bit is not right for your application. A couple quick things about bits. First, while a straight flute cutter can help with this it's not necessarily the only or best solution. A lot of times this kind of issue is caused by the rake angle of the tool. This is the angle of attack into...

Re: Where to get depth rings

Thanks, we try to get as much info out as we can. Although our backlog of stuff to put on the site keeps getting longer.

Only the drills and router bits have color coding here's a link to the legend (Link). Keep in mind I only have the white rings loose on hand. The colored ones are done en masse.

Hey Scott, if you place an order with us just put in the notes you want some extra depth rings and we'll throw them in.

Re: Creating a formula for feeds/speeds based on janka hardn

While Janka tables are a good guide for the general hardness of the woods you can't use it for a feed guide. There are many other things that have to be considered grain structure, and mineral content are two huge ones. To give you an example Ipe is actually much easier to cut then ebony. Despite th...

Re: Spindle Runout

Anyone have the dims on the harbor freight collet? Might be made by one of the big OEMs. We had one in here once and it was very different than other units. It had horrible runout too. These ones look different though. Be careful with the Chinese spindles. We have seen a lot of runout in the taper b...

Re: Makita RT0701C Collets/Endmills

Was talking to WZ9V about this in PM but I'll repeat it here. We looked at making collets for this router at the same time we were looking at the Dewalt 611. The problem is the design of the collet. There is very little clamping area. Basically only the bottom area with the cone will properly collap...

Re: What Spindle and Bit for Garolite (G10)

Thanks for the clarification Will. Here's the link to the diamond cut router feeds in copper clad ( Link ). They should be good for straight G10 as the core material is almost the same. Keep in mind you can run faster if you have a strong enough machine but will start to pick up tool deflection. RPM...

Re: What Spindle and Bit for Garolite (G10)

Sorry I'm a little late to this. PCB router bits (usually marked chip breaker or diamond cut routers) were actually made for cutting this kind of composite. They have many cutting "teeth" to give you a good cut and tool life. Doesn't hurt that they are cheap either. Personally wouldn't try it with n...
